Video blade laryngoscope

摘要

A laryngoscope (200) including a control circuit (202) that is detachably connectable to a handle (204), where the control circuit functions and is compatible with a wide variety of displays. The laryngoscope may optionally be used in either the video mode where the user views a display presenting image data of the area ahead of the blade (206), or the user may use the laryngoscope in the direct visualization where the user uses the laryngoscope in a traditional manner directly viewing the area ahead of the blade during the intubation procedure. A digital imaging device (260) and an illumination device (LED) are contained in a sleeve (214) detachably coupled to the blade. When used in the video mode, the LED is positioned adjacent to a window (264) enclosing the digital image sensor to defog the window.
