Publication number: 20230143259Abstract: According to one embodiment, an automatic analyzing apparatus includes a feeder and a mixer unit. The feeder is configured to feed a first liquid and a second liquid. The mixer unit includes an inflow part, an internal space, and an outflow part. The mixer unit is configured so that the first liquid and the second liquid fed from the feeder enter through the inflow part, the first liquid and the second liquid entering through the inflow part flow inside the internal space, and the first liquid and the second liquid flowing inside the internal space exit through the outflow part according to an inflow entering through the inflow part.Type: ApplicationFiled: November 10, 2022Publication date: May 11, 2023Applicant: Canon Medical Systems CorporationInventors: Tomohiro SUGIMURA, Shozo HASHIMOTO, Takashi GOTO, Masahiro MASUBUCHI, Yasuo AKIZAWA

Publication number: 20220308079Abstract: An automatic analyzing device according to an embodiment of the present disclosure includes a reagent cartridge and processing circuitry. The reagent cartridge includes a storing unit storing therein a reagent, a flow path for dispensing the reagent from the storing unit, and a dispensing mechanism configured to dispense the reagent into a reaction cuvette through the flow path. The processing circuitry is configured to control the dispensing mechanism so as to dispose of the reagent in the flow path.Type: ApplicationFiled: March 21, 2022Publication date: September 29, 2022Applicant: CANON MEDICAL SYSTEMS CORPORATIONInventors: Shozo HASHIMOTO, Tomohiro SUGIMURA, Masahiro MASUBUCHI, Takashi GOTO, Yasuo AKIZAWA

Publication number: 20220203352Abstract: A reaction cuvette according to an embodiment is used for measurement performed by an automatic analyzing device, and is a reaction cuvette that houses a mixed liquid of a reagent and a sample to be measured. The reaction cuvette includes a cuvette main body and an aspiration port. The aspiration port is disposed on the cuvette main body, and allows a fluid to flow into an inner part of the cuvette main body from a bottom surface side of the cuvette main body.Type: ApplicationFiled: December 27, 2021Publication date: June 30, 2022Applicant: CANON MEDICAL SYSTEMS CORPORATIONInventors: Shozo HASHIMOTO, Masahiro MASUBUCHI, Takashi GOTO, Tomohiro SUGIMURA, Yasuo AKIZAWA

Patent number: 10215770Abstract: According to one embodiment, an automatic analyzer includes dispenser, measurer, thermostat, cooler and cleaner. Dispenser dispenses a specimen and a reagent into a reaction vessel. Measurer measures a solution mixture of the specimen and the reagent in the vessel. Thermostat heats the mixture to a first temperature at which thermoresponsive polymers contained in the reagent aggregate. Cooler cools a cleaning fluid used to clean the vessel to a second temperature lower than the first temperature, at which the polymers contained in the reagent disperse. Cleaner cleans the vessel from which the mixture has been drained, using the cooled fluid.Type: GrantFiled: September 12, 2017Date of Patent: February 26, 2019Assignee: Toshiba Medical Systems CorporationInventors: Michiaki Takeuchi, Tomomi Muramatsu, Masahiro Masubuchi, Satoshi Matsumoto
