ABSTRACT:
An automatic device prepares blood films or smears on microscope slides. The device has essentially one moving part, namely a carriage which holds the slide, and which is movable back and forth along a frame. The slide is dispensed from a magazine, onto the carriage, and the carriage moves to a position where a drop of blood is conveniently placed onto the slide. The carriage then moves to a position permitting contact between the blood and a spreading blade mounted on a flexible member. The carriage is moved in a forward direction, causing the blade to move relative to the slide, creating the blood smear. The slide is then lifted from the carriage and moved onto a storage platform. Meanwhile, the blade is cleaned as it passes over a cleaning pad on the carriage. Movement of the carriage in both directions insures that both sides and the end of the blade are cleaned. The device includes a bar code reader and printer, making it possible to read a bar code located on a specimen container, and to print indicia onto the slide, which may correspond to the coded information. The device also includes apparatus for automatically rejecting blank slides which have stuck together.
