The medicine delivery tip is needle tip (200) or a connection tip (310) of an aqueous solution set (300).

Description

더블 챔버형 주사제 용기 및 더블 챔버형 일회용 주사기{Medicine container with double chamber and disposable syringe including the container}Medicine container with double chamber and disposable syringe including the container}

본 발명은, 서로 다른 약제가 각각의 챔버에 격리 수용되어 있다가 외부로부터 기준치 이상의 압력이 가해진 때 양 챔버가 연통되어 약제가 혼합되도록 구성된 더블 챔버형 주사제 용기와, 이러한 더블 챔버형 주사제 용기를 포함하여 구성되는 일회용 주사기에 관한 것이다.The present invention includes a double-chambered injector container configured to allow the two chambers to communicate with each other when the different medicines are contained in each chamber in a separate chamber, and when the pressure from the outside is applied. It relates to a disposable syringe configured to.

여기서, 본 발명에 의해 최초로 제안되는 더블 챔버형 일회용 주사기는 기존에 없던 물품으로서, 약병 속의 약물을 주사기로 뽑아낸 다음, 종래 구성의 수액제 용기(백이나 병 형태)의 고무마개에 주사기 바늘을 꽂아 용기 안으로 약물을 주입할 필요가 전혀 없다는 사용상 편리성을 제공함과 아울러, 다른 종류의 약물이 각각 들어 있는 주사기들이 뒤섞여 있을 때 야기될 수 있는 예기치 않은 약화 사고도 미연에 방지하는 효과를 제공한다.Here, the double chamber-type disposable syringe first proposed by the present invention is an existing article, and the drug in the vial is drawn out by a syringe, and then a syringe needle is inserted into a rubber stopper of a fluid container (bag or bottle form) of a conventional configuration. In addition to providing convenience in that there is no need to inject the drug into the container, it also provides the effect of preventing unexpected weaknesses that may occur when the syringes containing different types of drugs are mixed together.

본 발명의 선행기술로서 예를 들면, 특허문헌 1에 개시된 이중 챔버 수액 용기가 알려져 있다.As a prior art of this invention, the double chamber fluid container disclosed by patent document 1 is known, for example.

When the mixed medicine to be mixed and administered to the patient is prepared, the injection needle is inserted into the rubber stopper of the drug outlet provided in the liquid chamber to allow the mixed drug to flow out.

그러나 이러한 구성에 따르면 다음과 같은 문제가 있다.However, this configuration has the following problems.

(1) 고무마개에 주사 바늘을 찔러 넣을 때, 고무가루나 고무파편이 떨어져 나와 혼합 약제에 섞일 수 있다.(1) When the needle is inserted into the rubber stopper, rubber powder or debris may come off and mix with the mixed agent.

(2) 고무마개에 주사 바늘이나 수액 세트의 스파이크를 찔러 넣을 때, 자칫하면 주사 바늘이 구부러지거나 스파이크가 부러져 버릴 수 있다.(2) When inserting a spike of an injection needle or an infusion set into a rubber stopper, the needle may bend or the spike may break.

본 발명에 따른 더블 챔버형 주사제 용기와 이 용기를 포함하는 일회용 주사기는, 다음과 같은 이점을 갖는다.The double chamber-type injectable container according to the present invention and the disposable syringe including the container have the following advantages.

(1) 약제 배출구측에 나사체결방식으로 결합되어 있는 뚜껑을 분리시킨 후, 그 자리에 약물 전달 팁을 나사체결방식으로 결합시켜 사용하므로, 환자에게 혼합 약제를 투여하기 위해, 종래처럼, 고무마개에 주사 바늘을 찔러 넣을 필요가 없다.(1) Since the lid is coupled to the drug outlet side by screwing, the drug delivery tip is screwed into place and used, so that a rubber stopper can be used to administer the mixed drug to the patient. There is no need to poke a needle in.

따라서 고무가루 등이 떨어져 나와 혼합 약제에 섞이는 일이 없다.Therefore, rubber powder does not come off and mix with the mixed medicine.

(2) 고무마개에 주사 바늘이나 스파이크를 찔러 넣는 일이 없으므로 주사 바늘이 구부러지거나 스파이크가 부러지는 일도 생기지 않는다.(2) No needle or spike is inserted into the rubber stopper, so that the needle does not bend or break the spike.

(3) 또, 약제 배출구의 외면과 수용단의 내면 사이에 형성되는 링 형상의 홈 안으로 약물 전달 팁의 결합부위를 끼워 넣어 체결하므로, 빈틈없는 결합이 이루어져, 약물의 누출이 생기지 않는다.(3) In addition, since the coupling portion of the drug delivery tip is inserted into the ring-shaped groove formed between the outer surface of the drug outlet and the inner surface of the receiving end, a tight coupling is made and no drug leakage occurs.

이하, 도 1, 도 2, 도 3(a)을 참조하여, 본 발명에 따른 더블 챔버형 주사제 용기의 구성과 작용효과에 대해 설명한다.Hereinafter, with reference to FIG. 1, FIG. 2, FIG. 3 (a), the structure and effect of the double chamber type injection container which concerns on this invention are demonstrated.

본 발명에 따른 더블 챔버형 주사제 용기는, 이들 도면에 도시된 바와 같이, 용기(100)와 뚜껑(140)으로 구성되어 있다.The double chamber injection container according to the present invention, as shown in these figures, is composed of a container 100 and a lid 140.

