Multiple exit holes, plenums, diffusers, and fibrous media redirect CPAP vent flow to reduce noise and drafts while maintaining a predictable leak rate.

Silicone at the occipital contact helps stabilize a patient interface, reducing leaks while preserving therapeutic pressure and comfort.

RF sensing tracks bodily movement and respiration variability to distinguish deep, light, and REM sleep without electrical contact.

Lapped panels bonded with adhesive reduce headgear bulk and localized pressure while retaining a respiratory interface during prolonged use.

A smaller middle chamber uses the Venturi effect to limit inhalation leakage and increase exhalation leakage, reducing patient effort.

Segmented chambers and tube arrays isolate blower airflow to reduce noise while preserving compact positive-pressure therapy.

An integrated rail and slide member replaces difficult hook-and-loop adjustment with secure, fine-tuned respiratory headgear fitting.

Hook-and-loop spacer-fabric straps with tailored stretch help stabilize CPAP masks while improving comfort and reducing leaks.

Grooved thickened cheek-contact walls let the nasal seal move locally, reducing nasal bridge pressure while preserving CPAP seal integrity.

Magnetic coupling seals CPAP gas pathways while allowing pivoting separation for faster assembly and flexible component movement.

A dockable ventilator, compressor, and patient interface switch between stationary, extended-range, and stand-alone use to balance mobility and duration.

A pressure port in the nasal prong enables real-time inspiratory-flow feedback to match oxygen delivery to patient demand.

Separate passageways and phase-based flow switching deliver oxygen during inhalation while limiting exhalation losses in respiratory support.

A rotating dial repositions instrument access ports at the mouth or nose, supporting procedures while maintaining adequate oxygenation.

Open-cell foam softens the face contact zone while elastomer fills intermediate cells to preserve mask sealing under positive pressure.

Retained water is heated into vapor by a face mask and chest cover, helping loosen mucus in the sinuses and throat for respiratory relief.

Full-face masks can restrict oral access while cannulas lack pressurization; this apparatus supports both ventilation and end-tidal CO2 sampling.

Condensing medication from exhaled gases, then filtering, sterilizing, and redirecting it, helps reduce waste while sensors measure actual patient uptake.

Color-changing bag indicators help a one-hand resuscitator control tidal volume and ventilation rate without complex electronic sensors.

A geared valve uses rotatable bodies and discrete apertures to regulate compressed gas and air, improving oxygen concentration consistency.

Force and vibration sensors identify mask brand, type, and size at patient-interface connections, improving therapy data and management.

Small-diameter jet ventilation combines efficient PEEP generation with pressure-based mass flow measurement for improved mobility and patient comfort.

Poor fit and leaks in full-face masks are addressed with adjustable strap portions and releasable connections that support comfortable sealing.

A shared oxygen inlet, reservoir, and switching valve shift between free-flow oxygen and bag-assisted resuscitation without changing devices.

An annular strap structure helps keep a nasal mask positioned and gas-tight during extended respiratory treatment.

Gravity weighting keeps the nebulizer nozzle upright, supporting aerosol formation and drug delivery when patients cannot remain seated.

See how a remote control separates operation from the resuscitation device, helping maintain mask position while monitoring the patient.

Periodic high- and low-flow intervals improve aerosol deposition while maintaining respiratory support and oxygen delivery.

Interference and stop bumps stabilize a respiratory mask headgear clip, helping prevent rotation and detachment during use.

Inclined lateral arms keep a flexible nasal cushion raised for a secure nostril seal, reducing leaks during prolonged use.

Threshold-closing valves regulate plenum pressure to reduce discomfort and noise while supporting smoother respiratory therapy transitions.

Twisted, tapered lateral arms spread retaining forces across the face, reducing pressure points and improving mask comfort and fit.

Frictional strap regions help stabilize pediatric nasal cannulas during overnight high-flow, humidified therapy.

Electrical contact mapping identifies heated air delivery tube types so a humidifier can adapt operation to the connected tube.

Sound sensors and cepstrum analysis detect conduit obstructions, recognize accessories, and authenticate users without complex mechanical sensing.

Separate clip positions and adjustable straps let one patient interface switch between nasal and oro-nasal configurations while maintaining therapeutic pressure.

An expiratory flow model estimates missing expiratory characteristics while a vent valve keeps respiratory-interface pressure near its target.

A Venturi jet pump combines ventilator air with oxygen near the patient, bypassing the compressor and avoiding oxygen-pressure safety issues.

Separate strap sections use graded stretchability to accommodate head sizes and improve secure, comfortable respiratory-interface fit.

Automatic end-of-session drying removes moisture from breathing tubing after humidified gas delivery, helping limit condensation and pathogen risk.

A swivable shield and cannula support keep oxygen flowing through a reusable mask while filtration, fit, and cleaning are maintained.
