Embodiment Construction

[0052] The pressure sore risk assessment method and system based on near-infrared spectrum muscle oxygen content measurement of the present invention will be described in detail below in conjunction with the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only illustrative illustrations of the present invention, and are not intended to limit it in any way.

[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0054] The present invention collects the muscle oxygen content of the subject by using the near-infrared spectrum muscle oxygen detection system, analyzes and processes the collected muscle oxygen signal by the wavelet transform method, and obtains the wavelet amplitude of the muscle oxygen signal in each frequency segment, thereby evaluating the test degree of muscular tissue damage.

Abstract

Provided is a pressure sore risk assessment method and system based on near-infrared spectrum muscle oxygen content measurement. The method includes the steps of (1) in a resting state, monitoring the muscle oxygen parameter content of a pressure sore risk area; (2) applying 10-30 kPa of pressure for 1-10 minutes to the pressure sore risk area; (3) after pressure interruption, measuring the muscle oxygen parameter content of the pressure sore area for 5-15 minutes; (4) processing the muscle oxygen parameter content signals collected by step (1) and (3) to show the risk probability of the occurrence of pressure sores. According to the pressure sore risk assessment method and system, the muscle oxygen content can be non-invasively detected, and the equipment has good portability, which facilitates real-time monitoring.

Description

technical field [0001] The invention relates to a pressure sore risk assessment method and system based on near-infrared spectrum muscle oxygen content measurement Background technique [0002] Pressure sore, also known as decubitus ulcer, refers to the degeneration and necrosis of tissue and cell ischemia, hypoxia, and nutritional metabolism disorders due to continuous pressure on local soft tissues. Pressure ulcers not only increase the pain and economic burden of patients, cause a waste of medical resources, but also affect the recovery of the disease. Once a pressure sore occurs, it will not only aggravate the condition, delay treatment, reduce the quality of life of the patient, increase the cost of treatment, but also cause serious infection and death of the patient. Prevention is the main means to avoid the occurrence of pressure ulcers, and actively evaluating the patient's condition through scientific means is the key first step in prevention. [0003] Research on...
