Apparatus for oocyte recovery includes a hand held unit 2 for selectively connecting a recovery needle (1 fig 1) to sources of flushing liquid or suction, an oocyte receptacle 35 and means to manually select between flushing and supply of oocytes. Receptacle 35 may be evacuated to supply a source of suction for aspiration of oocytes and sealed with a cap 38 to be pierced by a spike connector 33. Alternatively a vacuum pump (50' fig 4) may draw the oocytes into the receptacle. Flushing liquid may be supplied from a remote container (3 fig 1) via supply line 4 or from a container (3' fig 4) within the unit, the container may be pressurised. The means to select between flushing and supply of oocytes may be switches (26 and 32 fig 2) controlling valves 25 and 31. The needle may be a dual lumen needle. |
