Description
본 발명은 케모포트와 케모포트의 위치를 식별하는 방법에 관한 것으로서, 특히 외부 신호를 받으면 발광하는 발광물질을 외측면에 도포한 케모포트와 발광물질이 도포된 케모포트에 외부 신호를 주어 발광물질을 발광시켜 피부 밑에 이식된 캐모포트의 위치를 식별할 수 있는 방법을 제공하는 데 그 목적이 있다.The present invention relates to a chemoport and a method for identifying the position of the chemoport, and more particularly, to a chemoport having a luminescent material applied to the outer surface thereof that emits light when receiving an external signal, and a method for identifying the position of a chemoport implanted under the skin by applying an external signal to the chemoport having the luminescent material applied thereto to cause the luminescent material to emit light.
케모포트(Chemoport)는 포털(portal)과 카테터(cathertor)로 구성된 중심 정맥관의 일종이다.A chemoport is a type of central venous line consisting of a portal and a catheter.
케모포트는 항암제와 같은 약물을 주입하거나 수혈 및 채혈을 위해 인체 내에 삽입되는 장치로서, 항암제, 항생제, 혈액제제, 비경구적 영양공급, 수액, 진통제의 간헐적이거나 계속적인 주입이 필요하거나, 말초혈관 확보의 어려움이 있거나, 가정이나 의료기관에서 장기간 치료를 받아야 하는 대상(환자)에게 주로 삽입되고 있다.A chemoport is a device inserted into the human body to inject drugs such as anticancer drugs or for blood transfusions and blood collection. It is mainly inserted for patients who require intermittent or continuous infusion of anticancer drugs, antibiotics, blood products, parenteral nutrition, fluids, or analgesics, have difficulty securing peripheral blood vessels, or require long-term treatment at home or in a medical institution.
또한 종래의 케모포트는 외관상 잘 보이지 않고, 미사용시 소독이 불필요하며, 수영 또는 목욕이 가능하고, 수개월에서 수년 동안 사용이 가능한 장점이 있다. 한편 케모포트의 포털 부위는 몸속(피하)에 위치하고, 카테터는 동·정맥의 혈관 내로 삽입되어, 외부로 노출되는 부분이 없어 혈류 감염의 발생이 낮아 장기유치용 혈관 내 카테터로서 활용되고 있다.In addition, conventional chemoports have the advantages of being invisible in appearance, not requiring disinfection when not in use, being able to swim or bathe, and being usable for several months to several years. Meanwhile, the portal area of the chemoport is located inside the body (subcutaneously), and the catheter is inserted into the blood vessels of the arteries and veins, so there is no part exposed to the outside, and the occurrence of bloodstream infection is low, so it is used as a long-term intravascular catheter.
구체적으로 케모포트와 같은 약물 주입 장치는 인체 내부에 이식되고 약물이 공급되는 챔버와, 챔버와 피하 정맥을 연결하는 카테터를 포함한다. 챔버는 셀프실링(Self sealing)되는 커버막으로 밀폐되며, 주사바늘로 커버막을 찔러 관통시킨 후 약물이 챔버 내측으로 공급되도록 한다.Specifically, a drug infusion device such as a chemoport includes a chamber that is implanted inside the human body and supplies drugs, and a catheter that connects the chamber to a subcutaneous vein. The chamber is sealed with a self-sealing cover membrane, and the drug is supplied into the chamber by piercing the cover membrane with a syringe needle.
한편, 이식된 챔버에 약물을 주입하는 과정을 보면, 일반적으로 시술자가 챔버가 이식된 부위를 육안으로 확인하여 챔버 주위를 손으로 잡고, 커버막의 위치를 짐작하여 주사바늘로 삽침하게 된다.Meanwhile, when looking at the process of injecting drugs into the transplanted chamber, the operator generally visually checks the area where the chamber is transplanted, holds the area around the chamber with his or her hand, guesses the location of the cover membrane, and then inserts the needle.
