CARTRIDGE ARRANGEMENT, FLUID ANALYZER ARRANGEMENT, AND METHODS

摘要

A cartridge for analysis of fluid samples useable with an analyzer device includes an arrangement to selectively control fluid flow within the cartridge. One type of cartridge includes a fluid channel. A sensor arrangement is oriented within the fluid channel and includes at least one dry-stored sensor and at least one wet-stored sensor. The cartridge may include a first port. In some instances, the cartridge can include a second port. In some instances, the cartridge can include a third port. In some implementations, a cartridge includes a fluid reservoir in fluid communication with a port on the cartridge. The fluid reservoir defines a fluid passage and a fluid dispenser actuator. The actuator includes an over-center engageable button depressible to initiate fluid flow from an internal volume in the fluid reservoir and through the fluid passage and through the port into the sensor arrangement on the cartridge. Methods for analyzing, calibrating, and using the cartridge are provided.
