Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology for hemodialysis machines, specifically to a novel peristaltic pump with a small volume. Background Technology

[0002] In a hemodialysis machine, the peristaltic pump is one of the core components, mainly used to propel blood or dialysate through the extracorporeal circulation system to ensure the continuity and safety of the dialysis process.

[0003] The pump head of the existing peristaltic pump is driven by a drive motor, which is controlled by a control module. The control module and the peristaltic pump are installed independently and connected by a connecting cable. The control module regulates the speed of the drive motor to meet the operating requirements of the peristaltic pump.

[0004] In existing technologies, the control module is usually installed separately from the peristaltic pump in the hemodialysis machine and connected to the drive motor of the peristaltic pump via an external connecting cable. This connection method increases the complexity of the structure and results in a larger overall size of the peristaltic pump, which occupies more installation space and makes the peristaltic pump unsuitable for compact equipment.

[0005] Therefore, it is necessary to design a small-sized peristaltic pump. Utility Model Content

[0006] This application provides a novel peristaltic pump with a small volume, which solves the technical problems of peristaltic pumps having a lot of external wiring and occupying a lot of space.

[0007] This application provides a novel peristaltic pump with a small volume, comprising: a motor for driving the pump head and a control component disposed at one end of the motor; the control component is detachably electrically connected to the motor; a socket assembly is embedded in the housing at one end of the motor, and a plug assembly is fixedly disposed on the side of the control component near the motor; the socket assembly and the plug assembly are plugged into and electrically connected.

[0008] By adopting the above technical solution, the control component is detachably fixed to the motor housing through the connection and cooperation of the socket assembly and plug assembly. This optimizes the external connection line between the control component and the motor, avoids excessive space occupation caused by the separate setting of the control component and the peristaltic pump motor, and realizes the overall compact structure of the peristaltic pump.

[0009] Preferably, the control component includes a flat control module integration board, and the plug assembly is located on the side of the control module integration board facing the motor.

[0010] By adopting the above technical solution, the control module is integrated on a flat control module integration board, which further reduces the size of the peristaltic pump and reduces the space occupied by the peristaltic pump.

[0011] Preferably, the control component also includes a flat protective shell, which covers the outside of the control module integrated board, and the protective shell is detachably connected to the motor.

[0012] By adopting the above technical solution, a removable protective shell is installed on the control module integration board to prevent the control module integration board from being interfered with by the external environment and to improve the stability of the peristaltic pump operation.

[0013] Preferably, one end of the motor is provided with a plurality of first connecting holes circumferentially spaced around the axis, the plurality of first connecting holes being circumferentially located outside the socket assembly, and a plurality of first bolts are provided at intervals on the outer periphery of the protective shell, the plurality of first bolts extending along the motor axis, and each first bolt being threadedly connected to the corresponding first connecting hole.

[0014] By adopting the above technical solution, multiple first bolts are used to connect the protective shell and the motor, achieving a detachable function, and the simple structure is easy to manufacture.

[0015] Preferably, the control module integration board and the top plate of the protective shell are stacked, and the control module integration board is fixed to the top plate of the protective shell in a detachable manner.

[0016] By adopting the above technical solution, the control module integrated board can be detachably fixed to the protective shell. The control module integrated board can be separated from the motor synchronously by separating the protective shell from the motor, thus avoiding human impact on the control module integrated board.

[0017] Preferably, the top plate of the protective shell is provided with four second connecting posts spaced circumferentially, and the control module integration plate is provided with four second bolts. All four second bolts penetrate the control module integration plate, the head of each second bolt is located on one side of the plug assembly, and each second bolt is threadedly connected to the corresponding second connecting post.

[0018] By adopting the above technical solution, the control module integrated board is fixed to the protective shell by the second bolt, realizing the detachable function, and the simple structure is easy to manufacture.

[0019] Preferably, the socket assembly includes three socket pieces, and the plug assembly includes three plug pieces. The three socket pieces are circumferentially spaced around the axis of the motor at one end of the motor, and the three plug pieces are correspondingly spaced on the control assembly. Each plug piece is plugged into and electrically connected to the corresponding socket piece.

[0020] By adopting the above technical solution, the three spaced sockets and plugs are connected to limit the movement of the control components, thereby improving the connection stability of the control components.

[0021] Preferably, each socket component is detachably mounted on the motor housing by plugging in, and each socket component has a limiting plate at one end that fits into the motor housing.

[0022] By adopting the above technical solution, the socket component is fixed to the motor housing by plugging it in, which facilitates the disassembly of the socket component and sets a limiting plate to prevent the socket component from sliding into the motor.

[0023] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0024] 1. By using plug and socket components, the control components are plugged into the motor, optimizing the external connection between the control components and the motor and reducing the space occupied by the peristaltic pump;
