Description

혈류감염 방지용 항균 안전 캡{Antibacterial safety cap for preventing bloodstream infection}Antibacterial safety cap for preventing bloodstream infection}

본 발명은 카테터의 안전 캡에 관한 것으로서, 더욱 상세하게는 혈류감염 방지용 항균 안전 캡에 관한 것이다. The present invention relates to a safety cap for a catheter, and more particularly, to an antibacterial safety cap for preventing bloodstream infection.

일반적으로, 카테터(Catheter)는 환자의 혈관을 통해 환자의 치료 약물을 주입하기 위해 널리 사용되는 의료기구 중 하나이다. 이러한 카테터는 체내의 통증 부위로 약물을 주입하기 위해 사용되는 경우, 카테터의 선단을 체내의 통증 부위까지 투입하고 카테터의 후단에 주사기를 연결하여 주사기 내부에 채워진 약물을 카테터에 주입하는 방식으로 사용된다. In general, a catheter is one of the widely used medical devices for injecting a patient's therapeutic drug through a patient's blood vessel. When such a catheter is used to inject a drug into a pain site in the body, the front end of the catheter is inserted into the pain site in the body, and a syringe is connected to the rear end of the catheter to inject the drug filled inside the syringe into the catheter. .

여기서 카테터에는 이러한 주사기의 약물을 카테터의 후단으로 안정적으로 주입하기 위해 주사기와 카테터 사이에는 이들을 상호 연결하는 커넥터(안전 캡)가 사용되고 있다. Here, a connector (safety cap) is used between the syringe and the catheter to interconnect them in order to stably inject the drug from the syringe into the rear end of the catheter.

이러한 커넥터는 대략 원통 형상의 커넥터 본체와, 상기 커넥터 본체의 일방의 개구단에 배치된 탄성재료로 이루어지는 밸브체와, 상기 커넥터 본체의 밸브체 측 외주부에 커넥터 본체의 축방향으로 이동 가능하게 커넥터 본체에 대해 동축으로 배치된 대략 원통 형상의 접속부재를 포함한다.Such a connector includes a connector body having a substantially cylindrical shape, a valve body made of an elastic material disposed on one open end of the connector body, and a connector body that is movable in the axial direction of the connector body to the outer circumferential portion of the connector body on the valve body side. It includes a substantially cylindrical connecting member arranged coaxially with respect to.

한편 환자의 시술 또는 침습 과정 동안 그 치료 부위에서 카테터를 지속적으로 고정 및 유지시키기 위한 다양한 방법들이 공지되어 있다.Meanwhile, various methods are known for continuously fixing and maintaining a catheter at a treatment site during a patient's procedure or invasive procedure.

이러한 종래의 카테터는 주사연결 작업 등으로 인해 수시로 손이 접촉되는 대상이 되는데, 이와 같이 잦은 손 사용으로 인해 혈류감염이 높은 문제점이 제기되고 있다. 특히 카테터에 관련된 혈류감염은 중심정맥·말초정맥·동맥 등에 사용되는 카테터가 환자에게 삽입되거나, 커넥터를 교체할 때 감염이 되어 출혈과 부정맥, 심근 천공 등의 합병증을 유발하는 병원내 감염으로서, 주로 감염에 취약한 환자들이 모여 있는 중환자실에서 빈번히 발생되고 있는 실정이다. Such a conventional catheter is subject to frequent hand contact due to injection connection work, etc., and thus, a high problem of bloodstream infection has been raised due to frequent use of the hand. In particular, catheter-related bloodstream infections are infections in the hospital when catheters used in central veins, peripheral veins, and arteries are inserted into patients or connectors are replaced, causing complications such as bleeding, arrhythmia, and myocardial perforation. It is a situation that frequently occurs in intensive care units where patients who are vulnerable to infection are gathered.

한편 종래에는 도 1과 같이 안전 캡의 내부에 IPA(Isopropyl Alcohol)을 로딩한 거즈를 내부에 삽입한 안전 캡이 출시되어 종래의 혈류감염에 대응하고 있다. Meanwhile, as shown in FIG. 1, a safety cap in which a gauze loaded with IPA (Isopropyl Alcohol) is inserted into the safety cap has been released and is responding to conventional bloodstream infections.

