Description

Syringe with double chamber

The present invention relates to a syringe having a double chamber, and more particularly to a syringe having a double chamber is a plurality of chemical liquids or powders are stored separately inside the syringe and conveniently mixed and used in the actual procedure.

In general, injections are contained in ampoules or vials, and when injected, the ampoules are first cut, or the injections stored therein are penetrated through the rubber caps of the vials and then injected into the patient.

As described above, injection may be carried out by injecting a single injection as well as by mixing more than one medicine as described above.

For example, it is the case of the injection used as a therapeutic agent, such as deformable knee joint disease and periarthritis of a shoulder.

For example, since only the hyaluronic acid sodium drug as a therapeutic agent has an excessive pain when injected, a lidocaine hydrochloride or the like is injected together as a local anesthetic.

In this case, the ampoule was cut and the sodium hyaluronate preparation contained in the syringe was inhaled into the syringe, and then the needle was penetrated through the rubber stopper of the vial. Inject.

On the other hand, as another example of mixing two or more drugs, powdered drugs such as antibiotics, steroids, vaccines, etc. in vials may be enclosed, and the solution or dilution solution may be put in an ampoule.

In this case, the ampoule is cut to suck the solution in the ampoule into the syringe, and then the needle is continuously penetrated through the rubber stopper of the vial to inject the solution in the syringe into the vial.

After the needle is removed, the vial is shaken to dissolve the powdered drug, and once again, the rubber stopper is penetrated by the needle to suck the dissolved injection into the syringe, and then the injection mixed with the syringe is injected into the patient.

In the conventional injection method, not only is it inconvenient to use the syringe because it has to be operated in several steps, but also the user may be injured by the glass piece of the ampoule when cutting the ampoule, There is a risk of causing infections such as AIDS.

In addition, in the process of cutting the ampoule, the ampoule fragment is mixed into the injection agent contained in the ampoule, or the rubber fragment of the vial is penetrated by the injection needle, a problem that the rubber fine particles are incorporated into the injection in the vial.

The incorporation of these foreign substances is confirmed by a microscope, and when injected into the body along with the injection solution will adversely affect the human body.

The present invention has been devised to solve the above-described problems, and its object is to provide a syringe which can be mixed and injected with a medicament in a simple and simple operation.

On the other hand, the objects of the present invention are not limited to the above-mentioned objects, and other objects that are not mentioned will be clearly understood by those skilled in the art from the following description.
