Definitions

  • the present invention relates to urine management devices for babies, children or adults, to be adhesively attached in a releasable manner to the uro-genital area of the wearer, said devices being particularly easy to put in place and providing a largely improved performance in collecting urine.
  • Urine management devices are known articles of manufacture that are designed to be worn principally by incontinence sufferers and infants. Such urine management devices are attached to the uro-genital region of the wearer and are intended to entrap and immediately contain urine and other bodily discharges. As a consequence, these devices are functionally effective in lessening epidermal irritation; in preventing contamination of articles such as clothing and bedding; and even in preventing the soiling of the carers themselves.
  • the urine management devices are made from a plastic material.
  • GB 1,092,274 discloses a pediatric urine collector for female use comprising a collector bag of plastic material opening. The base of the opening is provided with a wedge like projection adapted to engage the lower perineal area of the infant. The collector is secured to the body of the wear by adhesive material.
  • GB 2,268,882 discloses a urostomy pouch/bag of plastic material provided with a circular stomal orifice which is surrounded by a first coupling member, by which the pouch can be affixed to a counterpart coupling member, which can be attached to a wearer.
  • the pouch may also be provided for use as a kit further comprising an applicator of super absorbent material which can be injected into the pouch by the use of a plunger.
  • US 4,804,377 discloses a collector for urine specimens from children. The collector comprises a rectangular flange for adhesive attachment, which comprises a round, slightly oval aperture.
  • EP 140 478 discloses a disposable diaper having a water proof barrier preferably polypropylene or polyethylene formed as a flattened bag having a single opening.
  • US 1 ,092,274 discloses a urine collector for female infants comprising an aperture which is smaller at the bottom end than at the top end and could be described as droplet shaped.
  • US 3,292,626 also discloses a urine collector for female infants comprising a circular or droplet shaped aperture.
  • Chinese patent application CN 1079381 discloses urine bags for infants with circular and elliptical apertures.
  • Another problem associated with urine management devices is their behaviour after unintentional detachment and their handling after detachment. Since they regularly are a source of malodour and possibly of leakage, the area of the aperture should not be chosen larger than necessary for good performance.
  • adhesive urine management devices can be designed which have excellent ease of placement properties, through the use of a simple, but efficient device.
  • the same design does not only greatly help in placing the device but also assists in handling after detachment.

  • the flange (12) comprises adhesive (20) used to attach the device (10) to the uro-genital area of the wearer.
  • the invention resides principally in providing an optimised shape of the aperture (21) of said device (10).
  • Preferred embodiments of the present invention regarding the contour of the aperture (21) are: a) a slit like contour, b) an oval contour oriented in said transversal direction, wherein said transversal diameter of the aperture (21) is at least 1.25 times greater than said longitudinal diameter, c) an oval contour oriented in said longitudinal direction, wherein said longitudinal diameter of the aperture (21) is at least 1.25 times greater than said transversal diameter, d) a cross shaped contour.

  • Such an aperture (21) is beneficial in particular with regard to male wearers. It has the advantage of providing a large diameter in the longitudinal and in the transversal direction while providing shorter diameters in the direction in-between. In these directions adhesive portions on the flange (12) can be provided close to the urinary duct.
  • the aperture (21) does not need to have any element of symmetry, however in a preferred embodiment the aperture (21) is symmetrical to the longitudinal axis, and in an even more preferred embodiment the aperture (21) is symmetrical to the longitudinal axis and to the transversal axis.
  • the symmetry of the aperture (21) to the longitudinal axis reflects the substantial symmetry of the human body to the longitudinal axis and thus is typically beneficial for the good anatomical fit of the urine management device (10), as well as for proper adhesion and complete collection of urine.
  • the symmetry of the aperture (21) to the transversal axis may allow the urine management device (10) to be placed to the uro-genital area of the wearer without ensuring a specific orientation regarding the perineal and coccygeal areas of a wearer. Said symmetries typically also allow the easier, cheaper and more accurate production of the flange (12) and may also ensure a more aesthetic appearance of the device (10).
  • All the embodiments described herein have an aperture (21) as small as possible with regard to the optimal performance of the device (10) for particular wearer groups and uses.
  • the risk of skin irritation due to contact of urine with the skin of the wearer is as far as possible reduced.
  • the apertures (21) described herein provide a large surface area of the flange (12) close to the centre of the aperture (21) while not hindering the urination process and thereby still allowing effective collection of urine.
  • the presence of such large areas of the flange (12) close to the centre of the aperture (21) is very beneficial, as it allows for a more secure attachment of the urine management device (10) by adhesive provided on the wearer facing portion (23) of the flange (12).
