Description

Bed board structure for relieving extrusion feeling

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a bed board structure for relieving extrusion feeling.

Background

Standing up is a common medical device, such as standing training of hemiplegia and cerebral apoplexy patients, and also can effectively prevent bedridden syndromes such as muscular atrophy, calcium loss, hypotension, joint contracture and the like by using the standing up bed for some patients who cannot stand for a long time.

When standing training is carried out by using a standing bed, a trainer often needs to be changed from lying posture to sitting posture or from lying posture to standing posture, most of the body is attached to the bed board of the standing bed when lying down, however, the following problems still exist when the posture is changed:

First, when the gesture of lying changes into the position of sitting, the backplate upwards rotates to the back plate above the seat and has taken up the space above the seat to make the length that the person's health contacted with the seat reduce, nevertheless because of the frictional force is great between person and the bed board, and the person of training is because of the health feedback function variation, is difficult to carry out self-regulation fast in the gesture change, leads to the person of training to have the sense of extrusion when gesture changes waist and buttock, thereby brings the discomfort, has reduced the patient and has adopted the willingness of standing up to carry out training.

Second, for patients with hemiplegia, paralysis or myasthenia, when the lying posture is changed into standing posture, the body of the trainer loses support and is easy to shrink downwards, the patient is bound by the binding belt, the shrinking process can not achieve the training purpose, and the fear psychology of the trainer is increased, so that the treatment is not facilitated.
