Description

주사바늘 위치 표시장치Needle position indicator

제1도는 본 발명의 실시예에 따른 주사바늘 위치표시장치를 나타내는 도면.1 is a view showing a needle position display device according to an embodiment of the present invention.

제2도는 본 발명의 실시예에 따른 주사바늘 위치표시장치와 주사기의 결합구조를 나타내는 도면.2 is a view showing a coupling structure of a needle position indicator and a syringe according to an embodiment of the present invention.

제3도는 경막외강 천자시 주사바늘의 위치를 나타내는 도면.3 is a view showing the position of the needle during the epidural puncture.

본 발명은 주사기의 주사바늘 끝의 인체내 삽입 위치를 확인하기 위한 주사바늘 위치표시장치에 관한 것으로, 특히 경막외강 천자시나 흉막강 천자시에 주사바늘의 끝이 경막외강이나 흉막강에 도달하였는지를 표시하기 위한 주사바늘 위치표시장치에 관한 것이다.The present invention relates to a needle position indicating device for confirming the insertion position of the syringe needle in the human body, and particularly for indicating whether the tip of the needle reaches the epidural or pleural cavity during epidural puncture or pleural cavity puncture. The present invention relates to a needle position indicating device.

부분마취는 크게 세가지로 나눌 수 있는데, 신경을 직접 차단하는 신경차단법, 경막 내에 마취약을 주입하는 척수마취 그리고 경막외강에 마취약을 주입하는 경막외 마취 등이다. 이중 경막외 마취는, 제3도에 도시된 바와 같이, 황색인대 안쪽의 경막외강에 마취약을 주사하여 마취하는 반신마취이다.Partial anesthesia can be divided into three categories: neuroblocking, which directly blocks nerves, spinal anesthesia for injecting anesthetics in the dural epidural, and epidural anesthesia for injecting anesthetics in the epidural space. Double epidural anesthesia is half-anesthetic anesthesia by injecting an anesthetic into the epidural space inside the yellow ligament, as shown in FIG.

일반적으로, 경막외 마취는 전신 마취를 필요로 하지 않거나 무통분만과 같이 장시간의 마취를 필요로 하는 경우에 있어서 주로 사용되고 있다.In general, epidural anesthesia is mainly used in cases in which general anesthesia is not required or when long anesthesia is required, such as painless labor.

경막외 마취에 있어서는 척수를 보호하고 있는 골수를 감싸고 있는 경막을 뚫지 않도록 하는 것이 중요한데, 이는 골수의 감염이 직접적으로 뇌막염과 같은 심각한 병인이 될 수 있으며, 경막외 마취에 사용되는 주사바늘의 직경이 척수 경막내 마취에 사용되는 것에 비해 훨씬 크므로 다량의 뇌척수액이 유출됨에 따른 두통등과 같은 휴유증을 유발할 수 있기 때문이다.In epidural anesthesia, it is important not to penetrate the dura enveloping the bone marrow protecting the spinal cord. Infection of the bone marrow can be a serious etiology such as meningitis, and the diameter of the needle used for epidural anesthesia This is because it is much larger than that used for spinal epidural anesthesia, which can lead to resting periods such as headaches caused by the leakage of large amounts of cerebrospinal fluid.

종래에는, 공기가 주입된 경막외 마취용 주사기를 경막외강쪽으로 단속적으로 밀어넣으면서 피스톤을 눌러보아 인대와 경막외강 사이의 내압력의 차이에 따라 발생하는 손가락에 전해지는 저항의 변화로서, 주사바늘 끝이 경막외강에 도달하였는가를 확인한 후 마취약을 이 주사바늘을 직접적으로 통하거나 별도의 관을 삽입하여 주사약을 주입하였다.Conventionally, as the change of resistance transmitted to the finger caused by the difference in the internal pressure between the ligament and the epidural space by pressing the piston while intermittently pushing the air-drained epidural anesthetic syringe toward the epidural space, the tip of the needle is the epidural space. After confirming that the anesthesia was injected directly into the needle or a separate tube was inserted into the injection.

그러나, 이와 같이 사람의 촉각에 의존하여 주사바늘끝이 경막외강에 도달하였는지 확인한다는 것은 정확도가 떨어져 실패할 확률이 높아 환자에게 있어 위험하다는 문제점이 있다.However, whether or not the tip of the needle reaches the epidural space depending on the human sense of touch has a problem in that it is dangerous to the patient because of the high probability of failure.

