The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] A medical pressure pump that is easy to plug and unplug, such as Figures 1-13 As shown, it comprises a pump body 1, the bottom end of the pump body 1 is threadedly connected to a handle 2, and the pump body 1 can be operated by rotating the handle 2;

The other end of the fixed tube 5 is movably connected to a connecting tube 6. After the fixed tube 5 is connected to the connecting tube 6, the pressure inside the pump body 1 can be transmitted through the hose 4 to facilitate subsequent treatment needs.
