Abstract

A ventilatory laryngoscope with disposable laryngoscope lens including: a laryngoscope handle and a laryngoscope lens that is connected with an extension arm of the handle; transparent lens protecting cover on the end of the lens cavity; oxygen injecting through-hole on the cover; oxygen supply pipe in seal plug connection with the through-hole, the other end connected with an oxygen source pipe; scrubbing nozzle on the cover, and a drug delivery pipe. The laryngoscope has advantages: during the trachea intubation, ventilation and oxygen supply may be achieved in the body to effectively prevent cerebral anoxia and prolong the safe time limit of the intubation, improve the success rate of cardio-pulmonary resuscitation, and provide a safe and reliable guarantee; improve intubation safety and reduce professional risk; the secreta may be removed from the cover to achieve timely rescue of critically ill patients by collecting clear glottis image and smoothly completing the intubation.
