Postoperative skin flap and reconstructed limb blood flow state detection epidermis attaching type sensing system

Abstract

The invention discloses a postoperative skin flap and reconstructed limb blood flow state detection epidermis attaching type sensing system, and belongs to the field of medical health monitoring. The system comprises a front-end state detection module and a rear-end signal processing output module, the front-end state detection module collects the blood oxygen saturation degree and the temperature state of a postoperative skin flap and a reconstructed limb in real time, a flexible packaging layer is adopted to package a printed circuit board, after the surface of the flexible packaging layer is chemically treated, a pre-polymerized hydrogel solution is injected for crosslinking to obtain a hydrogel adhesion layer, so that the hydrogel adhesion layer can be tightly attached to the skin for a long time, and meanwhile, bacterial infection on the skin surface is avoided; and the rear-end signal processing output module processes the oxyhemoglobin saturation and temperature data and sends the oxyhemoglobin saturation and temperature data to a mobile terminal in real time. According to the system, the postoperative skin flap and the blood flow health state of a reconstructed limb can be monitored on line, meanwhile, when the blood oxygen saturation degree of a human body is lower than a normal value or the body temperature and pulse signals are abnormal, the mobile terminal can trigger an alarm function to remind medical staff and patients in time.

Description

technical field [0001] The invention belongs to the field of medical health monitoring, and more specifically relates to a skin-attached sensor system for detecting the blood flow state of postoperative skin flaps and reconstructed limbs. Background technique [0002] According to the data provided by the American Cancer Society, in the past five years, there are about 252,710 new cases of breast cancer every year, and the total number of head and neck cancer patients exceeds 822,000. Among them, mastectomy is often used for the treatment of breast cancer, and head and neck cancer is often used for the treatment of head and neck cancer. For tumor ablation, reconstruction of the wound site is particularly important in consideration of the aesthetics of the patient's surgical site and reducing the probability of wound infection. Among them, skin flap transplantation greatly improves the reconstruction ability of skin tissue and effectively avoids postoperative infection. At th...

Problems solved by technology

These emerging testing instruments are of great significance for improving the success rate of flap transplantation and early warning of symptoms such as flap vascular injury and ischemia, but there are still certain limitations in the above measurement techniques, such as implantable detection, non-persistent Measurement, complex operation, high cost, large volume and other defects, so the development of a low-cost, wearable, non-invasive continuous detection of postoperative skin flaps and reconstruction of limb blood flow status skin-attached sensing system has broad application prospects
