Definitions

  • the present invention relates to a urine receptacle and apparatus for the automated disposal of bodily fluid. More particularly, the present invention relates to a reusable, disposable urine receptacle and apparatus for automated disposal of urine, which together provide the wearer increased mobility, comfort, discretion, and ease of use.
  • An exemplary bag is constructed of two pieces of identically sized and shaped plastic film that is sealed in such a manner as to create a rectangular, flat vessel with an inlet valve at the top and an outlet valve at the bottom. The valves are sealed in place between the two layers of plastic film.
  • slits are made at the four corners of the bag to permit the insertion, of an adjustable strap (both top and bottom). This strap is usually made of latex rubber or some similar material to which a plastic "button" has been attached.
  • Holes on the strap permit the user to adjust the tension of the strap by stretching the appropriate hole over the button, thus establishing a fixed degree of tension corresponding to the circumference of the leg to which the bag is attached.
  • the bag when it is filled with urine it expands to form a rectangular balloon with the surface area of the bag in contact with the leg decreasing steadily in proportion to the volume of liquid contained within the bag.
  • the bag expands in such a manner as to press against the clothing raising the clothing well above the surface of the skin. This tends to make the bag obvious to others, which can be embarrassing to the user.
  • the force holding the bag in place shifts almost exclusively to the straps, which accentuates the pressure already exerted by the buttons against the user's skin, to cause sores.
  • inlet tubes also hinder the flow of urine by causing misalignment between the bag and the catheter that carries the urine.
  • the placement of inlet tubes on existing bags is along the central axis of the bag such that placement of the bag on the user's thigh causes the inlet tubes to point away from the point at which the catheter is inserted or attached to the user.
  • the resulting misalignment often causes the catheter to become constricted as a result of a very small radius bend that forms where the catheter enters the inlet tube. This constriction, like the aforementioned side wall sticking and valve impingement, can interfere with and sometimes block the flow of urine into the bag, which leads to serious health consequences.
  • WO 87/05493 discloses a device for collecting urine and other fluids that comprises an inner elastic container enclosed by a rigid outer container.
  • the inner container is neither self supporting nor . designed for regular disposal.
  • the outer container is bulky so that it does not comfortably fit under clothing, and it does not conform to the wearer's body.
  • United States patent no. 4,511 ,358 discloses a urine bag carrier with a stretchable front panel pouch.
  • the bag is not self-supporting and must be removed from the relatively inaccessible pouch. Because the front panel exerts a compression force, it is moreover uncomfortable. Pius, the bag bulges in the middle, even despite the compression of the front panel pouch.
  • United States patent no. 4,533,354 discloses a medical drainage bag and non-return valve assembly.
  • the bag bulges in the middle, and as a result is uncomfortable and unseemly.
  • United States patent no. 4,386,930 discloses a collection device for body fluids with antiseptic pump. It has a relatively rigid inner receptacle that partially separates only a small portion of the inner walls of the outer receptacle, which can create messy and potential dangerous urine back flow.
  • the outer container is bulky and is not designed to be worn. Hence, it does not comfortably fit under clothing, and it does not conform to a wearer's body.

  • Tray 15 is made of polyolefin, poly vinyl chloride or polyethylene. Any material suitable for constructing a self-supportive tray that expands to a preformed dimension can be used, however. Because of the design approach taken, bag 1 can be made of a light-gauge material, and its overall size is reduced since no provision need be made for the attachment of straps. These factors permit a less expensive bag, which in turn permits the bag to be fully disposable on a daily basis.
