A low cost camera and light emitting diode are coupled to the distal end of an endotracheal tube to obtain an image in real time of tissue at the distal end of the endotracheal tube. Power for the light emitting diode and camera, along with a signal reflective of the image captured by the camera, are transmitted through electrical conductors embedded in the wall of the endotracheal tube and are coupled with a plug. The plug is detachably attached to a radio frequency transmitter module to provide electrical power to the light emitting diode and to the camera and for transmitting the signal of the captured image to a receiver for real time display of the image on a video monitor. |
