Description

필터를 가진 주사기용 바늘 뭉치와 그 제조 방법{Needle member for syringe including filter and the manufacturing method thereof}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a needle bundle for a syringe having a filter,

본 발명은 필터를 가진 주사기용 바늘 취부체와 그 제조 방법에 관한 것이다The present invention relates to a needle attachment body for a syringe having a filter and a method of manufacturing the same

일반의 주사기는, 내부에 주사액이 저장될 수 있도록 공간부가 형성된 원통형의 실린더와 실린더에 설치된 피스톤과 실린더의 전방에 형성된 네크부와 네크부에 결합되는 바늘뭉치로 구성된다. A general syringe includes a cylindrical cylinder having a space formed therein for storing an injection liquid therein, a piston provided on the cylinder, a neck formed on the front of the cylinder, and a needle bundle coupled to the neck.

이러한 구성의 주사기는 주사액이 수용된 앰플(Ampoule)의 상부를 깨뜨려 개봉하고, 개봉된 부분으로 주사바늘을 인입한 후 피스톤을 후퇴시켜 주사액이 실린더의 내부로 흡입되게 한다.The syringe having such a configuration breaks the upper portion of the ampoule containing the injection liquid, draws the injection needle into the opened portion, and then retracts the piston so that the injection liquid is sucked into the cylinder.

이러한 주사액 흡입 및 투입과정에서 앰플 상부를 깨뜨려 개봉하게 되면 유리파편이 비산되면서 When the upper part of the ampoule is opened by opening and closing the injection liquid, the glass fragments are scattered

그 일부가 앰플의 내부로 들어가고, 앰플의 내부로 들어간 미세 유리파편은 주사기로 흡입되어 환자에게 주입되어 치명적인 악영향을 미치게 된다.Part of it enters the inside of the ampoule, and micro-glass fragments that enter the inside of the ampoule are sucked into the syringe and injected into the patient, which has a catastrophic adverse effect.

이러한 문제점을 개선하기 위해, 국내특허등록 제10-981586호 주사기용 안전 필터 팁은 바늘뭉치의 통체 내부에 걸림 턱을 돌출형성하고, 걸림턱에 필터를 설치하고, 필터의 후면에 부싱을 억지끼움 맞춤하여 부싱이 필터를 걸림턱에 고정하도록 구성된 바늘 뭉치를 제공하였다.   In order to solve such a problem, a safety filter tip for a syringe is disclosed in Korean Patent Registration No. 10-981586, in which a catching jaw is protruded inside a cylinder of a needle bundle, a filter is installed in a catching jaw, And the bushing is provided with a needle bundle configured to fix the filter to the jaw.

그리고, 공개번호 제1020110087587호 주사기용 필터니들 및 그 제조 방법은 바늘뭉치 통체 내부에 걸림 턱을 돌출 형성하고 걸림턱에 필터를 설치한 후, 상기 필터 테두리와 대응되는 통체의 유로 내벽을 가열수단으로 가열 용융시켜 이 용융부분에 상기 필터를 열접착 방식으로 고정하는 것을 특징으로 하는 기술을 제공한다.  Open No. 1020110087587 A filter needle for a syringe and a method of manufacturing the same have a structure in which a catching jaw is protruded inside a needle bundle cylinder and a filter is provided on a jaw and then the inner wall of the channel corresponding to the filter rim is heated And the filter is heated and melted to fix the filter to the molten part by a heat bonding method.

그리고 등록특허 10-1165946호 및 10-1171150호는, 상기의 발명들이 주사기의 내부로 주사액을 흡입할 때는 상기의 바늘 뭉치를 끼운 채 흡입하고, 주사기의 주사액을 환자에게 투여할 때는 필터가 설치된 바늘 뭉치를 제거하고, 새로운 바늘 뭉치를 주사기에 결합한 후 주사액을 투여해야 하므로, 주사액의 흡입 및 투여과정이 번거롭고, 주사액을 주사기의 내부로 흡입하는 과정에서 필터에 의해 작용되는 필터압에 의해 주사액의 원활한 흡입을 방해하여 사용성을 떨어뜨린다고 하면서, 주사기로 주사액을 흡입할 때는 필터압이 작용하지 않도록 하여 주사액의 흡입성을 용이하게 하는 반면, 주사기 내의 주사액을 인체에 투여할 때는 주사액에 포함된 이물질을 여과할 수 있도록 함으로써 주사액의 흡입성 향상 및 필터링 효과를 동시에 수득할 수 있는 주사기용 필터부재를 제공한다고 한다. 그러나, 이는 그 구조가 복잡하여 제조가 곤란하며 필터의 설치 및 주사액의 통과 방향에 따른 통로 선택의 곤란성으로 인한 약액 누출의 염려가 있다.In addition, when the above-mentioned invention injects the injection liquid into the inside of the syringe, the above-mentioned needle bundles are inserted into the syringe while the injection solution of the syringe is injected into the patient. It is necessary to inject the injection solution after the bundle is removed and the new needle bundle is connected to the syringe. Therefore, the process of inhalation and administration of the injection solution is troublesome, and the injection pressure of the injection solution When injecting an injection with a syringe, the filter pressure does not act to facilitate the inhalation of the injection. In contrast, when injecting the injection in a syringe into a human body, Filtration of the injected liquid can be achieved, thereby improving the inhalation property and the filtering effect of the injection liquid. Said to provide appointed the filter element. However, it is difficult to manufacture due to its complicated structure, and there is a fear of drug leakage due to the difficulty in selecting the passage depending on the installation direction of the filter and the direction of passage of the injection liquid.

