A needle-free medical connector comprises a cover body, a joint and an elastomer. The cover body has a containing chamber, a jack and a connecting port. The joint is provided with a combination part connected to the connecting port. The elastomer includes a head, a shoulder, a body and a base. The head is located in the jack and a concave hole is defined inside the head. The shoulder is laterally extended from the outer side wall of the head, and the outer side wall abuts against the inner side wall of the cover body. The top of the shoulder is formed with an annular recess. The body is arranged in the containing chamber and surrounds a hollow space, and the hollow space is connected with the concave hole. The base is arranged at the bottom of the body and abuts against the combination part. As such, when the body of the elastomer is squeezed, it can be easily bent and deformed from the folding edge.一種免針醫療連接器,包括蓋體、接頭及彈性體。蓋體具有容室、插孔及連接口。接頭包括組合部,組合部連結連接口。彈性體包括頭部、肩部、身部及底座,頭部位於插孔且其內部形成凹孔,肩部自頭部外側壁橫向延伸且其外側壁抵靠於蓋體內側壁,肩部頂端形成環凹,身部設於容室且圍構中空空間,中空空間連通於凹孔,底座設於身部底端且抵靠於組合部。藉此,彈性體的身部被擠壓時,可輕易地從折邊彎折變形。10‧‧‧蓋體11‧‧‧容室13‧‧‧第一端131‧‧‧插孔15‧‧‧第二端151‧‧‧連接口17‧‧‧壓塊171‧‧‧排水空間173‧‧‧凸部21‧‧‧組合部211‧‧‧環槽213‧‧‧氣道23‧‧‧插接部231‧‧‧插接槽25‧‧‧導管27‧‧‧流道271‧‧‧第一通道273‧‧‧第二通道31‧‧‧頭部311‧‧‧凹孔33‧‧‧肩部331‧‧‧階級333‧‧‧環凹335‧‧‧圓角35‧‧‧身部351‧‧‧中空空間352‧‧‧凹弧曲面353‧‧‧平滑曲面354‧‧‧折邊37‧‧‧底座371‧‧‧環凸3711‧‧‧環溝373‧‧‧凸塊39‧‧‧縫隙
