Embodiment 1

[0046] The TCM pulse acquisition 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 respectively arranged corresponding to the "inch", "off" and "ruler" pulse points at the wrist of the human body, and are used to collect the pulse points of "inch", "off" and "ruler" at the wrist of the human body. 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 on the position of the arterial blood vessel, for collecting Incoming vibration 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 "foot" when the traditional Chinese medicin...

Embodiment 2

[0077] The above-mentioned embodiment 1 is an example in which three pressure sensor elements or arrays are used as pulse sensors, and one pressure sensor element is used as a noise sensor. Considering that the physiological structure of the human body is different, each person's blood vessel position and curvature are different, and for the convenience of people without any medical knowledge can use this product, the pressure sensor array elements that make up the pressure sensor array 401 in Embodiment 2 are placed on the wrist The position of the position is not set in advance, that is, the positional relationship between each 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 judge whether it belongs to the pulse sensor or the noise sensor; the pressure sensor can be arranged as Figure 6 The rectangular structure shown can also adopt other structures, as long as it is ensured that som...

Embodiment 3

[0080] The implementation of judging the sensor type (whether the pulse is collected or the noise collected) in Embodiments 1 and 2 will be described below. Figure 7 A flow chart of the steps of the first judgment method is shown. The flow of this step is described as follows:

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

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

[0083] Afterwards, 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 45-120 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 frequency spectrum.

[0084] Figure 8 A flow chart of the steps of the second judging manner is shown. The basic princ...

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...
