Description:
This invention relates to portable shampooing units and more particularly, but not by way of limitation, to a portable shampooing unit which is particularly designed and constructed to be virtually self-contained and to be used for washing the hair of bedridden patients in hospitals, nursing homes and the like with a minimum of disturbance to said patients.
The washing of the hair of bedridden patients in hospitals and nursing homes as well as in private homes is very difficult for both the patient and the operator. One widespread method of cleaning or shampooing the hair of a bedridden patient is dry shampooing. This type of shampooing has not proven satisfactory, and wet shampooing of the hair is the most satisfactory method. However, with presently available equipment and methods, wet shampooing requires a substantial amount of jostling the patient around and further requires that the patient's head be moved over a tray or bowl for both the washing and rinsing phases of the shampooing operation. The tray or bowl for holding the washing and rinsing liquids as used above must be emptied often during the shampooing operation and is normally very cumbersome to handle. Applying water to the patient's hair can also be very difficult and messy in addition to the difficult problem of providing water at a comfortable temperature at the patient's bedside.
The present invention contemplates a novel portable shampooing unit for wet shampooing or washing the hair of bedridden patients and is particularly designed and constructed for overcoming the above disadvantages. The unit is first of all completely portable and can be easily rolled to a position adjacent a bedside, taking a minimum amount of space and without requiring that the usual bedside tables be moved out of the way. The present invention is compact and substantially self-contained, requiring only the provision of common electrical house power while in use. The unit is particularly designed for ease of servicing, cleaning and maintenance between uses. A very important feature of the present invention is that of being able to shampoo the patient's hair with very little disturbance to the patient and with virtually no mess whatsoever. The unit comprises a wheeled cart having a water reservoir in communication with a shampooing bowl by suitable hoses or conduits for directing the water to the bowl. A heating unit is provided on the cart for heating the shampooing water. The shampoo bowl is connected with a waste water container by suitable conduits for draining or removing the used water with a minimum of discomfort to both the patient and operator.
It is an important object of this invention to provide a novel shampooing unit for wet washing the hair of bedridden patients and which is of simple construction, compact in design and completely portable.
It is another object of this invention to provide a novel portable shampooing unit for washing the hair of bedridden patients which is substantially self-contained and requires only the provision of common electrical house power during use.
It is still another object of this invention to provide a novel portable shampooing unit for wet washing the hair of bedridden patients whereby the shampooing operation may be efficiently performed with a minimum of mess and disturbance and discomfort of the patient.
It is still another object of this invention to provide a novel portable shampooing unit for washing the hair of bedridden patients which is simple and efficient in operation and economical and durable in construction.

A lid or cover 15 is hingedly secured along the rearward edge of the housing 11 (hinges not shown) and is provided with a supporting means (not shown) for temporarily locking said lid 15 in an open position when the unit 10 is in use, as is well known. A plurality of suitable slidable storage drawers 17 are provided for the housing 11 and are preferably disposed along one side of the front of the housing 11 for storage of a wide variety of items (not shown) used in the washing and setting of hair. A door 19 is provided on the other side of the front of the housing 11 and is hingedly secured along one side thereof to the front of the housing 11 for providing access to the interior thereof.
As particularly shown in FIG. 2 a waste water tank 16 is disposed within the housing 11 in the proximity of the door 19 and is preferably rigidly mounted on or secured to the floor of the housing 14 in any well known manner (not shown). The drain or waste water tank 16 is provided with a suitable valve drain spigot (not shown) or drain port (not shown) at or near the base of the tank 16 for facilitating emptying or draining thereof, as will be hereinafter set forth. The top of the waste water tank 16 as shown herein is closed and is provided with a T-type hose connection member 21, the base of which is suitably secured to the tank top and extends downwardly therethrough for providing open communication between the interior of the tank 16 and both arms or branches of the connection member 21.
A pair of suitable conduits or flexible hoses 18 and 20 are connected to the opposite arms of the connection member 21 in the usual manner and extend outwardly therefrom in opposite directions as clearly shown in FIG. 2. The hose 18 is retractably secured against the inner periphery of one side of the housing 11 in any suitable manner, as is well known, and the hose 18 extends through a sleeve or port 22 provided in the sidewall of the housing 11. The outer end 23 of the hose 18 is preferably of a larger diameter than the port 22, or is provided with a suitable stop means whereby the outer end 23 will remain exteriorly disposed with respect to the housing 11 for facilitating manual access to the hose 18 for a purpose and in a manner as will be hereinafter set forth.
