The machine includes a hinged arm to which a clamp for gripping a first biological sample holder is fixed. The clamp includes first and second arms able to move relative to each other along a gripping position between a first position of gripping the first biological sample holder, and a first position of releasing the biological sample holder. Each arm of the clamp includes a groove. When the first and second arms are in the first position of release, the first and second grooves are spaced away from each other along the gripping direction, and when the first and second arms are in the first gripping position, the first and second grooves are brought closer to each other along the gripping direction, so as to be able to receive lateral edges of and grip the first biological sample holder.Type: GrantFiled: June 5, 2009Date of Patent: December 30, 2014Assignee: Noviloire SAInventors: Michel Philippon, Sébastien Bernay

Patent number: 8916113Abstract: An automatic chemical analyzer in which a reaction solution is stirred by air ejected from an air ejection hole placed above a reaction container. The reaction region can be washed and cleaned sufficiently without causing damage, such as exfoliation of a coating reagent. A reaction container disk 161 is provided with a pore 240 and a pressure detector 241 connected with the pore. Before and after the stirring operation, the ejection hole (nozzle) 170 ejecting air is moved and the output value of the pressure detector is compared with a previously measured normal value. With a discharge pipe 1101 and a suction pipe 1102 inserted to the opening of the reaction container 1140 to be close to both ends of the opening and the side wall of the container, the reaction region 1150 at the bottom of the container is washed by continuous discharge and suction of cleaning fluid.Type: GrantFiled: February 22, 2010Date of Patent: December 23, 2014Assignees: Hitachi High-Technologies Corporation, Roche Diagnostics Operations, Inc.Inventors: Hironobu Yamakawa, Yoichi Aruga, Takenori Okusa, Kenichi Takahashi, Hans Hornauer, Hans-Juergen Mueller

Patent number: 8906326Abstract: A biochemical reaction cassette having a structure for uniformizing a liquid flow in a reaction chamber with a simple additional arrangement is provided. A fluid resistive section is arranged in a channel that is constructed to include an injection port, a reaction chamber, and a discharge port. The fluid resistive section decreases the cross-sectional area of the channel to decrease the fluid resistance at ends in the width direction of the fluid resistive section and at positions remote from the injection port and the discharge port, where the flow rate is decreased.Type: GrantFiled: December 20, 2007Date of Patent: December 9, 2014Assignee: Canon Kabushiki KaishaInventors: Takaaki Aoyagi, Tomoyuki Makihira

Publication number: 20140356234Abstract: Improvements in and relating to devices for receiving liquid samples A device for receiving a liquid sample may form part of a micro sampling head for an instrument such as a spectrophotometer. The device receives a liquid sample to be analysed by a process involving the passing of electromagnetic radiation through the sample, and comprises a light inlet guide (20) for directing electromagnetic radiation into the sample, a light receiving element (23) situated in an opposed relationship to the guide and spaced from the guide by a fixed distance to define a fixed path length gap (21), which is, in use, filled with the sample. In use, radiation is passed from the light inlet guide to the light receiving element (23), and the path length of radiation through the sample is defined by the gap (23). The device is open or openable to allow a droplet of sample to be deposited directly in the gap.Type: ApplicationFiled: November 8, 2012Publication date: December 4, 2014Inventor: Graham Eric Gifford

Patent number: 8900514Abstract: The invention discloses a blood analyzing device (100) comprising a holder (110) arranged for carrying a container (10) having a cuvette (20) containing a blood sample (30). The container (10) is positioned in the holder (110) so that a longitudinal axis (60) of the cuvette (20) is angled relative a horizontal axis (70). A light source (120) provides light (40) into the sample (30) and a detector (130) detects the output light (50) from a sub-portion of the blood sample (30). Kinetic information indicative of the change in hemoglobin concentration in a measuring volume (32, 34) is determined by a Hb processor (145) from the detected output light (50). An ESR processor (140) determines the erythrocyte sedimentation rate of the sample (30) based on the kinetic information.Type: GrantFiled: September 1, 2008Date of Patent: December 2, 2014Inventor: Tommy Forsell
