DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a low friction bed sheet or the like to facilitate changing the position of a person or part of the person's body in a prone position and including at least a low friction surface (1) made of substantially frictionless material and a bordering high friction surface (2) of high friction material.
BACKGROUND OF THE INVENTION
It is well known that it can be very difficult for people with physical handicaps of different types to turn over in bed. This increases their suffering considerably. Examples of these types of people are those with permanent of temporary partial paralysis, people with different types of injuries, for example back injuries, people that have recently been operated on, etc. Today there is no good commercial aid to help people with these motor problems turn themselves over in bed.
In U.S. Pat. No. 3,849,813 a "draw sheet" is described, that is a sheet that is put under a person to help a carer turn the person in bed by pulling the "draw sheet" toward himself/herself. It includes a central inner part of an essentially frictionless material which has been attached to a normal sheet. This has been done to make it possible for the user who lies on the sheet to glide easily while his/her extremities, which are in contact with the normal sheet material, can achieve the change in body position.
The problem with the above draw sheet is that no account has been taken of the fact that the person in question can slip out of the bed, as attention has only been paid to assuring the position of the draw sheet's low friction part on the bed through sufficiently long side parts which are tucked in under the mattress. Another problem is the proposed material for the low friction part, which is either easily damaged when wet (for example rayon) or cannot be washed at sufficiently high temperatures, at least 70.degree. C. (for instance acetate), which is a requirement on bed and textile materials in hospitals.
There is another aid known as "Ross Glidmatta" which is sold in different sizes. The low friction mat is primarily an aid for carers to help them move or turn a physically handicapped or newly operated person in a mild way. The low friction mat is often used in combination with a normal draw sheet.
If a physically handicapped person uses the low friction mat above to help turn himself/herself in bed the low friction mat is clearly dangerous, especially when the person is to get into or out of the bed because high friction surfaces are absent. The low friction mat is also made of thick padded material which can seem clumsy and warm to lie on. For the above reasons the low friction mat is unsuitable for long term use in beds for physically handicapped persons.
In SE patent 8405630-8 the slipperiness problem has been observed, but the low friction bed sheets that are presented still have such important problems that in practice they cannot be used. In the choice of low friction material for the slippery part only friction and not washability, comfort or the risk of bedsores has been taken into account (silk or plastic are quite inappropriate). Because both surfaces of the low friction bed sheet have slippery surfaces, it can easily slip to the side when the patient lies on the bed or gets up from it.
Other often occurring problems for bedridden persons with physical handicaps or sicknesses are incontinence and the risk of bedsores. Modern hospital care, handicap care and elderly care lack a complete aid which facilitates position changes in bed in a safe manner from the point of view of accident risk and which at the same time functions as an incontinence protection and reduces the risk of bedsores.
THE PURPOSE OF THE INVENTION AND THE SOLUTION OF THE PROBLEM
The purpose of the present invention is to provide a low friction bed sheet of the type mentioned in the beginning which facilitates changing the position of a bedridden person, that is turning himself/herself over or changing his/her position in bed and gives the bedridden person an indication of when he/she nears
