A laryngeal mask tube consisting of dual-airway tube 10, a mask 20 with an inflatable bladder 24 and an inflation indicator device 30. The dual-airway tube 10 comprises a simplified primary tube 12 and secondary tube 14 integrally combined together. The primary tube 12 communicates with the mask 20 to guide gas into the body of a patient. The secondary tube 14 communicates with the bladder 24 and the inflation indicator device 30 to monitor the pressure within and inflate the bladder 24. Moreover, at least one rib 26 is formed in the mask to prevent blockage of the primary tube 12. A tongue 242 is formed inside the bladder 24 to prevent the bladder 24 from folding and preventing a seal around the larynx. |
