US Patent:

20080261324, Oct 23, 2008

Filed:

Nov 16, 2006

Appl. No.:

12/092277

Inventors:

William Carpenter - Stony Point NY, US
Martin Fletcher - Hopewell Junction NY, US

Assignee:

Siemens Healthcare Diagnostics Inc. - Tarrytown NY

International Classification:

G01N 21/76
B01L 3/02

US Classification:

436172, 422100, 422 52

Abstract:

Devices, systems, and methods for conducting chemiluminescent immunoassay testing and, more particularly, to initiating and monitoring a chemiluminescent reaction in a plurality of such assays, of different types, on a single immunoassay instrument, in a single procedure, using a plurality of labels and a triggering reagent combination are disclosed. Moreover, by including a base reagent injector assembly having an “e-channel” to provide a swirling turbulence to the base reagent immediately before it is introduced into the well of a cuvette containing a sample and an acid reagent. The added turbulence addresses the phenomenon referred to as “RLU shift,” in which the luminescence output can increase or decrease between assays.

G01N 35/00

Abstract:

An environmental control system for use in a clinical analyzer module includes an upper deck environmental subsystem comprising a far field sensor, one or more heaters, one or more spine cooling fans, and one or more in-line fluid heat exchangers. The far field sensor is configured to acquire measurements of ambient temperature in the upper deck environmental subsystem. The heaters are configured to generate hot airflow based on the measurements of ambient temperature from the far field sensor. The spine cooling fans are configured to operate in a manner that mixes the hot airflow from the heaters with cool airflow based on the measurements of ambient temperature from the far field sensor. The in-line fluid heat exchangers are configured to heat fluids used in reactions performed on the clinical analyzer module to a constant temperature.
