The present invention relates to medical supplies for hospitals and, more particularly, provides a double-container fluid bottle suitable for receiving urinary tract drainage liquid, for example, from hospitalized patients.

In many instances, there is required for hospital use some type of vessel which may be constructed to store successive, separately measurable, storage charges of liquid such as liquid released during urinary tract drainage of hospitalized patients. What is needed, the inventor has discovered, is a valved container-within-a-container approach. Thus, where interior and exterior containers are used, both being transparent, with the first being graduated valved for periodic flow into the second, then the interior graduated container may be used to measure the amount of fluid or liquid drained within a given interval of time into such structure. After a pre-determined time period has elapsed, then the nurse or other medical personnel, by the structure of the present invention, may release the liquid charge of the interior container such as the same escapes into the lowermost part of the outermost container utilized. The latter can be capped or its outlet tube pinched off, to accommodate intermittent storage and final drainage into a pail or other waste disposal vessel.

The present invention affords a double-container approach, with the first or interior container being graduated and being disposed above the bottle of the second or exterior container. The uppermost or graduated container is provided with an actuatable stem-type valve which can be selectively actuated to drain the interior container.

Preferably, the bottom of the interior container is canted or sloped so that a complete drainage to the valving portion thereof may be accommodated.

A suitable support strap is provided for single or preferably a double-lock support over a bracket or other support object. The strap is also provided with an aperture providing a through-routing of a drainage hose or conduit connected to the system. A tortuous path is provided as a bacteria trap, preferably both interiorly of the bottle or container structure, and also exteriorly thereof, proximate the fluid drainage inlet to the bottle. A suitable, filter air intake is likewise supplied the bottle to accommodate escape of air from the bottle as liquid is being introduced therein. An anti-splash tube is incorporated within the interior container and is supported by the lid thereof, this to prevent foaming proximate the lower most region of the interior graduated container.

Accordingly, a principal object of the present invention is to provide a new and improved, double container bottle structure for medical uses.

A further object of the invention is to provide a new and improved support means for fluid containers to be supported from a projection such as a bracket.

An additional object is to provide a bottle or container structure suitable for periodically measuring drainage from urinary tracts of hospitalized persons.

A further object of the invention is to provide a double container structure, i.e., a valved interior container disposed completely within an exterior container, and this such that the interior container may be used to measure successive amounts of fluid immediately prior to drainage of such successive amounts into the lowermost region of the exterior container.

A further object is to provide single and preferably double bacteria traps for hospital drainage bottles, this such that a trap is disposable interior of the bottle and also exterior thereto proximate the fluid admittance port of the construction.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further object and advantages thereof, may best be understood by reference to the following description, taken in connection with the accompanying drawings in which:

FIG. 1 is a perspective view of a bottle or container constructed in accordance with the principles of the present invention; for convenience of illustration the support strap thereof is shown in fragmentary view.

FIG. 2 is an enlarged fragmentary detail of a portion of the structure relating to the lid in FIG. 1, such structure providing air access to the interior of the composite bottle of FIG. 1.

FIG. 3 is a perspective view of the support strap shown in fragmentary view in FIG. 1; for convenience of illustration the non-developed extensions of the support strap are illustrated in phantom line, the solid lines showing the two ends of the support strap being secured together in a double-locked juncture.

FIG. 4 is an enlarged fragmentary detail illustrating a representative outlet for the outer container of the structure, FIG. 1.

FIG. 5 is an enlarged fragmentary view, principally in section, of the fluid inlet port utilized in the present invention, see the upper left-hand portion of FIG. 1.

FIG. 6 is a section view, shown in reduced scale relative to FIG. 5, illustrating that fluid inlet portion of the lid structure which cooperates with the lower part of FIG. 5, leading thereto.

FIG. 7 is a fragmentary detail, shown in section, of the interior of the container enclosure; in FIG. 7, the rod valve is closed such that fluid L is contained within the interior container.

FIG. 8 is similar to FIG. 7 but illustrates the manner in which fluid is drained from the interior container into the exterior container.

FIG. 9 is a plan view of the interior plate used in the structure by which the interior container is supported by the exterior container.

In FIG. 1, bottle 10 includes a container 11 provided with a lid 12. Lid 12 includes a top 13 and upstanding ports 14 and 15 as illustrated. Port 15 connects to an elbow 16 which is detailed in FIG. 2 and includes an air filter 17 cemented to elbow end 18; filter 17 is made perforate at 19 and 20 and being provided with a cotton or other filter material 21. Patient tube 22 is inserted at its upper extremity 23 into connector 24. It will be noted that the interior of the connector 24, see FIG. 5, is spaced from the end of hose or conduit 22. This is for the purpose of providing a trap or tortuous path such that bacteria will not creep past the juncture of the connector and conduit. A flexible sleeve 27 is pressed over the lower stem 28 of connector 24, see FIG. 1. Port 14 may be tapered in the usual manner.

