CN2460109Y - Filtering-type injector - Google Patents

Abstract

The utility model relates to a filtering-type injector belonging to medical articles, which is formed by assembling an injector, a medicine liquid filtering assembly, and an injecting needle head. The utility model is mainly suitable for the application in the process of preparing medicine liquids before intravenous drips or injections in hospitals, and can be directly used for injections. The utility model has the characteristics of simple structure, convenient operation, good filtering effect, medical safety assurance, and low cost.

Description

The filtering type syringe

This utility model belongs to medical medical supplies, is mainly used in drop, the preceding preparating liquid use of injection, also can be directly used in injection and use.

Medical supplies such as product structure design such as syringe whether rationally, the fine or not medical effect that directly affects of product quality.At present, the various syringes that use in medical treatment comprise the syringe and the disposable syringe of glass material, all are directly to be linked and packed by syringe and injection needle to constitute, and do not have the defecator of medicinal liquid.In actual medical, because drug quality, perhaps the multiple reasons such as repeated multiple times operation in the medicinal liquid process for preparation are easy to bring into or take place suspended impurity in medicinal liquid, and the syringe of the no defecator that uses is at present given patient's drop or very easily the impurity in the above-mentioned medicinal liquid is injected in patient's body when injecting this type of medicinal liquid, reduce therapeutic quality, even produce malpractice.

The purpose of this utility model is exactly at deficiency that exists in the prior art and problem, design provides a kind of filtering type syringe, by the structure of medical filtration assembly is installed between syringe and injection needle, reach and solve and avoid because drug quality, perhaps all kinds of minute impurities of bringing in the medicinal liquid preparation in the medicinal liquid are injected in the patient body, improve medical effect, alleviate patient's misery, guarantee the purpose of medical safety.

Basic design of the present utility model is, the medical filtration assembly is installed between syringe and injection needle, its syringe lower end closely is inserted in the bellmouth seat of medical filtration assembly one end, the other end of medical filtration assembly closely is inserted in the bellmouth seat of injection needle, constitutes the filtering type syringe.

This utility model is particularly useful for using in the medicinal liquid process for preparation before patient's drop or the injection, also can be directly used in injection and use, and has simple in structure, easy to use, good filtration effect, characteristics with low cost.

Accompanying drawing is a filtering type syringe overall structure sketch map.

Piece number explanation among the figure:

1. syringe 2. medical filtration assemblies 3. injection needles

Below in conjunction with accompanying drawing this utility model optimum implementation is described in detail.Between syringe 1 and injection needle 3, medical filtration assembly 2 is installed, its syringe 1 lower end closely is inserted in the bellmouth seat of medical filtration assembly 2 one ends, the other end of medical filtration assembly 2 closely is inserted in the bellmouth seat of injection needle 3, and syringe 1, medical filtration assembly 2 and injection needle 3 intracavity inter-connections so far constitute the filtering type syringe.

When using this device to carry out the medicinal liquid preparation, earlier the filtering type syringe is utilized injection needle 3 to be inserted in medical use liquid (sodium chloride injection for example, glucose solution etc.) on the bottleneck, medical use liquid is via injection needle 3 in the bottle, medical filtration assembly 2 is sucked in the syringe 1, there is suction the syringe 1 of liquid in the bellmouth seat of medical filtration assembly 2, to pull up (this moment, medical filtration assembly 2 and injection needle 3 still were retained on the medical use liquid bottleneck) then, with injection needle 3 close fit that are inserted in earlier on the dissolved powder medicine bottleneck of need, quantitative liquid is injected the dissolving of liquefying in the powder bottle again.After all powder becomes medicinal fluid, opposite with aforesaid operations, the medicinal liquid that liquefies is sucked in powder bottle with syringe 1, insert again on the medical filtration assembly 2 on the medical use liquid bottleneck, medicinal liquid is injected the medical use liquid bottle, can use by drop.This device also can be directly used in application such as intramuscular injection.
