Medicine-taking slow release device for uterus, and implantation method

Abstract

本发明公开了一种用于子宫的带药缓释装置和植入方法,所述装置包括支架、网袋和凝胶体;所述支架整体呈套筒状,其四周侧壁形成有通孔;所述凝胶体由凝胶材料和药物组成;所述网袋的侧面形成微孔,所述网袋的内部形成容置腔;在使用状态下,网袋处于支架的内部,凝胶材料膨胀撑开网袋,药物透过微孔和所述通孔对外释放。所述植入方法为先将所述支架送入子宫内,再将所述网袋送入支架内,最后将所述凝胶体注入网袋内部。本发明通过支架的“自适应能力”形成有利可靠的外支撑,凝胶材料吸水膨胀的“顺应性”特点对网袋形成适度的内支撑,两者共同作用能够在子宫内部形成可靠、适宜的内部支撑,实现长期、可靠的进行子宫内部的缓释给药。
The invention discloses a medicine-taking slow release device for uterus, and an implantation method. The device comprises a support, a net bag, and gel. The support is integrally shaped like a sleeve, and the peripheral side wall is provided with through holes. The gel is made of gel materials and drugs. A side surface of the net bag is provided with micropores, and the interior of the net bag forms an accommodation cavity. In use, the net bag is located in the support, and the gel materials are expanded to enable the net bag to be opened. The drugs are released outwards through the micropores and the through holes. The implantation method comprises the steps: firstly enabling the support to be put into the uterus, secondly putting the net bag into the support, and finally enabling the gel to be injected into the net bag. Through the adaptive capability of the support, a reliable external support is formed. The adaptability characteristic that the gel materials absorb water to expand enables the gel materials form moderate internal support for the net bag. Through the interaction, the reliable and proper internal support can be formed in the uterus, thereby achieving the slow release application of drugs in the uterus reliably for a long time.
