Abstract

A connector assembly for sterile connection of two internally sterile containers or tubings comprises two connectors (3, 4). The first connector (3) has a male part (5) inside a housing (6), a connecting device to connect the first connector to a first container or tubing (1), a first deformable barrier (7) spaced from the male part (5) and a chamber (8) between the male part (5) and the first barrier (7). The second connector (4) comprises a female part (9), a connecting device to connect the second connector to a second container or tubing (2) and a second deformable barrier (11) closing the female part (9). In connecting the connectors (3, 4) first both deformable barriers (7, 11) are brought into contact with each other after which the male part (5) of the first connector (3) is put through the second barrier (11) closing the female part (9) of the second connector (4). To guarantee that during each coupling and disconnecting procedure the absolute sterility of the interior of the female part is maintained, the second barrier (11) is mounted in the entrance part of the female part (9) and is pushed entirely through the first barrier (7) during the connection of the connectors (3, 4) into the chamber (8) between the male part (5) and the first barrier (7) before the male part (5) can penetrate the second barrier (11). Further at least the second barrier (11) consists of a resilient material which during the disconnecting procedure of the connectors will be restored in the chamber (8) into the original closing position.

Claims

1. In a connector assembly for sterile connection of two internally sterile containers or tubings, comprising:

a first connector having a male part inside a housing, a connecting device to connect said first connector to a first container or tubing, and a first deformable barrier spaced from the male part to define a chamber between said male part and said first barrier, and

a second connector having a female part, a connecting device to connect said second connector to a second container or tubing, and a second deformable barrier closing the female part,

wherein by connecting said first and second connectors, both of said deformable barriers are brought into contact with each other so that the male part of the first connector is pushed through the second barrier, closing the female part of the second connector,

the improvement wherein said second barrier is mounted in the female part so that said second barrier is pushed entirely through said first barrier during the connection of said first and second connectors, and into the chamber between said male part and said first barrier, before the male part can penetrate said second barrier, and wherein at least the second barrier is comprised of a resilient material which during disconnection of said first and second connectors is restored in said chamber in the original, closing condition.

2. The connector assembly of claim 1, wherein the first barrier is also comprised of a resilient material which behaves as an air tight closure ring around the female part when the female part is pushed through the first barrier, and which is restored in the original, closing condition during said disconnection of the first and second connectors.

3. The connector assembly of claims 1 or 2, wherein a housing associated with the first connector is mounted to slide telescopically along a housing associated with the second connector, and wherein said housings are provided with cooperating positioning members for fixing a first position in which a very small distance is maintained between the barriers.

4. The connector assembly of claim 3, wherein said housings are provided with cooperating positioning members for fixing a second position in which the male part takes its final position in the female part.

5. The connector assembly of claim 4, wherein the positioning members are snap members.

6. The connector assembly of claim 4, wherein the positioning members are a double bayonet closure.

7. The connector assembly of claim 3, wherein the positioning members are snap members.

8. The connector assembly of claim 3, wherein the positioning members are a double bayonet closure.

9. The connector assembly of claim 1, wherein the chamber of the first connector communicates with the exterior through a channel provided with a bacterial filter.
