Abstract

This disclosure teaches a system and method for monitoring an extracorporeal blood circuit of a patient and identifying a needle dislodgement. The method includes identifying a potential needle dislodgement event based on changes in pressure of the extracorporeal blood circuit, searching for a heart rate of a patient by analyzing an optical backscatter signal from an optical sensor attached to the extracorporeal blood circuit or by analyzing a pressure signal representative of the pressure in the extracorporeal blood circuit, and verifying the potential needle dislodgement event is a needle dislodgement based on the absence of the heart rate.

Abstract

The invention relates to a computer system (1) for supporting a user in the process of preparing or carrying out a blood-treatment session of a patient, said session being carried out using a blood-treatment device (100). The computer system (1) has a computing device (5), an input interface (501), and an output interface (503). Here, the input interface (501) is configured for entering input values by means of the user, said input values comprising setting values which are proposed or have been proposed by the user in order to set machine parameters of a blood-treatment device (100) in order to carry out an extracorporeal blood treatment of the patient during the treatment session. Additionally, the computing device (5) is programmed to predict, on the basis of the input for the input values, at least one value occurring at a point in time during the blood treatment session or a curve, for at least one blood parameter of the patient or for at least one test parameter, over a period of time during the blood-treatment session. The computing device (5) can transmit the predicted value or the predicted curve to the output interface (503), by means of a signal transmission, and from the output interface to an output device (505) for example.

Abstract

Systems and methods are described for a dialysis machine (such as a hemodialysis machine) with proximity and motion sensors used to control simple functions of the dialysis machine through contactless interfacing that would otherwise normally be handled with glove changes. The sensors may be used to perform the same functions as using the touch screen display or the control panel of the dialysis machine. In an implementation, one or more of the sensors may be a proximity sensor that receives short-range wireless signals from a credential device of an operator, and one or more of the sensors may be a motion sensor enabling the operator to move a hand or foot near the sensor to enable contactless interfacing with the dialysis machine.

Abstract

A computing system for determining a systematic training strategy for the user is provided. The computing system includes a user device that uses one or more sensors to obtain partial pressure of oxygen (PO2) levels of a user over a period of time. The user device provides previous PO2 levels to a personalized erythropoiesis model generation computing platform. The computing platform obtains individualized user data for the user indicating or more previous hematocrit and/or hemoglobin measurements for the user. The computing platform determines an individualized erythropoiesis model for the user based on the one or more previous hematocrit and/or hemoglobin measurements and the previous PO2 information, and employs the individualized erythropoiesis model to determine predicted hematocrit and/or hemoglobin measurements. The computing platform performs one or more actions based on the one or more predicted hematocrit and/or hemoglobin measurements.

Abstract

A method for determining a next hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) dosage for a first patient using a patient HIF-PHI model is provided. The method includes obtaining population patient data indicating HIF-PHI dosages and hemoglobin measurements for the patients. Then, virtual patient avatars are generated based on the population patient data. Each of the virtual patient avatars indicates a set of personalized model parameters for a HIF-PHI model. A plurality of HIF-PHI models are determined for the virtual patient avatars. Using the HIF-PHI models, one or more HIF-PHI treatment schemes for administering the HIF-PHI dosages is determined. Subsequently, the HIF-PHI treatment schemes along with a hematocrit and/or hemoglobin concentration for a patient are used to determine a next HIF-PHI dosage for the patient, and the next HIF-PHI dosage is administered for the patient.

Abstract

The present invention relates to a blood treatment device, preferably a dialysis device, which is designed to be used with a disposable component, preferably with a cassette system, and which comprises: - a coupling region for the disposable component and - a control unit designed to carry out a plurality of pressure measurements at different times during a process of coupling the disposable component to the blood treatment device, on the basis of which pressure measurements the quality of the coupling of the disposable component to the blood treatment device can be determined. The present invention also relates to a method for monitoring a process of coupling a disposable component to a blood treatment device.