그러나, 이식된 챔버는 피부에 가려져서 육안으로 정확한 위치를 식별하기가 용이하지 않고, 커버막은 챔버보다 크기가 작아 주사바늘로 찔러야 하는 면적이 작기 때문에, 숙달된 시술자가 아닌 경우, 커버막에 정확하고 안전하게 주사바늘을 삽침하기 어려운 문제가 있다.However, since the transplanted chamber is covered by the skin, it is not easy to identify the exact location with the naked eye, and since the cover membrane is smaller than the chamber, the area that must be pierced with a needle is small, so it is difficult for a non-skilled practitioner to accurately and safely insert a needle into the cover membrane.
삽침이 정확하게 이루어지지 않을 경우, 독성이 강한 항암제가 피부 및 주변 조직으로 유출되고 이로 인해 항암제로 인한 조직의 손상 및 케모포트 제거 및 케모포트 재삽침, 항암치료 중단 등의 중대한 재해가 발생할 수도 있다.If the insertion is not done accurately, the highly toxic anticancer drug may leak into the skin and surrounding tissues, which may result in serious harm such as tissue damage caused by the anticancer drug, removal of the chemoport, reinsertion of the chemoport, and discontinuation of chemotherapy.
본 발명은 앞에서 설명한 바와 같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, 외부 신호를 받으면 발광하는 발광물질을 케모포트의 포털의 외측면에 부착 또는 코팅하고 피부 외측에서 외부 신호를 입력하여 발광물질을 발광시킴으로써, 케모포트의 포털 위치를 정확하게 확인할 수 있게 구성한 발광 케모포트 및 케모포트 위치 식별방법을 제공하는 데 그 목적이 있다.The present invention has been made to solve the problems of the prior art as described above, and the purpose of the present invention is to provide a luminescent chemoport and a method for identifying the location of the chemoport configured to accurately identify the portal location of the chemoport by attaching or coating a luminescent material that emits light when receiving an external signal to the outer surface of the portal of the chemoport and causing the luminescent material to emit light when an external signal is input from the outer side of the skin.
상기와 같은 목적을 달성하기 위한 본 발명에 따른 케모포트는 외부 조건신호에 의해 반응하는 반응물질이 포털에 위치하는 것을 기술적 특징으로 한다.The chemoport according to the present invention for achieving the above purpose has a technical feature in that a reactive substance that reacts to an external conditional signal is located in the portal.
또한, 본 발명의 바람직한 실시예에 따르면, 반응물질은 포털의 케이스 외주면에 위치한다.Additionally, according to a preferred embodiment of the present invention, the reactant is located on the outer surface of the case of the portal.

상기와 같은 목적을 달성하기 위한 본 발명의 케모포트 위치 식별방법은 외부 조건신호에 의해 반응하는 반응물질이 포털에 위치하며 피부 내에 이식된 케모포트에 외부 조건신호를 입력하는 단계를 포함하는 것을 기술적 특징으로 한다.The method for identifying a chemoport location of the present invention for achieving the above-described purpose is technically characterized by including a step of inputting an external conditional signal to a chemoport implanted in the skin, wherein a reactive substance that reacts to an external conditional signal is located at a portal.
또한, 본 발명의 바람직한 실시예에 따르면, 외부 조건신호는 적외선이며 반응물질은 헤모글로빈으로서, 적외선에 의해 헤모글로빈이 발광하는 단계를 더 포함한다.In addition, according to a preferred embodiment of the present invention, the external condition signal is infrared and the reactant is hemoglobin, and the method further includes a step of causing hemoglobin to emit light by infrared.
또한, 본 발명의 바람직한 실시예에 따르면, 외부 조건신호는 전기신호이며 반응물질은 압전체로서, 입력된 전기신호에 의해 압전체가 변형하는 단계를 더 포함한다.In addition, according to a preferred embodiment of the present invention, the external condition signal is an electric signal, the reactant is a piezoelectric body, and the step of deforming the piezoelectric body by the input electric signal is further included.

아래에서는 본 발명에 따른 케모포트 및 케모포트 위치 식별방법의 양호한 실시예를 첨부한 도면을 참조로 하여 상세히 설명한다.Below, preferred embodiments of a chemoport and a chemoport location identification method according to the present invention are described in detail with reference to the attached drawings.
