Abstract
The invention discloses a fertilized egg suction device for contraception uterus suction, which consists of a cervical orifice guider, a fertilized egg suction tube, and a negative pressure suction apparatus, wherein a simulation operation teaching model is attached. The suction tube enters a uterus through the cervical orifice guider, both sides of a round head are provided with two suction holes, and the suction holes, through the negative pressure in the suction tube, suck fertilized eggs which float in the uterus and are not implanted out of a human body within 6 to 8 days after the ovulation day further to avoid the impregnation. The device can be used for hospitals and families; the device has convenient use and simple operation; during the use, a female has no pain and no bleeding, and the device does not affect the health of the female. A woman who has a sex life in the fertile period can not get pregnant after one-time contraception uterus suction, and the contraception uterus suction is reproductive health care of contraception. After a female at the reproductive age senses the ovulation day every time, the female performs one-time contraception uterus suction within 6th to 8th days, does not need to worry about the accidental pregnancy in the sex life, and does not need to take contraceptive medicine and use contraceptive devices again, thereby contributing to the sex life, the family planning and the reproductive health.
Description
Technical field oosperm sucking-off apparatus for contraception of the present invention is by the cervical orifice guider, the teaching mode composition is inhaled in germ cell suction catheter, vacuum extractor and contraception palace, the germ cell sucking-off from the uterus that is a kind of not implantation is external, avoids the medical apparatus and instruments of pregnant women.
The existing women of background technology carries out very early pregnancy artificial abortion, be behind the germ cell implantation, again that pregnant lens capsule tissue sucking-off is external in 35～50 days pregnancy periods, to expand the palace in the operation, have pain, hemorrhage, the damage women healthy reproduction and Mental Health.And the present invention is in women's ovulation 6～8 days in the future, germ cell enter the uterus be afloat, as yet not before the implantation, the germ cell sucking-off is external, so the sucking-off process is painless, not hemorrhage, and owing to soft, elongated disposable suction catheter transcervical mouth guider enter the uterus, do not contact vagina, so the process of attraction infection risk is minimum, the softish suction catheter of round end can only enter the about 6.5cm in uterus and just in time touch or do not touch uterus cavity bottom simultaneously, so safety is good.
Physiological foundation of the present invention is, according to existing technology, the women is by the study natural family planning, use the fertility tests device (patent No.: ZL01116767X inventor: Xue Dade) or urine examination, or the body temperature method etc., the women can perception ovulation day or perception be yesterday ovulation day, but if in the pregnancy period, have sexual intercourse, then after ovulation, carry out once " contraception palace inhale " in the 6th～8 day, if any the small rice grain size, in cavity of uterus, be floating state, the germ cell of implantation will not be sucked out external as yet.Along with the development of technology, by the urine test of human chorionic gonadotropin (HCG), can know the generation of germ cell earlier, the feasible palace of practising contraception is inhaled and is shot the arrow at the target especially, can avoid carrying out blind suction.But because the present invention is simple to operate, use cost is extremely low, do not have pain, no hemorrhage, do not damage the uterus, have no side effect, infection risk is little, so after but the pregnancy period has sexual intercourse, (blind suction: inhale no matter there is not germ cell existence all not carry out a palace), generation and the worry that can exempt accidental pregnancy are inhaled in the palace of once practising contraception.Select the every month palace of once practising contraception to inhale if know the inside story, then can exempt accident all one's life and obtain pregnant worry, help sexual life and Mental Health.
Summary of the invention the present invention mainly is the diplopore germ cell suction catheter of cervical orifice guider and flexible elongated.The cervical orifice guider as shown in Figure 1, circular guider rearview, guider cutaway view are arranged among the figure, the moulding of the leading section of guider can match with intravaginal cervix uteri head, (1) is the curved surface of the intravaginal cervix uteri head that coincide among the figure, (2) be the curved surface that coincide with the back arched roof, (3) suction catheter leadout hole, (4) suction catheter imports slotted eye, (5) the length scale on the cylinder can see that guider enters the degree of depth of vagina.
The germ cell suction catheter that the present invention is connected with vacuum extractor as shown in Figure 2, (1) rounded nose among the figure, (2) preceding attraction hole, (3) back attracts hole, (4) length scale, (5) end into spacing, suction catheter can only enter the about 6.5cm in uterus, and (6) sliding piece (being used to rotate suction catheter) has the negative pressure gas joint of airstrainer in (7), connect negative pressure generator, (8) can be less than 30 ° of bendings.After the suction catheter slotted eye of suction catheter in cervix uteri mouth guider imports the uterus, open negative pressure, suction catheter upper and lower, left and right in cavity of uterus are moved, sweep and take out suction catheter again after inhaling for several times, in suction catheter,, be the germ cell that is sucked out as if the sucking-off of visible tissue thing.
Description of drawings Fig. 1 is cervical orifice guider rearview, cutaway view, and Fig. 2 is a germ cell suction catheter cutaway view, and Fig. 3 inhales the teaching mode sketch map for the contraception palace.
The embodiment of the invention as shown in Figure 3, teaching mode is inhaled in the contraception palace, (1) germ cell suction catheter among the figure, (2) enter the draft tube head of cavity of uterus, (3) cervical orifice guider, (4) cavity of uterus, (5) negative pressure trachea.It is to be used for the medical worker and Mr. and Mrs carry out simulation learning and operation that teaching mode is inhaled in the contraception palace, makes the present invention can enter hospital, family planning station and family and uses.
Because the women uterus leans forward, normally, hypsokinesis, the difference of size so that the cervical orifice guider can be made plurality of specifications is selective, enters the about 6.5cm of cavity of uterus but suction catheter can only protrude leadout hole, makes the contraception palace inhale to operate safer.
