Abstract: A pressure transducer arrangement featuring a holding element for a number of pressure transducers. For each pressure transducer a group of electronic counter-contacts is provided on the holding element that are in contact with the contacts of the pressure transducer while it is attached to the holding element. All counter-contacts are connected to one common signal transfer device.

Abstract: The holding plate for medical equipment, in particular for medical blood pressure measuring, blood withdrawal, infusion and transfusion apparatuses which have a plate-like fixing device with which they can be fixed to the holding plate, has two parallel guide tracks (3, 4) with grooves (4, 5; 27, 28) for accommodation of the plate-like fixing device. At least one of the grooves (4, 5) has a stop (13). A spring-pretensioned (6) catch stud (10) protrudes from the holding plate (1), the stop (13) and the catch stud (10) having a distance between them, based on the longitudinal direction of the guide tracks (3, 4), which corresponds to the length of the plate-like fixing device.

Abstract: A pressure transducer for measuring the pressure of a fluid, in particular for invasive blood pressure measurements, comprises a housing with two chambers that are separated from one another in a fluid-proof fashion, whereby the first chamber accommodates a pressure transducer that is fastened onto a substrate and may be charged with the pressure of the fluid to be measured. The substrate lies in both chambers and has contact surfaces for the direct connection of an electric plug-in connector within the region of the second chamber. This plug-in connector comprises parallel tongues between which the substrate and a housing cover may be accommodated. One of the tongues carries electric spring contacts.

Abstract: A blood sampling apparatus includes a housing (1) closed off by a rotatable cover (4), which in turn seals off the housing completely with a seal (7). The cover has a threaded sleeve (9), which cooperates with a piston rod for axial displacement of a piston (2). The housing cover has an opening closed off by a sterile filter (11). When the piston (2) is displaced, this piston rod always remains completely inside the housing (1), so that no bacteria, other kinds of germs or any other kind of contamination can penetrate the housing from the outside (FIG. 1).
