Disposable medical high-pressure jet pump and its application method

Abstract

The invention discloses a disposable medical high-pressure jet pump and an application method thereof, comprising: a pump body, a through hole of a concentric and coaxial arrangement is arranged in the axial direction of the pump body, one end of which is matched with a water outlet mechanism, and the other end is matched with a piston to Provide a movement area for the reciprocating motion of the piston, and the through hole is also provided with a water inlet hole that is perpendicular to it and communicated with it; the main engine is provided with a push rod matched with the end of the piston; A blind hole is defined on the matching side of the rod; a plurality of positioning balls are arranged on the wall of the hole defining the blind hole, and arc grooves are arranged on the circumferential direction of the push rod to match the spatial layout of the positioning balls. The present invention provides a disposable medical high-pressure jet pump, which is a fast and reliable technical solution that enables quick installation, connection and disassembly of the pump body and the host.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable medical high-pressure jet pump used in wound debridement and an application method thereof. Background technique [0002] High-pressure jets have been used in clinical medical activities, mainly through pumps to pressurize sterile saline, and then form high-pressure jets through small nozzles on the pump body. Clean up. [0003] Through the existing technology and visible patents, high-pressure jet pumps are divided into two categories: one is a single-piston pump, and the other is a double-piston pump. The inhaled saline is pushed out of the outlet hole through the reciprocating movement of the piston to complete the debridement of the wound surface. However, in actual use, if the piston and the push rod are manually pushed, the flow rate and pressure stability of the outlet water will not be good. , and it is prone to cut-off, but if it is connected with other equipment to pro...

[0003] Through the existing technology and visible patents, high-pressure jet pumps are divided into two categories: one is a single-piston pump, and the other is a double-piston pump. The inhaled saline is pushed out of the outlet hole through the reciprocating movement of the piston to complete the debridement of the wound surface. However, in actual use, if the piston and the push rod are manually pushed, the flow rate and pressure stability of the outlet water will not be good. , and it is prone to cut-off, but if it is connected with other equipment to provide reciprocating power through other equipment, it is necessary to connect the push rod to other equipment so that the power output after connection is stable, but the two The stability and speed of the connection cannot be guaranteed, which will affect the actual operation
