The present invention relates to a drainage tube having a novel fixation structure in which skin tagging is not required. The present invention relates to a drainage tube having an inflatable fixed structure, wherein the drainage tube includes: an inflatable fixing portion which surrounds a portion of the drainage tube buried in a human body when inserted and is inflated by a fluid supplied from the outside; and a fluid channel including a fluid supply tube of which a distal part is connected to the inside of the inflatable fixing portion to supply and discharge a fluid to the inflatable fixing portion and a proximal part is exposed to the outside of the human body at the time of insertion of the drainage tube. According to the drainage tube of the present invention, the drainage tube is tightly fixed to the inside of a human body by the inflating of the inflatable fixing portion inserted into the human body. Thus, it is possible to conveniently perform drainage tube operation and recovery without causing additional wounds other than minimal perforation for insertion of the drainage tube, and without using a separate fixing member.

Description

팽창식 고정구조를 가지는 배액관{Drainage tube with inflatable fixing structure}Drainage tube with inflatable fixing structure

본 발명은 피부고정(tagging)이 필요 없는 새로운 고정구조를 가지는 배액관에 관한 것이다. The present invention relates to a drainage tube having a new fixing structure that does not require skin tagging.

수술 후 체내 수술부위 또는 이상이 있는 체내 조직에 혈액이나 장액, 농양 등의 체액이 고이게 되면 염증 등의 합병증을 유발하기 때문에 이를 강제적으로 배출하기 위하여, 일측 일부가 인체 내에 삽입되고, 타측은 인체 외부로 노출된 상태로 체내에 발생하는 체액을 외부로 배출시키기 위한 배액관을 삽입하는 시술이 널리 사용되고 있다.After surgery, if blood, intestinal fluid, or abscess, etc. collects in the body tissue at the surgical site or in an abnormal body tissue, it causes complications such as inflammation. A procedure in which a drainage tube is inserted for discharging the body fluid generated in the body to the outside in a state of being exposed to the skin is widely used.

이때 원하는 위치에 삽입된 배액관이 체외로 뽑히거나 밀려들어가지 않도록 피부에 고정하는 과정이 필요한데, 종래 배액관을 고정하는 방법으로, 봉합사를 이용하여 피부에 묶어두는(tagging) 방법, 피부용 스테플러로 고정하는 방법, 소정의 점착성부재로 배액관을 피부에 부착하는 방법 등이 이용되고 있다.At this time, it is necessary to fix the drainage tube inserted in the desired position to the skin so that it is not pulled out or pushed outside the body. Method, a method of attaching a drainage tube to the skin with a predetermined adhesive member, etc. are used.

봉합사를 이용하여 배액관을 피부에 묶어두는 방법(도 1a 참조)은, 배액관에 봉합사로 매듭을 형성하여 피부에 고정하는 것으로써, 시술이 번거롭고 비교적 오래 걸리며 시술자의 숙련도에 따라 고정방법, 고정강도 등이 각각 다르다는 문제가 있다. 또한 배액관을 유지하는 과정에서 환자의 움직임이나 장치 자체의 흔들림으로 피부의 고정부가 자극되어 짓무름, 피부 당김, 염증, 추가 상처, 흉터 등 부작용이 발생할 수 있다.The method of tying the drainage tube to the skin using a suture (see Fig. 1a) is to form a knot in the drainage tube with a suture and fix it to the skin, and the operation is cumbersome and takes a relatively long time. The problem is that each of these is different. In addition, in the process of maintaining the drainage tube, the fixed part of the skin is stimulated by the movement of the patient or the shaking of the device itself, which may cause side effects such as erosion, skin pulling, inflammation, additional wounds, and scarring.

피부용 스테플러를 사용하는 방법에는 다소 편리한 점이 있지만 배액관과의 결합을 위한 별도의 고정부재가 필요하고 피부에 충분하게 고정하기 쉽지 않으며, 역시 피부에 추가적인 상처와 흉터를 유발하는 단점이 있다(등록특허 10-1368368).Although the method of using a skin stapler is somewhat convenient, it requires a separate fixing member for coupling with the drainage tube and is not easy to sufficiently fix to the skin, and also has the disadvantage of causing additional wounds and scars on the skin (Registered Patent 10) -1368368).

