Description
본 발명은 주사기용 필터캡에 관한 것으로, 보다 상세하게는 주사액 유입로의 후방에 직경이 확장된 압력 저감홈부를 형성하고 압력 저감홈부의 후방에 필터를 내장시켜, 주사기를 통해 주사액의 흡입하는 과정에서 필터를 통과하는 주사액의 흡입 압력을 줄임에 따라, 주사기를 통해 주사액을 흡입하는 과정에서 적은 힘으로도 주사액을 흡입할 수 있도록 하는 주사기용 필터캡에 관한 것이다.The present invention relates to a filter cap for a syringe, and more particularly, to form a pressure reducing groove having an extended diameter at the rear of the injection liquid inlet path, and to incorporate a filter at the rear of the pressure reducing groove to suck the injection liquid through the syringe. By reducing the suction pressure of the injection liquid passing through the filter in, it relates to a filter cap for the syringe to inhale the injection with a small force in the process of inhaling the injection through the syringe.
일반적으로 주사기는 체내에 주사액을 주사하는 기구로, 앰플이나 바이알과 같은 용기에 담겨진 주사액을 실린더의 내부로 빨아드려 채운 후 체내에 주입하는 것이다. 이러한 주사기는 주사바늘이 결합되어 약액이 수용되는 실린더와, 상기 실린더내에 축방향을 따라 전진 및 후퇴 가능하게 구비되는 플런저로 구성된다. In general, a syringe is a device for injecting injection liquid into the body, and the injection liquid contained in a container such as an ampoule or vial is sucked into the cylinder and filled and then injected into the body. Such a syringe is composed of a cylinder in which a needle is coupled to receive a chemical liquid, and a plunger provided in the cylinder so as to be moved forward and backward along the axial direction.
그리고 주사기를 사용하여 인체에 주사액을 주입할 경우에는, 실린더의 주사바늘을 바이알의 고무뚜껑에 관통시키거나 앰플에 부러진 입구에 삽입시킨 후, 주사액을 실린더의 내부에 채운 후 인체의 주사 놓을 부위에 찔러 체내에 주사액을 주입하였다. In case of injecting the injection liquid into the human body using a syringe, insert the needle of the cylinder through the rubber lid of the vial or insert it into the inlet broken in the ampoule, and then fill the injection into the cylinder and place it on the injection site of the human body. The needle was injected into the body.
그러나 상기와 같이 주사기를 사용하여 바이알에 채워진 주사액을 주사기의 실린더로 채우는 과정에서 주사기의 주사바늘을 바이알의 고무마개에 관통시키는 경우에는, 고무마개의 일부가 주사바늘의 관통순간에 떨어져 나가 바이알의 내부에 투입되어 주사액에 혼입됨에 따라, 주사기의 실린더로 이물질이 유입됨으로써 인체에 치명적인 부작용을 유발하는 문제점이 있었다. However, in the case where the syringe needle is penetrated into the rubber stopper of the vial in the process of filling the syringe with a cylinder of the syringe using the syringe as described above, a portion of the rubber stopper falls off at the moment of penetration of the needle and the inside of the vial. As it is injected into the injection solution, foreign matters are introduced into the cylinder of the syringe, which causes a fatal side effect.
이에, 상기와 같은 문제점을 해소하고자 종래에는 주사기의 실린더의 내부로 이물질이 유입되는 것을 방지할 수 있도록 여러 종류의 주사기용 필터캡이 알려져 있는데, 먼저, 그 일예로 대한민국 특허등록 제1243396호의 "주사용 필터캡"(이하, "종래의 제1 실시예의 주사기용 필터캡"이라 한다.)를 살펴보면 다음과 같다.Thus, in order to solve the above problems, conventionally, several types of filter caps for syringes are known to prevent foreign substances from entering into the cylinder of the syringe. First, as an example, "Note of Korean Patent Registration No. 1243533" Filter cap "(hereinafter, referred to as" filter cap for syringe of conventional first embodiment ") is as follows.
