Described herein is a medical valve connector comprising a tubular body (2) having an inlet fitting of the male luer or luer-lock type (3) with an inner tubular element (6) displaceable axially from a retracted position for closing a passage of flow towards an outlet fitting (4) to an advanced position for opening said passage of flow. A tubular body made of elastic material (15), set between the inlet and outlet fittings (3,4), tends to keep the inner tubular element (6) in the retracted position. Also the outlet fitting (4) can rotate and axially translate between a retracted position and an advanced position.本發明係說明一種醫療用閥連接器,其包含一管狀主體(2),而管狀主體(2)具有一公螺旋或旋塞閥型的入口配件(3),且入口配件(3)具有一內部管狀元件(6),內部管狀元件(6)可從一用以關閉液流通道的縮回位置朝向出口配件(4)而軸向地移動到一用以開啟液流通道的前推位置。一以彈性材質製成的管狀體(15)係設置在該入口和出口配件(3,4)之間,其會使內部管狀元件(6)保持在該縮回位置。出口配件(4)也能在一縮回位置和一前推位置之間旋轉地及軸向地移動。
