본 발명은 혈침관에 관한 것이다.The present invention relates to blood vessels.
종래의 혈침관은 양단부가 개구되고, 길이 30mm, 내경 3mm의 유리관에 의하여 만들어져 있다. 이 유리관의 일단부의 개구에서부터 20cm에 걸쳐 1mm 눈금이 표시되어 있다. 그리고, 이와 같은 종래의 혈침관을 사용해서 혈침검사를 행하나, 이 혈침검사는 다음과 같이 해서 행하여 진다. 먼저, 혈액에 혈액응고체, 예를 들면, 3,8% 구연산나트륨을 첨가하고, 사람이 빨아들이므로서 혈침관내를 감압해서, 혈액을 혈침관의 0점(기점)까지 넣고, 또는 주사기등으로 혈액을 혈침관의 0점까지 넣고 있었다. 다음에, 이 혈침관을 수직으로 움직이지 않게 놓고, 시간마다 적혈구의 침강된 계면(界面)을 측정한다. 그리고, 혈침검사의 종류후에는, 사용한 혈침관을 세정, 멸균, 건조등을 행하여, 혈침관을 재생사용하고 있다.The conventional blood needle tube is open at both ends and is made of a glass tube having a length of 30 mm and an inner diameter of 3 mm. A 1 mm scale is indicated over 20 cm from the opening of one end of this glass tube. Then, a blood acupuncture test is performed using such a conventional blood acupuncture tube, and this blood acupuncture test is performed as follows. First, a blood coagulant, for example, 3,8% sodium citrate, is added to the blood, and a person sucks in to depressurize the inside of the hemorrhage and put the blood to the zero point of the hemorrhage, or a syringe or the like. The blood was put to the 0 point of the blood vessel. Next, the blood needle tube is not moved vertically, and the settled interface of red blood cells is measured every time. After the type of blood needle test, the used blood needle tube is washed, sterilized and dried to regenerate the blood needle tube.
그러나, 상기의 혈침관을 사용하여 혈침검사를 행하기 위해서는, 먼저, 사람이 입으로 빨거나, 주사기를 사용하여 혈침관의 0점까지 혈액을 넣을 필요가 있다. 이 조작은, 단순하지만, 숙영을 요하는 것이고, 또한, 이와 같이 수작업은 시간이 걸리며, 다수검체를 단시간으로 처리하는 것은 곤란하다. 또, 상기와 같은 작업과정, 또는, 재생사용에 의한 세정, 멸균, 건조등의 작업과정에 있어서, 의료종사자가 혈액으로부터 유래되는 질병, 예를 들면, 비루스성간염, AIDS등의 원내감염의 가능성이 있으며, 또한 재생사용에 수반하는 작업도 시간이 걸린다. 또 상기 혈침관을 장기간에 걸쳐서 사용하고 있으며, 벽면에 지방, 단백질등이 부착하여, 세정이 불완전하게 되기 쉽고, 얻어진 데이터가 불완전하게 되는 우려가 있다.However, in order to perform a blood acupuncture test using the above-described blood needle, it is first necessary for a person to suck into his mouth or to inject blood to the zero point of the blood needle through a syringe. Although this operation is simple, it requires a camping, and the manual work takes time in this way, and it is difficult to process a large number of samples in a short time. Furthermore, in the above work process or during work such as cleaning, sterilization and drying by regeneration, the possibility of medical infections in the hospital such as viral hepatitis, AIDS, etc. In addition, the work associated with the use of regeneration also takes time. In addition, the blood vessels have been used for a long time, and fats, proteins, and the like adhere to walls, which may result in incomplete cleaning and incomplete data.
그래서, 본 발명은, 상기 사정을 감안하여 이루어진 것으로서, 조작이 용이하고 시간이 걸리지 않으며, 의료종사자가 혈액으로부터 유래되는 질병에 감염되는 일없이, 또한, 얻어진 데이터의 신뢰성이 높은 혈침관을 얻는 것을 목적으로 한다.Therefore, the present invention has been made in view of the above circumstances, and it is easy to operate, it does not take time, and a medical practitioner can obtain a highly reliable blood acupuncture tube without being infected with a disease derived from blood. The purpose.