종래의 제1 실시예의 주사기용 필터캡은 도 6에 도시된 바와 같이, 내부에 주사액유입로(704)가 관통되고, 주사바늘이 삽입될 수 있도록 주사액유입로(704)에 연통되게 연결된 주사바늘삽입로(705)가 관통되고, 주사바늘이 밀착되어 음압이 형성될 수 있도록 주사바늘삽입로(705)에 연통되게 연결된 주사바늘밀착로(706)가 관통된 하우징, 상기 주사액유입로(704)로 유입되는 주사액을 여과시킬 수 있도록 상기 주사액유입로(704)와 주사바늘삽입로(705)의 연통부분에 용융접착으로 장착되는 필터(701)를 포함한다. 그리고 상기 주사액 유입로(704)와 주사바늘삽입로(705)는 앰플삽입관(702 : 이하, "삽입관"이라 한다.)의 내부에 형성되는 것이다. As shown in FIG. 6, the syringe cap of the first embodiment of the prior art has an
상기 필터(701)는 주사액유입로(704)와 주사바늘삽입로(705)의 연통부분에 용융접착으로 고정되는 것이다. 그리고 상기 필터는 5㎛ 이하의 투과성을 갖는 필터를 사용하였다. 아울러 상기 필터(701)는 화학적으로 안정하여 주사액과 반응하지 않고 용융접착이 가능한 다양한 재료를 통해 구비될 수 있다. 특히 상기 주사액유입로의 내경은 상기 필터를 융착을 통해 고정할 수 있도록 상기 주사바늘삽입로(705)의 내경보다 더 크게 형성되어 있는 것이다. The
그런데, 상기와 같이 구성된 종래의 제1 실시예의 주사기용 필터캡은 다음과 같은 문제점을 가지고 있다. By the way, the filter cap for a syringe of the conventional 1st Example comprised as mentioned above has the following problems.
먼저, 종래의 일 실시예의 주사기용 필터캡은 삽입관의 내부 전방에 필터를 장착하기 위하여 직경이 확장되는 주사액 유입로가 형성됨으로써, 삽입관의 외경이 커짐에 따라 삽입관이 바이알의 고무마개에 잘 관통되지 못하는 문제점을 가지고 있었다.First, the syringe cap of the conventional embodiment is formed with an injection fluid inflow path extending in diameter to mount the filter in the front of the insertion tube, the insertion tube is attached to the rubber stopper of the vial as the outer diameter of the insertion tube increases Had a problem that can not penetrate well.
좀 더 구체적으로 설명하면, 종래의 일 실시예의 주사기용 필터캡은 필터의 흡입 직경에 따라 주사액의 흡입 성능이 결정되는데, 필터의 흡입 직경이 클수록 주사액의 흡입 성능이 향상되고, 반대로 필터의 흡입 직경이 작아질수록 주사액의 흡입 성능이 저하된다. In more detail, the suction cap of the injection liquid is determined according to the suction diameter of the filter of the conventional embodiment, and the suction diameter of the filter improves as the suction diameter of the filter increases, and conversely, the suction diameter of the filter The smaller the value, the lower the suction performance of the injection solution.
따라서 종래의 일 실시예의 주사기용 필터캡은 주사액의 흡입이 잘되게 할 수 있도록 필터의 흡입 직경을 확장시켜야 함으로써, 부득이 필터가 장착되는 주사액 유입로를 내경을 확장시켜야 한다. 그러므로 상술한 바와 같이, 주사액 유입로의 확장으로 인하여 삽입관의 외경을 필수적으로 확장시켜야 한다. 따라서 종래의 일 실시예의 주사기용 필터캡의 삽입관 외경은 합성수지재의 성형 특징상 적은 직경으로 형성할 수 없어 최소 3mm이상이 됨으로써, 종래의 일 실시예의 주사기용 필터캡의 삽입관을 바이알의 고무마개에 관통시킬 경우에는 삽입관이 잘 관통되지 않아 사용상에 많은 불편함이 있는 문제점을 가지고 있었다.Therefore, the filter cap for a syringe of a conventional embodiment has to expand the suction diameter of the filter so that the suction of the injection liquid can be facilitated, thereby inevitably expanding the inner diameter of the injection liquid inlet in which the filter is mounted. Therefore, as described above, the outer diameter of the insertion tube must be essentially enlarged due to the expansion of the injection liquid inflow path. Therefore, the outer diameter of the insertion tube of the filter cap for a syringe of the conventional embodiment can not be formed in a small diameter due to the molding characteristics of the synthetic resin material is at least 3mm or more, so that the insertion tube of the filter cap for syringes of the conventional embodiment is a rubber stopper of the vial In the case of penetrating into the insertion tube was not penetrating well, there was a problem that there is a lot of inconvenience in use.
