Abstract: The invention pertains to a device for the automatic examination of blood samples with one test station, in which blood is taken from a supply vessel and is fed through an aperture in a part held in an aperture holder. At least one test head is provided, to which is fed from a first magazine holder, supply vessels with blood, and from a second magazine holder, aperture holders are fed. After performance of at least one measurement on one aperture holder, the used aperture holder and the used supply vessel are removed from the test head and the test head is cleaned by a cleaning device.

Abstract: The invention pertains to a device for the safe removal of blood from a supply vessel with an aperture holder in which a part having an aperture is held and to which a capillary is attached, whereby the supply vessel can be closed by a cover part. The cover part a region through which the capillary can be inserted into the supply vessel when the cover part is closed. Furthermore, the supply vessel and the aperture holder have a locking mechanism, so that the supply vessel can be locked to the aperture holder.

Abstract: A flow device for use in a hemorrhaging time measuring apparatus comprises a housing through which the blood to be tested flows under a suction effect. In its interior the housing has a separating wall which is arranged transversely with respect to the direction of flow of the blood through the housing and which has at least one aperture therein. Disposed upstream of the aperture is a suction tube for sucking the blood through the housing. The suction tube extends into a cavity within the housing which is upstream of the aperture in the separating wall, with the downstream end of the tube disposed in the vicinity of the aperture. The blood is sucked into the device under a constant suction effect and thrombus formation takes place in the region of the aperture.
