Abstract
Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. An elastomeric seal without a guide member is positioned within the internal cavity. A rigid, hollow elongated portion is located within the internal cavity such that in an open configuration, a tip of the elongated portion is more proximal than a proximal surface of the elastomeric seal.

A medical connector comprising:
- a housing comprising a proximal region and a base region;
- the proximal region comprising:
- a proximal opening, a slanted internal abutment surface, and a distal portion comprising a first plurality of longitudinally extending protrusions;
- and the base region comprising:
- a proximal portion with a second plurality of longitudinally extending protrusions, the second plurality of longitudinally extending protrusions of the base region being interposed between the first plurality of longitudinally extending protrusions of the proximal region;
- a rigid, hollow elongated portion that is stationary with respect to the housing, the elongated portion comprising a proximal tip positioned within the proximal region, an external surface, an internal surface, and an internal fluid passageway within the elongated portion;
- and
- an elastomeric seal with a closed position and an open position, the seal comprising:
- a proximal end that is located in a position to permit effective antiseptic wiping, a collar,
- an o-ring adjacent to and proximal from the collar, and a distal end, an external surface, and an internal surface, the collar of the seal comprising a proximal end and a distal end;
- wherein the seal is integrally formed of a single piece of material from the proximal end of the seal to the distal end of the seal adjacent to the base region of the housing;
- wherein in the closed position, a first portion of the internal surface of the seal that is proximal from the distal end of the collar is adjacent to the external surface of the elongated portion, a second portion of the internal surface of the seal that is proximal from the first portion of the internal surface of the seal is spaced from the external surface of the elongated portion, and a third portion of the internal surface of the seal that is proximal from the second portion of the internal surface of the seal is adjacent to the external surface of the elongated portion;
- and
- wherein no guide member surrounds the collar;
- wherein in the closed position, the collar contacts the internal abutment surface of the proximal region, thereby stopping proximal axial movement of the seal;
- and
- wherein in the open position, the collar is separated from the internal abutment surface, and the proximal tip of the elongated portion passes through the proximal end of the seal such that the proximal end of the seal is distal from the proximal tip of the elongated portion.
