Description

A kind of laryngeal mask with local anesthesia function

technical field

The utility model relates to a laryngeal mask, in particular to a laryngeal mask with local anesthesia function.

Background technique

The function of the laryngeal mask is to maintain the breathing of an unconscious patient such as a patient under general anesthesia, and to establish a breathing passage for the patient. The ventilation mode of the laryngeal mask is different from that of the trachea. It belongs to the supraglottic ventilation. No other auxiliary equipment is required during intubation, and it will not damage the oral cavity, teeth, trachea, vocal cords and other tissues. It has played a major role in rescuing patients and surgical anesthesia. After the operation, the patient enters the recovery period. At this time, it is not easy to perform local anesthesia on the patient's throat again. Therefore, the patient who is inserted into the laryngeal mask will have uncomfortable reactions such as choking and coughing due to the stimulation of the throat during the recovery period. The incidence of cardiovascular adverse events increases, the incidence of nausea and vomiting increases, and the satisfaction rate decreases, which affects the treatment effect, and there are certain safety risks.

Detailed ways

The present utility model will be further described below with reference to specific embodiments and accompanying drawings.

Example 1

As shown in Figures 1 to 3, a laryngeal mask with local anesthesia function includes a curved laryngeal mask ventilation tube 1. The upper end of the laryngeal mask ventilation tube 1 is provided with a detachable joint 2, which is convenient for connecting to an air source. The lower end of the laryngeal mask ventilation tube 1 is connected with a laryngeal mask airbag 3 , and the laryngeal mask airbag 3 is connected with an airbag inflator, and the airbag inflator is used to inflate the laryngeal mask airbag 3 . The airbag inflation device includes an airbag inflation tube 4 , one end of the airbag inflation tube 4 is connected to the laryngeal mask airbag 3 , and the other end is connected to a one-way inflation valve 5 . A local anesthetic catheter 7 is fixed in the airbag cavity 6 of the laryngeal mask airbag 3 , and the local anesthetic catheter 7 is fixed on the inner wall surface of the skin contact surface 8 of the laryngeal mask airbag 3 .