점착성부재를 이용하는 고정법이 등록실용신안 20-0489503 등에 제시되어 있다(도 1b 참조). 이 방법은 기본적으로 피부와 배액관에 동시에 점착성 부재를 부착하여 고정하는 것이다.A fixing method using an adhesive member is suggested in Registered Utility Model 20-0489503 and the like (see FIG. 1b). This method basically attaches and fixes the adhesive member to the skin and the drainage tube at the same time.

이 방법은 봉합사나 피부용 스테플러 이용법에 비해 추가적인 상처 등이 없고 상대적으로 편리하지만 시술과정에서 비교적 넓은 면적의 점착성 부착고정부에 배액관을 끼워서 체결하고 이면지를 벗겨서 정확한 위치에 부착하는 것이 그리 용이하지 않으며 환부가 완전히 건조한 상태가 아니라면 부착력이 떨어져 고정장치로서의 기능이 부족해진다는 단점이 있다. This method does not have additional wounds and is relatively convenient compared to using sutures or skin staplers, but it is not so easy to attach a drainage tube to a relatively large area of the adhesive attachment part during the procedure and remove the backing paper to attach it to the correct location. If it is not in a completely dry state, there is a disadvantage that the function as a fixing device is insufficient because the adhesive force is lowered.

이외에도 종래기술에 의한 배액관 고정법은 배액관 외주면과 천공된 피부 사이에 틈이 발생할 여지가 있어 체액 누수로 인한 감염 발생, 공기 침투로 인한 폐기종 유발 등의 위험성이 상존한다.In addition, in the drainage tube fixation method according to the prior art, there is a possibility that a gap may occur between the outer peripheral surface of the drainage tube and the perforated skin, so there is a risk of infection caused by body fluid leakage, emphysema caused by air penetration, and the like.

또한 본 발명은 외부에 아무런 고정부재가 없더라도 고정할 수 있는 새로운 배액관을 제공하는 것을 목적으로 한다. Another object of the present invention is to provide a new drain pipe that can be fixed even if there is no fixing member on the outside.

또한 본 발명은 고정결과 자연스럽게 배액관 외주면과 천공된 피부 사이의 틈이 차단되는 새로운 배액관을 제공하는 것을 목적으로 한다. Another object of the present invention is to provide a new drainage tube in which the gap between the outer peripheral surface of the drainage tube and the perforated skin is naturally blocked as a result of fixing.

전술한 목적을 달성하기 위한 본 발명은, 원위부가 체내에 경피적으로 삽입되어 체액을 배출하기 위한 배액관에 있어서, The present invention for achieving the above object, the distal part is percutaneously inserted into the body in the drainage tube for discharging body fluid,

삽입되었을 때 체내에 매립되는 배액관 부위를 감싸며 외부로부터 공급되는 유체에 의해 팽창되는 팽창고정부와, 상기 팽창고정부로의 유체 공급과 배출을 위해 원위부가 상기 팽창고정부 내부에 연결되고, 근위부가 배액관 삽입시 체외에 노출되는 유체공급관을 포함하는 유체채널;을 포함하는 팽창식 고정구조를 가지는 배액관인 것을 특징으로 한다.An expansion fixing part that surrounds the drainage tube part embedded in the body when inserted and is expanded by a fluid supplied from the outside, and a distal part is connected to the inside of the expansion fixing part for fluid supply and discharge to the expansion fixing part, and a proximal part is a drainage tube It is characterized in that it is a drainage tube having an inflatable fixing structure including; a fluid channel including a fluid supply tube exposed to the outside of the body when inserted.

이상과 같이 본 발명에 의하면 팽창고정부의 팽창에 의해 배액관이 체내에 밀착 고정되므로 배액관 삽입을 위한 최소한의 천공 이외의 추가적 창상의 발생 없이, 그리고 별도의 고정부재 없이 간편하게 배액관 시술과 회수를 할 수 있게 된다.As described above, according to the present invention, since the drainage tube is fixed in close contact with the body by the expansion of the expansion fixing part, it is possible to conveniently perform the drainage tube operation and recovery without the occurrence of additional wounds other than the minimum perforation for insertion of the drainage tube and without a separate fixing member. there will be

또한 본 발명에 의하면 팽창고정부의 팽창에 의해 배액관이 체내에 밀착 고정되므로 팽창고정부의 팽창이 유지되는 동안에는 상당한 정도의 배액관의 밀림이나 당김이 있어도 배액관이 밀려들어가거나 빠져나오지 않아 불측의 의료사고 발생이 방지된다.In addition, according to the present invention, since the drainage tube is fixed in close contact with the body by the expansion of the expansion fixing part, even if there is a significant amount of pushing or pulling of the drainage tube while the expansion of the expansion fixing part is maintained, the drainage tube is not pushed in or out, so an unexpected medical accident occurrence is prevented.

