Abstract
A hose pump for the conveyance of a fluid conducted in a hose, with several squeezing elements and with a hose bed, which has a hose inlet, a hose outlet, a guide surface, and a counter support, in which the hose is placed lying on the guide surface and is pressed by the squeezing elements against the counter support for the conveyance of the fluid found in the hose when the hose pump is operated in a conveyance direction. The hose pump has a guiding-out device for the automatic guiding of the hose out of the hose bed, and the guiding out of the hose takes place by means of the guiding-out device during the operation of the hose pump opposite its conveyance direction. For the development of an as low-cost as possible but nevertheless reliable guiding-out device, an elevation, located on the hose outlet of the hose bed, is provided, which protrudes over the guide surface and via which the hose is conducted.
