Novel balloon dilatation pressure device capable of being operated by one hand

Abstract

The invention discloses a novel balloon dilatation pressure device capable of being operated by one hand. The device comprises a pushrod, a handheld control assembly, a drum, a pressure gauge, a high pressure extension tube and a rotary joint, wherein the pressure gauge is arranged at the outlet of the drum, one end of the high pressure extension tube is fixedly connected with the drum, and the other end of the high pressure extension tube is fixedly connected with the rotary joint; and the pushrod penetrates through the handheld control assembly and stretches into the drum, the inside of the drum is closely matched with the front end of the pushrod, and the drum is fixedly connected with the handheld control assembly. Through the mode, one-handed operation can be achieved, and rapid pressurization, precise pressurization and rapid pressure release can be achieved respectively through control of positions of a control module.

Description

technical field [0001] The invention relates to the field of disposable medical devices, in particular to a balloon pressure pump used for coronary heart intervention therapy and peripheral intervention therapy and operation. Background technique [0002] The balloon inflation pressure pump is mainly used to expand medical balloons, pressurize and monitor the pressure during balloon inflation. In coronary interventional surgery and peripheral interventional surgery, balloon dilation pressure pump is a commonly used and necessary medical device, and precise pressure control is very important. Invention patent (CN 101559253A) discloses a balloon expansion pressure pump, the main structure of which uses the rack on the push rod to engage in threaded engagement with the inner wall of the screw cap on the sleeve, and realizes pressurization and unloading through thread transmission. There is a phenomenon that the rotation and pressure of the two-handed operation are slow and pro...

Invention patent (CN 101559253A) discloses a balloon expansion pressure pump, the main structure of which uses the rack on the push rod to engage in threaded engagement with the inner wall of the screw cap on the sleeve, and realizes pressurization and unloading through thread transmission. There is a phenomenon that the two-handed operation rotates and presses slowly and is prone to slipping

Existing balloon dilation pressure pump products usually require both hands to operate during operation and pressure to pressurize and release the balloon. The operation is complicated, so there may be problems caused by the doctor's personal operating habits. The problem of inconvenient operation, and the slow rotation and pressurization is difficult to operate, which is not conducive to the operation of the operation
