Abstract: A bone plate is formed with a throughgoing hole formed with a radially inwardly open outer groove. A screw fastener has a shaft engageable coaxially through the hole and a head of larger diameter than the shaft and adapted to bear axially on the plate around the hole. The shaft is formed offset from the head with a radially outwardly projecting ridge defining a radially outwardly open inner groove aligned radially with the outer groove when the fastener is fitted through the hole with the head bearing on the plate. An elastically deformable ring of a diameter generally equal to that of the hole at the outer groove is formed with at least one radially inwardly directed projection that, when the ring is fitted to the outer groove and the fastener is seated in the hole, projects radially inward into the inner groove of the fastener.

The tourniquet device has an inflation apparatus for inflating the connected compression cuff. In order to present a tourniquet apparatus that enables the most efficient and in particular fast inflation of the tourniquet cuff possible and at the same time the most error-free operation of the tourniquet apparatus possible, a parameter set for controlling an inflation process of the respective compression cuff is associated with each compression cuff and is stored in a data memory of the control apparatus. The parameter set associated with each compression cuff depends on the volume of the compression cuff.

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.

Abstract: A hose pump includes a hose bed having a counter support, a carrier disk rotatable relative to the counter support, and a number of pinch rollers and guide rollers arranged on the carrier disk. A guide roller is arranged between two consecutive pinch rollers, and the pinch rollers press a hose inserted into hose bed against the counter support, while pinching the hose when the carrier disk is rotating in the conveying direction to transport the fluid in the hose. To ensure reliable threading of a hose section of a pump hose, when the hose section is somewhat too short and to prevent unthreading of the inserted hose section during operation of the hose pump, the angular distance between a guide roller and the pinch roller preceding the guide roller in the conveying direction is greater than the angular distance between this guide roller and the pinch roller following the guide roller in the conveying direction.

In a development of such a bottle holder with which the infusion or injection device can be equipped as easily and as quickly as possible with a filled storage bottle, the invention proposes that the bottle receiver (2) is movable with respect to the spike (4) or with respect to the holding means (3) for the spike (4), and, when the bottle receiver (2) moves in the direction of the spike (4), a storage bottle arranged in the bottle receiver (2) is placed onto the spike (4) in such a way that the spike (4) punches an outlet opening into the storage bottle.

Abstract: A connecting system for connecting a medical tubular line to a medical fluid transfer system, the tubular line including a plug-in component with a first fluid channel and the fluid transfer system including a coupling component with a second fluid channel. The plug-in component can engage in the coupling component to establish a passageway for a medical fluid, which passageway connects the fluid channels to one another. By disposing a first passive transponder in the plug-in component and a second passive transponder in the coupling component at a distance below a predefined threshold value relative to one another, communication of a read/write unit with both transponders via a single antenna is made possible when the plug-in component is engaged in the coupling component so that identification data for the identification of the tubular line and the fluid transfer system stored in the transponders can be read by a read/write unit via a single antenna.