또한 종래의 제1 실시예의 주사기용 필터캡은 도 8에 도시된 바와 같이, 주사바늘삽입로의 전단에는 주사액의 흡입시 유체의 저항을 일으키는 저항단차(800)가 형성됨으로써, 주사액을 주사기에서 흡입하는 과정에서 상기 저항단차(800)로 인하여 주사액의 흡입 성능이 저하되어 부득이 한손만이 아닌 두손으로 주사기의 몸체를 잡고 손잡이를 당겨야 하는 문제점도 가지고 있었다.In addition, as shown in FIG. 8, the filter cap for a syringe according to the first embodiment of the present invention is formed at the front end of the needle insertion path by forming a
한편, 종래의 다른 실시예의 주사기용 필터캡으로 대한민국 특허등록 제1460465호의 "금속팁을 구비한 바이알용 주사기 필터캡"(이하,"종래의 제2 실시예의 주사기 필터캡"이라 한다.)을 살펴보면 다음과 같다. On the other hand, as a filter cap for the syringe of another conventional embodiment of the Republic of Korea Patent No. 1460465 "Valentine syringe filter cap with a metal tip" (hereinafter, referred to as "the conventional syringe filter cap of the second embodiment") As follows.
종래의 제2 실시예의 주사기 필터캡은 도 7에 도시된 바와 같이, 하우징(100)의 전방에 구비되는 주사바늘삽입로(104)의 전방에는 일단부가 용융접착으로 부착된 필터(105)가 구비되는 것이다. 그리고 금속팁(200)은 관 형상의 구성되는 것으로, 상기 주사바늘삽입로(104)의 선단에 돌출되게 형성되는 관 형상의 주사액 유입구(106)의 외주면에 삽입되어 고정되는 것이다. 따라서, 상기 필터(105)는 주사액 유입구(106)의 내부 후방인 주사바늘삽입로(104)의 선단에 부착되어 고정되는 것이다. As shown in FIG. 7, the syringe filter cap according to the second embodiment of the present invention includes a
아울러 상기 금속팁(200)의 내주면과 주사액 유입구(106) 외주면은 접착제(B)로 부착되어 있는 것이다.In addition, the inner circumferential surface of the
그런데, 상기와 같이 구성된 종래의 제2 실시예의 주사기 필터캡은, 전술한 제1 실시예의 주사기용 필터캡과 마찬가지로, 하우징의 선단인 주사액 유입구의 내부 후방에 필터를 장착하기 위하여 주사액 유입구의 직경이 확장되게 형성됨으로써, 주사액 유입구가 외경이 커지고 주사액 유입구에 삽입되는 금속팁의 외경도 확장됨에 따라, 금속팁이 바이알의 고무마개에 잘 관통되지 않는 문제점을 가지고 있었다. However, the syringe filter cap of the conventional second embodiment configured as described above has the diameter of the injection liquid inlet in order to mount the filter inside the injection liquid inlet which is the front end of the housing, similarly to the filter cap for the syringe of the first embodiment described above. As it is formed to be expanded, as the injection inlet has an outer diameter larger and the outer diameter of the metal tip inserted into the injection inlet also expands, the metal tip does not penetrate the rubber stopper of the vial well.
