Description

초음파를 이용한 중심정맥관 삽입술에 사용되는 개량된 정맥 천자 주사바늘 및 확장관{Improved venous puncture needle and expansion tube for ultrasound-assisted central venous insertion}Improved venous puncture needle and expansion tube for ultrasound-assisted central venous insertion

본 발명은 초음파를 이용하여 중심정맥관 삽입 시술시 사용하는 개량된 정맥 천자 주사바늘 및 확장관에 관한 것으로서, 더욱 상세하게는 초음파를 이용하여 혈관 천자시 천자 바늘 끝을 short bevel로 하여 조직손상을 최소화 하고, 천자 바늘이 초음파상에서 잘 보이도록 처치를 하며, 환자의 피부로부터 정맥 천자 주사바늘의 삽입되는 깊이를 파악하기위해 바늘외면에 눈금이 표시되고, 확장관의 외면에도 상기 눈금과 동일한 눈금이 표시되어 정맥 천자 주사바늘과 동일한 깊이로 확장관이 삽입되는 것을 특징으로 하는 초음파를 이용한 중심정맥관 삽입술에 사용되는 개량된 정맥 천자 주사바늘 및 확장관에 관한 것이다.The present invention relates to an improved venous puncture needle and dilatation tube used for insertion of a central venous tube using ultrasound, and more particularly, minimizing tissue damage by making the tip of the puncture needle short bevel when puncturing blood vessels using ultrasound. The puncture needle is treated so that it is clearly visible on the ultrasound, and a scale is displayed on the outer surface of the needle to determine the depth of the venous puncture needle inserted from the patient's skin, and the same scale as the scale is displayed on the outer surface of the dilatation tube. The present invention relates to an improved venous puncture needle and dilatation tube used for central venous cannulation using ultrasound, characterized in that the dilatation tube is inserted at the same depth as the venous puncture needle.

중심정맥삽관이란 목 부위의 내경정맥 또는 어깨부위의 쇄골하정맥등을 통해 심장으로 연결되는 대정맥에 주사용 도관을 삽입하는 시술로 쇼크나 대량 출혈 등 다량의 수액공급이나 수혈이 필요한 경우 말초정맥보다 더 효과적으로 수액이나 혈액을 주입하기위해 실시되는 것이다. 또한, 고농도 영양제나 일부 항암제를 투여할 때도 실시되는데 고농도 영양제와 일부 항암제는 말초정맥을 통하여 주사할 경우 혈관손상을 유발시킬 수 있고, 말초정맥에 삽입된 도관의 경우 3일 이상 사용할 수 없으므로 장기간의 약물치료가 필요할 경우 중심정맥삽관을 통하여 약물치료를 실시한다. 그 외로는 쇼크에 빠진 환자의 중심정맥의 압력을 측정하거나 혈액투석을 시행할 때 실시된다.Central venous intubation is a procedure in which a conduit for injection is inserted into the vena cava that is connected to the heart through the internal jugular vein in the neck or the subclavian vein in the shoulder area. It is done to inject fluids or blood more effectively. In addition, it is also carried out when high-concentration nutrients or some anticancer drugs are administered.If injected through the peripheral vein, high-concentration nutrients and some anticancer drugs can cause damage to blood vessels, and a catheter inserted into the peripheral vein cannot be used for more than 3 days. If drug treatment is needed, drug treatment is performed through central venous intubation. Others are used when measuring the pressure in the central vein of a patient in shock or performing hemodialysis.