따라서, 본 발명의 목적은 마취용 주사바늘의 위치를 촉각이 아닌 시각으로 확인할 수 있도록하여 보다 정확하고 안전하게 주사바늘의 끝이 경막외강에 위치하도록 하는 주사바늘 위치표시장치를 제공함에 있다.Accordingly, it is an object of the present invention to provide an injection needle position indicating device that allows the position of the needle for anesthesia to be confirmed with a visual sense rather than tactile so that the tip of the needle is located in the epidural space more accurately and safely.

상기와 같은 문제점을 해결하기 위하여, 본 발명은 주사기 본체와 주사바늘의 일측단과 각각 결합되어 연통되는 주사기 본체 결합단과 주사바늘 결합단이 양측단에 형성되어 있으며, 투명체나 반투명체인 실린더와, 상기 실린더의 주사기 본체 결합단 측으로 장착되어 상기 실린더 내로의 유입만을 가능하게 하는 일방향 밸브와, 공기압에 따라 작동하며 상기 실린더의 주사바늘 결합단 측에 장착되어 주사바늘의 인체내 위치를 시각적으로 표시하는 위치변화 표시수단을 포함하는 주사바늘 위치표시장치를 제공한다.In order to solve the problems as described above, the present invention is a syringe body coupling end and the needle coupling end is coupled to each side end of the syringe body and one side of the injection needle is formed on both sides, the transparent body or translucent cylinder and the cylinder A one-way valve mounted to the syringe body coupling end of the cylinder to enable only the inflow into the cylinder, and actuated according to air pressure, and mounted to the injection needle coupling end of the cylinder to visually indicate the position of the needle in the human body. Provided are a needle position indicating device including display means.

따라서, 주사바늘 위치표시장치를 이용하여 주사바늘 끝의 인체내 위치를 시각적으로 확인함으로써 보다 정확하고 안전하게 경막외강에 오도록 할 수 있다.Therefore, by using the needle position indicator to visually confirm the position of the end of the needle in the human body can be more accurately and safely come to the epidural space.

본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

제1도와 제2도를 참조하면, 본 발명의 실시예에 따른 주사바늘 위치표시장치(1)는 주사기 본체(17)와 주사바늘(19)의 일측단과 각각 결합되어 연통되는 주사기 본체 결합단(7)과 주사바늘 결합단(9)이 양측단에 형성되어 있으며, 투명체나 반투명체인 실린더(2)와, 상기 실린더(2)의 주사기 본체 결합단(7) 측으로 장착되어 상기 실린더(2) 내로의 유입만을 가능하게 하는 일방향 밸브(11)와, 공기압에 따라 작동하며 상기 실린더(2)의 주사바늘 결합단(9) 측에 장착되어 주사바늘(19)의 인체내 위치를 시각적으로 표시하는 위치변화 표시수단인 압력변화 표시판(13)을 포함하고 있다.1 and 2, the needle position indicating device 1 according to an embodiment of the present invention is coupled to the syringe body 17 and the syringe body coupled end in communication with one end of the needle (19) ( 7) and the needle coupling end 9 are formed at both ends, and are mounted to the cylinder 2, which is a transparent body or translucent body, and to the syringe body coupling end 7 side of the cylinder 2, into the cylinder 2; One-way valve 11 to enable only the inflow of the position, which is operated according to the air pressure and mounted on the needle coupling end 9 side of the cylinder (2) to visually indicate the position of the human body of the needle (19) And a pressure change display plate 13 which is a change display means.

주사바늘(19)의 위치변화 표시수단인 압력변화 표시판(13)은 상기 실린더(2)의 주사바늘 결합단(9) 측의 공간을 제1공간(3)과 제2공간(5)으로 구분하며 내부의 공기압 변화에 따라 슬라이드 가능하게 되어 있다.The pressure change display panel 13, which is a position change display means of the needle 19, divides the space on the needle coupling end 9 side of the cylinder 2 into a first space 3 and a second space 5. And it is possible to slide according to the change of the internal air pressure.

