  • Publication number: 20140221913
    Abstract: A low profile and volumetrically efficient medication delivery device configured to be placed on the body of a patient during fluid delivery to the patient is provided. The device incorporates a low profile actuator assembly that causes fluid delivery by displacing a collapsible reservoir in response to receiving an electrical current or charge input from a programmable controller and a power supply. Additional components help prevent drug theft or abuse, measure actuator pressure, displacement and temperature in real time providing active feedback to the controller that is controlling the actuator. The device also has wireless communication capabilities.

  • Patent number: 5788674
    Abstract: A detachable apparatus for limiting the rate at which a fluid is supplied to a patient by a positive pressure infusion device. The infusion device has an operating device pressure of at least approximately 2 psi. The apparatus includes a constrained flow segment (or CFS), coupleable to and detachable from the infusion device, for delivering fluid to the patient from the infusion device. The CFS has a length, an inside diameter, and a hydraulic resistance. The hydraulic resistance is a function of the length and inside diameter. When the apparatus is not in a free-flow condition, the CFS delivers fluid to the patient at a controlled flow rate determined by the operating device pressure and the hydraulic resistance of the CFS. When the apparatus is in a free-flow condition, the hydraulic resistance of the CFS limits a maximum flow rate of the apparatus to less than about 50% of the controlled flow rate.

  • Patent number: 5743878
    Abstract: An infusion pump for infusing a medical treatment fluid intravenously to a patient includes a collapsible treatment fluid bag juxtaposed with an inflatable drive fluid bladder confined between a pair of opposing containment members which cause the bladder to impinge against the bag as the bladder is inflated. A drive fluid pump controllably inflates the bladder, thereby displacing treatment fluid from the bag into an outlet tube affixed thereto which conveys the treatment fluid to the patient where it is received intravenously. The treatment fluid flow rate through the tube is controlled by increasing or decreasing the drive fluid pump output and consequently the pressure in the bladder in response to a pressure sensor in fluid communication with the bladder. Alternatively, the treatment fluid flow rate is adjusted by opening or closing the outlet tube by means of an occluder or restrictor positioned along the tube.
