A balloon inflation pressure pump

Abstract

The invention discloses a balloon dilatation pressure pump comprises a handle, a piston seat and a pusher. The handle and the piston seat are in inverted connection, the piston seat extends into a sleeve, and a pressure gauge and a high-pressure extension tube are connected to the front end of the sleeve. The balloon dilatation pressure pump is characterized in that the middle of the handle is provided with a thread structure, middles of the upper and lower sliders are provided with semicircular threads, lead column holes and guide columns are arranged on two sides of the upper and lower sliders, and lead columns are arranged on upper and lower covers and penetrate through the lead column holes of the upper and lower sliders to fit the upper and lower sliders after the upper and lower covers are closed. The pusher is provided with guide grooves, and the guide columns on the upper and lower sliders can be movably embedded into the guide grooves to match with the semicircular threads of the upper and lower sliders through the thread structure of the handle, so that reliability in pressurizing is guaranteed. Further, stability in pressurizing is guaranteed by arranging the guide grooves on the pusher. The semicircular threads of the upper and lower sliders and the thread structure of the handle can be effectively separated during pressure removal by the aid of the guide grooves of an inclined section, and simplicity, rapidness and effectiveness in pressure removal are achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a balloon inflation pressure pump. Background technique [0002] At present, there are more and more clinical applications of balloon dilatation in the treatment of cardiovascular diseases. In the operation of cardiovascular stenosis and blockage, according to the need, the balloon is filled with liquid through the balloon expansion pressure pump, thereby changing the pressure and shape of the balloon. When in use, the balloon expansion pressure pump pressurizes the contrast agent or saline solution into the patient's cardiovascular disease, so that the CT equipment can clearly monitor the surgical treatment and determine the patient's disease; at the same time, it can also monitor the blood vessel disease. The balloon used in the expanded expandable stent is pressurized, decompressed, etc., so that the balloon expands and contracts to achieve the purpose of expanding blood vessel...
