Method and device for sensing human pulse in traditional Chinese medicine

Abstract

The invention relates to a method and equipment for sensing human pulses in traditional Chinese medicine, and discloses pulse sensing equipment and a pulse sensing method for pulse sensing. In an embodiment, the equipment comprises robotic fingers, the robotic finger comprise humanoid finger structures and actuating force transmission parts, and the actuating force transmission parts are used for transmitting actuating force to actuating points on the humanoid finger structures along an actuating direction. One end of each of the humanoid finger structures can be mounted on a pivot in a pivoted manner, and a sensing area is arranged at the other end of each of the humanoid finger structures. Due to the structure of the each robotic finger, when the sensing area is in contact with a human wrist, a first vertical distance from the pivot to a first line is longer than a second vertical distance from the pivot to a second line, the first line is a straight line penetrating a sensing point of the sensing area and basically vertical to the sensing area, and the second line is a straight line penetrating the actuating point and positioned along the actuating direction.

Description

technical field [0001] The present invention generally relates to machine-based sensing of a human pulse in traditional Chinese medicine practice. In particular, the present invention relates to such machine-based sensing by means of a mechanical structure which has at least one advantage of eliminating disturbances of actuation forces during human pulse sensing. Background technique [0002] In recent years, pulse sensing has become available through devices. Machine-based human pulse sensing has certain advantages over pulse sensing by CMP. These advantages include efficiency as well as repeatability. In addition, a signal processor can be used to process the signal sensed by the pulse sensing device, so that an automatic medical diagnosis system can be realized. [0003] In a pulse sensing device, an actuator is usually employed to move and position a pulse sensing sensor to a person's wrist. Typically, as disclosed in CN101049247, TW20113233 and TW200727865, the actu...

Problems solved by technology

This noise fluctuation is directly superimposed on the sensor, so that the sensed human pulse signal is significantly corrupted by the noise fluctuation of the actuation force, where the sensor is usually a pressure sensor for pulse sensing

Although, one can reduce this noise fluctuation to a considerable extent by employing hydraulic actuators which can be configured to achieve a high degree of stability in the generated actuation force, the hydraulic actuators are bulky and difficult to maintain, and expensive
