Speculum with color filter

摘要

A speculum includes a body portion of generally cylindrical shape having a distal end for insertion into a body cavity, and a proximal end from which internal body tissues may be examined. A handle extends laterally from the proximal end of the speculum body. A light source providing broad spectrum white light may be supported within the handle. A light channel extends along and through the speculum body to direct light from the light source in the handle toward the distal end of the speculum body in order to illuminate the body cavity. One or more color filters are selectively disposed between the light source and the light channel to selectively illuminate the body cavity with light of a corresponding color spectrum.

主权项

1. A speculum comprising in combination:
a. a generally cylindrical body, the generally cylindrical body including an open distal end for insertion into a body cavity and an opposing open proximal end through which an internal tissue area may be examined, the generally cylindrical body having a generally cylindrical hollow passageway extending therethrough; b. a handle coupled to the proximal end of the generally cylindrical body, the handle extending generally laterally from the generally cylindrical body; c. a light source receivable within the handle for providing broad spectrum white light; d. a light channel which extends along the generally cylindrical body to direct light from the light source toward the distal end of the generally cylindrical body in order to illuminate the body cavity; e. a first color filter selectively insertable within a space located between the light source and the light channel to selectively illuminate the body cavity with light of a first color spectrum.
