Abstract
A medical connector includes a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end, a helical thread extending radially outward from a surface of the sidewall and comprising a crest portion, flank portions, and a root portion with the flank portions connecting the crest portion to the root portion, and at least one deformable protrusion extending radially outward from the root portion of the helical thread.
Claims18
A medical connector comprising:
- a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end;
- a helical thread extending radially outward from a surface of the sidewall and comprising a crest portion, flank portions, and a root portion, the flank portions connecting the crest portion to the root portion;
- and
- a deformable portion comprising a score or notch as an initiation point for deformation, the deformable portion configured to deform when engaged by a mating connector such that friction and retention torque increases during connection of the medical connector to the mating connector, the deformable portion being configured to provide tactile feedback to a user as the connection between the medical connector and the mating connector becomes progressively tighter.
