An endotracheal intubation tube capable of automatically monitoring air bag pressure

Abstract

The invention discloses a trachea cannula capable of monitoring air bag pressure automatically. The trachea cannula is made of antibacterial materials integrally. The tip portion of a patient end of the trachea cannula is formed by flexible body materials, namely soft PVC (polyvinyl chloride), a thin-film pressure sensor is mounted on the inner wall of an inflatable cuff, an air bag pressure monitor is connected to an inflating tube through a three-way tube, a Bluetooth module is mounted in each of the thin-film pressure sensor and the air bag pressure monitor, and the thin-film pressure sensor and the air bag pressure monitor are wirelessly communicated with a mobile terminal through the Bluetooth modules. The trachea cannula capable of monitoring the air bag pressure automatically has the advantages that the tip portion is made of the soft PVC material coated with antibacterial coatings internally and externally, so that inappropriate compression of the patient end on tissues of a human body is avoided during use of the trachea cannula, damage to human organ mucosae is reduced, and related infectious complications during tracheal catheter indwelling can be reduced; since the thin-film pressure sensor and the air bag pressure monitor are used for detecting the air bag pressure in real time, use safety is improved; the mobile terminal can obtain pressure detection data in real time.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a tracheal intubation tube capable of automatically monitoring the pressure of an air bag. Background technique [0002] Endotracheal intubation is suitable for establishing an artificial airway for patients in clinical practice, performing mechanical ventilation, surgical anesthesia, or cardiopulmonary resuscitation. The inflation size and stability of the air bag on the endotracheal tube determine whether the respiratory function support technique is successful. Endotracheal intubation and tightness of the patient's airway are key to positive pressure ventilation on the ventilator and prevention of aspiration of oropharyngeal secretions. Excessive inflation of the airbag will compress the tracheal tissue and cause ulcers or rupture of the airbag. Insufficient inflation will cause air leakage and affect the work of the ventilator or aspiration. At present, when most medical pe...

AI Technical Summary

Problems solved by technology

And some patients have poor cardiopulmonary function and a lot of respiratory secretions, which will prolong the indwelling time

It is also possible to take a neck tracheotomy and intubation so that the indwelling time can be longer, but this operation is traumatic and difficult to care for

Although endotracheal intubation initially solved the difficulty of ventilation and facilitated suction of foreign matter such as sputum and blood in the airway. After intubation, the airway mucosa will be oppressed, rubbed, irritated, etc., which is very likely to cause intubation complications, resulting in the failure of the catheter indwelling and having to be extubated, terminating the treatment
