Abstract:
The invention provides a patient interface (10) comprising a patient interface element (12, 14, 15) for delivering breathing gas to a patient, and a forehead support (30). One of the forehead support and the patient interface element comprises a shaft (50) and the other comprises a hollow tube (51) in which the shaft is received, with the shaft slidable within the tube to permit adjustment of the position of the forehead support relative to the patient interface. The shaft and hollow tube are rotatable between a free and locked configuration. This provides a simple to use adjustment mechanism with few components.
Abstract:
A patient interface device is described for delivering a gas to a patient, the patient interface comprising a fastening means for fastening the patient interface to the user, the fastening means consisting of an element adapted for engaging the user's nose during use, wherein the fastening means is adapted for being fixed to said nose by exerting a pressure on said nose substantially in the width direction of said nose; and associated method.
Abstract:
An electroencephalography (EEG) system includes a support configured to be positioned at least partially around the head of a user, an EEG electrode configured to be supported by the support and to be positioned for contacting skin of the user, an actuator operatively coupled to the EEG electrode and configured to move the electrode in at least two dimensions, including an axial dimension and a lateral dimension to enable the EEG electrode to contact the skin at different locations, and one or more physical processors operatively connected with the EEG electrode and the actuator. The one or more physical processors being programmed with computer program instructions which, when executed cause the one or more physical processors to: obtain an impedance signal from the EEG electrode; and actuate the actuator to move the EEG electrode based on a comparison of the obtained impedance signal with an impedance threshold.
Abstract:
The present disclosure pertains to a system and method for delivering sensory stimulation to a user during a sleep session. The system comprises one or more sensors, one or more sensory stimulators, and one or more hardware processors. The processor(s) are configured to: determine one or more brain activity parameters indicative of sleep depth in the user based on output signals from the sensors; cause a neural network to indicate sleep stages predicted to occur at future times for the user during the sleep session; cause the sensory stimulator(s) to provide the sensory stimulation to the user based on the predicted sleep stages over time during the sleep session, and cause the sensory stimulator(s) to modulate a timing and/or intensity of the sensory stimulation based on the one or more brain activity parameters and values output from one or more intermediate layers of the neural network.
Abstract:
The present disclosure pertains to a system and method for managing a sleep session of a subject. Managing the sleep session is based on cardiac activity in the subject during the sleep session. Cardiac activity, as monitored via one or more sensors worn on an extremity of the subject and/or placed at a distance from the subject, is used to determine periods of slow wave sleep. Sensory stimulation is delivered to the subject during the periods of slow wave sleep to enhance slow wave activity. Wearing a sensor on an extremity, and/or placing a sensor at a distance from the subject during sleep, as opposed to the subject wearing an EEG cap, is more comfortable for the subject.
Abstract:
A patient interface face contact (14) element comprises a surface for contacting the face of a patient, and a connection face for coupling the patient interface face contact element to a support (15) using a magnetic coupling (30). 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 patient interface (10) comprising a patient interface element (12, 14, 15) for delivering a breathing gas to a user and a forehead support (30). One of the forehead support and the patient interface element comprises a shaft (60) and the other comprises a hollow tube (62) in which the shaft is received, with the shaft slidable within the tube to permit adjustment of the position of the forehead support relative to the patient interface element. One of the shaft and hollow tube are elastically deformable between a deformed configuration in which the shaft can be slid within the tube and a released configuration in which the sliding of the shaft within the tube is blocked.
Abstract:
A headgear assembly is disclosed for use in a patient interface assembly adapted to communicate a flow of gas with an airway of a patient comprising: at least a first headgear portion (9, 11) disposed during use on a first side of a patient's face in an area close to a first eye of the patient; a first stabilization member (2) operatively coupled to the first headgear portion so as to limit the movement of the headgear portion in a direction towards the first eye; and a patient interface assembly comprising such a headgear assembly.
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 device with a patient interface (12) and at least one connector pair (22), comprising itself two connector parts, attached to the patient interface (12) and the patient (14) via a tissue anchor, respectively. One of the connector parts comprises a magnet and the other one a magnetically responsive element. Both connector parts are attracted to one another through the magnetic forces.
Abstract:
The present disclosure pertains to a system configured to facilitate prediction of a sleep stage and intervention preparation in advance of the sleep stage's occurrence. The system comprises sensors configured to be placed on a subject and to generate output signals conveying information related to brain activity of the subject; and processors configured to: determine a sample representing the output signals with respect to a first time period of a sleep session; provide the sample to a prediction model at a first time of the sleep session to predict a sleep stage of the subject occurring around a second time; determine intervention information based on the prediction of the sleep stage, the intervention information indicating one or more stimulator parameters related to periheral stimulation; and cause one or more stimulators to provide the intervention to the subject around the second time of the sleep session.
