When the intelligent mobile terminal is used, the video module of the intelligent mobile terminal is matched, the control lever 441 is manually adjusted to quickly position, then fine adjustment is performed through the sensors 4341 positioned under the simulated skin 433, and finally the pulse position is determined.

The pulse condition bionic component 43 comprises a supporting plate 435, a bionic blood vessel 431 arranged at the upper part of the supporting plate 435, and a sensor integrated circuit board 434 which is arranged at the lower part of the supporting plate 435 and provided with a sensor 4341 matched with the film cavity 4311, the pulse condition bionic component 43 is provided with a bionic skin 433 protruding on the upper cover 42, three mutually independent film cavities 4311 are formed between the bionic blood vessel 431 and a limit groove 4351 of the supporting plate 435, and the simulated heart pump A is communicated with a hose connection 4312 of the film cavities 4311 through a hose 432.
Bionic blood circulation System
The bionic blood circulation system comprises three sets of mutually non-interfering circulation units for the cun-guan ruler parts respectively, and pulse condition information of the cun-guan ruler can be independently simulated, and each circulation unit comprises a simulated heart pump A and a pulse condition bionic component 43 which are separated by an elastic liquid storage tank 47. The pulse-pattern bionic assembly 43 comprises independent chambers which are spaced from each other and correspond to the number of circulating units, and the simulated heart pump A rhythmically floods fluid into the pulse-pattern bionic assembly 43 through pulse current from the signal amplifier 48 and returns to the simulated heart pump A through the elastic fluid storage tank 47, thereby forming fluid circulation.
The simulated heart pump a is inserted into the circulatory system through the compartment 125, and the pulsed current drives the heave of the floating frame 23 and thus the motion of the compartment 125. When the compartment 125 contracts, i.e., corresponds to ejection of blood from the heart, three separate sets of simulated heart pump systems flush fluid into the membrane chamber 4311 of the bionic component 43 and ultimately react on the bionic skin 43; when the compartment 125 is gradually changed from the contracted state to the relaxed state, blood flow is pumped back into the compartment 125 from the flexible reservoir 47, and the fluid in the membrane chamber 4311 is also pumped into the flexible reservoir 47 due to the slightly negative pressure of the flexible reservoir 47. By additionally arranging the elastic liquid storage tank 47 between the liquid discharge end of the film cavity 4311 and the liquid inlet end of the compartment 125, the elasticity of blood vessels in the body can be effectively simulated, and the simulation degree is improved. In actual product debugging, after the pipeline position is completely fixed, the pipeline elasticity is kept unchanged, and the simulation of the whole circulatory system can be adjusted by adjusting the elasticity of the elastic liquid storage tank 47 when the vascular elasticity is repeatedly simulated. In particular, a rigid housing is provided for the stable engagement of the two ends of the fluid inlet and outlet, and an elastic membrane is provided on the housing to adjust the "elasticity" or "cushioning" of the elastic fluid reservoir 47.

The liquid inlet end 111 and the liquid outlet end 112 are externally provided with disc-shaped bulges, so that the connection of fluid pipelines is facilitated.
The valve body assembly 2 comprises an outer shell 26 matched with the valve cover main body 12 and provided with a heat dissipation hole 263, a bottom cover 27 for closing the bottom of the outer shell 26, a magnetic yoke 25 fixed at the bottom of the outer shell 26, a permanent magnet 24 fixed at the middle shaft of the magnetic yoke 25, a floating frame 23 floating and limited on the permanent magnet 24, a coil framework 22 floating and limited in an annular cavity 251 and fixed at the bottom of the floating frame 23, the cross section of the floating frame 23 is cross-like, the cross section is fixed on the middle shaft of the diaphragm 21 through a support disc 235 through a bracket middle hole 231, a bottom bulge 234 is just matched with the hollow structure of the coil framework 22, a limiting rod 232 is just matched with the middle hole of the permanent magnet 24, and an outgoing line 221 of the coil 222 is led out of the outer shell 26 through the heat dissipation hole 263.

In the above embodiment, the outer housing 26 and the bottom cover 27 are in a split structure, so that the prototype adjustment of the parts is facilitated, and the split structure can be realized by injection molding as an integral structure in mass production.
In use, the fluid and tubing uses environmental parameters similar to those of the blood circulation system by communicating the compartment 125 with the fluid circulation system (not shown) via the fluid inlet 111 and fluid outlet 112. In particular, the fluid resistance mainly comes from friction force of the inner wall of the pipeline, the volume of the blood vessel and carrier resistance of fluid solutes (electrolytes in blood), so as to simplify parameters and restore the actual blood circulation system as much as possible, and simultaneously avoid waste of blood resources. The electrolyte solution with the density similar to that of arterial blood is adopted.
According to ampere's law, the current in the coil 222 on the coil 222 skeleton 22 generates magnetic induction lines opposite to the direction of the permanent magnet 24, so that the coil 222 skeleton 22 floats along the permanent magnet 24, and the coil 222 skeleton 22 drives the diaphragm 21 to float up and down through the floating frame 23. When the number of coils 222 is fixed, the total weight of other structures is unchanged, and the magnetic induction linear density generated by the permanent magnet 24 is directly proportional to the input current, namely the repulsive force generated by the electromagnet formed by the coil framework 22 and the coils 222 is positively related to the input current. When the repulsive force just counteracts the current when the self resistance (mainly gravity) is taken as the standard current, the bionic blood in the compartment 125 flows out from the liquid discharge end 112 when the diaphragm 21 floats upwards, and the bionic blood is pumped into the compartment 125 when the diaphragm 21 sinks so as to simulate the pulse state. On the basis, corresponding current is generated according to the electric pulse signal sent by the user side, so that rhythmic pulsation of human body pulse can be simulated.
In the above embodiments, the vertical use of the heart pump is simulated, and the compartment 125 is closed, so that the electromagnet is hardly affected by the placement mode, and the resistance to be overcome by the repulsive force is mainly friction force when the horizontal type heart pump is used in comparison with the vertical type heart pump.
