Patent number: 11511246Abstract: The present invention provides a cartridge, a detection method, and a detection device capable of stabilizing the liquid level of a sample accommodated in a chamber in a predetermined state. A cartridge 20, that is rotated around a rotating shaft 42 for detecting a target substance, is provided with a chamber 100 in which a sample containing a target substance is stored. The chamber 100 includes a first region 110 in which a sample is stored, a second region 120 disposed at a position closer to the rotating shaft 42 than the first region 110, and a protrusion 130 protruding from a position between the first region 110 and the second region 120 to the inner side of the chamber 100.Type: GrantFiled: September 27, 2018Date of Patent: November 29, 2022Assignee: SYSMEX CORPORATIONInventors: Yongjian Yang, Tomoyuki Nose, Sayuri Tomoda, Kazuyoshi Horii
