Abstract: A device for removing lice and nits from affected hair and scalp of an individual, has first and second movable blades, the first blade including a plurality of first saw teeth, the second blade including a plurality of second saw teeth, and means for movably retaining the first and second blades parallel and adjacent to one another with their respective first and second teeth in opposition and parallel planes along their respective longitudinal axes, whereby the blades can be selectively moved toward one another to cause their teeth to mesh together with hairs captively held therebetween, the first and second teeth being configured to thereafter provide via combing a scraping action against the entrapped hairs for removing lice and nits therefrom.

Abstract: A comb for removing lice and nits from the hair is formed by a base and a plurality of teeth extending from said base in substantially the same direction. The longitudinal axis of each tooth is parallel to the longitudinal axis of each other tooth. Each tooth has a polygonal cross sectional shape as in the form of a triangle. The cross sectional dimensions of each tooth enlarge from the free end of each tooth toward the base so that the spacing between adjacent teeth narrows toward the base. The facing edges of adjacent teeth interact with each other to capture, in a scissor-like manner, lice and nits therebetween.

The longitudinal axis of each tooth is parallel to the longitudinal axis of each other tooth. Each tooth has a polygonal cross section shape such as in the form of a diamond. The cross sectional dimensions of each tooth enlarge from the free end of each tooth toward the base so that the spacing between adjacent teeth narrows toward the base. The facing edges of adjacent teeth interact with each other to capture, in a scissor-like manner, lice and nits therebetween.
