Abstract
The utility model relates to the field of medical appliances, in particular to a hollow copper bead contraceptive device in which sustained release drugs are stored. The hollow copper bead contraceptive device comprises an outward extended flower core, a bead thread, fixed copper beads and moving copper beads, wherein a dome arch body is arranged in the middle part of the outward extended flower core, and a silica gel protective head is arranged on the outer edge of the outward extended flower core; the bead thread penetrates through the fixed copper beads and the moving copper beads, the two fixed copper beads are respectively arranged on both ends of the bead thread, a plurality of moving copper beads move on the bead thread between the two fixed copper beads, and inner parts of the fixed copper beads and the moving copper beads are hollow; and a plurality of tiny holes are formed in the lower ends of the moving copper beads, and the sustained release drugs are stored in the moving copper beads. The hollow copper bead contraceptive device has the advantages of reasonable structure design and good flexibility, the hollow copper bead structure can automatically deform and adapt under the action of external force, hurt on endometrium is avoided by using the silica gel protective head, pains and discomfortableness caused by inflammation are remitted by the sustained release drugs, the discomfortableness of a user is reduced, and the hollow copper bead contraceptive device is suitable for clinical popularization and application.
Description
Technical field
This utility model relates to medical instruments field, especially a kind of hollow copper pearl birth control apparatus of built-in slow releasing pharmaceutical.
Background technology
Laying intrauterine device is one of contraceptive device the most common in the family planning process, pliability and the hot strength of traditional plastics, silica gel or stainless steel material are not ideal enough, easily cause to uterine mucosa than macrolesion, thereby play pain and hemorrhage, or easily make iud expulsion and pregnancy with IUD in situ takes place.The patent No. is that a kind of copper pearl birth control apparatus of 2253970Y has solved the problems referred to above well, but it has abandoned the use of slow releasing pharmaceutical, can not solve the pain problem that inflammation is brought well, needs further to improve.
The utility model content
The purpose of this utility model is to provide a kind of hollow copper pearl birth control apparatus of built-in slow releasing pharmaceutical in order to overcome above-mentioned technical disadvantages.
The technical scheme that this utility model technical solution problem adopts is: a kind of hollow copper pearl birth control apparatus of built-in slow releasing pharmaceutical, comprise and extend out Hua Xin, the pearl line, fixed copper pearl and the copper pearl that moves about, the described colored core middle part that extends out is provided with vaulted bow body, the outer is provided with silica gel protection head, be equipped with the fixed copper pearl on the described pearl line and the copper pearl that moves about, described fixed copper pearl respectively is provided with one at pearl line two ends, the described copper pearl that moves about is provided with a plurality of, pearl line between two fixed copper pearls moves about, described fixed copper pearl and the equal inner hollow of copper pearl of moving about, the described copper pearl lower end of moving about is provided with a plurality of micropores, and the copper pearl interior reservoir of moving about is equipped with slow releasing pharmaceutical.
Described pearl line is the flexible cord that has toughness, the flexible glue head that described silica gel protection head is made for the medical silica-gel material.
The beneficial effect that this utility model has is: this utility model reasonable in design, hollow copper pearl structure can adapt to from dynamic deformation under external force, pliability is good, silica gel protection head has been avoided endometrial injury, pain and the sense of discomfort brought by slow release agents alleviate inflammation, alleviate the discomfort sensation of user, be suitable for clinical application.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Do following detailed description below in conjunction with 1 pair of this utility model of accompanying drawing.
As shown in Figure 1, this utility model comprises and extends out Hua Xin 1, pearl line 4, fixed copper pearl 5 and the copper pearl 6 that moves about, the described Hua Xin of extending out 1 middle part is provided with vaulted bow body 2, the outer is provided with silica gel protection 3, be equipped with fixed copper pearl 5 and the copper pearl 6 that moves about on the described pearl line 4, described fixed copper pearl 5 respectively is provided with one at pearl line 4 two ends, the described copper pearl 6 that moves about is provided with a plurality of, pearl line 4 between two fixed copper pearls 5 moves about, described fixed copper pearl 5 and the copper pearl 6 equal inner hollow of moving about, described copper pearl 6 lower ends of moving about are provided with a plurality of micropores 7, and copper pearl 6 interior reservoir of moving about are equipped with slow releasing pharmaceutical; Described pearl line 4 is for having the flexible cord of toughness, the flexible glue head that described silica gel protection 3 is made for the medical silica-gel material.During use, extend out Hua Xin 1 and extend out automatically under uterotonic external force effect, adapt to cavity geometry when the copper pearl 6 of moving about is stressed automatically, slow releasing pharmaceutical slowly disengages by the micropore 7 of copper pearl 6 lower ends of moving about.
