Description

필터링과 주사가 동시에 가능한 일회용 주사기{syringe} The filtering and injectable simultaneously disposable syringe syringe {}

본 발명은 일회용 주사기에 관한 것으로, 특히 약액을 흡입할 경우 이물질을 필터링한 후 동시에 주사가 용이토록 한 일회용 주사기에 관한 것이다. The present invention relates to a disposable syringe, and more particularly when aspirating the drug solution after filtering the foreign matters at the same time on the yitorok a disposable syringe for the injections.

일반적으로 주사기는 감염환자에게 투여할 때 사용하는 것이어서 주사과정에서 2차 감염이 발생되는 것을 방지하기 위하여 주로 일회용 주사기가 사용되고, 이러한 1회용의 주사기는 액상과 분말을 혼합하거나 또는 액상만을 주입하게 되는데 이때 액상은 주로 유리나 플라스틱으로 제조된 앰플에 담겨져 있어 액상을 주사기로 빨아들이기 위하여는 앰플을 온픈할 경우에 유리가루나 플라스틱 기타 불순물가루가 액상과 동시에 빨려지게 됨으로서 이러한 것을 걸러주는 기능이 없어 결국 인체에 주사할 경우에 동시에 주사되어 짐으로서 많은 부작용이 우려된다는 것이다. In general, the syringe there is mainly disposable syringe is in use, the syringe of this one-time mixing or injection only the liquid of a liquid and the powder in order to prevent the secondary infection in the injection process geotyieoseo used occurs when administered to patients infected with the liquid phase by being be mainly're contained in the ampoule when onpeun of the ampoule to suck the liquid into the syringe glass Luna plastics and other impurities, the powder is sucked at the same time as the liquid in the manufacture of glass or plastic do not have the capability to filter out those that eventually humans are simultaneously scanned when scanning is concerned that many side effects as a burden.

따라서 최근에는 이러한 문제점을 해소하기 위하여 2개의 1회용주사기를 사용함으로서 비 경제적이라는 것이고 이러한 주사기의 소각을 위하여 더욱 많은 비용의 지출이 발생되는 것이다. Therefore, recently, that will not economical by using two single-use syringe in order to solve this problem becomes an expenditure of more costs for the incineration of such a syringe.

따라서 본 발명은 주사기의 간단한 구조개선으로 주사기에 약액을 충진시킬 때 이물질이 유입되는 것을 필터를 통하여 완벽하게 걸러낼 수 있도록 하면서도 약액을 충진시킨 상태에서 주사바늘의 교체없이 그대로 환자에게 주사함에도 불구하고 걸러낸 이물질이 환자에게 재투여되는 것을 방지토록 한 것이다. Accordingly, the present invention in spite injected as patients without replacing the yet to be filtered completely through the filter that the foreign matter is introduced when filling the drug solution in the syringe in a simple structure, improved of syringe needles in a state in which filling the drug solution one will ever prevent foreign matter from being filtered out re-administered to the patient.

이를 위하여 본 발명은 주사바늘과 일체로 형성되는 고정부재에 필터구조체를 내장하고, 상기 필터구조체는 양측으로 흡입구와 배출구를 형성하여 각각의 흡입구와 배출구가 체크밸브 구조로 일방향으로만 개방되어지도록 하여 흡입경로와 배출경로를 구분토록 하며, 상기 약액의 배출구에는 이물질의 배출방지를 위한 필터를 장착하여 필터에 의하여 걸러진 이물질이 주사기 내부에 잔류하면서 환자에게 투여되는 것을 방지토록 한 것이다. The present invention To this end, it incorporates a filter structure to the fixed member formed with a needle integral with, the filter structure and by forming the inlet and outlet at both sides so that the respective inlet and outlet is opened only in one direction to the check valve structure ever, and separate the suction path and the discharge path, the foreign matter discharge port is filtered by a filter equipped with a filter for preventing the discharge of the foreign matter in the drug solution to the ever prevented from being administered to a patient while remaining in the syringe.

