  • Patent number: 12260958
    Abstract: The invention relates to the field of medical fluid management devices, in particular dialysis machines. The object of the invention is to design methods and devices, such that the monitoring and control of medical fluid management devices from a remote site are possible. To do so, the screen content of the output device of a fluid management device is transmitted at least partially to an output device of a remote control unit. The screen content optionally has user interfaces, which can be selected on the remote control device and lead to changes in the control of the transmitting medical fluid management device.

  • Publication number: 20230398273
    Abstract: The present disclosure relates to a medical treatment apparatus which includes at least one port, a device for closing, a compressed-air source and a control device and/or closed-loop control device. The port serves to establish fluid communication between at least one fluid line of the treatment apparatus associated with the interior of a treatment apparatus and a connector of a fluid line of a disposable associated with the exterior of the treatment apparatus. The sealing device is designed as a rinsing cap and serves to seal an interior of the port with respect to an exterior of the treatment apparatus. The compressed-air source is used to introduce air into the port along at least one sterile-air line. The control device and/or closed-loop control device is programmed to cause the compressed-air source to build-up and/or maintain a predetermined minimum overpressure in the sterile-air line, the compressed-air source and/or inside the port.

  • Publication number: 20230364313
    Abstract: The invention relates to an access system 1 for a medical device, which system has a housing body 21 in which an inner pipe portion 22 for transporting a medical fluid is formed, which portion is enclosed by an outer pipe portion 24 so as to form an empty space 23 for receiving a disinfectant fluid, the housing body 21 having an opening 25 that can be closed by a closure element. The access system 1 according to the invention is characterised in that a measuring electrode 30 and at least one counter electrode 31, 32 are arranged in the housing body 21 such that the measuring electrode 30 interacts with the counter electrode via the empty space 23. The measuring electrode 30 allows an electrical signal to be input such that a current flowing between the measuring electrode and the counter electrode or a voltage applied between the measuring electrode and the counter electrode can be evaluated.

  • Publication number: 20230158217
    Abstract: The invention relates to an extracorporeal blood treatment apparatus comprising a blood treatment unit 1 that is divided by a semipermeable membrane 2 into a first compartment 3, which is part of a fluid system II, and a second compartment 4, which is part of an extracorporeal blood circuit I. The invention also relates to a method for operating a blood treatment apparatus of this kind. The blood treatment apparatus according to the invention has a pressure-based checking device 32 which interacts with the control unit 31 for a valve device 21 and is designed such that a fluid connection between an upstream portion 20A and a downstream portion 20B of a flow path 20 for a special operating mode can only be established if the pressure-based checking device 32 detects an operating state in which it is ensured that fluid in the flow path 20 for a special operating mode flows towards a flow path 10 leading to a drain 11.

  • Patent number: 10507273
    Abstract: A method of filling a container, preferably containing at least one concentrate, with the concentrate being formed such that it forms at least one liquid concentrate or a part of a liquid concentrate on its solution in or its mixing with a liquid, preferably water, the liquid concentrate or the part of the liquid concentrate being suitable for preparing at least one dialysis solution, includes filling the container via a balance chamber system of a dialyzer. The balance chamber system has chambers from which the liquid is conveyed into the container in the form of repeating cycles. The pressure of the liquid being conveyed is measured during a cycle of the filling phase of the container, and an alarm signal is emitted and/or the filling of the container is stopped if a measured maximum pressure in a cycle does not reach or does not exceed a limit value.
