Thereby, it is possible to provide a biomolecule-immobilized plate having a surface of a high degree of smoothness on which functional groups are produced, a biomolecule-immobilized plate on which biomolecules are immobilized via functional groups, and methods for fabricating these biomolecule-immobilized plates easily and inexpensively.Type: GrantFiled: September 10, 2009Date of Patent: July 26, 2011Assignee: Panasonic CorporationInventors: Jimpei Tabata, Shigeki Joko

Publication number: 20110174708Abstract: A sample stirring device of the present invention includes a driving roller and two follower rollers for coming into contact with a sample container including a cylindrical portion for containing a sample to be stirred. The driving roller is driven for rotation to stir the sample contained in the sample container. The two follower rollers have rotation axes inclined with respect to an axial direction of the cylindrical portion. This arrangement allows the sample container such as a blood collection tube to be rotated stably.Type: ApplicationFiled: October 2, 2009Publication date: July 21, 2011Applicant: ARKRAY, INC.Inventors: Shin-ichi Oota, Hidenari Yamagata, Takeshi Takagi, Koji Egawa

Patent number: 7981382Abstract: A device for collecting, testing and storing fluids includes a container and a removable cap. Body fluids, such as urine, are collected in the container. The cap defines a test strip holder that receives one or more drug test strips and an adulteration strip. An opening defined through a bottom of the cap provides fluid communication between the container and the cap. When tilted, fluid from the container enters the cap through the hole. A variety of plugs may be employed to block the opening and thereby prevent fluid communication between the container and the cap after fluid has entered the cap. The remaining uncontaminated and untested body fluid is stored in the container and thus made available for further confirmation testing. Associated methods for collecting, testing and storing fluids with a single device are also provided. A method of manufacturing the foregoing test device is also provided.Type: GrantFiled: June 14, 2005Date of Patent: July 19, 2011Assignee: Branan Medical CorporationInventors: Raphael C. Wong, Ker-Kong Tung

Patent number: 7972579Abstract: The invention relates to a device for the automatic opening and closing of reaction vessels. It comprises a holding device for the non-rotatable holding of one or more reaction vessels, a gripper for the gripping of a lid for the reaction vessel, wherein the gripper has gripping jaws to take hold of the lid, and a holding arm with a rotating mechanism for rotatable holding of the gripper. The gripping jaws are arranged in such a way that, when the lid is inserted into the area between the gripping jaws, it is held by the latter through frictional contact, and the gripper has no active operating device for opening and closing the gripping jaws.Type: GrantFiled: July 1, 2004Date of Patent: July 5, 2011Assignee: F. Hoffmann-La Roche AGInventor: Wolfgang Brunner

Publication number: 20110127292Abstract: A system for dispensing one or more fluids into wells of a target multi-well plate, a holder and a method thereof are disclosed. The system provides the holder which holds the multi-well plate in a predefined holding position, the plate having a well region provided with wells for accommodating the fluids and an edge region surrounding the well region. The holder includes: a contact area which contacts the edge region to form a sealing zone which air-tightly seals a void formed between the holder and the plate; a supporting face which supports the well region in a planar condition; and a duct which connects to a pump to generate a negative pressure in the void so as to draw the well region onto the supporting face.Type: ApplicationFiled: May 25, 2010Publication date: June 2, 2011Applicant: ROCHE DIAGNOSTICS OPERATIONS, INC.Inventors: Emad Sarofim, Martin Kopp, Claudio Cherubini

Useful specimen transport apparatus with integral capability to allow three dimensional x-ray images
Patent number: 7951345Abstract: The present invention provides new and useful features and mechanisms for the localization and transport of biopsy specimens. The invention having a specimen board, an absorbent material in operative engagement and in coplanar alignment with the specimen board, a compression sheet, radio opaque indicia located within the specimen board, and a flexible connection between the compression sheet and the specimen board, and an attachment device which provides for removable engagement of the specimen board and compression sheet. The apparatus further provides for a clear visualization window and operating instructions. The absorbent material is capable of adjustable movement between a first and second position, providing orthogonal positioning relative to the specimen board. As a result, the apparatus may be used to create three dimensional radiographic images allowing tissue analysis resulting in orthogonal views while maintaining original positional reference points.Type: GrantFiled: May 30, 2008Date of Patent: May 31, 2011Assignee: Lary Research & Development, LLCInventors: Todd P.

Publication number: 20110123416Abstract: A sample vial [24] is disclosed, having a generally tubular body [32]. The vial [24] has a generally round lip [34] defining an opening [36] at the top of the body [32]. The vial [24] has a foot [38] at the base of the body [32], having asymmetric first and second sides [40, 42]. A rack [28] is disclosed for supporting such a sample vial [24]. The rack [28] supports the sample vial [24] in a generally upright position in a single orientation. The rack [28] has an asymmetric recess [50] adapted to receive the asymmetric foot [38] in a single orientation. The rack [28] also has an orientation abutment [82] adapted to interfere with a projecting abutment [46] of a vial [24] to prevent insertion of a vial [24] into the asymmetric recess [50] in an orientation other than the single orientation. The orientation abutment [82] also allows insertion of a vial [24] into the asymmetric recess [50] in the single orientation.Type: ApplicationFiled: June 5, 2009Publication date: May 26, 2011Inventors: Jean-Pierre Giraud, David Chedotal
