동맥과 정맥 식별이 용이한 주사바늘구조{make arterial and vein identification a breeze injection needle structure}Make arterial and vein identification a breeze injection needle structure}

본 발명은 동맥과 정맥 식별이 용이한 주사바늘구조에 관한 것이다.The present invention relates to a needle structure for easy identification of arteries and veins.

혈관은 모양과 크기와 흐름에 따라 동맥과 정맥 모세혈관으로 구분되며,동맥은 벽이 두껍고 견고하며, 혈관의 박동이 촉지되나,정맥에서는 벽이 얇고 연약하다. Blood vessels are divided into arteries and venous capillaries according to their shape, size, and flow. Arteries are thick and solid in wall, and palpable pulsation of veins, but thin and weak in veins.

동맥과 정맥은 모두 내막, 중막, 외막의 3층으로 되어 있으나, 동맥에서는 특히 중막의 평활근과 탄성섬유가 정맥에 비하여 훨씬 풍부한 것은 동맥벽이 박동성의 혈류와 혈압에 견딜 수 있도록 하기 위한 것이다.Arteries and veins are composed of three layers of inner, middle, and outer membranes. However, the arteries are particularly rich in medial smooth muscles and elastic fibers in order to allow the arterial wall to withstand pulsating blood flow and blood pressure.

기초적으로 혈관의 종류를 식별하는 방법으로는 손등 위의 푸른 혈관은 정맥이나, 손목에서 맥박이 잡히는 부위는 동맥으로서, 주사맞고 수혈하고 채혈하는 것은 모두 정맥에서 이루어진다.Basically, the blue blood vessel on the back of the hand is a vein, but the place where the pulse is picked up from the wrist is an artery.

동맥과 정맥을 방사선촬영으로 검사하는 혈관조영술은 1953년도에 완성되였는데, 조영제를 혈관속으로 주입한후 방사선촬영으로 동맥과 동맥으로부터 혈액을 공급받는 구조 모두를 관찰할 수 있지만, 조영제로 사용하는 요드화합물은 빈번히 심각한 부작용이 있다는 것이 지적되고 있는 실정이다.Angiography, in which the arteries and veins were examined by radiographs, was completed in 1953. After the injection of contrast medium into the blood vessels, both the arteries and the blood supply from the arteries can be observed. It is frequently pointed out that compounds have serious side effects.

통상 주사를 놓거나 수혈하고 채혈할 때는 정맥에서 이루어지나,심혈관 조영술을 위해 조영제를 투여하기 위해서는 팔의 동맥을 찾아 가는 플라스틱 카테터를 꽂아 어깨 가슴의 혈관을 따라 대동맥을 거쳐 심실로 가도록 한 후, 카테터를 통해 조영제를 주사하는 심혈관조영술을 실시할 경우에 팔의 동맥을 찾아야 하는데, 맥을 짚어 본 후 동맥을 구별했으나, 이러한 판단은 많은 숙련도를 요하기 것으로 경험이 부족한 경우에는 동맥을 찾는데 많은 애로가 많았지만 이렇다 할 의료기가 없는 실정이다.It is usually done in the vein when an injection is taken, or transfused and collected, but for cardiovascular angiography, a plastic catheter is placed in the artery of the arm, through the aorta along the blood vessel in the shoulder chest, and then the catheter. When performing cardiovascular angiography, the arteries of the arm should be searched for, and the arteries were distinguished after looking at the vein. However, this judgment requires a lot of skill. There is no medical device to do this.