The hose 20 is retractably secured against the inner periphery of the housing oppositely disposed from the retractable connection of the hose 18, and is retractably secured in any well known manner (not shown). The hose 20 extends through a sleeve or port 24 provided in the said opposite sidewall of the housing 11, and the outer end 25 of the hose 20 is preferably of a larger diameter than the port 24, or is provided with suitable stop means whereby the outer end 25 will remain exteriorly disposed with respect to the housing 11. If desired, suitable plug members (not shown), valves (not shown), or the like may be provided for the ports 22 and 24, or for the end members 23 and 25, for selective closing thereof during use of the apparatus 10, as will be hereinafter set forth.
A cold water storage tank 26 of any suitable configuration is disposed within the housing 11 and as shown herein is preferably suitable mounted on the inside wall of the housing 11 in any well known manner (not shown). A hose coupling or sleeve member 28 is provided on the storage tank 26 and is preferably disposed in the proximity of the base or lower portion thereof for connection with a hose or conduit 27. The hose 27 is retractably secured against the inner surface of the wall of the housing 11, in any well known manner (not shown) and extends therethrough for receiving a suitable spray heat 29 on the outer end thereof.
A hot water storage tank 30 of any suitable configuration is disposed within the housing 11 and is provided with a suitable fluid transfer conduit 31 whereby hot water from the tank 30 may be transferred to the tank 26 to provide a supply of water in the tank 26 at a proper or most desirable shampooing temperature. This transfer of hot water may be accomplished by a suitable transfer pump (not shown) or by gravity feed through a suitable valve (also not shown). The hot water tank 30 is preferably mounted or secured within the housing 11 at a higher elevation than the cold water tank 26 in the event the gravity feed method is used. In addition, an electric heater 32 is also provided for the hot water tank 30 having the usual heating element (not shown) for heating the water in the storage tank 30, as is well known. The heater 32 is provided with the usual electrical power cord 33 which extends through the wall of the housing 11 and is journalled or supported by a suitable annular insulation plug 35. The outer end of the cord 33 is provided with a usual or normal electrical connector 37 which may be connected with the house power for activating the heating element 32. A suitable pump (not shown) is also provided for pumping the water from the tank 26 and through the hose 27 for a purpose as will be hereinafter set forth.
A removable or portable shampoo tray 34 is provided for the apparatus 10 and is preferably stored in one of the drawers 17 when the unit 10 is not in use, and preferably in the uppermost drawer. The shampoo tray 34, as particularly shown in FIGS. 3, 4 and 5, comprises a basic open top box portion 36 having upwardly extending side walls 39 around the peripheral edges thereof. The rear portion of the box 36 is provided with a cover plate 38 which extends forwardly over a portion of the box 36 to provide for accumulation of water in the box 36 therebelow when the tray is tilted upwardly at the front, as will be hereinafter set forth. The wall 39 disposed along the front edge of the box 36 and spaced from the cover 38 is provided with a centrally disposed arcuate recess 40 for supporting the neck of the patient therein during the hair shampooing operation. The shampoo tray 34 is supported at an angle with respect to the horizontal by suitable leg members generally indicated by reference character 42 whereby the rear portion of the tray portion 36 may be disposed at a lower elevation than the front portion thereof when the tray 34 is in use.
Oppositely disposed transversely extending drain ports 44 and 46 are provided in the side walls 39 at the rearward portion of the box 36, and a utility or spare hose 45 may be provided, if desired, for a purpose as will be hereinafter set forth. In addition, suitable valves 48 and 50 or other stop means, are provided for the drain ports 44 and 46, respectively, for permitting selective opening of the ports during use of the shampooing tray 34. The hose 45 may be conveniently stored within the housing 11 when not in use, as shown in FIG. 1.
Of course, suitable on-off switches (not shown) may be provided for the pumping apparatus, and the heating unit may also be provided with an on-off switch, if desired, or may depend merely upon connection and disconnection of the plug 37 with the usual house current for operation thereof.
