AI Technical Summary
Technical Problem
In current technology, the assessment of upper airway patency in patients after tracheotomy is often performed through endoscopy, which can easily cause damage to the patient and is cumbersome to operate.
Method used
Design a device for assessing upper airway patency, including a tracheostomy cannula, a connecting tube, a voice-activated one-way valve, and a barometer. The voice-activated one-way valve allows the air inhaled by the patient to be expelled in a separate path, and the barometer detects the expulsion of gas to determine the patency of the upper airway.
Benefits of technology
Upper airway patency can be assessed without endoscopy, reducing patient injury, and the procedure is simple and less painful.

Abstract
The utility model relates to an upper airway patency evaluation device which comprises a tracheostomy cannula, an adapter tube, a voice one-way valve and an air pressure detector, and the tracheostomy cannula comprises a tracheostomy cannula body and an inner air bag. The inner air bag is arranged on the peripheral wall of the tracheostomy tube body and is arranged close to one end of the tracheostomy tube body, the adapter tube comprises a first port, a second port and a third port, the first port is communicated with the other end of the tracheostomy tube body, the voice one-way valve is installed at the second port, and the third port is communicated with the voice one-way valve. The voice one-way valve only allows air to flow into the tracheostomy tube body in a one-way mode, the air pressure detector is communicated with the third port, and the air pressure detector is used for detecting the pressure in the adapter tube. The upper airway patency assessment device can detect and assess patency of the upper airway of a patient without an endoscope, damage to the patient can be reduced, and operation steps are simple.
