Abstract
Abstract A multi-segmented endoscope (20) includes at least two sections (22), (24) which are detachably coupled together to provide endoscopes of varying lengths and openings for use during different stages of the birth process. The end (26) of the smaller section (22) is angled complementarily with respect to the fetus to insure a good seal to prevent contamination of blood samples taken from the infant.

Claim 1
Independent Claim
56 words
An endoscope (20) comprising means defining a hollow, conical cylinder divided into multiple sections (22), (24), each section being detachably connected to (30), (32)-(36) adjacent sections whereby said means provides endoscopes of various lengths and of different size openings (26), (34) for use in engaging a presenting part (16) at different stages in the birth process.
Claim 2
Dependent Claim
56 words
An endoscope (20) comprising means defining a hollow, conical cylinder divided into multiple sections (22), (24), each section being detachably connected to (30), (32)-(36) adjacent sections whereby said means provides endoscopes of various lengths and of different size openings (26), (34) for use in engaging a presenting part (16) at different stages in the birth process.
Claim 3
Dependent Claim
75 words
The endoscope of claim 1 wherein the proximal end (28) of a smaller section (22) and the distal end (34) of the next adjacent larger section (24) are connected together at about 90° with respect to the longitudinal axis of the cylinder whereby said larger section (24) provides an endoscope of shorter length with a larger opening at a complementary angle to the presenting part (16) for use in later stages of the birth process.
