Abstract: A device for prevention of involuntary urination in a female has an elastic body (21) designed for arrangement in the vagina for compressive action on and support of the neck of the bladder. The body (21) is made of a compressible material and comprises at least two projecting legs (23) joined in a flexible base (22) and is dimensioned in such a way that in the non-deformed state of the body of the longest distance between the free ends of at least two legs exceeds the distance between the anterior wall and the posterior wall of the vagina. After the insertion of the body into the vagina in an elastically deformed stated with the legs bent in a direction towards each other, an active pressure is thus exerted on the bladder neck. On their mutually facing sides, the legs are designed in such a way that in the elastically deformed insertion state they come into mutual contact for the provision of an increased elastic force of restitution.
