Medical instrument retainer
United States Patent 3895629
A garment to retain a medical instrument in position at the perineum is formed with mutually overlapping and detachable interconnected bifurcated crotch panels that collectively define an instrument gripping aperture. The bifurcations permit the overlapping panels to be connected to each other or disconnected from each other in operative relation to the emplaced medical instrument without removing the instrument or disconnecting it from external apparatus. An absorbent dressing has an aperture in communication with an edge of the dressing by means of a slit extending through the dressing so that the dressing too may be positioned about and removed from the emplaced medical instrument without disturbing the instrument.

Description:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to medical instruments and more particularly concerns the retention of an instrument emplaced within a body aperture.
2. Description of Prior Art
In various types of medical operations, and particularly in post-operative procedures, a tubular instrument is emplaced within a body opening to facilitate passage of urine. Such instruments are employed for administration of various fluids into the intestinal tract, for example, and for the drainage and extraction of fluids from body cavities or internal surgical sites. For example, in the relatively frequently performed hysterectomy, postoperative procedure often requires the placement of a catheter within the urethra to facilitate the passage of urine. The catheter will often remain in place for several days or more, being retained in that position continuously or nearly continuously throughout this period. Further, an appropriate dressing or absorbent packing is often placed against the body at and circumscribing the projecting catheter, and such dressing may be changed more frequently than the catheter is removed or is desired to be removed.
In order to minimize both discomfort and pain, the emplaced projecting catheter must be properly positioned. It must be free of disturbing forces and firmly retained in such position so that its movement and the concomitant disturbance of sensitive internal body tissues may be minimized. Garments and dressings heretofore available for permitting the passage of instruments into the body or for positioning such instruments in site are described in U.S. Pat. No. 3,286,713 to Kurtz et al. and U.S. Pat. No. 3,765,401 to Vass. The patent to Kurtz et al merely describes a dressing with a deformable aperture therethrough that may be enlarged to facilitate insertion of a tubular instrument. The patent to Vass describes a belted device for sustaining an instrument devised for administration of fluids into the intestinal tract through the rectum, and embodies an elongated rigid rectangular-section bridge that has a collar and aperture to be slipped over the free end of a projecting, tubular instrument. The apparatus of Vass is believed to be painful and uncomfortable for any lengthy period of use. Both the apparatus of Vass and that of Kurtz et al. require removal or disconnection of the instrument so that it may be inserted through the aperture of the dressing or sustaining belt. Prior devices do not suggest application and removal of dressings and/or dressing-retaining garments without significantly disturbing the projecting instrument.
Accordingly, it is an object of the present invention to provide a medical instrument retainer which minimizes or eliminates the above-mentioned disadvantages.
SUMMARY OF THE INVENTION
In carrying out principles of the present invention in accordance with a preferred embodiment thereof, a retainer is formed of first and second bifurcated panels each having mutually spaced branches defining open-ended slots therebetween. The branches are detachably connected in respective overlapping relation and in mutually opposite orientation along the longitudinal extent of the slots to define an aperture bounded by and between the bight portions of the slots, whereby the retainer may be positioned with its aperture circumscribing an instrument without removing the instrument from the body aperture and without disconnecting the instrument from other apparatus to which it may be connected.

DETAILED DESCRIPTION
As illustrated in FIGS. 1, 2, 3 and 4, a retainer garment embodying principles of the present invention is formed of front and back garment sections 10 and 12 cut from a soft, somewhat resilient or elastic fabric. The two sections are substantially similar to each other, the front section being somewhat smaller, and both shaped as illustrated to afford a comfortable fit upon a human body. The two sections have upper portions 14 and 16, respectively, that extend laterally into body attachment portions 18, 20 and 22, 24. Body attachment portions 18, 20 of one of the sections, such as, for example, the rear section, are relatively longer than the corresponding portions 22, 24 of the other section, the front section, to provide for adjustability to different waist sizes. The longer attachment portions are provided with elongated connecting devices 26, 28 which may be of any suitable type, such as snap fasteners, buttons or one part of the Velcro fastener. Attachment portions 22, 24 have fixed thereto connecting devices 30, 32 that are complementary to the connecting devices 26, 28, respectively, and may comprise buttons, button holes, snap fasteners or the second parts of the Velcro fasteners.
