Abstract:
Systems and methods to detect sleep stages of a subject analyze physiological parameters of the subject in combination with a subject's reactions to stimuli of increasing intensity and/or stimuli having different modalities. Stimuli are provided until a predetermined level of probability is reached for the accuracy of an estimation of the sleep stage of the subject.
Abstract:
The present invention relates to a patient interface and a patient interface system comprising a responsive material and a method for preventing the formation of red marks due to wearing a patient interface (10) that is pressing against the skin of a patient (14) for a longer time and/or for reducing air leakages of the patient interface (10) that may result from an unintended shift of the patient interface (10) on the patient's face. The responsive material is configured for alternating the pressure exerted by the cushion element (18, 26) on the patient (14), and/or the area on the patient where the pressure is exerted by the cushion element in response to a physical quantity acting on the responsive material. The formation of red marks and of air leakages can be reduced or even avoided by means of the responsive material.
Abstract:
The present invention relates to a patient interface device and system for delivering continuous airway pressure to a patient (14). The patient interface system comprises a patient interface (12) and at least one bone anchor (24, 26) fixed to the patient (14). The patient interface (12) is attached to the patient (14) by connection to the at least one bone anchor (24, 26). This is realized by coupling elements (32, 34) as part of the patient interface device.
Abstract:
A system for delivering sensory stimulation a sensor; a sensory stimulator configured to deliver sensory stimulation to a patient during a sleep session, the sensory stimulation having varying stimulation intensity levels; and a computer system. One or more physical processors being programmed with computer program instructions which, when executed cause the computer system to: determine sleep stage information of the patient based on brain activity information of the patient during the sleep session from the sensor; provide input to the sensory stimulator based on the determined sleep stage information of the patient, the provided input causing the sensory stimulator to deliver the sensory stimulation to the patient; obtain stimulation response information from the patient, the stimulation response information including patient brain response to the delivered sensory stimulation; and determine a range of the stimulation intensity levels within which the patient brain response reaches a threshold.
Abstract:
Typically, high NREM stage N3 sleep detection accuracy is achieved using a frontal electrode referenced to an electrode at a distant location on the head (e.g., the mastoid, or the earlobe). For comfort and design considerations it is more convenient to have active and reference electrodes closely positioned on the frontal region of the head. This configuration, however, significantly attenuates the signal, which degrades sleep stage detection (e.g., N3) performance. The present disclosure describes a deep neural network (DNN) based solution developed to detect sleep using frontal electrodes only. N3 detection is enhanced through post-processing of the soft DNN outputs. Detection of slow-waves and sleep micro-arousals is accomplished using frequency domain thresholds. Volume modulation uses a high-frequency/low-frequency spectral ratio extracted from the frontal signal.
Abstract:
An electrode configured to provide electrical contact with skin of a subject is provided. The electrode includes an electrode body configured to be removably coupled with the skin of the subject and to receive electrical signals from and/or transmit electrical signals to the skin of the subject, and an electrical coupling that facilitates coupling the electrode to an external computing system. The electrode body includes a conductive silicone material configured to enable uptake or diffusion of moisture from the skin of the subject over which the electrode body is disposed; and a detergent configured to facilitate a flow of ions through the conductive silicone material.
Abstract:
The invention relates to a shaving device for skin hairs. The device comprises a skin-contacting surface structure (14, 15), a cutter (6) for cutting hairs in a hair-cutting area (16), a shape-changing smart material (7), and a controller for controlling activation of the shape-changing smart material during use of the shaving device. The shape-changing smart material is configured, arranged and effective to adapt the relative position and/or relative orientation between at least part of the skin-contacting surface structure (14) and at least part of the hair-cutting area (16).
Abstract:
A patient interface face contact element includes a surface for contacting the face of a patient and a connection face for coupling the patient interface face contact element to a support using a magnetic coupling. The support is also provided as well as the complete patient interface. Headgear strap clips can also be retained magnetically.
Abstract:
The invention provides a health device for automatically administering skin pressure-based therapies to a user. The device comprises one or more actuator members, each comprising a smart shape-changing material of a class which is disposed to change shape in response to a change in temperature or to the application of an electrical stimulus. The actuator members are controlled by a controller to apply pressure to one or more points on a user's skin.
