Abstract: Transferring devices provided by the invention substantially improve efficacy of vacuum erection systems. Added to the system, the transferring device enables to dislodge one, two or more constrictors instantly. The external transferring device for penile constrictor comprises a pulling loop 4 attached to a mounting tube 22. An embodiment with the mounting tube inserted into the vacuum chamber (internal transferring device) is designated for vacuum chambers with abdominal air tight seal and for chambers with removably placed penile seal. An embodiment with a mounting tube 22 placed over the vacuum chamber 12 (external transferring device) is designated for vacuum erection systems with permanently inserted penile seal 14. Proposed transferring device can be easy retrofitted by the user into the existing system, without the need for special tools or skills. A method for transferring penile constrictors from the vacuum chamber onto erect penis has been proposed.

Abstract: Erection control system of the invention overcomes known deficiencies of vacuum constriction devices, especially cumbersomness, technical difficulties and painfulness.A penis-shaped vacuum chamber (12) adapted for unnoticeable operation under user's cloth. Removably placed penile seal (14) and a baffle (16) are adjustable to the user's penile girth and provide attachment so that the vacuum chamber hangs on the user's penis without additional support.A ribbon-shaped constriction device (26) is wound with multiple turns over each other to form a cylindrical ring, retained by the belt (28) for exerting a prearranged inward radial pressure. A transferring device with the pulling loop (40) dislodges constriction device together with removably placed penile seal and baffle onto erect penis with simultaneous release of vacuum without additional mechanisms. The removably placed penile seal, the baffle, the belt are formed from segments of a condom.
