Intelligent bedsore monitoring and preventing equipment with feedback secondary pressure self-adjustment

Abstract

The invention provides intelligent bedsore monitoring and preventing equipment I with feedback self-adjustment. A plurality of supporting units are evenly distributed under a mattress, a supporting column is connected with a supporting baffle through an universal connecting joint in each unit, and a pressure sensor for collecting the pressure of a patient on the mattress and integrating and transmitting the pressure to a monitoring and processing system is installed between each supporting baffle and the mattress; magnetic valves are adopted to control pressure adjusting piston cylinders to drive the supporting columns; an air pressure monitoring and adjusting container is connected with the pressure adjusting piston cylinders through the magnetic valves, and the air pressure in the container is controlled by the monitoring and processing system; a detecting air passage and an adjusting air passage are installed in the mattress, wherein the detecting air passage sucks air under the body of the patient under the action of an air pump and detects the temperature and humidity, and the adjusting air passage outputs dry low-temperature air onto the mattress under the action of an air pump. According to the equipment, body pressure quantized distribution conditions of the patient in different body positions and quantized changing conditions of the temperature and humidity of the skin micro-environment can be accurately continuously recognized and monitored, and the body surface pressure and the temperature and humidity of the skin can be fed back and adjusted.

Description

technical field [0001] The invention relates to a medical comprehensive intelligent device, which can accurately monitor the body surface pressure, temperature and humidity of a patient while lying in bed, and perform feedback adjustment, so as to eliminate the pathogenic factors of bed sores. Background technique [0002] Bed sores (also known as pressure sores, pressure ulcers) are due to long-term pressure on the local skin and subcutaneous tissue, resulting in damage to blood vessels and lymphatic vessels, continuous ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. Or the bony prominence where the muscle layer is thin, lacks adipose tissue protection and is often compressed (European Pressure Ulcer Advisory Panel [EPUAP], 1998). Inducing factors for bedsores include: 1) pressure factors, including vertical pressure (the most important factor), friction, and shear; 2) physical stimuli such as moisture; 3) general nutritional status; 4) age...

AI Technical Summary

Problems solved by technology

The pressure release method of non-electrically driven mattresses is passive, and the surface pressure is redistributed through the characteristics of the material itself, which depends on the immersion and wrapping capabilities of the material itself. If the material has strong compliance, the area of ​​immersion and wrapping of the contact object will be large, and the local The pressure is lower and can carry out more effective pressure distribution, so it has the disadvantages that it cannot be actively adjusted and the specific decompression effect is unknown.

Although electric-driven mattresses can actively adjust the contact surface for active pressure redistribution, this type of distribution is a blind surface pressure redistribution with a fixed program set manually. There is no quantitative objective basis for the specific pressure distribution method and specific unified specifications. Whether the effect is suitable for individual patients is even more impossible to monitor and learn

For the humidity and temperature of the local microenvironment of the patient's skin, there is no corresponding monitoring auxiliary equipment, and there is no corresponding specific quantitative evaluation index, basically relying on manual extensive regular inspection and nursing intervention, or ignoring this content.

Therefore, in the context of the current era of precision medicine, due to the many deficiencies in medical auxiliary equipment, the degree of automation and intelligence in the monitoring, prevention and treatment of bedsores is extremely low, and to a large extent still depends on a large amount of investment in manual medical care.
