Submergible laryngoscope with handle fluid sealing means

In a fluid submersible laryngoscope including a hollow handle containing power supply means, a blade to be inserted into a patient's mouth, light transmitting means carried by the blade, and means to removably attach the blade to an end portion of the handle in a substantially L-shaped configuration, the improvement comprising:

• (a) a light source with a reflector carried by the handle at said handle end portion, for movement relative to the handle and power supply means,
• (b) means to place the light source in electrically energizing relation with the power supply means when the blade is attached to the handle to displace the light source relatively toward the power supply means, whereby light is directed into said light transmitting means carried by the handle,
• (c) and fluid sealing means blocking access of external fluid into the hollow handle proximate the light source and reflector, whether or not the blade is attached to the handle, and whether or not the handle is submerged in fluid,
• (d) said fluid sealing means extending outwardly at said end portion of the handle to be contacted by the blade when the blade is attached to the handle,
• (e) said fluid sealing means including resiliently compressible material to be compressed by the blade when the light source is displaced relatively toward said power supply means.
