Patent number: 10768186Abstract: In medical analysis devices and automatic specimen examination systems, the specimen conveyance mechanism is constituted by a plurality of belt lines. During installation or maintenance of the specimen conveyance mechanism, it is necessary to confirm the existence of steps at the joints of these belt lines and the parallelism of the conveyance line. According to the present invention, it is possible to lighten the burden of this work with a test tube type or conveyance holder type inspection device provided with a sensor and battery for operation. Also, even when an operator cannot visually confirm the conveyance line from outside, it is possible to confirm the state of the conveyance line.Type: GrantFiled: February 1, 2016Date of Patent: September 8, 2020Assignee: Hitachi High-Tech CorporationInventors: Eiji Takaya, Hideo Enoki, Shigeki Yamaguchi, Koichi Obari, Yoshiaki Shishido, Masahito Kakuno

Patent number: 10604393Abstract: A device for unstopping a stopped specimen vessel that contains a liquid specimen such as blood is equipped with a mechanism which sucks and captures particles floating around the opening of the specimen vessel and prevents contamination of the specimen. The unstopping device grips a vessel and the stopper of the opening of the vessel, and removes the stopper from the opening of the vessel by changing the relative distance between the vessel-gripping mechanism and the unstopping mechanism. The unstopping device is equipped with: suction holes for sucking therethrough the gas which is present around the opening and contains liquid or solid particles; a pipeline which is connected to the suction holes and through which the sucked gas and particles are led downstream; a suction device connected to the pipeline; and a spirally flexed pipeline part disposed between the pipeline and the suction device.Type: GrantFiled: June 29, 2015Date of Patent: March 31, 2020Assignee: Hitachi High-Technologies CorporationInventors: Hideo Enoki, Shigeki Yamaguchi, Takahiro Sasaki, Tooru Inaba

Patent number: 7922885Abstract: In a device for transporting liquid, liquid to be transported is enclosed by an oil droplet, which is fractionated with air, for manipulation. Moreover, as a method for supplying liquids wherein a plurality of liquids are enclosed by an oil droplet sequentially and treated, liquid enclosed by an oil droplet is formed by associating one oil with one liquid in a liquid introducing section. According to the present invention, even in the case where a plurality of liquids are manipulated, it is possible to manipulate stably without affecting other liquids. Moreover, it is possible to treat as a liquid enclosed by an oil droplet successively in the device for transporting liquid, thereby allowing the invention to be applied to a system for analyzing easily.Type: GrantFiled: May 10, 2006Date of Patent: April 12, 2011Assignee: Hitachi High-Technologies CorporationInventors: Sakuichiro Adachi, Kunio Harada, Hideo Enoki, Isao Yamazaki

Patent number: 7767147Abstract: Conventional liquid transport substrates having a fluid channel formed along an array of electrodes have a problem in which throughput decreases, depending on driving conditions. In order to avoid two-way passage in a fluid channel from the inlet to a measuring section and a fluid channel from the measuring section to the outlet, the measuring section is located in the middle of the fluid channel connecting the inlet and the outlet, so that manipulation from the inlet to the outlet takes place in one direction on the substrate. Even when analyzing a large number of sample droplets, by transport of the droplets substantially in one direction, it is possible to complete measurement in a short time.Type: GrantFiled: October 26, 2005Date of Patent: August 3, 2010Assignee: Hitachi High-Technologies CorporationInventors: Sakuichiro Adachi, Kunio Harada, Hideo Enoki, Hironobu Yamakawa, Tomonori Mimura

Patent number: 7342662Abstract: The adverse effect on measurement accuracy brought about by the transmission of light beams through portions of a liquid sample with different concentrations, i.e., a concentration distribution in the vertical direction of a container, is prevented by using semiconductor light sources of two different types with different wavelengths. The semiconductor light sources (2, 4) of two different types are housed in the same package (5) such that a detector (9) can capture the light beams emitted by the light sources after their optical axes have intersected with one another. The multiple light beams can be thus caused to pass through portions with substantially the same concentration and therefore can be detected without being influenced by the difference in concentration of the sample in the container.Type: GrantFiled: May 19, 2005Date of Patent: March 11, 2008Assignee: Hitachi High-Technologies CorporationInventors: Kunio Harada, Sakuichiro Adachi, Hideo Enoki, Hironobu Yamakawa, Tomonori Mimura
