Abstract
The magnetic intrauterine device is an elastic uterine-shaped ring made of helically-wound stainless steel wire, and in its helical cavity at least two rare earth permanent magnets with coppered external surface are placed, and the correspondent ends of two adjacent magnets are mutually-folding polarity, and the stainless steel wire adopts non-magnetic or less-magnetic material. Said invention can form magnetic field with proper field strength in the uterine cavity, and can release a small quantity of copper ion so as to raise the contraceptive effect. The magnetic field also can produce two-way regulating action on human body, so that it possesses the health-care physiotherapeutic effect for some woman diaseases.
Description
The invention belongs to a kind of women's of being used for the interior contraceptive of official jargon.
At present, the intrauterine device of clinical practice is various in style.With the rustless steel coiling to include medicine and little copper spirochetal for best.This structure is fetched and delivered conveniently, is in utero placing stablely, and harmless, contraceptive effect is good.Abroad had about containing the report of magnetic intrauterine contraceptive loop: the birth control apparatus as United States Patent (USP) U.S patent patant namber 4727866 data of patent Mar 1 1988 these patent disclosures is placed with magnetic ball, purpose is that magnetic signal is provided when getting, be convenient to judge the position of ring at uterine cavity, more than two kinds of birth control apparatus, there is not physiotheraping effect, and the common problem of actual clinical birth control apparatus existence at present is to make band device person that sense of discomfort is arranged, sometimes it is hemorrhage to produce uterine cavity, symptoms such as pain in the lumbar region are extensive use of thereby limited intrauterine device.
The object of the invention is to disclose a kind of magnetic intrauterine contraceptive, produces magnetic effect in official jargon, in the hope of producing two-ways regulation with body, produces untoward reaction after avoiding being with device, and attempts that some chronic diseases of gynecological are had medical care effect.
Below with reference to embodiment technical scheme is described:
Fig. 1 is a front view of the present invention.
Fig. 2 is Fig. 1 partial enlarged drawing.
Basic design of the present invention is to increase magnetic effect for it on the basis of existing rustless steel palace shape birth control apparatus.This utility model is a kind of elasticity uterus shape contraceptive ring 1 of few magnetic stainless steel silk helically coiling, in the helical cavity of ring, be placed with the rare-earth permanent magnet 2 of two or more copper coatings, per two its magnetic polarities of adjacent magnets corresponding end can be to roll over polarity mutually, and described stainless steel silk is for few magnetic or do not have the magnetic material.Fig. 1-2 places a Magnet for the inherent centrage tip of most preferred embodiment uterus shape contraceptive ring of the present invention place, place two magnets in lower end centrage lateral symmetry, be bikini shown in Figure 1, the close coiling pipe of stainless steel silk closed hoop, make Nickel Plating Treatment after selecting for use few magnetic J rustless steel to be shaped, permanent magnet is neodymium, ferrum, boron rare-earth permanent magnet, has than high-intensity magnetic field, and its termination portion magnetic density can reach 300 (B.
Adopt stainless steel silk to make palace shape helical ring, after the shaping, and do chromium plating and handle, its stable chemical performance, corrosion-resistant, the person that can reduce the band to greatest extent is because the discomfort reaction that intrauterine device produced.The rare-earth permanent magnet magnetic core, volume is little, magnetic field intensity is big, adopts no magnetic or few magnetic stainless steel silk, does not produce magnetic cup and keeps away, can form the above field intensity of 300GS in magnet ends, in utero producing magnetic effect, magnetic field produces dual regulation to human body, the copper facing of magnetic core outer surface, discharge small quantity of copper ion in vivo, can improve contraceptive effect.The present invention can reduce band device person and produce sense of discomfort, and one or two people are in utero hemorrhage owing to being with device to take place, and untoward reaction such as pain in the lumbar region have therapeuticing and health effect to some chronic gynaecological diseases.
Claims (2)
1, a kind of magnetic intrauterine contraceptive, it is the elasticity uterus shape contraceptive ring (1) that becomes with the stainless steel silk helically coiling, it is characterized in that: be placed with the rare-earth permanent magnet (2) of the copper coating more than two or three in the helical cavity of described ring, described stainless steel silk is for few magnetic or do not have the magnetic material.
2, magnetic intrauterine contraceptive according to claim 1 is characterized in that: described stainless steel silk is the few magnetic rustless steel of J, and described rare-earth permanent magnet is neodymium, ferrum, boron permanent magnet, and quantity is three, with palace shape centrage symmetric arrangement.