본 발명에서는 동맥과 정맥 식별이 용이한 주사바늘구조를 제공하기 위한 것으로, 첨부(1b)와 단부(1c)로 이루어진 통상의 바늘(1)에 있어서, 상기 단부(1c) 에 일정 이격된 부위에 세공(1a)을 형성하며, 일측은 원추부(2a)를 이루며, 이측은 원통체인 몸통부(2b)가 일체로 이루어진 투명플라스틱제 허브(2)내에 상기 바늘(1)의 세공(1a)이 형성된 부위를 원추부(2a)에 위치시켜 고정시키되, 몸통부(2b)의 중공부에 위치된 바늘 단부에는, 몸통부 내부에서 원활히 왕복되는 피스톤(5)을 내재시킨후, 피스톤 후단에는 용수철(4)을 일체로 부착시킨 상태로 바늘의 단부(1c)는 상기 몸통부(2b) 중공부에 내재되는 원통의 외단에 외단턱이 형성된 허브캡(3)을 내재시킴과 동시에 허브캡 중앙부를 관통고정시켜 일체 밀봉 조립함을 특징으로 하는 주사바늘구조를 제공하게 된 것이다.In the present invention, to provide a needle structure for easy identification of arteries and veins, in the conventional needle (1) consisting of the attachment (1b) and the end (1c), at a portion spaced apart from the end (1c) The pores 1a of the needle 1 are formed in the transparent plastic hub 2 in which the pores 1a are formed, one side of which forms a cone portion 2a, and the other side of which is a cylindrical body portion 2b. The formed portion is positioned and fixed to the cone portion 2a, and the needle end located in the hollow portion of the trunk portion 2b has a piston 5 smoothly reciprocated inside the trunk portion, and then a spring ( 4) The end 1c of the needle with the body attached integrally embeds the hub cap 3 having the outer jaw formed at the outer end of the cylinder in the hollow part of the body portion 2b and penetrates the hub cap center part at the same time. Fixing to provide a needle structure, characterized in that the integral sealing assembly A.

본 발명에 따르면, 동맥과 정맥을 식별함에 있어서,그동안 맥진이나 경험측에 의존하여 동맥혈을 찾아 주사 바늘을 꼽았지만, 본 발명에 따르면 동맥이 정맥에 비해 혈압이 높다는 것을 감안해 용수철에 탄설된 정지상태의 피스톤이 후방으로 맥동되는 것을 투명한 허브를 통하여 쉽게 견지함으로써, 동맥주사 혈 자리인지 아닌지를 쉽게 식별할 수 있도록 한 것이다.According to the present invention, in the identification of arteries and veins, while the arterial blood is searched for the arterial blood depending on the pulsation or experience, the needle is inserted in the spring in consideration of the fact that the artery has a higher blood pressure than the vein. By easily holding the piston of the pulsating rear through the transparent hub, it is easy to identify whether the arterial injection site.

상기와 같은 문제를 해결하기 위하여, 본 발명에서는 이하 첨부된 도면에 의하여 본 발명의 일실시 구성을 알아보면 다음과 같다.In order to solve the above problems, the present invention will be described below with reference to one embodiment of the present invention by the accompanying drawings.

도 1 은 본 발명의 사시도,도 2 는 본 발명의 사용상태 단면도로 (ⅰ)은 동맥혈 주사전 피스톤이 정지된 상태의 참고도 (ⅱ)는 동맥혈 주사후 피스톤이 후퇴하는 것을 도시한 참고도로, Figure 1 is a perspective view of the present invention, Figure 2 is a cross-sectional view of the use state of the present invention (i) is a reference diagram of the piston stopped before arterial blood injection (ii) is a reference diagram showing that the piston retreats after arterial blood injection,

