Description

허브밀착식 주사기용 필터캡{HUB CONTACT TYPE FILTER CAP FOR SYRINGE}HUB CONTACT TYPE FILTER CAP FOR SYRINGE}

본 발명은 주사기용 필터캡에 관한 것으로서, 보다 상세하게는, 필터와 하우징을 구비하여 주사바늘을 보호함과 아울러 주사액 유리 앰플을 부러뜨릴때 발생하여 침전된 미세한 유리조각 등의 이물질이 주사기에 들어가는 것을 막아 인체내부에 이물질이 주사되는 것을 방지하고 주사바늘을 외부로 노출시키지 않고도 주사액을 충전할 수 있도록 하며 주사바늘 교체시 바늘에 찔려 발생할 수 있는 안전사고를 방지하는 주사기용 필터캡에 관한 것이다.The present invention relates to a filter cap for a syringe, and more particularly, to provide a filter and a housing to protect a needle, and to allow foreign substances such as fine glass chips, which are generated when the injection liquid glass ampoule is broken, get into the syringe. The present invention relates to a filter cap for a syringe which prevents foreign substances from being injected into the human body to prevent injection, filling the injection liquid without exposing the needle to the outside, and preventing a safety accident that may be caused by a needle stick when the needle is replaced.

주사액 유리앰플은 목을 부러뜨려서 사용하기 때문에 미세한 유리조각이 주사액에 섞이게 된다. 미세한 유리조각은 주사액과 같이 주사기에 흡입 충전되고, 결국 인체에 같이 주사되는 문제가 있다.Syringes Glass ampoules are used by breaking the neck, so fine glass pieces are mixed with the injection. Fine pieces of glass are inhaled and filled into the syringe like injection liquid, and thus are injected into the human body.

의료계에서는 유리앰플을 깨뜨려 개봉할 때 발생한 미세한 유리조각이 주사바늘을 통해 인체로 주사되어 혈전을 일으켜 심근경색, 뇌졸증과 같은 치명적인 질환을 유발할 수 있다는 가능성을 제기하였다.The medical community has raised the possibility that minute glass fragments generated when the glass ampoule is broken and opened can be injected into the human body through a needle, causing blood clots to cause fatal diseases such as myocardial infarction and stroke.

식약청 연구용역 보고서에서도 유리앰플의 주사액에 섞인 유리파편들이 정맥주사를 통해 약물과 함께 체내에 주입되면 폐, 간, 비장 등 장기에서 염증반응과 육아종 형성 등 병리학적 변화를 일으킬 가능성도 제기한 바있고, 특히 2004년 식약청 연구용역보고서에는 사람의 폐 모세혈관 지름이 10㎛이므로 이보다 큰 유리파편 같은 불용성 이물질이 인체에 축적되면 폐색전증과 같은 심각한 질환을 유발할 수 있음을 지적하였다.The KFDA's research report also raised the possibility of causing pathological changes such as inflammation and granuloma formation in the lungs, liver, spleen and other organs when the glass fragments mixed with injections of glass ampoule are injected into the body with drugs through intravenous injection In particular, the KFDA's research report in 2004 pointed out that human lung capillary diameter is 10 μm, which means that accumulation of insoluble foreign substances such as glass fragments in the body can cause serious diseases such as pulmonary embolism.

이러한 문제를 해결하기 위해 필터를 장착한 주사기 등의 종래기술이 제안된 바 있다. 그런데, 상기 종래 기술은 주사바늘밀착로가 주사바늘과 밀착하여 음압을 형성한다. 따라서 주사바늘밀착로는 주사바늘의 외경에 근접하는 내경으로 형성된다. 여기서 몇가지 문제점이 발생한다. 첫째 사출생산을 위해 필요한 금형의 갯수가 많아 비용이 크다. 둘째 금형의 수가 많아 사출형성이 과정이 복잡해져서 불량율이 크다. 셋째 주사바늘밀착로의 내경이 좁아 주사바늘과 필터캡을 결합할 때 주사바늘의 끝부분이 주사바늘밀착로를 통과하는 과정에서 손상되어 뭉툭해져 주사할 때 환자에게 통증을 주게된다. 넷째 주사바늘밀착로는 주사바늘의 크기와 짝을 이루기 때문에 다양한 크기의 주사바늘에 대응하는 필터캡을 각각 생산하고 사용해야한다.In order to solve this problem, a conventional technology such as a syringe equipped with a filter has been proposed. By the way, the prior art is in close contact with the needle to form a negative pressure in close contact with the needle. Therefore, the needle contact path is formed with an inner diameter close to the outer diameter of the needle. Some problems arise here. First, the cost is high because the number of molds required for injection production is large. Second, the number of molds is high, so the injection molding process is complicated, so the defect rate is high. Third, the inner diameter of the needle contacting furnace is narrow, and when the needle and the filter cap are combined, the tip of the needle is damaged in the process of passing through the needle contacting furnace, causing a pain in the patient when injecting. Fourth, because the needle close contact is paired with the size of the needle, it is necessary to produce and use filter caps corresponding to the needles of various sizes.

