Abstract

本实用新型涉及一种妇女避孕器具,是一种宫内 节育器。由立轴、臂、铜丝等组成,臂固定在立轴上 部,向后弯曲形成以立轴为长轴的半封闭椭圆形,铜 丝缠绕在立轴上,其特点是置入取出方便,妊娠率、脱 落率低,适合于推广使用。

Description

本实用新型涉及一种避孕装置,特别是一种宫内节育器。
现在,妇女避孕器具装置有许多种,如我国普遍使用的金属环,及近来发展起来的“丫”型、“T”型等宫内节育器。但在使用过程中存在着置入、取出困难(需扩张宫颈)或存在着妊娠率、脱落率高等缺点,以致于影响其推广使用。
本实用新型的目的在于提供一种新型宫内节育器,集中了金属环、“T”型宫内节育器等的优点,克服使用后妊娠率、脱落率高及置入、取出不便等缺点。
本实用新型的构思为:利用人体子宫形状,将节育器的臂设计成以立轴为长轴向后弯曲的半封闭椭园形,并具有一定弹性。
附图为本实用新型结构图。
本实用新型由立轴(1)、臂(2)、凸块(3)、铜丝(4)、尾丝(5)等组成,其中臂(2)固定在立轴(1)的上部,向后弯曲形成以立轴(1)为长轴的半封闭椭园形,在臂(2)上均匀分布有10个凸块(3),立轴(1)的顶部为光滑的半园形,以防置入时划伤子宫内壁,另外还有铜丝(4)缠绕在立轴(1)上,铜丝的绕制,增大了铜的表面积,加强了铜释放的避孕层,延长了使用年限。为取出方便,立轴(1)后还有一尾丝(5)。
在实施例中,本实用新型用高分子塑料制造立轴及弯曲的臂,采用375MM2的裸铜丝缠绕立轴。
该实用新型的优点在于集中了金属环置入后出血少,适应子宫形状的特点,又吸收了“T”型宫内节育器竖臂不易脱落及含有铜释放避孕层的特点,结构简单,置入、取出容易,便于推广。

Claims (3)

1、一种宫内节育器,由立轴(1)和臂(2)等组成,其特征在于所述的臂(2)在立轴(1)的上部,向后弯曲形成以立轴(1)为长轴的半封闭椭园形,立轴(1)的顶部为光滑的半园形。
2、根据权利要求1所述的宫内节育器,其特征在于所述臂(2)上均匀分布10个凸块(3)。
3、根据权利要求1和2所述的宫内节育器,其特征在于还有铜丝(4)缠绕在立轴(1)上。
