Abstract

본 발명에 의한 투석액 펌프는, 내부에 수용 공간이 마련된 하우징, 적어도 일부가 수용 공간에 수용되는 투석액 공급 튜브 및 투석액 회수 튜브, 수용 공간에 회전 가능하게 설치되는 캠, 캠을 회전시키기 위한 모터, 캠에 의해 밀릴 수 있도록 수용 공간에 이동 가능하게 설치되는 제 1 역류 방지용 가압부재 및 제 2 역류 방지용 가압부재를 포함한다. 투석액 공급 튜브는 수축 및 이완할 수 있는 유연한 재질로 이루어지고 일단은 투석액 공급 탱크와 연결되며 타단은 혈액 투석 필터와 연결된다. 투석액 회수 튜브는 수축 및 이완할 수 있는 유연한 재질로 이루어지고 일단은 투석액 회수 탱크와 연결되며 타단은 혈액 투석 필터와 연결된다. 캠은 투석액 공급 튜브 및 투석액 회수 튜브를 가압하여 투석액 공급 튜브 및 투석액 회수 튜브 내부의 투석액을 토출시키기 위한 캠 면을 갖는다. 제 1 역류 방지용 가압부재 및 제 2 역류 방지용 가압부재는 투석액 공급 튜브 및 투석액 회수 튜브를 통한 투석액의 역류를 방지한다.
