Abstract
A reservoir is incorporated in between a guide portion and an introducer tip of the introducer member. A spherical or similarly shaped plug is inserted into the guide portion. The plug is designed such that it forms a seal within the guide portion, preventing any fluid flow between the reservoir and an environment external to a distal end of the guide portion. This prevents a liquid or gel contained inside the reservoir from drying or leaking. The plug may further be held in place against a distal opening of the reservoir by positive pressure within the reservoir. The plug may further be held in place within the guide portion by a plurality of bumps or notches. When the catheter is advanced through the guide portion, the catheter tip pushes the plug into the reservoir, thereby breaking the seal and lubricating the catheter.
Claims15
An introducer member for a urinary catheter assembly, the introducer member comprising:
- a plug placed in between the reservoir portion and the second opening, the plug providing a seal between the reservoir portion and an environment external to the second opening;
- wherein the plug is held in place by positive pressure inside of the reservoir;
- and
- the introducer further comprises a penetrable membrane within an introducer tip that maintains the positive pressure inside the reservoir.
A urinary catheter assembly, comprising:
- wherein a first throughbore of the guide portion has a greater diameter than a second throughbore of the introducer tip;
- wherein the plug is held in place by positive pressure inside of the reservoir;
- and
- the introducer further comprises a penetrable membrane within the introducer tip that maintains the positive pressure inside the reservoir.
