Problems solved by technology

[0002] The laryngeal mask is a supraglottic ventilation device that can meet the needs of most general anesthesia operations, but it is not as accurate as the endotracheal tube. For example, when the prone position, body position changes, or the laryngeal mask is not well sealed, the laryngeal mask can be replaced with an endotracheal tube. Necessity, but this replacement adds greater inconvenience
Furthermore, the inserted endotracheal tube stimulates the trachea and glottis, which is extremely uncomfortable during the recovery period of the patient, and can cause severe coughing, increased blood pressure, and even high abdominal pressure, wound dehiscence and other symptoms

Abstract

The invention discloses a laryngeal mask with a retractable tracheal tube, which comprises a cup, a tracheal tube and a retractable mechanism; wherein an airbag is provided on the contour edge of the cup, and the cup extends to a side away from the airbag There is a connecting part; the tracheal tube is movably worn in the cup, and the tracheal tube is provided with a cuff; one end of the retractable mechanism is connected with the inner wall of the connecting part, and the other end of the retractable mechanism is connected with the outer wall of the tracheal tube, The retractable mechanism is retractable on either side of the two sides at the connection position of the retractable mechanism and the connecting portion. The laryngeal mask with the retractable tracheal tube provided by the invention realizes the integration of the laryngeal mask and the tracheal tube, and can realize the rapid switching between the laryngeal mask and the tracheal tube in the pharyngeal cavity of the patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a laryngeal mask with a retractable tracheal tube. Background technique [0002] The laryngeal mask is a supraglottic ventilation device that can meet the needs of most general anesthesia operations, but it is not as accurate as a tracheal tube. Necessity, but this replacement adds greater inconvenience. In addition, the inserted tracheal tube stimulates the trachea and glottis, which is extremely uncomfortable during the patient's recovery period, and can cause severe coughing, increased blood pressure, and even high abdominal pressure, wound dehiscence and other symptoms. In order to overcome the above-mentioned medical difficulties, it is necessary to develop a new integrated airway management tool combining a laryngeal mask and a tracheal tube. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a laryngeal mask with a retractable ...
