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

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of medical device design for uterine disease treatment, in particular to a drug-carrying slow-release device for uterus and an implantation method. Background technique [0002] Uterine inflammation is a common gynecological disease, which brings great troubles to female patients. Current options for treating uterine inflammation include oral medication and vaginal packing. [0003] The advantage of oral medicine is that it is convenient to take, but the disadvantage is that some patients who need precise indications for administration are forced to circulate the medicine through the whole body because of oral administration without targeting, and the pertinence and therapeutic effect are greatly reduced. [0004] The advantage of vaginal packing is that it is convenient to use and relatively targeted. The disadvantage is that after packing, there is no support, which will lead to absorption or flow out of ...

[0006] Chinese Patent No. 200410050861.7 discloses a new type of pessary, which can realize the method of placing drugs in the vagina to treat cervicitis, but it cannot achieve long-term sustained release drug delivery

However, the existing problem is that this micropore drug delivery method is relatively limited, limited to drugs between 0.1nm and 10nm, and the diameter of the micropore is too small to easily block, which is not conducive to the m
