ABSTRACT:
A captive deadender cap for use in venting the patient side chamber of a disposable pressure transducer through a vent port. The captive deadender cap includes retention tabs formed along the internal threads of the standard Luer threads of the deadender cap and which create a resistance with the mating external threads of the female Luer fitting on the vent port. Thus the captive deadender cap is not easily removable but is held captive to the vent port. By an increase in the torque, however, the resistance may be overcome by the user and, if desired, the captive deadender cap may be fully removed from the vent port.
