The invention relates to a pressure transducer for measuring blood pressure for medical use, which can be connected by pressure to the vascular system of a patient, said transducer comprising a pressure measuring element for measuring the prevailing pressure in the fluid chamber, and also mechanical holding means for detachably mounting the pressure transducer onto the contact holder. The invention also relates to a contact holder for holding and for electrically contacting a pressure transducer for medical use.

So that a catheter can be made visible in ultrasound images easily and with relatively little effort, and hence positional control of a catheter can be enabled with relatively little effort, an ultrasound marking recognizable in the body of a living being by means of ultrasound is provided at the distal end of a catheter, wherein the catheter has a lumen, and the ultrasound marking is arranged in the lumen near the distal end such that it is removable via a proximal end of the catheter.

The medical regulating valve for adjusting the flow in an infusion or transfusion procedure has a housing (2), and a valve chamber (21) into which an inlet connecting piece and an outlet connecting piece (22, 23) open. A rotating piece has a cylindrical valve plug (41) which can be inserted in the valve chamber (21) to form a seal between the plug and the chamber. The valve plug, has, on its outer periphery, at least one groove (42, 43) opposite the connecting pieces (22, 23) connecting the connecting pieces with one another in terms of flow and having a cross-section changing in the peripheral direction. An insert (3) having the shape of an annular disc overlaps the valve chamber (21) and has, on its side facing the rotating piece (4), a number of markings (35, 36, 37) lying on concentric circles. Provided on the rotating piece (4) are a number of windows (45, 46, 47) which are offset with respect to each other in the peripheral and radial directions, each being opposite one of the markings (35, 36, 37).

A mounting for poles of jumps in equestrian sport. A dish-shaped pole receiver suspended on a generally vertical rail can be connected together by bolts, then fixed to a stand. The bolts, which are flanged such that the shaft is not as wide as the head, extend in multi-segmented slots having serially connected narrow, wide and further narrow portions. The width of the narrow portion of the slot corresponds to approximately the width of the bolt shaft, while the wide portion of the slot is wide enough to accommodate the bolt head. The slot can secure the bolts by firstly introducing the bolt head into the wide portion of the slot, then engaging the shaft with the narrow part of the slot until the shaft comes in contact with the further narrow portion. The further narrow portion, on which the shaft rests, gives way under a pre-determined vertical loading, so that the pole and pole receiver are forced downwards when this loading is exceeded, causing the shaft to deform the further narrow portion as it passes through.

摘要:
A mounting for poles of jumps in equestrian sport, with a dish-shaped pole receiver which is suspended on a generally vertical rail adapted to be fixed to a stand. The pole receiver and the rail can be connected together by bolts which extend in one or more multi-segmented slots having one or more serially connected narrow, wide and further narrow portions. The bolts are flanged, or headed such that the shaft is not as wide as the head. The width of the narrow portion of the slot corresponds to approximately the width of the bolt shaft, while the wide portion of the slot is wide enough to accommodate the bolt head. The slot is able to secure the bolts by firstly introducing the bolt head into the wide portion of the slot, then engaging the shaft with the narrow part of the slot until the shaft comes in contact with the further narrow portion. The further narrow portion, on which the shaft rests, gives way under a pre-determined and relatively low vertical loading, so that the pole and pole receiver are forced downwards when this loading is exceeded, causing the shaft to deform the further narrow portion as it passes through. Consequent disengagement of the pole and pole receiver from the stand reduces the risk of injury to a horse and its rider, as well as destruction or damage to the pole mounting.
