DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a device for stabilizing the pelvis of a lying patient in a preselected angular position relative to a conventional flat bed.
BACKGROUND OF THE INVENTION
Handicapped children with e.g. brain damage which occurred before, during or just after birth do not have full control over their body functions, and often have a limited ability to move and have some characteristic patterns of movement and resting positions. In particular the resting positions are often incorrect and in the long run cause thrust loads in the lumbar region, hip joint luxations and gradual damage to the ability to sit. Also, with elderly people, who are forced to stay in bed permanently or for long periods of time there are risks of damage of such type and also risks for bedsores.
There is already a device on the market, consisting of a rest, somewhat shorter than the patient, and mainly designed like a seat with a back rest. Belonging to this there is a cushion intended to be placed between the patient's legs and one or more straps to keep the patient lying on his side with his back turned to the back rest.
However, the known device has a number of disadvantages. It is comparatively big and it is cumbersome to turn the patient from one side to the other. The cushion intended for leg support is completely loose and easily moves into positions where it does not serve any purpose.
SUMMARY OF THE INVENTION
A purpose of this invention is to provide a device of such type which does not have these disadvantages. For example it preferably leaves some space for moving the extremities and provides support for the lumbar region of the patient on one side and on the other side for the patients hip bone, whereby the pelvis is stabilized at a right angle to the bed.
This is achieved according to the invention by providing a device which includes a body which from a general point of view is disc shaped with two basically parallel planar surfaces, is intended to be placed between the lower extremities of the patient and is designed with a cavity, which extends from one edge of the body toward its center and which conforms to and is somewhat bigger than the contour of the patient's pelvis as seen from the side. Projecting outwardly from the planar surface are protruding parts, preferably arranged in pairs on opposite sides of the body and arranged to keep the body up far enough from the bed so that there is room for one of the patients extremities between the bed and the planar surface facing the bed while the other extremity rests on the opposite planar surface, whereby there is a certain moving space for the extremities between the protruding parts and at the cavity the supporting surfaces are arranged to support the lumbar region of the patient on one and on the other side the hip bone of the patient.
According to a special characteristic of the invention the distance between said the planar surfaces is big enough for the lower extremities of the patient to rest mutually parallel and in line with the spine when using the device, one extremity on the bed and the other on the planar surface facing away from the bed. Thus the tension on the hip joint decreases, which gives relief to already injured hip joints and delays and possibly prevents hip joint luxation.
A according to another special characteristic of the invention at least one of the protruding parts serves as a support for the hip bones of the patient, is completely displaceable toward and away from the cavity and is detachable from the disc shaped body, so that device can be used while a young patient grows and the best possible lying position can always be achieved by adjusting the protruding parts.
According to a suitable design the protruding part or parts which support the back of the patient extend further out from the disc shaped body than the part which supports the hip bones of the patient in order to support the lumbar part of the patient.
It is desirable that such back parts are comparatively thin in a direction normal to the sur
