Patent number: 8939928Abstract: Provided is a wearable, self-contained drug infusion or medical device capable of communicating with a host controller or other external devices via a personal area network (PAN). The medical device utilizes a PAN transceiver for communication with other devices in contact with a user's body, such as a physiological sensor or host controller, by propagating a current across the user's body via capacitive coupling. The wearable nature of the medical device and the low power requirements of the PAN communication system enable the medical device to utilize alternative energy harvesting techniques for powering the device. The medical device preferably utilizes thermal, kinetic and other energy harvesting techniques for capturing energy from the user and the environment during normal use of the medical device. A system power distribution unit is provided for managing the harvested energy and selectively supplying power to the medical device during system operation.Type: GrantFiled: July 23, 2009Date of Patent: January 27, 2015Assignee: Becton, Dickinson and CompanyInventors: Richard Savoie, Gary Searle

Patent number: 8506535Abstract: A gas vent valve assembly may be attached or incorporated to a disposable fluid transfer set used with a fluid warmer to administer an infusate to a patient. The gas vent valve assembly has a housing having a fluid inlet, a gas outlet and a fluid outlet. The gas outlet is located at the top of the housing while the fluid outlet is located at the bottom of the housing. The fluid inlet is located at a side lower portion of the housing. Inside the housing is an actuator float that has an upper seal and a lower seal. The dimension of the float relative to the chamber of the housing is such that the float is freely movable within the housing to an upper position whereby its upper seal closes the gas outlet while the fluid outlet is opened, and to a lower position whereby its lower seal closes the fluid outlet and the gas outlet is opened. The movement of the float is dependent on the respective amounts of air and fluid in the housing, and the buoyancy of the float relative to the fluid in the housing.Type: GrantFiled: January 23, 2009Date of Patent: August 13, 2013Assignee: Smith Medical ASD, Inc.Inventors: Eric Andersen, Rene Robert, Gary Searle, Vincent Waldron

Publication number: 20130046366Abstract: The inventive flexible structure has at least two heat transfer portions. One of heat transfer portions is positioned in contact with the body of the patient. The structure is hermetically sealed and a fluidized medium responsive to temperature change is provided in the structure between the heat transfer portions. The fluid is changeable between a liquid state and a gaseous state, when it is exposed to heat and cold. The heat absorbed by the heat transfer portion in contact with the patient is carried by the fluidized medium, as latent heat in the gas that results when the liquid is vaporized to its gaseous state, to the heat transfer portion layer not in contact with the patient, so that the latent heat in the gaseous vapor is dissipated. Upon dissipation, the gaseous vapor is condensed and the fluidized medium returns to its liquid state.Type: ApplicationFiled: September 13, 2012Publication date: February 21, 2013Applicant: SMITHS MEDICAL ASD, INC.Inventors: Francis L. Ross, III, Gary Searle

Publication number: 20130006216Abstract: A drug delivery device (100) for administering a low dose of a medicament includes a housing (111) and a drug reservoir (101) disposed in the housing (111). A needle (135) is connected to the drug reservoir (101). A pressure applying member (113) is movably connected to the housing (111) and is movable between first and second positions. The pressure applying member (113) does not apply pressure to the drug reservoir (101) in the first position and applies pressure to the drug reservoir (101) in the second position to dispense medicament stored in the drug reservoir (101). A method of administering a low dose of insulin to simulate a first-phase insulin response of a pancreas is also disclosed.Type: ApplicationFiled: January 31, 2011Publication date: January 3, 2013Inventors: Margaret Taylor, James Bates, Roman Tunkel, Jay Butterbrodt, Gary Searle, Joshua Horvath, Keith Knapp, II, Edward Gillen

Publication number: 20120029431Abstract: A reservoir and straight-line, push-on connector assembly is provided for connecting the reservoir and one of a standard Luer line set and a custom Luer line set to any number of infusion pump configurations using a simple straight-line, push-on motion, wherein the push-on connector assembly is provided and configured to secure the line set and reservoir with the infusion pump. One simple straight-line, push-on motion, preferably performed by gripping an expander sleeve, places and secures the reservoir (i.e., locates the reservoir on the x, y, and z axes) in the pump reservoir cavity, and one simple straight-line, pull-off motion releases and removes the reservoir from the pump reservoir cavity. Rotational orientation is not required for connection, pump engagement, or pump function, and any pulling of the tube set will not release the reservoir as the expansion sleeve through which the tube set is routed is not moved from the securing position by tension on the tube set or Luer fitting.Type: ApplicationFiled: July 25, 2011Publication date: February 2, 2012Inventors: Charles Hwang, Gary Searle

Patent number: 8021353Abstract: A connector assembly for a heat exchanger has a fitting and a mount to which the fitting couples. The fitting has an elongate body having a proximal portion and a distal portion. At the proximal portion there is a crossbar, and at the distal portion there are an inlet and an outlet that protrude away from the body. Two wings extend from the body in a direction opposite to that of the inlet and outlet. There is formed on each of the wings a locking protrusion. The mount has a top portion where there is a groove dimensioned to accept the crossbar of the fitting. A longitudinal channel is formed orthogonal to the groove in the mount. Two sidewalls extend from the mount each for accepting a corresponding one of the wings, when the fitting is coupled to the mount. Apertures are provided at the sidewalls at the wings.Type: GrantFiled: March 17, 2009Date of Patent: September 20, 2011Assignee: Smiths Medical ASD, Inc.Inventors: Eric Andersen, David Baker, Gregory Hughes, Liam O'Shea, Gary Searle
