Technical Field
The utility model relates to the technical field of laryngeal masks, in particular to a laryngeal mask with good sealing performance.
Background
The laryngeal mask is a special artificial airway management technology, is developed successfully in the middle of the 80 s and is used for clinic and introduced in the domestic 90 s. The use of laryngeal masks has greatly advanced and has become increasingly widely used. The ventilation mask at the front end of the laryngeal mask is elliptical and can wrap the epiglottis and the glottis to form a sealed ventilation space on the glottis. The patient can breathe spontaneously through the laryngeal mask and ventilation can be controlled. After the laryngeal mask is placed, whether the laryngeal mask is positioned correctly can be judged by means of auscultation, airway resistance, PETCO2 waveforms, gastric tube (double-tube laryngeal mask) placement and other methods.
If the sealing effect is poor, flatulence can be caused during positive pressure ventilation; air leakage easily occurs when airway pressure is too high (e.g., when the pneumoperitoneum causes the diaphragm to rise in laparoscopic surgery); poor stability and easy displacement; the laryngeal mask can not completely avoid reflux aspiration for patients who do not strictly forbidden water; the oral secretion is more. The main reason that current laryngeal mask leakproofness is not good is that it has only an inflatable bag usually, and the laryngeal mask is put into patient's throat back and is inflated the inflatable bag and make the laryngeal mask fixed and the inflatable bag still plays the effect of sealed human throat simultaneously, but in the operation, the inflatable bag is because its with the throat laminating pressure not big and the position has factors such as adjustment, easily takes place the inflatable bag and the throat laminating is not tight produces the not good problem of above-mentioned sealed effect.
