An apparatus for extracorporeal treatment of fluid and a process of setting up a medical apparatus for the delivery or collection of fluids are disclosed. According to the apparatus and the process, a control unit (10) is configured calculate set values of two or more of the fluid flow rates by imposing that an emptying time of containers of fresh fluid (16, 20, 21, 26) and/or a filling time of a waste container is substantially same as, or multiple of, the emptying time of one or more of the other containers of fresh fluid.

The invention concerns a control or regulating device with a control or regulating unit, which both controls or regulates a volumetric blood flow flowing through a blood pump as well as a volumetric flow of a gas able to flow through a gas exchange unit.

An article configured to warm and monitor a patient during a dialysis treatment, the article includes one or more heating elements. The article also includes one or more sensors configured to monitor a condition of the patient during the dialysis treatment. The article also includes a fabric portion configured to receive the one or more heating elements and the one or more sensors and position the one or more heating elements and the one or more sensors on the patient during treatment. The article also includes a transmitter configured to transmit information from the one or more sensors to a dialysis machine and an electrical connector configured to provide power to at least one of the one or more heating elements and the one or more sensors.

A servicing regime for a disposable set of a medical fluid therapy machine is disclosed. In an example, a medical fluid delivery system includes a medical fluid therapy machine operating with a disposable set over multiple treatments to mix for each treatment at least one concentrate with purified water to form a medical fluid. The medical fluid delivery system also includes a sensor configured to measure an accuracy of the medical fluid mixed by the medical fluid therapy machine. The sensor is configured to produce a mixing accuracy output. The medical fluid delivery system further includes a computer programmed to analyze the mixing accuracy output provided by the sensor to determine whether the disposable set needs to be replaced.

A medical system, usable for example in connection with a dialysis apparatus, may utilize radar waves for monitoring a patient, a medical area, or an object. The medical system includes at least one sending device for sending radar waves, and at least one receiving device for receiving reflected radar waves. The medical system further includes an evaluation unit for evaluating the reflected radar waves which have been received by the at least one receiving device, resulting in obtaining a result, and an output device for outputting the result or a signal based on the result.

A peritoneal dialysis (“PD”) system includes a housing; a dialysis fluid pump housed by the housing; a dual lumen patient line extending from the housing; a filter set including a final stage filter located along a first line, and which includes a second line in parallel with the first line, the first line in fluid communication with a first lumen of the dual lumen patient line, and the second line in fluid communication with a second lumen of the dual lumen patient line; a pressure sensor located within the housing and positioned so as to sense a static or substantially static PD fluid pressure in the second lumen while fresh PD fluid is pumped through the first lumen and the final stage filter; and a control unit configured to use the sensed static or substantially static pressure in a pressure control routine for the dialysis fluid pump.

An optical connector includes a first sub-assembly that is factory-installed to a first end of an optical fiber and a second sub-assembly that is field-installed to the first end of the optical fiber. The optical fiber and first sub-assembly can be routed through a structure (e.g., a building) prior to installation of the second sub-assembly. The second sub-assembly interlocks with the first sub-assembly to inhibit relative axial movement therebetween. Example first sub-assemblies include a ferrule, a hub, and a strain-relief sleeve that mount to an optical fiber. Example second sub-assemblies include a mounting block; and an outer connector housing forming a plug portion.

A medical treatment system, such as a peritoneal dialysis system, may include a control and other features to enhance patient comfort and ease of use. For example, a cycler device may include a heater bag receiving section and a lid mounted to cover and uncover the heater bag receiving section, potentially enabling faster heating of a dialysate. A user interface may be moveable to be received into the receiving section and covered by the lid, if desired. The system may detect anomalous conditions, such as tilting of a housing of the system, and automatically recover without terminating a treatment. The system may include noise reduction features, such as porting pneumatic outputs to a common chamber, and others. The system may also automatically detect any one of several different solution lines connected to the system, and control operation accordingly, e.g., to mix solutions provided by two or more lines and form a needed dialysate solution. A cassette control surface may be arranged to have one or more ports that can detect a presence of a liquid, e.g., to identify if a cassette is leaking or has otherwise been compromised.

A gas delivery system is provided. The gas delivery system includes a pump operable to receive blood from a patient. A gas transfer unit is in fluid communication with the pump and operable to receive the blood from the pump and deliver a therapeutic amount of xenon gas to the blood. A patient connector withdraws and/or infuses the blood into the patient.

The present invention relates to various methods of treatment using a novel blood perfusion device. The blood perfusion device comprises a perfusion chamber comprising at least one compartment A and at least one compartment B, compartment A comprising a first opening which is in direct fluid communication to a second opening, wherein the first opening of compartment A is in direct fluid communication to a first port of the perfusion chamber and the second opening of compartment A is in direct fluid communication to a second port of the perfusion chamber; and compartment B comprising a first opening which is in direct fluid communication to a second opening, wherein the first opening of compartment B is in direct fluid communication to a third port of the perfusion chamber and the second opening of compartment B is in direct fluid communication to a fourth port of the perfusion chamber, wherein compartment A is separated from compartment B by at least one membrane, said membrane being configured to prevent cells from crossing the membrane.
