Abstract: A bag clip for tightly sealing plastic bags. The bag clip comprises two limbs (1, 2) hinged together at respective one ends thereof and intended to receive therebetween that portion of the bag where a seal is to be effected when the limbs are moved towards one another with the bag portion therebetween, wherewith the other ends of the limbs have arranged thereon a manually openable snap-lock arrangement (8-11, 13, 14) which closes automatically when the limbs are brought together to a sufficient extent. Each of the mutually facing surfaces of the limbs (1, 2) has arranged thereon an opposing channel, the one channel (4) being wider than the other channel (20), with upstanding free channel walls.

Abstract: The sampling device includes means for spraying or flushing the mucous membrane with a liquid, in order to release cells therefrom, and a container for collecting the liquid together with cells suspended therein. The spray means of the device includes a rinsing or flushing pipe (3) having connected thereto a spray nozzle (4) which is connected to a liquid container, and a suction tube (5) for removing the liquid, together with the suspended cells, to the collecting container (19) by suction.

Abstract: Apparatus for taking samples of cells of small tumors with the aid of fine-needle puncturing techniques. The apparatus includes a hand-grip (1) having removably connected thereto a syringe provided with a thin cannula (2). The cannula (2) is connected, via a coupling (18), to a motor (12,13,15,16) which can be energized for driving the cannula (2) in an oscillating, reciprocatory movement. The cannula (2) is connected to a container (4) having arranged for movement therein a suction plunger (5), which is arranged to create a vacuum in the cannula (2), for drawing a cell sample thereinto.

Abstract: An arrangement in apparatus for preparing solutions from dry harmful materials, such as cytostaticum, radioactive, toxic and allergy-producing substances, includes a glass ampoule (1) for accommodating the dry substance. The ampoule communicates with a device (4) for enlarging the internal volume of the ampoule, so as to equalize the pressure generated therein when preparing the solution.Solvent is introduced into the ampoule (1) and solution removed therefrom through a cannula (8) which is constantly sheathed against contamination by means of an elastic sheath (10). The sheath is provided with self-sealing means (11) arranged to sealingly abut the ampoule (1) when withdrawing solution therefrom, in a manner to tightly seal the ampoule against the surroundings.

Abstract: A method and device for processing a body liquid specimen used for diagnostical examination. The specimen is brought to settle for a predetermined time in a first chamber of a container which has a second, separate chamber containing a certain amount of a fixative, whereupon a portion of the specimen containing a predetermined amount of a concentrate having high concentration of settled body cells is separated and confined in a third chamber, which is formed by partitioning off a portion of the first chamber. Thereafter the remaining body liquid is removed from the container, and said second and third chambers are interconnected in order to form a common, sealed chamber in which the concentrate is mixed with the fixative.
