Problems solved by technology

After the pressure sensor of the pulse diagnosis instrument has developed from a single point to a multi-point matrix, the signal has a spatial form of expression. If the pressure sensing surface and the wrist position to be measured are not in an ideal vertical relationship, the signal waveform is prone to tilt or offset, which is not ideal. Facilitate the analysis and processing of signal data

Embodiment 1

[0026] Such as Figure 1-5 As shown, the mechanical finger used for the pulse diagnosis instrument in the embodiment of the present invention is mainly composed of a fixed column 10, a sensor fixed plate 20, a pressure sensor module 90 and a driving device, wherein the fixed column 10 extends vertically, and the fixed column The upper end of 10 is a fixed end 11, and the lower end is a free end 12. The fixed end 11 of the fixed column 10 is connected with the finger drive mechanism (not shown in the figure) of the pulse diagnosis instrument, and the fixed column 10 is driven up and down by the finger drive mechanism, thereby driving the whole mechanical finger to move up and down. The free end 12 of the fixing column 10 is provided with a second groove 13 with the opening facing downwards, and a second support hole 16 is respectively arranged on two side walls of the second groove 13 .

[0027] The sensor fixing plate 20 is connected to the free end 12 of the fixing column 10...

Embodiment 2

[0041] The structure of the mechanical finger for the pulse diagnosis instrument in this embodiment is substantially the same as that of the mechanical finger for the pulse diagnosis instrument in Embodiment 1, except that: the first drive mechanism 70 and the second The two drive mechanisms 80 are located on the same side of the upper fixing plate 40, which can reduce the width of the fingers so that three same fingers can be used side by side.

[0042] To sum up, the mechanical finger for pulse diagnosis instrument of the present invention has the following advantages:

[0043] 1. The pressure sensing surface of the pressure sensor has two degrees of freedom of rotation, and the two rotation angles of the pressure sensing surface can be actively controlled by the driving device, so as to adjust the rotation angle along and perpendicular to the blood vessel when collecting the pulse phase. In order to get more accurate pulse signal.

[0044] 2. The axis of the first cross ax...

Abstract

The invention discloses a mechanical finger used for a pulse analyzer. The mechanical finger includes a fixation column, a sensor fixation plate, a pressure sensor and a drive device, wherein one endof the fixation column is a fixation end, the other end of the fixation column is a free end, the sensor fixation plate is provided with a sensor installation surface and connected with the free end of the fixation column through a first cross-shaped shaft, and the sensor fixation plate has two rotational freedom degrees and can rotate around a first virtual axis and rotate around a second virtualaxis intersected with the first virtual axis, the pressure sensor is installed on the sensor installation surface, and the drive device is used for driving the sensor fixation plate to rotate aroundthe first cross-shaped shaft. According to the mechanical finger used for the pulse analyzer, the sensor installation surface can oscillate around the axis of a rotating shaft, the pressure sensing surface of the pressure sensor can oscillate in two degrees of freedom, when the human skin makes contact with the pressure sensing surface, a pressure signal can be obtained, and the drive device controls the pressure sensing surface to be adjusted to a reasonable angle according to the pressure signal, so that a more accurate pulse signal is obtained.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a mechanical finger for a pulse diagnosis instrument. Background technique [0002] Pulse diagnosis, as a diagnostic method of traditional Chinese medicine in my country, has gradually formed a diagnostic system of 28 pulse conditions after thousands of years of research and practice in traditional Chinese medicine. At present, the main way of TCM pulse diagnosis is still that TCM physicians perceive the patient's pulse condition through their fingers, and then diagnose diseases based on the physician's experience and tactile sense of hands. The judgment standard of this diagnostic method is vague, and it is easy to be misjudged by the personal experience and subjective factors of the physician, and it is impossible to quantify and effectively record the pulse condition. [0003] For this reason, a pulse-diagnosing instrument for pulse diagnosis has appeared on the market. This pu...