상기 과제를 해결하기 위하여, 본 발명의 혈침관은 균일한 내경을 가지고 또한 양단가 개구되는 있는 합성수지관의 어느 것이든 한쪽의 개구를 테이퍼현상으로 형성하고, 이 테이퍼형상개구로부터 상기 합성수지 관내의 소정위치에, 기체는 통과하지만 액체는 통과시키지 않는 특성을 가진 다공성합성수지체를 끼위 불이고, 어느쪽이든 다른쪽의 개구를 액체유입구로하는 것이다. 또, 액체유입구쪽으로부터 합성 수지관에 눈금을 표시하고, 다공합성수체의 일단부면이 상기 눈금의 기점이 되도록, 상기 합성수지관내에 상기 다공합성수지체를 끼워 붙이면된다.In order to solve the above problems, the blood needle tube of the present invention has a taper phenomenon in which one of the synthetic resin tubes having a uniform inner diameter and open at both ends is tapered, and a predetermined position in the synthetic resin tube is formed from the tapered opening. For example, a porous synthetic resin having a property of passing gas but not liquid is fired, and either side of the opening is the liquid inlet. A scale may be displayed on the synthetic resin tube from the liquid inlet side, and the porous synthetic resin body may be inserted into the synthetic resin tube so that one end surface of the porous synthetic resin is a starting point of the scale.
상기 구성의 혈침관에 의하면, 합성수지관의 테이퍼현상개구로부터 합성수지관내의 소정위치에, 기체를 통과시키지만 액체를 통과시키지 않는 특성을 가진 다공성합성수지체를 끼워붙이고 있으므로, 다공성 합성수지체를 소정위치에 용이하게 장착할 수 있고, 테이퍼형상개구쪽으로부터 흡입하면, 혈액등의 액체는 소정위치에 장착된 다공성합성수지체의 일단부면까지 즉시 유입하고, 다공성합성수지체에 의해서 그 이상 유입하지 않는다. 이후, 혈침관을 수직으로해서 적혈구의 침강상태를 소정시간마다 측정한다.According to the blood immersion tube of the above constitution, a porous synthetic resin having a characteristic of passing gas but not allowing liquid to pass through the taper phenomenon opening of the synthetic resin tube is inserted in the synthetic resin tube, so that the porous synthetic resin can be easily placed at the predetermined position. When it is inhaled from the tapered opening, the liquid such as blood immediately flows to one end surface of the porous synthetic resin mounted at a predetermined position and no more flows through the porous synthetic resin. Thereafter, the settling state of the red blood cells is measured every predetermined time with the blood needle tube vertically.
또, 유체유입구쪽으로부터 눈금을 기입, 이 눈금의 기점이 되는 위치에 다공성합성수지체의 일단부면이 위치하도록 한 것으로서, 테이퍼형상 개구쪽으로부터 흡인하면 혈액등의 액체는 눈금의 기점까지 즉시 유입하고, 다공성합성수지체에 의해서 그 이상 유입하지 않는다.In addition, one end surface of the porous synthetic resin body is positioned at the starting point of the graduation, and when drawn from the tapered opening, liquid such as blood flows immediately to the starting point of the graduation. No more inflow by the porous synthetic resin.
이하, 본 발명의 실시예를 첨부도면에 의거하여 상세하게 설명한다. 도면은 본 발명의 혈침관의 사시도이다. 동도면에 있어서, (1)은 혈침관을 표시하고, 이 혈침관(1)은, 예를 들면, 폴리에칠린, 폴리스티린, 폴리프로필렌등의 합성수지관(2)으로부터 만들어지고 있다. 이 합성수지관(2)은 내경이 균일하게 형성되고 또한 양단부가 개구되어 있다. 이 합성수지관(2)의 일단부는, 혈액등의 액체를 유입시키는 액체유입구(3)로 되어 있다. 이 합성수지관(2)의 타단부는 테이퍼형상으로 형성되고, 이 테이퍼형상개구(4)는, 합성수지관(2)내의 소정위치에 다공성합성수체(5)를 끼워붙이기 쉽도록 형성된 것이다. 이 다공성합성수지체(5)는, 기체는 통과하지만, 액체는 통과시키지 않는 특성을 가지고 있다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The figure is a perspective view of the blood needle tube of the present invention. In the same figure, reference numeral 1 denotes a blood needle tube, and the blood needle tube 1 is made from a
이 다공성합성수지체(5)는, 폴리에틸렌, 폴리프로필렌, 에틸렌, 아세트산비닐공중합체, 폴리스틸렌, 아크릴로니트릴계 공중합체등의 열가소성수지의 분입체를 반응성형을 해서 얻어진 다공질체내에 고흡수성고분자(건조겔)을 밀착시키므로서 얻어지는 것이다.The porous synthetic resin (5) is a superabsorbent polymer (dried) in a porous body obtained by reacting an aliquot of a thermoplastic resin such as polyethylene, polypropylene, ethylene, vinyl acetate copolymer, polystyrene and acrylonitrile copolymer. It is obtained by making gel) adhere.