따라서 본 발명은 약액을 흡입하고 배출하는 라인이 구분되므로 약액 배출시 이물질이 함께 투여될 우려가 없고, 이에 따라 주사바늘을 교체할 필요없이 약액을 흡입한 후 바로 주사가 가능하므로 편리할 뿐만 아니라, 위급환자에게 신속한 대응이 가능한 것이다. Thus, the present invention is not only convenient, but also because the intake of the chemical liquid, and so the line is division of discharged chemical liquid is no fear that administration with foreign matter when discharged, can be directly injected and then aspirating the chemical liquid without the need to replace the injection needle according to this, It is capable of rapid response to emergency patients.

또한, 주사기로 흡입한 약액에 미세한 이물질이 함유되어 있다 하더라도 배출구에 장착되어 있는 필터에 의하여 걸러져 실린더 내부에 잔류하므로 환자에게 약액을 주사시 이물질이 배출될 우려가 전혀 없으며, 보다 안전한 치료를 받을 수 있는 것이다. In addition, even if there is contained a fine foreign matter in the sucked drug solution with a syringe, so remaining in the by the filter placed in the exhaust port funneled cylinder not at all the fear that the foreign material during injection of the chemical solution to the patient discharge, may be a safer treatment that will.

이하 본 발명에 따른 바람직한 실시 예를 첨부한 도면을 참조하여 설명하면 다음과 같다. It will be described below with reference to the accompanying drawings a preferred embodiment according to the present invention.

본 발명은 도 1 및 도 2에 도시된 바와 같이 실린더(100)와 피스톤(110)으로 이루어진 주사기 본체에 주사바늘(200)을 고정부재(210)를 이용하여 조립토록 하는 것으로, 상기 고정부재(210)에는 흡입구(1a)와 배출구(1b)가 형성된 필터구조체(1)를 내장하고, 각각의 흡입구(1a)와 배출구(1b)가 각각 체크밸브 구조에 의하여 서로 역방향으로만 개방이 가능토록 한 것이다. That the ever present invention is assembled by using the holding member 210, the injection needle 200 in the syringe body consisting of a cylinder 100 and a piston 110, as shown in Figs. 1 and 2, the fixing member ( 210), the inlet (1a) and an outlet (1b) are formed in the filter assembly 1 built-in, and the ever respective inlet (1a) and an outlet (1b) are each checked only opening is possible reverse to each other by a valve structure the will be.

즉, 주사기는 약물이 충진되도록 내공간을 갖는 실린더(100)에 피스톤(110)이 내장된 상태에서 피스톤(110)을 후방으로 당기면 실린더(100)가 진공상태가 되면서 흡입력을 발생시키고 이에 따라 흡입구(1a)를 개방하여 앰플에 담겨져 있는 약액을 흡입하여 실린더 내부로 빨아들이게 되는 것이고, 그 상태에서 앰플을 제거한 후 반대로 피스톤(110)을 밀어서 실린더(100) 내부에 압력을 발생시키면 충진되어 있는 약액을 배출구(1b)를 통하여 외부로 배출시켜 환자에게 주사가 가능토록 되는 것이다. That is, the syringe is the drug is pulling the piston 110 in the piston 110, the internal state in the cylinder 100 with the space to be filled by rearward to generate a suction force of the cylinder 100. As the vacuum Accordingly inlet (1a) and opens the suction of the chemical liquid that contained in the ampoule will be Soak into the cylinder, the chemical solution that is filled raises the pressure therein after removing the ampoule from its state opposed to pushing the piston 110, the cylinder 100, that will ever by the through the outlet (1b) can be discharged out of the injection to the patient.

