Description

Technical Field The present invention relates to a filter cap for a syringe,

The present invention relates to a filter cap for a syringe, and more particularly to a filter cap for a syringe and a method of manufacturing the same. More particularly, the present invention relates to a filter cap for a syringe, So that the metal tip can be easily inserted into the rubber stopper of the vial with a small force, and a method for manufacturing the same.

In general, a syringe is a device for injecting an injection liquid into the body. The injection liquid injected into a container such as an ampule or a vial is sucked into the cylinder and injected into the body. Such a syringe is composed of a cylinder in which a needle is coupled and in which a chemical solution is received, and a plunger provided in the cylinder so as to be able to advance and retract along the axial direction.

When injecting a human body with a syringe, the injection needle of the cylinder is inserted into the rubber lid of the vial or inserted into the broken mouth of the vial, the injection liquid is filled into the cylinder, and injected into the body of the human body Respectively.

However, when injecting the injection needle of the syringe through the rubber stopper of the syringe in the process of filling the syringe filled with the injector filled with the syringe using the syringe, part of the rubber syringe falls off at the moment of injection needle penetration, And the foreign substances are introduced into the cylinder of the syringe, thereby causing a fatal side effect to the human body.

In order to solve the above-mentioned problems, various types of syringe filter caps have been known so as to prevent foreign substances from flowing into the cylinder of the syringe. For example, Korean Patent Registration No. 1243396 Quot; used filter cap "(hereinafter, referred to as" filter cap for a syringe of a conventional example ") will be described below.

As shown in Fig. 8, the filter cap for a syringe of the related art has a structure in which an injection liquid inflow path 704 penetrates therein, and a needle needle insertion portion 704 connected to the injection liquid inflow path 704 so that the injection needle can be inserted. A housing through which a needle insertion path 706 is inserted and connected to the injection needle insertion path 705 in such a manner that a needle can be closely adhered and negative pressure is formed, And a filter 701 to be attached by fusion bonding to the communicating portion of the injection liquid inlet path 704 and the needle insertion path 705 so as to filter the injected injection liquid. The injection fluid inlet path 704 and the injection needle insertion path 705 are formed inside an ampoule insertion tube 702 (hereinafter referred to as "insertion tube").

The filter 701 is fixed to the communicating portion of the injection liquid inflow path 704 and the needle insertion path 705 by fusion bonding. A filter having a permeability of 5 탆 or less was used as the filter. In addition, the filter 701 may be provided through various materials that are chemically stable and can be melt-adhered without reacting with an injection solution. Particularly, the inner diameter of the injection liquid inflow path is larger than the inner diameter of the injection needle insertion path 705 so as to fix the filter through fusion.

However, the filter cap for a syringe of the above-described conventional example has the following problems.

First, in the filter cap for a syringe of the related art, the injection liquid inflow path is formed in the inner side of the insertion tube so as to enlarge the diameter for mounting the filter.

Therefore, the filter cap for a syringe of the related art has to expand the suction diameter of the filter so that the suction of the injection liquid can be performed well, so that the inside diameter of the injection liquid inlet path to which the filter is mounted must be expanded. Therefore, as described above, the outer diameter of the insertion tube must be necessarily expanded due to the expansion of the injection liquid inflow path. Therefore, when the insertion tube of the filter cap for a syringe of the prior art example is passed through the rubber stopper of the vial, the insertion tube does not penetrate well There was a problem that there were many inconveniences in use.

8, the filter cap for a syringe of the related art is provided with a resistance step 800 that causes resistance of fluid at the time of suction of the injection liquid at the front end of the injection needle insertion, There is a problem that the suction performance of the injection solution is deteriorated due to the resistance step (800).

On the other hand, a "syringe filter cap for a vial having a metal tip" (hereinafter, referred to as "a syringe filter cap of another conventional example") of Korean Patent Registration No. 1460465 as a filter cap for a syringe of another conventional example Respectively.

The metal tip 200 has a tubular shape and is inserted and fixed to the outer circumferential surface of a tubular injection port 106 protruding from the tip of the injection needle insertion path 104. Therefore, the filter 105 is attached and fixed to the tip of the needle insertion path 104, which is the inner rear of the injection liquid inlet 106.

In addition, the inner circumferential surface of the metal tip 200 and the outer circumferential surface of the injection liquid inlet 106 are attached with an adhesive (B).

In the syringe filter cap of the above-described conventional example, the diameter of the injection inlet is enlarged so as to mount the filter behind the injection inlet, which is the tip of the housing, like the filter cap for the syringe of the above- There is a problem that the metal tip does not penetrate the rubber stopper of the vial as the outer diameter of the injection inlet becomes larger and the outer diameter of the metal tip inserted into the injection inlet is expanded.

9, when the metal tip is fixed, an adhesive B is first applied to the outer peripheral surface of the injection liquid inlet 106, and then a metal The metal tip 200 is fixed through the process of inserting the tip 200. In the process of fixing the metal tip 200 as described above, the adhesive B is leaked to the outside between the rear end of the metal tip 200 and the front end of the needle insertion path 104, so that the leakage protrusion 300 Respectively.

Therefore, in the process of passing the metal tip of the syringe filter cap and the front of the housing through the rubber stopper of the vial of another conventional example, the leakage protrusion formed between the rear end of the metal tip and the front end of the housing is caught by the rubber stopper holes, There is a problem that the tip of the housing does not penetrate well in the process of passing the syringe filter cap through the rubber stopper of the vial.

9, a syringe filter cap according to another embodiment of the present invention is provided with a resistance step 301 for generating resistance of fluid at the time of suction of the injection liquid, The resistance step 302 causing resistance of the fluid at the time of suction of the injection liquid is formed in the front end of the injector 104 so that the suction performance of the injection solution is deteriorated due to the resistance steps 301 and 302 I also had problems.
