A therapeutic collar comprising an elongate body made from a flexible material for extending around at least a portion of the neck of a patient. The body has a length approximating the circumference of the neck, two thermoelectric devices for overlying two carotid arteries in the neck and two thermoelectric devices for overlying of two vertebral arteries in the neck when the elongate body is secured around the neck of the patient. At least one cooling tube is carried by the elongate body and extends in the vicinity of each of the thermoelectric devices for removing heat from the thermoelectric devices.

A sleep testing method, a sleep testing apparatus, a sleep-aiding device, and a sleep-aiding method are described. The sleep testing method comprises: acquiring an electroencephalogram signal of a user; processing the electroencephalogram signal to obtain energy values of the electroencephalogram signal in a plurality of set frequency bands; calculating a relative energy value of the electroencephalogram signal in the plurality of set frequency bands; and determining a sleep state, mental stress and the degree of fatigue according to the relative energy value. According to the sleep testing method, the sleep state, the mental stress, and the degree of fatigue of a user can be simultaneously determined just according to an electroencephalogram signal, and a plurality of pieces of testing data related to sleep can be obtained in a single instance of testing.

A system that selectively controls temperature within a device such as a neck/head wrap is disclosed. The system can include a pump system having a reservoir that holds a liquid, an element that regulates temperature of the liquid within the reservoir; a pump that draws the liquid from the reservoir; and a distribution manifold attached to the pump hose that receives and distributes the liquid to at least two devices (e.g., cervical collars). The system is also equipped to be selectively monitored, for example, via a smartphone, tablet or computer.

A cervical collar that facilitates therapeutic hypothermia is provided and includes a cooling device having a front portion and a back portion fixedly coupled to the front portion on one side and removably coupled to the front portion on an opposite side. A fastening device removably couples the back portion to the front portion on the opposite side. The cooling device induces hypothermia in at least a portion of a patient. A sensor is provided that measures a physical characteristic of the patient.
