Description
技术领域technical field
本实用新型涉及避孕装置，尤其涉及一种放置于宫颈上的避孕装置。The utility model relates to a contraceptive device, in particular to a contraceptive device placed on the cervix.
背景技术Background technique
目前使用比较广泛的放置于宫腔内的避孕装置有吉妮环、曼月乐环、惰性金属环、含CU环、含药的环等，也称为宫内节育器。吉妮环由一根手术线和6个小铜管组成，呈长条形状，利用放置器可将其置入子宫顶肌层深处。它的作用机制与其它含铜宫内节育器一样，使宫内膜产生异物反应，不利于受精卵着床；同时它释放的铜离子还干扰精子的运动，并起到杀伤精子的作用。At present, the widely used contraceptive devices placed in the uterine cavity include Genie ring, Mirena ring, inert metal ring, CU ring, drug-containing ring, etc., also known as intrauterine devices. The Genie ring consists of a surgical thread and 6 small copper tubes, which are in the shape of a long strip, and can be placed deep in the apex of the uterus with a placer. Its mechanism of action is the same as other copper-containing IUDs, causing foreign body reactions in the endometrium, which is not conducive to the implantation of fertilized eggs; at the same time, the copper ions released by it also interfere with the movement of sperm and play a role in killing sperm.
曼月乐环载有孕激素，放置后每天向卵巢局部恒定释放少量的孕酮，使宫颈、宫腔内环境及卵巢内膜都处于不相宜受孕的状况，从而得到可靠的避孕效果，同时因为卵巢内膜处于休眠状况，还起到了削减经血血量，缩短经期出血时间，缓解经痛的效用。Mirena is loaded with progesterone. After being placed, a small amount of progesterone is constantly released to the ovary every day, so that the cervix, uterine cavity and ovarian endometrium are all in a state that is not suitable for conception, so as to obtain a reliable contraceptive effect. At the same time, because The ovarian endometrium is in a dormant state, which also reduces the amount of menstrual blood, shortens the time of menstrual bleeding, and relieves menstrual pain.
除了放置在宫腔内的避孕装置，还有放置在阴道中的避孕装置。阴道避孕环通常是由医用硅橡胶管制成的圆形环，环内放入孕激素。放置后不断缓慢地释放环中的避孕药，然后由阴道粘膜吸收后而发挥避孕作用。In addition to contraceptive devices that are placed in the uterine cavity, there are also contraceptive devices that are placed in the vagina. A vaginal contraceptive ring is usually a circular ring made of medical-grade silicone rubber tubing that contains a progestogen. After being placed, the contraceptive pill in the ring is continuously and slowly released, and then absorbed by the vaginal mucosa to exert a contraceptive effect.
以上所述的几种避孕装置，吉妮环的优点是不易脱落，但是没有治疗痛经的作用，而且放置的时候不易操作，医务人员在不可视的情况下将其置入宫腔内，很难检测是否放置在了合适的位置。曼月乐环的优点是既可以避孕又可以治疗痛经，但是一般存在痛经问题的子宫都较大，而曼月乐环并不能固定在宫腔，所以导致曼月乐环容易脱落或下移。阴道避孕环的优点是使用方便，使用者自行放入阴道最深处即可，但其缺点是不持久，有脱落或漏放的可能性。Among the several contraceptive devices mentioned above, the advantage of the Genie ring is that it is not easy to fall off, but it has no effect on treating dysmenorrhea, and it is not easy to operate when placed. It is difficult for medical staff to insert it into the uterine cavity without seeing it. Check if it is in the right place. The advantage of the Mirena ring is that it can both prevent pregnancy and treat dysmenorrhea, but generally the uterus with dysmenorrhea problems is larger, and the Mirena ring cannot be fixed in the uterine cavity, so the Mirena ring is easy to fall off or move down. The advantage of the vaginal contraceptive ring is that it is easy to use, and the user can insert it into the deepest part of the vagina by himself, but its disadvantage is that it is not durable and may fall off or be missed.

下面将结合本实用新型实施例中的附图，对实施例进行清楚、完整地描述，显然所描述的实施例仅仅是本实用新型的一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域相关技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。The embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present utility model.
图1为本实用新型第一实施例的避孕装置的剖视图。如图1所示，避孕装置100的形状类似于钉，以下称之为避孕钉。避孕钉100主要由三部分构成：第一主体部分101、第二主体部分102以及固定部分103。以下详细介绍各部分。Fig. 1 is a cross-sectional view of a contraceptive device according to a first embodiment of the present invention. As shown in FIG. 1 , the contraceptive device 100 is similar in shape to a spike, and is referred to as a contraceptive spike hereinafter. The contraceptive nail 100 is mainly composed of three parts: a first body part 101 , a second body part 102 and a fixing part 103 . Each part is described in detail below.