이를 위하여 상기 흡입구(1a)와 배출구(1b)를 형성함에 있어, 필터구조체(1)에 원통형의 관로(10a,10b)를 형성하고 각각의 관로(10a,10b)에는 타방향 단부에 가림막(11a,11b)을 형성하며, 그 가림막(11a,11b)은 반구형의 형태로 외측으로 돌출되게 형성하면서 중앙부에 절개선(12a,12b)을 형성하면 가림막(11a,11b)이 일방향으로만 개방되어지게 되는 것이다. Here as To this end forming the inlet (1a) and an outlet (1b), the filter structure (1) form a conduit (10a, 10b) of the cylinder and each of the conduits (10a, 10b) have their screening at the other ends to (11a , 11b) in the formation, and that their screening (11a, 11b) will be the only opening to when and formed to protrude outward in a semi-spherical shape form the incision (12a, 12b) at the center their screening (11a, 11b) is a one-way It will be.

즉, 도 2에 도시된 바와 같이 약액의 흡입시 피스톤(110)을 당겨서 주사기 실린더(100) 내측으로 흡입력이 발생하도록 하면 흡입구(1a)에 위치되는 가림막(11a)의 절개선(12a)이 실린더 내측방향으로 벌어지게 되는 것이고, 피스톤(110)을 계속적으로 잡아당기게 되면 앰플에 담겨져 있는 약액을 주사기 실린더(100)에 충진할 수 있게 되는 것이다. That is, an incision (12a) for pulling the suction when the piston 110 of chemical solution syringe cylinder 100. When so that the suction force generated inside their screening (11a) positioned in the inlet (1a) in the cylinder, as shown in which will be going to the inside direction, and when pulled out continuously by the piston 110 will be immersed in the drug solution to the ampoules can be filled into the syringe cylinder (100).

반대로, 환자에게 주사기에 담겨진 약액을 투여하고자 할 경우에는 피스톤(110)을 밀어서 도 3에 도시된 바와 같이 주사바늘 방향으로 배출력이 발생하도록 하면 배출구(1b)에 위치되는 가림막(11b)의 절개선(12b)이 주사바늘 방향으로 벌어지게 되는 것이고, 피스톤(110)을 계속적으로 밀게 되면 실린더 내부에 충진되어 있는 약액을 환자에게 투여할 수 있게 되는 것이다. In contrast, when a patient to be administered the drug solution contained in the syringe is when to the ship output generated by scanning the hand direction as shown in Figure 3 by pushing the piston (110) sections of their screening (11b) which is located at the outlet (1b) improvement (12b) that will be going in the direction of the injection needle, it is possible to continue to push when the piston (110) administering the drug solution that is filled into the inner cylinder to the patient.

이때, 상기 흡입구(1a)와 배출구(1b)가 일방향으로만 개방되어지는 원리는 각각의 가림막(11a,11b)의 형태가 반원형의 역방향으로 가림막이 형성되어 있으므로 흡입시 또는 배출시 각각의 흡입구(1a)와 배출구(1b)에는 항력의 차이가 발생하게 되고, 이에 따라 피스톤을 당겨서 실런더의 내부방향으로 압력이 발생할 때에는 흡입구(1a)의 가림막(12a)에 형성된 절개선(12a)이 벌어지면서 흡입구(1a)가 개방됨과 동시에 배출구(1b)가 닫힌 상태를 유지하게 되는 것이고, 반대로 피스톤을 밀어서 실린더(100)에서 주사바늘(200) 방향으로 압력이 발생할 경우에는 배출구(1b)의 가림막(12b)에 형성된 절개선(12b)이 벌어지면서 배출구(1b)가 개방됨과 동시에 흡입구(1a)가 닫힌 상태를 유지하게 되는 것이다. At this time, each of the inlet the inlet (1a) and an outlet (1b) is a one-way principle that only the open, because the shape of each of their screening (11a, 11b) their screening is formed in a direction opposite to the semi-circular when inhaled or discharged ( 1a) and an outlet (1b) there is the difference in drag occurs, so that the incision (12a formed in their screening (12a) of the inlet (1a) when the pressure in the inner direction of the yarn London's caused by pulling the piston), the as happened inlet (1a) is opened as soon at the same time would be to keep a state in which the outlet (1b) is closed, on the contrary, if pushing the pressure occurs in the cylinder 100 with the injection needle 200, the direction the piston is their screening of the discharge opening (1b) (12b ) incision (12b) is formed on going as soon as the outlet opening (1b) will be at the same time to maintain a state in which the inlet (1a) is closed.