However, the accompanying drawings are only examples for easily explaining the content and scope of the technical idea of the present invention, and thereby the technical scope of the present invention is not limited or changed. It will be natural for those skilled in the art that various modifications and changes are possible within the scope of the technical spirit of the present invention based on these examples.

이해의 편의를 위해, 배액관이 환자의 몸에 시술되었을 때 구성요소 중 체내에 가깝게 위치하는 쪽을 '원위(distal)', 체외 쪽을 '근위(proximal)'로 칭하기로 한다.For convenience of understanding, when the drainage tube is operated on the patient's body, the side that is located close to the body among the components will be referred to as 'distal', and the side outside the body will be referred to as 'proximal'.

본 발명에서 '배액관'은 '액체(체액)'를 체외로 배출하는 것을 상정하고 설명되겠지만, 액체 뿐만 아니라 체내의 기체를 배기하기 위해 사용될 수도 있다.In the present invention, the 'drain tube' will be described assuming that 'liquid (body fluid)' is discharged outside the body, but it may be used to exhaust not only the liquid but also the gas in the body.

전술하였듯이 본 발명은, 팽창고정부(10)와 유체채널(20)을 포함하는 팽창식 고정구조를 가지는 배액관에 관한 것이다. 팽창고정부(10)가 부분적으로 팽창된 상태의 배액관 개념적 입체도 및 팽창고정부(10) 전후의 개념적 단면도를 도 2a, 2b에 도시하였다. 도 2b에는 유체채널(20)의 도시가 생략되어 있다.As described above, the present invention relates to a drainage tube having an inflatable fixing structure including an expansion fixing part 10 and a fluid channel 20 . A conceptual three-dimensional view of the drainage tube in a state in which the expansion fixing unit 10 is partially inflated and a conceptual cross-sectional view before and after the expansion fixing unit 10 are shown in FIGS. 2A and 2B . The illustration of the fluid channel 20 is omitted in FIG. 2B .

도면에서 볼 수 있듯이 본 발명에 의한 배액관에서 팽창고정부(10)는, 배액관이 체내에 삽입(시술)되었을 때 체내에 매립되는 배액관 부위를 감싸며 양단이 배액관의 외면에 밀봉결합되어 있어 유체채널(20)을 통해 외부로부터 공급되는 유체에 의해 팽창되는 일종의 풍선이다. 팽창고정부(10)는 팽창력이 우수하며 안전성이 확인된 의료용 실리콘재질로 제작되는 것이 바람직하다. As can be seen in the drawing, in the drainage tube according to the present invention, the expansion fixing part 10 surrounds the drainage tube portion that is embedded in the body when the drainage tube is inserted (processed) into the body, and both ends are sealed to the outer surface of the drainage tube, so that the fluid channel ( 20) It is a kind of balloon that is inflated by the fluid supplied from the outside. It is preferable that the expansion fixing part 10 is made of a medical silicone material that has excellent expansion power and safety has been confirmed.

배액관이 삽입되었을 때 팽창고정부(10)는 온화한 체내에 위치하기 때문에 팽창되었을 때 이를 파손할 만한 외력이 작용할 여지가 거의 없으므로 매우 얇게 제작될 수 있다. 따라서 팽창고정부(10)가 팽창되지 않았을 때 팽창고정부(10)에 의해 배액관의 외관(부피)은 통상의 배액관의 외관과 거의 같다.When the drainage tube is inserted, since the expansion fixing part 10 is located in a mild body, there is little room for external force to damage it when inflated, so it can be manufactured very thinly. Therefore, when the expansion fixing part 10 is not expanded, the external appearance (volume) of the drainage pipe by the expansion fixing part 10 is almost the same as that of a normal drainage pipe.

