Description

 Physiological signal detector  

A physiological signal detector, in particular, a physiological signal detector capable of detecting physiological signals and calculating blood pressure and pulse wave velocity information.

In recent years, chronic diseases such as heart disease, diabetes, hypertension, and arteriosclerosis have prevailed. Although patients with these diseases have no obvious symptoms, they still suddenly deteriorate. The risk, if the patient does not receive immediate emergency care, then the patient may lose consciousness and lose the ability to breathe spontaneously within a few seconds. Therefore, how to immediately detect the physiological signals for patients with chronic diseases and provide emergency ambulance services is awaiting Solving the problem; the more common method used in the past is to measure the pulse transit time (PTT), that is, the pulse wave starts from the left ventricle (the electrocardiogram (ECG) R peak represents the ventricle extruding blood, that is, the pulse The time when the wave starts from the ventricle, the conduction velocity of the electrocardiogram in the body is the speed of light), the time of transmission to the end of the limb (by tonometry, impedance or photo plethysmograph, Observe the pulse wave and take the peak, which is the time when the pulse wave reaches the extremity. The pulse wave transit time matches the subject's own Flow kinetic parameters (eg, vascular elasticity, blood viscosity, etc., see US Pat. No. 5,865,755 A) can be used to estimate continuous non-invasive blood pressure, but these hemodynamic parameters are not easy to measure directly, so in practice The traditional cuff-type non-invasive blood pressure meter (NIBP) and the pulse wave transit time method simultaneously measure blood pressure, and compare the two to obtain the relevant hemodynamic parameters as a correction. Benchmarks, after which a continuous non-invasive blood pressure can be estimated using pulse wave transit time over a period of time (eg, two hours). However, after a longer period of time, hemodynamic parameters may be urinated or ventilated by the body. Temperature and humidity and other factors have changed significantly. At this time, it is necessary to calibrate with a traditional non-invasive sphygmomanometer to maintain accuracy. In order to allow users to perform continuous blood pressure measurement during normal life, it is not possible. Restricted by sphygmomanometers, non-invasive continuous blood pressure meters are best worn on the body, such as a series of US patents from Sotera Wireless (eg US 8,475,370) B2 and US 8,364,250 B2) disclose a technique which involves attaching three electrodes to the chest to obtain the R peak of the electrocardiogram signal (ie, the moment when the pulse wave starts from the ventricle), passing the wire over the left shoulder and then the host attached to the left arm. Then, the peak of the pulse wave of the photovascular volume (representing the moment when the pulse wave is transmitted to the thumb) is obtained by the light-emitting diode and the light sensor worn on the left hand thumb, and the time of both is transmitted (that is, the pulse wave is transmitted) Time) Estimate continuous non-invasive blood pressure. This patent has a traditional non-invasive sphygmomanometer attached to the upper arm for calibration. It can be removed after calibration to prevent the user from being restrained or uncomfortable. However, the technology involves The sensor is attached to a specific location to obtain an electrocardiogram, which is not only uncomfortable but also technically difficult for the average person to be operated by a medical staff. A sensor is disclosed in U.S. Patent No. 7,481,772 B2 to the entire disclosure of U.S. Pat. There are two electrodes on the patch to capture the R peak of the electrocardiogram, and a light-emitting diode and a photodiode to capture the pulse volume of the photovascular volume, and estimate the continuous non-period Incorporating blood pressure, the advantages and disadvantages of this sensor architecture are similar to those of US 8,369,936 B2, the R-peak signal is small and susceptible to interference, and the electrode is very uncomfortable on the body; U.S. Patent Publication No. US 2008/0,221,461 to Triage Wireless discloses A blood pressure measuring method, which uses a two-electrode to take an electrocardiogram and uses two optical or pressure type blood vessel volume sensors to obtain a pulse wave signal, and calculates a pulse wave transit time, and two The pulse wave signal is used for differential and other calculations in order to obtain blood pressure, but it must be worn on the same limb with two vascular volume sensors, which is not comfortable; US Patent Publication No. US 2014/0,249,398 discloses a calculation using a mobile phone. The method for measuring the pulse wave transit time, wherein the electrocardiogram signal is obtained by the two electrodes of the device on the mobile phone, and the pulse wave signal is obtained from the pupil by the camera on the mobile phone, and the time of the two is used as the pulse wave transit time. U.S. Patent No. 7,896,811 B2 to the disclosure of U.S. Pat. The sensor simultaneously obtains the electrocardiogram and the pulse wave. However, when the user holds the device, the two hands cannot perform other work at the same time; in summary, the prior art mostly connects the electrocardiogram electrode and the blood vessel volume sensor in the same device. However, it is necessary to lengthen the wire on the body, sacrificing the indispensable comfort of the wearable system, which is difficult for the user to accept. The current technology has not been able to provide a comfortable and easy-to-operate wearable pulse wave conduction time. A device for the long-term use of diagnosed or high-risk patients with hypertension or stroke to obtain physiological information in an immediate and continuous manner.

In view of the above problems, the present inventors conducted research and analysis on the physiological signal measurement device of the human body based on the experience of the industry and product design related to physiological signal measurement for many years, and can detect the physiological signal of the human body. Therefore, the main object of the present invention is to provide a physiological signal detector that measures physiological signals through a sensor and calculates blood vessel age, blood pressure, and pulse wave velocity information, and is convenient to use.

In order to achieve the above object, the present invention mainly comprises a first outer casing and a second outer casing, wherein the outer casing can be clamped to the wrist of the user, and the bottom of the first outer casing is provided with two senses. a sensor, and the two sensors can be attached to the two different positions on the wrist of the user after being clamped to detect a first physiological signal and a second physiological signal, and then pass through an information processing module. The group processes and analyzes the detected two physiological signals to calculate physiological information such as blood pressure, blood vessel age, and pulse wave velocity (PWV) of the subject.
