Pressure injury monitoring and feedback device and feedback regulation system

Abstract

The invention relates to a pressure injury monitoring and feedback device and feedback regulation system, and belongs to the technical field of monitoring devices. Pressure acquisition assemblies and a transmission assembly are arranged in a flexible shell of the device; the pressure acquisition assemblies are connected with a control assembly; the pressure acquisition assemblies are used for acquiring contact pressure information of a target part; the transmission assembly is used for receiving and sending the contact pressure information; and the control assembly receives the contact pressure information of the target part, thereby calculating the internal stress, corresponding to the contact pressure information, of deep tissue, and an early warning is given out when a pressure injury threshold value of the target part is reached. According to the device, by measuring the contact pressure information of the external surface, the internal stress of the deep tissue corresponding to the contact pressure information is predicted, and monitoring of the pressure injury of the deep tissue is realized, so that the early warning is given out at the early stage of the pressure injury for intervention to effectively prevent the pressure injury, and the device is convenient and quick.

Description

Technical field[0001]The present invention belongs to the technical field of monitoring equipment, and more particularly to a pressure damage monitoring and feedback equipment and feedback adjustment system.Background technique[0002]Pressure Injury refers to limitations of skin and (or) skin and / or soft tissue under the intense and / or long-term pressure or pressure combined shear force causes the skin and / or soft tissue under the skin and (or) soft tissue. It often occurs in a part of the body surface, withstand weight or pressure, such as hip, buttocks, heels and elbows. The incidence of pressure damage is 1% to 56%, and the study shows that the average hospitalization time (20.9 days) of patients with pressure damage occurring (20.9 days) is much higher than that of patients with pressure damage (12.7 days). Medical costs about $ 11 billion. Pressure injury prolong patient hospitalization time, reducing the quality of life, increasing the risk of patient death, is a major pr...

Problems solved by technology

Some foreign scholars have developed an algorithm for deriving the internal strain of soft tissue from external pressure based on the reduced-order modeling technology, but this model does not use the geometric parameters specific to the human body, and the extent to which the internal strain of the soft tissue will cause irreversible damage to cells is still unknown. Not clear, in addition, no relevant literature has been found in China

At the same time, the existing pressure monitoring system has the disadvantages of unstable pressure monitoring, high cost, and unclear safety.
