System and method for synchronously monitoring muscle tissue blood oxygen parameters and skin surface pressure

Abstract

The invention provides a system and a method for synchronously monitoring muscle tissue blood oxygen parameters and skin surface pressure. The system comprises a muscle oxygen level and pressure synchronous acquisition module for synchronously acquiring blood oxygen parameters of local muscle tissues of a human body and pressure values of skin surfaces of corresponding parts, a data analysis module which is used for receiving the human body local muscle tissue blood oxygen parameters and the pressure value of the skin surface of the corresponding part, transmitted from the muscle oxygen leveland pressure synchronous acquisition module, and analyzing the mapping relation between the local muscle tissue blood oxygen parameters and the pressure value, and setting a safety pressure thresholdvalue for maintaining normal microcirculation of muscular tissues at different parts of a human body, a pressure real-time monitoring module which is used for monitoring pressure values of all areas of contact interfaces of different parts of the human body and other objects in real time, and an alarm module which is used for giving an alarm prompt when the pressure real-time monitoring module detects that the pressure value is greater than the safety pressure threshold value. The interface design of an assistive device can be optimized, and skin problems such as pressure sores can be prevented.

Description

technical field [0001] The invention relates to the field of biological signal detection, in particular to a system and method for synchronously monitoring muscle tissue blood oxygen parameters and skin surface pressure. Background technique [0002] Some elderly people who have been bedridden or in wheelchairs for a long time due to limb motor dysfunction, and disabled people wearing artificial limbs, their buttocks, residual limbs and other parts have long-term contact with assistive devices such as beds, wheelchairs, and prosthetic sockets and are subject to greater pressure. Skin problems such as pressure sores, damage, and dermatitis are prone to occur at the contact parts of the skin and assistive devices. [0003] When designing assistive devices, optimizing the design of the assistive device interface to avoid excessive local pressure can prevent or reduce the occurrence of such problems to a certain extent. There have been some patent applications for pressure sore...

Problems solved by technology

[0004] However, due to the lack of monitoring of physiological parameters that reflect the state of skin and muscle tissue in the existing pressure sore protection technology, it is impossible to establish a quantitative relationship between pressure value and skin tissue damage, that is, it is not sure what pressure value will cause tissue microcirculation barriers, leading to the occurrence of skin problems
