Neutral displacement medical connector

A medical connector defining a main axis, the medical connector comprising:

• a body member having a first end and a second end distal to the first end, a base member that is coupled to the body member, and an internal cavity formed between the body member and the base member, the first end of the body member defining a central opening for receiving a male luer tip of a medical implement to deliver fluid through the central opening;
• the body member further including an internal abutment surface located in-between the central opening and the second end of the body member along the main axis, the abutment surface having a proximal end, a distal end, and a slanting wall extending between the proximal end and the distal end such that the proximal end of the abutment surface is narrower than the distal end of the abutment surface;
• and
• a rigid, hollow elongated portion located within the cavity;
• wherein the elongated portion includes a body portion and a proximal tip that is more proximal to the first end than the body portion,
• the body portion being tapered, such that a radial width of the body portion decreases towards the proximal tip;
• the elongated portion defining one or more side openings on the body portion, and including an internal fluid passageway in fluid communication with the one or more side openings, the one or more side openings having a first end and a second end, the first end of the one or more side openings being relatively closer to the central opening when compared to the second end of the one or more side openings, the first end of the one or more side openings positioned distally of the distal end of the abutment surface, wherein the one or more side openings have a pyriform geometry, the first end of the one or more side openings being more pointy when compared to the second end of the one or more side openings.

A medical connector defining a main axis, the medical connector comprising:

• a body member defining an internal cavity and having a first end and a second end spaced from the first end, the first end defining a central opening that communicates with the internal cavity, the body member having an internal abutment surface including a proximal end and a distal end;
• a base member coupled to the second end of the body member;
• and
• an elongated portion extending from the base member into the internal cavity of the body member along the main axis, the elongated portion defining a passageway and at least one side opening;
• wherein the internal abutment surface is positioned between the central opening and the base member, and the at least one side opening is positioned in its entirety between the distal end of the abutment surface and the base member, wherein the elongated portion has a radial width that decreases along the main axis from the base member towards the central opening, and the at least one side opening has a proximal first end and a distal second end, the proximal first end positioned closer to the central opening than the distal second end, and wherein the distal second end of the at least one side opening has a greater width than the proximal first end of the at least one side opening.
