A loop-back strap path and gripping arm secure respiratory headgear, reducing exposed ends, flapping, and adjustment misuse.

Coupling elements keep CPAP lower strap ends near the head, preventing shoulder drop, tangles, and hard-to-reach reattachment.

Adjustable headgear clips and cushions let one CPAP interface switch between nasal and oro-nasal fit to improve comfort and compliance.

Varying cushion thickness and an internal tie improve CPAP mask sealing, comfort, and pressure stability while reducing CO2 rebreathing.

Oxygen is redirected above the conchae to restore warming and humidification, reducing dryness and improving alveolar gas exchange.

Segmented vent slots and adjustable impedance improve CO2 washout while reducing noise, discomfort, and pressure loss in respiratory therapy.

Acoustic impedance sensing infers humidifier water quantity without disposable reservoir sensors, helping maintain effective respiratory humidification.

A paper or nonwoven mask body paired with an offset tube attachment cuts plastic waste, resists deformation, and helps prevent tube contamination.

Integrated pulse oximetry in a nasal cannula enables real-time patient monitoring and adaptive respiratory therapy adjustment.

An inflatable nasal seal conforms to facial contours and movement to maintain comfortable pressurized gas delivery during sleep.

A planar arched headband improves respiratory mask stability and comfort while simplifying manufacturing and reducing production cost.

Guide grooves beside mask anchor points help users align and attach the harness securely with less dexterity and coupling complexity.

A resilient textile mask housing flexes against pillows yet returns to shape, preserving seal integrity and sleep-position comfort.

A removable forehead pad adjustment frame shifts pad angle and position to redistribute pressure while keeping a ventilation mask stable.

A flexible vent wall lets one mask switch between nasal and oro-nasal sealing while reducing leaks, noise, and pressure loss.

Rigid headgear elements and a pliable overlay stabilize the mask seal while reducing nose pressure and movement during PAP therapy.

A flexible joint links nasal and mouth cushions to improve CPAP fit, seal stability, comfort, and home cleaning.

Replaceable adhesive strips secure the CPAP mouthpiece and nose pillow without headbands, improving comfort, fit stability, and user compliance.

A Venturi jet pump and tri-lumen patient circuit deliver low-pressure oxygen from a concentrator without compressor safety or calibration issues.

A resilient snap-fit connector secures oxygen mask tubing, reduces misconnection risk, and allows controlled release without damage.

A removable water tub, cradle, and hinged lid avoid heater plate overmolding while preserving heat transfer, easier assembly, and cleaning.

Pressure and flow signal fitting identifies patient interfaces and leak conditions, enabling more accurate respiratory therapy adjustment.

A dual-stiffness nasal seal uses a supple inner side and stiffened outer regions to improve CPAP mask comfort while maintaining a stable facial seal.

An expansion chamber with inward baffles attenuates blower and gas-flow noise in PAP therapy while preserving pressurized airflow to the user.

A mask-mounted sensor measures oxygen partial pressure in breathing tubing and triggers tactile alerts before pilot hypoxia is missed.

A foam-and-fabric headgear band attenuates NICU noise, secures respiratory tubes, and avoids adhesive-related skin damage.

Active suction and catalytic filtration clear residual ozone from ventilators, hoses, and masks after disinfection to prevent exposure and pollution.

Composite spirally wound tubing with insulation and conductive filaments helps maintain gas temperature and humidity while reducing heat loss and condensation.

A soft rubber eyeglass-mounted support uses a C-shaped hook and rotating base to stabilize nasal oxygen tubes while reducing ear pressure and friction.

A rolling hinge in the nasal mask seal shifts load away from the nasal bridge while maintaining a secure positive pressure therapy seal.

A mask-mounted sensor monitors oxygen partial pressure in breathing tubing and triggers tactile alerts before pilots miss hypoxia onset.

Oxygenator exhaust is captured and reused for nasal cannula support during ECMO, reducing extra oxygen equipment and improving ambulation comfort.

A bellows nasal seal with asymmetrical prongs improves CPAP fit, sealing, and comfort while reducing nasal irritation during sleep.

Angled dual nozzles and a stabilizing sleeve prevent syringe leakage, avoid air-first spraying, and balance drug delivery to both nasal cavities.

A pivoting joint and perforated cover let naso-gastric tubes pass while keeping the ventilator mask sealed during sputum suction.
