ABSTRACT OF THE DISCLOSURE A speculum is formed of a stiffly flexible plastic material and com- prises two members. Each member has an elongated blade with a convex outer surface. In one embodiment, the top member is in the form of an integral hinge fixedly interconnected with a second member with the blade- like portion forming the front leaf. The hinge is flexible to provide a pivotal movement of the two blades about the hinge axis. In another form of the speculum, the top member has a pair of sockets formed therein adapted to receive a pair of assembly pins which are integral with the bottom member of the speculum. A constricted portion is formed in each pin to permit flexure and thereby to form a "living" hinge which permits the pivotable operation of the speculum. In still another embodiment, both blades and the interconnecting pins are integrally formed of a material having sufficient flexure to function as a "living" hinge.
