  • Patent number: 5873820
    Abstract: A vaginal speculum comprises two elements (1, 2) having on one hand a spoon part possible to insert in a woman's vagina (3, 5) and on the other hand an oblique handle part (4, 6). After insertion in the vagina, the spoon parts are movable through displacement of the handle parts so that said parts may widen the vagina. There is an aperture of inspection in one handle part (4), the handle parts (4, 6) having co-operating looking means for locking the parts (1, 2) in relation to each other. The upper as well as the lower spoon part (3, 5) have longitudinally curved shape. More precisely, said spoon parts have such a shape that they diverge with at least 30.degree. from concavely curved intermediate portions (17, 17') towards convexly curved portions (18, 18'), the distance between the convexly curved portions (18, 18') being considerably larger than the corresponding distance between the concavely curved portions (17, 17').

  • Patent number: 4973047
    Abstract: A therapeutic device for exercising and stimulating the lung with the aid of a mouthpiece (1) which sealingly co-acts with the lips of the user during the exhalation phase of a breathing cycle. The mouthpiece is connected to a cylindrical, hollow extension (2) and communicates with the surrounding atmosphere through an opening (3) of adjustable area disposed in the extension. The opening (3) is located in the circumference of the extension (2) and the extension is closed-off with the aid of a sealing plug having the function of a valve (4). The valve is rotatable and has a surface which co-acts with the inner surface of the extension, such that the exposed area of the opening (3) can be adjusted by rotation of the valve.
