Abstract

气球避孕法就是通过放置器具放置未能充气的气球到宫颈口,放置后进行充气,阻断阴道和子宫的通道完成避孕的目的,是器具避孕的一种,这种方法与避孕套比较起来有优点,但是,相对而言操作稍显麻烦。

Description

气球避孕法
技术领域
本发明属于避孕器材和避孕技术。
背景技术
避孕(Contraception)是应用科学手段使妇女暂时不受孕,主要控制生殖过程中的三个环节:1.抑制精子与卵子产生;2.阻止精子与卵子结合;3.使子宫环境不利于精子获能、生存,或者不适宜受精卵着床和发育,目前的避孕方法多种多样,但总体上为四大类,即药物,手术,器具和利用生理规律,药物避孕例如长效避孕药,杀精剂等,手术避孕例如输精管结扎术,输卵管结扎术,器具避孕例如避孕套,利用生理规律避孕例如安全期避孕法,体外射精,有时候是几种方法同时使用,例如通过手术放入节育环,不过,很难有避孕方法有百分百的优点,能够适用所有年龄阶段和所有类型的妇女有通过检索百度百科,我国育龄妇女广泛适用的上环,自1968年Scott报导危重疾病和死亡与宫内节育器有关以来,近十年期间,大量的研究报导了这种避孕方法对使用者的危险性,其中盆腔炎症(简称PID),子宫穿孔,异位妊娠(俗称宫外孕),自然流产或感染性流产是特别重要的合并症。
发明内容
有益效果:本发明在于利用简单的人工操作将避孕器具置于女性体内,阻止精子进入子宫从而达到避孕目的。
技术要点:气球两头大,中间小,以防脱落,后端有充气口,充气口内侧有挡舌,挡舌的作用是充气后挡住充气口,防止漏气,放置前,没有充气,利用经过消毒后的放置器具放置气球到宫颈口,放置后进行充气,这样,阻断子宫和阴道的通道达到避孕目的,取出时只需要通过充气口放气,拉出来即可。
具体实施方式:实施例1:由于宫颈口本身对异物是很排斥的,所以,气球并不需要多大,充气后的气球其外径最多达到成年人的小拇指直径大小就完全符合要求了,可以利用宫颈口自身的收缩作用牢牢的锁住气球,将阴道和子宫通道阻断,这样的气球没有充气时体积也很小,在气球中防止少量水,将放置器具置于阴道中,中间部位是空的,对准宫颈口,将气球放入,气球在水的重力作用下,缓慢进入宫颈口,待完全进入后,就可以充气使用了,滑入式实施方法的优点是利用水的重力作用,对女性无痛苦,这种放置器具由于气球是滑入式进入的,没有人工干预,不过,宫颈一旦触碰到异物,就会锁闭,这样就会放置失败,需要女性的宫颈口比较大,而且躺姿正确,在放置的过程中不触碰到宫颈,需要比较高的放置技巧。
实施例2:实施例2是人工主动干预放置的,和实施例1在气球方面是没有区别的,不同的是,实施例2的放置器具是前端直接伸入宫颈,放置器具前端是探针,其最前端是球状或半球状,椭球形等圆滑状,总之不能是尖端状,以防伤害女性身体和破坏气球,使用时,探针涂抹润滑剂,然后将气球通过充气口套在探针上,放入宫颈,放置好后,将放置器具取出,充气就可以使用了,探针部位最好有一定的弹性和刚性,能够产生一定程度的弯折,以适应不同的人群。
技术存在的问题:宫颈口如果长期存在气球,可能造成子宫黏液变稠,炎症等,也就是存在节育环同样的问题,但是,气球是放置在宫颈口的,女性不适时可以随时取出,其症状也应该不及节育环那么严重,而且女性可以在不适合性生活的时段,例如月经期取出,还有一个问题就是气球有可能漏气,从而达不到避孕目的,因此,需要在性生活前利用阴道扩张器等观察有无漏气,或者需要隔一定的时段更换气球,以防气球遭到腐蚀破损漏气,再就是气球压力的大小,压力太小,可能难以完全起到阻隔作用,但压力太大,爆裂时可能伤及女性身体,需要专门的打气工具,精确的控制气球压力。