It is preferable that the capacity of the tanks 16, 26 and 30 be selected for holding a sufficient quantity of liquid for assuring an adequate supply for at least one complete shampooing operation. For example, the capacity of the hot water tank 30 may be 6 gallons, the capacity of the cold water tank 26 may be 71/2 gallons and the capacity of the waste water tank 16 may be fourteen gallons. Of course, there is no intention of limiting the invention to any particular capacity size for the tanks. In addition, suitable thermostat means may be provided for the hot water tank 30 and the heater 32.
When it is desired to shampoo the hair of a bedridden patient the unit 10 may be prepared by filling the hot water storage tank 30 with water in any well known manner and partially filling the cold water storage tank 26, leaving enough storage capacity in the tank 26 to permit the addition of hot water thereto through the water transfer conduit 31 from the hot water tank 30. The unit 10 may then be rolled into a position adjacent the bedside of the bedridden patient and the heater connector 37 may be plugged into the usual electrical wall socket (not shown) as is well known for activating the heater 32 whereby the water in the tank 30 will begin heating or maintain heat if the water therein is already hot. The shampooing tray 34 may be removed from the storage drawer 17 and placed under the patient's head in a comfortable position with the patient's neck being supported by the arcuate recess 40 and the patient's head being disposed in or above the open forward portion of the box 26, said tray being disposed at an angle with respect to the horizontal that the rearward portion and associated drain ports 44 and 46 are disposed at a lower elevation than the forward portion thereof. The hot water in the tank 30 may then be added to and mixed with the water in the tank 26 through the conduit 31 to reach a desired temperature. The aforementioned pumping means (not shown) for the hot water tank 30 may be utilized for moving the hot water through the conduit 31 and into the tank 26, or the water may flow by gravity through the conduit 31. In the event the gravity flow system is utilized, it is preferable to provide a suitable valve means (not shown) for controlling the flow of the water from the tank 30. When the water in the tank 26 has reached the desired temperature, the flow of water from the tank 30 may be ceased, and the water in the tank 26 is then ready for use during a shampooing operation. Of course, should the temperature of the water in the tank 26 become too cool for comfort, as the water is used during the shampooing of the hair, additional hot water may be selectively admitted or added to the tank 26 from the tank 30. It will be apparent that a float valve (not shown) or the like, may be provided in the tank 26 for automatically stopping the flow of water from the tank 30 when the water in the tank 26 reaches a pre-determined level.
The outer end of one of the drain hoses, such as the end 23 of the hose 18 may then be connected to one of the drain ports, such as the drain port 44, of the shampooing tray 34, and the hose 18 may be pulled longitudinally for pulling the hose outwardly with respect to the housing 11. The hose 18 is then opened in the event a plug or valve member is provided therefore, and the valve 48 is opened, thus establishing a drain passageway from the shampooing tray 34 to the drain or waste water tank. Of course, the valve 50 of the port 46 is closed to preclude discharge of water therethrough. In the event the distance between the shampoo tray 34 and the housing 11 is greater than the length of the hose 18, the hose 45 may be interposed between the end 23 and the drain port 44.
The spray head 29 may then be manually grasped by the operator of the apparatus 10, and the hose 27 may be pulled outwardly from the housing 11 whereby the spray head 29 may be moved into the proximity of the shampooing tray and the head of the patient being shampooed. The pumping apparatus for the water tank 26 may be activated whereby the warm water will be delivered through the hose 27 and to the spray head 29 whereupon the shampooing operation may then be commenced in the usual manner. Of course, the pumping apparatus for the water tank 26 may be actuated by a switch or the like (not shown) provided on the hose 27 for facilitating stopping and starting of the pump in order to permit control of the flow of water to and through the spray head 29.
During the hair washing operation, the water collects in the tray of box portion 36, and the accumulated water is discharged therefrom through the open drain port 44 and is delivered through the hoses 45 and 18 into the tank 16. The shampooing tray 34 is provided with two oppositely disposed drain ports 44 and 46 and the housing 11 is provided with two drain hoses 18 and 20 in order to permit the drain hoses to be connected with the most convenient port and most convenient hose with regard to the relative position of the unit 10 with the patient, thus preventing the necessity of suspending hoses and the like across the patient's bed or any other inconvenient arrangement. The spray head 29 as shown herein is substantially centrally disposed with respect to the length of the housing 11, but it will be apparent that two outlets and two hoses may be provided from the water tank 26, if desired, with the hoses extending to the opposite sides of the housing and each being provided with independently operable spray heads.
