[0024] The core part of this system, as an optimal solution, is introduced as follows.
[0025] Part 1: Heart Rate Simulation Module
[0026] It is used to control the speed of the simulated heart rate beating.
[0027] The flow rate of the peristaltic pump 4 is adjustable to realize the adjustable frequency of the simulated heart rate.
[0028] A second stepper motor 41 is used to drive a peristaltic pump to pump at a dose of 2500 ml per minute to realize the beating of the radial artery.
[0029] Adopt adjustable resistive type as adjusting switch 2 (being prior art), described adjusting switch 2 is connected in series with control module 10, and described control module 10 is connected with second stepper motor 41, thereby adjusts the rotating speed of peristaltic pump, to adjust each The dose is pumped in minutes, and finally the heart rate is regulated.
[0030] Such as image 3 As shown, the structural design: the heart rate simulation module includes a peristaltic p...
