Description

란셋용 천자바늘{Puncture needle for lancet}Puncture needle for lancet

본 발명은 란셋용 천자바늘에 관한 것으로, 보다 상세하게는 피부조직에 순간적으로 자입되어 체액, 특히 혈액을 채취하기 위한 란셋용 천자바늘에 관한 것이다.The present invention relates to a lancet puncture needle, and more particularly, to a lancet puncture needle for instantaneous incorporation into skin tissue to collect body fluids, particularly blood.

일반적으로 란셋은 건강진단이나 치료를 위해서 체액을 채취하거나 한방에서 수지침 및 부항 요법을 위해 사혈 할때 방혈장치에 장착되어 사용되는 소모품으로서, 란셋 일단에 돌출된 천자바늘이 피부조직에 직접적으로 자입되므로 통증이 동반될 수 밖에 없는 구조를 가진다.Generally, lancet is a consumable that is used in blood bleeding devices when collecting fluid for medical examination or treatment, or bleeding for acupuncture and cupping in one shot. It has a structure that can only be accompanied by pain.

예컨대, 부항요법을 위해 사혈용으로 란셋을 적용시 신체의 특정부분을 수십회에서 수백회에 걸쳐 연속 타침해야 하므로, 이때 환자가 느끼는 고통이 심각한 수준에 도달함은 물론 사혈부위의 피부조직이 손상되어 자연치유가 지연되는 문제점이 따랐다.For example, when applying lancet for blood injection for cupping therapy, it is necessary to finish the specific part of the body several times to hundreds of times, so that the pain felt by the patient reaches a serious level and the skin tissue of the blood-blooded area The problem was that natural healing was delayed due to damage.

이에 종래에 개시된 란셋용 천자바늘을 살펴보면, 특허공개번호 제10-2009-21343호에서 원통형상 부재로 형성되는 천자바늘은 단부에 형성되는 타원 후방부분, 타원 후방부분이 펼쳐지는 방향보다 더욱 비스듬히 아래쪽을 향하여 뻗어 있는 이등변 삼각형 부분, 이등변삼각형의 빗변으로부터 비스듬히 아래쪽을 향하여 뻗어 있는 우측경사면 부분 및 좌측경사면 부분, 원통형상 부재의 측면 일부분으로 구성되어 천자시에 느끼는 통증을 보다 줄이도록 하고 있다.Looking at the needle needle for the lancet disclosed in the prior art, in the patent publication No. 10-2009-21343 the puncture needle formed of a cylindrical member is more obliquely downward than the direction in which the ellipse rear portion, the ellipse rear portion is formed at the end It consists of an isosceles triangle part extending toward the side, a right inclined plane part and a left inclined plane part extending obliquely downward from the hypotenuse of the isosceles triangle, and a side part of the cylindrical member to reduce the pain felt during puncture.

그런데, 상기 종래기술은 천자시 통증을 경감시키기 위한 기술이지만, 천자바늘이 자입시 피부조직의 심각한 손상과 함께 통증완화 효과를 기대할 수 없는 실정이다.By the way, the prior art is a technique for reducing pain during puncture, but the situation where the puncture needle can not expect a pain relief effect with serious damage to the skin tissue.

즉, 타원 후방부분 및 이등변 삼각형 부분, 좌우측경사면 부분이 서로 만나는 각각의 변들이 천자바늘의 길이방향으로 날카로운 칼날을 형성함에 따라 천자바늘이 자입시 도 5에 도시된 바와 같이 피부조직이 "ㅅ"의 단면형상으로 절개된다.That is, the skin tissue is "s" when the puncture needle is inserted as the sides of the ellipse posterior part, the isosceles triangle part, and the left and right inclined plane parts each form a sharp blade in the longitudinal direction of the puncture needle. It is cut into the cross-sectional shape of.

이처럼 천자바늘에 형성되는 각각의 변에 의해 피부조직이 3개소로 절개됨에 따라 환자는 피부조직이 찢어지는 고통을 호소하고, 또 절개된 피부조직이 탄력을 상실하고 서로 벌어져 자연치유에 따른 회복속도가 지연됨과 더불어 자입부분이 흉터로 남게 되는 폐단이 따랐다.As the skin tissue is cut into three places by each stool formed on the puncture needle, the patient complains of the pain of tearing the skin tissue, and the cut skin tissue loses its elasticity and opens up with each other, thereby recovering from natural healing. In addition to the delay, the indentation was left with scarring.

