Manufacturing method for a hormonal contraceptive tube in which a membrane reservoir is inserted in a holding tube, the reservoir is filled by injection, one end sealed, further filled and then the product polymerized
Fabrication method for a reservoir (5) containing an active substance adapted for introduction into a human body cavity, where the reservoir has a substance-permeable membrane, has the following steps: placing of a tube forming the membrane in a holding device, injecting of the product into one of the tubes open ends, closing of the tube when full at the non-injection end, continued filling until the tube reaches a desired ratio and polymerization of the product within the reservoir when this radius is reached, while holding the reservoir in the holding device. The invention also relates to an installation for fabricating a reservoir for installation in a body cavity.