그러나 이러한 종래의 안전 캡은 거즈가 이탈되는 사용상 문제가 제기되고 있고, 커넥터 말단의 일부만 거즈가 접촉되어 양호한 항균성을 확보하기 어려운 문제가 제기되었다.However, such a conventional safety cap has a problem in use that the gauze is separated, and only a part of the connector end is in contact with the gauze, so that it is difficult to secure good antibacterial properties.

도 1 내지 도 4를 참조하면, 본 발명은 카테터의 커넥터에 연결되는 안전 캡(10)을 제공한다. 본 발명의 안전 캡(10)은 몸체부(15)의 내부에 항균 밀폐부(12)와 항균 포스트부(11)가 수직방향으로 연속하여 연장형성된다. Referring to Figures 1 to 4, the present invention provides a safety cap 10 connected to the connector of the catheter. In the safety cap 10 of the present invention, an antibacterial sealing part 12 and an antibacterial post part 11 are formed to extend continuously in the vertical direction inside the body part 15.

구체적으로 몸체부(15)는 원통형으로 이루어지고, 그의 내주면에는 커넥터(20)의 외주면에 체결되는 체결 나사부(13)가 형성된다. Specifically, the body portion 15 is formed in a cylindrical shape, and a fastening screw portion 13 fastened to the outer circumferential surface of the connector 20 is formed on its inner circumferential surface.

또한 몸체부(15)의 외부면에는 안전 캡(10)의 체결시 미끌림 방지를 위해 다수의 슬립방지 리브(14)가 외부로 돌출된 형상으로 형성된다. In addition, a plurality of anti-slip ribs 14 are formed on the outer surface of the body 15 to protrude to the outside to prevent slipping when the safety cap 10 is fastened.

한편 몸체부(15)의 내부의 중앙에는 항균 밀폐부(12)가 일정높이만큼 수직방향으로 돌출형성된다. 또한 항균 밀폐부(12)의 상부에는 항균 포스트부(11)가 수직방향으로 돌출형성된다. On the other hand, the antibacterial sealing portion 12 protrudes in the vertical direction by a predetermined height at the center of the inside of the body portion 15. In addition, an antibacterial post portion 11 protrudes vertically from the top of the antibacterial sealing portion 12.

여기서 항균 밀폐부(12)는 항균 포스트부(11) 보다 넓은 지름을 가지며, 하방으로 갈수록 확대되는 지름을 갖는 원기둥의 형상으로 형성된다. 또한 항균 포스트부(11)는 항균 밀폐부(12)와 달리 동일한 지름을 갖는 원기둥의 형상으로 형성된다. 이 항균 포스트부(11)는 도 5의 (b)와 같이 커넥터(20)의 내부로 일정깊이 삽입가능한 지름을 갖는 것이 바람직하다. 또한 항균 포스트부(11) 및/또는 항균 밀폐부(12)는 저밀도 폴리에틸렌(Low-density polyethylene, LDPE)에 클로르헥시딘(chlorhexidine), 은(銀), 및 모란뿌리 추출물 중 어느 하나의 항균 물질을 함유하는 재질로 이루어 진다(컴파운드 제조방식). Here, the antibacterial sealing part 12 has a wider diameter than the antibacterial post part 11 and is formed in the shape of a cylinder having a diameter that expands downward. In addition, the antibacterial post part 11 is formed in the shape of a cylinder having the same diameter as the antibacterial sealing part 12 . As shown in FIG. 5(b), the antibacterial post part 11 preferably has a diameter capable of being inserted into the connector 20 at a certain depth. In addition, the antibacterial post part 11 and / or the antibacterial sealing part 12 contains an antibacterial substance of any one of chlorhexidine, silver, and peony root extract in low-density polyethylene (LDPE) (compound manufacturing method).

