Patent number: 11067485Abstract: An automated smear making apparatus used to prepare and smear samples on glass slides. In one embodiment, there is provided a smearing subsystem that generally includes a smear cartridge having: an input reel; at least one roll bar; a take-up reel; and a smearing tape. The smearing tape is initially wound within the input reel and coupled to the take-up reel such that the smearing tape can be drawn from the input reel and into the take-up reel. The smearing tape may include a plurality of perforations formed therein. The smearing tape may then be wrapped around the roll bar such that each of the plurality of perforations forms a blade that extends from the smearing tape to expose a smear surface as the smearing tape is drawn into the take-up reel. Alternatively, the smearing tape may be bent such that an edge of the smearing tape forms a smear surface between two roll bars. A slide transport surface is also provided to move a slide across the smear surface.Type: GrantFiled: August 9, 2018Date of Patent: July 20, 2021Assignee: Abbott LaboratoriesInventors: John Scott Shoffner, Koshy T. Chacko, Roei Solomon

Publication number: 20210131928Abstract: The present disclosure provides methods for carrying out Romanowsky-type stains, specifically Wright-Giemsa and May-Grünwald stains, quickly and efficiently. The methods greatly reduce the overall amount of time required to complete a Wright-Giemsa stain or a May-Grünwald stain of sufficient quality on a biological sample. The subject methods can be applied to both manual and automated staining procedures.Type: ApplicationFiled: November 12, 2020Publication date: May 6, 2021Inventors: Abe S. Mamaghani, Koshy T. Chacko, Rupa Rao, Rene Nieves Alicea

Patent number: 10983305Abstract: Methods, systems and devices for automatically focusing a microscope on a specimen and collecting a focused image of the specimen are provided. Aspects of the methods include detecting the presence of a substrate in a microscope, determining whether the substrate is in a correct orientation for imaging, focusing the microscope on a specimen that is placed on the substrate, and collecting one or more images of the specimen. Systems and devices for carrying out the subject methods are also provided.Type: GrantFiled: July 16, 2019Date of Patent: April 20, 2021Assignee: Abbott LaboratoriesInventors: Trevor David Shields, Robert John Fahey, Damian J. Verdnik, Svitlana Y. Berezhna, Mahmoud Janbakhsh, Koshy T. Chacko