용기(100)는 대략적으로 그 형상이 튜브 형태로서, 상하방향의 대략 중간 지점에 형성되어 있는 접합부(120)에 의해, 상부측의 제1 챔버(110)와 하부측의 제2 챔버(130)로 구획되어 있다. 여기서, 상부측의 제1 챔버(110)에는 예를 들면, 액체 상태의 제1 약제(M1)가 수용되고, 하부측의 제2 챔버(130)에는 분말 상태의 제2 약제(M2)가 수용되어 있다.The container 100 has a tube shape that is approximately in the form of a tube, and the first chamber 110 on the upper side and the second chamber 130 on the lower side are formed by the joining portion 120 formed at an approximately intermediate point in the vertical direction. It is divided into Here, for example, the first drug M1 in a liquid state is accommodated in the first chamber 110 on the upper side, and the second drug M2 in a powder state is accommodated in the second chamber 130 on the lower side. It is.

그리고 접합부와 마주보는 측인 제1 챔버(110)의 상단측에는, 제1 챔버의 내부공간과 연통된 유로(151)를 갖는 약제 배출구(150)가 형성되어 있다. 아울러, 이 약제 배출구(150)의 외주면으로부터 일정 간격을 두고 약제 배출구를 둘러싸는 링 형상의 수용단(160)이 약제 배출구와 일체로 형성되어 있다. 이 수용단(160)의 내주면(內周面)에는 암나사(161)가 형성되어 있다.And the upper end of the first chamber 110 that is the side facing the junction, the drug outlet 150 having a flow path 151 in communication with the inner space of the first chamber is formed. In addition, a ring-shaped receiving end 160 surrounding the drug outlet at a predetermined interval from the outer peripheral surface of the drug outlet 150 is formed integrally with the drug outlet. A female screw 161 is formed on the inner circumferential surface of the receiving end 160.

다음으로, 뚜껑(140)은, 단면(斷面) T 형상의 고무마개(142)와, 이 고무마개가 내부로 끼워지는 큰지름부와 약제 배출구가 안으로 끼워지는 작은지름부로 이루어지고 또 작은지름부의 외주면에는 수나사(143)가 형성되고 큰지름부와 작은지름부는 내부가 연통되어 있는 플라스틱 재질의 몸체(141)로 구성되어 있다.Next, the lid 140 is formed of a rubber stopper 142 having a cross-sectional T shape, a large diameter portion into which the rubber stopper is fitted, and a small diameter portion into which the drug discharge port is inserted. A male screw 143 is formed on the outer circumferential surface, and a large diameter portion and a small diameter portion are formed of a plastic body 141 in which the inside is in communication.

따라서 약제 배출구(150)가 뚜껑(140)으로 틀어막힌 상태에서 제1 챔버나 제2 챔버 중 어느 한쪽을 기준치 이상의 힘으로 누르게 되면, 양 챔버를 구획하고 있던 접합부(120)가 뜯어지면서, 도 3(a)에 도시된 것처럼, 양 챔버가 연통된다.Therefore, when the drug outlet 150 is pressed by a force greater than or equal to either the first chamber or the second chamber in a state in which the lid 140 is clogged with the lid 140, the joining portion 120 partitioning both chambers is torn off, Figure 3 As shown in (a), both chambers are in communication.

이에 의해, 양 챔버에 각각 격리 수용된 제1 약제(M1)와 제2 약제(M2)가 섞여, 환자에게 투여할 혼합 약제(M3)가 조제된다.Thereby, the 1st chemical | medical agent M1 and the 2nd chemical | medical agent M2 seperately accommodated in both chambers are mixed, and the mixed chemical | medical agent M3 to administer to a patient is prepared.

그 후 뚜껑을 돌려 빼내고, 대신 그 자리에, 도 3(b)에 도시된 니들 팁(200)의 나사부(210)나 도 4에 도시된 수액 세트(300)의 연결 팁(310)의 나사부(320)를 돌려 끼움으로써, 더블 챔버형 일회용 주사기가 얻어진다.The lid is then pulled out, and in place, instead of the threaded portion 210 of the needle tip 200 shown in FIG. 3 (b) or the threaded portion of the connection tip 310 of the fluid set 300 shown in FIG. By screwing 320), a double chambered disposable syringe is obtained.

여기서 니들 팁의 나사부(210)나 수액 세트의 연결 팁의 나사부(320)나 뚜껑의 작은지름부에 형성된 수나사(143)는 링 형상의 수용단(160)과 약제 배출구(150) 사이의 환형(環形) 홈에 나사체결방식으로 결합되므로, 빈틈없는 결합되어, 약물의 누출이 전혀 생기지 않는다.Here, the threaded portion 210 of the needle tip or the threaded portion 143 formed on the threaded portion 320 of the connection tip of the infusion set or the small diameter portion of the lid has an annular shape between the ring-shaped receiving end 160 and the drug outlet 150. 결합 形 Because it is screwed into the groove, it is tightly coupled, no drug leakage occurs.

본 발명은, 상술한 실시형태로 한정되는 것은 아니고, 다양한 변형이 가능하다. 예를 들면, 상기 실시형태에서는, 2개의 챔버만 갖는 것으로 설명했지만, 챔버 수가 3개 이상이어도 좋다. 또, 제2 챔버에 격리 수용되는 제2 약제는 분말 상태가 아닌 액상이어도 좋다. 또, 도면에는, 제1 챔버와 약제 배출구(150)가 일체로 성형된 형태로 도시되었지만, 약제 배출구가 별개의 부품으로 제조된 후 제1 챔버의 상단측에 가열부착되어 일체화되는 구성이어도 좋다.This invention is not limited to embodiment mentioned above, A various deformation | transformation is possible. For example, in the said embodiment, it demonstrated as having only two chambers, but three or more chambers may be sufficient. In addition, the second chemical agent contained in the second chamber may be a liquid rather than a powdered state. In addition, in the figure, although the first chamber and the drug outlet 150 are shown integrally molded, the drug outlet may be made of a separate component and then heated and attached to the upper end of the first chamber to be integrated.
