Abstract

A simplified aseptic connector assembly for tubes or conduits to conduct sterile fluids and comprising interconnectable complementary male and female connector members respectively connectable to the ends of tube sections to be connected, one of the members having a socket open at one end and dimensioned to slidably receive the other member which also has an axial socket open at the outer end which is adapted to be received in the socket of the one member, the axial socket in the other member being tapered and complementary in shape to a tubular prong extending axially within the socket of the one member for frictional reception within the tapered socket of the other member and the prong having a piercing tip terminating short of the open face of the open end of one member, each of the open ends of the sockets of the members initially being sealed by membranes to maintain the interiors of the sockets in aseptic condition; the sealed ends of the connector members being adapted to be dipped in a disinfecting solution and then abutted firmly to maintain sterility, followed by telescopically inserting the other member into the socket of the one member initially to cause the piercing prong to pierce both membranes and then establish the prong in firm fricitonal engagement within the tapered socket in the other member to establish a passage between tubes connected by the connector members.

Claims

1. An aseptic connector assembly for connecting conductors for sterile fluids comprising in combination, axially extending complementary male and female connector members each having tubular means integral therewith at one end and connectable to a conductor, the female member also having an axial socket on the opposite end, opening outwardly and dimensioned to slidably receive said male member longitudinally, the male member also having a tapered axial socket on the opposite end thereof opening outward and communicating with the tubular means on said one end thereof, the socket of said female member also having an axially-extending prong integral therewith and terminating in a piercing point spaced inwardly from the plane of the open end of the socket and being tapered in complement to the taper of the socket of said male member and adapted to frictionally engage said socket when inserted thereinto, and sterile sealing membranes aseptically and respectively affixed over the outer ends of both of said sockets;

said sterile membranes and the outer ends of the sockets to which they are connected being adapted to be firmly abutted and the male member inserted within the female member initially to pierce the sterile membrane affixed over the face of the socket in the female member and followed by said piercing prong puncturing the membrane affixed over the face of the socket in said male member and finally frictionally engage said piercing prong within the tapered socket in said male member to establish a sterile fluid passage through the connected members.

2. The aseptic connector assembly according to claim 1 in which said piercing point is tubular and also has an opening communicating directly with the interior of the tubular configuration of said prong.

3. The aseptic connector assembly according to claim 1 in which the length of said male member is such that when said prong of the female member is in firm frictional engagement within the socket in said male member the end of the male member which is within the socket of the female member is spaced from the inner end of said socket in the female member.

4. The aseptic connector assembly according to claim 1 in which the thickness of at least the membrane which extends across and is attached to the open end of the socket in the male member is not appreciably in excess of three microns.

5. The aseptic connector assembly according to claim 4 in which the thickness of at least the membrane which extends across and is attached to the open end of the socket in the male members is substantially one and one-half micron.

6. The aseptic connector assembly according to claim 1 in which communication between said tubular means on said female member and the interior of the socket in said member is accomplished by the prong in said female member having a longitudinal passage therein and the piercing point of said prong having an opening therethrough in communication with said passage in said prong.
