Abstract
Abstract A fluid submersible laryngoscope (10) (Figure 1) includes a hollow handle (11) to contain power supply dry cell batteries (54). A terminal pin (37) is carried by the handle (11) and a conductor (50) is provided to place that pin (37) in electrical energy transmitting relation with a light bulb (25) carried by a blade (12) removably attachable to the handle (11), the blade (12) being insertible into a patient's mouth to illuminate the throat area. Sealing structure (57) is provided between the terminal pin (37) and handle (11) to block access of external fluid into the hollow handle, whether or not the blade (12) is attached to the handle, and when the handle is submerged in fluid.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
A fluid submersible laryngoscope or the like including a hollow handle to contain power supply means, a blade to be inserted e.g. into a patient's mouth, and means to removably attach the blade to an end portion of the handle in a substantially L-shaped configuration, characterized by a) a terminal pin carried by the handle at said end portion of the handle, b) means to place the terminal pin in electrical energy transmitting relation with a light bulb carried by the blade, when the blade is attached to the handle, c) and first fluid sealing means between the terminal pin and handle to block access of external fluid into the hollow handle, whether or not the blade is attached to the handle, and when the handle is submerged in fluid.
Claim 2
Dependent Claim
130 words
A fluid submersible laryngoscope or the like including a hollow handle to contain power supply means, a blade to be inserted e.g. into a patient's mouth, and means to removably attach the blade to an end portion of the handle in a substantially L-shaped configuration, characterized by a) a terminal pin carried by the handle at said end portion of the handle, b) means to place the terminal pin in electrical energy transmitting relation with a light bulb carried by the blade, when the blade is attached to the handle, c) and first fluid sealing means between the terminal pin and handle to block access of external fluid into the hollow handle, whether or not the blade is attached to the handle, and when the handle is submerged in fluid.
Claim 3
Dependent Claim
57 words
An instrument as claimed in claim 1, wherein said fluid sealing means comprises a tubular elastomeric body carrying said terminal pin, the pin having a shank in fluid sealing relation with a bore defined by said elastomeric body, said body having an exterior generally annular surface in fluid sealing engagement with a bore defined by the handle.
Claim 4
Dependent Claim
37 words
An instrument as claimed in claim 2 including an end closure attached to an end of said body remote from the terminal pin, said closure providing one current passing connection between the power source and said pin.
Claim 5
Dependent Claim
52 words
An instrument as claimed in claim 3 including a compression spring extending between said end closure and said pin to provide an electrical current path therebetween, and within said tubular elastomeric body, the body being compressible to resiliently transmit force for improved contact of the pin with a surface on the blade.
Claim 6
Dependent Claim
20 words
An instrument as claimed in claim 2, 3 or 4 wherein said body surface and handle bore have threaded interconnection.
Claim 7
Dependent Claim
29 words
An instrument as claimed in claim 5 including a synthetic resinous sleeve extending about said pin shank and compressed between said shank and the bore of said elastomeric body.
Claim 8
Dependent Claim
44 words
An instrument as claimed in any preceding claim including an end cap removably attached to the end of the handle, remote from the blade, and second fluid sealing means between the cap and handle to block access of external fluid into the hollow handle.
Claim 9
Dependent Claim
26 words
8 . An instrument as claimed in claim 7 wherein the handle and cap are metallic, and said second fluid sealing means comprises an elastomeric 0-ring.
Claim 10
Dependent Claim
23 words
An instrument as claimed in any preceding claim wherein the blade consists of a synthetic resinous material and has a bite flange thereon.
Claim 11
Dependent Claim
24 words
An instrument as claimed in any preceding claim wherein the bulb is carried by the blade near the end thereof remote from the handle.
