Description
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
The
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. As the outer diameter of the insertion tube becomes larger, It had a problem that it could not penetrate well.
More specifically, the suction performance of the injection liquid is determined according to the suction diameter of the filter in the syringe filter cap of the prior art embodiment. The larger the suction diameter of the filter is, the more the suction performance of the injection liquid is improved. On the other hand, The suction performance of the injection liquid deteriorates.
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
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.
9, the syringe filter cap according to another embodiment of the present invention is provided with a
In addition, the inner circumferential surface of the
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
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
