Mother cell is sucked in oocytes collection vessel by extracting flexible pipe.
As preferred：The negative pressure joint uses quality of rubber materials.Using above structure, it is to avoid at work occur gas leakage and
Have a strong impact on procedure efficiency.
As preferred：The sealing-plug uses transparent plastic material.Using above structure, it is easy to observe the unobstructed of feed liquor
Whether.
As preferred：Needle stand is installed away from one end of runner in the infusion tube.Using above structure, it is easy to connection
Needle tubing, injects liquid.
Compared with prior art, the beneficial effects of the utility model are：
The two-chamber oocyte collector provided using the utility model, structure is novel, it is easy to accomplish, prevent the liquid of injection
The egg mother cell refunds ovary that body will be remained in the main channel of puncture needle, effectively increases the collecting efficiency of egg mother cell, shortens
Operating time, so that reduce the dosage of the sedative or anesthetic used patient, while reducing anesthetic risks,
Enable the patient to faster recover normal mobility.
