摘要： A tampon pledget has an absorbent mass of material and a withdrawal string located at one end thereof. During use, the tampon pledget expands to take on a geometric configuration that approximates the shape of the vagina into which the tampon pledget is inserted. An anthroprometrically expandable tampon pledget has an absorbent mass of material that is defined by a first end having a first density, a second end having a second density, and a portion intermediate the first and second ends. The material expands at different rates upon being contacted by body fluids, thereby allowing the tampon pledget to conform to the shape of a vagina. A method of making an expandable tampon pledget includes the steps of providing an absorbent material, attaching a string thereto, and compressing the material into a cylindrical shape such that a density gradient is realized over a length of the compressed material.

摘要： A method for the study and evaluation of the performance of medical devices in vivo is disclosed. The medical devices are preferably tampons that are observed and evaluated in the vaginal cavities of women during their menstrual cycles in order to obtain data relative to tampon performance for the improvement of tampon technology. The method preferably uses magnetic resonance imaging (MRI), although other types of imaging techniques may be used. The present invention also resides in a method of MRI analysis in which a three-dimensional surface model image of a medical device such as a tampon or similar feminine hygiene product in vivo is created from two or more two-dimensional cross section images and combined with a second surface model image to produce a single image.
摘要翻译：公开了一种研究和评价体内医疗器械性能的方法。医疗装置优选是在其月经周期期间在妇女的阴道腔中观察和评估的棉塞，以获得相对于棉塞性能的数据，用于改进卫生棉条技术。该方法优选使用磁共振成像（MRI），尽管可以使用其他类型的成像技术。本发明还涉及一种MRI分析方法，其中由两个或更多个二维截面图像产生体内诸如棉塞或类似女性卫生产品的医疗装置的三维表面模型图像，并与第二表面模型图像以产生单个图像。

摘要： A tampon pledget includes crosslinked cellulose fibers having microstructures treated to provide improved absorbency and higher wet strength. The fibers are treated with a crosslinking agent to provide at least one of a molecular weight between crosslinks of from about 10 to 200 and a degree of crystallinity of from about 25% to 75%. The crosslinking agent includes citric acid in 1% by weight. The crosslinking agent may further include sodium hypophosphite in 1% by weight. In another embodiment, the crosslinking agent may be a difunctional agent including a glyoxal or a glyoxal-derived resin. In still another embodiment, the crosslinking agent is a multifunctional agent including a cyclic urea, glyoxal, polyol condensate. The crosslinking agent is added in an amount from about 0.001% to 20% by weight based on a total weight of cellulose fibers to be treated and, preferably, in an amount of about 5% by weight.
