Laryngoscope handle and retrofittable insufflation module therefor

An insufflation module for providing insufflation functionality to a laryngoscope said insufflation module comprising:

• a body;
• a jet nozzle extending from said body, said jet nozzle configured and operable to deliver a high velocity stream of gas in a direction substantially along a blade of the laryngoscope such that the gas is deliverable into an intraoral cavity;
• an inlet pipe connector configured to connect said body to a gas delivery pipe;
• a gas inlet via which said gas may be introduced;
• and
• a gas duct extending from said gas inlet to said jet nozzle through the body of the insufflation module, said gas duct comprising a neck portion and a throat portion,
• said neck portion comprising a decreasing cross section tapering towards the throat portion such that when a pressurized gas stream is introduced via the gas inlet the flow-rate of the gas stream increases as the gas stream flows through the duct, and
• said throat portion terminating in a narrow opening of the nozzle such that the gas stream issues from the jet nozzle at a high velocity;
• wherein
• said insufflation module further comprises a laryngoscope-coupling mechanism configured to engage with a corresponding module-coupling mechanism of a laryngoscope such that the insufflation module is securely fastened thereto.
