Description

Dedicated bed for prone position after vitrectomy

technical field

The invention belongs to the field of medical instruments and equipment, and relates to a special bed for facilitating the recovery of patients after eye surgery, in particular to a special bed for prone position after vitrectomy.

Background technique

Vitrectomy combined with inert gas or silicone oil tamponade is one of the effective operations for the treatment of complicated retinal detachment. Its purpose is to push the injected gas or silicone oil from the vitreous cavity to the wall of the eyeball, and use the principle of upward floating of gas and liquid to directly press on the hole to block the flow of liquid at the hole and achieve the purpose of resetting the retina. The posterior hiatus is at the highest position, and patients often need to adopt a forced prone position. The maintenance of the passive position of the patient after the operation is related to the success of the operation. However, due to the long time in the prone position after the operation, the patient will have facial tenderness, backache, shoulder and neck pain and numbness and other discomfort symptoms, which will lead to insomnia, tension, anxiety, Scores for depression, frustration, anger, and hostility rose. In fact, after vitrectomy and gas injection, the patient can lead to pressure sores due to the long-term strict prone position.

Analysis of the status quo of prone position aids: U-shaped (or C-shaped) soft pillows and their improved products are the most widely used clinically, such as: horseshoe-shaped air pillows, U-shaped water pillows and improved U-shaped pillows, well-shaped head frames, etc. . Studies have shown that for patients in the prone position, the auxiliary use of such appliances increases air permeability compared with ordinary pillows, the force on the face is more uniform, the head is easier to fix, and the comfort is enhanced, thereby improving the success rate of the operation. To further enhance patient comfort, clinical nurses are continually improving assistive devices. Auxiliary devices such as special head support, multi-purpose support, eye hole bed combined with inflatable neck pusher and tractor have been developed successively. It has been found through practice that compared with U-shaped pillows, it can further improve air permeability and enhance comfort. better effect.

However, through long-term clinical use and repeated observations, it has been found that although appliances such as special head supports, multi-purpose supports and eyelet beds combined with inflatable neck pushers and tractors have significantly improved air permeability compared with U-shaped soft pillows, they are not conducive to the long-term development of patients. Maintain the correct body position at all times; in addition, the head support and inflatable neck pusher are easy to slide, especially after the patient falls asleep at night; , It is very easy to trip other patients in the same ward, and there are potential safety hazards.