첨부(1b)와 단부(1c)로 이루어진 통상의 바늘(1)에 있어서, 상기 단부(1c) 에 일정 이격된 부위에 세공(1a)을 형성하며, 일측은 원추부(2a)를 이루며, 이측은 원통체인 몸통부(2b)가 일체로 이루어진 투명플라스틱제 허브(2)내에 상기 바늘(1)의 세공(1a)이 형성된 부위를 원추부(2a)에 위치시켜 고정시키되, 몸통부(2b)의 중공부에 위치된 바늘 단부에는, 몸통부 내부에서 원활히 왕복되는 피스톤(5)을 내재시킨후, 피스톤 후단에는 용수철(4)을 일체로 부착시킨 상태로 바늘의 단부(1c)는 상기 몸통부(2b) 중공부에 내재되는 원통의 외단에 외단턱이 형성된 허브캡(3)을 내재시킴과 동시에 허브캡 중앙부를 관통고정시켜 일체 밀봉 조립되어진 것이다.In the conventional needle 1 consisting of an attachment 1b and an end 1c, a fine hole 1a is formed at a predetermined distance from the end 1c, and one side forms a conical portion 2a, and a back side. In the transparent plastic hub (2) consisting of the body portion (2b) of the cylindrical body is formed by fixing the position where the pores (1a) of the needle (1) is formed in the cone (2a), the body portion (2b) In the needle end located in the hollow portion of the body, the piston 5 is smoothly reciprocated in the inside of the body portion, and then the end portion 1c of the needle is attached to the body portion with the spring 4 integrally attached to the rear end of the piston. (2b) It is integrally sealed and assembled by embedding the hub cap (3) having the outer jaw formed on the outer end of the cylinder in the hollow portion and at the same time through the hub cap center.

상기와 같이 구성된 본 발명의 일실시 작용을 알아보면, 첨부 도면 2에 도시된 바와 같이, 도 2 (ⅰ)은 상시에는 피스톤(5)이 용수철에 탄설된체 바늘의 세공부 후단에 정지된 상태를 보이나, 도 2의 (ⅱ)에서와 같이, 본 발명에 따른 주사바늘로 동맥혈자리를 찾아 주사하게 되면, 심장의 박동압에 의하여, 바늘의 첨부를 통해 유입된 혈류는 단부를 통해 유출되기도 하지만, 일부의 혈류는 허브 원추부위에 형성된 바늘의 세공을 통해 혈류가 유입되는 것이다.Referring to one embodiment of the present invention configured as described above, as shown in Figure 2, Figure 2 (i) is a state in which the piston (5) is always stopped at the rear end of the pore portion of the body needle coalesced in the spring However, as shown in (ii) of FIG. 2, when the artery acupuncture point is injected with an injection needle according to the present invention, due to the pulsating pressure of the heart, the blood flow introduced through the attachment of the needle may be discharged through the end. , Part of the blood flow is through the pores of the needle formed in the hub cone is blood flow is introduced.

만약, 동맥혈을 잘찾아 주사바늘을 꼽았다면, 혈압이 높은 혈류에 의하여, 당초 정지상태의 피스톤이 용수철의 탄발에도 불구하고 후방으로 맥동되는 현상을 보게 될 때 동맥혈을 제대로 찾은 경우이며, 만약 정맥혈에 주사바늘을 잘못 꼽았다면, 혈압이 낮아 용수철의 탄발에 의하여, 피스톤이 미동하지 않게 됨을 중공부에 내재된 피스톤의 상태를 투명한 허브를 통하여 견지함에 따라 동백과 정맥을 용이하게 식별할 수 있도록 한 것이다.If you find the arterial blood well and insert the needle, if you find the arterial blood properly when you see the piston pulsating backwards despite the spring of the spring due to the high blood pressure, If you insert the needle incorrectly, you can easily identify the camellia and vein by maintaining the state of the piston in the hollow part through the transparent hub that the piston is not moved due to the spring pressure. .

따라서, 본 발명에 채택되는 용수철의 응력은 동맥의 혈압에서만 반응을 나타내는 한도내의 용수철을 채택함이 바람직하다.Therefore, it is preferable to adopt a spring within the limit in which the spring stress employed in the present invention responds only to the arterial blood pressure.

참고로, 본 발명에 따른 피스톤의 색상은 붉은색을 제외한 것이 피스톤의 미동을 감지하는데 보다 효과적이다.For reference, the color of the piston according to the present invention is more effective in detecting the fine movement of the piston except red.

또한, 본 발명에 따른 허브와 허브캡 결합은 고주파웰딩방식으로 밀봉조립됨이 바람직하다. In addition, the hub and the hub cap coupling according to the present invention is preferably assembled in a high frequency welding method.
