Microstructured fluid flow control device
A microstructured fluid flow control device includes a substrate with a piezo-actuated first membrane arranged on a first substrate side, and a fluid channel that extends through the substrate between the first substrate side and an opposite second substrate side. In addition, the microstructured fluid flow control device includes a microvalve that extends through the fluid channel and is configured to close the fluid channel in an unactuated state, and a second membrane arranged on the first substrate side and spaced apart from the membrane and arranged between the fluid channel and the first piezo-actuated membrane. The second membrane is joined to the microvalve and is mechanically biased towards the first membrane so that a biasing force is applied to the microvalve, wherein the biasing force is part of a restoring force that causes the microvalve to close the fluid channel in an unactuated state.

APPARATUS, SYSTEM AND METHOD FOR FLUID DELIVERY
A fill adapter system for an infusion pump assembly. The system includes a reusable fill adapter base, the base including a volume control mechanism to adjust an available fill volume of a reservoir of the infusion pump assembly and a pump mechanism configured to pump air into a fluid vial. The system also includes a vial adapter assembly including a first needle configured to penetrate a septum of the fluid vial for fluidly coupling the pump mechanism to the fluid vial and a second needle having a first end configured to penetrate the septum of the fluid vial and a second end configured to penetrate a septum of the reservoir of the infusion pump assembly to allow transfer of fluid from the fluid vial to the reservoir of the infusion pump assembly in response to air being pumped into the fluid vial and a needle carriage adapted to carry the first needle and the second needle, wherein the needle carriage slidably attached to the interior of the vial adapter assembly, wherein the needle carriage adapted to slide from a vial end of the vial adapter to a receptacle end of the vial adapter.
Application device for coating components with a coating agent
An application device for coating components with a coating agent includes: a print head having several individual nozzles for discharging the coating agent; and a nozzle valve attached to each individual nozzle, each nozzle valve being openable for a valve opening time to discharge the coating agent from the respective nozzle. Each nozzle valve is assigned in each case a nozzle valve supply line, which nozzle valve supply line, at an outlet opening thereof, supplies the coating agent to the respective nozzle valve. Each nozzle valve supply line has an inlet opening to be closed or shut off such that a quantity of the coating agent that is metered in a defined manner or a volume of the coating agent that is metered in a defined manner is receivable in a closed off manner within the nozzle valve supply line.
DOSING APPLICATOR FOR MEDICAL AND NON-MEDICAL CONTAINERS
A device for precise dispensing of liquids utilizing pressure-operated valves to control fluid travel. Use of a flexible bulb within a fluid vessel provides manual actuation of the valves through application of pressure to the exterior of the fluid vessel.

Vial With Metered Dispenser
A polymer vial with a tubular body having a geometric shape including (i) a neck having an opening orifice, and (ii) a closed base formed by flattening and sealing a bottom edge of the tubular body. The vial will also include a snap off cap integrally formed on the neck and a liquid content contained in the tubular body. A plurality of dosage lines are printed on the tubular body, the dosage lines having a non-uniform spacing corresponding to the variable volume per unit length of the vial geometric shape. Each line corresponds to a dosage volume of the liquid content when the opening orifice is oriented in the vertically upward position.
Dispensing head and dispensing device for the metered dispensing of liquid preparations, and possible uses
The present invention relates to a dispensing head (1) for a dispensing device, and to a dispensing device (100) for the metered dispensing of liquid preparations, which dispensing device is provided with the dispensing head.
