Chamber；Threeway handle includes that threeway handle suction cavity and threeway handle rinse chamber, and the of syringe needle suction cavity and threeway handle suction cavity
The connection of one interface, syringe needle rinses chamber to be connect with the first interface that threeway handle rinses chamber, therefore takes ovum process and flushing process can
To carry out simultaneously, the time of ova harvest is shortened；Suction port protrudes from the first end face of test tube plug, negative pressure mouth and is depressed in examination
The ovum of the first end face of pipe close, taking-up is smoothly fallen into ovum receiving flask from suction port, and the ovum of taking-up will not be in negative pressure mouth
High vacuum region sucked by negative pressure suction device, reduce test tube plug first end face occur negative pressure vortex phenomenon；In ovum
During entering ovum receiving flask from suction port, due to suction port be provided with the second port of export-oriented angular cut and suction tube with
The suction port junction of test tube plug is provided with suction port contraction flow region, and the probability that splash occurs for ovum can be effectively reduced, and reduces ovum
Son guarantees the ovum quality taken out from suction port to the impact in ovum receiving flask whole process；The inner cavity shape of suction port
For standard Luer inner circle cone, therefore the probability blocked during suction tube is collected is reduced, and in suction tube generation
It is easy to connect syringe in suction port inner chamber body so as to cleaning and dredging in the case where blocking, reduces because attracting blockage to cause to take ovum
Operation is interrupted or the probability of failure.
To sum up, double-cavity ovum taking needle provided by the utility model, by optimizing the syringe needle of double-cavity ovum taking needle and the structure of handle,
And suction port to test tube plug and negative pressure mouth improve, inhaled during ova harvest ovum and flushing process can simultaneously into
Row, substantially increases and takes ovum success rate and ovum survival rate, shorten the time of ova harvest.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
