The invention relates to a dialysis treatment unit in which the connecting line to the central concentrate supply is also rinsed in the rinsing or cleaning process in order to prevent deposits therein.

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 simple, natural method of preserving organisms includes sealing biological blood or organisms in a shell filled with resin, curing the resin, and solidifying the shell for a long time to form amber. The biological blood or organisms can be preserved for a long time. Scholars of later generations may research the integrity of the biological blood or organisms of the present days. Otherwise, the biological blood or organisms may be of no researching meaning and purposes due to pollution or oxidation and dehydration. The organisms of the present days may be reconstructed after 100 years by using technologies of that time. Thus, the organisms being extinct due to pollution can be reconstructed. Diversities of organisms on the earth can be maintained. Precious genes of the organisms of the present days can be preserved for thousands years. It contributes greatly to the study of evolution of organisms.

This disclosure relates to dialysis systems and methods. In some implementations, a dialysis system includes a dialysis machine with a fluid line and a drain line, a blood line set configured to be connected to the dialysis machine, and a drain apparatus coupled to the dialysis machine. The drain apparatus includes a chamber configured to receive an end of a patient line of the blood line set, an inlet line, an outlet line, and a valve. The inlet line has a first end configured to be coupled to the chamber and a second end configured to be coupled to the fluid line of the dialysis machine. The outlet line has a first end configured to be coupled to the chamber and a second end configured to be coupled to the drain line of the dialysis machine. The valve is configured to control flow of fluid through the outlet line.

Dialysis machines comprising a feed arrangement (170) to supply a dialysis fluid to a dialyzer (150) during dialysis treatment and a return arrangement (171) to remove the dialysis fluid from the dialyzer during dialysis treatment and forward it to an exit (129); a feed recirculation circuit (172) to allow a fluid of the feed arrangement to be re-circulated in a fluid loop path comprising, at least a portion of, the feed arrangement and the feed recirculation circuit and a return recirculation circuit (173) to allow a fluid of the return arrangement to re-circulate in an auxiliary fluid loop path comprising, at least a portion of, the return arrangement and the return recirculation circuit. A controller (160) configured to perform disinfection by re-circulating a disinfectant and/or a heated fluid through said fluid loop path and/or through said auxiliary fluid loop path. The dialysis machine (1) further comprises a feed forward arrangement (172) connected to the fluid loop path and arranged to enable a fluid of the feed arrangement (170) to be forwarded to the exit (129) by-passing the auxiliary fluid loop path.

An extracorporeal circuit has been conceived including: lines (16) which include passages for blood or a medical liquid; a connector (38, 40) at a free end of each of the lines (16); a cassette (18) supporting the lines, and dummy connectors (42, 44) attached to the cassette (18) and each adapted to form a mating connection with a respective one of the connectors (38, 40) at the free ends of the lines (16), wherein the connectors (38, 40) are arranged in accordance with a sequence in which the lines (16) are attached for a blood treatment session or are grouped in accordance with types of liquids to flow through the lines (16) during the blood treatment session. The extracorporeal circuit may be a circuit for dialysis and the circuit includes a hemodialyzer. Further, the connectors (38, 40) and dummy connectors (42, 44) may each be one of a male or female luer lock connector, and the dummy connectors (42, 44) may include both male and female connectors.

Methods, sorbent cartridges and cleaning devices are disclosed for refurbishing sorbent materials. In one implementation among multiple implementations, a medical fluid delivery method includes: providing a sorbent cartridge including H.sup.+ZP within a casing for a treatment; and after the treatment, refurbishing the H.sup.+ZP while maintained within the casing via (i) regenerating the non-disinfected H.sup.+ZP by flowing an acid solution through the casing, (ii) rinsing the regenerated H.sup.+ZP while maintained within the casing, (iii) disinfecting the regenerated and rinsed H.sup.+ZP by flowing a disinfecting agent through the casing, and (iv) rinsing the regenerated and disinfected H.sup.+ZP while maintained within the casing. Multiple batch sorbent refurbishing implementations are also disclosed.

A mobile dialysis therapy cart includes a top shelf; a cycler compartment positioned below the top shelf, the cycler compartment sized and shaped to house an APD cycler; a fluid bag management compartment sized and shaped to house at least two fluid bags; a drain compartment positioned below the fluid bag management compartment; and a plurality of wheels. The cart may include a heating device associated with the fluid bag management compartment and/or a sanitizing light source for sanitizing a location of a disposable set associated with the fluid bags.

The present application relates to a method for controlling a disinfection status of a heater and/or cooler for human body temperature control during extracorporeal circulation. The temperature control is conducted by use of a heat exchanger and a temperature control liquid circulating through the heat exchanger and the heater and/or cooler. The inventive method comprises using a long term disinfectant in the temperature control liquid, measuring and preferably recording the concentration of the disinfectant in the temperature control liquid and deducing a disinfectant status of the temperature control liquid from the measured concentration of the disinfectant in the temperature control liquid.

The present application relates to a method for disinfection of a temperature control device for human body temperature control during extracorporeal circulation which temperature control is conducted by use of a heat exchanger and a temperature control liquid circulating through the heat exchanger and the temperature control device. According to the present application, the temperature control device is connected to a temperature control liquid supply and, during operation of the temperature control device for human body temperature control, a disinfectant is selectively added to the temperature control liquid supply upstream of the temperature control device.
