Appl. No.:

09/663719

Inventors:

Vijay Mathur - Burlington MA
Tyler Cote - Acton MA
Ronald Jones - Newton NH

Assignee:

Medica Corporation - Bedford MA

International Classification:

G01N 100

US Classification:

7386424

Abstract:

A modular automated diagnostic analyzer having a fluid entry module for sample aspiration, a valve module for selecting fluids and a pump module for fluidic movement, so that a biological sample does not come into contact with the valve system through which calibrants and air are introduced to the fluid path. The fluid entry module encloses an aspiration tube rotatably and slidably engaged with the analysis mechanism chassis to move to different positions for the introduction of calibration and cleaning fluids and the aspiration of fluids into the analysis apparatus from different types of sample containers. A wiping seal removes residues of aspirated fluids from the exterior surfaces of the aspiration tube with the residue being aspirated into the analysis apparatus for disposal. Sensor modules mounted in a sensor chamber are structured to mechanically stack and interlock and each sensor module includes a fluid tight sealed passage and a sensor element. A fluid selection valve of highly polished ceramic material allows a valve cylinder passage to be selectively connected to fluid sources.