시술방법은 쇄골하정맥이나 내경정맥등을 주로 이용하는데 일반적으로는 의료진의 해부학적 지표를 통해 삽관을 시행하고 있지만 정확한 삽관을 위해 초음파나 방사선 영상으로 확인을 하면서 시술하고 있으며, 시술과정은 환자가 침대에 누운상태에서 자세를 잡고, 삽관할 부위의 피부를 소독한 후 멸균 구멍 포로 시술부위를 덮은 다음 시술시 통증을 줄이기 위해 국소 마취제를 주사한 다음 천자 주사바늘로 혈관을 천자하고, 혈관 내부로 가는 안내용 철선을 삽입한 다음 수술용 칼로 피부를 소정 절개한 후 확장관을 이용하여 조직을 넓혀준 뒤 도관을 삽입하여 피부에 도관을 고정시키고, 드래싱하는 순서로 이루어져 있다.The procedure mainly uses subclavian vein or internal jugular vein. In general, intubation is performed through the anatomical index of the medical staff, but the procedure is performed while confirming with ultrasound or radiographic images for accurate intubation. While lying on the bed, hold the posture, disinfect the skin of the site to be intubated, cover the treatment site with a sterile hole cap, inject a local anesthetic to reduce pain during the procedure, puncture the blood vessel with a puncture needle, and puncture the blood vessel inside the blood vessel. After inserting a thin guide wire, a predetermined incision is made to the skin with a surgical knife, and then the tissue is widened using an expansion tube, and a catheter is inserted to fix the conduit to the skin, followed by drashing.

한편, 시술과정에서 천자 주사바늘 및 확장관 삽입시 폐를 찌르면 기흉이 발생될 수 있고, 정맥의 일측면에 위치된 동맥을 찌르거나 혈관벽이 찢어져 출혈이 발생될 수 있으며, 출혈 양이 많을 경우에는 혈종을 형성하거나 내부에 혈액이 고일 수 있는 치명저인 합병증이 발생할 수 있으므로 천자 및 확장시 정확한 위치와 삽입 깊이를 측정하며 시술할 필요성이 높다.On the other hand, pneumothorax may occur if the lungs are pierced when inserting a puncture needle and dilatation tube during the procedure, and bleeding may occur due to piercing an artery located on one side of the vein or tearing the blood vessel wall. There is a high need to measure the exact location and depth of insertion during puncture and expansion as complications that may form hematomas or accumulate blood inside may occur.

Is displayed,

확장관의 외면에도 상기 눈금과 동일한 눈금이 표시되어 정맥 천자 주사바늘과 동일한 깊이로 확장관이 삽입된다.The same scale as the scale is displayed on the outer surface of the dilatation tube, and the dilatation tube is inserted at the same depth as the venous puncture needle.

일반적으로 주사바늘은 게이지(gauge, G)로 나누어지며, 이때 바늘 굵기를 “게이지”라고 칭하는데 통상적으로 정맥주사시 사용되는 주사바늘의 굵기는 18(1.20mm)~24(0.65mm)G를 사용되며, 주사 바늘의 재질은 스테인리스로 이루어진다.In general, injection needles are divided into gauges (G). At this time, the thickness of the needle is called “gauge”, and the thickness of the injection needle used for intravenous injection is 18(1.20mm)~24(0.65mm)G. It is used, and the material of the injection needle is made of stainless steel.

상기 혈관 천자 및 확장시 초음파는 정맥의 단면을 보여주는 쇼트 액시스(short axis)와 정맥의 측면 방향을 보여주는 롱 액시스(long axis)로 측정하며 정맥 주사 천자시 정확한 정맥 위치와 깊이를 측정하며 천자와 확장을 실시한다.The ultrasound during puncture and dilation of blood vessels is measured with a short axis showing the cross section of a vein and a long axis showing the lateral direction of the vein. Conduct.

눈금이 표시된 정맥 천자 주사바늘을 내경정맥이나 쇄골하정맥에 천자시 초음파장치를 롱 액시스(long axis)로 측정하면서 삽입되는 길이를 측정하는 것이 바람직하며, 확장관 삽입시에도 측정된 길이만큼 초음파장치를 롱 액시스(long axis)로 측정하면서 삽입하는 것이 바람직하다. When puncturing a marked venous puncture needle into the internal jugular vein or subclavian vein, it is desirable to measure the length of insertion while measuring the ultrasonic device with a long axis. It is preferable to insert while measuring with a long axis.