본 발명은 상기한 문제점을 해결하기 위해 착안 된 것으로서, 천자시 통증을 완화하고, 천자후 흉터가 남지 않고 자연치유에 따른 회복속도를 단축시키기 위한 란셋용 천자바늘에 관한 것이다.The present invention has been conceived to solve the above problems, and relates to a lancet puncture needle for relieving pain during puncture, and to shorten the recovery rate due to natural healing without scarring after puncture.

이러한 목적을 달성하기 위해 본 발명의 특징은, 란셋몸체(1)상에 구비되고, 침체(10) 및 침날(20), 침첨(30)으로 구성되는 란셋용 천자바늘에 있어서, 상기 침날(20)은 침체(10)와 침첨(30)사이에 형성되고, 침체(10)의 외주면에 각 점과 침첨(30)을 이은 선분(22) 전체가 원뿔형상으로 형성되는 것을 특징으로 한다.In order to achieve the above object, a feature of the present invention is provided on the lancet body (1), in the needle needle for lancet consisting of the needle 10 and needle 20, the needle needle 30, the needle blade 20 ) Is formed between the recession 10 and the acupuncture 30, the entire line segment 22 connecting each point and the acupuncture 30 on the outer circumferential surface of the recess 10 is formed in a conical shape.

이때, 상기 침날(20)을 형성하는 선분(22)은 직선 또는 포물선으로 형성되는 것을 특징으로 한다.At this time, the line segment 22 forming the needle 20 is characterized in that formed in a straight line or parabola.

또한, 상기 침날(20)을 형성하는 선분(22)은 15~35도의 경사각으로 형성되는 것을 특징으로 한다.In addition, the line segment 22 forming the needle blade 20 is characterized in that formed at an inclination angle of 15 to 35 degrees.

또한, 상기 침첨(30)은 꼭지점이 곡률가공되어 형성되는 것을 특징으로 한다.In addition, the acupuncture 30 is characterized in that the vertex is formed by the curvature processing.

이상의 구성 및 작용에 의하면, 침날이 원뿔형으로 형성되어 천자시 피부조직이 절개되지 않고 확장 팽창됨에 따라 통증이 환화됨은 물론 천자후 확장 팽창된 피부조직이 자연스럽게 수축되어 자연치유에 따른 회복시간이 단축되고, 또 피부조직의 손상 및 변형으로 인한 흉터발생이 방지되는 효과가 있다.According to the above configuration and action, the needle blade is formed in a conical shape, the pain is circulated as the skin tissue is expanded and not expanded during puncture, and the expanded and expanded skin tissue is naturally contracted after the puncture, and the recovery time due to natural healing is shortened. In addition, there is an effect to prevent scarring caused by damage and deformation of the skin tissue.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 란셋용 천자바늘에 관련되며, 이때 란셋용 천자바늘은 란셋몸체(1)상에 구비되고, 침체(10) 및 침날(20), 침첨(30)으로 구성되어 천자시 통증을 완화하고, 천자후 흉터가 남지 않고 자연치유에 따른 회복속도를 단축시키기 위해 침날(20)이 원뿔형상으로 이루어진다.The present invention relates to a lancet puncture needle, wherein the lancet puncture needle is provided on the lancet body (1), consisting of the stagnation 10 and the needle blade 20, acupuncture (30) to relieve pain during puncture , After the puncture scars do not remain and the needle blade 20 is made in the shape of a cone in order to shorten the recovery rate due to natural healing.

본 발명에 따른 침날(20)은 침체(10)와 침첨(30)사이에 형성되고, 침체(10)의 외주면에 각 점과 침첨(30)을 이은 선분(22) 전체가 원뿔형상으로 형성된다. 침체(10)는 원기둥형상으로 형성되어 일단이 란셋본체상에 고정되고, 다른 일단에는 침날(20)과 침첨(30)이 형성된다.The needle blade 20 according to the present invention is formed between the needle recess 10 and the needle needle 30, the entire line segment 22 connecting each point and the needle needle 30 on the outer circumferential surface of the needle needle 10 is formed in a conical shape. . The recess 10 is formed in a cylindrical shape, one end of which is fixed on the lancet body, and the other end of the needle 10 and the needle tip 30 are formed.

