[0034] Figure 1A structural schematic diagram of an embodiment of the present invention is shown, specifically showing the structure of this embodiment. This embodiment relates to a control device for a central liquid supply system, which uniformly controls the electric control valves connected to each hemodialysis machine through a PLC controller, and controls the opening and closing of the electric control valves to realize the unified liquid supply of the central liquid supply system to each hemodialysis machine and realize the self-circulation disinfection of each hemodialysis machine.

[0035] An application method of a medical systemized device based on PLC control, such as Figure 1 and Figure 2 As shown, the central liquid supply system 2 is connected to each hemodialysis machine 3, and an electronic control device is provided between each hemodialysis machine 3 and the central liquid supply system 2. The circulation and disconnection of the medical liquid supply are realized by adjusting the opening and closing of the valve port by the electronic control device. When the electronic control device controls the valve port to open, the central liquid supply system 2 provides medical liquid supply to each hemodialysis machine 3. When the electronic control device controls the valve port to close, the medical liquid supply provided by the central liquid supply system 2 cannot reach each hemodialysis machine 3. At this time, the hemodialysis machine 3 can realize internal circulation to complete self-circulation disinfection.

[0036] The method steps adopted in the embodiment of the present invention are as follows:

[0037] Set up a PLC controller and install an information processor at the location of the electronic control device;

[0038] The information processor is connected to the PLC controller and the electric control device;

[0039] The PLC controller can transmit information to the information processor, which can analyze and process the information for controlling the electronic control device; the information processor can also receive electrical signals from the electronic control device, and after processing, transmit the information to the PLC controller to display the information content.

[0040] Preferably, the electric control device in this embodiment includes an electric control valve 6 and an adapter 7. The adapter 7 in this embodiment is as follows: Figure 4 and Figure 5 As shown, it includes a first connecting pipe 9, a second connecting pipe 10, a third connecting pipe 11, a first connecting port 12 and a second connecting port 13, wherein a connecting port is provided at the inclined position of one end of the first connecting pipe 9, and the connecting port includes a first connecting port 12 and a second connecting port 13, wherein the first connecting port 12 is connected to one end of the second connecting pipe 10, and the second connecting port 13 is connected to one end of the third connecting pipe 11; the opposite end of the first connecting pipe 9 connected to the second connecting pipe 10 and the third connecting pipe 11 is connected to the electric control valve 6; the flow in the pipes of the second connecting pipe 10, the third connecting pipe 11 and one end of the first connecting pipe 9 is U-shaped and unobstructed, so that the pipes are kept unobstructed.

[0041] In the present embodiment, the electric control valve 6 is configured as a three-way ball valve, one end of the first connecting pipe 9 connected to the electric control valve 6 is connected to the central liquid supply system 2, and the second connecting pipe 10 and the third connecting pipe 11 are connected to the hemodialysis machine 3. When the electric control valve 6 closes the valve at the pipe mouth of the first connecting pipe 9, the medical liquid supply of the central liquid supply system 2 cannot flow from the connecting pipe 4 into the first connecting pipe 9 and then into the hemodialysis machine 3. At this time, the liquid suction end and the liquid return end of the hemodialysis machine are respectively connected to the second connecting pipe 10 and the third connecting pipe 11. Since the pipes are unobstructed, the self-circulation disinfection of the hemodialysis machine 3 is achieved. After the hemodialysis machine 3 completes the self-circulation disinfection, the valve of the electric control valve 6 is opened, so that the medical liquid supply of the central liquid supply system 2 flows into the first connecting pipe 9 through the connecting pipe 4, and flows into the liquid return end of the hemodialysis machine through the second connecting pipe 10. The medical liquid supply flows out from the liquid suction end of the hemodialysis machine to the third connecting pipe 11, and flows out from the third connecting pipe 11, so that the medical liquid supply is continuously circulated and replenished in each hemodialysis machine.

[0042] Preferably, the PLC controller 1 includes an information processor 5, such as Figure 3 As shown, the information processor 5 includes a processor, a controller and an alarm sensor 8. The information processor 5 is arranged around the electric control valve 6, and is electrically connected to the electric control valve 6 and the PLC controller 1 respectively. The processor can receive the electric signal of the PLC controller 1, and transmit the processed electric signal to the controller. The controller can adjust the valve mouth rotation direction of the electric control valve 6 to realize the control of the electric control valve 6 through the PLC controller 1; at the same time, the rotation amplitude information and rotation direction information of the electric control valve 6 are transmitted to the controller through the electric signal, and the controller transmits the electric signal to the processor for analysis, and transmits the electric signal to the PLC controller 1 through the processor, so as to realize the real-time control of the electric control valve 6 by the PLC controller 1.

[0043] Preferably, the PLC controller 1 is provided with a control panel, which includes a display screen and control buttons. The receiving information and transmission information of each information processor 5 can be displayed on the display screen, and real-time control of the electric control valve 6 can be completed through the control buttons, so that the electric control valve 6 can be remotely and uniformly controlled to realize the unified liquid supply of the central liquid supply system 2 to the hemodialysis machine 3. At the same time, the electric control valve 6 can be closed to enable the hemodialysis machine 3 to complete self-circulation disinfection.

[0044] Preferably, each information processor 5 is connected to the PLC controller 1 in parallel, and the control case of the control panel of the PLC controller 1 can control the mode switching of each or each group of information processors 5. A single information processor 5 can be controlled according to the different time when patients go on and off the machine in the hospital. At the same time, the disinfection of the hemodialysis machine for special patients who need to be used separately can be controlled separately.

[0045] Preferably, the information processor 5 also includes an alarm sensor, which can sense the valve port steering condition of the electric three-way ball valve. If it does not meet the setting requirements of the PLC controller 1, the electrical signal can be transmitted to the PLC controller 1, and a light prompt or sound prompt can be implemented through the control panel to avoid medical accidents, and at the same time, single-unit monitoring can be implemented for each hemodialysis machine.

[0046] The advantages and positive effects of the present invention are as follows: due to the adoption of the above technical scheme, unified delivery of the central liquid supply system is realized, each control valve is monitored in real time through the PLC controller, the liquid supply mode of the central liquid supply system is adjusted, and remote unified control or single-unit control can be completed for each hemodialysis machine. Different hemodialysis machine modes are used for patients with different medical conditions, which greatly reduces the work efficiency of medical staff and greatly improves the precise management of medical equipment.

[0047] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
