Automated smear making apparatus

摘要

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.

主权项

1. A method for automated preparation of a slide using a smear cartridge of a smearing subsystem, said method comprising the steps of:
moving a slide towards a smear surface of a smearing tape of the smear cartridge, wherein the smear surface is included on a blade of a perforation of the smearing tape, and wherein the smearing tape is initially wound within an input reel and coupled to a take-up reel of the smear cartridge; contacting the slide with an exposed smear surface of the smearing tape, wherein the smear surface is exposed when the position of the blade of the perforation is extended by a deflection component of the smear cartridge as the smearing tape is drawn from the input reel and into the take-up reel; and transporting the slide across the exposed smear surface.
