Description

양방향 주사기{Bidirectional Syringe}Bidirectional Syringe

본 발명은 약제와 용해액(수액)을 혼합하기 위한 양방향 주사기에 관한 것으로 상세하게는 약제 용기와 용해액을 한번에 연결하여 수액의 이동과 용해된 약액의 이동이 체결된 주사기에서 한꺼번에 이루어 질 수 있는 양방향 주사기에 관한 것이다. The present invention relates to a bidirectional syringe for mixing a medicament and a dissolving liquid (liquid). More particularly, the present invention relates to a bidirectional syringe for mixing a medicament container and a dissolving liquid at one time, To a bidirectional syringe.

무균분말주사제를 점적주사로 사용하기 위해 무균분말의 용해와 다시 점적용액으로의 희석이 필요하다. 다시 말해, 무균분말을 희석하기 위해 1차로 점적용액(예; 생리식염주사액, 포도당주사액, 주사용수 등)을 주사기로 투침하여 일정량의 용액을 분체하고, 용액이 분체된 주사기를 점적용액으로부터 제거한 후 다시 무균분말이 담겨있는 용기(예; 바이알 등)에 투입하여 분체된 용액을 주입하여 용해시켜서 1차 용액으로 만든다. 분말의 용해가 완료되면 다시 주사기를 투침하여 1차 용액을 분체하고, 이후 분체된 1차 용액을 다시 점적용액(예; 생리식염주사액, 포도당 주사액, 주사용수 등)에 투침하여 분체된 용액을 점적용액으로 이동시켜 최종적으로 희석시킨 후 사용할 수 있다. In order to use aseptic powder injections, it is necessary to dissolve sterile powders and dilute them into a multi-point solution. In other words, in order to dilute sterile powder, a certain amount of solution is pulverized by first injecting a drop solution (eg, physiological saline solution, glucose solution, injection water, etc.) with a syringe, The solution is then poured into a container containing sterile powders (eg, vials) to dissolve and inject the powdered solution into a primary solution. After the dissolution of the powder is completed, the primary solution is sprayed through the syringe again, and then the primary solution is sprayed into the drip solution (eg, physiological saline solution, glucose injection solution, injection water, etc.) Solution, and finally diluted.

본 발명은 무균분말주사제의 점적주사로 사용 시, 분말상태의 약을 용액으로 희석시키고, 다시 점적주사 용액에 희석시키는 과정에서 주사기의 분리없이 한번에 조제하고, 희석할 수 있도록하는 양방향 주사기를 제공하는 것을 목적으로 한다. The present invention provides a bidirectional syringe that can be dispensed and diluted in a single step without diluting the syringe in the process of diluting the powdered medicament into a solution and diluting it into a multi-point injection solution when used in a dummy injection of sterile powdered injection .

본 발명 양방향 주사기는 주사기 본체에 주입관 2개를 포함하고 있어 양방향의 용기에서 약액이 소통할 수 있도록 한다. 약액의 소통을 위하여 방향전환 레버를 좌, 우로 움직이면 방향전환 주입관이 있어서 원하는 방향으로 선택적으로 이동시킬 수 있다. The bidirectional syringe of the present invention includes two injection tubes in the main body of the syringe so that the chemical solution can communicate with the bidirectional container. When the direction changing lever is moved to the left or right to communicate the chemical liquid, the direction changing injection pipe can be selectively moved in a desired direction.

방향전환부재에는 탄성력을 갖는 고무재질의 씰링부재를 포함하고 있어 방향전환시 방향전환 주입관으로 부터의 누액이 방지될 수 있도록 한다. The direction changing member includes a rubber sealing member having an elastic force so that leakage from the direction changing injection pipe can be prevented at the time of changing direction.

또한, 방향전환부재 고정부를 통하여 방향전환부재를 좌, 우 이동시 상하로 이탈되지 않도록 고정해주는 고정부를 포함하고 있다. And a fixing portion for fixing the direction changing member so as not to be separated vertically when the direction changing member is moved left and right through the direction changing member fixing portion.

