Abstract
Formation of a sterile connection includes inserting a first aseptic coupling device into a second aseptic coupling device while a locking ring of the first aseptic device is in an indexed initial position, rotating the locking ring to a secured position in which a compressive force is created and in which a first membrane from the first aseptic coupling device and a second membrane from the second aseptic coupling device can removed thereby resulting in a first a first sealing member of the first aseptic coupling device sealing with a second sealing member of the second aseptic coupling device to form a sterile fluid passageway.
Claims19
A first aseptic coupling device for coupling to a second aseptic coupling device, the first aseptic coupling device comprising:
- a first main body defining a first longitudinal axis, a first face, and a first fluid passage therethrough that extends in a direction parallel to the first longitudinal axis;
- a first sealing member received at least partially within the first main body;
- a first membrane attached to the first face of the first main body to cover the first sealing member, wherein the first membrane is folded over such that the first membrane will roll on itself and detach from the first face as the first membrane is pulled away from the first main body;
- and
- a first handle attached to the first membrane and configured to attach to a second handle of the second aseptic coupling device, the first handle defining an open area that is beyond an end of the first membrane and configured to receive a finger of a user, the open area at least partially bordered by an exposed edge of the first handle against which the finger of the user can apply a force to detach the first membrane from the first face while the finger is in the open area, and wherein the first handle includes a post and a post receptacle by which the first handle is connectable to the second handle of the second aseptic coupling device.

A second aseptic coupling device for coupling to a first aseptic coupling device, the second aseptic coupling device comprising:
- a second main body defining a second longitudinal axis, a termination end, and an opposite end comprising a second face, the second main body defining a second fluid passage extending longitudinally therethrough that extends in a direction parallel to the second longitudinal axis between the termination end and the second face;
- a second sealing member received partially within the second main body and extending partially outside the second main body beyond the second face;
- a second membrane coupled to the second face to cover the second sealing member, wherein the second membrane is folded over such that the second membrane will roll on itself and detach from the second face as the second membrane is pulled away from the second main body;
- a second handle attached to the second membrane and configured to attach to a first handle of the first aseptic coupling device, the second handle defining an open area that is beyond an end of the second membrane and configured to receive a finger of a user, the open area at least partially bordered by an exposed edge of the second handle against which the finger of the user can apply a force to detach the second membrane from the second face while the finger is in the open area, wherein the second handle includes a post and a post receptacle by which the second handle is connectable to a first handle of the first aseptic coupling device;
- and
- one or more second stand-off protrusions extending from the second face to limit movement between the first aseptic device and the second aseptic device.

An aseptic coupling arrangement, comprising:
- a first aseptic coupling device comprising:
- a first main body defining a first longitudinal axis, a first face, and a first fluid passage therethrough that extends in a direction parallel to the first longitudinal axis;
- a first sealing member received at least partially within the first main body;
- a first membrane coupled to the first face and covering the first sealing member, wherein the first membrane is folded over such that the first membrane will roll on itself and detach from the first face as the first membrane is pulled away from the first main body;
- and
- a first handle attached to the first membrane and configured to attach to a second handle of the second aseptic coupling device, the first handle defining an_open area extending parallel to the first longitudinal axis and configured to receive a finger of a user that is inserted while the finger extends parallel to the first longitudinal axis, the open area at least partially bordered by an exposed surface of the first handle that extends parallel to the first longitudinal axis and against which the finger of the user can apply a force to detach the first membrane from the first face while the finger is in the open area;
- and
- a second aseptic coupling device comprising:
- a second main body defining a second longitudinal axis, a second face,_ and a second fluid passage therethrough that extends in a direction parallel to the second longitudinal axis;
- a second sealing member received at least partially within the second main body;
- a second membrane coupled to the second face to cover the second sealing member, wherein the second membrane is folded over such that the second membrane will roll on itself and detach from the second face as the second membrane is pulled away from the second main body;
- and
- a second handle attached to the second membrane and configured to attach to the first handle of the first aseptic coupling device, the second handle defining a second open area extending parallel to the second longitudinal axis and configured to receive the finger of the user that is inserted while the finger extends parallel to the second longitudinal axis, the second open area at least partially bordered by a second exposed surface of the second handle that extends parallel to the second longitudinal axis against which the finger of the user can apply a second force to detach the second membrane from the second face, wherein the second open area is aligned with the first open area.