When the hair washing operation has been completed, and the shampoo tray 34 and hose 45 have been drained, the hose 45 may be disconnected from the tray 34 and conveniently stored in the housing 11. The hoses 18, 20 and 27 may be fully retracted into the housing 11, and the shampoo tray 34 may be stored in the drawer 17. The entire unit 11 may be removed from the bedside of the patient and moved to a new site for use. Of course, the tank 16 may be drained prior to reuse of the apparatus 10 by connecting the hose 45 with the drain plug (not shown) of the tank 16 and permitting the waste water to drain into a suitable drain area, and the water tanks 26 and 30 may be refilled as hereinabove set forth in order to prepare the apparatus 10 for the next shampooing operation.
In addition, it is to be noted that the shampooing tray 34 may be utilized in and of itself as a portable shampooing apparatus, if desired. A suitable conduit or hose having a spray head provided at one end thereof may be connected at the opposite end with the usual faucet outlet of a lavatory, and a second conduit may be connected at one end with one of the drain ports of the shampoo tray and the opposite end thereof may be placed in the drain area of the lavatory, and removably secured therein in any suitable manner. The water from the lavatory may thus be utilized for washing the hair in the shampoo tray 34 and the waste water will be drained therefrom through the drain hose to the lavatory in the manner as hereinbefore set forth.
From the foregoing it will be readily apparent that the present invention provides a compact, self-contained, portable shampooing unit for washing the hair of bedridden patients which is particularly designed and constructed for efficiently and quickly wet shampooing a bedridden patient's hair with a minimal disturbance of the patient and with substantially no mess whatsoever. The novel shampooing unit is simple and efficient in operation and economical and durable in construction and is particularly designed and constructed for ease of servicing and maintenance thereof.
Whereas the present invention has been described in particular relation to the drawings attached hereto, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.
The washing of the hair of bedridden patients in hospitals and nursing homes as well as in private homes is very difficult for both the patient and the operator. One widespread method of cleaning or shampooing the hair of a bedridden patient is dry shampooing.

The outer end 23 of the hose 18 is preferably of a larger diameter than the port 22, or is provided with a suitable stop means whereby the outer end 23 will remain exteriorly disposed with respect to the housing 11 for facilitating manual access to the hose 18 for a purpose and in a manner as will be hereinafter set forth.
The hose 20 is retractably secured against the inner periphery of the housing oppositely disposed from the retractable connection of the hose 18, and is retractably secured in any well known manner (not shown). The hose 20 extends through a sleeve or port 24 provided in the said opposite sidewall of the housing 11, and the outer end 25 of the hose 20 is preferably of a larger diameter than the port 24, or is provided with suitable stop means whereby the outer end 25 will remain exteriorly disposed with respect to the housing 11. If desired, suitable plug members (not shown), valves (not shown), or the like may be provided for the ports 22 and 24, or for the end members 23 and 25, for selective closing thereof during use of the apparatus 10, as will be hereinafter set forth.
A cold water storage tank 26 of any suitable configuration is disposed within the housing 11 and as shown herein is preferably suitable mounted on the inside wall of the housing 11 in any well known manner (not shown). A hose coupling or sleeve member 28 is provided on the storage tank 26 and is preferably disposed in the proximity of the base or lower portion thereof for connection with a hose or conduit 27. The hose 27 is retractably secured against the inner surface of the wall of the housing 11, in any well known manner (not shown) and extends therethrough for receiving a suitable spray heat 29 on the outer end thereof.
A hot water storage tank 30 of any suitable configuration is disposed within the housing 11 and is provided with a suitable fluid transfer conduit 31 whereby hot water from the tank 30 may be transferred to the tank 26 to provide a supply of water in the tank 26 at a proper or most desirable shampooing temperature. This transfer of hot water may be accomplished by a suitable transfer pump (not shown) or by gravity feed through a suitable valve (also not shown). The hot water tank 30 is preferably mounted or secured within the housing 11 at a higher elevation than the cold water tank 26 in the event the gravity feed method is used. In addition, an electric heater 32 is also provided for the hot water tank 30 having the usual heating element (not shown) for heating the water in the storage tank 30, as is well known. The heater 32 is provided with the usual electrical power cord 33 which extends through the wall of the housing 11 and is journalled or supported by a suitable annular insulation plug 35. The outer end of the cord 33 is provided with a usual or normal electrical connector 37 which may be connected with the house power for activating the heating element 32. A suitable pump (not shown) is also provided for pumping the water from the tank 26 and through the hose 27 for a purpose as will be hereinafter set forth.
