  • Patent number: 7766897
    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.

  • Patent number: 5240300
    Abstract: A device for hand-carrying articles in cooperation with a string, strap, shoelace or the like includes a grip element for grasping of the device by a user. Support elements extend upwardly from opposed ends of the grip element, and arm elements are connected at proximal ends thereof to the support elements. Each of the arm elements defines a distal end, and the arm elements extend inwardly toward each other from the support elements with the distal ends positioned in closely spaced apart relationship with each other to form a gap therebetween. The arm elements are configured for enabling movement of the arm elements relative to each other to vary the size of the gap, and gripping elements are provided on the distal ends of the arm elements for enabling a string, strap, shoelace or the like to be tightly gripped and held in position in the gap between the arm elements.
