The blood purification system includes an extracting device capable of searching the histories accumulated in the storage device and extracting a desired one of the particular incidents, a calculating device capable of calculating a time when the particular incident extracted by the extracting device occurs a predetermined or more number of times as a frequent-occurrence time slot, and a display control device capable of displaying the frequent-occurrence time slot calculated by the calculating device on a display during a current session of blood purification treatment.

Provided are a blood purification system, etc., to enable more achieve more efficient purification of blood. A blood purification system includes a line through which a liquid containing blood or filtrate flows, a plasma separation device to separate a plasma component from blood flowing through the line, a factor separating device to separate a factor component which is a pathogenic factor from the plasma component, a detector to detect blood information relating to blood flowing through the line, a liquid control mechanism to control flow of liquid in the line based on control parameters, a parameter acquisition module to input the detected blood information into a learning model trained to output predetermined control parameters when predetermined blood information is input, and acquire control parameters output from the learning model, and a control module to control the liquid control mechanism based on the acquired control parameters.

The present invention relates to a dialysis machine having an extracorporeal circuit in which a dialyzer is located which has a chamber on the blood side which is flowed through by blood and a first pressure sensor, which is located upstream of the chamber on the blood side in the direction of flow of the blood, for determining a first pressure value and a second pressure sensor, which is located downstream of the chamber on the blood side in the direction of flow of the blood, for determining a second pressure value, wherein the dialysis machine has first means for determining the pressure difference between the second pressure value and the first pressure value, second means for determining the dynamic viscosity of the blood on the basis of the determined pressure difference, of the blood flow rate through the chamber on the blood side and of one or more characteristic properties of the dialyzer and third means for determining the hematocrit or the hemoglobin value of the blood on the basis of the determined viscosity, and wherein the dialysis machine has a control or regulation unit which is configured such that it sets the blood flow rate and/or the dilution rate and/or the ultrafiltration rate such that the time change of the hematocrit and/or of the hemoglobin value does not exceed a limit value or lies in a desired value range.

A dialysis method to enable a patient to undergo both peritoneal dialysis and extracorporeal blood treatments is disclosed. The method includes determining, via a base unit controller, whether a peritoneal dialysis treatment or an extracorporeal blood treatment is to be performed. If the peritoneal dialysis treatment is to be performed, the method includes operating first software instructions that cause a base unit to use a first fluid stored in a fluid container. If the extracorporeal blood treatment is to be performed, the method includes operating second software instructions that cause the base unit to use a second, different fluid from an online source and selectively move the second, different fluid to a blood treatment unit for use in the extracorporeal blood treatment. The blood treatment unit is operable with the base unit to perform the extracorporeal blood treatment on a patient.

A method comprising: establishing a wireless connection between a first medical device and a second medical device, comprising: receiving, by the first medical device, via a short-range wireless technology protocol, connection information related to the second medical device; and establishing, by the first medical device, a wireless connection with the second medical device based on the connection information.

A renal therapy system is disclosed. In an example, a renal therapy system includes a dialysis fluid pump, a control processor for controlling a treatment performed by the dialysis fluid pump, and a user interface device in operable communication with the control processor.

A portable hemodialysis system is provided including a dialyzer, a closed loop blood flow path which transports blood from a patient to the dialyzer and back to the patient, and a closed loop dialysate flow path which transports dialysate through the dialyzer. In addition, the hemodialysis system includes two reservoirs which can be alternately placed in the dialysis flow path using various controllable fluid valves. The hemodialysis system may include a sorbent filter in the dialysate flow path which filters used dialysate. Alternatively, the filter may be positioned within a separate closed loop filter flow path which is isolated from the blood flow path and dialysate flow path. For this embodiment, the hemodialysis system includes additional controllable fluid valves which selectively connect the filter flow path to the reservoir which is not currently providing dialysis treatment to a patient.

A sorbent canister utilized when performing a dialysis treatment during hemodialysis (HD) or peritoneal dialysis (PD) is provided. The sorbent canister includes inlet and outlet ports that include a threaded interface for connection to inlet and outlet tubes for circulation of dialysate through the sorbent canister. Upon disconnection from a dialysis machine, a pressure relief cap can be threaded onto the threaded interface to seal the fluid in the sorbent canister while allowing for off-gases to be expelled when a pressure within the sorbent canister exceeds a threshold pressure, thereby preventing a rupture in the canister body. In one embodiment, the pressure relief cap includes a deformable insert with a hole formed therein that is closed in an uncompressed state and opened in a compressed state. In another embodiment, the pressure relief cap includes a diaphragm that mates with a feature of the inlet or outlet port.

A dialysis system comprising: a dialysis machine; a communication module configured to communicate using a short-range wireless technology protocol; data storage configured to store data corresponding to identities of one or more short-range wireless devices; and a processor configured to: identify presence of a short-range wireless device; and cause the dialysis machine to carry out an action when one or both of i) the presence of the short-range wireless device is identified, and ii) the presence of the short-range wireless device is no longer identified.

A medical treatment machine, such as a dialysis machine (e.g., a home dialysis machine, such as a home hemodialysis machine or a home peritoneal dialysis machine) can receive a digital prescription file that defines parameters of a medical treatment to be administered to a patient. The digital prescription file can be prepared and delivered in such a way that the medical treatment machine can confirm that the issuer (e.g., provider) of the digital prescription file is an authorized issuer without having any a priori knowledge of the particular issuer. The digital prescription file can be delivered irrespective of the inherent security (or lack thereof) of the transmission medium in a tamper-evident format using minimal resources necessary to verify the validity of the digital prescription file and its issuer. The digital prescription file may be delivered to the dialysis machine using a network cloud-based connected health system.
