Septum actuator with insertion depth limiter and compression compensator

A catheter assembly, comprising:

• a catheter adapter having an internal lumen forming a proximal opening, a distal opening, and a fluid pathway extending therebetween;
• a blood control septum disposed within the internal lumen and dividing the fluid pathway into a forward chamber and a rearward chamber, the blood control septum having a self-sealing slit providing a pathway through the blood control septum;
• and
• a septum actuator disposed within the rearward chamber, the septum actuator having a body comprising a tip, a base, and a lumen extending therebetween, the septum actuator further having a compression compensator forming a portion of the body and positioned between the tip and the base such that when the compression compensator is compressed the body has a shorter length than when the compression compensator is uncompressed.

A septum actuator device comprising:

• a body having a tip, a base, and a lumen extending therebetween;
• and
• an insertion depth limiter coupled to the body at a position between the tip and the base;
• wherein the insertion depth limiter is positioned on the body of the septum actuator at a distance from the tip, the distance being configured to limit a critical insertion depth of the tip into the slit, the critical insertion depth being a maximum depth of the tip in the slit at which the slit is able to self-close and push the tip out of the slit.
