Metering device for powder and method for metering powder

A metering device for the volumetric metering of powder, including pharmaceutical powder, and the simultaneous metering and filling of target cavities with metered powder, as well as a metering system and an associated method are shown. One embodiment of the metering device includes a metering station with a powder storage container, a filling station, and a movable metering member. The metering member has a flat transfer surface that includes metering cavities, which correspond in number and geometry to target cavities arranged in the filling station, and also to metering openings in the metering station. The metering cavities each have an open end and a base, wherein an air-permeable filter element forms at least a part of the base of each. The metering member includes a central pressure channel connected to the metering cavities through the filter elements for applying a negative or positive pressure to the metering cavities.

Humidifier reservoir

A reservoir configured to retain a volume of liquid for use in an apparatus for humidifying a flow of pressurised air comprises a base portion and a lid portion. The reservoir may be configured to improve its level of thermal contact to the heater plate using the flow of pressurised air. The reservoir may be configured to improve thermal contact between the reservoir and the heater plate by pre-compression upon engagement of the reservoir with the humidifier. The reservoir may comprise a removable intermediate portion, which may include the inlet tube and/or the outlet tube, for improved access for cleaning. The reservoir may also be configured to prevent overfilling. Overfill prevention features in the reservoir may include defined flow egress paths and/or formation of air locks.

Adhesive and peripheral systems and methods for medical devices

Fill stations and base stations are provided for personal pump systems. The fill stations may be opened and closed to accept a reservoir and to allow fluid to be introduced into the reservoir for use with personal pump systems. The fill stations may hold the reservoir at a tilt relative to an underlying surface and may discourage overfilling of the reservoir. The filling stations may also include viewing windows having fluid lines marked thereon for indicating volume of fluid within the reservoir.

A method for filling and closing pharmaceutical objects disposed in parallel rows in nests includes removing the objects from the nests at an inlet of a conveying device in a removal station and placing the objects into the conveying device. In the conveying device, the objects are fed in succession to a first weighing station and weighed, to filling station and filled and to a second weighing station and again weighed and to a closing station and/or crimping station and closed. After closing, the objects are removed from the conveying section. In every case, pre-sterilized objects are processed in an aseptic manner.

Robotized syringe actuator

A robotized syringe actuator has a holding clamp for holding the peripheral flange of the opening of the tube or the flange at the end of the syringe plunger, by applying simultaneous pressure to both faces of the tube flange or of the syringe plunger flange. The actuator has a holder for the syringe cylinder which has a housing for receiving the syringe tube.

Compliant coupling assembly for cartridge coupling of a drug delivery device

An assembly for coupling a drug delivery device to a cartridge is disclosed. Optionally the assembly includes a coupling, for example a cannula, having one end extending toward the cartridge. The cartridge is optionally aligned by a guide. Optionally the cartridge has a limited freedom of movement. The coupling is optionally supported by a mount. In some embodiments, the mount is compliant enough that the end of the coupling that extends toward may move to said limited freedom of movement under a force less than a leak threshold of the connection between the coupler and the cartridge.
