摘要:
A laryngoscope comprising a handle and a blade is provided. The blade is hingedly articulated to the handle between an open position wherein it projects outwardly from a top end of the handle, and a closed position wherein it lies in registration therewith. The laryngoscope further comprises an electric light source and a power source selectively electrically connected thereto for providing electric power for its operation. The blade comprises a power source compartment at the proximal end, containing therewithin the power source. The laryngoscope further comprises a switching arrangement configured to electrically connect between the electric light and power sources when the blade in its open position, and electrically separate between the electric light source and power source when the blade in its closed position. The handle comprises a depression for accommodating therein at least a portion of the blade when in its closed position.

A laryngoscope handle is provided. The laryngoscope handle comprises a lower grip and an upper functional portion comprising a blade-retention portion formed with a slot extending in a longitudinal direction parallel to a viewing axis, and being configured for slidingly receiving therewithin a laryngoscope blade, and a light source disposed above the slot and being directed substantially parallel to the viewing axis. A majority of the area above the slot and surrounding the light source is substantially free of visual obstructions along the viewing axis.

A ventilator-resuscitator device comprising a mixing chamber, a compressor, a controllable pressure-relief vent, and a controller, is provided. The mixing chamber has air and oxygen inlets, and an outlet. The compressor is configured to operate crate at two or more power levels and to increase, by a different amount at each power level, the pressure of a gas flowing between a low-pressure side thereof and a high-pressure side thereof, thereby producing a pressurized gas, the low-pressure side being in fluid communication with the outlet of the mixing chamber. The vent comprises an orifice configured to bring the high-pressure side of the compressor into fluid communication with the atmosphere. The controller is configured to direct operation thereof and to regulate the pressure of the pressurized gas by selectively operating the compressor at one of its power levels.

A laryngoscope handle has a lower grip and an upper functional portion comprising a blade-retention portion formed with a slot extending in a longitudinal direction parallel to a viewing axis, and being configured for slidingly receiving therewithin a laryngoscope blade, and a module-coupling mechanism. An insufflation module may include a body; a jet nozzle extending from the body, the 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.
