Description
Technical field
The present invention relates to a kind of intrauterine device, specifically a kind of center of gravity transfer type intrauterine device.
Background technique
Intrauterine device is a kind of contraception device being placed in uterine cavity, generates foreign matter to uterine cavity inner wall by contraceptive
Stimulation, causes the aseptic inflammation in uterus, makes embryo that can not become pregnant in the normal implantation of intrauterine to achieve the purpose that contraception, this
Contraceptive method little effect on the human body has the advantages that safe and reliable, long-acting.Effective time after existing intrauterine device placement
Longest is possible to later up to 10-15, more than certain time can be due to susceptibility of the cavity inner wall to the contraceptive reduces
Contraceptive effect is lost, due to each one system difference, people can not judge when cavity inner wall can be right after intrauterine device is placed
The contraceptive loses susceptibility, and only generation unwanted pregnancy Shi Caihui learns that contraceptive fails, therefore at present on the market in utero
Contraceptive product is required to replace in user 5-10, and user is needing repeatedly to receive to place in life, taking out birth control
The operation of device, and bear the pain and psychological pressure of operation bring physiologically.
Summary of the invention
The object of the present invention is to provide a kind of center of gravity transfer type intrauterine devices, it can be in user's daily life
Postural change shift the center of gravity of contraceptive at any time, contraceptive itself can slightly shake in center of gravity transfer process, give palace always
Cavity wall applies different foreign matter stimulations, so that uterine cavity inner wall is remained sensitive to contraceptive, contraceptive effect can run through user
Whole life cycle.
The present invention to achieve the above object, is achieved through the following technical solutions: including annular hollow shell, outside annular hollow
Toroidal cavity is formed inside shell, fixed ring is arranged in border on the outside of toroidal cavity, and multiple rectangular recess, each square is arranged in fixed ring inner wall
Connected in star is uniformly distributed along fixed ring inner wall border, and tungsten ball is arranged in toroidal cavity, and tungsten ball can freely move in toroidal cavity
Dynamic, the radius of tungsten ball is 2-3 times of rectangular recess width.2 tungsten balls are set in toroidal cavity.The annular hollow shell is by two
A shape, size annular semicircle groove profile shell all the same are welded to each other composition.Locating slot is arranged in annular hollow outer casing inner wall, Gu
Determine ring outer wall setting locating piece, locating slot is matched with locating piece, makes fixed ring will not the rotation of opposed annular hollow shell.
The present invention has the advantages that contraceptive can be shifted at any time with the postural change in user's daily life
Center of gravity, contraceptive itself can slightly shake in center of gravity transfer process, and applying different foreign matters to uterine cavity inner wall always stimulates, and make palace
Cavity wall remains sensitive to contraceptive, and contraceptive efficacy can run through user's whole life cycle, avoids user from bearing anti-
The multiple pain placed, take out contraceptive operation and pressure etc..
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the portion I enlarged structure schematic diagram in Fig. 1；
Fig. 3 is the A-A section view enlarged structure schematic diagram of Fig. 1.
Specific embodiment
A kind of center of gravity transfer type intrauterine device of the present invention includes annular hollow shell 1, in annular hollow shell 1
Portion forms toroidal cavity 2, and fixed ring 3 is arranged in 2 outside border of toroidal cavity, and multiple rectangular recess 7 are arranged in 3 inner wall of fixed ring, respectively
Rectangular recess 7 is uniformly distributed along 3 inner wall border of fixed ring, tungsten ball 4 is arranged in toroidal cavity 2, tungsten ball 4 can be in toroidal cavity 2
It inside moves freely, the radius of tungsten ball 4 is 2-3 times of 7 width of rectangular recess.The annular hollow shell 1 is hollow structure, with it
Internal tungsten ball 4 compared to self weight compared with light, volume is larger, and tungsten ball 4 small volume, weight compared with annular hollow shell 1 it is larger,
Therefore the center of gravity of this contraceptive is concentrated near tungsten ball 4, when tungsten ball 4 moves in the toroidal cavity 2 in annular hollow shell 1
When dynamic, the position of centre of gravity of this contraceptive can be changed correspondingly.After this contraceptive is placed in the uterine cavity of user, with using
Postural change in person's daily life, tungsten ball 4 can move under the effect of gravity, to shift the center of gravity of contraceptive at any time, make uterine cavity
Inner wall can receive different foreign matter stimulations, contact always with 3 inner wall of fixed ring in 4 moving process of tungsten ball, repeatedly into and out of fixation
The rectangular recess 7 of 3 inner wall of ring.The radius of tungsten ball 4 is that 2-3 times of 7 width of rectangular recess can ensure that the only sub-fraction energy of tungsten ball 4
Enough enter rectangular recess 7, prevents tungsten ball 4 from being blocked by rectangular recess 7.Tungsten ball 4 is contacted with the edge of rectangular recess 7 can make contraceptive
Slight vibration occurs, this vibration can occur when user changes position with the movement of tungsten ball 4, make contraceptive to palace
Cavity wall generates additional stimulation, and uterine cavity inner wall is made to remain sensitive to contraceptive.Above structure can make birth control of the invention
Effect runs through user's whole life cycle, and user is avoided to bear to place, take out the pain and pressure of contraceptive operation repeatedly.
The present invention can be arranged 2 to further enhance the stimulation that contraceptive generates uterine cavity inner wall in toroidal cavity 2
Tungsten ball 4.When user changes position, 2 tungsten balls 4 can be moved and mutually be collided, and uterine cavity inner wall is promoted to keep quick to contraceptive
Sense.
Following structures can be used for the ease of production and processing in the present invention: the annular hollow shell 1 is by two shapes, big
Small annular semicircle groove profile shell all the same is welded to each other composition.Two annular semicircle groove profile shells in the structure can be used one
Mold processing advantageously reduces production cost, simplifies production stage.
The present invention moves together in order to avoid fixed ring 3 and tungsten ball 4, locating slot can be arranged in 1 inner wall of annular hollow shell
5, locating piece 6 is arranged in 3 outer wall of fixed ring, and locating slot 5 is matched with locating piece 6, makes fixed ring 3 will not opposed annular hollow shell
1 rotation.
