The present disclosure relates to a medical pump drive comprising a pump housing and a pump motor provided in the pump housing. The pump drive also includes a rechargeable voltage source for storing electrical energy, or a rechargeable battery, for a voltage supply of the pump motor and a magnetic section for magnetically coupling of further pump sections, and/or for magnetically driving of elements, in particular a magnetically driven pump rotor. The pump also includes an electronic controller. The disclosure further relates to a pump, an induction charging station, a tube set, and a blood treatment apparatus.

Medical pump drive, pump and medical treatment apparatus

Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.

Blood treatment systems

The disclosure relates to a safeguarding module, a method, and a system for safeguarding an apparatus in the medical environment against an unauthorised operation of the apparatus, wherein the authorisation is dependent upon a linking event between two linking partners within the framework of an operation of the apparatus, wherein the apparatuses are connected via a network, and wherein one of the linking partners is an item which is used during the operation of the apparatus. The system comprises a plurality of apparatuses, wherein in each case an apparatus comprises a safeguarding module, comprising:

This disclosure relates to a method for determining a fluid balance between a first volume flow in a first section of a fluid circuit and a second volume flow of a second section of the fluid circuit. The method may also include adjusting, assuming or detecting a first temperature in the first section of the fluid circuit and a second temperature in the second section of the fluid circuit, or detecting a temperature difference between the first and the second sections. The method may also include detecting a second volume flow in a second section of the fluid circuit and forming a balance from at least the first volume flow and a corrected value of the second volume flow. The corrected value is determined from the detected second volume flow and the second temperature and/or the temperature difference.

Balancing method and balancing unit being independent of temperature disturbance

The invention relates to a medical treatment apparatus comprising a tube set, a peristaltic pumpfor conveying fluid, and a monitoring apparatusfor monitoring the occlusion of the positive displacement elementsA,B of the peristaltic pump. In addition, the invention relates to a tube setfor a medical treatment apparatus, and to a method for monitoring the occlusion of the occlusion elements of a peristaltic pump for conveying a fluid for a medical treatment apparatus. The invention is based on the fact that the occlusion of the positive displacement elementsA,B of the peristaltic pumpis monitored in order to monitor the fluid flow in the hose line. For this purpose, the electrical resistance or a variable which correlates with the electrical resistance is measured between a first and a second electrodeA,B, the first electrodeA being arranged on the hose lineupstream of the occlusion elementsof the peristaltic pumpand the second electrodebeing arranged on the hose line downstream of the occlusion elements such that an electrical contact is produced between the first and second electrodeA,B and the fluid flowing in the hose line. The electrodesA,B are preferably integral component parts of a connecting piece, by means of which the hose segmentA to be inserted into the peristaltic pumpis fixed in the form of a loop.
