Description

Zigbee-based portable multifunctional health monitoring wristband and monitoring method

technical field

The invention relates to the technical field of portable online monitoring of human health status, in particular to a Zigbee-based portable multifunctional health monitoring wristband and a monitoring method.

Background technique

In recent years, heart disease is still one of the major diseases threatening human life, and the death rate of heart disease still ranks first in the world. According to statistics, about one-third of the death toll in the world is caused by such diseases, which has become the most common disease that endangers human health. Therefore, the prevention and diagnosis of heart system diseases is the primary problem facing the medical field today. ECG signal is one of the earliest biosignals studied and applied in clinical medicine. It is easier to detect than other bioelectrical signals and has a more intuitive regularity. Therefore, electrocardiogram analysis technology promotes the development of medicine. Electrocardiography is an important method for clinical diagnosis of cardiovascular diseases. Changes in heart rate are closely related to heart disease. If the heart rate exceeds 160 beats per minute, or is lower than 40 beats per minute, it is mostly seen in heart disease patients. If it is often accompanied by discomfort such as palpitations and chest tightness, a detailed examination should be carried out early in order to treat the cause.

Blood oxygen saturation is an important physiological parameter reflecting the respiratory and circulatory function, and blood oxygen saturation monitoring is becoming more and more common in clinical applications. It is widely used in cardiopulmonary critically ill patients, anesthesia patients, premature infants and newborns, in order to timely evaluate the state of blood oxygen saturation, and to detect patients with hypoxemia very early, so as to prevent or reduce hypoxia more effectively accidental death. The temperature of the human body is closely related to the ambient temperature, and both affect the health of the human body at the same time.

The results of the domestic research are that among the literature reports on the wireless sensor network for medical monitoring that have been seen, some of them are similar to the research content of this paper, but they use Bluetooth technology in wireless communication, and they are not based on wireless sensor networks. It is only a personal medical portable device designed for the collection of patients' physiological parameters at ordinary times, and does not have the function of wireless transmission. In addition, the interactive terminal of testing equipment on the market uses supporting display equipment, which is relatively expensive and generally suitable for special places such as hospitals.