상기 정맥 천자 주사바늘 및 확장관에 표시되는 눈금은 인그레이빙(engraving) 방식을 적용하여 주사바늘 및 확장관 외면에 미세한 홈을 복수개 형성시킨다.The scales displayed on the venous puncture needle and the dilatation tube apply an engraving method to form a plurality of fine grooves on the outer surfaces of the injection needle and dilatation tube.

상기 정맥 천자 주사바늘은 스테인레스 재질로 이루어져 있고, 마이크로 인그레이빙을 적용하여 일정간격으로 미세한 홈을 구비하여 천자시 초음파를 이용하여 삽입 깊이를 측정할 수 있고, 확장관 외면에 상기 정맥 천자 주사바늘과 동일한 간격으로 인그레이빙을 이용한 홈 내지 눈금이 표시되어 정맥 천자 주사바늘의 삽입 길이만큼 삽입 시킬 수 있다. 한편, 상기 확장관의 경우 합성수지재로 이루어져 인그레이빙을 이용하여 눈금을 표시하나 도료를 이용하여 외면에 눈금을 표시하여도 무방하다.The venous puncture needle is made of stainless material, and micro-engraving is applied to provide fine grooves at regular intervals to measure the insertion depth using ultrasound during puncture, and the venous puncture needle on the outer surface of the dilatation tube Grooves or scales using engraving are displayed at the same interval as and can be inserted as much as the length of the venous puncture needle. On the other hand, in the case of the expansion tube, it is made of a synthetic resin material to mark the scale using engraving, but it is also possible to mark the scale on the outer surface using paint.

상기 정맥 천자 주사바늘은 혈관 천자시 주사바늘의 경사면이 상방을 향한 상태로 삽입되고, 정맥 천자 주사바늘에 표시되는 눈금은 삽입되는 바늘의 상부면에 표시된다.The venous puncture needle is inserted in a state in which the inclined surface of the injection needle faces upward during vascular puncture, and the scale displayed on the venous puncture needle is displayed on the upper surface of the inserted needle.

정맥 천자 주사바늘에 표시되는 눈금은 주사바늘의 원둘레를 따라 전체 표시되거나 상방을 포함하는 양측면에 표시 되어 초음파에 상기 눈금의 식별이 잘 이루어질 수 있도록 하는 것이 바람직하다.It is preferable that the scale displayed on the venous puncture needle is displayed on both sides including the upper or the whole along the circumference of the needle so that the scale can be easily identified by ultrasound.

상기 정맥 천자 주사바늘은 삽입되는 방향의 끝단이 short-bevel로 이루어져 있다.The venous puncture needle has a short-bevel end in the direction of insertion.

일반적으로 사용되는 정맥 천자 주사바늘은 삽입되는 끝단이 long-bevel의 긴 경사각도를 가지는 주사 바늘을 사용하나 혈관 천자시 혈관 조직을 손상이 일어날 가능성이 있으므로 long-bevel에 상대적으로 경사각도가 저감된 short-bevel로 이루어진 정맥 천자 주사바늘을 사용하여 혈관 조직의 손상을 방지한다.In general, venous puncture needles use an injection needle with a long inclination angle of a long-bevel, but the inclination angle is relatively reduced to a long-bevel because there is a possibility of damage to the vascular tissue during vascular puncture. A venous puncture needle made of short-bevel is used to prevent damage to vascular tissue.

일반적으로 long-bevel의 주사바늘은 바늘끝의 경사도가 12°(±2°)이고, 본 발명의 바늘 끝의 경사각 short-bevel로 경사각이 18°~ 45°을 사용하는 것이 바람직하다.In general, the inclination of the needle tip of the long-bevel needle is 12° (±2°), and it is preferable to use the inclination angle of 18° to 45° as the short-bevel of the needle tip of the present invention.
