The second chamber (7) is delimited or enclosed by the at least one gas-permeable and liquid-impermeable membrane (9) and is located inside the first chamber (3) or is substantially enclosed by the first chamber (3) such that the biological fluid surrounds the second chamber (7).

Abstract: A dispensing device for a dental substance which comprises a body formed in a single piece. The body connects a first passageway and a second passageway which extend along different paths. The body further comprises a nozzle with a free dispensing end. The second passageway extends into the nozzle and tapers toward the dispensing end. The invention helps to reduce manufacturing costs, and helps facilitating handling of the device.

Abstract: A device for use in retracting a gingiva from a human tooth by widening a gingival sulcus with a dental composition. The device comprises a cannula with a free end having an opening for dispensing the dental composition. The free end is shaped to be inserted with its front in the entry of the gingival sulcus, and to laterally displace the gingiva from the tooth as the cannula is moved in the gingival sulcus. The invention may help to achieve a reliable and cost effective gingival retraction treatment.

Abstract: An arrangement allowing a person to climb up and/or down an object, such as a high-voltage mast, the arrangement including an elongate, rail-type profiled element that is provided with at least one guiding part extending along the profiled element, and a part for absorbing force transmission. A climbing aid is also provided, comprising two climbing consoles with one respective foot supporting area and a guiding section that embraces or grips the guiding part and a holding section which at least partly rests against or on the profiled element opposite the guiding section.
