A centrifugal smearing sample container holder (1) is provided with: a base part (2) including a bottom surface section (2a) that accommodates a sample container, a packing, and slide glass by being stacked, side surface sections (2b), (2c) formed on both sides of the bottom surface section (2a), locking sections (2e), (2f) respectively formed in the side surface sections (2b), (2c), a back surface section (2d) formed on a back side of the bottom surface section (2a), and a curl section (2g) formed in the back surface section (2d); and a holding part (3) including a handle section (3a) disposed on a front side of the bottom surface section (2a) along a short direction of the base part (2), arm sections (3e), (3f).

Abstract: A centrifugal smearing device including a sealed rotating container that houses a chamber with a slide glass removably attached for holding a liquid sample to smear cells with a centrifugal force onto the slide glass, and a base housing the sealed rotating container and including rotational driving means for rotating the sealed rotating container, the sealed rotating container includes a main body capable of housing the chamber and a lid for closing an upper surface opening portion of the main body, a seal portion for sealing a space between the main body and the end face of the upper face opening portion is provided on an outer circumferential edge of the lid, and a scattering protection wall is formed at an inside of the seal portion so as to protrude downward to hide the seal portion from inside so that a liquid does not scatter onto the seal portion.

Abstract: The present invention addresses the problem of providing a centrifugal smearing device and a sealed rotating container in which liquid components do not leak to an outside of the sealed rotating container. To solve this problem, in a centrifugal smearing device (30) including a sealed rotating container (34) that houses a chamber (10) with a slide glass removably attached for holding the liquid sample to smear cells in the liquid sample with a centrifugal force onto the slide glass, and a base (31) housing the sealed rotating container (34) and including rotational driving means (32) for rotating the sealed rotating container (34), the sealed rotating container (34) includes a main body (40) capable of housing the chamber (10) and a lid (42) for closing an upper surface opening portion of the main body (40), and has a storage section (46) for storing liquid scattered from the chamber (10) during being centrifuged, formed on an inside face of the main body (40).

Abstract: Apparatus for dyeing tissues sampled from a living body for the purpose of observing immunoreaction of the tissues has a dyeing tray with a plurality of plateaus arranged in parallel disposition. A slide is so placed over each plateau that a wedge-shaped gap of capillary dimension is formed between the plateau and the undersurface of the slide to which a sampled tissue is attached. A liquid drip surface and a liquid discharge port are formed at one end of the top surface of each plateau. A liquid delivery port is formed on a side wall of the tray so as to communicate with the liquid discharge port. The liquid delivery port and the drip surface are always exposed. A dyeing liquid or a rinsing liquid is dripped onto the exposed drip surface and spreads into the gap for dyeing the tissue or rinse the relevant parts. After the dyeing or rinsing, the used liquid is sucked and discharged by way of the liquid delivery port.

Abstract: A device for dyeing tissues of living bodies for immune response observation comprises dyeing block on which are formed a plurality of adjoining base portion each having a flat upper surface. On one side of the base portion is formed a ridge, and on the other side of the base portion is formed a supporting surface which is slightly higher than the ridge. A slide glass having a tissue attached to one surface is placed above each of the base portion with the surface thereof facing the upper surface of the base portion, so as to bridge the ridge and the supporting surface in such a manner that a thin wedge-shaped gap is defined between the upper surface of the base and the undersurface of the slide glass. Dyeing liquid is dripped from above onto the upper surface of the base portion which is not covered by the slide glass. The dripped dyeing liquid spreads into the wedge-shaped gap by capillary action, whereby the tissue on the undersurface of the slide glass is dipped in the liquid and dyed.

Abstract: An apparatus for the collection of blood via a collapsible inflow pipe into an inflatable bag having an anticoagulant prefilled therein. The bag is placed on a weighing platform coupled to a load cell, which produces an electric voltage signal representative of the weight of the blood being collected in the bag. The load cell is mounted on a swing cradle capable of oscillation about a horizontal axis, so that the bag is shaken during blood collection for intimately intermingling the collected blood and the anticoagulant. When a predetermined amount of blood is collected, as ascertained from the voltage output of the load cell, a controller actuates a collection stop mechanism thereby causing the same to tightly grip and collapse the inflow pipe.

Abstract: A cell for placing solid matter on a piece of slide glass in such a manner that it is rotated in a centrifugal separator, which is formed integrally by mold forming of synthetic resin thereby to be disposable, and a base plate of a cell portion has an elasticity so as to be easily engaged with a hook provided on a holder in which the base plate is held.

Abstract: An apparatus for automatically pretreating and paraffining biological specimens in a single vessel for the preparation of specimen blocks to be microtomed into thin slices for microscopical study. A rotary selector valve assembly with a built-in gate valve placed a plurality of reagent vessels, containing various reagents including molten paraffin, in and out of communication with the processing vessel in a prescribed sequence. An air pump coacts with directional control valves to evacuate the processing vessel for drawing the successive reagents into same via the rotary selector valve assembly and to deliver gas under pressure into the vessel for the discharge of the reagents therefrom back into the respective reagent vessels. For automating the apparatus a level sensor is provided to the processing vessel in order to close the gate valve and to set the pump out of operation whenever a reagent is drawn into the processing vessel to a predetermined level.