第一主体部分101呈帽型结构，由铜构成，可以采用CU380，其中380代表铜的释放面积。通过铜帽直接释放铜离子，可达到高效的避孕效果。在The first body part 101 is a hat-shaped structure made of copper, and CU380 can be used, where 380 represents the release area of copper. Direct release of copper ions through the copper cap can achieve high-efficiency contraceptive effect. exist
第一主体部分101的内部形成凹陷部分104。第二主体部分102呈棒状，由硅胶材料构成。第二主体部分102嵌入凹陷部分104从而与第一主体部分相卡合。这里，第二主体部分102嵌入凹陷部分104而卡合的形式有多种，也就是说，凹陷部分104的截面可以是多种形状，例如长方形、倒梯形等。第二主体部分102嵌入到凹陷部分104的部分的内径可以略大于凹陷部分104的内径，由于硅胶构成的第二主体部分略软，因此内径略大于凹陷部分104的内径的话，嵌入凹陷部分104后则硅胶棒膨胀而按压凹陷部分104的侧壁，从而使得卡合更牢固。The inside of the first body part 101 forms a recessed part 104 . The second body part 102 is rod-shaped and made of silicone material. The second body part 102 is inserted into the recessed part 104 to engage with the first body part. Here, there are various ways in which the second body part 102 is embedded into the recessed part 104 to engage. That is to say, the cross section of the recessed part 104 can be in various shapes, such as a rectangle, an inverted trapezoid, and the like. The inner diameter of the part where the second body part 102 is embedded into the concave part 104 can be slightly larger than the inner diameter of the concave part 104. Since the second body part made of silica gel is slightly soft, if the inner diameter is slightly larger than the inner diameter of the concave part 104, after being embedded in the concave part 104 Then the silicone rod expands and presses the sidewall of the recessed part 104, so that the engagement is stronger.
第二主体部分102内含长效缓释孕激素，放置后每天向局部恒定释放少量的孕酮，使宫颈、宫腔内环境及卵巢内膜都处于不相宜受孕的状况，从而得到可靠的避孕效果，同时因为卵巢内膜处于休眠状况，还起到了削减经血血量，缩短经期出血时间，缓解经痛的效用。The second main part 102 contains a long-acting slow-release progesterone, and after being placed, a small amount of progesterone is released locally every day, so that the cervix, uterine cavity and endometrium of the ovary are all in a state that is not suitable for conception, so as to obtain reliable contraception As a result, at the same time, because the ovarian endometrium is in a dormant state, it also reduces the amount of menstrual blood, shortens the time of menstrual bleeding, and relieves menstrual pain.
固定部分103由形成于第二主体部分102末端的硅胶软丝构成，硅胶软丝上形成倒刺结构。本实用新型的避孕钉放置于宫颈上，这一点与以往的避孕装置不同，以往的避孕装置多放置于宫腔内。固定部分103的倒刺结构嵌入宫颈上，使得避孕钉能够固定于宫颈，不易脱落。宫颈一般长度为2.5cm～3cm，为了将避孕钉更好的放置于宫颈上，需控制其尺寸。第一主体部分的高度可以为0.5cm，第二主体部分的高度可以为1cm，固定部分的长度可以为0.5cm。The fixing part 103 is composed of a silicone soft wire formed at the end of the second main body part 102, and a barb structure is formed on the silicone soft wire. The contraceptive nail of the utility model is placed on the cervix, which is different from the previous contraceptive devices, which were mostly placed in the uterine cavity. The barbed structure of the fixing part 103 is embedded in the cervix, so that the contraceptive nail can be fixed on the cervix and is not easy to fall off. The general length of the cervix is 2.5cm to 3cm. In order to better place the contraceptive nail on the cervix, its size needs to be controlled. The height of the first body part may be 0.5 cm, the height of the second body part may be 1 cm, and the length of the fixing part may be 0.5 cm.
在放置本实用新型的避孕钉时，使用配套的一次性放置器，将避孕钉置入宫颈，将避孕钉的倒刺结构辅助扎入宫颈组织中，就像耳钉一样。与以往的避孕装置相比较，放置避孕钉的过程简单，易操作，而且倒刺结构嵌入宫颈组织后不易脱落。此外，本实用新型的避孕钉既有避孕的效果，又有治疗痛经的功效。因此，可以说是综合了以往的避孕装置的优点。When placing the contraceptive nail of the present utility model, a matching disposable placer is used to place the contraceptive nail into the cervix, and the barbed structure of the contraceptive nail is assisted into the cervical tissue, just like earrings. Compared with the previous contraceptive device, the process of placing the contraceptive nail is simple and easy to operate, and the barbed structure is not easy to fall off after being embedded in the cervical tissue. In addition, the contraceptive nail of the utility model not only has the effect of contraception, but also has the effect of treating dysmenorrhea. Therefore, it can be said that the advantages of conventional contraceptive devices are integrated.
