DEFINITION

Classification: 604/48

Treating material introduced into or removed from body orifice, or inserted or removed subcutaneously other than by diffusing through skin:

(under subclass 19) Subject matter wherein a body treating material is placed into or removed from a body opening, or is placed under the external membraneous tissue covering the body or removed therefrom other than by being applied to the skin and permeating therethrough.

(1) Note. Insertion of material under an eyelid is not considered as insertion into body.

(2) Note. Conduits which are provided with plural outlet apertures are not considered to be sprayers when placed in a body orifice since the wall of the conduit contacts the wall of the orifice which prevents the spraying function. However, if such a conduit is provided with a guard spaced outwardly from the wall of the conduit so that fluid issues form a plurality of apertures formed in the conduit, then the arrangement permits spraying even when the conduit is inserted in a body orifice because the guard keeps the conduit spaced from the wall of the body orifice, and such sprayers are classified in Class 128 in appropriate subclasses.
