Abstract

The invention relates to a free fertilized egg intrauterine inactivation administration suction device, which is a contraceptive appliance with the characteristic that small oval-shaped pills capable of inactivating intrauterine free fertilized eggs are fed into the middle part of a uterine cavity through a pusher, and are pushed into a piston through post tensioning so as to suck free tissues into the pusher. The pusher can be inserted into the middle of the uterine cavity through a petaling cervix uteri mouth importer. The device can be for household use, one-time intrauterine administration suction only needs to be carried out on women having normal sex life within 5-7 days after ovulation date each month, so that the possible free fertilized eggs can be inactivated, implantation is stopped on an endometrium, and pregnancy is avoided. The pusher has a small diameter, is soft and flexible, and can be used for feeding the small pills into the middle part of the uterine cavity directly without dilatating uterus so as to inactivate the free fertilized eggs. Due to the contraceptive method, people can get rid of fear about accidental pregnancy in sexual life, women have no need to use drugs, men have no need to use condoms, and the sexual life is returned to nature.

Description

Free germ cell is inactivation administration suction device in utero

Technical field: the free germ cell of the present invention in utero inactivation administration suction device be a kind of can be with the free deactivated little shape pill of germ cell of intrauterine; Through after pushing device and sending into cavity of uterus middle part; And but post-tensioning pushes piston, attract free tissue substance to get into to push pipe a kind of contraceptive utensil.

Background technology: human up to now in order to prevent accidental pregnancy, adopt oral contraceptive, spermicide, condom, in utero put method such as ring, but the endocrine that not only influences the women that above-mentioned contraceptive device has prolongs menstrual period or increases menses; The separation of having plenty of the both sexes human body causes the psychological obstacle of both sexes; Having plenty of the talent love liquid (seminal fluid and love liquid) that will have antibacterial, keep fit function has discarded or the like.And the present invention does not have the shortcoming of above-mentioned use, is a kind of convenience, safety, the free germ cell inactivation that simply intrauterine possibly existed kills, the contraceptive device of sucking-off, termination implantation.The present invention lets the human sexuality get rid of the fear of worrying accidental pregnancy, lets the sexual life back to nature.

Invention mechanism: the women in ovulation in the future, if there is germ cell to produce, the then germ cell growth that can in uterus dissociate in 5-7 days, or rigidly connect the endometrium entering implantation program of touching.If the big germ cell of Semen setariae during in free state the pill that the grain of rice is big push cavity of uterus, nonoxynolum can be had an effect with germ cell in cavity of uterus, makes its inactivation and dead.The program of possibility terminate self implantation is avoided gestation to endometrium because find the foreign body intrusion of little shape pill is arranged.

Confirming of free phase of germ cell in utero: the women is through study usually, the generation of the perception of can do by myself ovulation day, and promptly vaginal orifice has like the water sample dropping liquid and discharges, but discharges the very fast date that reduces, after can confirming like this to ovulate 5-7 days.Owing to 5-7 days after the ovulation; Cervical mucus gets into the cervix uteri mouth for preventing foreign body; Can become and lose adhesive, be profile of tooth pasty state dope during separation, so through using " germ cell dissociate phase detector " (patent applied for) women can see that cervical mucus is by the drawing-down long filament of the onset of ovulation, seemingly water droplet liquid becomes and is profile of tooth pasty state dope; Can confirm to be free state before in utero being implantation if germ cell existence is arranged.

If sexual life is more, but especially have sexual intercourse in the pregnancy period, then only needed in every month to attract once for the cavity of uterus administration, then the property good fortune is carefree.But if there is not the same branch of a family then can attract without administration in the pregnancy period.So this safe in utero administration attracts contraceptive device both convenient and do not damage health, need not worry for accidental pregnancy again in the sexual life, let the sexual life back to nature.The seminal fluid of human body with like liquid all be the antibacterial of being bestowed by heaven, keep fit, lubricant, bring into play the physical and mental health that its function helps the men and women.

Summary of the invention: the free germ cell of the present invention in utero inactivation administration suction device is that a kind of ellipticity that the grain of rice is big or the little shape of bullet-shaped are killed the ovum pill; Send into cavity of uterus middle part through pushing device, but post-tensioning pushed piston after pill was released, attract free tissue substance to get into a kind of contraceptive utensil that pushes pipe; It is little, soft and pliable and tough to it is characterized in that piston-type pushes the device diameter; Through pushing the spacing ring on the device, make that pushing the device head can only get into the cavity of uterus medium position, in order to be easy to individual, family's operation; Push device and can get into the uterus, and made operational simulation model and teaching picture through petal-shaped cervical orifice introducer.

It is that a kind of ellipticity that medicine such as nonoxynolum and water soluble suppository bases polyvinyl alcohol are formed or the molding glue of bullet-shaped are wrapped up in pill that little shape is killed the ovum pill, and its size is just in time put into and pushed the device head position, is close to push the device piston.

Push the outside oval pipe and the internal piston push rod of device; All adopting medical macromolecular materials to process, is elongated and flexible, and the diameter that pushes device is little; Caliber is about the 3-4 millimeter; Need not expand the palace and just can insert cavity of uterus middle part (as shown in Figure 1), push device appearance restraining position ring block and scale directly into the cervix uteri mouth.Push rod and push and be placed with a spacing latch closure between the device pipe, behind the spacing latch closure of taking away, push rod can be shifted piston onto and push the device oral area, little shape pill is just in time pushed away fall the cavity of uterus middle part.After pill came off, with the piston post-tensioning, then three of head holes (as shown in Figure 3) can be with in the free tissue substance suction tube.

Designed petal cervical orifice introducer in order to be easy to the use of individual and family, introducer is the petal cervix uteri cover (as shown in Figure 4) that a kind of central top is connected with a hollow ingress pipe, and petal can have the 2-6 sheet; Lean on the cover lobe of posterior fornix direction to grow (as shown in Figure 5); Be easy to cervical orifice introducer cover is buckled on the cervix uteri head, the diameter of ingress pipe is about the 6-8 millimeter, and pushing device can be free to slide in ingress pipe; The circular hole of introducer is aimed at cervical orifice; The length of ingress pipe is 12-18 centimetre, and scale is arranged on the ingress pipe, can see the degree of depth that gets into vagina.In order to adapt to cervix uteri in intravaginal position, the exit of ingress pipe is bending slightly.

There is the ingress pipe of the about 6-8 millimeter of internal diameter circular hole at cervical orifice introducer middle part, and its afterbody restraining position ring block makes that pushing tube head can only get into the about 6-7 of cervix uteri centimetre (as shown in Figure 2).In order to adapt to human body difference, petal-shaped cervix uteri mouth introducer has large, medium and small three kinds of specifications.

In order to be easy to use and promote, operational simulation model (as shown in Figure 6) and teaching picture have been made.
