A pressure pump and balloon dilation device

Abstract

The application discloses a pressure pump and balloon dilatation device, and relates to the technical field of medical devices. The pressure pump is used for balloon dilatation and comprises a pump body and a handle. The pump body comprises a barrel and a push rod. The handle comprises a handle shell, a movable locking mechanism, a pulley transmission mechanism and a control knob. The handle shell is arranged on the outer periphery of the connection between the push rod and the barrel. The movable locking mechanism has a locking position and an unlocking position. One end of the pulley transmission mechanism is connected with the movable locking mechanism. The control knob is arranged on the handle shell and connected with the other end of the pulley transmission mechanism. The control knob is used for driving the pulley transmission mechanism to move under the action of external force, so as to drive the movable locking mechanism to move, so that the movable locking mechanism is switched from the locking position to the unlocking position. The application improves the structure of the balloon dilatation pressure pump. The pressure pump can be quickly switched between pressure maintaining and pressure releasing. The pressure pump is simple and convenient to operate, saves labor and improves the efficiency of operation and ensures the safety of operation.
