Description

Retina postoperative rehabilitation bed

Technical Field

The invention relates to the technical field of medical instruments, in particular to a retina postoperative rehabilitation bed.

Background

The retina vision part is often called retina for short, is a soft and transparent film, is tightly attached to the inner surface of choroid, and has the function of sensing light stimulation; the retina of human eyes is divided into a nerve epithelial layer and a pigment epithelial layer, and when liquid enters and accumulates between the two layers of tissues, the nerve epithelial layer leaves the original anatomical position, namely, the retina falls off; retinal detachment is a serious fundus disease, which can cause serious consequences such as blindness and eyeball atrophy if not treated in time, and can seriously affect vision once the retinal detachment occurs.

In the retinal detachment operation, gas or silicone oil is injected into the vitreous body to press the retina, and the density of the gas and the density of the silicone oil are both less than that of the vitreous body, so the gas or the silicone oil can float above the vitreous body and press the retina upwards, and the retina can be attached and reset, which causes that a patient needs to keep a posture facing the underlying body all the time after the operation, and the face needs to be kept downwards even during sleep; generally, medical staff can require a patient to sleep and rest by adopting the traditional prone sitting posture of a headrest on the arm, the sleeping posture can cause the cervical vertebra and the lumbar vertebra of the patient to be over-bent, the deformation of the vertebra and the strain of muscles at the neck and the waist can be easily caused, and the vertebra diseases are caused; and the arms and the buttocks of the patient can be pressed by larger pressure for a long time, so that the blood vessel cavity of the pressed part is narrowed or even disappears, the local blood circulation is disturbed, and the irreversible pressure injury such as local soft tissue ulceration, necrosis and the like can be caused even by continuous ischemia, anoxia, malnutrition and the like.
