Background

Retinal detachment refers to separation of retinal nerve epithelium and pigment epithelium, and is a major cause of vision deterioration, and is also a clinically common blinding eye disease. Currently, combined with silicone oil or inert gas filling by vitrectomy is the most effective method of treating retinal detachment with a reduction rate of up to 90%. The operation is to reset retina by using the principle that silicone oil or gas injected into vitreous cavity floats up through density, so that the patient is required to keep passive body positions such as head low position for a long time after operation, the split hole is in high position, and the resetting rate of retina detachment is improved. The patient needs to keep the head low with the face down for 18-20 hours daily for 2-4 weeks.

Most of the existing limiting devices used after the retinal detachment operation are U-shaped pillows or U-shaped pillow-like pillows, and the size of the headrest is generally fixed and does not fit the face of a human body, so that the size of the headrest cannot be flexibly adjusted according to the needs of different patients. The patient is prone to keep the head low on the headrest, and the headrest needs to be placed or simply fixed on a nursing bed or a wood frame and other fixtures when in use, so that the patient also needs to depend on the fixtures for a long time when in use, the movement range of the patient is severely limited, and various physiological needs of the patient cannot be met. And the patient is in passive position for a long time, can cause patient's comfort level to obviously decline, leads to patient's postoperative position compliance to decline, and the patient is difficult to persist for a long time and keeps the head low level, can unconscious raise the head, and the U-shaped pillow can't effectively restrict patient's head and remove to make the treatment position change, influence treatment effect, extension recovered speed.