Although the upper or waist-encircling sections 14, 16 of the front and back garment sections are made with detachable waist-encircling connections, it will be readily appreciated that these waist-encircling sections may be continuous and non-detachable since the garment is not to be removed from the waist of the wearer when changing the dressing, as will be more particularly described below.
The front section 10 is formed with an integral frontal apron 34 that provides a relatively narrow bifurcated crotch panel 36 having first and second arms or branches 38, 40 that are laterally spaced from each other to define an elongated open-ended slot 42 terminating at an inward part of the crotch panel in a bight 44. Fastener parts, such as snap fasteners, buttons or Velcro devices 46, 48 are affixed to arms 38, 40, respectively, of the bifurcated crotch panel 36.
The back section, which is similar to the front section, is formed with a dorsal apron 50 and includes a narrowed bifurcated crotch panel 52 having arms 54, 56 laterally spaced from each other to define a narrow elongated slot 58 terminating at an inner end of the crotch panel in a bight 60. Fastener parts 62, 64 are fixedly secured to the crotch panel 52 to mate with and detachably connect to the fastener parts 46, 48 of the crotch panel 36. Velcro-type fastening means are employed in a preferred embodiment for maximum comfort, convenience and adjustability. Both crotch panels, if deemed necessary or desirable, may be formed with a double layer of the material from which the garment is made in order to reinforce this portion of the garment. Similarly, the body attachment portions 18, 20, 22 and 24 may be reinforced by additional layers of the same or other strengthening material for strengthening the securement of the connecting devices 26, 28, 30 and 32.
The two crotch sections are substantially identical with each other and are dimensioned and configured so that arm 38 may overlap arm 54, and arm 40 may overlap arm 56 for a major portion of their length, as illustrated in the plan view of FIG. 4.
Although the arms or branches overlap for most of their length, the extent of each overlap is less than the full length of the branches, or more specifically, less than the full length of the slots that are defined between adjacent branches of each section. Thus, when the two crotch panels are connected in the overlapping relation illustrated in FIG. 4, the two bights 44 and 60 are still spaced from each other along the extent of the slots and thus collectively define between the bights a completely closed gripping aperture 68 that is bounded by and between the overlapping branches and opposed bights of the crotch panels.
For use with the retainer garment of FIGS. 1, 2, 3 and 4, there is provided a dressing or flexible absorbent pad 70 illustrated in FIG. 5. Pad 70 is a conventional dressing or absorbent pad such as a standard sanitary napkin that is apertured as at 72 and cut to form a slot 74 that extends between the aperture 72 and one edge 76 of the pad. Accordingly, the pad may be distorted to separate the two normally abutting sides of the slot 74 and the pad may be moved laterally relative to a tubular instrument to allow the latter to move transversely of its length along the slot to the aperture 72. The pad, of course, may be removed with a similar but oppositely directed motion, both being accomplished without disturbing the relation of the tubular instrument with respect to the body aperture from which it may project.
