An improvement of a fluid submersible laryngoscope including a hollow handle to contain power supply means and a blade to be inserted into a patient's mouth includes a terminal pin carried on an end portion of the handle by a tubular elastomeric body and an insulation disc located between the power supply means and the end of the elastomeric body. The elastomeric body acts as a fluid sealing means to block access of external fluid into the hollow handle whether or not the blade is attached to the handle. The insulation disc defines a bore through which the terminal pin at least partially extends such that attachment of the blade to the handle will cause the terminal pin to move through the bore and contact the power supply means.
