Abstract
The invention provides for applying a treatment medium such as blood smears to slides. A plurality of suction cups are adapted to be conveyed in an endless path, defining a loading station. Smear slides are pushed upon and attached one by one to the suction cups. At a treatment station, a treatment medium can be applied to a smear on the side of a slide opposite the suction cup.
Claims11
Apparatus for applying treatment medium to slides, such as slides carrying blood smears, comprising a plurality of suction cups, each cup being approximately the size of the viewing area on said slide, conveying means supporting said cups and adapted to convey the suction cups in an endless path including a horizontal section, means defining a loading station at which smear slides may be attached one by one to the suction cups by being pressed thereto, said suction cup being attached to one side of said slide under the area of the slide which receives said smear, means defining an unloading station at which the slides may be detached from the suction cups, and means defining at least one treatment medium station at which treatment medium can be applied to a smear in said area on the one side of a slide opposite to the side attached to a suction cup when such slide is located on a horizontal section of said endless path and the cup is located under the slide, whereby said suction cup covers and protects said area of said slide while said medium is being applied.
Apparatus for applying treatment medium to slides, such as slides carrying blood smears, comprising an endless conveyor means carrying suction cups of elastic material having a size and shape conforming to the viewing area on each of said slides, the backs of the slides adhering to said suction cups during an operation of the apparatus, the point of adherence being in the viewing area opposite the part of the slide which receives a specimen, a loading station for pressing each slide to be treated onto a suction cup and an unloading station for detaching the slides from the suction cups, the path of the said conveyor means having an upper horizontal reach above which are disposed one or more treatment distributors, and a lower horizontal reach, means defining a drying zone at said lower reach, an unloading zone and a loading zone these latter zones being respectively opposite the unloading station and the loading station, and said conveyor means having connecting curve reaches between the said horizontal reaches, the arrangement being that the planes of the slides are practically horizontal when they travel in the horizontal reaches of the conveyor means.
