A real-time dynamic prevention and detection system for pressure injury based on pressure sensor

Abstract

The present invention relates to a method for real-time dynamic prevention and detection of pressure injury based on a pressure sensor. The method at least includes one or more of the following steps: acquiring pressure change data caused by a bedridden patient on a mattress; acquiring the The temperature and humidity change data of at least one pressurized part of the bedridden patient in contact with the mattress, the temperature and humidity change data is obtained based on the heat balance processing of the human body in a manner that is not close to human body perception, and / or the pressure change data is The first pressure sensor and the second pressure sensor with different pressure measurement methods are obtained by changing the working density on the mattress respectively, and the method further includes: based on the pressure change data and the temperature The pressure injury detection rule dynamically converted by the humidity change data is used to predict and analyze the pressured parts, so as to prevent the pressure injury of the bedridden patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a real-time dynamic prevention and detection system for pressure injury based on a pressure sensor. Background technique [0002] According to the definition of pressure injury published by the National Pressure Ulcer Advisory Panel (NPUAP): a pressure injury is a bony prominence, skin and / or under medical or other devices. or localized damage to soft tissue; may present as intact skin or open ulcers and may be painful; damage is due to intense and / or prolonged pressure or pressure combined with shearing forces. Soft tissue tolerance to pressure and shear may be affected by the microenvironment, nutrition, perfusion, comorbidities, and soft tissue conditions. Pressure injury is a common problem faced by health care institutions around the world. It not only brings great pain to patients and severely reduces their quality of life, but also increases medical costs and cons...

Problems solved by technology

[0006] Aiming at the problem of strong subjectivity and low trustworthiness in the current pressure injury assessment scale, in the prior art, such as the above-mentioned patent document with the publication number CN107496116A and the patent document with the publication number CN107496117A, it is proposed to assemble multiple Sensors are used to realize the monitoring and prevention of bed sores, including such as pressure sensors, temperature sensors, humidity sensors, etc., but at least have the following defects: First, due to the large area of ​​the mattress and the need to configure a large number of temperature and humidity sensors, the smart The cost of equipment increases, and the price of existing smart equipment products is tens of thousands; The use needs of bedridden patients with small humidity changes; in addition, the data collected by the temperature sensor and humidity sensor is large and complex and highly discrete, the data processing volume is large and complex, and the requirements for CPU and other hardware equipment are high. Leading to a further increase in the cost of smart devices