또한, 종래의 다른 실시예의 주사기 필터캡은 금속팁을 고정할 경우에는, 도 9에 도시된 바와 같이, 먼저, 주사액 유입구(106)의 외주면에 접착제(B)를 바른 다음 주사액 유입구의 외주면에 금속팁(200)을 삽입하는 과정을 통해 금속팁(200)을 고정한다. 그런데, 이와 같이 금속팁(200)을 고정하는 과정에서 접착제(B)가 금속팁(200)의 후단부와 주사바늘삽입로(104)의 전단부의 사이에서 외부로 누출되어 누출돌기(300)를 형성하게 된다. In addition, when fixing the metal tip of the conventional syringe filter cap, as shown in Figure 9, first, the adhesive (B) is applied to the outer circumferential surface of the injection
그러므로 종래의 다른 실시예의 주사기 필터캡의 금속팁과 하우징의 전방을 바이알의 고무마개에 관통시키는 과정에서 금속팁의 후단부와 하우징의 전단부의 사이에 형성된 누출돌기가 고무마개의 관통홀에 걸리게 됨으로써, 주사기 필터캡을 바이알의 고무마개에 관통시키는 과정에서 하우징의 선단이 잘 관통되지 않는 문제점도 가지고 있었다. Therefore, in the process of penetrating the front end of the metal tip of the syringe filter cap and the housing of the vial through the rubber stopper of the vial of another embodiment of the prior art, the leakage protrusion formed between the rear end of the metal tip and the front end of the housing is caught by the through hole of the rubber stopper, In the process of penetrating the syringe filter cap through the rubber stopper of the vial also had a problem that the tip of the housing does not penetrate well.
또한, 종래의 다른 실시예의 주사기 필터캡은 도 9에 도시된 바와 같이, 주사액 유입구(106)의 전단에는 주사액의 흡입시 유체의 저항을 일으키는 저항 단차(301)가 형성되고, 주사바늘삽입로(104)의 전단에도 주사액의 흡입시 유체의 저항을 일으키는 저항단차(302)가 형성됨으로써, 주사액을 주사기에서 흡입하는 과정에서 상기 저항단차(301)(302)들로 인하여 주사액의 흡입 성능이 저하되는 문제점도 가지고 있었다.In addition, the syringe filter cap of another conventional embodiment, as shown in Figure 9, the front end of the injection
이에, 상기와 같은 종래의 일 실시예의 주사기용 필터캡과 다른 실시예의 주사기용 필터캠의 제반 문제점을 해소할 수 있도록, 본 출원인은 대한민국 특허출원 제 2016-5005호의 "주사기용 필터캡 및 그 제조방법"(이하, 본 출원인이 기 출원한 주사기용 필터캡을 "종래의 제3 실시예의 주사기용 필터캡"이라 한다.)을 살펴보면 다음과 같다. Thus, in order to solve the problems of the filter cap for the syringe of the conventional embodiment and the syringe filter cam of another embodiment as described above, the applicant of the Korean Patent Application No. 2016-5005 "injector filter cap and its manufacture Method "(Hereinafter, the filter cap for a syringe previously applied by the present applicant is referred to as" filter cap for syringe of the conventional third embodiment ").
종래의 제3 실시예의 주사기용 필터캡은 내부의 전방에는 주사바늘 삽입로(101)가 형성되고 주사바늘 삽입로(101)의 후방에는 주사바늘허브 삽입로(102)가 형성되는 하우징(100)과; 상기 주사바늘 삽입로(11)의 전방에 주사바늘 삽입로(11)의 직경보다 직경이 확장되게 형성되고 전방이 개방되는 금속팁 삽입로(200)와; 상기 금속팁 삽입로(200)의 후방단부에 초음파 접착으로 부착되는 필터(300)와; 상기 금속팁 삽입로(200)에 삽입되어 접착제(B)로 고정되고 전방 단부에 관통 경사부가 형성되며 내부에는 주사액 유입로(401)가 형성되는 관 형상의 금속팁(400)을 포함한다.The filter cap for a syringe according to the third embodiment of the prior art has a
그리고 상기 주사액 유입로(41)의 내경과 상기 주사바늘 삽입로(11)의 내경은 동일하게 형성되는 것이다. The inner diameter of the injection
그런데 상기와 같이 구성된 종래의 제3 실시예의 주사기용 필터캡은 주사액의 흡입하는 과정에서, 주사액이 통과되는 주사액 유입로(401)의 내경과 상기 주사바늘 삽입로(101)의 내경이 동일하게 형성됨에 따라, 주사액 유입로(401)와 주사바늘 삽입로(101)의 사이에 구비된 필터로 주사액이 통과되면서 흡입 압력이 강하게 걸리게 됨으로써 주사액의 흡입시 많은 힘이 들게 되는 문제점을 가지고 있었다.By the way, the filter cap for a syringe according to the third embodiment of the related art configured as described above has an inner diameter of the injection
