Description
Claims (2)
- 혈액투석장치에 있어서,내부에 차단막을 구비하여 인입로와 인출로를 별도로 구비하는 주사바늘과, 상기 주사바늘에 연결되어 혈액을 수송하는 연질의 의료용 튜브와, 상기 튜브로부터 공급된 혈액을 필터링하여 다시 배출하는 혈액투석 필터와, 상기 혈액투석 필터의 일측 소정부위에 구비되어 있으며 혈액의 이동속도에 따라 소정의 전기적 신호를 발생하는 센서부와, 혈액이 상기 혈액투석 필터에서 투석될 수 있도록 구동력을 발생하는 구동부와, 상기 구동부를 제어하며 센서부에서 소정의 전기적 신호가 발생되는 경우 구동부의 동작을 중지시키는 제어부로 구성되어 있는 것을 특징으로 하는 휴대용 혈액투석기.
- 제 1항에 있어서,상기 주사바늘은 주사바늘은 내부에 차단막을 구비하여 좌측의 인출로와 우측의 인입로가 서로 소통되지 못하는 구조를 형성하고 있으며, 상기 주사바늘 인출로의 소정부위에는 혈액이 배출되도록 출혈구가 구비되어 있고, 상기 주사바늘 인입로의 소정부위에는 혈액이 유입되도록 입혈구가 구비되어 있으며, 하단부는 혈관에 삽입이 용이하도록 뾰족한 상태를 유지함과 동시에 혈액의 유입과 유출이 차단되도록 막힌 상태이고, 상단부는 의료용 튜브를 삽입했을때 쉽게 이탈하지 않도록턱이 형성되어 있는 것을 특징으로 하는 휴대용 혈액투석기.
