Description

주사기 보조 장치Syringe Assist Device
본 발명은 주사기 보조 장치에 관한 것으로, 더욱 상세하게는 한 손으로도 주사기 조작을 원활하게 수행할 수 있게 하고, 구조의 간소화를 이룰 수 있도록, 구조가 개선된 주사기 보조 장치에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a syringe assisting device, and more particularly, to a syringe assisting device having an improved structure for smoothly performing a syringe operation with one hand and simplifying the structure.
의료의 개별화 및 전문화가 이루어 지면서 보다 안전한 방법으로 시술을 하기 위한 여러 기구가 개발 되고 있다.As personalization and specialization of medical care have been made, various devices have been developed in order to perform procedures in a safer manner.
주사기의 경우 약물을 인체에 주입하기 위해 아주 오래전부터 사용 되었던 기구로, 최근에 초음파와 같은 영상 기기들의 발달에 따라 직접 병변 부위를 보면서 주사기로 약물 주입이 가능하게 되었다.In the case of a syringe, it is a device that has been used for a long time to inject a drug into the human body. Recently, with the development of an imaging device such as an ultrasonic wave, a drug can be injected by a syringe while looking directly at a lesion site.
이러한 방법으로 의료행위를 할 때, 초음파 프로부를 한 손으로 잡고 있어야 하기 때문에, 다른 한손 만으로 주사액을 주입하기에는 어려움이 따르며, 시술자가 힘이 들고 그에 따른 정확도가 떨어지게 되는 부작용이 있다.In this way, when performing medical treatment, it is necessary to hold the ultrasound probe with one hand. Therefore, it is difficult to inject the injection solution with the other hand alone, and there is a side effect that the operator becomes stronger and the accuracy thereof is lowered.
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.In order to overcome such disadvantages, the prior art disclosed in Korean Patent Registration No. 10-1328443 has been proposed as a prior art. However, this prior art merely provides a stable support for the auxiliary device of the syringe by merely fitting the syringe to the auxiliary device It has a disadvantage in that it has a complicated structure due to an unnecessary structure such as not being able to be implemented and an adsorption means other than a syringe being provided, resulting in poor efficiency of use.
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.The prior art disclosed in U.S. Patent Application Publication No. US 2015/0174326 A1 also provides a solid support for the syringe auxiliary device but requires a separate connection mechanism for connecting the pusher of the syringe to the delivery screw As a result, the efficiency of coupling and disconnection of the syringe to the auxiliary device is reduced.
