Patent number: 11979472Abstract: A digital communication module for a self-contained medical device communication platform is disclosed herein. In an example, a digital communication module is communicatively coupled to a therapy module of a medical device for relaying medical device data to an electronic medical record (“EMR”) server that is connected to a medical network. The digital communication module is connected to at least one other digital communication module via a wireless proprietary network that is separate from the medical network. The digital communication module determines that the medical device data from the medical device is to be transmitted, via the wireless proprietary network, to one of the other digital communication modules that is connected to the EMR server via the medical network. The other of the digital communication modules receives, and then routes the medical device data to the EMR server via the medical network.Type: GrantFiled: June 2, 2021Date of Patent: May 7, 2024Assignee: Gambro Lundia ABInventors: Bernd Wittner, Aghohgo Ekpruke

Publication number: 20230256146Abstract: A system, methods, and apparatus having a circular buffer for the reply of renal therapy machine alarms and events are disclosed. An example renal therapy apparatus includes a therapy operations processor configured to generate alarms, events, and high fidelity medical device data. The renal therapy apparatus also includes a memory device having a circular buffer configured to store a duration of medical device data. The renal therapy apparatus further includes a control processor configured to receive a stream of medical device data from the therapy operations processor, and write the stream to the circular buffer such that a most recent duration of the stream is stored. The control processor is also configured to detect an occurrence of an alarm or event, and create a reply record that includes an identifier of the alarm or event and the medical device data that is stored in the circular buffer.Type: ApplicationFiled: July 8, 2021Publication date: August 17, 2023Inventors: Gerard PRINDLE, Andrew HODGES, Klaus OBERGFELL, Bernd WITTNER, Rikard HULT

Patent number: 8771215Abstract: A machine (1) for extracorporeal blood treatment comprises a device (2) for ultrafiltration of a liquid through a semi-permeable membrane (3) of a blood treatment device (4), a first sensor (11) for ultrafiltration rate through the membrane, a second group of sensors (13) for measuring a trans-membrane pressure, an infusion line (16) with an infusion pump (17) and a programmed controller (14) for calculating a maximum infusion rate as a function of the transmembrane pressure. The machine is suitable for kidney failure treatments, such as hemofiltration and hemodiafiltration. In a relatively short time the machine enables a large quantity of corporeal blood to be removed from the patient.Type: GrantFiled: December 20, 2011Date of Patent: July 8, 2014Assignee: Cambro Lundia ABInventors: Claudio Tonelli, Bernd Wittner, Werner Beck, Helmut Hildwein, Reinhold Deppisch, Jonas Svensson, Bjorn Ericson
