Patent number: 11940458Abstract: A measurement tool includes: a measurement tool body including a sample collection unit for collecting a liquid sample by a capillary phenomenon, and a liquid feed channel; and a lid body attachable to and detachable from the measurement tool body. The liquid feed channel includes an upstream side channel and a downstream side channel. A space is defined, into which an upstream side end of the sample collection unit and a downstream side end of the upstream side channel open, when the lid body is attached to the measurement tool body. The downstream side channel is connected to a downstream side end of the sample collection unit. The space is open when the lid body is separated from the measurement tool body, and the space is closed and the upstream side channel and the sample collection unit are connected when the lid body is attached to the measurement tool body.Type: GrantFiled: November 21, 2019Date of Patent: March 26, 2024Assignee: SEKISUI CHEMICAL CO., LTD.Inventors: Tsutomu Nakamura, Kazuhiko Imamura, Nobuhiko Inui, Ryousuke Takahashi