Supporting the container is a container strap 30, the same including a ring portion 31, and upper strap members 32 and 33. Upper strap member 32 includes two T-configured slots 34 and 35, whereas upper strap member 33 includes opposite side notches 36 and 37. Notches 36 and 37 in essence form insert tabs 38 and 39 which are contiguous as illustrated and which fit together in a double lock in the manner illustrated in slotted line configuration at 40 in FIG. 3.

Accordingly, the side of the bottle 10 may be tapered and the strap may be formed of polyethylene and be cylindrical, by way of example, so that the strap will either frictionally and wedgingly engage the container or be disposed underneath a provided shoulder 41 thereof to support the same. The double locking feature of the strap as shown in FIG. 3 is deemed important and provides a positive connection whereby the container may be suspended for a suitable support.

Disposed at the bottom of the structure shown in FIG. 1 is a tube 42 which is inserted in container aperture 43 and may be provided with the usual on-off shut off clip 45. The latter is conventional in form and is shown simply schematically in FIG. 4. The tube 42 itself is inserted through aperture 43, see FIG. 4, to be disposed in communication with the bottom 44 of the container 11.

FIG. 5 is a further illustration of the upper portion of the structure at 24, illustrating that the doubled-back configurement at 46 and 47 relative to member 24 provides a tortuous path which is least likely to provide a bacterial path between connector 24 and the tubing at 22. In medical practice it is believed, and there is substantial evidence to confirm this belief, that bacteria is most likely to travel along a straight path and is least likely to travel along a tortuous or doubled-back path. It is the doubled-back path provided in the upper portion of FIG. 5 which is deemed of importance. Likewise, in fact there may be provided a second trap so that the structure is provided a double bacterial trap, by virtue of the structure shown in both FIGS. 5 and 6. In FIG. 6 the lid 12 now includes the upstanding port 28, corresponding to port 14 as before described, which port preferably includes a depending extension 48 and also transversely arcuately curved fingers 49 and 50. The latter serve as spread-type mounting elements for mounting a flexible, depending, anti-splash tube 51. It is seen that here again there is provided a tortuous path as between the interior of tube 51 beneath extremity E and the interior portion leading arcuately around area 53 to such extremity E. Thus, there is an effective doubled-back bacteria trap in connection with each structure shown in FIG. 5 and FIG. 6.

FIG. 7 shows in sectional view the interior of the container 11. Specifically, and see also FIG. 9, the same may include an upper plate 54 which is perforate at 55, 56 and 57. The first two perforations are for air access and also fluid overflow from the inner container, whereas the last aperture, aperture 57' is for the purpose of receiving and mounting a depending graduated tube or inner container 58. Interior graduated container 58 is graduated at 59 in desired volume increments. Portion 60 of plate 54 includes upstanding rib 61 serving essentially as a track upon which the lower extremity E' of FIG. 2 can ride or at least can rest. It will be noted that there will be air communication as between E' and the remainder of the structure, specifically the interior of the bottle. It is noted that upstanding margin 62 forms, in effect, a weir so as to prevent any fluid resting on the top surface of the plate from entering into the air escape chamber proximate the recesses adjacent ribs 61.

It is preferable that the bottom B of the interior container 64 be canted or tapered in the manner illustrated in FIG. 7. In any event, a tubular cylinder 65 will be sealed to the bottle interior at 66 and likewise sealed within an aperture 67 of the interior container. A rod 68 includes an arcuate handle 69 which can be selectively withdrawn, as shown in FIG. 8, or returned to its original position as illustrated in FIG. 7. Rod 68 serves as a valve which confines a liquid L in the interior container as shown in FIG. 7, or which allows the same to escape as through wall aperture 71 in tube 65, as shown in FIG. 8.

In operation, the subject bottle ideally serves as a urinary tract drainage system, with hose 22 being routed to a patient and also connected to the container as shown, see FIG. 1. By gravity flow, liquid passes through the hose or tubing 22 down past the double-trap heretofore explained to the interior of graduated interior container 58. With the rod type valve closed, as shown in FIG. 7, the fluid of course is confined within the graduated cylinder 58 and, since both inner container 58 and outer container 11 are transparent, manufactured by transparent polyethelene, for example, the graduations 59 can conveniently be read from the exterior.

Accordingly, over given time intervals, the specific amount of drainage that is involved can be conveniently read. Thereafter, the user may simply withdraw the plunger or rod 68 by withdrawing upon handle 69, see FIGS. 7 and 8, so that liquid falls in the direction of the arrow shown in FIG. 8 to the bottom of the bottle. The tube closure or clip 45 is retained closed until the user medical personnel wish to drain the bottom of the unit, at which time the closure is opened and a suitable vessel provided underneath the outer extremity of the hose 42 in FIG. 4, so as to withdraw the contents within the larger vessel, that is within container 11.

Accordingly, the structure provides for a periodic readings of intermittent drainages of urinary tract liquid, thus to compare volumes for given time spans, and with the intermittent volumes being intermittently measurable and subsequently released to a general reservoir as provided at R (see FIG. 1) within the outer container 11 or for ultimate drainage from outlet tube 42.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects, and within the true spirit and scope of the invention.