A removable or portable shampoo tray 34 is provided for the apparatus 10 and is preferably stored in one of the drawers 17 when the unit 10 is not in use, and preferably in the uppermost drawer. The shampoo tray 34, as particularly shown in FIGS. 3, 4 and 5, comprises a basic open top box portion 36 having upwardly extending side walls 39 around the peripheral edges thereof. The rear portion of the box 36 is provided with a cover plate 38 which extends forwardly over a portion of the box 36 to provide for accumulation of water in the box 36 therebelow when the tray is tilted upwardly at the front, as will be hereinafter set forth. The wall 39 disposed along the front edge of the box 36 and spaced from the cover 38 is provided with a centrally disposed arcuate recess 40 for supporting the neck of the patient therein during the hair shampooing operation. The shampoo tray 34 is supported at an angle with respect to the horizontal by suitable leg members generally indicated by reference character 42 whereby the rear portion of the tray portion 36 may be disposed at a lower elevation than the front portion thereof when the tray 34 is in use.
Oppositely disposed transversely extending drain ports 44 and 46 are provided in the side walls 39 at the rearward portion of the box 36, and a utility or spare hose 45 may be provided, if desired, for a purpose as will be hereinafter set forth. In addition, suitable valves 48 and 50 or other stop means, are provided for the drain ports 44 and 46, respectively, for permitting selective opening of the ports during use of the shampooing tray 34. The hose 45 may be conveniently stored within the housing 11 when not in use, as shown in FIG. 1.
Of course, suitable on-off switches (not shown) may be provided for the pumping apparatus, and the heating unit may also be provided with an on-off switch, if desired, or may depend merely upon connection and disconnection of the plug 37 with the usual house current for operation thereof.
It is preferable that the capacity of the tanks 16, 26 and 30 be selected for holding a sufficient quantity of liquid for assuring an adequate supply for at least one complete shampooing operation. For example, the capacity of the hot water tank 30 may be 6 gallons, the capacity of the cold water tank 26 may be 71/2 gallons and the capacity of the waste water tank 16 may be fourteen gallons. Of course, there is no intention of limiting the invention to any particular capacity size for the tanks. In addition, suitable thermostat means may be provided for the hot water tank 30 and the heater 32.
When it is desired to shampoo the hair of a bedridden patient the unit 10 may be prepared by filling the hot water storage tank 30 with water in any well known manner and partially filling the cold water storage tank 26, leaving enough storage capacity in the tank 26 to permit the addition of hot water thereto through the water transfer conduit 31 from the hot water tank 30. The unit 10 may then be rolled into a position adjacent the bedside of the bedridden patient and the heater connector 37 may be plugged into the usual electrical wall socket (not shown) as is well known for activating the heater 32 whereby the water in the tank 30 will begin heating or maintain heat if the water therein is already hot. The shampooing tray 34 may be removed from the storage drawer 17 and placed under the patient's head in a comfortable position with the patient's neck being supported by the arcuate recess 40 and the patient's head being disposed in or above the open forward portion of the box 26, said tray being disposed at an angle with respect to the horizontal that the rearward portion and associated drain ports 44 and 46 are disposed at a lower elevation than the forward portion thereof. The hot water in the tank 30 may then be added to and mixed with the water in the tank 26 through the conduit 31 to reach a desired temperature. The aforementioned pumping means (not shown) for the hot water tank 30 may be utilized for moving the hot water through the conduit 31 and into the tank 26, or the water may flow by gravity through the conduit 31. In the event the gravity flow system is utilized, it is preferable to provide a suitable valve means (not shown) for controlling the flow of the water from the tank 30. When the water in the tank 26 has reached the desired temperature, the flow of water from the tank 30 may be ceased, and the water in the tank 26 is then ready for use during a shampooing operation. Of course, should the temperature of the water in the tank 26 become too cool for comfort, as the water is used during the shampooing of the hair, additional hot water may be selectively admitted or added to the tank 26 from the tank 30. It will be apparent that a float valve (not shown) or the like, may be provided in the tank 26 for automatically stopping the flow of water from the tank 30 when the water in the tank 26 reaches a pre-determined level.