여기서, 반응성형이란, 상기와 같은 열가소성수지의 분입체를 일정형상의 금형에 충전하고, 기공율을 조정할 목적으로 충전충을 가압하고, 또, 이 분입체충전층을 균일하게 가열해서, 입자의 접촉표면이 반응상태로 융착된 시점에서 냉각해서, 각 입자간 빈틈이 완전히 연속된 3차원적공간(기공)을 형성시키는 성형법을 말한다. 또, 고흡수성분자란, 젤라틴, 한천, 아리비아고무등의 흡수능 및 봉지능력이 있는 고분자화합물을 말하며, 건조겔이란, 이 고흡수성 고분자가 건조된 상태의 것을 말한다.Here, the reactive type is filled with the above-mentioned thermoplastic resin injector into a mold of a certain shape, pressurized the filling filler for the purpose of adjusting the porosity, and uniformly heating the injector filled layer to contact the particles. It refers to a molding method in which a surface is fused at a reaction state and cooled to form a three-dimensional space (pores) in which gaps between particles are completely continuous. In addition, a super absorbent component means the high molecular compound which has absorption ability and encapsulation ability, such as gelatin, agar, an aribian rubber, and a dry gel means that this superabsorbent polymer is in the dried state.
따라서, 상기 다공성합성수지체(5)는, 상기 열가소성수지의 분입체를 반응성형해서 얻어진 다공질체내에 건조겔 상태의 고흡수성고분자를 밀착시킨 것이므로, 공기둥의 기체를 통과시키나, 혈액등의 액체가 다공성합성수지체(5)에 접촉하면, 건조겔 상태의 고흡수성 고분자가 액체를 순간적으로 흡수해서, 건조겔 형상의 고흡수성고분자가 팽윤하고, 액체를 통과시키지 않게 된다.Therefore, the porous synthetic resin body 5 adheres the superabsorbent polymer in the dry gel state to the porous body obtained by reactively injecting the thermoplastic resin particle, so that a gas such as blood is allowed to pass through the air. In contact with the porous synthetic resin 5, the super absorbent polymer in the dry gel state absorbs the liquid instantaneously, and the dry gel superabsorbent polymer swells and does not pass through the liquid.
이 다공성합성수지체(5)는, 그 일단부면(5a)가 액체유입구(3)쪽으로부터 1mm 새김으로 눈금을 표시하고, 20cm의 곳이 0점(기점)으로 위치하도록 합성수지관(2)내에 끼워 부쳐져 있다.The porous synthetic resin body 5 is marked with a 1 mm mark from one
다음에, 상기 구성으로 이루어진 혈침관의 사용방법을 성명한다.Next, a method of using the blood immersion tube having the above configuration will be described.
먼저, 본 발명의 혈침관(1)을 준비하고, 구연산나트륨에 의해서 응고방지된 혈액이 들어있는 시험관등의 속에, 혈침관(1)의 액체유입구(3)을 넣는다. 다음에, 펌프등으로 테이퍼형상개구(4)쪽으로부터 합성수지관(2)내를 감압하면, 액체유입구(3)로부터 합성수지관(2)내에 혈액이 들어가고, 이 혈액이 눈금이 0점, 즉 다공성합성수지체(5)의 일단부면(5a)에 도달하면, 다공성합성수지체(5)내에 밀착된 건조겔상태의 고흡수성고분자가 순가적으로 혈액속의 수분을 흡수하여 팽윤해서 봉지 상태로 되어, 혈액은 0점에서 정지한다.First, the blood needle tube 1 of the present invention is prepared, and the
따라서, 혈침관(1)내에 혈액을 0점까지 넣는 조작은, 용이하고도 순간적으로 행할 수 있다. 이루, 혈침관(1)을 수직으로해서, 적혈구의 침강상태를 소정시간마다 측정하면 된다. 측정후, 상용된 혈침관(1)은 폐기한다.Therefore, the operation of putting the blood to the zero point in the blood needle tube 1 can be performed easily and momentarily. Then, the blood needle tube 1 is made vertical, and the settling state of the red blood cells may be measured every predetermined time. After the measurement, the used blood needle tube 1 is discarded.
