Problems solved by technology
[0002] As we all know, some of the existing pulse test sensors use the piezoelectric film principle, which can only measure the pulse rate; some use the ceramic piezoresistive principle, which can measure the pulse rate and blood pressure waveform.
Looking at all related inventions of the same kind at present, the sensors that use a single sensor head to measure the pulse beating blood pressure wave cannot eliminate the error caused by the deviation of the test angle and test position.
The pulse sensor is a precision instrument, and the accuracy of the measured pulse pressure signal is very high, and small deviations will also cause adverse effects on the interpretation results.
Therefore, when the existing products are used, large errors are likely to occur due to the deviation of the loading point and the loading angle of the force, so it is indeed necessary to design a new product
[0003] Some of the existing pulse test sensors use the piezoelectric film principle, which can only measure the pulse rate; some use the ceramic piezoresistive principle, which can measure the pulse rate and blood pressure waveform
Looking at all related similar invention products at present, it is impossible to use two completely independent output sensors to simultaneously detect the pulse beating and blood pressure wave intensity at the same point. The redundant design is used to ensure the reliability of the test, and the sensor can be adjusted mechanically. It has the function of overload protection by itself, so that the sensor can avoid damage as much as possible during the application process
Therefore, when the existing products are in use, they will easily be damaged and lead to system paralysis or overload and cannot be used, so there is a need for new product design

Embodiment 1
[0024] Such as Figure 1 to Figure 3 Shown is a schematic diagram of the structure of the present invention, the redundant output mechanical overload protection anti-overload pulse pulse blood pressure wave intensity sensor includes two contact probes 10, and three shells 21, 22 and 23 cooperate together to assemble and fix a spring 30 , a locator 40, a four-beam elastic body 50; four pairs of double-resistance silicon strain gauges 61-62, 63-64, 65-66, 67-68 are pasted on the four beams 501-504 of the elastic body, and a resistor The connection board 70, a temperature compensation and amplification circuit board 80 and output leads 100 are formed.
[0025] When the touch probe 10 transmits force to the four-beam elastic body 50, as Figure 4 , the beams 501-504 can all produce linear elastic deformation at the same time, and the deformation drives the resistance value of the silicon strain resistance 61-68 pasted on it to change linearly (such as Figure 5 ), using four res...
