Abstract:
1. An on-genital erection device for coital use, the on-genital erection device comprises, under an X-Y-Z Cartesian coordinate system with the direction of an erected penis designated as Z-direction and the penis base plane designated as X-Y plane, a substantially cylindrical elastomeric sleeve surrounding a pre-erection penis upon placement of the sleeve base at a user's penis base, said elastomeric sleeve further comprises at least one through-wall air-ports thereon thereby, after said air-ports get functionally engaged with an external air pumping means, forming an expandable and suctioning air tight enclosure of at least a major portion of the penis surface hence causing a corresponding expansion and erection of the penis for coitus wherein the wall structure of said elastomeric sleeve further comprises a laminate of at least two consecutive layers L i , i=1, 2, . . , M and M>=2, wherein each L i further comprises a pre-defined surface relief pattern RP i thereon such that the corresponding surface relief pattern set RP SET , (RP 1 , RP 2 . . . . RP M ), jointly define a plurality of air paths PT j and externally engageable self-sealing air-ports AP j respectively connected thereto, j=1, 2, . . , N and N>=2, wherein the plurality of air paths PT j further comprises a first air path subset PT sub and a second air path subset PT k and all members of the air path subset PT sub comprising at least one air path PT j that are adapted to pneumatically communicating with at least a major portion of the penis surface thereby, after said air path subset PT sub get functionally engaged, through said air-ports AP j , with an external multi-port air pumping means, forming an expandable and suctioning air tight enclosure of the penis surface hence causing a corresponding expansion and erection of the penis for coitus.
