Medical needle assemblies

摘要

A medical needle device (10) which is reusable and cooperates with a disposable needle assembly (14). The medical needle device (10) includes a holder (12), a needle assembly (14), and an ejector rod (18) cooperating with the holder (12). The needle assembly (14) includes a needle hub (36) and needle (38). The holder (12) has a proximal end (24) and a distal end (26) and defines an opening (42) extending therethrough. The distal end (26) has a hub socket (52) for receiving the hub (36) of the needle (38), with the needle hub (35) received in the socket (52). The ejector (18) extends into the opening (42) from the proximal end (24) of the holder (12). The ejector rod (18) is slidably received in the holder (12) and has a distal end (32) configured to engage the needle hub (36), and a proximal end (30) extending outward from the holder (12). The ejector rod (18) is used to eject the needle assembly (14) from the holder (12).
