Description

니들의 교체가 필요 없는 주사기의 전환장치{Switching apparatus of syringe without change of needle}Switching apparatus of syringe without change of needle}

본 발명은 주사기의 전환장치에 관한 것으로서, 특히 주사기의 필터니들과 투여용니들을 교체하지 않고서도 용이하게 약물의 흡입 및 투여를 할 수 있도록 하는 니들의 교체가 필요 없는 주사기의 전환장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for switching a syringe, and more particularly, to a device for switching a syringe, which does not require replacement of a needle to easily inhale and administer a drug without replacing the filter needle and the administration needle of the syringe. .

일반적으로 주사기를 사용하여 유리앰플이나 바이알용기의 약물을 흡입하여 인체에 투여시 하나의 니들을 사용하여 왔다. 하지만 이러한 방식을 채택하게 되면 주사기 내로 약물 흡입시 유리앰플의 유리파편 또는 바이알용기의 고무파편과 같은 이물질이 주사기 내로 흡입되어 니들을 통해 그대로 인체에 유해한 이물질 등이 투여된다.In general, a needle has been used to inject a drug in a glass ampoule or vial container using a syringe and administer it to a human body. However, if this method is adopted, foreign substances, such as glass fragments of glass ampules or rubber fragments of vials, are sucked into the syringe when the drug is inhaled into the syringe, and foreign substances harmful to the human body are administered as they are through the needle.

이러한 문제점들을 해결하고자 근래에는 도 1에서와 같이 주사기(110)를 이용하여 유리앰플이나 바이알용기의 약물을 흡입시에는 내부에 필터(121)가 구비된 필터니들(120)을 사용하고, 필터니들(120)을 통해 약물의 유입이 완료되면 필터니들(120)을 분리한 후 투여용니들(130)을 사용하여 인체에 투여하고 있다.In order to solve these problems, in recent years, when inhaling a drug in a glass ampoule or vial container using a syringe 110 as shown in FIG. 1, a filter needle 120 having a filter 121 therein is used, and a filter needle. When the inflow of the drug is completed through 120, the filter needle 120 is separated and then administered to the human body using the administration needle 130.

하지만 상기 방식을 채택하게 되면 인체에 약물을 투여하게 되는 사용자(특히 의사, 간호사 등)가 두가지의 니들을 사용하여야 하므로 교체에 대한 번거로움이 발생하게 되고, 또한 필터니들(120)과 투여용니들(130)을 모두 구매하여 사용해야 하므로 경제적인 부담도 발생되며, 이러한 경제적인 부담은 다시 환자들에게 돌아오게 되는 문제점이 있었다.However, if the above method is adopted, the user (especially a doctor, a nurse, etc.) who administers the drug to the human body needs to use two needles, and thus, troublesome replacement occurs, and also the filter needle 120 and the needle for administration Since all 130 must be purchased and used, an economic burden is generated, and this economic burden has a problem of returning to the patients again.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 주사기를 이용한 약물흡입 및 약물투여시 필터니들과 투여용니들을 교체하지 않고서도 용이하게 약물의 흡입 및 투여를 할 수 있도록 하는 니들의 교체가 필요 없는 주사기의 전환장치를 제공하는데 그 목적이 있다.The present invention is to replace the needle to facilitate the inhalation and administration of the drug without replacing the filter needle and the administration needle during drug inhalation and drug administration using a syringe to solve the problems of the prior art as described above It is an object of the present invention to provide a switching device for a syringe which is not necessary.

상기와 같은 목적을 실현하기 위하여, 본 발명은 길이방향으로 관통공을 갖는 관체와, 관체의 전방에 관체의 직경보다 좁은 돌출 형태를 갖는 장착부가 연장 형성되고 관체의 내부에 피스톤이 구비되는 주사기본체와, 니들핀과 니들허브로 구성되어 주사기본체의 전방에 구비되는 니들로 구성되는 주사기의 관체와 니들핀 사이에 전환장치를 구성하되, 상기 전환장치는; 상기 관체와 니들핀을 연통되게 하며, 원형단면을 갖는 상부 개방형태의 수용부가 형성되는 고정체를 마련하고, 상기 고정체의 수용부에 회전 가능하게 삽입되며 일방향으로 투여용통로가 관통 형성되고 투여용통로에 엇갈리게 투여용통로의 상부측 또는 하부측으로 흡입용통로가 관통 형성되는 전환부와, 전환부의 상부측에 형성되어 외부측에서 회전 가능토록 형성되는 회전용손잡이부로 구성되어지되, 상기 투여용통로 및 흡입용통로는 각각의 유입측 및 배출측이 모두 전환부 상의 수평선상에 위치되고, 흡입용통로의 중심측은 투여용통로의 하부측을 지나도록 형성되게 하여 중심측에 수거공간이 형성되는 회전체를 마련하며, 상기 회전체의 흡입용통로 내에 고정 구비되는 필터를 마련하여서 이루어짐을 특징으로 하는 니들의 교체가 필요 없는 주사기의 전환장치를 제공한다.In order to achieve the above object, the present invention is a syringe body in which a tubular body having a through hole in the longitudinal direction, and a mounting portion having a projecting shape narrower than the diameter of the tubular body in front of the tubular body is extended and a piston is provided in the tubular body. And a switching device configured between the needle body and the needle pin of the syringe including a needle pin and a needle hub, the needle being provided in front of the syringe body, wherein the switching device comprises: The tube and the needle pin to communicate with each other, to provide a fixed body is formed in the upper open receiving portion having a circular cross-section, rotatably inserted into the receiving portion of the fixed body and the passage for administration in one direction is formed through the administration It is composed of a switching portion formed through the suction passage to the upper side or the lower side of the administration passage staggered in the passage, and a rotating handle portion formed on the upper side of the switching portion to be rotatable from the outside side, The passage and the suction passage are each inlet and discharge side is located on the horizontal line on the switch, the center side of the suction passage is formed to pass through the lower side of the administration passage to form a collection space in the center side There is no need to replace the needle, characterized in that provided by the rotating body, by providing a filter fixedly provided in the suction passage of the rotating body It provides a switching device of the syringe.

이와 같이 이루어지는 본 발명에 의한 니들의 교체가 필요 없는 주사기의 전환장치는 주사기본체와 니들 사이, 주사기본체 또는 니들의 니들허브에 장착하여 간단한 전환작동으로 약물의 흡입 및 투여를 할 수 있는 필터가 부착된 전환장치를 구비함으로써 필터니들 및 투여용니들을 교체하는 불편함을 해소함은 물론, 그에 따르는 비용절감을 할 수 있게 된다.The needle switching device according to the present invention does not require replacement of the needle, which is attached to the needle body between the syringe body and the needle, the syringe body or the needle hub of the needle is attached to the filter for inhalation and administration of the drug with a simple switching operation. It is possible to eliminate the inconvenience of replacing the filter needle and the dosing needle, as well as to reduce the cost.

또한 니들의 교체 없이 간단한 작동으로 환자에게 정제된 약물을 투여할 수 있게 되며, 이에 따라 니들 교체에 따른 환자의 감염방지와 의료인의 업무능률을 높일 수 있는 이점이 있다.In addition, it is possible to administer the purified drug to the patient by a simple operation without replacing the needle, and thus there is an advantage that can prevent the infection of the patient and increase the work efficiency of medical personnel due to the needle replacement.
