The invention relates to a dialysis device having an extracorporeal blood system, a dialyzing fluid system, a dialyzer and a control unit, wherein the dialysis device has a heating mechanism for heating the blood in the extracorporeal blood system before entry into the dialyzer or in the dialyzer as well as a cooling mechanism for cooling the blood in the extracorporeal blood system after exiting the dialyzer and wherein the control unit is configured such that the blood is heated before entry into the dialyzer or in the dialyzer to a dialysis temperature which is above the body temperature of the patient and is cooled back to the body temperature of the patient after exiting the dialyzer.

A dialysis machine, in particular a peritoneal dialysis machine, has a heating device for heating a container containing a dialysis solution, in particular a peritoneal dialysis solution. The heating device is configured such that the heating of the dialysis solution by the heating device takes place non-uniformly at points.

The present invention is directed to a device and a method, particularly suitable for temperature adjustment of a patient and/or suitable for fever treatment and/or normothermia and/or hypothermia. The device comprises at least one connection to at least one reservoir suitable to provide infusion fluid; at least one assembly controller for controlling the temperature and/or flow rate of the infusion fluid; at least one temperature controller adapted for cooling and/or heating the temperature of the infusion fluid so that the infusion fluid is delivered with a pre-set temperature; and/or at least one flow controller for controlling the flow of the infusion fluid; and at least two outgoing ducts; wherein the flow controller is adapted to feed the outgoing ducts with different flow rates.

Methods, devices and systems for improving sleep (including reducing sleep onset and maintenance of sleep duration), enhancing, or increasing sleep, including (but not limited to) treating sleeping disorders such as insomnia.

Methods, systems and devices for enhancing sleep, including enhancing the quality of sleep, reducing sleep onset time, increasing total sleep time, treating insomnia, and/or treating other neurological disorders by non-invasive temperature regulation of the frontal cortex prior to and/or during sleep. Described herein are thermal applicators that include phase change materials and/or evaporative cooling, as well as headgear for securing the applicators comfortably against the appropriate region of the user's head.

Preclinical and clinical studies have shown that the autonomic nervous system (parasympathetic and sympathetic nervous systems) show reliable changes across the sleep wake cycle. Most importantly, the parasympathetic nervous system shows increased activity during sleep consistent with its role in regulating rest. Further, patients with insomnia show reduced parasympathetic activity and/or increased sympathetic activity during sleep consistent with a neurobiological model of hyperarousal. Described herein are methods and apparatuses that activate the parasympathetic nervous system in response to a diving reflex; a sustained diving reflex may, surprisingly, lead to enhancing sleep. The apparatuses and methods described herein may specifically and/or selectively activate this reflex may play a therapeutic role in the modulation of sleep in insomnia patients.

Method, systems and devices for treating insomnia by non-invasive hypothermic treatment are described. In general, these devices, systems and method enable cooling of the frontal cortex prior to and/or during sleep to enhance sleep, which may be particularly beneficial to treat insomnia.

A heater-cooler apparatus of an extracorporeal perfusion system comprises at least one fluid circuit 102, 104 providing a supply of a heat transfer fluid to the perfusion system, a cold storage unit 266, and a refrigeration unit 250 for charging the cold storage unit 266. The cold storage unit 266 comprises a chamber 312 containing a liquid that freezes at a temperature above that to which the heat transfer fluid is cooled by the refrigeration unit 250, and a passage through which the heat transfer fluid is conveyed, the passage extending through the chamber 312. This allows a more effective cold storage unit to be provided.

Methods, systems and devices for reducing anxiety, including increasing relaxation and/or calm. In some variations these methods may include reducing anxiety, increase relaxation and/or calm by non-invasive temperature regulation of the frontal cortex prior to and/or during sleep. The subject may have an anxiety disorder, or may not have a diagnosed anxiety disorder.
