Example Embodiment

[0045] Example 1:

[0046] The TCM pulse collection device includes a pressure sensor array and an internal circuit. The location of the pressure sensor is as figure 1 Shown. Among them, the pressure sensor array element 101, the pressure sensor array element 102 and the pressure sensor array element 103 are arranged corresponding to the "inch", "off" and "ruler" pulse points of the human wrist, and are used to collect the "inch, off, and off" pulse points of the human wrist. This type of sensor can be called a pulse sensor; the pressure sensor array element 104 can be placed near the pulse sensor on the wrist, but it will not be pressed against the position of arteries and blood vessels, and is used to collect Incoming vibration and noise, this type of sensor can be called a noise sensor. In order to avoid errors caused by each pulse sensor array element not accurately corresponding to the pulse points of "inch", "off", and "ruler" when the traditional Chinese medicine pulse c...

Example Embodiment

[0076] Example 2:

[0077] The foregoing embodiment 1 is an example in which three pressure sensor array elements or arrays are used as pulse sensors, and one pressure sensor array element is used as a noise sensor. Taking into account the different physiological structures of the human body, each person’s blood vessel position and degree of curvature are different, and for the convenience of people who do not have any medical knowledge to use this product, the pressure sensor array elements that make up the pressure sensor array 401 in embodiment 2 are on the wrist The position of the position is not set in advance, that is, the positional relationship between the pressure sensor and the pulse point and the arterial blood vessel is not limited, but the signal collected by the pressure sensor is used to determine whether it is a pulse sensor or a noise sensor; the pressure sensor can be arranged as Image 6 The rectangular structure shown can also adopt other structures, as long a...

Example Embodiment

[0079] Example 3:

[0080] The following describes the implementation of determining the sensor type (whether the pulse is collected or the noise is collected) in Embodiments 1 and 2. Figure 7 Shows the step flow chart of the first judgment method. The process of this step is described as follows:

[0081] First, perform frequency domain conversion on all sensor data;

[0082] Secondly, perform spectrum analysis on the converted data to find the corresponding frequency with the strongest spectrum;

[0083] After that, according to the characteristics of the pulse spectrum, the pulse sensor and the noise sensor are distinguished. The frequency can be compared with the normal pulse range of the human body (normal heartbeat is 45 to 120 beats per minute). If it falls within this range, it is considered normal, otherwise it is considered that there is no pulse signal in the spectrum.

[0084] Figure 8 Shows the step flow chart of the second judgment method. The basic principle is that...

Abstract

The present invention belongs to the technical field of medical instruments, and specifically relates to a traditional Chinese medicine pulse manifestation acquisition apparatus. The apparatus comprises a sensor array, a multipath signal conditioning circuit, a multipath synchronous A/D circuit and a single chip microcomputer; the sensor array comprises pulse sensors and noise sensors, and the noise sensors are used for acquiring vibration noise data introduced by a body; the multipath signal conditioning circuit is used for filtering and amplifying signals acquired by the sensors; the multipath synchronous A/D circuit is used for synchronously acquiring the signals processed by the multipath signal conditioning circuit in real time and converting the signals into digital signals; and the single chip microcomputer is used for sending the converted digital signals into an intelligent terminal. The present invention also provides a noise reduction system and a noise reduction method. The pulse sensor data are corrected by utilization of noise sensor data, interference of vibration noise on a traditional Chinese medicine pulse manifestation instrument can be effectively reduced, and therefore repeatability and accuracy of pulse manifestation instrument diagnosis can be improved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a traditional Chinese medicine pulse condition collection device, a noise reduction system and a noise reduction method. Background technique [0002] TCM pulse monitor uses the theory of TCM pulse diagnosis, uses sensors to collect the pressure signal of the pulse point on the user's wrist at the "inch, off, and ruler", quantifies the pressure signal and analyzes it, and finally realizes the identification of the user's pulse characteristics, assists the doctor's diagnosis and the user's health management. [0003] The domestic research on TCM pulse condition instrument has a history of more than 30 years, and the theory of pulse condition analysis has been preliminarily formed. However, as a medical device, the TCM pulse monitor has not yet met high requirements in terms of repeatability and accuracy. One of the important reasons is that the pulse sign...
