Medical saccule pressure pump with combination of straight push and rotary tuning

Abstract

The invention discloses a medical saccule pressure pump with combination of straight push and rotary tuning, which comprises a handle, a screw rod, a piston, a pump body and output equipment, and is characterized by further comprising a push rod, a crank, a fine tuning box and a pressure meter, wherein the top surface of the push rod is connected with the handle, and the bottom surface of the push rod is connected with the piston; the screw rod is inserted into the pump body and is hollow; the push rod is movably inserted into the screw rod for using; the bottom of the pump body is provided with a one-way valve and a pressure relief button; the fine tuning box is arranged above the pump body; the crank is used for driving the screw rod to move up and down through the fine tuning box after being rotated, so that the screw rod can be used for driving the piston to move downwardly in a fine tuning way. By adopting the medical saccule pressure pump, the defects of the conventional medical pressure pump are overcome; the pressure is measurable, pressurization is accurate, and the liquid injection amount or the aeration quantity is controlled accurately; and the medical saccule pressure pump has the characteristics of convenience for using, reliability, difficulty in sliding, and the like.

Description

1. Technical field [0001] The invention relates to a medical pressure pump, in particular to a medical balloon pressure pump used for filling and shrinking a medical balloon. 2. Background technology [0002] The medical balloon pressure pump is mainly used to expand the medical balloon, pressurize and measure and monitor the pressure. Medical balloons are mainly used in the interventional department, cardiology department, gastroenterology department, urology department, etc. to expand the narrow part of the human cavity, such as dilating blood vessels, dilating the biliary tract, etc. During the operation, pressure control is very important. At present, the pressure pumps used clinically have complex structures and require high manufacturing precision. Because the existing domestic technology is not yet mature enough, they basically rely on imports. Moreover, the existing pressure pump is not convenient to use. On the one hand, the rotation and pressurization is slow, and...

Problems solved by technology

At present, the pressure pumps used clinically have complex structures and require high manufacturing precision. Because the existing domestic technology is not mature enough, they basically rely on imports.

Moreover, the existing pressure pump is not convenient to use. On the one hand, the rotation and pressurization is slow, and the operation is difficult and requires more effort; The pressure is not easy to accurately control, the reliability is low, it is not conducive to surgical operation, and there is a hidden danger of accidents
