摘要:
A container for receiving liquids with different concentrations of an active substance that is to be administered or dosed, wherein the container includes a hollow body and a displaceable element for expelling the liquid is located for longitudinal movement in the hollow body, and wherein the cross-sectional surface area of the hollow body is inversely proportional to the concentration of the substance, such that, with identical strokes or longitudinal movements of the displaceable element, the discharged amount of active substance remains independent of the concentration of the substance in the container.

A patient device includes a case and a user interface for interaction between a patient and the patient device. The case may include a projection unit which projects information onto a surface separate from the case. The user interface may include a display unit for displaying information relating to the patient device integrated into the case and an additional display unit for displaying information relating to the patient device, which is external to the case. The externally provided display unit may be coupled to the case such that it can be at least one of folded, tilted, pulled out or unrolled relative to the case.
摘要:
A patient device including a case and a user interface for interaction between a patient and the patient device, wherein at least a part of the user interface is separable from the case and may be used or recognized by the patient.

A device, kit, and method for transferring a liquid medicament from a supply container to a flexible reservoir container are disclosed. The device may comprise a compartment unit and an adapter unit. The compartment unit may have a sealingly closable chamber, arranged for housing the flexible reservoir container and for being fluidly connected with a pump mechanism. The adapter unit may have at least one transfer passage for transferring liquid from a supply container connected to the adapter unit to the flexible reservoir container, and a separator arranged in the transfer passage for separating gas bubbles from a liquid streaming through the transfer passage. The separator may be fluidly connected to the chamber.

A dosing unit for an ambulatory infusion device and a method of operation are disclosed. The dosing unit includes a stationary member, a movable member, and a plunger. The movable member and the stationary member, together, make a charging valve and a discharging valve. The plunger is located, at least in part, in a metering cavity of the movable member and the movable member is adapted to selectively couple and decouple a driving unit, such that, by operating the driving unit with the movable member being coupled with the driving unit, the movable member moves with the plunger to maintain a position of the plunger relative to the movable member along a displacement axis, and by operating the driving unit with the movable member being decoupled from the driving unit, the plunger is displaced while the position of the movable member is maintained.
摘要:
A dosing device for an infusion system comprises a dosing unit having a variable volume and at least one opening in fluid connection with the variable volume, through which opening the variable volume can be filled with a substance or the substance can be dispensed from the variable volume. The dosing device is operable in a first state for filling the substance from a supply conduit, in a second state for preventing filling and dispensing, or in a third state for dispensing through a dispensing conduit. No direct fluid connection exists between the supply conduit and the dispensing conduit at any time. Methods for dosing a substance with the dosing device.

Cannula assemblies with pressure sensors made of stacked coplanar layers and ambulatory infusion systems comprising the same are disclosed. The cannula assemblies include a hub and an infusion cannula. The hub includes a pressure sensor and a fluid channel fluidly coupled to the infusion cannula. The pressure sensor is formed from a stack of coplanar layers including a top layer, a base layer an electrode layer and a counter electrode layer. The fluid channel is positioned between the top layer and the base layer. The electrode layer is positioned between the top layer and the base layer and coupled to the fluid channel. The counter-electrode layer is positioned between the top layer and the electrode layer. A spacer layer having a through cut-out defining an electrode cavity is disposed between the top layer and the base layer such that the electrode layer extends across the electrode cavity.
