Abstract

The invention discloses a balloon expansion pressure pump which comprises a pump shell and a hand lever, a pump bottle is arranged in the pump shell, a piston head is arranged at one end of the hand lever, a piston cavity is formed in the pump bottle, the piston head is matched with the piston cavity, the hand lever is hollow, a pressure relief cavity is formed in the middle of the hand lever, and a pressure relief valve is arranged in the pressure relief cavity. A pressure relief cavity is formed in the piston head, a pressure relief rod is arranged in the pressure relief cavity in a sliding mode, a pressure relief groove is further formed in the end of the piston head, a pressure relief block is arranged in the pressure relief groove in a sliding mode, the pressure relief block is fixedly connected with the pressure relief rod, and a pressure relief channel is formed in the pressure relief block. The pressure relief channel is suitable for being communicated with the piston cavity and the pressure relief cavity when the pressure relief rod is pushed. According to the scheme, through the arrangement of the hollow hand rod and the pressure relief rod in the hand rod, in the actual use process, the pressure relief rod can be pushed to communicate with the piston cavity and the pressure relief cavity except the hand rod, the selectable pressure relief mode is improved, targeted use is facilitated, and the safety performance is improved.

Description

technical field [0001] The present invention belongs to, in particular, to a balloon inflation pressure pump. Background technique [0002] The balloon expansion pressure pump is used in PTCA and surgery to pressurize the balloon expansion catheter, so as to expand the balloon to achieve the purpose of dilating blood vessels or placing stents in blood vessels. [0003] Most of the existing pressure pumps are screw-propelled pressure pumps, and they are usually equipped with a thread pop-up structure to ensure the expansion effect of the balloon and the pressure relief after use. There are two pressure relief methods. , by reversing the hand lever to relieve pressure, and secondly, by pressing the button and pulling out the hand lever to relieve pressure. The pressure relief speed of the former is slow, and the pressure relief process of the latter is difficult to control the pressure, which reduces the safety performance. Contents of the invention [0004] The object of ...
