  • Patent number: 5641683
    Abstract: An improved medical slide holder for use in medical procedures including automated microscopy. The slide holder comprises a rectangular frame adapted for receiving slides of differing thicknesses. Compensation for differing thicknesses is achieved through the disposition of two fastening caps, one for each end of the slides, the caps having resilient extending fingers which contact upper surfaces of the slides near their ends. Precision positioning of the slides within the holder is facilitated through provision of slide-supporting ledges having partitions to define positions of the slides; and precision positioning of the holder frame is facilitated through the provision of angled corners and notches each having a right angle and an obtuse angle. The slide holder has a recessed indentation in both the upper and lower locking caps to facilitate their removal once engaged to the frame, thus allowing slide specimens to be removed from the slide carrier for archiving purposes.