이상 상세히 설명한 바와 같이, 본 발명의 혈침관은 균일한 내경을 가지며 또한 양단부가 개구되어 있는 합성수지관의 어느한쪽의 개구를 테이퍼현상으로 성형하고, 이 테이퍼형상개구로부터 상기합성수지관내의 소정위치에, 기체는 통과하나 액체는 통과시키지 않는 특성을 가진 다공성합성수지체를 끼워붙이고, 어느쪽이든지 다른쪽의 개루를 액체유입구로 하였으므로, 값싼 합성수지로 제작할 수 있고, 또한, 테이퍼형상개구로부터 다공성합성수지체를 송정위치에 끼워붙이므로 제작이 용이하게 되어, 혈침관을 값싸게 제작할 수 있다. 이 때문에, 사용후 폐기가 가능해지고, 종래와 같이 재생사용을 위한 세정, 멸균, 건조등의 작업이 없어진다. 또 세정이 불완전하기 때문에 벽면에 부착된 지방, 단백질에 의해서, 얻어진 테이터의 신뢰성의 저하도 없어진다. 또한, 이와 같은 작업과정이 없으므로, 혈액으로부터 유래되는 비루스성간염, AIDS등의 질병에 감염되는 우려가 거의 없다. 또, 테이퍼 형상개구쪽으로부터 흡입하면 혈액등의 액체는, 소정위치에 끼워 붙인 다공성합성수지체의 일단부면에 즉시 유입해서, 그 이상 유입하지 않으므로 조작이 용이하고 작업시간도 얼마 안되어, 인건비도 감소시킬 수 있다. 또, 상기의 작업과정에서는 혈액에 접촉되는 기회가 거의 없으므로, 혈액으로부터 유래되는 상기 질병도 거의 없다.As described in detail above, the blood needle tube of the present invention has a uniform inner diameter and is formed by tapering the opening of one of the synthetic resin tubes having both ends opened, and from this tapered opening, at a predetermined position in the synthetic resin tube, A porous synthetic resin having characteristics of passing gas but not liquid is inserted, and either side of the other opening is used as a liquid inlet, so that the synthetic resin can be made of cheap synthetic resin and the porous synthetic resin is transferred from the tapered opening. Since it fits in the position, it becomes easy to manufacture and it can manufacture a blood needle tube cheaply. For this reason, disposal after use becomes possible, and operation | movement such as washing | cleaning, sterilization, and drying for a regeneration use is eliminated like conventionally. In addition, since the washing is incomplete, a decrease in the reliability of the obtained data is eliminated by fats and proteins attached to the wall surface. In addition, since there is no such work process, there is little fear of being infected with diseases such as viral hepatitis and AIDS derived from blood. In addition, when inhaled from the tapered opening, liquid such as blood immediately flows into one end surface of the porous synthetic resin stuck to a predetermined position, and since it does not flow any more, it is easy to operate and the working time is shortened, thereby reducing labor costs. Can be. In addition, there is almost no chance of contact with blood in the above working procedure, and therefore, there is almost no such disease derived from blood.
또, 액체유입구쪽으로부터 합성수지관에 눈금을 표시하고, 다공성 합성수지체의 일단부면이 상기 눈금의 기점이 되도록, 상기 합성수지관내에 상기 다공성합성수지체를 끼워붙이고 있으므로, 테이퍼형상개구쪽으로부터 흡인하면, 혈액등의 액체는 합성수지관내에 눈금의 기점까지 즉시 유입한다. 따라서, 눈금의 기점까지 핼액등의 액체를 유입시키는데 조절을 할 필요가 없으므로, 혈침검사의 준비작업이 용이하다.In addition, since the scale is marked on the synthetic resin tube from the liquid inlet side and the one end surface of the porous synthetic resin is inserted into the synthetic resin tube so that the one end surface of the porous synthetic resin body is attracted from the tapered opening, The back liquid immediately flows into the synthetic resin pipe up to the starting point of the graduation. Therefore, it is not necessary to adjust the flow of liquids such as heal solution to the starting point of the scale, so that preparation work for blood needle test is easy.
