Non-fixation wristband type pulse collecting system and method

Abstract

The invention provides a non-fixation wristband type pulse collecting system and method. The collecting system comprises an optical sampling wristband and an intelligent terminal, the optical sampling wristband is worn by a tested object and does not need to be tightly attached to the skin of the wrist of the tested object, light emitted by the inner side face of the optical sampling wristband is reflected by the skin, then received by the inner side face of the optical sampling wristband and converted into optical data corresponding to the reflected light of the skin of the wrist to be recorded, the wristband transmits the optical data corresponding to the reflected light of the skin of the wrist to the intelligent terminal to be analyzed and processed, and the intelligent terminal utilizes the optical data corresponding to the reflected light of the skin of the wrist within a continuous period, so that real-time pulse signals of the tested object are obtained. The wristband and the intelligent terminal can be carried about, according to the system, pulses are sampled through optical signals, the pulse signals can still be obtained in the moving process of the tested object, and therefore the system has good portability and real-time performance. In addition, the system can encrypt the optical data and is good in safety because only the specific intelligent terminal can obtain the pulse signals of the tested object.

Description

technical field [0001] The invention relates to the field of mobile medical care, in particular to a non-fixed bracelet-type pulse collection system and a collection method. Background technique [0002] With the advancement of modern medical methods and the rapid development of mobile medical care, portable physiological signal acquisition equipment has become a research hotspot, and among them, the pulse signal with rich physiological information has undoubtedly become the focus of attention. At present, most of the pulse signal acquisition equipment is based on the principle of pressure and photoplethysmography, and these two methods require the device to be in close contact with the pulse acquisition part of the human body (contact type), and the interference of the human body movement is particularly large, making it impossible to detect The pulse signal of the measured object in a non-stationary state; this limitation greatly limits its application in mobile medicine. ...

At present, most of the pulse signal acquisition equipment is based on the principle of pressure and photoplethysmography, and these two methods require the device to be in close contact with the pulse acquisition part of the human body (contact type), and the interference of the human body movement is particularly large, making it impossible to detect The pulse signal of the measured object in a non-stationary state; this limitation greatly limits its application in mobile medical

[0003] To solve the problem of pulse signal acquisition in portable and arbitrary states of the measured object (including static or arbitrary motion state), the pulse collection system must be able to overcome the motion interference of the measured object, while the traditional devices based on piezoelectric and photoplethysmography Neither can solve the problem; at the same time, traditional devices based on piezoelectric and photoplethysmography must be closely attached to the detection part of the measured object, that is, they are all fixed contact detection devices, so it brings great inconvenience to pulse detection. At present, there is no non-contact, non-fixed, portable pulse signal acquisition system and acquisition method that can overcome the motion interference of the measured object.
