Novel injector for cleaning metal tracheostomy cannula

Abstract

The invention relates to the technical field of injectors, and discloses a novel injector for cleaning a metal tracheostomy cannula. The novel injector comprises an injection cylinder, the bottom of the injection cylinder is communicated with a connector, the left side and the right side, close to the connector, of the bottom of the injection cylinder are fixedly connected with clamping blocks, and the upper portion of the injection cylinder is fixedly connected with a connecting piece; and the inner side wall of the injection cylinder is fixedly connected with a plastic film, and a containing cavity is formed between the lower portion of the plastic film and the injection cylinder. According to the designed injector, a user firstly connects the connector into a tracheostomy cannula opening to be fixed, holds the injection cylinder with one hand, holds a piston handle with the other hand to pierce the plastic film downwards and then lifts the the piston handle upwards, so that a plastic sheet is clamped in a rubber plug, and after the plastic film is broken, a hydrogen peroxide solution wets a compressed cotton sliver; when the worker pushes the piston handle downwards again, the rubber plug moves downwards to push the compressed cotton sliver to move downwards, the compressed cotton sliver can be pushed into the metal tracheostomy cannula, and cleaning of the inner wall of the metal tracheostomy cannula is facilitated.

Description

technical field [0001] The invention relates to the technical field of injectors, in particular to a novel injector for cleaning metal gas cutting sleeves. Background technique [0002] A syringe is a common medical device. As early as the 15th century, the Italian Catinelle proposed the principle of the syringe. The gas or liquid is withdrawn or injected mainly with a needle. [0003] Syringes are also used in medical equipment, containers, and scientific instruments such as some chromatography to inject through a rubber septum. According to medical history books, the initial form of the syringe was an enema. [0004] Generally, syringes are used as injection equipment in medical treatment, and metal gas cutting sleeves are sometimes used in medical treatment. Medical staff find it very inconvenient to clean the metal gas cutting sleeves, and the cleaning is not thorough enough. Through the improvement of traditional syringes, Design a new type of syringe for cleaning t...