그리고, 상기 주사바늘 결합단(9) 측의 실린더(2)에는 상기 압력변화 표시판(13)의 위치기준을 정하기 위한 기준표시선(15)이 형성되어 있다.In addition, a reference display line 15 for defining a positional reference of the pressure change display panel 13 is formed in the cylinder 2 on the side of the needle coupling end 9.

이제, 본 발명의 실시예에 따른 주사바늘 위치표시장치(1)를 사용하여 경막외 마취시 주사바늘(19) 끝이 경막외강에 도달하도록하는 과정을 설명하면 다음과 같다.Now, the process of allowing the needle 19 to reach the epidural space during epidural anesthesia using the needle position display device 1 according to the embodiment of the present invention is as follows.

먼저, 제2도에 도시된 바와 같이, 상기 주사바늘 위치표시장치(1)의 주사기본체 결합단(7)과 주사바늘 결합단(9)을 각각 주사기 본체(17)와 주사바늘(19)에 결합시킨후, 이의 주사바늘(19)을 황색인대에 찔러 넣는다. 이렇게 되면, 황색인대의 조직에 의해 주사바늘(19)의 끝이 막히게 되고 일방향 밸브(11)로 인하여 실린더(2)의 제1공간(3)과 제2공간(5)의 공기는 유출되지 않는다.First, as shown in FIG. 2, the syringe body coupling end 7 and the needle coupling end 9 of the needle position indicating device 1 are connected to the syringe body 17 and the needle 19, respectively. After binding, the needle 19 is inserted into the yellow ligament. In this case, the tip of the needle 19 is blocked by the tissue of the yellow ligament, and the air of the first space 3 and the second space 5 of the cylinder 2 does not flow out due to the one-way valve 11. .

두 번째로, 주사기 본체(17)를 이용하여 공기를 제1공간(3)에 주입하게 되는데, 제1도에 도시된 바와 같이, 공기를 주입하기 전에는 압력변화 표시판(13)이 제1공간(3)의 좌측으로 치우쳐 있다. 공기의 주입량은 기준표시선(15) 위치에 압력변화 표시판(13)이 오도록 한다. 따라서, 제1공간(3)과 제2공간(5)의 압력이 모두 인체내의 압력이나 대기의 압력보다 높은 상태가 된다.Secondly, air is injected into the first space 3 using the syringe body 17. As shown in FIG. 1, before the air is injected, the pressure change display plate 13 is formed in the first space ( 3) It is biased to the left side. The injection amount of air is such that the pressure change display panel 13 is positioned at the reference display line 15. Therefore, the pressures of the first space 3 and the second space 5 are both higher than the pressure in the human body or the pressure in the atmosphere.

마지막으로, 압력변화 표시판(13)의 움직임을 확인하면서 주사바늘(19)을 더욱 경막외강쪽으로 밀어넣는다. 주사바늘(19)의 끝이 내압력이 약한 경막외강에 도달하게 되면 제2공간(5)의 공기가 경막외강 쪽으로 빠져나가게 되어 압력변화 표시판(13)이 주사바늘 결합단(9) 측으로 움직이게 된다.Finally, the needle 19 is pushed further toward the epidural space while checking the movement of the pressure change display plate 13. When the tip of the needle 19 reaches the epidural space with weak internal pressure, the air of the second space 5 is discharged toward the epidural space, and the pressure change display panel 13 moves toward the needle coupling end 9.

이제, 주사바늘(9)의 끝이 경막외강에 도달하였으므로, 주사바늘 위치표시장치(1)를 주사바늘(19)로부터 분리하고 주사바늘(19)을 통하여 액상의 마취약을 주입함으로써 경막외 마취를 완료하게 되는 것이다.Now, since the tip of the needle 9 has reached the epidural space, the epidural anesthesia is completed by separating the needle position indicating device 1 from the needle 19 and injecting a liquid anesthetic through the needle 19. It is done.

이와 같이, 주사바늘의 끝이 경막외강에 도달하였는가를 시각적으로 표시하는 주사바늘 위치표시기를 사용하게 되면, 보다 정확하고 안전하게 경막외 마취 혹은 흉막강내 마취를 할 수 있다.As such, when the needle position indicator is used to visually indicate whether the tip of the needle reaches the epidural space, epidural anesthesia or intrapleural anesthesia may be performed more accurately and safely.
