A facial skin indentation preventer has a central base core surrounded by an entrapment flap and a securing flap. The core and flaps have at least a single layer of soft moleskin, felt, or similar material forming an outer skin-contact layer that is non-adhesive. A rigid component is attached to the outer skin-contact layer in a center of the preventer, thereby defining a central base core. The central base core can have a cannula or similar item placed thereon. The flaps are then folded inwards, over the rigid component, creating a cannula pocket above the rigid component and entrapping and holding the cannula therein. An entrapment hinge and securing hinge ensure the folds remain rounded and soft. A flap attachment is used to lock the securing flap to the entrapment flap and ensure the cannula stays within the cannula pocket.

This disclosure includes a method for treating a patient suffering from alcohol withdrawal. The method comprises administering an effective amount of oxygen to the patient and administering an effective amount of nitrous oxide to the patient. In some embodiments, the effective amount of oxygen and the effective amount of nitrous oxide are administered to the patient via a nitrous oxide sedation system.

Various embodiments of a patient interface device, such as a mask, nasal pillow, or nasal cannula, that includes an adhesive layer provided on a surface thereof that is structured to temporarily bond to the skin of a user of the patient interface device. The adhesive layer may include a bonding agent, such as a polymer gel, having a residual extraction force of between about 50 grams and about 200 grams.

Provided are concepts for controlling a high flow nasal therapy (HFNT) device used by a subject. In particular, physiological and movement parameter values of the subject are leveraged in order to generate a control signal for the HFNT device. These parameters may indicate an activity level of the subject, as well as the condition of the subject, providing information useful for setting appropriate operating conditions of the HFNT device. Thus, a means for automatically controlling a HFNT device based on needs of the subject may be provided, improving subject comfort during therapy, and ease of use of the HFT device.

According to an aspect, there is provided a ventilator system. The ventilator system comprises: a mouthpiece, to be received within a user's mouth, wherein the mouthpiece comprises: a passage for permitting a flow of gases through the mouthpiece between a first side of the passage to be inside the user's mouth and a second side of the passage to be outside the user's mouth; a passage adjustment component for selectively adjusting a flow area of the passage; and one or more sensors mounted on the mouthpiece, wherein the sensors comprise a pressure sensor configured to measure a pressure at the first side of the passage; and a controller configured to control: a flow rate and/or concentration of oxygen supplied to the user through a nasal cannula; a total flow rate of air and oxygen supplied through the nasal cannula; and/or the flow area of the passage, based on the pressure measured by the pressure sensor.

Lightweight, portable oxygen concentrators that operate using an ultra rapid, sub one second, adsorption cycle based on advanced molecular sieve materials are disclosed. The amount of sieve material utilized is a fraction of that used in conventional portable devices. This dramatically reduces the volume, weight, and cost of the device. Innovations in valve configuration, moisture control, case and battery design, and replaceable sieve module are described. Patients with breathing disorders and others requiring medical oxygen are provided with a long lasting, low cost alternative to existing portable oxygen supply devices.

This invention relates to headgear and a patient interface, or components of a headgear or patient interface, such as a nasal cannula. In one embodiment is a size adjustable headstrap to be provided as a headgear or a part thereof, in another is a portion of a headstrap or component for association therewith in which the portion or component facilitates improved location of the strap upon a user's face, in another embodiment is a system for encapsulating or covering a connector from contact with a user's face or facial skin, in another embodiment is a face mount part or body for a patient interface of a particular configuration, and in yet a further embodiment is a gases flow manifold for delivering of gases to a patient interface of a particular configuration for improved patient comfort.

A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

The present invention is a respiratory monitoring device which uses 2+ sensors to map respiratory motion in patients to interpret into a respiratory effort and severity score. The core components of the invention are contact-based sensors that measure relative motion of the chest, abdomen, and/or other key anatomical features, a processing unit which takes in the data from all sensors, an algorithm that analyzes and compares the data from each sensor to understand relative motion and interpret it into clinically-relevant information, and a display screen that shares this information with clinicians. The sensors are connected to each other and the information processing unit which shares data with the screen for display of a respiratory severity score based on analysis of Thoraco-Abdominal Asynchrony (TAA) or similar indicators of respiratory effort as measured by the sensor network and analyzed by the algorithm.
