Electrode unit and package for a blood analyzer
First Claim
1. An electrode unit for use in a package of a liquid analyzer machine for analyzing blood or other liquids and the like, comprisinga cylindrical outer housing having outer and inner surfaces and open ends with end edges,a pair of top hat end bushings each having a central bore and having a plug portion, with a cylindrical surface and an inner end face, and an end flange portion with an outer end face,one of said bushings being positioned in each end of the outer housing with the plug portion of the bushing extending inside the housing and the flange of the bushing abutting against end edges of the outer housing, with the plug inner end faces forming a filling chamber with the inner surface of the housing,said bushing outer end faces being flat to fit flush against the flat outer end faces of the bushings of adjacent units,a filling solution inside the chamber,a silver-silver chloride electrode mounted on and extending through the outer housing into the solution in the chamber,a sodium glass capillary tube mounted in the bores of the bushings concentric with the outer housing and extending between the bushings through the solution in the chamber to the outer end faces of the bushings,adhesive means sealing the sodium tube to the bushings and sealing the bushings to the outer housing,said tube being adapted to contain a liquid sample to be analyzed,an annular groove formed in the flat outer end face of each bushing flange,an alignment ring for seating in the bushing annular grooves of two adjacent electrode units to center the electrode units, andthe height of the alignment ring being smaller than the combined depths of two annular grooves of the bushings so that the outer faces of adjacent bushing flanges may be pressed against each other to form a tight connection and avoid leakage of the liquid sample passing between adjacent electrode units.

Abstract
An electrode unit for use in an analyzer of blood and of liquids includes a cylindrical outer housing having open ends and a pair of top hat end plate bushings each having a central bore and a plug portion, the bushings being positioned in each end of the housing with the plug portion directed into the housing to form a filling chamber with the inner surface of the housing. A sodium glass capillary tube is mounted in the bores of the bushings. An annular groove is formed in an end flange portion of each bushing so that a connecting alignment ring may seat in the bushing annular grooves of two adjacent electrode units to center the electrode units.