혈액 내 헤모글로빈에 적외선을 조사하면, 헤모글로빈에서 적외선을 흡수하면서 발광한다. When infrared rays are irradiated on hemoglobin in the blood, hemoglobin absorbs the infrared rays and emits light.
본 발명은 적외선과 같은 외부 조건신호에 반응하는 헤모글로빈과 같은 반응물질을 케모포트의 포털 외주면에 부착 또는 도포함으로써, 외부 조건신호를 케모포트 포털에 입력하면 포털에 부착 또는 도포된 반응물질이 반응하여 포털의 정확한 위치를 피부 외부에서 인식할 수 있게 구성한 것이다. The present invention is configured such that by attaching or applying a reactive substance, such as hemoglobin, which reacts to an external conditional signal, such as infrared, to the outer surface of a portal of a chemoport, when an external conditional signal is input to the chemoport portal, the reactive substance attached or applied to the portal reacts, thereby enabling the exact location of the portal to be recognized from outside the skin.
이처럼 케모포트의 포털 및 포털의 챔버의 위치를 정확하게 인식할 수 있다면 삽침 시에 발생하는 오류를 줄일 수 있다는 효과가 있다.If the location of the portal and chamber of the portal of the chemoport can be accurately recognized in this way, it has the effect of reducing errors that occur during insertion.
도면에서, 도 1은 케모포트를 나타낸 사시도이고, 도 2는 케모포트의 포털을 피부 아래에 이식한 상태를 나타낸 개념도이며, 도 3은 적외선을 조사하여 포털에서 빛이 형성되는 관계를 나타낸 개념도이다.In the drawings, Fig. 1 is a perspective view showing a chemoport, Fig. 2 is a conceptual diagram showing a state where the portal of the chemoport is implanted under the skin, and Fig. 3 is a conceptual diagram showing the relationship in which light is formed in the portal by irradiating infrared rays.
도 1 내지 도 3에 도시된 바와 같이, 케모포트(100)의 포털(110)의 케이스(111) 외주면에는 외부 조건신호 즉 적외선에 발광하는 반응물질인 헤모글로빈을 도포된 반응층(120)이 형성된다. 이때 포털(110)의 케이스(111) 중앙에 위치하는 챔버(113)에는 반응물질을 도포하지 않음으로써, 차후에 헤모글로빈이 발광할 때에 포털(110)의 위치를 인식할 수 있게 됨과 동시에 발광하지 않은 챔버(113)의 위치 또한 쉽게 인식할 수 있도록 구성한다.As shown in FIGS. 1 to 3, a reaction layer (120) is formed on the outer surface of the case (111) of the portal (110) of the chemoport (100), to which hemoglobin, a reaction material that emits light in response to an external condition signal, i.e., infrared light, is applied. At this time, the reaction material is not applied to the chamber (113) located in the center of the case (111) of the portal (110), so that the position of the portal (110) can be recognized when hemoglobin emits light in the future, and at the same time, the position of the chamber (113) that does not emit light can also be easily recognized.
반응물질은 케이스(111)의 외주면에 도포하는 것으로 설명하고 있으나, 이는 한 실시예일 뿐 반응물질이 인쇄된 스티커를 케이스(111)의 외주면에 부착할 수도 있다.Although the reactant is described as being applied to the outer surface of the case (111), this is only one example, and a sticker printed with the reactant may be attached to the outer surface of the case (111).
이처럼 포털 케이스(111)의 외부면에 반응물질을 도포한 반응층(120) 또는 스티커 형태로 고정하고, 삽침이 이루어지는 챔버(113)에는 반응물질이 도포되지 않게 함으로써, 피부(S) 밖에서 적외선 스캐너(130)로 적외선을 조사할 경우 피부(S)를 침투한 적외선이 반응물질로 입력되고, 입력된 적외선 즉 외부 조건신호에 의해 반응물질이 발광한다.In this way, by applying a reactive material to the outer surface of the portal case (111) and fixing it in the form of a reactive layer (120) or sticker, and not applying the reactive material to the chamber (113) where the insertion takes place, when infrared rays are irradiated from outside the skin (S) with an infrared scanner (130), the infrared rays penetrating the skin (S) are input as the reactive material, and the reactive material emits light by the input infrared rays, i.e., the external condition signal.
