Some embodiments of an infusion pump system can employ a number of power management techniques to avoid using substantially excessive power during operation of the pump drive system. Thus, the infusion pump system can draw upon the energy supply in an efficient manner that extends the useful life on the power supply. Furthermore, the infusion pump system can be configured estimate an amount of power remaining to operate the pump system without the requirement of directly detecting the remaining charge on power supply device (e.g., without detecting the remaining charge on a battery). As such, the infusion pump system can readily inform a user of a particular estimated amount of time remaining for medicine dispensing operations.

A priming assembly for a drug delivery device includes a hub, a base connected to the hub and moveable relative to the hub between a first position and a second position, with the base defining a passageway, a cap defining an interior chamber and a passageway in fluid communication with the interior chamber, and a needle connected to the hub and positioned within the interior chamber of the cap, where the passageway of the base is in fluid communication with the passageway of the cap when the base is in the first position, and where the passageway of the base is isolated from the passageway of the cap when the base is in the second position.

A drug solution administration apparatus includes an injection unit comprising an injection member configured to inject a drug solution; a delivery unit configured to be coupled to and decoupled from the injection unit, the delivery unit comprising: a delivery member configured to deliver the drug solution to the injection member, and a delivery device configured to deliver the drug solution to the delivery member; a detection unit configured to detect whether the injection unit and the delivery unit are coupled or decoupled; and a control unit configured to control operation of the delivery device. The control unit is configured to perform at least one of (i) restricting the filling operation when the detection unit detects that the injection unit and the delivery unit are coupled, or (ii) restricting the administration operation when the detection unit detects that the injection unit and the delivery unit are decoupled.

A cassette usable with an infusion pump includes a monolithic cassette body and a segment of resiliently deformable tubing for conveying a flow of liquid. The monolithic cassette body has an integrally formed free-flow protection device including a fixed pinch element and a deflectable pinch arm having a movable pinch element. The pinch arm normally resides in a closed position wherein the pinch elements cooperate to deform the tubing segment to stop flow. The pinch arm is resiliently deflectable away from the closed position to an open position permitting flow. Deflection of the pinch arm away from the closed position spring biases the pinch arm for automatic return to the closed position. The pinch arm may be moved to the open position by operating a door of the pump when the cassette is loaded in the pump, and manually for priming when the cassette is not loaded in the pump.

Disclosed are two-piece rapidly insertable central catheter (“RICCs”), introducers, and methods. For example, an introducer and a distal catheter piece of a RICC can be combined in an introducer assembly configured to be actuated with a single finger of a hand while the introducer is held between a thumb and another finger or fingers of the same hand. A catheter-advancement hub of the introducer includes a manifold coupled to a proximal portion of a distal catheter-hub piece of the distal catheter piece. An introducer needle of a syringe of the introducer has a needle shaft extending through the manifold and a distal end of the distal catheter piece. An introducer housing is over a syringe tip, the manifold, and the proximal portion of the distal catheter piece. The introducer housing of the introducer configured to provide column strength to a catheter tube of the distal catheter piece during a venipuncture.

An electronic insulin delivery device receives glucose data from a glucose monitor and sets a bolus dose amount. The device may take the form of an insulin pen with automatic priming and accurate dosing provided by a motor in connection with an encoder. The device may communicate with and be controlled by a smart phone device. The smart phone device provides a user interface to receive user data including patient weight, insulin to carbohydrate ratio and exercise factor, and to send instructions to the device, including dose amount. The dose amount is determined taking into account glucose level and trend, and other factors. The delivery device may be in continuous communication with the glucose monitor and smart phone to provide for near real-time adjustments in glucose treatment. Glucose data, insulin injection data, and other relevant data may be stored and accessible to interested parties.

A valve and a method for administering a plurality of drug fluids to a patient are disclosed. For each drug fluid, the valve may be rotated into a selected drug position associated with the drug fluid. With the valve being in the selected drug position, a backpriming may be performed of a connector line of a drug container containing the drug fluid. Thereafter, the drug fluid may be administered with the valve being in the same selected drug position. Thereafter, the valve may be flushed, optionally while maintaining the same selected valve position.

Provided is a system for dispensing fluid. The system includes a housing defining a chamber; an inflatable bag disposed in the chamber and adapted to contain a fluid, the bag being in fluid communication with a flow path for flow of the fluid out of the bag; and a pressure source for inflating the bag to force the fluid from the bag to the flow path at a controlled rate. The bag inflates against an inner surface of the housing such that, prior to the bag being fully inflated, the fluid contained in the bag is forced from the bag at the controlled rate.

An electronic insulin delivery device receives glucose data from a glucose monitor and sets a bolus dose amount. The device may take the form of an insulin pen with automatic priming and accurate dosing provided by a motor in connection with an encoder. The device may communicate with and be controlled by a smart phone device. The smart phone device provides a user interface to receive user data including patient weight, insulin to carbohydrate ratio and exercise factor, and to send instructions to the device, including dose amount. The dose amount is determined taking into account glucose level and trend, and other factors. The delivery device may be in continuous communication with the glucose monitor and smart phone to provide for near real-time adjustments in glucose treatment. Glucose data, insulin injection data, and other relevant data may be stored and accessible to interested parties.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.
