A DEVICE FOR PREVENTING INVOLUNTARY URINATION, PREFERABLE FOR FEMALES

摘要

A device for preventing involuntary urination, preferably in females comprises an oblong mainly rod-shaped body (1) with one or more diameter increasing enlargements (2, 3) and with an interior conduit (4) leading to the proximal end of the rod-shaped body and serving to receive a pin (5) for use in inserting the device into the urethra. The rod-shaped body (1) is resiliently deformable lengthwise, and the diameter increasing enlargements (2, 3) which may comprise one or more bellows-shaped portions (2) and/or transverse lamellae, are resiliently deformable so that, when the rod-shaped body has been brought into an extended insertion condition by means of the insertion pin (2, 28), they are deformed to a decreased outer diameter permitting effortless insertion into the urethra with little irritation to the tissue, whereas in a contracted condition of the rod-shaped body attained after retraction of the pin (5, 28), they can assume an increased diameter so as to come into sealing contact against the surrounding tissue of the urethra.
