| The ground element is a thin tube (diameter 4 - 6 mm) with two rows of thin boreholes. |
| The right (distal or body-apart) row of holes would be covered with a gum ring and makes a kind of a valve. |
| The whole tube, or at least all the area of holes, is covered with a thin membran tube, wherein the both ends of it are permanently stuck with the tube. |
| A thin bag, a kind of mini condom, three or five times longer than the tube and closed at its distal end, made of latex or polyuretan, is put into the tube so that it comes upon the area of proximal row of the holes, being not-permanently stucked to the tube, so that the holes are insulated. |
| At the open end of the bag a vacuum appears. The bag folds up accordion-like going into the tube. |
| At the distal end of the tube there is a syringe installed there. The radially directed nozzles of the syringe are directed towards the distal holes of the tube. |
| An outer wrapper is attached to the whole device, and the wrapper, in apart, ensures the sterility. The open end of the wrinkled bag is overturned and not-permanently stucked upon the proximal end of the out-cover. |
| With that is the contraceptive device finished and ready to be used. It is here represented in the natural size. |
| The above-mentioned construction is admittedly possible, but it could be a bit too expensive in the process of production. Therefore there is an alternative, which could result, in tests, as a suitable one. There are just three elements in it: a lens-like or droplet-like tube, an inside small bag and an inserting stick. The urethra is no pipe, but a closed body opening, which extends just in the moment of inserting, having enfolded the new body. There will be shown in the tests if a press-room is necessary. |
