Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a protective device for preventing pressure injuries. Background Art

[0002] In order to prevent long-term bedridden patients from receiving continuous pressure on their feet, which may lead to pressure injuries, medical staff usually use protective devices to prevent pressure injuries to protect the patients' feet. Existing protective devices to prevent pressure injuries usually consist of a fixing seat, a cushion and an elastic band.

[0003] For example: The utility model with application number CN202120573561.6 discloses a simple protective device for preventing pressure injuries. Specifically, the utility model discloses a simple protective device for preventing pressure injuries, which relates to the field of medical technology, including a main fixing clamp and an auxiliary clamp. The main fixing clamp is located directly in front of the auxiliary clamp. The main fixing assembly includes a main fixing clamp, a fixing patch, a limiting ring, a main embedding groove, a limiting pad and a main sealing plate. The simple protective device for preventing pressure injuries, through the main fixing clamp, the auxiliary clamp and the buffer pad, avoids long-term fixed position and causes pressure injuries to the human body. The whole process is simple to operate and has a better fixing effect. It is reasonably designed. Through the fixing patch, it can also play the effect of fixing the patient's position. The whole device fixes the patient's functional position. Through the effective turning position, the occurrence of pressure injuries caused by ineffective turning over is greatly reduced. Through the main fixing clamp, the auxiliary clamp, the buffer pad and the limiting ring, the air permeability can be improved, which not only avoids the phenomenon of skin allergies, but also increases the comfort of the patient.
