[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Please refer to the attached Figure 1-Figure 7 The embodiment of the present application provides a blood treatment device, which is used to treat the blood drawn out of the human body and then transport the treated blood back to the human body. Specifically, it can be a hemodialysis device or a blood purification device. The blood treatment device includes a device body and an operation display. The device body is provided with a pump group 60, a sensor assembly and a circuit board assembly. The pump group 60 includes a plurality of booster pumps 61, such as a pump for inputting dialysate into a treatment component such as a dialyzer or a separator, a pump for transporting waste liquid, a pump for transporting blood, etc. The sensor assembly includes a plurality of sensors, such as a weighing sensor, a bubble monitoring sensor, a blood leakage sensor, etc. The circuit board assembly includes a power board 22 and an integrated central control board 21, and an interactive processing board located in the operation display; wherein the power board 22 is connected to the power box 70, and is connected to the central control board 21 and the interactive processing board through a wire for circuit connection, and the power board 22 is used to convert voltage, transmit voltage to the central control board 21 and monitor voltage; and the interactive processing board is connected to the power board 22, and is used to receive the instruction of the switch key in the function key and transmit it to the power board 22 to shut down the circuit. The interactive processing board is used to receive instructions input by input components such as function keys and touch screens and transmit them to the central control board 21, and respond to the control of the central control board 21 to control display screens such as touch screens to perform corresponding displays.

[0043] The central control board 21 integrates at least a central processing module, a signal feedback module for receiving sensor signals, a driving module for controlling the operation of multiple booster pumps 61, and multiple groups of line interfaces for connecting wires. The signal feedback module and the driving module are both connected to the central processing module circuit; the central control board 21 is connected to the circuits of each sensor and the interactive processing board through wires, and is directly connected to the multiple booster pumps 61 through wires, and controls the operation of multiple booster pumps 61 through the central processing module and the driving module. In this way, all power parts or multiple power parts on the blood treatment device, such as multiple booster pumps 61, and sensors for monitoring and feedback, are uniformly controlled by the central control board 21, rather than setting up multiple control boards for separate control, which can not only simplify the circuit, reduce the cumbersome connection and conversion between circuit modules, but also improve the utilization of processors such as control chips, avoid resource waste, and help save hardware costs. At the same time, the number of circuit boards is small, the central control board 21 has a high degree of integration, the wires of each component are connected to the central control board 21, the internal wiring of the equipment is neat, the wire and line interfaces are concentrated, and the wiring of the lines is clear at a glance, which is convenient for quickly checking all the line connectors of the function keys, the line connectors of the indicator lights, etc., and convenient for observing the operating status of the equipment. At the same time, all lines can be maintained on one panel, which effectively improves the convenience of maintenance.

[0044] Specifically, the booster pump 61 is a peristaltic pump, which pressurizes the liquid by squeezing the liquid tube through the motor-driven extrusion mechanism. After the control module and the drive module for controlling the booster pump 61 are integrated on the central control board 21, they can be directly connected to the motor through a wire, and there is no need to set up circuit boards such as IC boards in the middle. The number of booster pumps 61 can be set according to the actual needs of the product, and is not limited here. For blood purification equipment, the pump group 60 can be provided with four or five booster pumps 61, and these four or five booster pumps 61 can be directly connected to the central control board 21. Of course, in special cases, an IC board can also be set next to a booster pump 61, and the remaining booster pumps 61 are all connected to the central control board 21.

[0045] The interactive processing board may include a substrate and a control main board plugged into the substrate, the substrate is used to connect with the function key board (referring to the circuit board on which the function keys are installed) and the touch screen board (referring to the touch screen circuit board) circuit, and the control main board is used for signal conversion. Alternatively, in the present application, the interactive processing board is an integrated single-board structure and integrates a processing module, a signal transmission module and a line interface, and is connected with the function key board and the touch screen board circuit; that is, it is equivalent to integrating the substrate and the control main board into a processing board, directly connecting the input circuit boards such as the function key board and the touch screen board, and the central control board 21, further improving the integrated setting of the circuit, improving the convenience of maintenance, and reducing the complexity of the circuit.
