Quick air inflation, discharge and control device for expanding balloon

Abstract

The invention discloses a quick air inflation, discharge and control device for expanding a balloon. The quick air inflation, discharge and control device for expanding the balloon comprises a handle body, a push handle, a pump body and a connecting piece, the pump body is provided with a pressure releasing component capable of realizing self-locking, the pressure releasing component comprises a grip, a cover body arranged in the grip, a releasing mechanism arranged on the cover body, and a self-locking mechanism capable of locking the releasing mechanism, a shaft hole is formed in the cover body, and a push rod is arranged in the shaft hole and capable of reciprocating along the axial line thereof. The quick air inflation, discharge and control device for expanding the balloon is novel in structure, and the grip is provided with the pressure releasing component capable of realizing self-locking; the quick air inflation, discharge and control device for expanding the balloon conforms to the human engineering, the operation is facilitated, the safety performance is high, and misoperation is avoided; a pressure display component is arranged at one side of the pump body, and the pressure display component is convenient for examining the numbers on the pump body and placing.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an inflation and inflation control device for an inflatable balloon. Background technique [0002] Clinically, the surgical dilator is a surgical instrument used for patients with cardiovascular stenosis and blockage. It is used to expand the balloon during balloon expansion, monitor the pressure inside the balloon and deflate the balloon. When in use, the pressure pump pressurizes the contrast medium and saline solution into the patient's diseased area. This process gives CT equipment a clear monitoring of the surgical treatment and confirmation of the patient's affected area. During the treatment of the patient, the affected area must be expanded. The metal stent is placed. During the surgical treatment, the pressure pump pressurizes the balloon used for placing the stent and expanding the stent. When the expected purpose and requirements are achieved, the pressure pump...

AI Technical Summary

Problems solved by technology

[0003] At present, the pressure pumps used in clinical practice are complex in structure and require high manufacturing precision. They basically rely on imports. It is installed on the front of the pump body, blocking part of the scale parameters on the pump body, making it difficult to observe the data, which is not conducive to the normal operation of the operation; at the same time, the structure of the pressure relief device is complicated, which cannot achieve the purpose of rapid pressure release, and the key position The design is not ergonomic, easy to misuse, inconvenient to operate, and poor in reliability; in addition, the pressure cannot be well controlled when the pressure is released