이에 본 발명은 상기에 서술한 바와 같은 종래 주사기용 필터캡의 문제점을 해결하기 위한 것으로, 그 목적은 종래보다 생산에 필요한 금형의 갯수가 줄고 구조가 단순하고, 사출생산에서 불량율이 작고, 주사바늘과 결합 과정에서 주사바늘에 손상이 생기지 않으며, 다양한 외경 크기의 주사바늘에 대응하는 허브밀착식 주사기용 필터캡을 제공함에 있다.Accordingly, the present invention is to solve the problem of the conventional filter cap for the syringe as described above, the object is to reduce the number of molds required for production and simple structure than the conventional, the defect rate in the injection production is small, the needle In the process of combining with the needle does not cause damage, it provides a filter cap for the hub-contact syringe corresponding to the needle of various outer diameters.

상기 목적을 달성하기 위한 본 발명에 따른 허브밀착식 주사기용 필터캡은 하우징의 내부에 용융접착으로 장착된 필터, 하우징 내의 음압형성을 위해 주사바늘고정허브와 밀착하도록 주사바늘고정허브밀착돌출부, 주사바늘이 부드럽게 삽입되도록 하우징 내에 형성된 경사로를 특징으로 한다.Filter cap for hub-adhesive syringe according to the present invention for achieving the above object is a filter attached to the inside of the housing by melt adhesion, needle fixed hub adhesion protrusion, needle to close contact with the needle fixing hub to form a negative pressure in the housing It is characterized by a ramp formed in the housing so as to be inserted smoothly.

본 발명의 허브밀착식 주사기용 필터캡은 주사바늘고정허브밀착돌출부가 주사바늘밀착로를 대신하여 내경 폭이 가장 좁은 곳이 주사바늘삽입로가 되어 종래의 기술보다 금형의 갯수가 줄고 구조가 단순하며, 사출생산에서 불량율이 작고, 주사바늘과 결합 과정에서 주사바늘에 손상이 생기지 않으며, 다양한 외경 크기의 주사바늘에 대응할 수 있는 장점을 가진다.The filter cap for the hub-adherent syringe of the present invention has a narrow inner diameter in place of the needle fixing hub-adhesive protrusion instead of the needle-adhesive path, so that the number of molds is reduced and the structure is simpler than the prior art. In addition, the defect rate is small in the injection production, the needle does not damage the needle during the bonding process, and has the advantage that can cope with the needle of various outer diameters.

본 발명에서 사용되는 용어는 가능한 현재 널리 사용되는 일반적인 용어를 선택하였으나, 특정한 경우는 출원인이 임의로 선정한 용어도 있는데 이 경우에는 단순한 용어의 명칭이 아닌 발명을 실시하기 위한 구체적인 내용에 기재되거나 사용된 의미를 고려하여 그 의미가 파악되어야 할 것이다. The term used in the present invention is a general term that is widely used at present. However, in some cases, there is a term selected arbitrarily by the applicant. In this case, the term used in the present invention It is necessary to understand the meaning.

이하, 첨부한 도면에 도시된 바람직한 실시 예들을 참조하여 본 발명의 기술적 구성을 상세하게 설명한다. Hereinafter, the technical structure of the present invention will be described in detail with reference to preferred embodiments shown in the accompanying drawings.

먼저, 도 2는 본 발명에 따른 허브밀착식 주사기용 필터캡(7)을 도시한 사시도 이며, 도 3은 본 발명에 따른 허브밀착식 주사기용 필터캡(7)을 도시한 단면도이다. First, FIG. 2 is a perspective view showing a filter cap 7 for a hub-contact syringe according to the present invention, and FIG. 3 is a cross-sectional view showing a filter cap 7 for a hub-contact syringe according to the present invention.

도 2와 도 3을 참조하면 상기 필터캡(7)은 필터(701), 앰플삽입관(702), 탈거지지대(703), 주사액유입로(704), 주사바늘삽입로(705), 경사로(706), 주사바늘고정허브삽입로(708)을 포함한다. 2 and 3, the filter cap 7 includes a filter 701, an ampule insertion pipe 702, a removal support 703, an injection liquid inlet 704, a needle insertion path 705, and an inclined path ( 706), the needle fixing hub insertion path (708).

