When the intelligent mobile terminal is used, the joystick 441 is manually adjusted to be quickly positioned by matching with a video module of the intelligent mobile terminal, then fine adjustment is carried out through a plurality of sensors 4341 positioned under the simulated skin 433, and finally the pulse position is determined.
The bionic blood circulation system comprises a simulated heart pump A, a pulse condition bionic assembly 43 forming circulation with the simulated heart pump A, and an elastic liquid storage tank 47 positioned between the simulated heart pump A and the pulse condition bionic assembly 43. The pulse bionic assembly 43 comprises a supporting plate 435, a bionic blood vessel 431 positioned on the upper part of the supporting plate 435, and a sensor integrated circuit board 434 positioned on the lower part of the supporting plate 435 and provided with a sensor 4341 matched with a film cavity 4311, wherein the pulse bionic assembly 43 is provided with a bionic skin 433 protruding out of an upper cover 42, three independent film cavities 4311 are formed between the bionic blood vessel 431 and a limiting groove 4351 of the supporting plate 435, and the simulated heart pump A is communicated with a hose connection 4312 of the film cavity 4311 through a hose 432.
Bionic blood circulation system
The bionic blood circulation system comprises three sets of circulation units which are respectively used for cun-guan positions and do not interfere with each other, pulse condition information of cun-guan positions can be simulated independently, and the circulation units comprise a simulated heart pump A and a pulse condition bionic component 43 which are separated by an elastic liquid storage tank 47. The pulse condition bionic assembly 43 comprises independent chambers which are spaced with intervals corresponding to the number of circulating units, and the simulated heart pump A periodically surges fluid into the pulse condition bionic assembly 43 through the pulse current from the signal amplifier 48 and returns to the simulated heart pump A through the elastic liquid storage tank 47, so that fluid circulation is formed.
The simulated heart pump A is inserted into the circulatory system through the compartment 125, and the pulse current drives the fluctuation of the floating frame 23 to drive the action of the compartment 125. When the compartment 125 is contracted, which is equivalent to the ejection of blood from the heart, the three independent sets of simulated heart pump systems flush fluid into the membrane chamber 4311 of the biomimetic assembly 43 and eventually react on the biomimetic skin 43; as the compartment 125 transitions gradually from the contracted state to the relaxed state, blood flow is re-pumped from the flexible reservoir 47 into the compartment 125, also pumping fluid within the membrane chamber 4311 into the flexible reservoir 47 due to the slight 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 a human body can be effectively simulated, and the simulation degree is improved. In the actual product debugging, after the position of the pipeline is completely fixed, the elasticity of the pipeline 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 elasticity of the blood vessel is repeatedly simulated. In the concrete structure, a hard shell is arranged for stably connecting the liquid inlet pipe and the liquid outlet pipe at two ends, and an elastic film is arranged on the shell to adjust the elasticity or the buffering property of the elastic liquid storage tank 47.

The liquid inlet end 111 and the liquid outlet end 112 are externally provided with disc-shaped bulges so as to be convenient for connecting with a fluid line.
The valve body assembly 2 comprises an outer shell 26 which is matched with the valve cover main body 12 and provided with a heat radiation 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 center 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 the annular cavity 251 and fixed at the bottom of the floating frame 23, wherein the cross section of the floating frame 23 is in a cross shape, the floating frame is fixed on the center shaft of the diaphragm 21 through a support disc 235 through a support center hole 231, a bottom bulge 234 of the floating frame is just matched with the hollow structure of the coil framework 22, a limiting rod 232 of the floating frame is just matched with the center hole of the permanent magnet 24, and a leading-out wire 221 of the coil 222 is led out of the outer shell 26 through the heat radiation hole 263.

In the above embodiment, the outer casing 26 and the bottom cover 27 are of a split structure, which is convenient for prototype adjustment of parts, and when mass production is performed, they can be realized by injection molding as an integral structure.
In use, compartment 125 is connected to a fluid circulation system (not shown) via inlet 111 and outlet 112, the fluid and tubing being subject to environmental parameters similar to those of the blood circulation system. Specifically, the fluid resistance mainly comes from the friction of the inner wall of the pipeline, the volume of the blood vessel, and the carrier resistance of the fluid solute (electrolyte in blood), so as to simplify the parameters and restore the actual blood circulation system as much as possible, and simultaneously avoid the waste of blood resources. The electrolyte solution with the density similar to that of the arterial blood is adopted.
According to ampere's law, current in the coil 222 on the coil 222 framework 22 generates magnetic induction lines in the opposite direction of the permanent magnet 24, so that the coil 222 framework 22 floats along the permanent magnet 24, and the coil 222 framework 22 drives the membrane 21 to float up and down through the floating frame 23. When the number of the coils 222 is fixed, the total weight of other structures is not changed, the magnetic induction linear density generated by the permanent magnet 24 is in direct proportion to the input current, that is, the repulsive force generated by the electromagnet formed by the coil framework 22 and the coils 222 is in positive correlation with the input current. When the repulsion force just offsets the current of the self resistance (mainly gravity) 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 of the pulse. Then based on the above, the corresponding current is generated according to the electric pulse signal sent by the user terminal, so as to simulate the rhythmic pulse of the human body pulse.
The above embodiments have been described using the vertical type of the heart pump as an example, and since the compartment 125 is closed, the electromagnet is hardly affected by the placement, and compared to the vertical type, the resistance force to be overcome by the repulsive force is mainly friction force when the horizontal type is adopted.