또한, 특허제10-1178986호는 주사액을 주사기 안으로 주입할 때는 필터부재를 거치지 않고 주사액을 환자에게 주입할 때에 필터부재를 거치도록 함으로써 주사 과정이 간편하면서도 앰플의 유리입자가 환자에게 주입되지 않도록 하는 주사기용 안전 필터 및 이를 구비하는 주사기로, 주사기의 실린더 내부에서 넥크부에 접하여 조립되고, 하나 또는 그 이상의 제1 관통공 및 하나 또는 그 이상의 제2 관통공을 포함하는 가이드밸브와, 가요성 재질로 구성되어 실린더 내부로 주사액이 들어올 때는 가이드밸브의 제2 관통공을 개방시키고, 실린더에서 주사액이 나갈 때는 가이드밸브의 제2 관통공을 폐쇄시키는 밸브와, 가이드밸브에 부착되어 상기 제1 관통공을 덮는 필터부재를 구비한다. 본 발명에 따르면, 주사액을 빨아들이거나 주사를 놓을 때 필터를 꽂거나 제거하는 등의 별도의 동작이 필요 없으므로, 앰플의 유리입자가 환자에게 주입될 가능성을 제거하면서도 주사 과정이 간편하다고 한다.  In addition, Japanese Patent No. 10-1178986 discloses a method for injecting an injectable solution into a syringe without passing through a filter member, by passing the injected solution through a filter member, thereby simplifying the injection process and preventing the glass particles of the ampule from being injected into the patient A safety filter for a syringe and a syringe having the syringe, comprising: a guide valve assembled in a cylinder of a syringe in contact with a neck portion, the guide valve including one or more first through holes and one or more second through holes; A valve that opens the second through hole of the guide valve when the injection liquid enters the cylinder and closes the second through hole of the guide valve when the injection liquid flows out of the cylinder, As shown in Fig. According to the present invention, since the separate operation such as inserting or removing the filter is not required when the injection liquid is sucked or injected, the injection process is simplified while eliminating the possibility that the glass particles of the ampule are injected into the patient.

그런데 등록특허 10-1165946호 및 10-1171150호 그리고 특허제10-1178986호는 구조가 복잡하여 제조가 곤란하며, 작용 부전의 염려가 있는 결점이 있어 실용화가 곤란하다. 그리고, 상기 특허 제10-981586호 “주사기용 안전 필터 팁” 및 공개번호 제1020110087587호 “주사기용 필터니들 및 그 제조 방법”은 비록 주사액을 주입한 후, 필터가 설치된 바늘 뭉치를 버리고 다시 다른 바늘뭉치를 주사기에 끼워 주사하여야 하는 불편은 있으나, 제조가 용이하고 특히 작용 부전의 염려가 적은 장점이 있다.However, since the structures are complicated and difficult to manufacture, there are drawbacks that there is a fear of malfunction, and it is difficult to put them into practical use. The above-mentioned patent No. 10-981586 " Safety filter tip for a syringe " and Open No. 1020110087587 " A filter needle for a syringe and a manufacturing method thereof ", after throwing an injection, discard a bundle of needles, There is an inconvenience that the bundle should be injected through a syringe, but it is easy to manufacture, and there is a particular advantage in that there is less concern about a malfunction.