반응물질이 발광함에 따라 의료진은 포털(110)의 위치를 확인할 수 있으며, 환형으로 발광하는 반응물질의 안쪽 즉 반응물질이 없어 발광하지 않은 음영이 짙은 부위가 챔버(113)에 해당된다. As the reactant glows, the medical staff can identify the location of the portal (110), and the dark shaded area inside the annular glowing reactant, that is, the area that does not glow because there is no reactant, corresponds to the chamber (113).
의료진은 챔버(113)의 위치를 인식할 수 있게 됨에 따라 챔버(113)가 위치하는 쪽으로 주사바늘을 삽침하여 약제를 주입할 수 있게 된다.As the medical staff becomes able to recognize the location of the chamber (113), they can insert a needle into the direction where the chamber (113) is located to inject the drug.
앞서 설명한 본 발명의 한 실시예에 있어서, 적외선이 외부 조건신호이며 헤모글로빈은 발광하는 반응물질로 설명하고 있으나, 외부 조건신호와 반응물질은 다른 다양한 예로 구성할 수 있다. In one embodiment of the present invention described above, infrared rays are described as an external conditional signal and hemoglobin is described as a luminescent reactant, but the external conditional signal and the reactant can be composed of various other examples.
그 예로서, 전기적 외부 조건신호를 입력하면 전기신호에 의해 형태가 변형되는 압전체를 반응물질로 구성함으로써, 의료진은 시각 아닌 촉각으로 케모포트의 포탈 위치 및 챔버의 위치를 인식하게 구성할 수도 있다.For example, by configuring a piezoelectric material that changes shape due to an electric signal when an electrical external condition signal is input, the medical staff can be configured to recognize the portal location and chamber location of the chemoport by touch rather than sight.
본 발명은 다양한 외부 조건신호 중 어느 한 신호가 입력되면 포털 케이스에 장착된 반응물질이 반응하여 포털의 위치를 의료진이 인식할 수 있다는 개념을 기술적 범주라 할 수 있다.The present invention can be said to be a technical category of a concept in which a reactive material mounted on a portal case reacts when any one of various external condition signals is input, thereby allowing medical staff to recognize the location of the portal.
도면에는 도시하지 않았으나 본 발명의 기술적 범주에 포함된 다른 실시예에 대해 아래에서는 구체적으로 설명한다.Other embodiments that are not shown in the drawings but are included in the technical scope of the present invention are specifically described below.
챔버(113)는 삽침이 가능한 실리콘 재질로 구성될 수 있다. The chamber (113) may be made of a silicone material that allows insertion.
이때 챔버(113)를 적외선에 반응하는 실리콘(반응물질)으로 구성할 경우 피부(S) 밖에서 적외선 스캐너(130)로 적외선을 조사하면, 챔버가 발광하게 되고 의료진은 발광하는 챔버(113)를 확인하고 챔버(113)에 정확한 삽침이 가능하게 된다.At this time, if the chamber (113) is composed of silicon (a reactive material) that reacts to infrared rays, when infrared rays are irradiated from outside the skin (S) with an infrared scanner (130), the chamber glows, and the medical staff can confirm the glowing chamber (113) and accurately insert the device into the chamber (113).
이처럼 본 발명의 케모포트 및 케모포트 위치 식별방법은 삽침되는 챔버의 위치를 의료진이 정확하게 인식할 수 있도록 포털(110) 또는 챔버(113)에 반응물질을 위치하여 챔버(113)의 위치를 인식할 수 있도록 구성하는 것이다.In this way, the chemoport and chemoport location identification method of the present invention is configured to position a reactive substance in a portal (110) or chamber (113) so that medical staff can accurately recognize the location of the chamber to be inserted, thereby recognizing the location of the chamber (113).
