Surface grooves wick condensation to heated regions for evaporation, preventing rainout and preserving gas flow and humidity in breathing circuits.

A gas-jet exhalation detector mechanically shifts airway pressure, enabling portable disposable bi-level support without sensors or batteries.

Flexible engagement arms and a tightening strap keep a softened, wet ETT securely connected to the ventilator and prevent disengagement.

A pressure-biased actuator adjusts the valve flow path to keep PEEP stable despite leaks, flow variation, and auto-PEEP risk.

A hinged teeth-and-groove grip secures neonatal endotracheal tubes while limiting adhesive skin contact and reducing unplanned extubation.

A supplementary heater-plate signal detects low water from thermal response, reducing sensor count and working across changing flow rates.

A compliant heater plate and single thermistor detect low-water conditions from thermal response, avoiding extra flow sensors in medical humidifiers.

A rotary valve switches positive and negative pressure flow to add therapy oscillations that improve secretion removal during airway clearance.

Integrated heating wires and simplified fittings keep respiratory gases above dew point, preventing pooling and reducing assembly errors.

A supplementary power waveform and compliant insulation sheet let a humidifier heater plate detect low water from thermal changes using one sensor.

A rotating ball and membrane valve switches inspiratory or expiratory occlusion while preventing expulsion during coughing and aiding secretion control.

A fixed-volume flushing unit clears mucus and debris from a pulmonary catheter lumen to preserve accurate airflow monitoring during lung assessment.

Hard plastic inserts reinforce soft tracheostomy tube flange openings to resist tie damage while reducing separation and inhalation risk.

Bite-force sensing on an endotracheal tube enables continuous detection of agitation and self-extubation attempts with fewer false alarms.

A normally open, low-profile tracheostoma valve uses a pressable sealing member to redirect exhaled air for speech while staying simple and discreet.
