Abstract:
The systems and methods disclosed herein permit automated preparation of biological specimens for examination. The disclosed systems and methods provide fast, efficient, and highly uniform specimen processing using minimal quantities of fluids. The methods include at least a fixing phase for fixing a biological specimen to a substrate such as a microscope slide, a staining phase for staining the specimen, and a rinsing phase for rinsing the specimen. One or more of the fixing, staining, and rinsing phases include one or more agitation cycles for distributing reagents evenly and uniformly across the specimen. The systems can be implemented as a standalone device or as a component in a larger system for preparing and examining biological specimens.
Abstract:
A device (1) for handling slides (2), and/or cassettes (3), for specimens of biological material is described and comprises at least one supporting container (10) in which a plurality of cassettes or slides are inserted and supported in at least one rest position in which the cassettes, or slides, are arranged in succession, preferably in a plurality of spaces (S). The container (10) comprises guide means (15) for the insertion and support, in its inside, of at least one slide or cassette. The device further comprises displacing means (8) to displace at least one slide (2), or at least one cassette (3), from the rest position towards at least one operative position, while holding the slide, or cassette, inside the container (10). A method for handling slides and/or cassettes is further described.
Abstract:
Provided are an automatic tissue staining device and an automatic tissue staining method capable of advancing treatments according to precise treatment times without a hitch. The automatic tissue staining device includes a supply head that supplies a treatment fluid, a horizontal direction movement unit that moves the supply head in a horizontal direction, and a holding unit that holds a plurality of glass slides on which samples are set. The automatic tissue staining device further includes a control unit that judges occupancy status of the horizontal direction movement unit in a condition that one or more of the glass slides are situated in a first region prior to supplying the treatment fluid from the supply head to one or more samples on the one or more glass slides situated in the first region, suspends a start of a treatment for the samples on the one or more glass slides situated in the first region when the horizontal direction movement unit is occupied, and permits the treatment for the samples on the one or more glass slides situated in the first region when the horizontal direction movement unit is not occupied.
Abstract:
Methods and compositions for removing precipitates or reducing the formation of precipitates generated in hematoxylin solutions. The methods and compositions feature cleaning solutions that feature chemical compounds that initiate processes including but not limited to acidification of the waste solution, chelation of metal ions in the waste solution, reduction reactions, oxidation reactions, and metal salt addition reactions.
Abstract:
Systems and methods that enable automated spray deposition of biological specimens carried on microscope slides are described herein. Aspects of the technology are directed, for example, to automated specimen deposition systems and methods of generating high-quality, reproducible specimen-bearing microscope slides in automated processing systems.
Abstract:
A smear transporting apparatus transports a smear slide on which a sample is smeared to a smear-image capture apparatus. The smear transporting apparatus includes a smear-container transport part that transports a first smear container accommodating smear slides to a smear pickup position; a smear transfer part that picks a smear slide whose image is to be captured by the smear-image capture apparatus from the first smear container transported to the smear pickup position, transfers the smear slide to the smear-image capture apparatus, and places the smear slide whose image has been captured by the smear-image capture apparatus in a second smear container different from the first smear container; and a storage that stores the first smear container the second smear container.

Abstract:
Methods, devices, and systems for integrating extraction and purification of bio-sample regions and materials with patient analysis, diagnosis, follow up, and treatment. The invention provides a means to insert disclosed substrates, cartridges, and cartridge-processing instrument or instruments into a standard clinic or pathology laboratory workflow. Specifically, we disclose methods, devices, and systems for inserting standard pathology slides into disclosed cartridges and cartridge-processing instruments, either manually, semi-automatically, automatically, or by robotic means.
Abstract:
The disclosure presents systems and methods for processing a specimen slide using a specimen processing system. Specimen slides may sequentially be ejected from a slide carrier towards a label reader to determine an appropriate processing protocol for the slides. A cracking element may be engaged with the slide carrier prior to ejecting the slide, in order to break or “crack” any residual adhesive bond between edges of a slide and walls of the carrier. The specimen slides may be horizontally aligned and resting on a corresponding plurality of flat shelves, enabling even spacing via gravitational forces. The slides are therefore evenly spaced, enabling damage-free ejection of slides, and proper positioning for additional operations including scanning, viewing, heating, washing, and other processing. The label reader may process scanned information from the label of the slide to determine one or more attributes of the slide, and to generate an order or sequence of operations to be thereafter performed on the slide.
Abstract:
Systems and methods that enable automated processing of specimens carried on microscope slides are described herein. In some embodiments, the system can include, for example, a slide ejector assembly having a slide staging device configured to receive a slide and an over-travel inhibitor that includes a first vacuum port positioned to draw a first vacuum between the slide and a standby platform as the slide is moved across at least a portion of the standby platform. The over-travel inhibitor includes a first sensor for detecting a presence of the slide on the standby platform. The system can also include a transfer assembly to transport slides away from the slide ejector assembly. The transfer assembly can include a floating transfer head having a vacuum port for drawing a partial vacuum for holding the slide.
