Respirators TRIZ Cases

An annular skirt and gap guide exhalation flow to stabilize pressure, cut turbulence, and reduce ventilator valve whistling.

Heating liquid to form a vapor-column gas spring smooths pump pulsations without bladders, reducing leakage, permeation, and seal swelling.

Heater wire placed on corrugated tube crests keeps breathing gas above dew point, cutting condensation without complex internal heating.

Compartmentalized electrostatic membranes generate CPAP air pressure without bulky compressors, cutting noise, weight, and power use.

An automatic outlet valve opens only when the oxygen conduit is connected, stopping wasteful gas release when disconnected.

A bypass chamber routes upstream exhalation pressure to a sensor port, enabling more accurate PEEP setting than proximal hose measurement.

Patient-specific cardiopulmonary modeling predicts ventilator setting changes to improve oxygenation and CO2 removal while limiting toxicity and barotrauma.

A hydrophilic inner strip draws condensate through the airway conduit wall for evaporation, reducing rainout while preserving pressurized gas flow.

Dual-purpose sensors identify carrier gas and measure mixed flow to improve total anesthetic reporting without a respiratory gas monitor.

A controller tracks heating time and draw count to infer vaporizable substance depletion and adjust power before overheating damages the body.

Miniaturized piezoelectric cantilever valves modulate CPAP airflow in compact arrays, reducing device size, noise, and integration burden.

A retractable sliding bracket secures a humidification unit while allowing extension for access, reducing obstruction, spills, and damage.

A lever-actuated plug expands a flexible ring to seal polymer conduits, enabling aseptic transfer after gamma irradiation.

Pivoting arc-shaped clamps create an adjustable elliptical grip, letting one holder securely fit syringes and respirator tubes of different diameters.

Absolute pressure sensing, gaskets, and sealing features keep vaporizer circuitry and contacts dry for reliable puff detection.

A switched identification circuit detects cartomizer characteristics before heating, preventing incompatible use and stabilizing vapor output.

Dual absolute pressure sensors and targeted sealing improve puff detection while protecting vaporizer circuitry and contacts from liquid exposure.

Load matching and constant current control keep vaporization power stable after medication box replacement, avoiding under- or over-vaporization.

Selective powering of an identification circuit lets the controller verify cartomizer type before heating, preventing incompatible vapor operation.

Absolute pressure sensors, gaskets, and liquid-resistant contacts improve puff detection while preventing liquid ingress, corrosion, and false activation.

A controller reads cartomizer identifier resistance before heating, preventing incompatible vapor units from receiving unsafe power.

A distal microfluidic chip mixes gas and liquid inside a bronchial catheter to improve nebulization and help medication reach lesions with less tissue damage.

Independent gas and liquid inlets in a microfluidic catheter create controlled droplets for lesion delivery while limiting ductal organ damage.

A switched dual-circuit setup identifies cartomiser resistance before heating, blocking incompatible units and controlling battery power safely.

Dual absolute pressure sensing and sealed circuitry help vaporizer devices reject ambient-pressure false puffs and resist liquid damage.

Disposable endovascular electrodes stimulate the phrenic nerve during ICU ventilation to preserve diaphragm function and support earlier weaning.

Absolute pressure sensing, ribbed gasket sealing, and liquid-resistant contacts reduce false puffs and corrosion in vaporizer circuitry.
