[0002] Solenoid valve is a kind of industrial equipment controlled by electromagnetism, is used to control the automation basic element of fluid, belongs to control element, is used to control actuator. It is used to adjust the direction, flow, speed and other parameters of medium in industrial control system. Its working principle is to control the mechanical movement of valve core by controlling the on-off of electromagnetic current, to close and start different air holes, to achieve the purpose of controlling some parameters of fluid into mechanical element. Solenoid valve group is a kind of integrated control element that integrates multiple solenoid valves on busbar.

[0003] Peritoneal dialysis machine is the medical instrument used in the process of filling dialysate into the abdominal cavity of patient, using peritoneum to complete dialysis, and then leading fluid out of abdominal cavity. In existing peritoneal dialysis machine, solenoid valve group is the core component of liquid path control, responsible for accurately adjusting the flow direction, flow and pressure of dialysate, directly affecting the safety and effectiveness of treatment. In traditional solenoid valve group, it is mostly composed of a group of solenoid valves and an integrated busbar, and the internal air path of the busbar is processed and combined by punching straight holes from the outer wall to the inside, so in some unused hole positions, steel balls need to be installed with interference fit for sealing. When peritoneal dialysis machine is used, high-frequency on-off operation is required, and the above-mentioned steel ball sealing structure is easily subject to high-pressure gas impact and corrosion for a long time, which may cause sealing failure.

The integrated busbar with multilayer air path structure is usually large as a whole, which is not conducive to the miniaturization and portable design of equipment, especially when used in household peritoneal dialysis equipment.

[0038] When using the dedicated solenoid valve assembly for the clamp-on peritoneal dialysis machine in this embodiment, X1 connecting hole 311 is connected to XAEG, X2 connecting hole 310 is connected to XVS1, X3 connecting hole 38 is connected to XP1, X4 connecting hole 31 is connected to XHIPOS, X5 connecting hole 36 is connected to XLPOS, X6 connecting hole 34 is connected to XVS2, X7 connecting hole 32 is connected to XP2, P3 connecting hole 39 is connected to PA1, P4 connecting hole 37 is connected to the positive pressure gas cylinder, P6 connecting hole 33 is connected to PA2, P8 connecting hole 35 is connected to the negative pressure gas cylinder, the load interface 312 connected to the outlet of solenoid valve 1 of V7 is connected to the high positive pressure door airbag, the load interface 312 connected to the outlet of solenoid valve 1 of V19 is connected to the blocking door airbag, the load interface 312 connected to the outlet of solenoid valve 1 of V18 is connected to the suction end of the air pump, and the load interface 312 connected to the outlet of solenoid valve 1 of V20 is connected to the outlet end of the air pump.

[0039] When the solenoid valve assembly is energized, the inlet (port 2 in the gas path diagram) and outlet (port 3 in the gas path diagram) of all solenoid valves 1 are connected; the gas in the air pump passes through solenoid valve 1 (V20), enters the positive pressure gas path 21, flows through solenoid valves 1 (V5, V6, V8), and then through solenoid valves 1 (V5, E, E, V1, V8, A, V1) to the negative pressure gas path 22, and finally returns to the air pump through solenoid valve 1 (V18), forming a loop; at this time, the path... ①: Blocking door airbag, V19 solenoid valve 1, positive pressure air path 21; ②: V13-V17 and V21-V26 solenoid valves 1, negative pressure air path 22; ③: V2 solenoid valve 1, V3 solenoid valve 1, V1 solenoid valve 1, negative pressure air path 22; ④: V11 solenoid valve 1, V10 solenoid valve 1, V12 solenoid valve 1, negative pressure air path 22; ⑤: V7 solenoid valve 1, high positive pressure door airbag, all are in the intake state, that is, the high positive pressure door airbag is inflated and bulging, and the blocking door airbag is deflated and concave.

[0041] The solenoid valve assembly repeats the above process, sequentially turning on and off the power, causing the blocking valve airbag and the high positive pressure valve airbag to alternately draw in and release air, thereby enabling the membrane dialysis machine to perform dialysis.

[0042] The positive pressure cylinder is used to maintain the air pressure of the high positive pressure air path 21. When the air pressure is too high, the positive pressure cylinder draws in air, and when the air pressure is too low, the positive pressure cylinder releases air, so that the air pressure of the high positive pressure air path 21 is maintained within the set range. The negative pressure cylinder is used to maintain the air pressure of the negative pressure air path 22. When the air pressure is too high, the negative pressure cylinder draws in air, and when the air pressure is too low, the negative pressure cylinder releases air, so that the air pressure of the negative pressure air path 22 is maintained within the set range.