A significant feature of the invention is the ability of the retainer garment to be connected and disconnected from its retaining engagement with a tubular instrument without disturbing the instrument. Thus, as illustrated in the fragmentary view of FIG. 6, the two crotch panels 36, 52 may be moved to snug engaging relation with respect to a tubular instrument 80 that projects from a body aperture by moving the two crotch panels toward each other, as indicated by arrows 82, 84. This causes each slot 42, 58 to slide over and transversely of the tube and into overlapping relation with the slot of the other crotch panel until the respective bights 44, 60 snugly engage opposite halves of the exterior of the instrument 80. Overlapping arms 38, 54 and 40, 56 are now pressed against each other to complete the connection between the several connecting devices 46, 62 and 48, 64. The tube 80 is now snugly engaged within and retained by the aperture 68 that is bounded by the arms of the two bifurcated crotch panels. The two crotch panels may be pulled relatively tightly against the tube to achieve a snug engagement in which the area of the crotch panel arms adjacent the bights thereof is slightly deformed to cause the material of the crotch panels to engage the external surface of the tube over relatively greater lengths (greater than the thickness of the crotch panel material) of the tube adjacent the crotch panel.
With the two crotch panels in connected overlapping relation, or in the alternative, before the two crotch panels have been joined, the dressing or absorbent pad 70 may be placed about the tube 80. This is achieved by relative motion of the several parts, as illustrated in the fragmentary plan view of FIG. 7. Thus, the two crotch panels 36, 52 may be moved as indicated by the arrows 82, 84 in the manner described above and, thereafter, the pad 70 may be interposed between the connected overlapped crotch panels and the body of the garment wearer by pulling the crotch panels away from the wearer's body and laterally sliding the dressing 70 with respect to the tube 80 so that the latter will traverse the opened cut 74 and enter the aperture 72. Alternatively, the dressing or pad 70 may be placed as described, before the crotch panels are engaged and connected. Thereafter, the crotch panels may be brought together in overlapping relation over the previously emplaced pad 70 and into snug engagement with the tube 80.
Conversely, the dressing 70 may be removed without detaching the two crotch panels, or the latter may be detached and then the dressing may be removed. In any event, the dressing may be emplaced and removed, and the instrument retaining crotch panels may be emplaced and removed all without either removing the tube from the body aperture or disconnecting the tube from external apparatus to which it may be connected to the body of the wearer, being securely engaged to and about the wearer's waist. The firm securement of the waist or body attaching portions to the wearer's waist, the elasticity of the fit of the garment about the waist and thighs of the wearer and the longitudinally adjustable overlapping of panel arms, all tend to snugly and firmly retain the garment in a fixed position upon the wearer's body. Since the garment as a whole is retained in a fixed position with respect to the wearer's body, the garment aperture 44 is also fixedly positioned. Since the aperture 44 firmly engages the tubular instrument 80, the latter is firmly retained in appropriate position in the body aperture. The arrangement provides a self-centering of the gripping aperture which, in effect, is formed in place about the emplaced instrument.
The described arrangement for connecting the two crotch panels by moving these toward each other as indicated in FIGS. 6 and 7 automatically adjusts the garment in a proper position upon the wearer so that the crotch panel aperture 44 is properly positioned in snug retaining engagement with the tube 80.
Although the snug fit of the garment, which is enchanced by the adjustability of the several connecting parts is sufficient in and of itself to retain in position a dressing that is interposed between the crotch panels and the body of the wearer, each garment section may have an elastic band 86, 88 secured at respective ends of the bands to inner surfaces of the garment adjacent inner ends of the crotch panels. These bands will aid in maintaining a fixed orientation of the dressing 70 and minimize any tendency of the dressing to move angularly about the tube 80 as an axis.
There has been disclosed an improved retainer and dressing for use with a medical instrument placed in a body opening that permits positioning and removal of the garment and the dressing without disturbing the instrument, but enables firm securement and self-centering of the garment upon the tube.
The foregoing detailed description is to be clearly understood as given by way of illustration and example only, the spirit and scope of this invention being limited solely by the appended claims.

