AI Technical Summary

Technical Problem

In the prior art, when a doctor cleans local wounds for trauma patients, the needle hole of the syringe is small, the flushing efficiency is low, and it is easy to injure the patient, and continuous flushing cannot be achieved, and the operation convenience and safety are insufficient.

Method used

A wound rinser is designed, including an injection container, piston, infusion tube and driving mechanism. Through the axial movement of the piston, combined with the one-way valve structure, the liquid chamber volume is compressed and expanded, the extraction and discharge of normal saline is realized, and continuous flushing is realized.

Benefits of technology

Continuous rinsing of wounds is achieved, no need to replace the irrigator, avoid the use of needles, improve the safety and convenience of operation, and flexibly select the capacity of the normal saline bottle according to the wound area.

Abstract

The utility model relates to the technical field of medical supplies, and particularly discloses a wound irrigator which comprises an injection container, a piston, an infusion tube and a driving mechanism. The injection container is provided with a flushing pipe; the piston is arranged in the injection container, and a liquid cavity is formed between the piston and the injection container; one end of the infusion tube is connected with a normal saline bottle; the driving mechanism is used for driving the piston to axially move so as to compress or enlarge the volume of the liquid cavity; a first one-way valve is arranged on the flushing pipe, and a second one-way valve is arranged on the infusion pipe; the first one-way valve and the second one-way valve are matched with each other, so that when the driving mechanism drives the piston to enlarge the volume of the liquid cavity, the liquid cavity can only suck a medium from the liquid conveying pipe; the first one-way valve and the second one-way valve are matched with each other, so that when the driving mechanism drives the piston to compress the volume of the liquid cavity, a medium in the liquid cavity can only be discharged from the flushing pipe; the wound flusher is good in convenience, high in safety and capable of achieving continuous flushing.
