Abstract:
PROBLEM TO BE SOLVED: To provide a system for the preparation and delivery of intravenous drugs, which reconstitutes a powdered drug to a liquid.SOLUTION: A system includes: a liquid inlet for connection to a liquid supply; a vial 11; and a liquid outlet for providing the intravenous drug in a mixed liquid form to a patient. The system may include a chamber having a variable volume, and a valve mechanism, which may be actuated to control flow between the liquid outlet, the variable-volume chamber, the vial and the liquid inlet. The system induces change in the volume of the variable-volume chamber and actuates the valve mechanism, so as to introduce liquid from the liquid inlet into the vials and reconstitute or dilute the drugs and so as to deliver the drugs to the patient. In a preferred embodiment, the liquid inlet, the vials, the variable-volume chamber, the liquid outlet and the valve mechanism are located in a disposable cassette 17, which may be received in a control unit 15.

PROBLEM TO BE SOLVED: To provide a preparing and delivering system for intravenous drugs which system may return a powder drug to liquid. SOLUTION: The system comprises a liquid inlet 22 for connection to a liquid supply, vials 11a-11c, and a liquid outlet 23 for delivery an intravenous drug in a mixed liquid form to a patient. The system may include a delivery chamber 27, a mixing chamber 28, and valve mechanisms 31a-31i. The valve mechanisms may be actuated to control flow between the liquid outlet 23, the delivery chamber 27, the mixing chamber 28, the vials 11a-11c, and the liquid inlet 22. The system changes volumes of the delivery chamber 27 and the mixing chamber 28 and actuates the valve mechanisms 31a-31i to guide the liquid from the liquid inlet 22 to the vials 11a-11c to liquefy or dilute the drug to deliver the drug to the patient. The liquid inlet 22, the vials 11a-11c, the delivery chamber 27, the mixing chamber 28, the liquid outlet 23, and the valve mechanisms 31a-31i are placed in a disposable cassette storable in a controller.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical sensor for a delivery device.SOLUTION: The optical sensor for the delivery device has a piston (30) that displaces a substance, such as a fluid, from a reservoir (34). The optical sensor has a light source (42) and a detector array (44) for imaging encoding features disposed along a plunger rod (38) coupled to the piston. By virtue of the pattern of encoding features, an absolute position of the plunger rod relative to a fiducial position may be determined uniquely. Thus, the volume of fluid remaining in the reservoir, the rate of fluid delivery, and proper loading of the reservoir may be accurately ascertained. Additionally, the encoding may serve to uniquely identify a version of the reservoir which may be supplied in various versions corresponding, for example, to differing concentrations of a therapeutic agent to be dispensed.

Abstract:
A system for pairing a controller and an infusion pump is disclosed. The system includes an infusion pump, a controller device and a user interface residing on both the infusion pump and the controller. The user interface includes a pairing mode for enabling wireless communication between the infusion pump and the controller device, wherein the user interface requires both the infusion pump and the controller to be in the pairing mode simultaneously. Also, a method of changing a power source in a infusion pump is disclosed. The method includes placing the infusion pump in idle mode wherein the infusion pump stops delivery. Removing the first power source from the infusion pump. Replacing the first power source with a second power source in the infusion pump, and maintaining the insulin on board during the changing of the first power source with the second power source.
Abstract:
A system is disclosed. The system includes a fill adapter device (700) including a heat exchanger which includes a heating element (706) and a fluid pathway (712), the fluid pathway fluidly connected to a filling needle input (714), whereby fluid enters the heat exchanger through the filling needle input and flows through the fluid pathway and whereby the fluid is heated by the heating element. The system also includes a reservoir (704) including a plunger (708) and a plunger rod and a filling needle (710) configured to be removably attached to the reservoir, wherein the fill adapter is configured to be attached to a vial (702) of fluid and wherein fluid from the vial flows through the fluid pathway and is heated and loaded into the reservoir through the filling needle.
