Description

Pressure sore prevention mattress capable of measuring and regulating pressure and temperature

Technical Field

The utility model discloses measurable quantity and regulation and control pressure and temperature prevent pressure sore mattress relates to medical instrument technical field, is medical and nursing the mattress particularly, especially relates to a prevent the inflatable mattress of the measurable quantity and the regulation and control pressure and temperature of living pressure sore.

Background

Pressure injury, called pressure sore for short, is the tissue damage and necrosis caused by continuous ischemia and anoxia due to long-term compression of local tissues of a body and blood circulation disturbance. External pressure is the most dominant factor in the development of pressure sores, the development and extent of which depends on the strength and duration of the pressure. In order to solve the problem, the main preventive measures comprise the regular change of the body position and the application of pressure relief devices (mattresses, soft pillows) and the like, the nursing staff needs to put more energy to do related nursing work and the regular change of the body position increases the medical care workload, and the patient cannot carry out the operation for a long time and the influence of certain diseases and the patient who does not allow the change of the body position, and the patient is forced to keep one body position for a long time. At the moment, the pressure-relief mattress is applied more, but the pressure sore can not be completely avoided, the incidence rate of the pressure injury of inpatients in China reaches 4.7-18.6%, and the incidence rate of the pressure injury of patients admitted by nursing homes is 30%. Therefore, the pressure condition of the pressed part is accurately measured and improved through pressure regulation, and the pressure regulating device has great significance for avoiding pressure sores.

In recent years, attention has been paid to the correlation between the micro-environment state of the skin and the occurrence of pressure sores, in the framework of pressure injuries, the micro-environment generally refers to the skin temperature and humidity/moisture at the interface of the skin and the supporting surface, the skin temperature at the pressure injury part can be lowered due to the rise of inflammatory reaction or ischemia, and the influence of the rise or reduction of body temperature on the tissue tolerance has certain difference. The continuous compression of the tissue results in ischemia, hypoxia and insufficient nutrient supply, and the high metabolic demand caused by the rise of body temperature can greatly increase the susceptibility to crush injury. Accurate measurement and maintenance of the normal temperature of the pressed part are one of effective measures for controlling the microenvironment of the skin and preventing crush injury.
