Abstract: The container consists of a hose wound to four spiral coils and of a holding device for fixing the spiral coils parallel and spaced to each other, such that the individual spiral coils are substantially to be subjected from all sides with a heating medium. The apparatus includes a source of hot air into which the container is insertable. The temperature of the heating air is regulated by a measuring device and a controlling device. By using the heating air, an effective heating of the infusion liquid and the transfusion liquid is achieved, and a simple handling is possible without dripping bags.

Abstract: The hose pump has plates forming the first pressure members and limbs which form second pressure members and which are actuated by the plates. The limbs are fastened at one end to a base plate, in such a way that second portions formed at the other ends are parallel to and near one another and the surfaces, facing one another, of the middle portions are inclined towards one another, in order to move the limbs to-and-fro by means of the projections of the plate. By means of resilient elements which on the one hand rest against webs in the frame and on the other hand against the plate, the plate is held in contact with the drive. As a result of these measures, the efficiency and the effect of the hose pump can be improved.

Abstract: An apparatus for and a method of extracting physiological liquids and adding of a coagulation preventing element thereto such to control the added quantity of the coagulation preventing agent in accordance with the quantity of flow of the physiological liquid such that at all times a set ratio between the flow quantity of the physiological liquid and of the coagulation preventing agent is maintained. This allows an improvement of the yield and of the durability of the physiological liquid. The apparatus comprises an emitter element, a transducer including two oscillators which are to be applied onto a plastic hose flowed through by the physiological liquid, comprises further a demodulating circuit which generates a signal which is proportional to the velocity of speed within the plastic hose, comprises further a converter which generates a DC-signal which is proportional to the flow quantity. The measuring proceeds without contact and without any influence onto the medium being measured.

Abstract: A separating vessel, intended to be inserted into a separating centrifuge, consists in a hollow cylinder manufactured from a soft PVC, whereby connection conduits for the feed of the liquid to be separated and for the discharge of the separated fractions open into said hollow cylinder. The separating centrifuge comprises a centrifuge rotor which is rotatable around a first axis of rotation and is driven by a driving motor via a driving arrangement. There is provided further a support mounted to the centrifuge rotor to rotate around a second axis of rotation. The two axis of rotation extend perpendicularly to each other. There is provided furthermore a connecting part receiving the connection conduits, which connecting part is mounted at one end against rotation and lies on the first axis of rotation. The supporting device rotates in order to equalize a twisting of the connecting conduits.

Abstract: A hose pump comprising a number of movable pressure elements composed of a first pressure device and a second pressure device. The first pressure device is constituted by an element which is movable to-and-fro with respect to a counter pressure surface and the second pressure device contains elements movable to-and-fro with respect to a hose. The pressure devices are arranged next to one another and are driven by a common drive, in order to rhythmically compress the hose within two neighboring regions. The drive comprises cam discs structured to correspond to the number of pressure elements, the apex of crown points of the cam discs being mutually offset with respect to one another, in order to rhythmically compress the hose which is placed in the hose pump, and thus, to convey the medium which is to be pumped.
