Abstract
A multiple reagent test strip-reading instrument having rails extending from a loading area to one or more reading station platforms and then to a waste receptacle, a reciprocating blotter arm which contacts individual reagent strips sequentially placed transversely on the rails in the loading area, moving individual strips along the rails to an indexing strip advancing mechanism which intermittently advances the strips along the rails in spaced parallel relation, and after each advance, allows the strips to dwell for a predetermined time period; individual test strips being thereby sequentially delivered to reading position on the reading station platform where, during the dwell period, they are read by reflectance photometry. After reading, the strips are moved to the waste receptacle. Means is provided for insuring that each test strip is delivered to reading position in registration with the read head of the photometer, and means is also provided for pressing each test strip flat against the reading station platform. The indexing mechanism employs a strip advancing member provided with parallel rows of equally spaced upstanding pegs or fingers, there being guiding and drive means for imparting movement to said member along a vertical orbital path having a generally circular extent and also having a rectilinear extent parallel with the rails, said pegs intersecting the plane of the reagent strips on the rails when said member moves forwardly along said rectilinear extent and being withdrawn from said plane when said member moves rearwardly along said circular extent.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
