Closable male luer connector

Abstract

A male luer connector is disclosed, the male luer connector being attached to a first tube and connectable to a female luer connector for providing a flow channel from said first tube to said female luer connector. The male luer connector includes a male luer part, which includes a tapered outer peripheral wall, a side wall, and an outlet opening. A tube member is also provided, the tube member having a flow channel therein. The tube member has openings at first and second ends thereof, the first end being movably inserted into an inner space of the side wall and the second end being connected to the first tube. The tube member further includes a male luer part sealing arrangement for sealing the outlet opening.

         9 . A male luer connector attached to a first tube and connectable to a female luer connector for providing a flow channel from said first tube to said female luer connector, wherein said male luer connector comprises:
 a male luer part including:
 a tapered outer peripheral wall being capable of sealingly contacting a tapered inner peripheral wall formed within said female luer connector, said tapered outer peripheral wall tapering toward a tip end thereof; 
 a side wall having an inner side wall forming an inner space; and 
 an outlet opening formed at a smaller diameter end surface of said side wall; and 
   a tube member provided with a flow channel therein, said tube member having openings at first and second ends thereof, said first end being movably inserted into said inner space and said second end being connected to said first tube, said tube member further comprising a male luer part sealing arrangement for sealing said outlet opening.   
     
     
         10 . The male luer connector according to  claim 9 , wherein said male luer part includes a tube member sealing arrangement for sealing the opening formed at the first end of said tube member. 
     
     
         11 . The male luer connector according to  claim 10 , wherein said male luer part includes a bridging part across said outlet opening. 
     
     
         12 . The male luer connector according to Claim  9 , wherein at least one of said male luer part and said tube member includes a filter relatively permeable to gas and relatively impermeable to liquid. 
     
     
         13 . The male luer connector according to  claim 9 , wherein a seal member is provided between said inner side wall and the outer periphery of said tube member. 
     
     
         14 . The male luer connector according to  claim 9 , further comprising an activating mechanism arranged to act on said tube member to move said tube member in an axial direction relative to said male luer part. 
     
     
         15 . The male luer connector according to  claim 9 , further comprising an urging mechanism for cooperatively moving said tube member relative to said male luer part upon connection of the male luer connector and said female luer connector to unseal said outlet opening. 
     
     
         16 . The male luer connector according to  claim 15 , wherein said urging mechanism is a support arm fixed to said tube member and positioned so as to contact with an end surface of said female luer connector. 
     
     
         17 . The male luer connector according to  claim 9 , further comprising a lock member having a first inner threaded part for connection to said female luer connector. 
     
     
         18 . The male luer connector according to  claim 17 , wherein said lock member includes a second inner threaded part configured to engage with the outer periphery of said tube member, the first and second inner threaded parts having a common screw thread orientation. 
     
     
         19 . (canceled) 
     
     
         20 . A male luer connector for connecting to a female luer connector comprising:
 a male luer inner part including:
 a tapered outer peripheral wall for sealing against a tapered inner peripheral wall of said female luer connector; 
 a side wall having an inner wall defining an inner space; and 
 an outlet opening formed at an end thereof; 
   a movable tube member arranged at least partly within said male luer inner part, said tube member having openings at first and second ends thereof, said first end being movably inserted into the inner space; and   a closure for providing a liquid tight seal to an end of said movable tube member.   
     
     
         21 . The male luer connector according to  claim 20 , further comprising a housing arranged at least partially around said male luer inner part and defining an inner space and wherein said closure includes an elastic seal member having a stretch hole, said seal member extending across said inner space and wherein said male luer connector further includes an activating mechanism for moving said movable tube member in an axial direction upon connection of said male luer connector to said female connector so as to urge said movable tube member against said closure and to open said stretch hole. 
     
     
         22 . The male luer connector according to  claim 21 , wherein said activating mechanism is a support arm fixed to said moving body tube and positioned so as to contact with an end surface of said female luer connector. 
     
     
         23 . The male luer connector according to  claim 20 , wherein said male luer inner part includes a sealing arrangement for providing said closure for sealing an opening at said first end of said movable tube member. 
     
     
         24 . (canceled) 
     
     
         25 . The male luer connector according to  claim 20 , wherein at least one of said male luer inner part and said movable tube member includes a filter permeable to gas and substantially impermeable to liquid.
