Description

Prevent pressing sore nursing mattress Technical Field The utility model relates to the field of medical auxiliary instruments, in particular to a pressure sore prevention nursing mattress. Background Patients who lie in bed for a long time and cannot autonomously change body positions can seriously influence the treatment of the patients if pressure injury occurs in the course of treatment of the patients lying in bed for a long time. The existing nursing beds are mostly in a lying position, the lying posture of a patient cannot be automatically changed, when the nursing beds meet the patients with inconvenient actions and incapability of automatically turning over and lying on the side, nursing staff are required to regularly help the patients to turn over and lie on the side and change the postures so as to prevent muscular atrophy of the patients and pressure injury caused by long-term lying in a fixed posture, the nursing beds are very inconvenient, and the nursing staff can turn over the patients with serious coma, fracture and obesity and heavy weight, so that huge workload is caused to the nursing staff.
