Tampons

Hi, this is about tampons it is for girls only so enjoy reading.A tampon is a mass of cotton or rayon; or a mixture of the two inserted into a body cavity or wound to absorb bodily fluid. The most common type in daily use (and the topic of the remainder of this article) is disposable and designed to be inserted into the vagina during menstruation to absorb the flow of blood. Several countries—including the United States, under the banner of the Food and Drug Administration (FDA)—regulate tampons as medical devices.

History
The ancient Egyptians invented the first disposable tampons made from softened papyrus.[citation needed] The ancient Greeks created tampons made from lint wrapped around a small piece of wood, recorded in writing by Hippocrates in the fifth century B.C.[citation needed] Physicians in the medieval Islamic world also described the use of tampons, often for contraceptive purposes.[1] Other materials used for the first tampons have included: wool, paper, vegetable fibers, sponges, grass, and later cotton.
As a medical device, the tampon, (from the French for plug, or stopper[2]) has been around since the 19th century, when antiseptic cotton tampons treated with salicylates were used to stop the bleeding from bullet wounds,[3] and there have been reports of modern menstrual tampons being used for the same purpose by soldiers in the Iraq War.[4]
The applicator tampon with removal cord was invented in 1929 and submitted for patent[5] in 1931 by Dr. Earle Haas, who hailed from Denver, Colorado. Dr. Hass later sold the patent of the applicator tampon to Gertrude Tendrich, who founded the Tampax Company for the mass production of the lengthways expanding tampon.
It is documented that gynecologist Dr. Judith Esser-Mittag developed, during her studies on the female anatomy, the digital design of tampon. In the late 1940’s, Dr. Carl Hahn, together with Heinz Mittag, worked on the mass production of such a tampon. Dr. Hahn sold his Company which included the digital style tampon range to Johnson and Johnson in 1974. The first fully [edit] Design and packaging
Tampons come in various sizes, which are related to their absorbency ratings and packaging. The outward appearance of a tampon is similar for all brands, but their absorbency varies. The two main differences are in the way the tampon expands when in use; for example applicator tampons such as Tampax tampons and Natracare tampons will expand axially (increase in length), while OB, Natracare and Lil-lets digital tampons will expand radially (increase in diameter). All tampons have a cord for removal and some have an additional outer cover to aid insertion and withdrawal. Some women prefer to use a tampon which is contained within an applicator to further aid insertion. The majority of tampons sold are made of rayon, or a blend of rayon and cotton. Organic cotton tampons are made from only 100% cotton. Tampons are sold individually wrapped to keep them clean, and because the vagina is not a sterile body-cavity, and for the vast majority of women contains “good bacteria”, there is no need for any menstrual device to be sterilized.
Tampon applicators may be made of plastic or cardboard, and are similar in design to a syringe. The applicator consists of two tubes an ‘outer’ and ‘inner’. The ‘outer’ tube has a smooth surface to aid insertion and sometimes comes with a rounded end that is petalled.
The tampon itself sits inside the ‘outer’ tube, near the open end. The ‘inner’ tube is encased inside the ‘outer’ tube and held in place by a locking mechanism. The ‘outer’ tube is inserted into the vagina, then the ‘inner’ tube is pushed into the outer tube (typically using a finger) pushing the tampon through and into the vagina.
Digital or non-applicator tampons are tampons sold without applicators; these are simply unwrapped and pushed into the vagina with the fingers.certified organic, 100% cotton tampons were developed by Natracare in the early 1990s
