Abstract: A medical pump, in particular an infusion pump for conveying a medium, includes a seating for a hose clamp which is separate from the pump and arranged on the hose. Two clamping portions of the hose clamp which can be moved relative to each other can be transferred into a closed relative position in which they pinch off the hose arranged therebetween in such a manner that it is not possible for any medium to flow through the interior of the hose. Moreover, the clamping portions can be moved with respect to each other into an opened relative position in which the hose arranged between the clamping portions is not pinched off, so that the medium is able to flow through the interior of the hose. The pump is distinguished in that a sensor is provided thereon, in particular in the seating for the hose clamp, which sensor detects at least when the hose clamp is received in the seating—whether their clamping portions are in the closed or opened relative position.

Abstract: A medical instrument, in particular a machine for extracorporeal blood treatment, allows for execution of different programs with selectable program parameters. The medical instrument (11) comprises a read unit (14) which is capable of communicating with a transponder (15) carried along by the personnel. Said transponder (15) contains an identification (ID). In dependence on the identification, different access authorizations with regard to selecting programs and/or modifying program parameters are granted. In this manner, it is determined what settings and/or modifications may be carried out by the nursing personnel and what settings and/or modifications may be carried out by the technical service personnel.

Abstract: For automatic supply of an active substance to a patient's body (14) the supply rate (R) of an infusion pump (13) is evaluated. The supply rate is processed in a patient model (11) which receives the corresponding active substance data from a drug data bank (12). The patient model (11) calculates the concentration (CNactual) in the patient's body from the former values of the active substance supply. Said actual concentration value is fed to a concentration controller (17) which also receives a desired concentration value (CNdesired). The infusion pump (13) is controlled as a function of the difference obtained. The desired concentration value can be manually set on an input device (19) or is supplied by another control portion which generates e. g. a BIS level or an adequate signal from the patient's EEG, the BIS level being a measure of the depth of anaesthesia.

Abstract: The quantities of fluid which are fed to a patient (P) by fluid supply devices (10) and the quantities of fluid which are excreted by the patient as urine, wound drainage fluid or similar, received in corresponding receptacles (20a, 20b, 20c) are counterbalanced by a fluid manager (15). The fluid manager (15) controls the fluid supply devices (10) in accordance with the result of the counterbalancing process. Each receptacle (20a, 20b, 20c) comprises a receiving container (22) and a secretion quantity detector (21). The levels are transmitted wirelessly to the fluid manager (15) by data transfer devices (25). Each data transfer device (25) also supplies power to its allocated secretion quantity detector (21) by means of a battery. The data transfer device (25) can be set to a standby state of low power consumption to save battery power. It is awaken by a signal of the fluid manager (15) and set to the transmitting state.

Abstract: The infusion device comprises a central controller (10) and a plurality of infusion apparatus (12) each connected via a data channel (15) with the controller (10). Each infusion apparatus (12) is provided with a unique identification number. When an infusion apparatus (12) is connected to the controller (10) the identification number is requested and the controller (10) checks whether this identification number has already been allocated. If this is not the case, the controller (10) sends the inverted identification number back to the infusion apparatus (12). The infusion apparatus (12) accepts commands from the controller (10) only if the returned signal corresponds to the identification number.

Abstract: An infusion pump comprises a mobile self-contained functional basic module (10) with a pump portion and an energy storage means. For more sophisticated programming and performance tasks, the basic module (10) is inserted into an operating module (20) with an input device (27) for more complex inputs. Thus, the infusion pump may be used as a basic module (10) or as a combination of the basic module and the operating module (20).

Abstract: A medical pump device having a hose pump and a replaceable pump hose and provided with a reading means that reads a code mounted on the pump hose. The code corresponds to the deviation of the delivery volume of the individual hose from the set delivery volume. In dependence on the coding signals, the control signals for the pump drive are corrected so that defined delivery rates are obtained even with in wide hose tolerances.

Abstract: A pressure sensor for determining the pressure of a medium in an elastic hose section. A pressure member acts on a unilaterally fixed bar carrying an influencing member at its free end. This influencing member is a core of a coil arrangement, the position of the core changing the frequencies of the oscillator coils. Numerous pressure values are received at regular intervals and, subsequently, a representative pressure value is obtained by averaging.

Abstract: A dialytic apparatus for single-needle dialysis comprises a first pump in the artery conduit, which first pump in the first phase conveys blood from the patient into the expansion chamber while the vein conduit is shut off. At the same time, the second pump transports blood from the expansion chamber to the dialyzer. This regulation is performed in dependence from the pressure in the vein conduit so that the pressure decrease caused by ultrafiltration is counterbalanced. In the second phase, the first pump stands still and closes the artery conduit while the second pump conveys blood out of the expansion chamber to the dialyzer at a constant rate.

Abstract: The dialysis equipment has a dialysate path connectable to a dialysate source 1, and contains a feed pump 6, a dialyzer 10, and a controlled suction pump 13. During the operative phase, this dialysate path is traversed by the dialysate with a constant negative pressure being maintained in the dialysate chamber 101 of the dialyzer 10 relative to the blood chamber 102. In a subsequent measuring phase, the dialysate path is cut off from the dialysate source 1 and from a drain 15 via a valve device 2, 14. The same negative pressure is maintained in the dialysate chamber 101 as in the operative phase. The ultrafiltrate passing from the blood chamber 102 into the dialysate chamber 101 during the measuring phase causes the filling of a volume measuring device 5.
