Abstract: A disposable diagnostic device (10) includes a body (12) having a first channel (14) and a second channel (16) spaced from the first channel. A blister (18) is operably fixed to the body and encloses a chamber (20) which is configured in a hermetically sealed-off relation from the first and second channels when the device is in a non-activated first state and is in open communication with at least one of the first and second channels when the device is in an activated second state. A reactant (22) and an inert gas (24) are disposed in the chamber such that the inert gas protects the reactant from being exposed to contaminants when the device is in said non-activated first state. A method of constructing a disposable diagnostic device is also disclosed.

Abstract: A blister actuator assembly (12) for actuating a blister assembly (14) of a diagnostic cartridge assembly and dispensing fluid from the blister assembly is provided. The blister actuator assembly includes an articulated actuator having a drive body (24) and a plurality of driven links (28). The drive body is configured to translate generally along a first axis (26) from a non-deployed position to a deployed position upon being acted on by an actuation force directed generally along the first axis. The driven links extend in inclined relation from the drive body, with the driven links being configured to pivot relative to the drive body into forcible engagement with the blister assembly to dispense fluid from the blister assembly in response to the drive body translating along the first axis.
