요도 카테터 삽입용 가이더 기구 및 이를 구비하는 요도 카테터 키트 Guide device for urethral catheter insertion and urethral catheter kit having same
본 발명은 요도 카테터를 요도에 삽입하는 기술에 관한 것으로서, 더욱 상세하게는 요도 카테터가 좁은 협착 부위를 통과하도록 사용되는 가이드 기구 및 이를 구비하는 요도 카테터 키트에 관한 것이다.The present invention relates to a technique for inserting a urethral catheter into the urethra, and more particularly to a guide mechanism and a urethral catheter kit having the urethral catheter is used to pass through the narrowed narrowing site.
요도 카테터는 환자의 방광 내 소변을 배출하기 위하여 요도를 통해 삽입되어서 사용된다. 요도 카테터는 유연하고 부드러운 재질로 이루어지기 때문에, 요도를 통한 삽입 과정에서 협착 등에 의해 좁아지는 부위를 만나는 경우 선단부가 꺾여서 진입하지 못하는 경우가 발생한다. 본 출원의 발명자는 이러한 문제를 해결하기 위하여 도 1에는 도시된 바와 같이 삽입 가이더(11)를 이용하여 요도 카테터(10)를 삽입하는 방식을 개발한 바 있다. 도 1을 참조하면, 요도 카테터(10)의 선단에는 작은 관통구(11)가 형성되어 있으며, 와이어 형태의 삽입 가이더(11)가 요도 카테터(10)의 내부 통로를 지나 관통구(11)를 통과하여 연장된다. 요도 카테터(10)가 삽입 가이더(11)에 의해 안내되면서 삽입됨으로써, 요도 카테터(10)의 선단이 좁은 협착 부위를 만나더라도 수직경도가 강한 삽입 가이더(11)에 의해 지지되어서 안정적으로 통과하게 된다. 하지만, 협착 정도가 매우 심하여 요도 카테터의 외경보다 협착 부위가 좁은 경우에는 삽입 가이드(11)를 이용하더라도 요도 카테터가 협착 부위를 통과하지 못한다는 문제가 있다.Urethral catheters are used inserted through the urethra to drain urine in the bladder of a patient. Since the urethral catheter is made of a flexible and soft material, when the urethral catheter encounters a narrowing part due to stenosis or the like during insertion through the urethra, the distal end portion may be bent to enter. In order to solve this problem, the inventor of the present application has developed a method of inserting the urethral catheter 10 using the insertion guider 11 as shown in FIG. 1. Referring to FIG. 1, a small through hole 11 is formed at the tip of the urethral catheter 10, and the insertion guide 11 in the form of a wire passes through the inner hole of the urethral catheter 10. Extend through. Since the urethral catheter 10 is inserted while being guided by the insertion guider 11, even when the tip of the urethral catheter 10 meets a narrowing narrowing position, the urethral catheter 10 is supported by the insertion guider 11 having a strong vertical hardness and stably passes. . However, when the narrowing degree is very severe and the narrowing area is narrower than the outer diameter of the urethral catheter, there is a problem that the urethral catheter does not pass through the narrowing area even when the insertion guide 11 is used.
