  • Disposable vaginal speculum
    Patent number: 4766887
    Abstract: A two-piece vaginal speculum has upper and lower blade members pivotally connected to each other by a slot and pin arrangement for relative pivotal and spatial adjustment of the blade members. Slots are formed in the sides of the upper blade member, and trunnions with lugs directed outwardly through the slots are formed on the sides of the lower blade member. Cheek plates in the upper blade member sides have ribs formed therein for selective engagement with teeth formed on cheek plates of the lower blade member sides. The ribs extend in the direction generally parallel to the slots, and achieve sliding engagement with the teeth so that the position of the trunnion lugs can be moved from one to another set of notches formed on the slots. The teeth and rib have engaging surfaces which are back angled at about seven degrees so that compressive forces of the patient's vaginal wall on the blades will urge the rib and the engaging tooth, and their supporting cheek plates, into engagement.

  • Razor with handle to store a blade unit or cartridge
    Patent number: 4182031
    Abstract: The razor is of the type which has on its head a generally T-shaped fitting on which a conventional razor blade unit can be releasably mounted by urging the fitting into a correspondingly shaped channel or recess formed in the back of the blade unit. The blade unit can be removed from the head and stored in a generally rectangularly-shaped aperture formed through the razor handle intermediate its ends. An elongate rib is formed on one side wall of the aperture, and a cam lug is formed on the other side wall so that when the blade unit is forced into the opening the cam lug urges the channel of the blade unit releasably over the rib, thereby positively to hold the blade unit in the handle until forced therefrom by finger pressure or the like.
