Abstract

See full text

A laryngeal mask tube has of a dual-airway tube, a mask with an inflatable bladder and an inflation indicator device. The dual-airway tube has a primary tube communicated with the mask to guide gas into the body of a patient and a secondary tube communicated between with the bladder and the inflation indicator device. Two ribs are formed in the mask to prevent blockage of the primary tube and a tongue is formed inside the bladder to prevent the bladder from folding. Improvements of the laryngeal mask are that the tongue further has an easing hole to reduce rigidity of the tongue and the mask further has a fusing portion to integrally combine the dual-tube and the bladder together to avoid breakage at the bladder. Whereby, the laryngeal mask airway eliminates feelings of discomfort to patients and is durable in use.