이때, 상기 필터(701)는 주사액유입로(704)와 주사바늘삽입로(705)의 연통부분에 용융접착으로 고정되며 모세혈관의 지름이 10㎛이므로 그보다 작은 유리조각의 여과에 임계적 의의가 있으므로 필터(701)는 10㎛ 이하의 투과성을 가지는 것이 바람직하며, 본 발명의 바람직한 실시 예에 있어서는 5㎛ 이하의 투과성을 갖는 필터를 사용하였다. At this time, the filter 701 is fixed to the fusion bonding between the injection liquid inlet 704 and the needle insertion path 705 and the capillary diameter of 10㎛ because of the critical significance for the filtration of glass fragments smaller than that Therefore, the filter 701 preferably has a transmittance of 10 μm or less, and in the preferred embodiment of the present invention, a filter having a transmittance of 5 μm or less is used.

아울러 필터(701)는 화학적으로 안정하여 주사액과 반응하지 않고 용융접착이 가능한 다양한 재료를 통해 구비될 수 있다. In addition, the filter 701 may be provided through various materials that are chemically stable and can be melt-bonded without reacting with the injection liquid.

한편, 앰플삽입관(702)은 앰플(8)에 삽입되는 부분으로 개봉된 앰플(8)의 개봉부의 일반적인 내경이 4mm~10mm이므로 그 이하의 외경을 가져야하며 접촉 오염을 막기 위해 3mm이하의 외경이 바람직하다. On the other hand, the ampoule insertion tube 702 is a part to be inserted into the ampoule 8, so the general inner diameter of the opening of the ampoule 8 is 4 mm to 10 mm, so it should have an outer diameter of less than that and an outer diameter of 3 mm or less to prevent contact contamination. This is preferred.

한편, 주사액유입로(704)는 앰플(8)의 주사액이 유입되는 부분으로 도 6에서와 같이 주사액 충전시 일단부가 앰플의 벽에 밀착되어야하므로 경사진 것이 편리하다. On the other hand, the injection solution inlet 704 is a portion in which the injection solution of the ampoule 8 is introduced, as shown in Figure 6 when the injection liquid filling is inclined because it is in close contact with the wall of the ampoule.

이때, 필터(701)가 용융접착되려면 돌출부가 있어야하는데, 주사액유입로(704)는 주사바늘삽입로(705)보다 직경이 커야 돌출부가 발생하므로, 주사액유입로(704)는 주사바늘삽입로보다 직경이 커야하며, 본 발명의 바람직한 실시 예에 있어서는 0.8mm정도의 차이가 생기도록하였다. At this time, the filter 701 must have a protrusion to be melt-bonded, but the injection liquid inlet 704 has a diameter larger than the needle insertion path 705 so that the protrusion occurs, so that the injection liquid inlet 704 is larger than the needle insertion path. The diameter should be large, and in the preferred embodiment of the present invention, a difference of about 0.8 mm is generated.

한편, 주사바늘삽입로(705)는 주사바늘(6)이 삽입되는 부분으로 주사액유입로(704)와 연통되게 연결되어 하우징에 관통되어있으며, 삽입될 주사바늘(6)의 외경보다 직경이 커야하며, 본 발명의 바람직한 실시 예에 있어서는 1.2mm의 직경으로 형성하여 주사바늘 직경이 1.067mm 인 19게이지보다 작은 바늘을 사용할 수 있도록 하였다.On the other hand, the injection needle insertion path 705 is a part into which the injection needle 6 is inserted and connected to the injection liquid inlet path 704 so as to penetrate the housing and have a diameter larger than the outer diameter of the injection needle 6 to be inserted. In the preferred embodiment of the present invention, a needle having a diameter of 1.2 mm was used to allow a needle smaller than 19 gauge having a needle diameter of 1.067 mm.

한편, 경사로(706)는 주사바늘이(6) 삽입될 때 걸림없이 주사바늘삽입로(705)로 이동되도록 하는 가이드부분으로 주사바늘삽입로(705)와 연통되게 연결되어 하우징에 관통되도록 하였다. 이는 자동화제조과정에서 주사바늘(6)이 하우징 내부에서 걸려 자동화설비 작동이 멈추는 문제를 해결하여 대량생산을 위한 자동화를 용이하도록 한다.On the other hand, the inclined path 706 is a guide portion to be moved to the needle insertion path 705 without jamming when the needle (6) is inserted in communication with the needle insertion path 705 is to penetrate the housing. This solves the problem that the needle 6 is caught inside the housing during the automated manufacturing process and stops the operation of the automation facility, thereby facilitating automation for mass production.

