Respirators TRIZ Cases

A spring-driven transmission adjusts the winding ratio as the drum diameter increases, keeping the used blister strip taut and preventing loop formation.

Third-order polynomial calculations generate customizable pressure transition profiles between inhalation and exhalation phases in bi-level therapy devices.

A dual-locking mechanism secures an anesthetic evaporator to the anesthesia main machine using a primary mechanical and secondary electronic lock.

Adhesive nasal device uses a flap valve airflow resistor to inhibit exhalation more than inhalation, treating respiratory conditions.

Control device segments electrode signals to extract ECG data while suppressing interference, enabling accurate EMG-based breathing effort detection.

A ventilator computer adjusts pressure and ventilation rates using real-time volume flow and carbon dioxide sensor data.

Fourier transform of airway flow yields the H1/DC ratio, replacing invasive catheters with automated spectral detection to reduce respiratory muscle fatigue.

Capillary-based oral aroma sampling device eliminates carry-over effects and satiety during high-throughput flavor evaluation.

A ventilator self-test derives tubing compliance coefficients to estimate and compensate for circuit volume loss during patient ventilation.

A piezoelectric droplet delivery device generates sub-5 μm aerosol streams for precise pulmonary administration.

A compact patient valve with an angular connection design reduces internal dead space volume for efficient gas delivery.

A respiratory treatment device adjusts CPAP pressure using real-time blood glucose sensor data to manage metabolic levels during sleep.

Gesture-based touch screen interface resolves device complexity versus ease of operation trade-offs in clinical breathing apparatuses.

Porous tobacco carrier saturates with fluid to release nicotine uniformly, preventing overheating and pyrolysis during aerosol generation.

Inhaled argon postconditioning during CPR reduces reperfusion injury and improves survival rates after cardiac arrest.

Elastomeric oral appliance prevents soft palate collapse while improving user acceptance by reducing device intrusiveness.

A ventilator adjusts ventilation parameters based on real-time physiological measurements to maintain optimal patient support.

Thermal conduction between chambers volatilizes drugs into aerosols, reducing hepatic metabolism and improving patient convenience.

A whole-body hyperthermia system uses isolated heating and fluid circuits to stabilize patient temperature.
