Balloon dilation pressure pump

Abstract

The invention discloses medical equipment and particularly relates to a balloon dilation pressure pump. The balloon dilation pressure pump comprises a tube, a handle, a piston, an adjusting rod, an adjusting switch, a connecting block and an adjusting shaft and is characterized in that the tube is fixedly connected with the handle, the piston is located in the tube, the piston is in close contact with the inner wall of the tube and can move along the inner wall of the tube, the adjusting rod is provided with an outer thread, the adjusting switch is provided with a concave cavity, the bottom of the cavity is provided with an inner thread, the adjusting switch is located in the handle, one end of the adjusting rod penetrates the adjusting switch, extends into the tube and is fixedly connected with the piston, and the outer thread on the adjusting rod is matched with the inner thread; the connecting block is located in the cavity and rotatably connected with the adjusting switch; the adjusting rod is located in the connecting block, the connecting rod can rotate around the adjusting rod, and two ends of the adjusting rod are fixed to the handle. The balloon dilation pressure pump is simple in structure, capable of lowering medical treatment cost, capable of avoiding thread wear and accurate and labor-saving in pressurizing operation.

Description

technical field [0001] The invention relates to a medical device, in particular to a balloon inflation pressure pump. Background technique [0002] Interventional surgery is a minimally invasive treatment method of percutaneous puncture. This surgery does not require surgery, has minimal trauma, quick recovery, and good results. It is currently a relatively advanced and effective treatment method for cardiovascular diseases. [0003] The balloon inflation pressure pump is a medical device used to pressurize the balloon dilation catheter and expand the balloon to achieve the purpose of dilating blood vessels or indwelling stents in blood vessels during interventional therapy. The balloon inflation pressure pump expands or contracts the balloon dilation catheter. It can fill the balloon with fluid as needed to change the pressure and shape of the balloon, expand the balloon, detect the pressure inside the balloon and deflate the balloon during the balloon inflation process.

Problems solved by technology

[0004] At present, a large number of imported products are used clinically. Their structures are complex and expensive, which brings heavy economic pressure to patients.

In addition, the existing products realize pressurization and decompression through screw transmission. The process of rotating pressurization requires two-handed operation. During use, it is easy to cause pressurization deviation due to the phenomenon of slipping wires, which is not conducive to the smooth progress of interventional therapy.