한편, 주사바늘고정허브삽입로(708)는 주사바늘고정허브(5)가 삽입되는 부분으로 경사로(706)와 연통되게 연결되어 하우징에 관통되어있으며, 주사바늘고정허브(5)가 삽입되도록 주사바늘고정허브(5)와 짝을 이루도록 관통된다.Meanwhile, the needle fixing hub insertion path 708 is a portion into which the needle fixing hub 5 is inserted, is connected to the inclined path 706 to penetrate the housing, and the needle fixing hub 5 is inserted thereinto. It penetrates to mate with the needle fixing hub (5).

이때, 주사바늘고정허브삽입로(708)에는 주사바늘고정허브밀착돌출부(709)가 형성되어 있어 주사바늘고정허브(5)와 밀착하여 하우징 내부에 음압을 형성시킨다.At this time, the needle fixing hub insertion path 708 is formed in the needle fixed hub close contact 709 is in close contact with the needle fixing hub 5 to form a negative pressure inside the housing.

이때, 주사바늘고정허브밀착돌출부(709)는 한 개 이상의 환(Ring)형(미도시)으로 형성될 수도 있고, 한 개 이상의 나선형 형태로 형성될 수도 있으며, 도4, 도5에 도시한 것과 같이 주사바늘고정허브밀착돌출부(709)와 짝을 이루는 주사바늘조립체와 함께 사용되는 경우 음압이 더 잘 형성되지만, 일반적인 주사바늘조립체와도 사용이 가능하다. 본 발명의 바람직한 일실시 예에서는 플라스틱 재질로 하우징을 형성하였는데, 온도에 따라 이완과 수축이 발생하는 플라스틱의 특성 때문에 온도에 따라 하우징이 주사바늘고정허브(5)에 꽉 끼거나 느슨해질 수 있는 문제가 있으며 나선형 형태의 경우 암수가 돌려서 체결되므로 온도에 따른 변화에도 체결력이 일관된 장점이 있다. 그에 반해 환형의 경우 나선형처럼 온도 변화에 대응하는 대신 탈부착이 손쉽고 빠른 장점을 가진다.In this case, the needle fixing hub contact protrusion 709 may be formed in one or more rings (not shown), or may be formed in one or more spiral forms, as shown in Figures 4 and 5 Likewise, when used with the needle assembly coupled to the needle fixing hub contact protrusion 709, the sound pressure is better formed, but can also be used with the general needle assembly. In a preferred embodiment of the present invention, the housing is formed of a plastic material, but the housing may become tight or loose in the needle fixing hub 5 depending on the temperature due to the characteristics of the plastic that relaxation and shrinkage occur depending on the temperature. In the case of spiral shape, the male and female are fastened by turning, so there is a consistent advantage in the fastening force even with changes in temperature. On the contrary, in the case of the annular shape, detachment is easy and quick instead of responding to temperature change like a spiral.

한편, 탈거지지대(703)는 상기 주사바늘고정허브삽입로(708) 부분의 하우징 외측에 형성되며, 상기 탈거지지대(703)는 손가락으로 미끄러짐 없이 잡을 수 있도록 다수의 돌출부로 이루어져 있어, 필터캡(7)을 주사바늘조립체와 밀어넣어 결합하거나 돌려서 결합할 때 손가락이 미끄러지지 않게 해준다.On the other hand, the removal support 703 is formed on the outer side of the housing of the needle fixing hub insertion path 708, the removal support 703 is composed of a plurality of protrusions so as to hold the finger without slipping, filter cap ( 7) slide the needle assembly with the needle assembly to prevent the fingers from slipping when engaged.

결과적으로 본 발명의 일실시 예에 따른 필터캡(7)은 상술한 구성들을 통해 사용이 편리하며 오염가능성과 바늘사고 가능성을 줄여준다. As a result, the filter cap 7 according to an embodiment of the present invention is convenient to use through the above-described configuration and reduces the possibility of contamination and needle accident.

또한, 일체형 하우징과 용융접착된 필터라는 단순한 구성을 통해 제조단가가 절감된다. In addition, the manufacturing cost is reduced through the simple configuration of the integral housing and the filter fusion bonded.

아울러, 적은 재료로 제조가 가능하여 환경보호의 측면에서도 우수한 효과가 있다. In addition, it is possible to manufacture with a small material has an excellent effect in terms of environmental protection.
