The present invention introduces a tampon with an integrated device designed for improved insertion, and removal, and leak prevention. The device comprises a flexible, nonpermeable wall, hollow to enable finger-assisted insertion and featuring a removal aid element attached to the bottom end of the wall for easy, hygienic extraction. Additionally, the wall is equipped with ridges that conform to the vaginal wall, enhancing the seal to prevent menstrual fluid leakage and block the absorption of external fluids. In other embodiments, a smoothed wall is offered. This invention eliminates the need for separate applicators, allows the device to compact for discrete portability, and significantly enhances user comfort and effectiveness in fluid management.

A menstrual cup is disclosed, comprising a flexible, biocompatible collector configured for insertion into the vaginal canal and enabling hands-free emptying of menstrual fluid without removal. The collector body defines a fluid-retention chamber and includes one or more pressure-responsive valves and an outlet. The valves open in response to compression from voluntary abdominal or pelvic floor muscle contractions, allowing fluid evacuation while the device remains in situ. Upon release of pressure, the valves close to maintain a leak-proof seal. The valves also provide suction relief to equalize internal and external pressure during insertion or removal. Transverse reinforcement bands integrated into the collector body enhance pressure transfer and promote valve actuation. Unlike traditional menstrual cups that require removal for emptying, the present invention allows extended wear and periodic, hands-free drainage. The device may optionally incorporate biosensors and an applicator system for accurate placement of the cup into the vaginal canal.