DETAILED DESCRIPTION
As illustrated in FIGS. 1, 2, 3 and 4, a retainer garment embodying principles of the present invention is formed of front and back garment sections 10 and 12 cut from a soft, somewhat resilient or elastic fabric. The two sections are substantially similar to each other, the front section being somewhat smaller, and both shaped as illustrated to afford a comfortable fit upon a human body. The two sections have upper portions 14 and 16, respectively, that extend laterally into body attachment portions 18, 20 and 22, 24. Body attachment portions 18, 20 of one of the sections, such as, for example, the rear section, are relatively longer than the corresponding portions 22, 24 of the other section, the front section, to provide for adjustability to different waist sizes. The longer attachment portions are provided with elongated connecting devices 26, 28 which may be of any suitable type, such as snap fasteners, buttons or one part of the Velcro fastener. Attachment portions 22, 24 have fixed thereto connecting devices 30, 32 that are complementary to the connecting devices 26, 28, respectively, and may comprise buttons, button holes, snap fasteners or the second parts of the Velcro fasteners.
Although the upper or waist-encircling sections 14, 16 of the front and back garment sections are made with detachable waist-encircling connections, it will be readily appreciated that these waist-encircling sections may be continuous and non-detachable since the garment is not to be removed from the waist of the wearer when changing the dressing, as will be more particularly described below.
The front section 10 is formed with an integral frontal apron 34 that provides a relatively narrow bifurcated crotch panel 36 having first and second arms or branches 38, 40 that are laterally spaced from each other to define an elongated open-ended slot 42 terminating at an inward part of the crotch panel in a bight 44. Fastener parts, such as snap fasteners, buttons or Velcro devices 46, 48 are affixed to arms 38, 40, respectively, of the bifurcated crotch panel 36.
The back section, which is similar to the front section, is formed with a dorsal apron 50 and includes a narrowed bifurcated crotch panel 52 having arms 54, 56 laterally spaced from each other to define a narrow elongated slot 58 terminating at an inner end of the crotch panel in a bight 60. Fastener parts 62, 64 are fixedly secured to the crotch panel 52 to mate with and detachably connect to the fastener parts 46, 48 of the crotch panel 36. Velcro-type fastening means are employed in a preferred embodiment for maximum comfort, convenience and adjustability. Both crotch panels, if deemed necessary or desirable, may be formed with a double layer of the material from which the garment is made in order to reinforce this portion of the garment. Similarly, the body attachment portions 18, 20, 22 and 24 may be reinforced by additional layers of the same or other strengthening material for strengthening the securement of the connecting devices 26, 28, 30 and 32.
The two crotch sections are substantially identical with each other and are dimensioned and configured so that arm 38 may overlap arm 54, and arm 40 may overlap arm 56 for a major portion of their length, as illustrated in the plan view of FIG. 4.
Although the arms or branches overlap for most of their length, the extent of each overlap is less than the full length of the branches, or more specifically, less than the full length of the slots that are defined between adjacent branches of each section. Thus, when the two crotch panels are connected in the overlapping relation illustrated in FIG. 4, the two bights 44 and 60 are still spaced from each other along the extent of the slots and thus collectively define between the bights a completely closed gripping aperture 68 that is bounded by and between the overlapping branches and opposed bights of the crotch panels.
For use with the retainer garment of FIGS. 1, 2, 3 and 4, there is provided a dressing or flexible absorbent pad 70 illustrated in FIG. 5. Pad 70 is a conventional dressing or absorbent pad such as a standard sanitary napkin that is apertured as at 72 and cut to form a slot 74 that extends between the aperture 72 and one edge 76 of the pad. Accordingly, the pad may be distorted to separate the two normally abutting sides of the slot 74 and the pad may be moved laterally relative to a tubular instrument to allow the latter to move transversely of its length along the slot to the aperture 72. The pad, of course, may be removed with a similar but oppositely directed motion, both being accomplished without disturbing the relation of the tubular instrument with respect to the body aperture from which it may project.
