Description

B11909 IX. Description of the Invention: [Technical Field] The present invention relates to a microphysiological signal collecting device, and more particularly to a patch type wireless microphysiological signal collecting device. [Prior Art] Heartbeat, brainwave, respiration, body temperature and other signals are indicators of signs of life. Medical institutions, security centers and various types of care are indispensable. If it is easier to obtain information about these physiological signals, it will help all kinds of care to be carried out. In addition to saving labor costs, it can improve the quality of medical care, and even can be extended to personal care. Therefore, the acquisition of micro-physiological signals is related. Has always been an important direction of medical development. Figure 1 illustrates an electrocardiogram (ECG) signal. In general, the most advanced band is called a QRS wave, where the point of the first upward deflection is the Q point, the top point is the r point, and finally the bottom. The end is called the S point. In the QRS identification process, the QRS wave in the microphysiological signal is first found by the spike detection program, and the parameters such as height (ampHtude) and duration (duration) are measured from each QRS wave, and the average of each parameter is obtained. And standard deviation calculation, used as a standard template. Each QRS wave is then compared against this template. Heart rate variability (HRV) analysis is a method for analyzing cardiac physiological function from a series of heartbeat cycles. The standard analysis procedure has been defined by the European and American Heart Association in 1996 (Task F〇rce 〇f the European Society of Cardiology and The North American Society of Pacing and Electrophysiology, 1996), after some modifications to the 106661 invention patent specification. d〇c 13 Γ 1909 (Kuo et al., 1999), the general principles are as follows: 1. First get the information of the heartbeat cycle, its large Part of the practice is to define the occurrence of each heartbeat from the R wave of the electrocardiogram, and the time difference between each R wave and the latter R wave is a heartbeat period RR. 2. If there is a large change in the continuous RR series, for example, more than three standard deviations, it may be a heart rate irregularity or noise. If it is the former, it should be mentioned immediately
The warning is that the life of the subject may be threatened by salt; if the latter, the techniques of measurement and analysis should be improved to overcome it. 3. If there are no large changes in the continuous RR series, these scales can be analyzed in more detail, including spectrum analysis (Ku〇 d al 1999) and nonlinear analysis (Kuo & Yang, 2002). Sleep staging is mainly dependent on brain waves, myoelectric waves, and eye movements. If you can easily perform sleep staging, you will have the opportunity to understand the occurrence and prevention of many sleep-related diseases. Simple brainwave measurements can be used to understand the occurrence of many diseases, such as epilepsy, Alzheimer's disease, etc. If you add a measurement of respiratory signals, you can further understand whether there are sleep-related respiratory diseases, such as sleep-disordered breathing. In addition, if you add heart rate or heart rate variability analysis, you can further understand the correlation between sleep and hypertension. Sleep physiological signal monitoring and analysis will be an indispensable physiological signal for clinical medicine. The popularization of this signal measurement will help many diseases. Prevention, monitoring and diagnosis of diseases. Respiratory rate is often used as one of the indicators of life in clinical practice. The faster the breathing, the faster the metabolic rate in the body, which is usually due to critical, stressful, and ill conditions. The respiratory rate signal is easily measured by a thermometer, that is, the temperature is measured by exhaling gas through the nostrils, and is a heart rate variability and blood pressure. 106661 invention patent specification. d〇c Ϊ311909 variation). Respiratory corrected heart rate variability can be more accurately assessed (Chen et ai,, body temperature is often used as one of the indicators of life in the clinic, the higher the body temperature, the faster the in vivo firing rate, usually because Faced with sickness. The measurement of the frontal temperature is a common and convenient indicator for body/dish measurement. Continuous monitoring will help to understand the changes in the condition, reduce the labor related to the medical care, and reduce the possibility of infection and infection. Φ Most of the The physiological signal collection system requires more than one wire. Although the signal can be accurate, it is necessary to connect a lot of wires to the subject, and it can not be tampering when it is tested. Therefore, not only the wiring is time-consuming, but also the inconvenience of the subject. It is impossible for the sensory to move freely. In recent years, with the advancement of technology, the technology of semiconductor and wireless transmission has been developed, and the products of miniaturized physiological signals have been implemented to realize the so-called "ambulatory" physiological signals. The collecting device can be about the size of a palm, and some can continuously store physiological signals in internal memory, and some can even receive physiological signals in time. The number is transmitted to the remote receiver by Φ radio waves or infrared rays, so that the outside world can know the physical condition of the tester in time. These techniques make the application of detecting physiological signals more convenient and flexible. However, the volume of these instruments is still too large. Big, the weight is too heavy, especially the way of wiring is still too complicated for the untrained. Although these wires are already very short, it will cause some inconvenience to the user. So the current physiological signals of these portable types are collected. The instrument basically belongs to the medical instrument, and it needs the expert to guide it to wear it properly. It is still not a consumable electronic product that the average person can use freely. The person wants to spread the physiological signal analysis technology more widely to each 106661 invention patent specification. D〇c 1311909 Families and individuals must overcome the inconveniences of various types of fixed or portable physiological instruments. Miniaturization and thorough wirelessization will be an inevitable development direction.
