HANDHELD ANALYZER FOR TESTING SAMPLE

摘要

PROBLEM TO BE SOLVED: To provide a handheld analyzer for testing a sample for a medically significant component, and a method for causing the handheld analyzer to operate in such a way as to reduce the possibility of malfunctions or operating errors. SOLUTION: This analyzer comprises a test unit 20 which detects the correct positioning of analytical consumable means 10 in a conveyance pathway. The test unit has both an electric switch 21 which mechanically senses the positioning of the analytical consumable means and an optical sensor 30 which optically senses the positioning of the analytical consumable means 10 on the conveyance pathway. The handheld analyzer 1 is controlled as a result of a comparison of the signals of the electric switch and the optical sensor. Employing this method reduces malfunctions or operating errors associated therewith. COPYRIGHT: (C)2009,JPO&INPIT