본 발명은 무균분말주사제를 점적주사로 사용할 때와 같이 분말상태의 약을 용해시키고, 다시 수액으로 희석시키고 하는 동작이 반복적으로 이루어진다. 해당 주사제는 반복적인 용액의 용해와 희석의 행위로 인해 주사기 바늘의 외부 접촉횟수 증가가 발생할 수 있고 이로 인해, 무균교차오염의 위험성이 발생할 수 있다. 때문에 양방향 주사기는 용액의 조제와 희석을 위한 반복적인 동작에도 주사기와 약액용기의 분리없이 용액의 희석과 이동이 가능하기 때문에 무균오염에 대한 위험을 사전에 예방할 수 있다. The present invention repeatedly performs an operation of dissolving a drug in a powder state and diluting it again with a liquid as in the case of using a sterile powder injected drug by drip injection. The injection agent may cause an increase in the number of external contacts of the syringe needle due to repeated dissolution and dilution of the solution, which may lead to the risk of sterile cross-contamination. Therefore, the bidirectional syringe can prevent the risk of aseptic contamination because the solution can be diluted and moved without repeated separation of the syringe and the chemical container, even for repetitive operations for preparation and dilution of the solution.

The syringe body 10 includes the direction changing support 13 so that the injection tube 11 and the syringe direction switching injection tube 23 are exactly aligned at the time of changing direction so that communication can be performed without leakage. Further, the direction changing member fixing portion 14 can prevent the direction changing member 20 from being separated from the syringe body 10.

방향전환부재(20)는 주사기의 방향전환 주입관(23)을 통하여 약액의 소통이 이루어질 수 있도록 하고, 방향전환레버(24)를 좌, 우로 움직임으로써 원하는 방향으로 선택적으로 방향전환을 할 수 있다. 방향전환부 몸체(22)는 주입부재(30)을 지지하는 역할을 하고, 방향전환레버(24)에서 지시된 방향으로 주사기 방향전환 주입관(23)이 움직일 수 있도록 연결하는 지지대 역할을 하게 된다. 또한 방향전환부재(20)에는 자체 탄성력을 갖는 고무재질의 링 형태로 형성되는 방향전환의 씰링부재(21)를 포함하고 있어 기밀이 유지되고, 주사기 방향전환 주입관(23)과 주입관(11)으로 약액이 소통할 때, 누액이 방지될 수 있도록 한다. The direction changing member 20 can communicate the chemical liquid through the direction switching injection pipe 23 of the syringe and selectively turn the direction changing lever 24 in a desired direction by moving the direction changing lever 24 left and right . The direction changing unit body 22 serves to support the injection member 30 and serves as a support for connecting the syringe direction switching injection pipe 23 in a direction indicated by the direction switching lever 24 . In addition, the direction changing member 20 includes a sealing member 21 for changing direction, which is formed in the form of a ring made of a rubber material having a self-elastic force. Hence, airtightness is maintained and the syringe direction switching injection tube 23 and the injection tube 11 ), So that leakage can be prevented when the chemical liquid communicates.

주입부재(30)의 방향전환부재 몸체 내부(31)에는 수액이나 용해된 약액이 담길 수 있는 형태이며, 주입부의 씰링부재(32)는 방향전환부재 몸체 내부(31)에 담겨진 약액이 누액되지 않도록 자체 탄성력을 갖는 고무재질로 제작되며 링 형태로 형성되어 방향전화부재 몸체 내부(31)에 씰링부재가 밀착 상태를 유지하면서 기밀을 유지할 수 있도록 한다. The sealing member 32 of the injection part is formed in such a manner that the chemical solution contained in the direction changing member body 31 is not leaked Is formed of a rubber material having a self-elasticity and is formed into a ring shape so that the sealing member can be kept in close contact with the inside of the direction dial phone member body (31) to maintain airtightness.

주입부재(30)에는 압력을 가해 약액이 이동할 수 있도록 하기 위해 가압부재(34)를 포함하고 있어 약액의 소통이 이루어 질 수 있도록 한다. The injection member 30 includes a pressing member 34 for allowing the chemical liquid to move by applying pressure, so that the chemical liquid can be communicated.
