US 5,629,207 A · Method of controlling test films in biochemical analysis apparatus

Abstract

In a biochemical analysis apparatus a frameless dry chemical analysis film having a reagent layer formed on a support sheet is taken out from a cartridge storing therein a plurality of the frameless chemical analysis films, applied with a sample liquid, inserted into an incubator and taken out from the incubator and at least a part of these steps and film transferring steps between these steps is effected with the film held by a suction pad. A change of pressure in the suction pad when it attracts the film under a suction force is measured and the attracting state of the suction pad is judged on the basis of the result of the measurement. The part of the steps which is effected with the film held by the suction pad is controlled on the basis of the judgment.

Dependent claims

A method of controlling a biochemical analysis apparatus comprising the steps of:

moving an analysis film between a plurality of processing stations, and temporarily holding said analysis film at said processing stations,
wherein at least two of said moving and holding steps are performed using at least two of a plurality of independent suction means,
measuring a pressure in said independent suction means at least two predetermined times after said independent suction means begins attracting said film under a suction force,
judging an attracting state of said independent suction means on the basis of the result of the measurements and a predetermined set of attracting state parameters wherein said attracting state parameters are used to indicate at least two different abnormal states,
and controlling said moving and holding steps on the basis of the judgment.
