Hand held dispenser

A container closure device for facilitating withdrawal of a liquid from a collapsible sealed packet is disclosed. The device includes a needle guide and a septum retainer wherein the needle guide is fixable to an outer face of the packet and the septum retainer is fixable to an inner face of the packet in alignment with the needle guide. The needle guide includes a tube for receiving a needle and insures proper alignment of the needle. The septum retainer includes a septum chamber having a septum disposed therein.

Drug containment system

A micropump comprising a pump body including a fluid inlet channel, a fluid outlet channel and pumping reservoir, the fluid inlet channel and the fluid outlet channel communicating with the pumping reservoir, a diaphragm covering the pumping reservoir, a piezoelectric strip actuator attached to the diaphragm such that by applying a voltage to the actuator, the diaphragm can be raised or lowered relative to the pumping chamber, a valve on the inlet channel and the outlet channel, the valve opening and closing the inlet and the outlet channel in response to the raising and lowering of the diaphragm.

Piezoelectric micropump with diaphragm and valves

A multi-channel valve having a valve seat, a valve seal, and valve seal housing. The assembly of the apparatus creates a plurality of inlet, exit, and cross channels enclosed by elastomeric portions of a valve seal. The elastomeric portions of the valve seal create bounded distensible chambers. Pressure exerted by a fluid in excess of the cracking pressure of the seal tends to distend portions of the elastomeric seal and allow flow through and into the chambers. When inflow pressure falls, the elastic rebound of the elastomeric portions of the seal tends to expel fluid from the valve without backflow. Cross channel capacity allows mixing of the fluids. The plurality of, and differentials between, chambers allows one fluid to completely purge the valve of other fluids. The valve may be configured with additional backflow prevention capacities, such as channel variations, secondary elastomeric members, and variations in primary membrane properties.
