The diameter of tampons is usually smaller than fingers, with common specifications ranging from 5 to 15 mm in diameter. The specific size varies depending on the model and the amount of absorption.
1. Standard size comparison:
The diameter of ordinary tampons is about 8 to 12 mm, which is equivalent to the thickness of a pencil, while the diameter of an adult finger is generally 15 to 20 mm. The design of tampons needs to take into account the anatomical structure of the vagina, and the diameter is significantly smaller than the finger to avoid discomfort. Different flow models such as ordinary, large, and super large will have a diameter difference of 1 to 3 mm.
2. Material affects touch:
Tampons are made of high-density compressed cotton fiber material, which will swell but remain soft when encountering body fluids. Unlike the bone and muscle structure of fingers, the surface of tampons is smooth and elastic, and will not produce a finger-like sense of pressure in actual use. Some brands will add silicone coating to further reduce friction.
3. Advantages of catheter design:
The outer tube diameter of modern catheter tampons is about 5 to 8 mm, which is thinner than fingers when inserted. The inner core tampon can smoothly enter the deep vagina under the protection of the catheter. The tampon will not be fully unfolded until the catheter is removed. This design significantly reduces the foreign body sensation of first-time users.
4. Consideration of individual differences:
The vaginal sphincter has good ductility and can accommodate 2-3 fingers with a width of about 30 mm under normal conditions. The diameter of the tampon is far below this threshold, but it is recommended to use it when the cervix is at a low position during menstruation. A few people with narrow vaginas can choose a mini model with a diameter of 5-7 mm.
5. Key points for correct use:
Choose the smallest diameter tampon suitable for flow, and keep a 45-degree angle towards the sacrum when inserting. After fully pushed in, the catheter head should be 1-2 cm inside the vaginal opening, and the position of the tampon should not be felt at this time. If discomfort persists, it is necessary to check the placement depth or model selection problem.
