Description
Technical field
The present invention relates to field of medical device, more particularly to one kind subtracts device of tyre.
Background technique
With the utilization of the Assisted Reproductive Technology ARTs such as ovulation induction technology and artificial impregnation, on the one hand for infertility patient with
The hope born children is carried out, multifetation also increases therewith but then.Since multifetation is easy to happen miscarriage, morning
Production, born low birth weight children etc., it is difficult to guarantee that fetus survives, and increase pregnant woman's complication, seriously affect pregnant and lying-in women and tire
The health of youngster even threat to life.The mode that miscarriage is generally taken to multifetation in the past or is developed as one pleases, and in recent years,
With fetal reduction can number that is safe and efficiently controlling delivery of fetus, improve the survival rate of fetus, it is pregnant to greatly reduce polyembryony
The damage being pregnent to mother and baby.
It when carrying out subtracting tire for the pregnant woman of different pregnancy cycles, needs to carry out different operations, often by subtracting tire
Pin puncture heart of fetus ensures that heart of fetus stops after destroying heart of fetus under the auxiliary of medical imaging equipment, to complete
Subtract tire operation, in first half period of gestation, generally subtracts tire needle and puncture by uterine neck and subtract tire, but some fetus periods are larger, need
In the heart of fetus that potassium chloride injection plan is terminated so that it is dead, stay in intrauterine stillborn foetus to mother and its
His fetus does not have adverse effect, but the existing tire needle that subtracts only has puncture function, needs in addition in injection potassium chloride using note
Emitter is injected, this just needs repeatedly to carry out Needle localization, and operation is more complicated, be easy to cause secondary injury to pregnant woman, separately
