Abstract
The invention discloses a circulating airflow fertilized-egg suction device for contraception uterus suction, which is a medical instrument for the contraception uterus suction consisting of a double-pipe double-hole pipe, a hat type cervical orifice guider and a balloon type air blowing and suction pump which are integrated into a whole, wherein a simulation operation teaching model for the contraception uterus suction is attached. One is an air blowing pipe in a suction pipe, the other is an air suction pipe, a head of the suction pipe which enters an uterine cavity is provided with an air blowing hole and an air suction hole, the circulating airflow can be blowed into and sucked from the uterine cavity by firmly pressing and loosing a balloon pump, and fertilized eggs can be sucked out of a human body to avoid the impregnation if the fertilized eggs exist. The suction pipe enters a uterus from the hat type cervical orifice guider, which ensures that the contraception uterus suction has simple, safe and reliable use, and small affected risk, thereby the device can be used for families. If a woman has a sex life in the fertile period, the woman only needs to perform one-time contraception uterus suction within 6 to 8 days after the ovulation day, thus the woman does not need to worry about the contraception. If the woman performs one-time contraception uterus suction each month, the woman does not need to take contraceptive medicine and use other contraceptive devices.
Description
Technical field contraception suction circulation airflow oosperm sucking-off apparatus of the present invention is made up of two-tube diplopore germ cell draft tube, hat type cervical orifice guider, gasbag-type air blowing asepwirator pump, and inhales a kind of contraception palace suction medical apparatus and instruments of teaching mode with the contraception palace.
The existing invention of background technology " inhale in the contraception palace " germ cell suction device is with drum type brake cervical orifice guider, the single tube negative-pressure suction catheter that diplopore is arranged with a head, connect vacuum extractor, (the application for a patent for invention number: 2008100373849) of sucking-off germ cell.And germ cell draft tube of the present invention is made up of gas blow pipe, the two-tube unification of suction nozzle, the draft tube head has gas hole and suction hole, afterbody is connected with hand push type (or small electrical dynamic formula) bladder-type air blowing asepwirator pump with two flexible pipes, produce circulating current during use in uterus, it is external with the germ cell sucking-off to be easy to lower negative pressure, the variation of intra-uterine pressure when reducing to practise contraception the palace suction.The present invention has designed hat type cervix uteri mouth guider makes the contraception palace inhale to use simple, safe and reliable, and infection risk is little.Utensil will carry out disinfection before depositing after capable of washing the drying after the use, reusing.Preferably use the disposable sterilization draft tube can avoid unexpected uterine infection etc.
Physiological foundation of the present invention be when women's perception be today ovulation day; or be to ovulate in the future yesterday; if but unprotect the same branch of a family was arranged in the pregnancy period; then just might produce germ cell; and germ cell in the future the 6th～8 day of ovulation in uterus be floating shape, as " seed " of small rice grain size; if not before the implantation, external then just can the avoiding of its sucking-off can be become pregnant in germ cell.Because the draft tube flexible elongated, suction pressure is low, thus the contraception palace inhale no pain, not hemorrhage, infection risk is little.But if had sexual intercourse in the pregnancy period, no matter not fertilization is arranged, the palace suction of once practising contraception then just can vigorously be liked carefree, and the women also need not eat contraceptive.
Summary of the invention the present invention mainly is blow the germ cell draft tube and the hat type cervical orifice introducer of air-breathing two-tube unification.Draft tube be a kind of diplopore of forming with aseptic nontoxic macromolecular material, elongated flexible tube as shown in Figure 1, (1) gas blow pipe among the figure, (2) suction nozzle, (3) gas hole, (4) suction hole, the gas blow pipe joint that airstrainer is arranged (5), the Air suction pipe joint that airstrainer is arranged (6), (7) length scale, (8) draft tube is crooked slightly apart from the about 6.5cm of head place, and (9) draft tube diameter also can be ellipticity less than 4.5mm, (10) draft tube head sealing semicircular in shape, (11) enter the about 6.5cm labelling of cavity of uterus.Rotate the rotatable draft tube of gas joint of draft tube afterbody two sides.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 if the sucking-off of visible tissue thing is the germ cell that is sucked out.
The present invention is for the infection risk in reducing to operate, make the germ cell draft tube not contact the vagina direct convenience, enter cavity of uterus safely, invented hat type cervical orifice introducer as shown in Figure 2, draft tube enters cavity of uterus through hat type orifice of uterus guider, spacing labelling is arranged on the draft tube, make the draft tube head can only enter the about 6.5cm of cavity of uterus, increased processing safety, reliability.(1) cervix uteri head cap among Fig. 2, (2) the identical part of cervix uteri head cap and preceding arched roof, (3) cervix uteri head cap and the identical part of back arched roof, (4) draft tube leadout hole, (5) with the identical curved surface of cervix uteri head, (6) draft tube ingress pipe, the length scale on (7) ingress pipe afterbody can see that guider enters the degree of depth of vagina.
The present invention adopts the air-breathing blower pump of gasbag-type as shown in Figure 3, and two thin film Non-return air valves are arranged in the pump, (1) air bag, (2) air-breathing joint, (3) breather cheek valve, (4) air blowing joint, (5) air blowing check valve.
Description of drawings Fig. 1 is the germ cell draft tube profile of the air-breathing two-tube unification of blowing, and Fig. 2 is a hat type cervical orifice introducer profile, and Fig. 3 is a gasbag-type air blowing asepwirator pump constructed profile, and Fig. 4 inhales simulation teaching model sketch map for the contraception palace.
Embodiments of the invention as shown in Figure 4, Fig. 4 inhales the simulation teaching model for the contraception palace, (1) suction nozzle (germ cell draft tube) among the figure, (2) enter the gas blow pipe head of cavity of uterus, (3) hat type cervical orifice guider, (4) germ cell draft tube delivery line, (5) cavity of uterus, (6) gasbag-type air blowing asepwirator pump, (7) air blowing flexible pipe, (8) inhaling hose.By the study and the simulated operation of contraception palace suction simulation teaching model, medical worker, Mr. and Mrs readily understand the operation that inhale in the process that inhale in the contraception palace and the palace of practising contraception.
The present invention implements easily, industrialization easily, and also use cost is extremely low, has science, practicality, except hospital, health station, is applicable to that more family, Mr. and Mrs carry out " inhale in the contraception palace ", thereby can applies in the whole world.
