Description

≪ RTI ID = 0.0 > Cartridges-Mounted Syringe &

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a syringe for mounting a cartridge containing an injection, and more particularly to a syringe capable of mounting a plurality of cartridges.

Conventional syringes require special production of disposable plastic syringes and new syringes every time the injections are changed.

In addition, when a solid is dissolved by injection, it is more likely that solid powder (in particular, biological extract, etc.) is adsorbed on the plastic surface inside the syringe. In order to prevent this, the syringe itself is made of glass with low durability (possibility of breakage), and when the inside of the syringe is coated with glass, its production cost is high and it is very disadvantageous to use in general purpose.

In addition, the conventional syringe receives and injects a single injection into the barrel main body of the syringe. When a plurality of injections are mixed and accommodated, the injection failure due to coagulation or precipitation due to physical and chemical reactions, Or injections may be denatured or discolored, and there are components which are separated and accommodated in separate containers and which must be mixed and used in use.

In this case, the injected injected medicines need to be injected directly by the user before injecting them, and mixed with the injected injections, which inconveniences the user.

In the case where it is necessary to inject the plurality of injection agents at the same time, or when it is necessary to dissolve the solid preparation as a dissolving liquid with an injecting solution, it is not necessary to mix different injection agents in advance, Korean Patent Registration No. 0171682 discloses that each injecting agent can be housed in a separate and formed room in a syringe and can be mixed when injected.

However, in the syringe disclosed in Korean Patent No. 0171682, various injections for solid preparations are contained in a syringe, and when various injections are mixed, various operations such as rotation of the cylinder and passage are required. There is a possibility of being exposed to the pollution without being prepared for the case where it is difficult to operate so that the openings coincide with each other and must be promptly treated. Further, since the syringe is of a buried type, there is a problem that it is difficult to seal and store for a long period of time.

Numerous papers and patent documents are referenced and cited throughout this specification. The disclosures of the cited papers and patent documents are incorporated herein by reference in their entirety to better understand the state of the art to which the present invention pertains and the content of the present invention.

The present inventors have made efforts to develop a syringe capable of simultaneously injecting a plurality of injection agents while minimizing contamination by solving the problems of the conventional syringe described above. As a result, the ampoule containing the injection agent is manufactured in the form of a cartridge including a thin cap, and an opening portion capable of breaking the cap is installed in the cartridge portion accommodating the syringe body barrel or other injection agent into which the cartridge is inserted The present inventors have completed the present invention by confirming the fact that a plurality of injection agents can be mixed while the stopper is broken by pressing and pressing without complicated operation.
