APPARATUS AND METHOD FOR SEPARATING AND STORING REPRODUCTIVE MATERIAL IN A CRYOTANK |
摘要 |
Apparatus and method for separating individual human reproductive material from a fertilization dish and storing the material in a cryotank for future fertilization and implantation. The apparatus includes an elongate cryostraw having a first open end and second heat-sealable open end, a channel extending between said ends, and an internal, calibrated volume VC. A displacement bulb is connected to the first end of the cryostraw for admitting and emitting the material into said cryostraw. The bulb has a total volume VB1, an internal cavity with a compressible end volume VB2, a first seal with the first end of said cryostraw; and, means for limiting the intake volume displacement produced in said cryostraw to an amount less than VC no matter how far the bulb is squeezed. The bulb produces less than a unit volume of displacement in the cryostraw when the bulb is squeezed and its volume VB1 is reduced by a unit volume. |
