Diagnostics testing devices and processes
First Claim
1. A diagnostic device having a first chamber for receiving a sample and a multiplicity of separate analysis chambers in controlled communication only with the first chamber, wherein the improvement comprises the combination of:
- (a) at least one diagnostically useful substance predispensed in solid form to each of the individually viewable, optically transparent analysis chambers;
(b) optically transparent and flat cover seal means being disposed above each of the analysis chambers to render each analysis chamber individually viewable in a vertical orientation from above said analysis chamber;
(c) self-contained means for controlling communication between the first source chamber and the optically transparent analysis chambers, and for dispensing sample from the first chamber simultaneously and in uniform amount to each of the analysis chambers concurrently with venting said first chamber said means being adjustably interdisposed between said first chamber and said analysis chambers; and
(d) analysis chambers circumferentially arranged relative to the first chamber, each of said analysis chambers sharing in common a wall with the immediately adjacent analysis chambers.

Abstract
A convenient, self-contained, disposable device suitable for the rapid identification of microorganisms, having capability for simultaneously carrying out a multiplicity of analytical determinations. The device comprises a disc-shaped arrangement defining a multiplicity of satellite testing chambers each of which is connected to a centrally defined chamber. The central chamber is provided with a movable sleeve or piston arrangement. Liquid sample is received in the central chamber and the sleeve is manipulated to provide samples uniformly and simultaneously to each of the satellite testing chambers without resorting to external means, such as positive or a negative pressurization or centrifugal force. Also disclosed are unique disc-shaped optically transparent support films which are coated on one or both sides with analytical substrates or reagents which are predispensed to the satellite testing chambers.

31. Diagnostic method comprising:
-
(a) predepositing in solid form at least one selected substance useful in the identification of at least a part of a sample, into each of a series of separate, optically transparent analysis chambers; (b) depositing a sample in a single source chamber; (c) providing a portion of said sample simultaneously to each of the separate analysis chambers and while maintaining the orientation of the device concurrently venting said source chamber, such that a substantially uniform amount of sample is received therein; and (d) individually measuring the nature and extent of reactions between the sample portion and substance useful in its identification in each optically transparent, separate analysis chamber whereby the nature and extent of said reactions are indicative of identifying characteristics of said sample. - View Dependent Claims (32, 33)