상기 팽창고정부(10)에 유체가 공급될 때 원위부 쪽부터 팽창되는 것이 쐐기효과에 더 바람직하다. 이를 위해 도 2a, 2b에 도시된 것처럼 ① 상기 팽창고정부(10)의 원위부측의 두께가 근위부측의 두께보다 얇게 형성되도록 하거나, ② 상기 유체채널(20) 유체공급관(21)의 원위부(말단)가 상기 팽창고정부(10)의 원위부측에 위치되도록 하는 것이 바람직하다. It is more preferable for the wedge effect to expand from the distal side when the fluid is supplied to the expansion fixing part 10 . For this purpose, as shown in FIGS. 2a and 2b, ① the distal part of the expansion fixing part 10 is formed to have a thinner thickness than the proximal part, or ② the distal part (end of the fluid channel 20) fluid supply pipe 21. ) is preferably located on the distal side of the expansion fixing part (10).

상기 유체채널(20)은, 상기 팽창고정부(10)로의 유체 공급과 배출을 위해 원위부가 상기 팽창고정부(10) 내부에 연결되고, 근위부가 배액관 삽입시 체외에 노출되는 유체공급관(21)을 포함하는데, 이를 통해 유체가 팽창고정부(10)로 공급되거나 배출된다. The fluid channel 20 has a distal part connected to the inside of the expansion fixing part 10 for supplying and discharging fluid to and from the expansion fixing part 10, and a fluid supply pipe 21 through which the proximal part is exposed to the outside of the body when the drainage tube is inserted. It includes, through which the fluid is supplied or discharged to the expansion and fixing unit (10).

유체채널(20) 유체공급관(21)의 근위부에는 유체의 공급과 회수를 위한 소정의 유체공급기구(22)(예를 들면, 주사기 또는 펌프)가 장착될 수 있는데, 도 2a에는 유체공급기구(22)로 주사기가 도시되었다.A predetermined fluid supply mechanism 22 (for example, a syringe or a pump) for supply and recovery of a fluid may be mounted at a proximal portion of the fluid channel 20 and the fluid supply pipe 21. In FIG. 2A, the fluid supply mechanism ( 22), the syringe is shown.

도 2a에는 유체채널(20)의 유체공급관(21) 원위부가 팽창고정부(10)의 원위부에 연결되고 배액관과는 독립적으로 형성된 예가 되어 있는데, 유체공급관(21)이 배액관의 외면이나 중간 또는 내측면에 결합된 상태로 일체로 형성될 수도 있을 것이다. 2a shows an example in which the distal part of the fluid supply pipe 21 of the fluid channel 20 is connected to the distal part of the expansion and fixation part 10 and is formed independently of the drainage pipe. It may be integrally formed in a state coupled to the side.

이러한 본 발명에 의한 배액관의 사용과정을 도 3을 참조하여 설명한다. The process of using the drain pipe according to the present invention will be described with reference to FIG. 3 .

먼저, 통상의 방법과 동일하게 본 발명에 의한 배액관을 인체에 삽입한다(도면에서 (가)). 이어서 외부의 소정의 공급장치에 의해 유체가 유체채널(20)을 통해 공급되면 팽창고정부(10)가 서서히 팽창하는데, 본 발명의 일 실시예에 의하면 팽창고정부(10)가 원위부에서 근위부로 팽창하면서 (나), 피하조직층 아래까지 충분하게 팽창하게 된다(다). 이렇게 팽창된 팽창고정부(10)는 그와 접촉되는 조직과의 마찰효과 및 쐐기효과에 의해 고정되므로 결국 배액관 자체가 완전하게 고정되는 효과를 얻게 된다.First, the drainage tube according to the present invention is inserted into the human body in the same manner as in a conventional method ((a) in the drawing). Then, when the fluid is supplied through the fluid channel 20 by a predetermined external supply device, the expansion fixing part 10 is gradually expanded. According to an embodiment of the present invention, the expansion fixing part 10 is moved from the distal part to the proximal part. while expanding (B), it expands sufficiently below the subcutaneous tissue layer (C). The expansion and fixation part 10 thus expanded is fixed by the friction effect and the wedge effect with the tissue in contact with it, so that the drainage tube itself is completely fixed.

본 발명에 의하면, 예를 들면 소정의 압력이 되도록 유체를 주입하면 팽창할 수 있는 공간에 맞추어 팽창고정부(10)가 충분히 팽창하게 된다. 따라서 얇은 피하조직을 가지는 마른 환자나 두꺼운 피하조직을 가지고 있는 살찐 환자에 따라 팽창정도를 조절함으로써 배액관 고정이 적절하게 이루어지게 된다.According to the present invention, for example, when a fluid is injected to a predetermined pressure, the expansion fixing unit 10 is sufficiently expanded to fit the expandable space. Therefore, by adjusting the degree of expansion according to a thin patient with thin subcutaneous tissue or a fat patient with thick subcutaneous tissue, the drainage tube is properly fixed.

