Abstract

The present invention relates to an adaptor having an integrated filter and a syringe having the same. An injectable solution inlet hole or an injectable solution outlet hole is configured to be selectively interconnected to an injectable solution movement pipe by a simple operation of rotating a valve member. By installing a filter in a front end portion of the injectable solution outlet hole, the injectable solution is inhaled without passing through the filter when inhaling the injectable solution into the syringe. The injectable solution is discharged through the injectable solution outlet hole after filtering foreign substances contained in the injectable solution when administering the injectable solution, which has been inhaled into the syringe, to a human body.

Description

A syringe with a filter < RTI ID = 0.0 >

The present invention relates to a syringe having a filter. More particularly, the present invention relates to a syringe having a filter, and more particularly, to an injection fluid inlet hole or an injection fluid outlet hole by a simple operation of rotating a valve member, When the injection liquid is sucked into the inside of the syringe, the injection liquid is sucked without passing through the filter. When the injection liquid sucked into the syringe is administered to the human body, the foreign substance contained in the injection liquid is filtered through the filter, To a syringe equipped with a filter to flow out.

In general, injections administered by a syringe to a patient are placed in an ampoule made of glass or a vial having a rubber stopper applied to a glass bottle. The injections in the ampoules or vials are administered to the patient using a syringe. The glass pieces generated by opening the ampoule or the rubber pieces generated from the rubber stopper of the vial are introduced into the syringe.

Therefore, when injections are administered through a syringe, glass fragments or rubber fragments may be administered to patients to cause complications. In particular, there is a fear that phlebitis is induced by intravenous administration, Not only are there problems that cause necrosis of body tissues, but also can lead to cancer in severe cases.

Recently, the use of a syringe filter is recommended to prevent glass fragments or rubber pieces from being administered to a patient, and various syringe filter structures for providing user convenience have been developed, The filter structure is disclosed in Korean Patent Registration No. 10-981586 (hereinafter referred to as "prior patent").

In the prior art, before the injection liquid is sucked into the syringe, the injection liquid is sucked while the filter tip having the filter is embedded in the neck portion of the cylinder, so that the glass fragments contained in the injection liquid are pre-filtered by the filter When the injector is to be sucked into the inside of the syringe, the filter tip is inserted. When the injector injector is administered to the patient, the filter tip is removed. After the new syringe tip is connected to the syringe, Therefore, there is a problem in that the inhalation and administration process of the injection solution is cumbersome, and in the process of sucking the injection solution into the inside of the syringe, the filter pressure applied by the filter hinders smooth suction of the injection solution.
