This invention is an actuator of negative pressure wound care device, including a pump head. With the independent type pump head design that is to be butt-connected with an external detachable motor. Only the pump head, through which the waste liquid will pass, needs to be made of a bio-compatible material so as to save fabrication cost. When it is to be discarded, only the pump head needs to be treated with the medical waste treatment procedure. Moreover, when it is to be maintained, the infected pump head can be replaced independently therefore the maintenance cost can be reduced.本發明為一種負壓傷口照護裝置的致動器,其包含有一泵頭,透過獨立式泵頭的設計,來與外部的馬達可拆解式的對接,則可僅將廢液會通過的泵頭以生物相容性材料製成,以節省製造成本,且當廢棄時,僅需將泵頭以醫療廢棄物的程序處理,則可降低廢棄成本,再者於檢修時,受感染的泵頭可單獨更換,而可減少維修成本。10...殼體11...流體接頭111...生物隔離單元20...泵頭21...入口接頭22...出口接頭23...被動接頭30...入口連接管31...第一流道32...第二流道33...螺旋管40...出口連接管
