Pulse condition acquisition device

Abstract

The invention discloses a pulse condition acquisition device, comprising a sensor assembly. The sensor assembly includes a motor fixed on a housing, a screw rod which is fixedly connected with the motor, a lifting structure which is sleeved outside the screw rod, and a sensor detector head which is fixed at the bottom of the lifting structure. The screw rod is driven to rotate when the motor is rotating, so as to make the lifting structure move up and down relative to the screw rod. Based on the device, the invention provides a pulse condition acquisition method, comprising the following steps: (1) the motor rotation drives the lifting structure to ascend to the initial position; (2) the motor rotation drives the lifting structure to descend for a set distance, and judge is made on whether the lifting structure reaches the extreme position or not; if the lifting structure reaches the extreme position, the measurement is stopped; if the lifting structure does not reach the extreme position, the sensor detector head collects pressure signals; (3) the step (2) is repeated, and judge is made on whether pressure signals currently collected are stronger than those previously collected; if not, the measurement is stopped. The invention can realize automatic acquisition of pulse signals, and a limit protection structure is provided during the acquisition process.

Description

technical field [0001] The invention relates to a traditional Chinese medicine diagnosis device, in particular to a pulse condition collection device. The invention also relates to a pulse condition collection method. Background technique [0002] The diagnostic methods commonly used in Chinese medicine include looking, smelling, asking, and feeling. Among them, pulse diagnosis is one of the important diagnostic methods of Chinese medicine. In traditional Chinese medicine, finger pulse detection relies on tactile, pressure, and vibration receptors to detect pulse information under the condition that the fingertips exert different pressures on the radial artery (ie, floating, medium, and sinking pressures). It includes information such as solstice, rhythm, ups and downs, strength, thickness, hardness, softness, fluency, and difficulty. Therefore, the TCM pulse signal should be understood as a collection of pulse cutting pressure and pulse wave power. [0003] In the existi...

Problems solved by technology

[0003] In the existing human body pulse condition detection device, usually adopt the manual pressurization mode, for example, a kind of intelligent Chinese medicine pulse condition detection device (see figure 1 ), the defect of the above device is that it is impossible to accurately find the best measurement position, and the position of collecting signals cannot be repeated

[0004] With the development of technology, people have also begun to use automatic pressure measurement methods, but the set pressure method is usually controlled by a program or computer, and the limit protection structure is not used on the hardware. In this way, when the program fails, the sensor detects Keeping the head pressed against the person's pulse can cause damage
