Intelligent bedsore monitoring and preventing equipment with feedback self-adjustment

Abstract

The invention provides intelligent bedsore monitoring and preventing equipment with feedback self-adjustment. The equipment comprises a mattress and a monitoring and processing system, and according to the mattress, the upper and lower sides of polyurethane foam sponge are coated with polyurethane fiber protective surface layers respectively; a plurality of pressure sensors for collecting the pressure of a patient on the mattress and integrating and transmitting the pressure to the monitoring and processing system are evenly distributed on the upper surface of the polyurethane foam sponge; a detecting air passage and an adjusting air passage are installed in the polyurethane foam sponge; the detecting air passage sucks air in the lying position of the patient, the temperature and humidity are detected and transmitted to the monitoring and processing system by a temperature and humidity sensor, and dry low-temperature air is output to the portion, in the lying position of the patient, of the upper surface of the mattress by the adjusting air passage 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 temperature and humidity of the skin micro-environment 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...

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...
