Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of tracheostomy, especially to a gasbag pressure monitoring device. BACKGROUND

[0002] Tracheotomy is a tracheostomy, and for severe dyspnea before tracheostomy, tracheal intubation is prepared, and if respiratory arrest occurs during tracheal incision, intubation is immediately performed, or intubation is performed before tracheal incision to prevent accidents during the operation. The patient with tracheostomy cuts the trachea in the neck section, and the metal tracheal cannula and the silica gel cannula are put in to solve the problem of laryngeal dyspnea, respiratory dysfunction or respiratory retention caused by lower respiratory tract secretions.

[0003] The artificial airway cuff can not only effectively prevent gas leakage but also prevent and treat patient aspiration. For patients with tracheal intubation or tracheal incision, the gasbag can be inflated to close the airway, which can not only achieve mechanical ventilation but also prevent aspiration caused by subglottic secretions. However, if the gasbag pressure exceeds the perfusion pressure of the tracheal mucosa, it may cause mucosal fibrosis, ulceration, bleeding, tracheal stenosis and even tracheoesophageal leakage. Although high-capacity low-pressure gasbags are widely used in current clinical practice.

[0004] At present, when medical staff treat patients, most of them confirm the air pressure of the air pressure equipment and the air pressure that the patient is currently bearing through touch and visual perception. There is no professional detection equipment, and when the air pressure is high or low, the medical staff can only turn off the air pressure equipment. There is no device that can adjust the output air pressure. This leads to safety hazards for patients during ventilation. UTILITY MODEL CONTENTS
