Pressure relieving medical device suitable for the prophylaxis of pressure sores.

摘要

57 A device for the prophylaxis of pressure sores comprising a liquid retained within a flexible elastomeric envelope is described. The body contacting surface of the device is a film which has a moisture vapour transmission rate of greater than 300g/m<Sup>2</Sup>/24 hr at 37° C at 100 % to 10 % relative humidity difference. The liquid is a viscous liquid which absorbs moisture vapour. The device may be formed in the shape of the letter «U» which makes the device particularly useful for application to the sacrum. A device in which the liquid retained within the flexible envelope is a mixture of a viscous liquid and a hygroscopic material is also described. In a preferred form the body contacting surface carries a layer of adhesive whereby the device may be adhered to the patient in use.
