DESCRIPTION:
BRIEF SUMMARY
This invention relates to the amelioration of the seating conditions to which a patient suffering from urine incontinence is subject and relates more particularly to a barrier cushion for this purpose and to urine removal systems comprising the same.
While it may not be possible to prevent urine incontinence, amelioration of the conditions to which a patient suffering from urine incontinence is subject is commonly achieved by seating a patient on an absorbant pad, frequently termed an incontinence pad, which is formed of wadding material on an impervious plastics film base and which is for taking up fluid passed by the patient. Such incontinence pads are however inefficient. They have only a limited capacity and become saturated, giving rise to a number of undesirable features. Apart from the basic discomfort to the patient of being in contact with cold urine, by virtue of the chemical content of urine, the wet or saturated pad inflames bed sores, retards their treatment, soils personal clothing and bedding and requires their frequent changing.
Alternatives to such simple incontinence pads which aim to remove from the immediate vicinity of the patient urine and/or faeces are proposed in a number of documents. These use a variety of approaches. Thus, for example, a conventional bed mattress has to be modified to receive a urine and/or faeces collecting device in U.S. Pat. Nos. 1,341,564, 1,395,879, 1,916,039, 4,096,596 and 4,368,733 and French Pat. No. 479,265, a drain system being proposed in each of these documents with the exception of U.S. Pat. No. 1,395,879. The principle of U.S. Pat. No. 4,096,596 is also applied to a chair. Such systems are relatively expensive to provide in requiring replacement of a conventional mattress on a bed by such specially modified mattresses and generally only provide the required urine/faeces removal facility at a single location which may not always be suited to the size of patient and his positioning in a bed.
An improved underpad for a patient which can be laid on a conventional mattress or seat is described in U.S. Pat. No. 4,173,046 which, while purporting to maintain a relatively dry top surface through its ability to store substantial volumes of liquid in an absorbent layer below a top cushioning layer, is still a disposable item which cannot be reused and is considerably more expensive to produce than the simple conventional incontinence pad.
It is an object of this invention to provide a reusable barrier cushion for use in instances of incontinence with either male or female patients which does not result in the patient sitting or lying in contact with urine and which does not require permanent modification of a mattress or seat.
According to the present invention, there is provided a barrier cushion construction for positioning below a patient suffering from incontinence and which is to communicate with storage means below a patient, which cushion is formed as a resilient body having an upper surface plane substantially parallel to its lower surface planes when unstressed, the upper surface plane being interrupted by an inclined drainage plane extending downwardly from a forward marginal region of the resilient body to a drain hole in an interior region thereof communicating the lowermost region of the inclined drainage plane with the lower surface plane of the resilient body, at least the inclined drainage plane and interior wall of the drain hole having urine-impermeable sheet material at its surface. Preferably, a urine-impermeable sheet material is located over the entire surface area of the resilient body including the interior wall of the drain hole which, thus lined, remains open for throughflow of urine for removal, for example as described hereinafter. The resilient body may be a plastics foam block having a continuous surface skin providing such sheet material. However it is preferred that such sheet material be a plastics film which envelopes the resilient body. Although it is preferred to form the resilient body as a foam block, it may be a cushion w