The outer end of one of the drain hoses, such as the end 23 of the hose 18 may then be connected to one of the drain ports, such as the drain port 44, of the shampooing tray 34, and the hose 18 may be pulled longitudinally for pulling the hose outwardly with respect to the housing 11. The hose 18 is then opened in the event a plug or valve member is provided therefore, and the valve 48 is opened, thus establishing a drain passageway from the shampooing tray 34 to the drain or waste water tank. Of course, the valve 50 of the port 46 is closed to preclude discharge of water therethrough. In the event the distance between the shampoo tray 34 and the housing 11 is greater than the length of the hose 18, the hose 45 may be interposed between the end 23 and the drain port 44.
The spray head 29 may then be manually grasped by the operator of the apparatus 10, and the hose 27 may be pulled outwardly from the housing 11 whereby the spray head 29 may be moved into the proximity of the shampooing tray and the head of the patient being shampooed. The pumping apparatus for the water tank 26 may be activated whereby the warm water will be delivered through the hose 27 and to the spray head 29 whereupon the shampooing operation may then be commenced in the usual manner. Of course, the pumping apparatus for the water tank 26 may be actuated by a switch or the like (not shown) provided on the hose 27 for facilitating stopping and starting of the pump in order to permit control of the flow of water to and through the spray head 29.
During the hair washing operation, the water collects in the tray of box portion 36, and the accumulated water is discharged therefrom through the open drain port 44 and is delivered through the hoses 45 and 18 into the tank 16. The shampooing tray 34 is provided with two oppositely disposed drain ports 44 and 46 and the housing 11 is provided with two drain hoses 18 and 20 in order to permit the drain hoses to be connected with the most convenient port and most convenient hose with regard to the relative position of the unit 10 with the patient, thus preventing the necessity of suspending hoses and the like across the patient's bed or any other inconvenient arrangement. The spray head 29 as shown herein is substantially centrally disposed with respect to the length of the housing 11, but it will be apparent that two outlets and two hoses may be provided from the water tank 26, if desired, with the hoses extending to the opposite sides of the housing and each being provided with independently operable spray heads.
When the hair washing operation has been completed, and the shampoo tray 34 and hose 45 have been drained, the hose 45 may be disconnected from the tray 34 and conveniently stored in the housing 11. The hoses 18, 20 and 27 may be fully retracted into the housing 11, and the shampoo tray 34 may be stored in the drawer 17. The entire unit 11 may be removed from the bedside of the patient and moved to a new site for use. Of course, the tank 16 may be drained prior to reuse of the apparatus 10 by connecting the hose 45 with the drain plug (not shown) of the tank 16 and permitting the waste water to drain into a suitable drain area, and the water tanks 26 and 30 may be refilled as hereinabove set forth in order to prepare the apparatus 10 for the next shampooing operation.
In addition, it is to be noted that the shampooing tray 34 may be utilized in and of itself as a portable shampooing apparatus, if desired. A suitable conduit or hose having a spray head provided at one end thereof may be connected at the opposite end with the usual faucet outlet of a lavatory, and a second conduit may be connected at one end with one of the drain ports of the shampoo tray and the opposite end thereof may be placed in the drain area of the lavatory, and removably secured therein in any suitable manner. The water from the lavatory may thus be utilized for washing the hair in the shampoo tray 34 and the waste water will be drained therefrom through the drain hose to the lavatory in the manner as hereinbefore set forth.
From the foregoing it will be readily apparent that the present invention provides a compact, self-contained, portable shampooing unit for washing the hair of bedridden patients which is particularly designed and constructed for efficiently and quickly wet shampooing a bedridden patient's hair with a minimal disturbance of the patient and with substantially no mess whatsoever. The novel shampooing unit is simple and efficient in operation and economical and durable in construction and is particularly designed and constructed for ease of servicing and maintenance thereof.
Whereas the present invention has been described in particular relation to the drawings attached hereto, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.
