A two-component fluid dispenser which can accurately mix two liquids of varying viscosity and then precisely deliver the mixture formed in discrete amounts. The mixture of the two components is delivered from a single delivery tube in a manner such that none of the mixture remains within the delivery tube at the completion of each mixing and delivery cycle. In one form of the apparatus, the single delivery tube of the apparatus is operably coupled with conventional hypodermic syringes of various sizes so that different fluids can be mixed in different ratios.

A pump system for an infusion system includes a linear drive (36, 36′) which minimizes the space occupied by the pump components in a portable housing (10, 10′). A motor (34) and a motor drive shaft (42) are arranged in parallel with, and adjacent to a syringe (14, 14′) and lead screw (94, 94′). A gear box (54) connects the drive shaft and lead screw to transfer rotational movements between them. A piston driving member, such as a cone (116) or drive nut (116′) converts the rotational movement of the lead screw into linear motion of a syringe piston (24). Sensors (150, 152) detect when the piston or cone is in a “home” position and in an “end” position, respectively. Optionally, a proximity sensor (170) is used to ensure that the cone and the piston (24) are abutting during dispensing. Alternatively, a clamping member (350) selectively clamps the lead screw (94′) against linear motion in at least a dispensing direction.

Accordingly, the temperature under the substrate can be maintained constant, and generation of parasitic plasma or contaminating particles can be avoided.

Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container. Some embodiments of the device can include a motor and a controller for automatically actuating a plunger of the syringe to transfer the desired amount of fluid.

A cartridge connectable to a fuel cell is disclosed. The cartridge comprises an outer casing and an inner flexible liner containing fuel for the fuel cell.

The cartridge is also adaptable to receive byproducts from the fuel cell. The cartridge can also be pressurized to push fuel to the fuel cell. Unidirectional relief valves are also disclosed to prevent internal pressure in the cartridge from becoming too high or too low.
