A device for delivering medicament into skin of a patient, the device having a housing, which includes a reservoir for housing the medicament, a first internal region that is sealed from fluid ingress and includes one or more components, and a second internal region that is not sealed from fluid ingress and includes one or more components. The housing also has a barrier that separates the first internal region and the second internal region, a delivery cannula that delivers the medicament into the skin of the patient, and a base including a bottom surface for orienting toward the skin of the patient. The bottom surface of the base has one or more fluid channels disposed therein and at least one of the fluid channels is in fluid communication with the delivery cannula.

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 filling member (43) in a medicament delivery device (1), the filling member (43) includes a first conduit (12) that fluidly communicates with a reservoir (4) and a second conduit (14) that fluidly communicates with a pump (3) and with the first conduit (12), wherein the filling member (43) provides two-way medicament flow that enters the reservoir (4) via the first conduit (12), exits the reservoir (4) into the first conduit (12) and the second conduit (14), and exits the second conduit (14) to the pump (3). The reservoir (4) includes a reservoir tube (44A) having one end that is formed with the reservoir (4), and the reservoir tube (44A) having another end that is press fit to the filling member (43) to establish fluid communication with the reservoir (4).

A medical liquid administration device includes a flowing portion including a flow path through which a medical liquid is to flow; a medical liquid storage communicating with the flowing portion, the medical liquid storage storing the medical liquid that is to be fed to the flowing portion; a drive mechanism comprising a motor configured to generate a driving force for feeding the medical liquid stored in the medical liquid storage to the flow path; a detection unit configured to detect whether an operating state of the drive mechanism is within a preset range; and a controller configured to determine a blockage in the flowing portion and a failure in the drive mechanism.

A medical device for infusing medical substances has activation buttons accessible on the exterior of the device housing. Activation buttons and corresponding electrical switches within the housing are configured to prevent inadvertent activation of the buttons and therefore inadvertent operation of the switches to initiate a process such as medical substance delivery to the user. The device employs overlap of respective time traces initiated by activation of the activation buttons to determine whether activation is intended and valid. These time traces do not have to be initiated simultaneously or in any particular sequence. The activation buttons can be elastomeric overmolded buttons set within cutouts in the housing, and, when depressed, make physical contact with respective switches.

A pump system is disclosed that comprises a control unit and one or more modular infusion devices removably docked to the primary control unit. Each modular infusion device comprises a pumping mechanism and a processor configured to control the pumping mechanism and communicate with the control unit. The modular infusion device is configured to manipulate a portion of a fluid delivery set to pump a fluid. The first processor and the second processor are configured to exchange one or more operating parameters when the modular infusion device is docked to the primary control unit. The modular infusion device is configured to pump the fluid after being undocked.

An infusion pump assembly includes a locking tab and a pump barrel inside a pump barrel housing, where the pump barrel accommodates a reservoir assembly. The reservoir assembly includes a reservoir and a plunger rod. The infusion pump assembly also includes a locking disc at a terminus of the pump barrel. The locking disc includes a clearance hole for the plunger rod. The locking disc also includes at least one locking tab notch in close proximity with the locking tab. The locking tab is in moveable engagement with the locking tab notch, and the reservoir moves the locking tab from a locked position to an unlocked position when the plunger rod is inserted through clearance hole. The locking disc rotates upon torque being applied to the reservoir assembly, the locking disc rotating from a non-loaded position to a loaded position with respect to the plunger rod and a drive screw.

An anesthesiology pump for automatic delivery and control of anesthetics to a patient provides a remote unit that may be carried by an anesthesiologist to improve supervision of the anesthesiology process without unnecessarily constraining the anesthesiologist's movement. The anesthesiology pump may assess one or both of a status of the anesthesiology procedure and the availability of the anesthesiologist to provide tailored alerts to the anesthesiologist when additional attention or availability may be needed. Availability may consider separation distance between the pump and the radiologist as well as express indications of availability. A set of predefined safe states permit a pump response when the anesthesiologist is not available and additional attention is required.

A system and method for monitoring and delivering medication to a patient. The system includes a controller that has a control algorithm and a closed loop control that monitors the control algorithm. A sensor is in communication with the controller and monitors a medical condition. A rule based application in the controller receives data from the sensor and the closed loop control and compares the data to predetermined medical information to determine the risk of automation of therapy to the patient. A system monitor is also in communication with the controller to monitor system, remote system, and network activity and conditions. The controller then provides a predetermined risk threshold where below the predetermined risk threshold automated closed loop medication therapy is provided. If the predetermined risk threshold is met or exceeded, automated therapy adjustments may not occur and user/clinician intervention is requested.

A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.
