Abstract: An apparatus for collecting and measuring body fluid comprises a measurement container which is provided with a fluid inlet (2) at its uppermost end and at its lowermost end has a fluid outlet (3) where a rod-shaped valve means (4) is arranged, wherein the measurement container is constructed with an opening in the upper area through which opening the valve means may be activated, a fluid collection bag connected to the fluid outlet and suspended from the measurement container and flexible connecting element (7), e.g. a bellows, which is mounted on the one hand on a rim region of the opening in the measurement container and on the other hand on the valve means, as the flexible connection (7) allows axial movement of the valve manes (4, 5) relative to the measurement container (1).

Abstract: A device for the supply of oxygen and/or other gases to a patient comprises a flow conduit which is, at its one end, provided with means for fitting with e.g. an oxygen supply and, at its other end, closed, and having between its two ends a patient connection member (1) comprising upstream and downstream tubular members for insertion into a patient's nostrils and wherein the patient connecting member is provided with means (7) to increase the flow resistance beyond the first tubular member so as to create substantially even outflow amounts through the two respective tubular members.
