In my country, chronic non-communicable diseases have posed a serious threat to the health and life of people, especially the elderly. Chronic diseases and degenerative diseases require long-term follow-up and treatment, but it is impossible for a large number of patients to stay in the hospital for long-term treatment. The monitoring of pathological parameters is less effective and less accurate. In addition, most patients have the ability to move freely, but the current monitoring method makes the patients bound to the hospital and the hospital bed. Most of the monitoring methods used in hospitals use fixed medical monitors and connection equipment to connect the sensor probe between the patient and the monitoring equipment for signal transmission. Most of the effective human body signals for patient monitoring are in the natural state of the human body. measured in state. This traditional method of connecting detection equipment to the human body for monitoring will make patients feel unnatural and nervous, which will lead to inaccurate detected data.
