A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.

An apparatus for starting operation of a motor of an implantable blood pump including a memory storing one or more default parameters for at least one of controlling and monitoring the startup operation. A processor operatively coupled to the motor is included, the processor is configured to: commence the startup operation based on the one or more default parameters; detect an error during the startup operation; adjust at least one of the one or more default parameters in response to the detected error; store the at least one adjusted parameter in the memory; and commence subsequent startup operations based at least in part on the at least one adjusted parameter.

Vaporizer devices and methods for detecting inhalation through a vaporizer using a heating element are provided. A resistive heater of a vaporizer may function as both a heater and as an anemometer to detect inhalation. Alternatively or additionally, a separate resistive heater may be included in an air path through the vaporizer to detect a user inhaling through the vaporizer. A heating control mechanism utilizes the already existing heating element in an anemometric correlation to when the vaporizer is idle and when it is being used (where being used implies the user is taking a puff/inhalation on the vaporizer). Using this information, a controller of the vaporizer accordingly controls heating to the vaporizer as required.

With certain implementations, the configuration is such that a controller uses a first driver to move a pharmaceutical syringe attachment component closer to the distal end side than a needle removal position when a needle unit is attached to a pharmaceutical syringe unit or when the needle unit is removed from the pharmaceutical syringe unit, so when an injection needle is attached to the pharmaceutical syringe unit, or when the injection needle is removed from the pharmaceutical syringe unit, these operations can be executed without removing a distal end cap, which makes the device extremely convenient to use.

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.

A control apparatus for an implantable heart pump is provided, which comprises an implantable first control unit, which is electrically connected to the heart pump in a main operating state for controlling operating parameters of the heart pump. The control apparatus also comprises an interface, which is electrically connected to the first control unit and is intended to wirelessly transcutaneously transmit data and/or to wirelessly transcutaneously transmit energy between the first control unit and a further control unit provided for extracorporeal use. The control apparatus also comprises an implantable second control unit, which is electrically connected to the heart pump in an auxiliary operating state for controlling operating parameters of the heart pump, and an implantable switch, which is electrically connected to the first control unit and the second control unit. The switch is set up to change over between the main operating state and the auxiliary operating state.

A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

A negative pressure wound therapy apparatus can include a wound dressing, a fluid collection container, a vacuum pump comprising a pump motor, and tubing. Additionally, the apparatus can include a pressure sensor that measures a pressure in the tubing. One or more tubes can channel a fluid between the wound dressing, the fluid collection canister, and the pump. In addition, first and second control circuits can be provided for controlling the pump motor without using a processor. The first control circuit can generate a difference signal between a desired pressure input and a pressure sensor input, and can further generate a motor control signal responsive to the difference signal. Moreover, a second control circuit can provide an override signal based at least in part on the difference signal and at least one reference signal. The override signal beneficially overrides the motor control signal to prevent the pump motor from stalling.