이때, 침날(20)은 침체(10)와 침첨(30)을 이은 선분들로 이루어지는바, 즉 침체(10)의 외주면에 임의의 각 점들과 침첨(30)을 연결하는 선분(22)들에 의해 원뿔형상으로 형성된다.At this time, the needle blade 20 is composed of a line segment connecting the recession 10 and the acupuncture 30, that is, to the line segments 22 connecting arbitrary points and acupuncture 30 to the outer circumferential surface of the recession 10. By conical shape.

그리고, 상기 침날(20)을 형성하는 선분(22)은 직선 또는 포물선으로 형성된다. 도 2a 는 침날(20)의 선분(22)이 직선으로 형성된 상태를 도시하고, 도 2b는 선분(22)이 포물선으로 형성된 상태를 나타낸다.In addition, the line segment 22 forming the needle 20 is formed in a straight line or parabola. FIG. 2A shows a state in which the line segment 22 of the needle blade 20 is formed in a straight line, and FIG. 2B shows a state in which the line segment 22 is formed in a parabola.

또, 침날(20)을 형성하는 선분(22)은 15~30도의 경사각으로 형성된다. 선분(22)의 양단부가 이루는 각이 침체(10)의 길이방향을 축으로 15~35도 형성되되, 15도 이하의 각도로 형성되면 천자시 통증은 완화되나 채액 채취율이 저하되고, 35도 이상의 각도로 형성되면 채액 채취율은 향상되나 고통이 증가되므로, 바람직하게는 25도로 형성되는 것이 바람직하다. In addition, the line segment 22 forming the needle blade 20 is formed at an inclination angle of 15 to 30 degrees. Angles formed at both ends of the line segment 22 are formed at an angle of 15 to 35 degrees along the longitudinal direction of the recession 10, and when formed at an angle of 15 degrees or less, pain during puncture is relieved, but the sampling rate is lowered, and the angle is 35 degrees. When the angle is formed at the above angle, the liquid collection rate is improved, but the pain is increased, and preferably, it is preferably formed at 25 degrees.

또한, 상기 침첨(30)은 꼭지점이 곡률가공되어 형성되는바, 도 3에 도시된 바와 같이 침첨(30)부분의 꼭지점을 포물선의 평면좌표로 표시하였을때, 원점에서의 곡률이 10~37.5의 범위로 형성된다. 이때 침첨(30)의 꼭지점 곡률이 10이하의 곡률로 형성되면 내구성이 저하되어 쉽게 마모되고, 37.5이상으로 형성되면 침첨(30)이 무뎌져 천자효율이 저하되는 문제점이 따르므로, 바람직하게는 25의 곡률로 형성되는 것이 바람직하다.In addition, the acupuncture 30 is formed by the process of curvature of the vertex bar, as shown in Figure 3 when the vertex of the portion of the acupuncture 30 is represented by the plane coordinates of the parabola, the curvature at the origin of 10 ~ 37.5 Formed into a range. At this time, if the vertex curvature of the acupuncture 30 is formed to a curvature of 10 or less, the durability is easily degraded and worn, and when formed at 37.5 or more, the attenuation 30 is blunted and the puncture efficiency is lowered. It is preferable that it is formed with the curvature of.

이처럼, 침날(20)이 원뿔형으로 형성되어 천자시 피부조직이 절개되지 않고 도 4처럼 확장 팽창됨에 따라 자입통증이 환화됨은 물론 천자후 확장 팽창된 피부조직이 자연스럽게 수축되어 자연치유에 따른 회복시간이 단축되고, 또 피부조직의 손상 및 변형으로 인한 흉터발생이 방지된다.In this way, the needle blade 20 is formed in a conical shape, as the skin tissue is not incised at the time of puncture and expanded and expanded as shown in FIG. It is shortened and scarring due to damage and deformation of skin tissue is prevented.

뿐만 아니라, 침첨(30)이 곡률가공됨에 따라 수십회에서 수백회를 연속적으로 천자시 마모로 인한 수명단축이 방지됨과 더불어 천자시 통증이 완화되는 이점이 있다.In addition, as the acupuncture 30 is curvature-processed, there is an advantage that the lifespan is prevented due to abrasion during tens to hundreds of successive punctures, and the pain is relieved.
