Description

혈액누출조절이 가능한 카테터Catheter with adjustable blood leakage

본 발명은 혈액누출조절이 가능한 카테터장치에 관한 것으로, 좀더 상세하게는 혈관으로부터 카테터를 통하여 누출되는 혈액의 양을 조절할 수 있도록 하여 혈액이 외부로 누출되어나오는 것을 방지할 수 있도록 하여 혈액이 외부로 누출되어나오는 것을 방지할 수 있도록 하고, 주사기나 수액세트 등을 카테터와 보다 손쉽게 결합할 수 있도록 한 혈액누출조절이 가능한 카테터장치에 관한 것이다.The present invention relates to a catheter device capable of controlling blood leakage, and more particularly, to adjust the amount of blood leaking through the catheter from the blood vessel to prevent blood from leaking to the outside to prevent blood from leaking to the outside. The present invention relates to a catheter device capable of controlling blood leakage to prevent leakage, and to more easily combine a syringe or a set of fluid with a catheter.

일반적으로 경피적(percutanious)으로 혈관에 삽입하는 카테터(Catheter)는 먼저 혈관에 주사바늘과 같이 삽입된 다음 삽입된 주사바늘을 빼낸 후 혈관으로부터 혈액을 추출하기 위한 장치이다.Generally, a catheter inserted into a blood vessel percutanious (Catheter) is a device for extracting blood from a blood vessel after first inserting a needle into a blood vessel and then removing the inserted needle.

이러한 경피적 혈관 카테터는 주사바늘이 착탈 가능하게 삽입되기 위한 삽입관과, 상기한 삽입관과 일체로 결합되고 주사바늘 몸체와 착탈 가능하게 결합되기 위하여 소정크기의 강성을 갖는 카테터를 포함한다.The percutaneous vascular catheter includes an insertion tube for detachably inserting the needle, and a catheter having a predetermined size of rigidity to be integrally coupled to the insertion tube and detachably coupled to the needle body.

이에 따라 경피적 혈관 카테터의 카테터로 주사바늘 몸체를 삽입하고, 삽입관으로 주사바늘을 삽입한 상태에서 주사바늘 및 삽입관을 함께 혈관속으로 삽입한 후, 상기한 주사바늘 및 주사바늘 몸체를 카테터의 외부로 빼내면 상기한 삽입관을 통하여 카테터로 혈액이 누출되는데, 이때 상기한 카테터에 주사기를 결합하면 주사기로 혈액을 뽑아내거나 혈액에 약물 또는 조영제를 주입하거나 수액세트 등을 결합하거나 하는 장치이다.Accordingly, the needle body is inserted into the catheter of the percutaneous vascular catheter, the needle and the insertion tube are inserted into the blood vessel together with the needle inserted into the insertion tube, and then the needle and the needle body are inserted into the catheter. The blood is leaked to the catheter through the insertion tube when it is pulled out to the outside, and when the syringe is coupled to the catheter, the blood is drawn out by the syringe, the drug or contrast agent is injected into the blood, or the fluid set is combined.

그러나 종래의 경피적 혈관 카테터의 카테터는 소정크기의 강성을 갖는 재질로 제작되고, 혈관으로부터 샘플링 관으로 누출되는 혈액의 량을 조절할 수 있는 별도의 수단이 마련되어 있지 않았으므로 혈관에 삽입된 주사바늘을 카테터로부터 빼내게 되면 상대적으로 높은 압력을 갖는 혈액이 카테터 외부로 급격하게 누출되어 나올 수 있게 됨과 아울러 사용자의 피부에 혈액이 묻게 되면 간염이나 에이즈등 각종질병이 감염될 수 있게 되는 문제점이 있었다.However, the catheter of the conventional percutaneous vascular catheter is made of a material having a predetermined size of rigidity, and since there is no separate means for controlling the amount of blood leaking from the blood vessel to the sampling tube, the catheter is inserted into the blood vessel. When extracted from the blood that has a relatively high pressure can be rapidly leaked out of the catheter and when the blood on the user's skin there was a problem that can be infected with various diseases such as hepatitis or AIDS.

특히 동맥과 같이 혈액의 압력이 높은 경우 혈액이 카테터로부터 더욱 급격하게 튀어나오게 되어 상기와 같은 문제점이 더욱 내재되어 있었다.In particular, when the pressure of the blood is high, such as an artery, the blood protrudes more rapidly from the catheter, and the above problems are more inherent.

