Description

주사기 조작을 위한 보조 장치Auxiliary device for syringe operation
본 발명은 주사기와 함께 사용되는 보조 장치에 관한 것으로, 더욱 상세하게는 한 손으로도 주사기 조작을 원활하게 수행할 수 있도록, 구조가 개선된 주사기 조작을 위한 보조 장치에 관한 것이다. The present invention relates to an auxiliary device for use with a syringe, and more particularly, to an auxiliary device for syringe operation with an improved structure so that the syringe operation can be smoothly performed with one hand.
의료 영역에서 초음파 기기 사용이 늘어나면서 여러 시술이 초음파로 직접 해부학적인 구조를 확인한 후에 이루어지는 경우가 많다.As the use of ultrasound devices in the medical field is increasing, many procedures are often performed after ultrasound confirms the anatomical structure.
대표적인 경우로 근육이나 관절 등에 주사기를 이용해 약물을 주입한다거나, 낭종이나 암이 의심되는 경우에 주사기를 이용해서 조직을 얻는 경우에도, 초음파를 이용하여(sono-guided) 직접 보면서 반대 손을 이용해 약물을 주입하거나 조직을 채취한다.In typical cases, a syringe is used to inject a drug into a muscle or joint, or when a cyst or cancer is suspected, even when a syringe is used to obtain tissue. Inject or collect tissue.
결국, 이러한 시술과정에 의하면 한 손으로 초음파를 쥔 상태에서 다른 손으로 주사기 조작을 하여야 하기 때문에, 원활한 조직 채취를 기대할 수 없게 된다. As a result, according to this procedure, it is impossible to expect a smooth tissue collection because the operation of the syringe must be performed with the other hand while holding the ultrasound with one hand.
이러한 단점을 보완하기 위해 등록특허공보 등록공보 제10-1328443호에 개시된 발명이 선행기술로 제안된 바 있으나, 이러한 선행기술은 주사기를 보조 장치에 단순히 끼우는 결합 만으로는 주사기의 보조 장치에 대한 안정적인 지지를 구현할 수 없음은 물론, 주사기 이외의 흡착수단이 마련되는 등 불필요한 구성이 구비됨에 따라 복잡한 구조를 가짐으로써 사용 효율이 떨어지는 단점을 가진다.Although the invention disclosed in Korean Patent Publication No. 10-1328443 has been proposed as a prior art to compensate for these disadvantages, this prior art provides a stable support for the auxiliary device of the syringe by simply coupling the syringe to the auxiliary device. Not to be realized, of course, there is a disadvantage that the use efficiency is lowered by having a complicated structure as the unnecessary configuration is provided, such as the adsorption means other than the syringe is provided.
또한, 미국공개특허공보 US 2015/0174326 A1에 개시된 선행기술은, 주사기의 보조 장치에 대한 견고한 지지를 가능하게 하기는 하나, 주사기의 밀대와 이송스크류를 연결시켜 주기 위한 연결용 기구가 별도로 마련되어야 함에 따라, 주사기의 보조 장치에 대한 결합 및 분리 과정의 효율이 떨어지는 단점을 가진다. In addition, the prior art disclosed in US 2015/0174326 A1, while enabling a solid support for the auxiliary device of the syringe, a connection mechanism for connecting the syringe rod and the transfer screw must be provided separately. As a result, the efficiency of the coupling and disengaging process for the auxiliary device of the syringe is disadvantageous.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 주사기를 한 손으로 조작할 수 있음은 물론, 주사기의 결합 및 분리 과정의 효율을 높일 수 있고 간소한 구성에 의해서도 주사기의 안정적인 지지를 가능하게 하는 주사기 조작을 위한 보조 장치를 제공하고자 하는 것이다. The present invention has been made to solve the above problems, the object of the present invention is to operate the syringe with one hand, as well as to increase the efficiency of the coupling and separation of the syringe and the syringe by a simple configuration It is an object of the present invention to provide an auxiliary device for manipulating a syringe that enables stable support.
