Abstract
The invention relates to an O-shaped contraceptive ring which adopts a metal material as an annular inner support and is externally alternately sheathed with a metal tube and a macromolecular polymer tube. The contraceptive ring has the advantages that an open space can enable the metal (copper, silver and the like) tube to be thickened and enlarged, so that long-term contraception effectiveness is improved; the metal inner support is closed into an annular shape, firmness is improved, and the metal inner support hardly comes away, so that safety is improved; drug can be mixed in the macromolecular polymer, so that a skeleton type slow-release formulation is formed, first-order pharmaceutical release is realized, sustained release drug delivery is realized by virtue of a mucosa, and side effects such as pain and bleeding in an initial stage that the contraceptive ring is placed are reduced; meanwhile, weight is light, so that acceptability is improved; and the contraceptive ring can be conveniently placed and taken out.
Description
Technical field
The present invention relates to a kind of intrauterine device, it is adaptable to family planning field.
Background technology
Since the 50-60 age in 20th century, intrauterine device, as a kind of long-acting reversible pregnant control measure, is widely used.Variously-shaped birth control apparatus is developed successively.Application comparison has O shape, T-shaped, Y shape etc. widely.Wherein O and many variant thereof, is to invent morning, application time length, applicable crowd's product widely；To such an extent as to people the most still get used to intrauterine device to be referred to as intrauterine device.Conventional O is substantially manufactured by bi-material, and one is macromolecular material, and one is metal material.The advantage that macromolecular material injection manufactures is easily manufactured, good biocompatibility, and corrosion resistance is strong, and shortcoming is the most ageing-resistant under human body environment, and easily become fragile fracture；The birth control apparatus of this material has exited market successively.The O of metal material, the close winding spring that relatively representational rustless steel is made, machinery overlap joint makes the ring-type of Guan Bi end to end.It is improved to the most again in bourdon tube load copper wire spring and pastille adhesive tape.This O manufacturing process is simple, low cost, puts and takes conveniently, and side reaction is little, and acceptable strong, shortcoming is that lap-joint easily disengages end to end, it is easy to cause vulneratio uteri, simultaneously narrow space in bourdon tube, limits the loading amount of copper and medicine, affects long-term contraception effect.
Summary of the invention
The present invention relates to the annular inner support of a kind of metal material, the outside O shape intrauterine device that alternately set metal pipe and polymer pipe are made.Have an advantage in that: open space can make metal tube (such as copper or silver etc.) thicken increase, improves long-term contraception effectiveness；Internal metal rack circularizes through closing, and firmness improves, and is difficult to disengage, improves safety；Medicine can be mixed with so that it is become matrix type slow release formulation, it is achieved medicine first-order release in high molecular polymer, through mucous membrane sustained-release administration, alleviate the side reaction such as hemorrhage grade of band initial stage pain, simultaneously because weight considerably reduces, improve acceptability；Put and take the most conveniently.
The present invention has the further advantage that material is easy to get, cheap, is simple to manufacture, easily realizes batch production.
Accompanying drawing explanation
A kind of intrauterine device of Fig. 1 is the O shape of Guan Bi；Set metal pipe and polymer pipe is replaced outside ring support.
Fig. 1 is structural representation, is only used for the explanation citing of a kind of intrauterine device and is not intended to its range of structures.
In Fig. 1,1 is metal tube, and 2 is metal material inner support, and 3 is polymer pipe or the medicament slow release preparation made for carrier with it.
Detailed description of the invention
The concrete technology step that described a kind of intrauterine device manufactures is as follows.
A, prepare elastic support.
The elastic support of given shape is made with metal material.
The preferred niti-shaped memorial alloy of described metal material and stainless steel silk material.
B, prepare polymer pipe, the preferred silicone rubber of described high molecular polymer, it is also possible to be the medicament slow release preparation made for carrier with it, cut to suitable length.
C, prepare metal tube (including serpentine pipe), the preferred copper of described metal and silver, it is also possible to be its alloy, cut to suitable length.
D, will cut after polymer pipe and metal tube alternately set install on support, then by support termination close, pack rear sterilizing, obtain product.
Claims (5)
1. a ring support for metal, the outside O shape intrauterine device that alternately set metal pipe and polymer pipe are made, it is characterised in that: its metal rack closure state ringwise, it replaces set metal pipe and polymer pipe.
A kind of intrauterine device the most according to claim 1; it is characterized in that: its metal rack closure state ringwise; its annular can be annulus; can also be the approximation D-ring of annulus, crescent ring, triangular loop, uterine cavity shaped ring etc.; as long as in closure state, i.e. within this claim is protected.
3. according to a kind of intrauterine device described in claim 1 and 2, it is characterised in that: its support length of run is in 200 millimeters, and its cross-sectional area is in 3 square millimeters.
A kind of intrauterine device the most according to claim 1, it is characterised in that: metal tube (including metallic coil) the surface area sum of suit on it, in the range of 400 square millimeters.
A kind of intrauterine device the most according to claim 1, it is characterised in that: it on, the polymer pipe of suit can be simple substance, it is also possible to being the sustained-release and controlled release preparation made with certain medicament mixed of high molecular polymer, its quality sum is within 3 grams.