또한, 상기 배출구(1b)의 관로(10b)상에는 필터(13)를 내장하여 약액이 배출될 경우 미세한 유리조각이나 고무조각과 같은 이물질이 통과되지 못하고 실린더 내부에 잔류토록 되는 것이고, 이에 따라 환자에게 투여되는 약액은 이물질이 함유되지 않은 상태로 안전하게 투여할 수 있게 되는 것이다. In addition, it will be if the liquid medicament is discharged in a built-in filter 13. On the conduit (10b) of said discharge opening (1b) not foreign material, such as fine glass or rubber pieces are passed through ever remaining in the cylinder, and thus to the patient, depending chemical to be administered will be able to safely administered to a state that is not comprised of debris.

한편, 상기 필터구조체(1)는 도 4 및 도 4a에 도시된 바와 같이 필터판(20)의 양면에 관통홀(21a)과 절개선(21b)이 형성된 실리콘 러버(21)를 부착하여 절개선(21b)이 필터(20)의 외측으로만 벌어짐되도록 함으로써 필터구조체(1)의 흡입구(1a)와 배출구(1b)가 체크밸브 구조를 갖도록 하고, 상기 실리콘 러버(21)는 양측이 서로 대칭되게 부착함으로써 절개선(21b)의 벌어짐에 의하여 양측이 서로 다른 역방향으로 개방되어 피스톤(110)을 당기거나 밀때 발생하는 흡입력과 배출력에 대응되게 흡입구(1a)와 배출구(1b)가 각각 개방되어지도록 할 수 있는 것이다. On the other hand, the filter assembly 1 is improved v attached to the through-hole (21a) and the incision silicone rubber (21), (21b) are formed on both sides of the filter plate 20 as shown in Figure 4 and Figure 4a (21b) inlet port (1a) and an outlet (1b) is to have a check valve structure, the silicon rubber 21 of the filter structure (1) to ensure that only flaring outwardly of the filter 20 is presented both sides are symmetrical to each other adhesion by ensuring the two sides are open, each with suction and times the output corresponding to be the inlet (1a) and an outlet (1b) on a pull or generated milttae open the piston 110 in the other reverse direction by the flaring of the incision (21b) it can be.

즉, 도 5에 도시된 바와 같이 약액의 흡입시 피스톤(110)을 당겨서 주사기 실린더(100) 내측으로 흡입력이 발생하도록 하면 두 개의 실리콘 러버(21) 중 흡입구(1a)에 절개선(21b)이 위치된 실리콘 러버(21)의 절개선(21b)이 실린더 내측방향으로 벌어지게 되는 것이고, 피스톤(110)을 계속적으로 잡아당기게 되면 앰플에 담겨져 있는 약액을 주사기 실린더(100)에 충진할 수 있게 되는 것이다. That is, by pulling the suction when the piston 110 of chemical solution syringe cylinder (100) when the suction force to be generated in the inner incision (21b) to the inlet (1a) of the two silicone rubber 21, as shown in Figure 5 is incision of the position silicone rubber (21), (21b), a will that would be going to the cylinder inside direction, when stretched continuously to hold the piston 110, which is a drug solution that contained in the ampoule can be filled into the syringe cylinder (100) will be.

