Patent number: 9970948Abstract: If an air bubble is entrained when a reagent is added to a sample, disturbance caused by this air bubble may prevent accurate optical measurement, thereby reducing accuracy for measuring blood clotting ability. The position to dispense the reagent depends on accuracy of stopping a reagent dispensing mechanism and dimensional errors of individual detectors, and thus conventional reagent discharging method may entrain an air bubble because a distance between a nozzle for dispensing the reagent and an inner wall of a reaction vessel is not constant and conditions for dispensing the reagent to the sample vary. In the present invention, an automatic analyzer with a nozzle for sucking and discharging the reagent for blood clotting reaction is provided with a dispensing mechanism that keeps a constant position for the nozzle to discharge the reagent by pressing the nozzle against the inner wall of the reaction vessel within the elastic range.Type: GrantFiled: October 22, 2014Date of Patent: May 15, 2018Assignee: Hitachi High-Technologies CorporationInventors: Toshiyuki Shimamori, Akihisa Makino, Masato Ishizawa
