  • Patent number: 10052474
    Abstract: The anti-back-flow devices and methods prevent fluid from leaking proximally from a catheter, but allow ready access to the catheter using any male luer device. The devices include proximal surfaces that urge open a valve in response to force from a male luer tip. The valves are associated a female luer hub and adapted to function with standard and typical non-standard male luer fittings.
    Type: Grant
    Filed: March 17, 2015
    Date of Patent: August 21, 2018
    Assignee: I-V Access Technoiogy, Inc.
    Inventors: Stephen Richard Keyser, Jessie Delgado, Theodore J. Mosler
  • Patent number: 9775973
    Abstract: This invention provides devices and methods for insertion of a catheter into a vessel. The devices include coaxial slidably mounted needle, dilator and catheter components. The methods include piercing a vessel with the needle component, dilating the pierced hole with the dilator component, retraction of the needle component, insertion of the catheter and withdrawal of the dilator.

  • Publication number: 20070038488
    Abstract: An Internet on-line insurance policy service system that facilitates real-time automated communication of policy information, adjustment of policy parameters, calculation and communication of resulting policy quotes, and implementation of policy changes, while obviating insurer personnel involvement and supervision of the communication. The system comprises a plurality of software modules relating to on-line real-time communication of existing policy information, testing of a wide range of variations in policy parameters, computing and communicating changes in policy premiums that would result from such variations, communicating desired changes in policy parameters and implementing desired policy changes. Other modules relate to communication of claims information and the providing of on-line forms.

  • Patent number: 6213513
    Abstract: A safety belt tensioner is provided for pulling a buckle part to tighten a safety belt system about an occupant. The tensioner includes a flexible member or cable having a first loop connected to the buckle part which pulls the buckle part when it is shortened, as by actuation of a power operated device such as a piston-cylinder device. To shorten the piston stroke while achieving the necessary displacement of the buckle part, the flexible member is provided with a second loop connected to the piston about a turning member thereof with one end of an anchored half of the second loop secured to a stationary part of the pretensioner, and the other loop half extending from the cylinder and connected to the portion of the flexible cable member for the buckle part. This provides about a 1:1 ratio between the length of piston travel and downward travel of the buckle part to minimize the piston travel to allow the length of the cylinder to be shorter for providing a more compact pretensioner.
