Abstract

一种放置于人体子宫内的活性节育环,由柔性环形胎芯、柔性芯杆和封闭弹簧环构成,在柔性芯杆上缠绕有200mm2的子铜丝T2,其优点在于妇女带环妊娠率有显著下降,同时还具有放取方便,副作用小,脱落率低,便于透视等优点。

Description

本实用新型涉及人体子宫内避孕器具中的一种节育环。
子宫内节育器作为放入人体中的异物,通过局部效应发挥其避孕作用。目前最常用的是不锈钢丝卷成的弹簧软环。这种环以环形塑料胎芯为支架,胎芯上缠绕有不锈钢丝。这种金属塑料环与没有塑料胎芯的不锈钢节育环相比,脱落率大大降低,移位的可能性也有所减少,从而降低了妊娠率,提高了继续存放率。但金属塑料环属于惰性节育器,年每百妇女的妊娠率为4.5%。T形节育器,属于活性节育器,但放置时需要扩张子宫;子宫出血量大;容易发生子宫穿孔的情况;节育器上系有尼龙尾丝,会给人体带来不适的感觉。
本实用新型的任务是提供一种改进型活性节育环,它不仅具有金属塑料环放取方便、付作用小、便于透视的优点,而且明显地降低了妊娠率。
本实用新型是这样实现的,在原有的金属塑料环基础上,在环形塑料胎芯沿直径方向联接一段柔性芯杆,柔性芯杆的末端悬空。柔性芯杆上密绕着金属丝,金属丝的表面积总和大于200mm2
下面结合附图对本实用新型做详细描述。
附图1金属塑料环示意图。附图2是本实用新型的一个实施例。柔性环形胎芯(1)与柔性芯杆(2)采用软质塑料一次注塑成型。在环形胎芯(1)上环绕有以不锈钢丝做的封闭弹簧环(3),在柔性芯杆(2)上密绕紫铜丝T2(4)。紫铜丝T2表面积总和为250mm2。封闭弹簧环(3)的直径为2.2mm。柔性芯杆(2)的长度为16mm。
本实用新型与已有技术相比,带环妊娠率有显著下降,在近一年的临床试用中,数百人中至今还未发现有带环妊娠病例发生。充分体现了放置活性节育环的优越性。同时它还具有放取方便,付作用小,脱落率低、便于透视等优点。

Claims (2)

1、一种放置于人体子宫内的节育环,它是由柔性环形胎芯(1)和封闭弹簧环(3)组成,其特征在于柔性形胎芯(1)沿直径方向联接一段与柔性环形胎芯(1)不相连的柔性芯杆(2),柔性芯杆(2)上密绕着金属丝(4)。
2、按权利要求1所说的节育环,其特征在于金属丝(4)为紫铜丝T2,缠绕在柔性芯杆(2)上的铜丝表面积大于200mm2
