Product introduction:
Safree is a sanitary napkin designed for visually impaired women. It changes the traditional style of existing sanitary napkins, making it more convenient for visually impaired women to purchase, replace and discard sanitary napkins during menstrual management, and can provide visually impaired women with good menstrual experience. It sets a reminder mechanism in the sanitary napkin to avoid the leakage of menstrual blood and protect the dignity of visually impaired women. Change the traditional product form, reduce the steps of replacing sanitary napkins, and make the menstrual management of visually impaired women more convenient.

According to the World Health Organization, 7 million people are blind every year, and there are nearly 45 million blind people in the world, including about 25 million visually impaired women, who experience 400 periods in their lives. More than 90% of women suffer from different degrees of gynecological diseases. Among visually impaired women, 96% of women use sanitary napkins during menstruation, and 53% of women change sanitary napkins less than 4 times a day. If they do not change sanitary napkins for a long time, it will lead to gynecological diseases.

Solution:
1. Cool reminder replacement
The material of the reminder mechanism is composed of PVA water-soluble film wrapped in menthol. When the menstrual blood diffuses to the reminder line, the water-soluble film dissolves and menthol releases coolness. Remind blind women to replace sanitary napkins in time to avoid menstrual blood leakage.
2. Reduce the steps of changing napkins
The product is designed in the form of belt + sanitary napkin sticker. Users do not need to wear underwear during menstruation. When replacing sanitary napkins, they only need to stick sanitary napkins on the belt without dragging underwear for pasting, thus reducing the replacement steps.