A significant feature of the invention is the ability of the retainer garment to be connected and disconnected from its retaining engagement with a tubular instrument without disturbing the instrument. Thus, as illustrated in the fragmentary view of FIG. 6, the two crotch panels 36, 52 may be moved to snug engaging relation with respect to a tubular instrument 80 that projects from a body aperture by moving the two crotch panels toward each other, as indicated by arrows 82, 84. This causes each slot 42, 58 to slide over and transversely of the tube and into overlapping relation with the slot of the other crotch panel until the respective bights 44, 60 snugly engage opposite halves of the exterior of the instrument 80. Overlapping arms 38, 54 and 40, 56 are now pressed against each other to complete the connection between the several connecting devices 46, 62 and 48, 64. The tube 80 is now snugly engaged within and retained by the aperture 68 that is bounded by the arms of the two bifurcated crotch panels. The two crotch panels may be pulled relatively tightly against the tube to achieve a snug engagement in which the area of the crotch panel arms adjacent the bights thereof is slightly deformed to cause the material of the crotch panels to engage the external surface of the tube over relatively greater lengths (greater than the thickness of the crotch panel material) of the tube adjacent the crotch panel.
With the two crotch panels in connected overlapping relation, or in the alternative, before the two crotch panels have been joined, the dressing or absorbent pad 70 may be placed about the tube 80. This is achieved by relative motion of the several parts, as illustrated in the fragmentary plan view of FIG. 7. Thus, the two crotch panels 36, 52 may be moved as indicated by the arrows 82, 84 in the manner described above and, thereafter, the pad 70 may be interposed between the connected overlapped crotch panels and the body of the garment wearer by pulling the crotch panels away from the wearer's body and laterally sliding the dressing 70 with respect to the tube 80 so that the latter will traverse the opened cut 74 and enter the aperture 72. Alternatively, the dressing or pad 70 may be placed as described, before the crotch panels are engaged and connected. Thereafter, the crotch panels may be brought together in overlapping relation over the previously emplaced pad 70 and into snug engagement with the tube 80.
Conversely, the dressing 70 may be removed without detaching the two crotch panels, or the latter may be detached and then the dressing may be removed. In any event, the dressing may be emplaced and removed, and the instrument retaining crotch panels may be emplaced and removed all without either removing the tube from the body aperture or disconnecting the tube from external apparatus to which it may be connected to the body of the wearer, being securely engaged to and about the wearer's waist. The firm securement of the waist or body attaching portions to the wearer's waist, the elasticity of the fit of the garment about the waist and thighs of the wearer and the longitudinally adjustable overlapping of panel arms, all tend to snugly and firmly retain the garment in a fixed position upon the wearer's body. Since the garment as a whole is retained in a fixed position with respect to the wearer's body, the garment aperture 44 is also fixedly positioned. Since the aperture 44 firmly engages the tubular instrument 80, the latter is firmly retained in appropriate position in the body aperture. The arrangement provides a self-centering of the gripping aperture which, in effect, is formed in place about the emplaced instrument.
The described arrangement for connecting the two crotch panels by moving these toward each other as indicated in FIGS. 6 and 7 automatically adjusts the garment in a proper position upon the wearer so that the crotch panel aperture 44 is properly positioned in snug retaining engagement with the tube 80.
Although the snug fit of the garment, which is enchanced by the adjustability of the several connecting parts is sufficient in and of itself to retain in position a dressing that is interposed between the crotch panels and the body of the wearer, each garment section may have an elastic band 86, 88 secured at respective ends of the bands to inner surfaces of the garment adjacent inner ends of the crotch panels. These bands will aid in maintaining a fixed orientation of the dressing 70 and minimize any tendency of the dressing to move angularly about the tube 80 as an axis.
There has been disclosed an improved retainer and dressing for use with a medical instrument placed in a body opening that permits positioning and removal of the garment and the dressing without disturbing the instrument, but enables firm securement and self-centering of the garment upon the tube.
The foregoing detailed description is to be clearly understood as given by way of illustration and example only, the spirit and scope of this invention being limited solely by the appended claims.
