Abstract: A fitment device may include a core made of a first material and including a securing portion configured to secure to a chassis and a container portion configured to seal to a container. The fitment device includes an aperture including a first end located at the securing portion and a second end located at the container portion, wherein the aperture is configured to receive a probe in the first end. A plug located in the aperture is movable within the aperture upon contact with the probe to open a passageway between the first end and an interior of the container. Other devices and methods are disclosed.

Abstract: A fitment device may include a core formed from a first material having a first low permeability of oxygen. The core may include a securing portion configured to secure to a chassis, and a container portion including at least one side portion at least partially coated with a second material configured to seal to a container, wherein the first material is different than the second material and includes a different gas permeability of oxygen. An aperture may extend between the securing portion and the container portion. Reagent cartridges and methods of manufacturing and using fitment devices are also disclosed.

Abstract: A sensor assembly includes a first sensor substrate with upper surface, lower surface opposite upper surface, and a first set of sensors on the first sensor substrate. The sensor assembly includes a second sensor substrate with upper surface, lower surface in opposite upper surface, and a second set of sensors on the second sensor substrate. The sensor assembly includes a base with upper surface, lower surface opposite upper surface of the base along a vertical direction, a front end, a rear end opposite the front end along a longitudinal direction perpendicular to the vertical direction, a first recess at least partially holds the first sensor substrate, a second recess at least partially holds the second sensor substrate, a first fluid passage for receiving a fluid, and a second fluid passage in series with and open to the first fluid passage. Both sensors are exposed to its corresponding fluid passage.

Abstract: Improved analyte detection system within a blood gas analyzer, the improved system comprising and/or consisting of at least one CO-oximetry system that is formed as an integrated, unitary structure(s) with an electrochemical sensor module, and methods of use related thereto.

Abstract: A sensor assembly for analysis of physical parameters and chemical constituents of small volume samples of bodily fluids. Disclosed herein is a sensor panel with an upper surface and a lower surface and at least one analyte sensor located on the lower surface. The sensor assembly also includes an optional adhesive layer and a contoured fluid pathway cutout. The upper surface of the adhesive layer is secured to the lower surface of the sensor panel. The sensor assembly also includes a sensor cartridge base with a fluid inlet and outlet and a contoured fluid pathway extending between the inlet and the outlet. The contoured fluid pathway mirrors the shape and span of the contoured fluid pathway cutout of the adhesive layer. As a fluid sample is input at the fluid inlet, the fluid traverses along the fluid pathway in contact with the at least one analyte sensor.