반대로, 환자에게 주사기에 담겨진 약액을 투여하고자 할 경우에는 피스톤(110)을 밀어서 도 6에 도시된 바와 같이 주사바늘 방향으로 배출력이 발생하도록 하면 배출구(1b)에 위치되는 실리콘 러버(21)의 절개선(21b)이 주사바늘 방향으로 벌어지게 되는 것이고, 피스톤(110)을 계속적으로 밀게 되면 실린더 내부에 충진되어 있는 약액을 환자에게 투여할 수 있게 되는 것이다. In contrast, when a patient to be administered the drug solution contained in the syringe is when to the ship output generated by scanning the hand direction as shown in Figure 6 by pushing the piston 110, the silicon rubber 21, which is located at the outlet (1b) which will be going to the incision (21b) the needle direction, it is possible to continue to push when the piston (110) administering the drug solution that is filled into the inner cylinder to the patient.

이때, 상기 흡입구(1a)와 배출구(1b)가 일방향으로만 개방되어지는 원리는 각각의 각각의 절개선(21b)이 필터판(20)에 의하여 막혀져 일방향으로만 벌어짐되고, 이에 따라 피스톤을 당겨서 실런더의 내부방향으로 압력이 발생할 때에는 흡입구(1a)측의 절개선(21b)이 벌어지면서 흡입구(1a)가 개방됨과 동시에 배출구(1b)가 닫힌 상태를 유지하게 되는 것이고, 반대로 피스톤을 밀어서 실린더(100)에서 주사바늘(200) 방향으로 압력이 발생할 경우에는 배출구(1b)측의 절개선(21b)이 벌어지면서 배출구(1b)가 개방됨과 동시에 흡입구(1a)가 닫힌 상태를 유지하게 되는 것이다. In this case, the principle being that the inlet (1a) and an outlet (1b) are open only in one direction has been turned respectively, of the respective incision (21b) is blocked by the filter plate (20) flaring only in one direction, the piston accordingly pulling when the pressure in the inner direction of the yarn London's experience will inlet (1a) side of the incision (21b) is going as the soon as the inlet (1a) open done at the same time maintaining a state in which the outlet (1b) is closed, on the contrary by pushing the piston If the pressure occurs in a cylinder 100 in the injection needle 200 direction as going the incision (21b) of the discharge opening (1b) side soon as the outlet (1b) open at the same time being kept a state in which the inlet (1a) closed will be.

또한, 상기 필터판(20)은 흡입구(1a)가 형성되는 위치에 슬롯홀(20a)을 형성하면 주사기의 실린더로 약액을 흡입할 경우 이물질이 필터에 걸림되지 않고 함께 유입되도록 하는 것으로, 약액을 흡입한 상태에서 필터판(20) 외측으로 이물질이 잔류하게 되는 것을 방지하고 전량 실린더 내부로 유입되도록 한 것이다. Further, when the filter plate 20 is formed a slot-hole (20a) at a position where the inlet (1a) formed by such flows with not jam in the foreign matter filter when aspirating the chemical liquid in the cylinder of the syringe, the drug solution protection from a suction status to the outer filter plate 20 in that the foreign material will remain and that the total amount introduced into the cylinder.

따라서 주사바늘의 교체없이 약액을 흡입한 주사바늘을 그대로 사용하는 경우에도 약액을 환자에게 주사할 때 흡입구(1a)의 외측에 이물질이 잔류하지 않으므로 약액과 함께 주사되는 것을 방지할 수 있고, 상기 실린더의 내부에서는 필터판(20)에 의하여 약액에 함유된 이물질이 배출되지 못하고 실린더 내부에 잔류하게 되면서 역시 환자에게 주입되는 약액에 이물질이 섞여 배출되는 것을 방지할 수 있게 되는 것이다. Therefore, it is possible to prevent to scan the drug solution, even if used as a needle aspirating the chemical liquid without replacement of the needle to the patient does not have residual foreign material on the outside of the inlet (1a) is scanned with the drug solution, the cylinder in the inside as it does not remain on the inside by a filter plate 20 discharge the foreign materials contained in the chemical liquid cylinder it is possible also to prevent the mixture of foreign matter in the drug solution to be injected to the patient discharged.