예를 들어 항균 포스트부(11) 및/또는 항균 밀폐부(12)를 저밀도 폴리에틸렌(LDPE)에 대해 클로르헥시딘 또는 은(Ag+)을 2중량부로 혼합한 컴파운드로 제조될 수 있다. 도 6의 (a)와 같은 항균 시험에서 항균 캡의 일부(1g)에 시험용액(대장균)을 1h동안 접촉한 경우 대략 60%의 항균성능을 보였다. For example, the antibacterial post part 11 and/or the antibacterial seal part 12 may be made of a compound obtained by mixing 2 parts by weight of chlorhexidine or silver (Ag + ) with respect to low density polyethylene (LDPE). In the antibacterial test as shown in (a) of FIG. 6, when the test solution (E. coli) was contacted with a portion (1g) of the antibacterial cap for 1h, about 60% of the antibacterial performance was shown.

또한 항균 포스트부(11) 및/또는 항균 밀폐부(12)를 저밀도 폴리에틸렌(LDPE)에 대해 모란뿌리 추출물을 0.2중량부로 혼합한 컴파운드로 제조한 경우에는, 대략 99% 이상의 항균성능을 보였다. 즉, 사출물 표면에서 모란뿌리 추출물의 항균제가 확산되면서 E. coli 균주가 초기(0H) 진탕 30sec부터 사멸하기 시작하여 1h에는 대부분 사멸하는 것을 확인되었다. In addition, when the antibacterial post part 11 and/or the antibacterial sealing part 12 were made of a compound in which 0.2 parts by weight of peony root extract was mixed with low density polyethylene (LDPE), the antibacterial performance was about 99% or more. That is, as the antibacterial agent of the peony root extract spreads on the surface of the injection product, it was confirmed that E. coli strains began to die from 30 sec of shaking at the initial (0H) and most of them died at 1h.

한편, 항균/항혈전 코팅층이 항균 포스트부(11) 및/또는 항균 밀폐부(12)에 제공될 수 있다(코팅방식). Meanwhile, an antibacterial/antithrombotic coating layer may be provided on the antibacterial post part 11 and/or the antibacterial sealing part 12 (coating method).

구체적으로 항균/항혈전 코팅층은, 클로로헥시딘과 메타크릴로일옥시에틸 포스포릴콜린-부틸메타크릴레이트 공중합체를 유기용매에 용해시킨 항균 및 항혈전 코팅용액을 제조한 다음, 상기 항균 및 항혈전 코팅용액에 안전 캡(10)의 전체 또는 항균 포스트부(11) 및/또는 항균 밀폐부(12)에만 침지한 후 건조시켜서 형성될 수 있다. 여기서 항균제는 코팅용액 총 중량 대비 0.01 내지 1.0 중량부로 포함될 수 있다. Specifically, for the antibacterial/antithrombotic coating layer, an antibacterial and antithrombotic coating solution is prepared by dissolving chlorhexidine and methacryloyloxyethyl phosphorylcholine-butyl methacrylate copolymer in an organic solvent, and then the antibacterial and antithrombotic coating solution is prepared. It may be formed by immersing the entirety of the safety cap 10 or only the antibacterial post portion 11 and/or the antibacterial sealing portion 12 in the antithrombotic coating solution and then drying. Here, the antimicrobial agent may be included in an amount of 0.01 to 1.0 parts by weight based on the total weight of the coating solution.

이 경우에도 도 7과 같이 대조군의 경우 다수의 콜로니가 생성되었지만, 안전 캡의 항균 포스트에 코팅된 항균제의 영향으로 E. coli 균주가 초기(0H) 진탕 30초부터 사멸하기 시작하여 1시간(1H) 경과 시에 대부분 사멸하는 것을 확인할 수 있다(99% 이상). In this case, as shown in FIG. 7, a large number of colonies were generated in the control group, but due to the effect of the antibacterial agent coated on the antibacterial post of the safety cap, the E. coli strain started to die from 30 seconds of shaking at the initial (0H) time and continued for 1 hour (1H). ), it can be confirmed that most of them die during the passage (more than 99%).

이상에서는 본 발명을 특정의 실시예에 대해서 도시하고 설명하였지만, 본 발명은 상술한 실시예에만 한정되는 것은 아니며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 이하의 청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어나지 않는 범위에서 얼마든지 다양하게 변경하여 실시할 수 있을 것이다. In the above, the present invention has been shown and described with respect to specific embodiments, but the present invention is not limited to the above-described embodiments, and those skilled in the art to which the present invention pertains will find the present invention described in the claims below. Various changes can be made without departing from the gist of the technical idea of the invention.
