CONTAINER FOR OOCYTE FERTILIZATION AND REPLACEMENT OF EMBRYOS IN MAN AND ANIMALS

摘要

P THIS INVENTION CONCERNS A CONTAINER FOR FERTILIZING OOCYTES AND REPLACING EMBRYOS, IN THE ABSENCE OF AIR ENRICHED IN CO, THAT CAN BE EFFECTED IN UTERINE CAVITY, IN TRUMPES OR IN STOVE. THE CONTAINER CAN TAKE THE FORM OF A LOW DIAMETER 1 STRAW, ONE OF THE END OF WHICH CAN BE OPENED OR CLOSED BY A BIODEGRADABLE PLUG 2, THE OTHER END BORGNE 3 ALSO CLOSED BY A SEALED PLUG, OR MAY CONTAIN A SYSTEM OF FILTRATION OF SPERMATOZOIDS, SUBSTANCES OR MICROFILTERS RETENTED DURING REPLACEMENT BY REDUCING THE OPEN END OF THE STRAW 12. THE END BORGNE IS EXTENDED BY A SLEEVE 5 WHICH ALLOWS TO FIX A SYRINGE TO SEE OOCYTES AND SPERMATOZOIDS OR A CHUCK WHICH WILL PUSH THE PLUG 4 WHEN REPLACING EMBRYONIC. THE SURFACE OF THE SLEEVE SHOWS SMALL ASPERITIES 6 TO MAINTAIN THE STRAW THROUGH A HANDLE DURING MANIPULATIONS. THE SLEEVE IS SURMONED WITH A SCREW 7 ON WHICH CAN MOVE A MOLLETTE 8 WHICH, PUSHING A MOBILE RING 9 ON WHICH ARE FIXED TABS 10, INDUCES THEIR DEFORMATION, THE OTHER END OF THE TABS BEING FIXED BY THE INTERMEDIATE OF A SOLDERED RING ON THE STRAW 11. DEFORMATION OF THE TABS ALLOWS TO IMMOBILIZE THE STRAIN IN THE UTERINE CAVITY. THIS SYSTEM CAN BE REPLACED BY A SMALL BALLOON THAT IS SWAPPED ON. GREATER SIMPLIFICATION MAY BE USED BY USING BIODEGRADABLE CAPSULES IN WHICH THE OVOCYTES AND SPERMATOZOIDS NECESSARY FOR FERTILIZATION ARE PLACED, WITH DELITIZATION CARRIED OUT WITHIN THE TIME REQUIRED FOR THE EMBRYOS TO BE DIRECTLY INTO THE UTERINE CAVITY FOR THEIR IMPLANTATION. / P THESE DEVICES THEREFORE ENABLE THE FERTILIZATION OF HUMAN OR ANIMAL OOCYTES IN ABSENCE OF AIR ENRICHED IN CO AND DISPENSING FROM A DELICATE PHASE OF THE CLASSIC IN VITRO FERMENTATION THAT IS THE EMBRYONIC REPLACEMENT. / P