그러나, 상기 특허 제10-981586호 “주사기용 안전 필터 팁” 및 공개번호 제1020110087587호 “주사기용 필터니들 및 그 제조 방법”은 위와 같은 제조상의 용이성으로 인한 장점을 가진다 하더라도 주사액을 흡입하는 과정에서 흡입 압력으로 인하여 필터가 설치된 바늘뭉치의 통체 내부 걸림 턱으로부터 필터가 이탈하여 필터가 제 기능을 발휘하지 못하게 되는 염려가 있다.However, the above-mentioned patent No. 10-981586 " Safety filter tip for a syringe " and Publication No. 1020110087587 " Filter needle for a syringe and its manufacturing method " There is a fear that the filter may not be able to exert its function because the filter is detached from the inner jaw of the needle of the bundle of needles provided with the filter due to the suction pressure.

이에 본 발명은 바늘뭉치 통체 내부에 걸림 턱을 돌출 형성하고 걸림턱에 필터를 설치한 후, 상기 필터를 상기 걸림턱에 고정시켜서 되는 바늘 뭉치를 제공하므로서, 제조를 용이하게 하여 실용성을 확보하면서도, 걸림턱에 설치되는 필터가 주사기의 약액 흡입압력으로 걸림턱으로부터 이탈되지 아니하게 하는 안전한 바늘 뭉치를 제공하여야 한다는 과제를 해결하고자 한다.Accordingly, it is an object of the present invention to provide a needle bundle in which a catching jaw is formed to protrude in a needle bundle basket, a filter is installed in a catching jaw, and then the filter is fixed to the catching jaw, It is necessary to provide a safety needle bundle that prevents the filter provided on the stopping jaw from being detached from the stopping jaw by the chemical suction pressure of the syringe.

위와 같은 과제를 해결하기 위하여 본 발명은, 바늘뭉치 통체 내부에 걸림 턱을 돌출 형성하고, 걸림턱에 필터를 설치한 후, 상기 필터를 상기 걸림턱에 고정시켜서 되는 바늘 뭉치를 제공함에 있어서, 바늘뭉치의 통체를 바늘결합부재와 주사기결합부재로 구분형성시키고, 바늘결합부재의 통체는 상단플렌지를 가지며 내부에 걸림턱을 가지게 구성되고, 상기 걸림턱은 환형의 오목부를 가지게 하여, 오목부를 가지는 걸림턱에 필터를 설치하고, In order to solve the above-mentioned problems, the present invention provides a needle bundle in which a catching jaw is protruded inside a needle barrel cylinder, a filter is provided in a catching jaw, and then the filter is fixed to the catching jaw, Wherein the needle-engaging member has an upper flange and an engaging jaw, and the engaging jaw has an annular recessed portion, and the engaging jaw has a recess having a recessed portion, A filter is installed on the jaw,

주사기결합부재의 통체는 상기 바늘결합부재의 상단플렌지에 맞닿는 플렌지와 상기 바늘결합부재의 걸림턱에 맞닿는 하단턱을 가지며, 상기 하단턱에는 상기 걸림턱의 환형 오목부에 대응하는 환형의 돌출부를 가지며, 상기 플렌지에는 상기 바늘결합부재의 상단플렌지에 용융접착되게 하는 뾰족돌출부를 형성되게 하여서 되는, 필터를 가진 주사기용 바늘 뭉치와 이러한 바늘 뭉치를 제조하는 방법을 제공한다.Wherein the cylinder of the syringe-engaging member has a flange for abutting against the upper flange of the needle-engaging member and a lower step for abutting against the engaging projection of the needle-engaging member, and the lower step has an annular projection corresponding to the annular recess of the engaging jaw And a needle protrusion for allowing the flange to be melt-adhered to the upper flange of the needle coupling member, and a method for manufacturing such a needle bundle.

위와 같은 본 발명의 필터를 가진 주사기용 바늘 뭉치는, 비록 주사액을 흡입한 후, 버리고 다시 새로운 바늘뭉치를 주사기에 끼워 주사하여야 한다는 결점이 있다 하더라도, 그 제조가 용이하며, 제조비용이 비교적 적게 소요되는데다가, 약액의 흡입 시 필터가 필터시트인 돌출턱으로부터 이탈될 염려가 없는 장점이 있어, 제조와 사용에 적합한 필터를 가진 주사기용 바늘 뭉치를 제공할 수 있게 되는 효과가 있다.Although the needle bundle for a syringe having the above-described filter of the present invention is defective in that it is injected after inserting the injected solution and then injecting a new needle bundle into the syringe, it is easy to manufacture and the manufacturing cost is relatively low There is no fear that the filter will be released from the protruding jaw which is the filter sheet when the chemical liquid is sucked, and it is possible to provide a needle bundle for a syringe having a filter suitable for manufacture and use.