또한 동맥이나 정맥 천자 후 혈액의 누출을 방지하기 위하여 흔히 사용하는 방법은 천자 후 한손으로 카테터의 선단을 눌러서 피가 누출되지 않게 하는 것이나 이 방법은 항상 성공하지는 못하므로 혈액이 피시술자의 피부에 오염될 가능성은 계속 존재하며 한손은 선단을 누르는데 사용하고 있으므로 경피적 혈관 카테터에 주사기나 수액세트를 연결하고자 할 경우 나머지 한손만으로는 연결이 힘드므로 다른 사람의 도움을 받아야 하는 어려움이 있다.In addition, the common method to prevent blood leakage after arterial or venous puncture is to press the tip of the catheter with one hand after puncture so that no blood is leaked. However, this method is not always successful. The possibilities still exist, and one hand is used to press the tip, so if you want to connect a syringe or a set of fluid to a percutaneous vascular catheter, the other hand is difficult to connect, so you have to get help from others.

따라서 본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 혈관으로부터 샘플링 관으로 누출되는 혈액의 양을 조절할 수 있도록 하여 혈액이 외부로 급격하게 튀어나오는 것을 방지할 수 있도록 하고, 주사기나 수액세트 등을 카테터와 보다 손쉽게 결합할 수 있도록 한 혈액누출조절이 가능한 카테터를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention to control the amount of blood leaking from the blood vessel to the sampling tube to prevent the blood from popping out to the outside, It is to provide a catheter that can control blood leakage, which makes it easier to combine a syringe or a set of fluid with a catheter.

상기의 목적을 달성하기 위하여 본 발명은, 주사바늘이 착탈 가능하게 삽입되고 이 주사바늘과 함께 혈관에 삽입되기 위한 삽입부재와; 상기한 삽입부재와 일체로 결합되고 상기한 혈관으로부터 혈액을 추출하거나 주사기나 수액세트와 연결하여 약물을 주입하는 카테터와; 상기한 카테터와 소정크기의 간격을 두고 배치되고 주사바늘 몸체가 착탈가능하게 결합되기 위한 결합부재와; 상기한 카테터와 결합부재의 사이로 배치되고 혈관으로부터 삽입부재를 통하여 추출되는 혈액의 양을 사용자가 외부에서 확인하면서 임의로 조절하기 위한 누출양조절수단을 포함한다.In order to achieve the above object, the present invention, the needle is detachably inserted and the insertion member for insertion into the blood vessel with the needle; A catheter coupled to the insertion member integrally and extracting blood from the blood vessel or connecting with a syringe or an infusion set to inject a drug; A coupling member disposed at an interval of the catheter and a predetermined size and to which the needle body is detachably coupled; It is disposed between the catheter and the coupling member and includes a leak amount adjusting means for arbitrarily adjusting the amount of blood extracted from the blood vessel through the insertion member by the user.

이에 따라 주사바늘 및 삽입부재가 혈관속에 삽입되면, 주사바늘 및 주사바늘 몸체를 삽입부재 및 결합부재로부터 빼내고, 누출양조절수단을 누르고 있는 힘을 약간 폴어주면 혈관으로부터 혈액이 삽입부재 및 카테터를 통하여 누출양조절수단으로 누출된다.Accordingly, when the needle and the insertion member are inserted into the blood vessel, the needle and the needle body are removed from the insertion member and the coupling member, and when the force holding the amount of leakage control is slightly released, blood from the blood vessel passes through the insertion member and the catheter. Leakage by leak amount control means.

이때, 상기한 누출 양조절수 단을 누르고 있는 힘의 크기를 조절하여 혈관으로 부터 누출양조절수단으로 누출되는 혈액의 양을 조절할 수 있게 됨은 물론 누출되는 혈액의 양을 보고 삽입부재가 정확하게 혈관속에 삽입되었는가를 용이하게 판단할 수 있게 되고 아울러 동맥 천자 후 혈액의 누출을 방지하기 위하여 카테터의 선단을 눌러주고 있던 손이 이 장치를 사용할 경우 누출을 조절하기 위하여 카테터의 허브(hub;뒷부분에 있는 주사기와 연결되는 부분)를 잡고 있으므로 다른사람의 도움 없이도 다른 한손을 사용하여 주사기나 수액세트를 허브와 손쉽게 결합시킬 수 있는 것이다.At this time, the amount of blood leaking from the blood vessel to the amount of blood leaking from the blood vessel can be adjusted by adjusting the magnitude of the force holding the leak volume adjusting stage, and the insertion member is accurately inserted into the blood vessel by looking at the amount of blood leaking. In addition, the hand holding the catheter's tip to prevent blood leakage after arterial puncture can be easily determined, and the catheter's hub and the syringe This allows you to easily combine a syringe or a set of fluid with the hub using the other hand without the help of another person.
