Description
What magnetic intrauterine device of the present invention related to is a kind of female contraception birth control utensil.
In the nearly 90 years intrauterine device in the whole world (IUD) research, it produces nearly 30 intrauterine device that kind is dissimilar, and particularly nearly 30 years very fast to the research and development of intrauterine device.The intrauterine device that is used at present female contraception both at home and abroad is divided into inertia and two kinds of activity substantially.Inert IUD: domestic representational be rustless steel monocycle, hybrid ring and vinyl contraceptive ring.External for being representative with the polyethylene device, and the U.S. still keeps the unique inertia birth control apparatus that uses at present.The inert IUD stable chemical performance is convenient to sterilization, and is not perishable, can place the long period, do not produce canceration.But weak point is that pregnancy with IUD in situ and band device ectopic pregnancy sickness rate are higher, has side effect such as certain expulsion rate and hemorrhage, pain and infection.Active intrauterine device mainly contains two types: band reactive metal (copper etc.) intrauterine device, medicament slow release intrauterine device.Band copper T-shape intrauterine device, use at present wider, but to the existing side effect of inert IUD such as pregnancy with IUD in situ and ectopic pregnancy, intrauterine infection, hemorrhage, suffering from abdominal pain and coming off etc. does not still have remarkable improvement.The medicament slow release intrauterine device is representative with the levogyrate-18 methyl polysulfide promise ketone intrauterine device, is about to contraceptive and the macromolecular compound that possesses slow release performance, forms as material preparations such as medical grade silicon rubber, polyethylene, and technology is complicated.Its major side effects still for ectopic pregnancy, hemorrhage, pelvic infection, come off and amenorrhea etc.
The purpose of this invention is to provide a kind of magnetic intrauterine device, when keeping intrauterine device to prevent uterine pregnancy well, novel in design unique on the 26S Proteasome Structure and Function, can effectively prevent ectopic pregnancy and intrauterine infection, and side effect such as hemorrhage and pain, decylization are prevented.
Magnetic intrauterine device takes following scheme to realize: magnetic intrauterine device has support, and support can adopt polyethylene (plastics) to make, and support is " doing " font, and support is made of transverse arm, vertical pole.Transverse arm has long transverse arm, hyphen arm, and support top is long transverse arm, and the hyphen arm is in long transverse arm bottom.Vertical pole is a hollow form, and the centre is provided with magnetic devices, and magnetic devices adopts more piece magnetic post group or magnetic bead group to constitute, and can guarantee that vertical pole has certain suppleness, and magnetic field is in low between the magnetic field.Magnetic intrauterine contraceptive is very suitable for uterine cavity shape, the many transverse arms of " fourth " font intrauterine device that uses now play the slip-off preventing effect simultaneously, also increased at intrauterine area simultaneously, for reducing the swing of vertical pole, respectively design a hemispherical projections in its both sides, nearly lower end, also had certain slip-off preventing effect concurrently.There is the nylon tailfiber in vertical pole tail end system, is convenient to follow up a case by regular visits to and take out.Two transverse arms of this utility model intrauterine device adopt flexible plastic, therefore can adopt tubular placement device to insert in the uterine cavity.
Magnetic intrauterine device utilizes antiinflammatory, the anti-infectious function of magnetic field therapy (magnetic therapy), and can prevent and treat uterine cavity effectively and infect and salpingitis, thus prevention and minimizing ectopic pregnancy.Magnetic intrauterine contraceptive utilizes the restriction of magnetic field to unicellular organism motion aspect with flagellum, and the phenomenon (magnetotactic phenomenon) that it is concentrated to magnetic direction, impel sperm (unicellular, having single flagellum) magnetropism intrauterine device field regions concentrates, and stay in the uterine cavity, thereby avoid and reduce sperm and move, reduce quantity that enters sperm in the fallopian tube and the chance that reduces ovum fertilization to reach to fallopian tube.The result had both prevented that gestation from also having prevented ectopic pregnancy.The present invention on material and planform for preventing pain, hemorrhage and come off and all done special design.All adopt flexible plastic as two transverse arms, adopt the more piece small magnetic rod in the vertical pole, to keep vertical pole certain suppleness is arranged, so that it is hemorrhage with friction to adapt to the unlikely generation pain of uterine contraction face.Simultaneously vertical pole tail end two sides have increased by two hemisphere projections, can avoid vertical pole swing by a relatively large margin, and the transverse arm two ends all are designed to pure garden shape in addition, thereby can reduce transverse arm to the pressure of palace wall on every side, prevent and embed palace wall phenomenon.Magnetic intrauterine contraceptive is Duoed a transverse arm than general T type intrauterine device, thereby takes off resistance under having increased, and reaches to prevent the purpose that comes off.This intrauterine device can be placed with the cast placement device, and because of tailfiber is arranged, it is also convenient to observe and take out.Magnetic intrauterine device is provided with magnetic devices, because the advantage of magnetic material is nontoxic, safety, no absolute contraindication, so magnetic material has been widely used in medical treatment (magnetic therapy).In adopting clinically, the low-intensity magnetic fields topial treatment of disease also proves that to the body not damaged magnetic field intensity can be adjusted to adapt to different crowd, can adopt permanent-magnet alloy to keep long-term magnetic intensity constant to the life-time service person.Handle can do demagnetization because of special requirement person, the intrauterine device after the demagnetization still has the contraception function.The present invention is because of there being the magnetic alloy material, thus the clinical lonizing radiation that can utilize conduct a survey, with determine to have or not come off and the position normally whether.The magnetic intrauterine device technological design is novel succinct, easily manufactured, economical and practical, in population control research and family planning work broad prospect of application is arranged.
The invention will be further described below with reference to accompanying drawing.
Fig. 1 is the magnetic intrauterine device structural representation.
Has support with reference to accompanying drawing magnetic intrauterine device structure, support is " doing " font support, support is by transverse arm, vertical pole 3 constitutes, transverse arm comprises long transverse arm 1, hyphen arm 2, long transverse arm is on support top, hyphen arm 2 is in long transverse arm 1 bottom, vertical pole 3 is a hollow form in mid-stent, and magnetic devices 4 is equipped with in the centre, adopts more piece magnetic post group or magnetic bead group to constitute, can adopt the short magnetic of 5 joints to form, can guarantee that vertical pole has certain pliability, magnetic devices can adopt the rare earth cobalt alloy material to make inner core, and magnetic intensity is 400～500GS, magnetic field intensity is divided into six grades in the magnetic therapy, promptly extremely a little less than, a little less than, low, in, by force, extremely strong magnetic field.Intrauterine device of the present invention magnetic field is between low, middle magnetic field.Vertical pole 3 nearly both sides, lower end respectively have hemispherical projections 5, can reduce the swing of vertical pole.The vertical pole tail end is processed with tailfiber hole 6, and in the tailfiber hole being has tailfiber 7, and tailfiber adopts nylon yarn to make, and is convenient to anti-and taking-up.
