[0020] like Figures 1 to 3 As shown, the present embodiment is an infusion pump head cleaning device, comprising a body 1, a heating plate 101 is installed at the bottom end of the inner cavity of the body 1, by setting the heating plate 101, the heating plate 101 is mainly used to heat the liquid in the inner cavity of the body 1, a plurality of mounting grooves 102 are opened on the surface of the inner cavity of the body 1, the inner cavity of the mounting groove 102 is respectively installed with a threaded rod 2 and a guide column 201, a motor 202 is installed at one end of the threaded rod 2, by setting the motor 202, the motor 202 is mainly used to drive the threaded rod 2 to rotate, the rotation of the threaded rod 2 can drive the mounting ring 203 to move up and down, the up and down movement of the mounting ring 203 can drive the barrel 3 to move up and down, the threaded rod 2 can rotate, and the mounting ring 203 can rotate. A mounting ring 203 is commonly installed on the surface of the rod 2 and the guide column 201. By setting the mounting ring 203, the mounting ring 203 is mainly used to install the barrel 3. The inner cavity of the mounting ring 203 is installed with the barrel 3. The bottom end of the inner cavity of the barrel 3 is provided with a plurality of limiting holes 301. By setting the limiting holes 301, the inner cavity of the limiting holes 301 is mainly used to place the piston rod of the pump head. A limiting mechanism is installed on the bottom end of the inner cavity of the barrel 3 outside the limiting holes 301. By setting the limiting mechanism, the limiting mechanism is mainly used to limit the piston rod of the pump head to avoid shaking when cleaning the piston rod of the pump head, which causes wear or scratches on the surface of the piston rod of the pump head and affects the use.

[0021] Specifically, the limiting mechanism includes a screw 4, a limiting plate 401 and a knob 402. The screw 4 is installed at the bottom end of the inner cavity of the barrel 3 outside the limiting hole 301, and the limiting plate 401 is installed on the surface of the screw 4. The knob 402 is installed on the surface of the screw 4 at one end of the limiting plate 401. By setting the limiting plate 401, when the piston rod of the pump head is placed into the inner cavity of the limiting hole 301, the knob 402 is rotated to move the limiting plate 401 downward, and one end of the limiting plate 401 presses one end of the piston rod of the pump head to prevent the barrel 3 from moving up and down when cleaning the piston rod of the pump head, causing the piston rod of the pump head to shake or detach from the inner cavity of the limiting hole 301, thereby causing the surface of the piston rod of the pump head to be worn or scratched, affecting use.

[0022] Furthermore, a plurality of limit grooves 5 are provided at one end of the mounting ring 203, and a limit block 501 is installed in the inner cavity of the limit groove 5. One end of the limit block 501 is connected to the other end of the barrel 3. By holding the handle 7 and rotating the barrel 3 counterclockwise by ninety degrees through the limit groove 5, the barrel 3 can be screwed out from the inner cavity of the mounting ring 203. When installing the barrel 3, the barrel 3 is installed back into the inner cavity of the mounting ring 203 and rotated clockwise by ninety degrees to fix the barrel 3, thereby making it convenient for the staff to place the piston rod of the pump head into the inner cavity of the limit hole 301.

[0023] Furthermore, a plurality of circular holes 6 are provided on the surface of the barrel 3. By providing the circular holes 6, the liquid in the inner cavity of the body 1 will enter the inner cavity of the barrel 3 through the circular holes 6 to clean the piston rod of the pump head.

By setting the water inlet pipe 701 and the water outlet pipe 702, it is mainly used for the water inlet and water outlet of the main body 1. At the same time, the valve 703 can control the opening and closing of the water outlet pipe 702.

[0025] Furthermore, a plurality of gaskets 8 are installed at one end of the main body 1. The gaskets 8 are made of rubber material and mainly play an anti-slip role.

[0026] The method of using this embodiment is as follows: use a pipeline to connect with the water inlet pipe 701, and inject cleaning liquid into the inner cavity of the main body 1, then start the heating plate 101, and the heating plate 101 heats the liquid in the inner cavity of the main body 1. At this time, hold the handle 7 and rotate the barrel 3 counterclockwise for 90 degrees, so that the barrel 3 can be screwed out of the inner cavity of the mounting ring 203, and the limit plate 401 can be removed, and then the piston rod of the pump head is prevented from being in the inner cavity of the limit hole 301, and installed back to the limit plate 401, and the knob 402 is rotated to move the limit plate 401 downward, and one end of the limit plate 401 presses one end of the piston rod of the pump head, and then the barrel 3 is installed on the mounting ring The inner cavity of body 1 is fixed by rotating it ninety degrees clockwise. At this time, start motor 202 and drive threaded rod 2 to rotate. The rotation of threaded rod 2 can drive mounting ring 203 to move up and down. The up and down movement of mounting ring 203 can drive barrel 3 to move up and down. The cleaning liquid in the inner cavity of body 1 will enter the inner cavity of barrel 3 through circular hole 6 to clean the piston rod of pump head. When cleaning is completed, threaded rod 2 drives barrel 3 to move upward and rotates barrel 3 ninety degrees counterclockwise again. Barrel 3 can be screwed out from the inner cavity of mounting ring 203, and the limiting plate 401 can be removed to remove the piston rod of the pump head in the inner cavity of limiting hole 301.
