Protective priming cap for self-sealing male Luer valve
First Claim
1. A cap for a medical connector, the connector having a distal end at which is disposed a distal connection tip, the connection tip having an aperture through which fluid may flow, and the connector having an internal valve, the cap comprising:
- a reservoir device having an internal volume, a first opening at a proximal end, and a second opening;
an hydrophobic filter disposed over the second opening of the reservoir device;
wherein the proximal end of the reservoir device is shaped for engaging the connection tip of the connector so that the first opening of the reservoir device may be put into fluid communication with the aperture of the connector, the reservoir device being removable from the connector; and
an outer housing device mounted over the reservoir device and movable in relation thereto, the outer housing device covering the distal connection tip of the connector whereby it provides protection to the distal connection tip, the housing device including an engagement portion disposed to engage the internal valve of the connector;
wherein the outer housing device is movable to a first position at which it covers the distal connection tip of the connector but the engagement portion does not open the internal valve device of the connector and is movable to a second position at which the outer housing device covers the distal end of the connector and the engagement portion opens the internal valve of the connector so that fluid flow may occur between the reservoir device and the connector, the outer housing device being removable from the connector.

Abstract
A cap for use in priming a medical connector that has a distal end at which is disposed a distal connection tip with an aperture through which fluid may flow, and the connector having an internal valve. The cap has a reservoir device with an internal volume and a first opening at a proximal end that is connected with the aperture of the connection tip. The reservoir has a second opening at which is disposed an hydrophobic filter for allowing gases to vent to the atmosphere while retaining liquid in the reservoir device. Over the reservoir device is mounted a slidable housing device used to activate the internal valve of the connector to a flow configuration at which fluid flows from the connector into the reservoir device. The user monitors the reservoir device and when gas has been vented so that only liquid remains, the user slides the housing device to de-activate the connector to the non-flow configuration at which the connector draws back into itself the liquid stored in the reservoir. The cap is then disconnected from the connector with the connector being primed.

14. A method for priming a medical connector, the connector having a distal end at which is disposed a distal connection tip, the connection tip having an aperture through which fluid may flow, and the connector having an internal valve, the method comprising:
-
mounting a reservoir device having an internal volume, a first opening at a proximal end, and a second opening at which is disposed an hydrophobic filter at the connection tip of the connector with the first opening in fluid communication with the aperture of the connection tip;
activating the internal valve of the connector to a flow configuration;
allowing fluid to flow through the connector and into the reservoir;
de-activating the internal valve of the connector to a non-flow configuration; and
removing the reservoir device from the connection tip. - View Dependent Claims (15, 16, 17, 18)
