Title:
TISSUE SPECIMEN TREATER
Document Type and Number:
Japanese Patent JPS63144258
Kind Code:
A
Abstract:
Tissue specimen treatment apparatus of the multi-chamber type having a plurality of chambers (22), for instance arranged in a circle, and means for transporting a specimen for treatment to selected such chambers in a prescribed sequence, is characterised by a containment vessel (20, 24) for at least the (open) upper ends of the chambers and by cover means (26) movable with and enclosing the transporting means while separating the interior of the containment vessel from the ambient atmosphere. The cover means (26) preferably closely overlies the tops of the chambers (22) to minimise the volume of the containment vessel, and is formed with a small volume transfer enclosure (32) to receive a specimen during transport. The cover (26) may have a close fit to the containment vessel, sufficient to restrict exchange of gases etc. between the external atmosphere and the containment vessel, or more positive sealing arrangements may be provided - e.g. labyrinth, flexible or liquid seals - to prevent flows between the vessel and the environment. Additionally or alternatively, positive venting of the containment vessel by withdrawl of its atmosphere may ensure that all leakages are into the vessel.
