Abstract: An apparatus for supplying air and at least one additional gas to a respirating subject has a container with an open end for receiving air, which is connected to a tubing system for conveying gas to the subject. The additional gas is supplied from an additional gas source via a metering system and a supply line to the container. As gas is supplied to the subject during inspiration phases by a compressor, air will flow into the container via the open end. At the same time a flow of additional gas is supplied to the container via a point of entry. During expiration phases gas will be diverted via a flow divider to flow back to the container via the supply line for the additional gas. A homogeneous and controllable concentration of additional gas is obtained within the container before each inspiration phase. The apparatus requires only a few components, making it a low cost apparatus, but it provides a good control of the concentration of additional gas supplied to the patient.

Abstract: An examination table for supporting a patient in a medical examination apparatus has a positioning plate and a floor stand, the positioning plate being adjustable in height and able to be tilted. The examination table is very simple and space-saving in construction, but still allows a tilting of the positioning plate into a vertical position, by virtue of the floor stand having a curved girder which has a base end at the floor fastened rotatably about a horizontal shaft, and the positioning plate is provided with a mount that is movably attached to the girder so that the mount with the positioning plate can be moved along the longitudinal direction of the girder.
