The technology solution of the utility model is as follows:

A kind of novel embryo's suction means, including embryo's suction pipe, plastic flexible pipe and syringe, embryo's suction pipe upper end Ease up washing pipe chamber equipped with an amplification lumen, the both ends of plastic flexible pipe are separately connected buffering lumen and syringe, amplification lumen and Card has one big piston ring and small piston circle respectively in embryo's suction pipe, and a company is connected between big piston ring and small piston circle Bar.

In above-mentioned technical proposal, the amplification luminal surface is equipped with dose calibration.

In above-mentioned technical proposal, it is cased with O-ring respectively on the big piston ring and small piston circle.

In above-mentioned technical proposal, the separator tube is intracavitary to be filled with sponge, and sponge bottom is equipped with a unidirectional thin slice.

The utility model has the beneficial effects that:

The utility model structure is simple, easy to use, and embryo is drawn by syringe, and centre is passed through plastic flexible pipe, put The buffering of big lumen and separator tube chamber to reach the controllability for absorbing embryo's quantity, and is known by the scale of amplification lumen The dosage of absorption, provides convenience for clinical staff.

Detailed description of the invention:

FIG. 1 is a schematic structural view of the utility model；

Specific embodiment:

As described below is only the preferred embodiment of the utility model, is not defined to the scope of the utility model.

Embodiment: as shown in Fig. 1 and Fig. 2, a kind of novel embryo's suction means, including embryo's suction pipe 10, plastic flexible pipe 20 And syringe 30,10 upper end of embryo's suction pipe are equipped with an amplification lumen 101 and separator tube chamber 102, plastic flexible pipe 20 Both ends are separately connected buffering lumen 102 and syringe 30, and amplifying to block respectively in lumen 101 and embryo's suction pipe 10 has a big piston Circle 1011 and small piston circle 1012, are connected with a connecting rod 1013 between big piston ring 1011 and small piston circle 1012.

101 surface of amplification lumen is equipped with dose calibration 1014.

It is cased with O-ring respectively on the big piston ring 1011 and small piston circle 1012.

Sponge 1021 is filled in the buffering lumen 102,1021 bottom of sponge is equipped with a unidirectional thin slice 1022.

Working principle:

A kind of novel embryo's suction means, 10 upper end of embryo's suction pipe are equipped with an amplification lumen 101 and separator tube chamber 102, the both ends of plastic flexible pipe 20 are separately connected buffering lumen 102 and syringe 30, amplify in lumen 101 and embryo's suction pipe 10 and divide Ka there are not one big piston ring 1011 and small piston circle 1012, be connected with one between big piston ring 1011 and small piston circle 1012 Connecting rod 1013, amplification 101 surface of lumen are equipped with dose calibration 1014, are cased with respectively on big piston ring 1011 and small piston circle 1012 O-ring, buffering lumen 102 is interior to be filled with sponge 1021, and 1021 bottom of sponge is equipped with a unidirectional thin slice 1022, passes through syringe 30 draw embryo, centre by sponge 1021 in plastic flexible pipe 20, amplification lumen 101 and separator tube chamber 102 buffering, to reach To the controllability for absorbing embryo's quantity, big piston ring 1011 pulls small piston circle 1012, small piston circle 1012 and embryo by connecting rod Tire contacts, and dose calibration 1013 indicated by big piston ring 1011 is exactly the dosage of embryo, and O-ring guarantees big 1011 He of piston ring The leakproofness of small piston circle 1012；Unidirectional thin slice 1022 can prevent gas from surprisingly flowing back and lead to the impact to embryo.
