Reagent reservoir and magnetic stirring system
Abstract
Abstract A TESTING APPARATUS FOR AUTOMATICALLY DETERMINING PROTHROMBIN TIMES AND OTHER SIMILAR FACTOR ASSAYS. A TURNTABLE CONVEYOR MOVES SUCCESSIVE BLOOD PLASMA SAMPLES IN CONTAINERS TO A TEST STATION WHERE EACH SAMPLE IS TESTED, PERTINENT INFORMATION SENSED AND FED TO A PRINTER FOR READOUT. PRELIMINARY TO THE TESTING STATION IS A FIRST REAGENT DISPENSER WHERE A REAGENT IS DISPENSED TO EACH SAMPLE AND A SECOND REAGENT DISPENSER IS LOCATED AT THE TESTING STATION FOR ADDING A SECOND REAGENT. INTERMEDIATE THE TWO REAGENT DISPENSERS IS A SAMPLE INCUBATION DEVICE WHICH INTIMATELY CONTACTS EACH CONTAINER TO APPLY HEAT THERETO TO INCUBATE THE SAMPLE CONTAINER THEREIN. EACH REAGENT DISPENSER IS PROVIDED WITH A REAGENT RESERVOIR AND ASSOCIATED MAGNETIC STIRRING SYSTEM. A UNIQUE SYSTEM FOR DECOUPLING THE MAGNETIC STIRRING SYSTEM FROM A MAGNETIC STIRRER AND MOVING THE MAGNETIC SITTER OUT OF THE PATH OF A PIPETTE FORMING PART OF EACH REAGENT DISPENSER IS PROVIDED. AT THE TESTING STATION, A UNIQUE PHOTOSENSITIVE DETECTION DEVICE IS PROVIDED FOR SENSING THE FORMATION OF CLOTS AFTER THE SECOND REAGENT IS ADDED.
