In-line heating of dialysis fluids

Dialysis systems and methods for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a dialysis machine for transferring dialysate to a patient from a dialysate source. The dialysate may flow from the dialysate source through a cartridge or cassette (e.g., a disposable cartridge or cassette) positionable within the dialysis machine. The cassette includes a fluid flow channel. The dialysis machine includes a heating chamber for in-line heating of the dialysate in the fluid flow channel. The fluid flow channel is arranged and configured to provide turbulent flow of the dialysate through the fluid flow channel to provide increased heat transfer from the heating chamber to the dialysate.

Systems and methods for the conditioning of cerebrospinal fluid

Systems and methods for treating biologic fluids are disclosed. Some disclosed embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject, heat CSF to a target temperature, cool CSF to a target temperature, apply light treatment to CSF, separate cells via their dielectric properties, apply spiral and/or centrifugal separation, introduce additives to target particles, and/or apply combinations thereof. The method may include the steps of withdrawing fluid comprising CSF, treating the fluid, and returning a portion of the treated fluid to the subject. During operation of the system, various parameters may be modified, such as flow rate.

COMBINED BLOOD PUMP AND OXYGENATOR SYSTEM AND RELATED METHODS
20230022901 · 2023-01-26 ·

A blood pump-oxygenator system comprises at least one blood pump, an oxygenator, inflow and outflow cannulas, connected to form a closed series circuit operable as a cardiopulmonary bypass system for extracorporeal processing of the patient's blood. The blood pump conveys blood through the circuit from the patient into the inflow cannula, through the oxygenator and out of the outflow cannula back into the patient. A manifold is connected between the inflow and outflow cannulas so blood passes through the manifold, wherein the manifold accommodates the blood pump and the oxygenator to form a recirculation loop configured to recirculate at least part of the blood in the circuit so the blood passes over the oxygenator multiple times. An extra blood pump is positioned at the outflow cannula to deliver a set volume to the patient, controllable independently from the blood pump that circulates the blood in the manifold including the oxygenator.