일단 배액관이 삽입(시술)되면 상당한 기간동안 삽입된 상태가 유지되어야 한다. 따라서 일단 공급된 유체가 저절로 배출되는 것을 방지하기 위하여, 상기 유체채널(20) 유체공급관(21)의 근위부 부근에는 유체의 유입은 가능하지만 자연배출은 방지하는 체크밸브(23)가 장착되어 있는 것이 바람직하다. 유체채널(20)에 유체공급기구(22)가 추가된 경우 체크밸브(23)는 유체공급관(21)의 근위부와 유체공급기구(22) 사이에 위치하는 것이 바람직하다.Once the drainage tube is inserted (procedure), it must remain inserted for a considerable period of time. Therefore, in order to prevent the fluid once supplied from being discharged by itself, a check valve 23 is installed in the vicinity of the proximal portion of the fluid supply pipe 21 in the fluid channel 20 to allow the inflow of fluid but prevent natural discharge. desirable. When the fluid supply mechanism 22 is added to the fluid channel 20 , the check valve 23 is preferably located between the proximal portion of the fluid supply pipe 21 and the fluid supply mechanism 22 .

본 발명에서 사용되는 유체는, 취급이 용이한 공기인 것이 바람직한데, 공기 대신에 살균된 생리식염수를 유체로 사용할 수도 있을 것이다.The fluid used in the present invention is preferably air that is easy to handle, but sterilized physiological saline may be used as the fluid instead of air.

본 발명에 의한 팽창식 고정구조를 가지는 배액관에 의하면 체내에서 체외로 고정효과를 얻을 수 있지만, 체외에서 체내로 빨려들어가는 것을 방지하기 위하여 상기 팽창고정부(10)가 적절하게 팽창하였을 때 피부들 사이로 외부에서 배액관을 고정하는 다양한 외부고정부재(30)를 추가할 수 있다. According to the drainage tube having an inflatable fixing structure according to the present invention, it is possible to obtain a fixing effect from the body to the outside of the body, but when the expansion and fixing part 10 is properly inflated in order to prevent being sucked into the body from outside the body, it is inserted between the skins. Various external fixing members 30 for fixing the drain pipe from the outside can be added.

본 발명에서 상기 외부고정부재(30)는, 도 4a에 도시된 것처럼, 배액관을 전체적으로 또는 부분적으로 내장하면서 피부에 밀착되는 제1고정부(31)와, 상기 제1고정부(31)에 가압결합하여 제1고정부(31)와 배액관이 밀착고정 되도록 하는 제2고정부(32)로 이루어질 수 있다. 제2고정부(32)는 상처 주변에서 나오는 삼출물이나 혈액 등이 고정부들 사이에서 고여있지 않고 외부 드레싱 재료로 흡수 또는 이동이 용이하도록 타공되어 있는 것이 바람직하다.In the present invention, the external fixing member 30 is pressed against the first fixing part 31 and the first fixing part 31, which are in close contact with the skin while completely or partially embedding the drainage tube, as shown in FIG. 4a. It may be formed of a second fixing part 32 that is coupled to the first fixing part 31 and the drain pipe to be in close contact with each other. It is preferable that the second fixing part 32 is perforated so that exudate or blood coming out from the wound does not accumulate between the fixing parts and is easily absorbed or moved by the external dressing material.

이러한 상기 외부고정부재(30)가 배액관에 장착된 상태도를 도 4b에 도시하였다.A state diagram in which the external fixing member 30 is mounted to the drain pipe is shown in FIG. 4B .

외부고정부재(30)가 적용되는 경우, 배액관은 피부(+피하조직층)를 중심으로 체내에서는 팽창고정부(10)에 의해, 피부 외부 표면에서는 외부고정부재(30)에 의해 이중으로 고정된다.When the external fixing member 30 is applied, the drainage tube is double fixed by the expansion fixing part 10 in the body around the skin (+ subcutaneous tissue layer) and by the external fixing member 30 on the outer surface of the skin.
