Abstract
Abstract A medical instrument is provided with a chemiluminescent light source for inspection and examination of a body. The light source comprises at least two compartments separated by a barrier, each compartment filled with a suitable fluorescing component, such that by breaking the barrier between the compartments and causing admixing of the components, a chemical reaction occurs which produces the chemiluminescent effect In a particular embodiment of the present invention, an endoscopic instrument such as a vaginal speculum, is provided having cooperating upper and lower dilator blades pivotally connected to each other, a means associated with at least one dilator blade for releasably engaging thereto a chemiluminescent light source adapted to direct its light intermediate the dilator blades in their spaced apart position to illuminate the body cavity being examined.

Claim 8
Dependent Claim
57 words
A light according to claim 6, wherein means for mechanically securing the light to the instrument comprises means allowing the light to be snap-fitted between upstanding ribs on the instrument, means allowing the light to be slidably fitted within flanges on the instrument or a sleeve that can be fitted over an elongate portion of the instrument
Claim 9
Dependent Claim
63 words
A medical instrument including an examination light, comprising : a) a medical instrument body adapted to receive a light source; and b) a chemiluminescent light source attached to said medical instrument, said light source comprising a light transmitting body adapted to fit adjacent a contoured surface of said medical instrument body and provided with attachment means for attachment to said medical instrument body.
Claim 10
Dependent Claim
63 words
A medical instrument including an examination light, comprising : a) a medical instrument body adapted to receive a light source; and b) a chemiluminescent light source attached to said medical instrument, said light source comprising a light transmitting body adapted to fit adjacent a contoured surface of said medical instrument body and provided with attachment means for attachment to said medical instrument body.
Claim 11
Dependent Claim
25 words
