Description

[Detailed description of the invention] Absorbent pad and its manufacturing method The present invention relates to menstrual tangents, surgical and wound dressings and filling materials, and surgical sponges. , regarding sanitary protection absorbent materials and diapers (hereinafter collectively referred to as absorbent bands). , more specifically, toxic shock syndrome toxin-1 and other toxins during use. A pad that is effective in substantially inhibiting the increase in the production of staphylococcal products, The present invention relates to a method for manufacturing a pad.

solid water-insoluble water-absorbing material in a desired form for application or insertion into a wound or body cavity; Absorbent pads formed into a shape and adapted for the absorption and retention of body fluids have been used for many years. has been used. In the production of such absorbent pads, cotton fibers and semi-synthetic Fibers such as acetate rayon, viscose rayon, polyacrylate rayon cellulose derivatives, polyurethanes, polyesters and other fibers, including various non-fibrous water-absorbing materials, particularly cellulose such as carboxymethyl cellulose. conductors, polymers such as water-swellable cross-linked polymers that can form hydrogels; Synthetic polymers, polyurethane sponges and others have been widely used. Ka-ru Suction The absorbent pad provides high volume absorption and retention properties and therefore during use of the absorbent pad Although providing a long period of protection, such an extended period of use is particularly important for menstrual tanning. Possible bacterial growth and toxin production near the absorbent pad in the case of The period during which this can occur has been increased. Toxic shock syndrome is caused by poison, a staphylococcus-produced toxin. It is a serious disease that has been found to be related to sexual shock syndrome toxin-1. regarding the use of certain brands of tampons and the use of certain nasal and other surgical filling materials. It's connected.

Therefore, in the present invention, a certain low concentration is lower than that normally present in body fluids such as blood. Concentrations of magnesium ions inhibit toxic shock syndrome toxin-1 and other staphylococcal organisms. critical for optimal production of compounds, some of which may be toxic. It was found that various absorbent pad materials absorb or absorb magnesium ions. was also found to have the ability to bind.

The present invention provides water-absorbing materials and $-shock syndrome toxins during use of the absorbent pad. A non-toxic compound that is effective in substantially inhibiting the production of Staphylococcus-1 and other staphylococcal products. The present invention provides an absorbent pad, particularly a menstrual tampon, comprising a divalent-ionic salt. Ma Additionally, the present invention includes forming the pad from a material of water-absorbing, water-insoluble solid material. In the manufacturing method of absorbent pads, the material is Substantially inhibits the production of toxic shock syndrome toxin-1 or other staphylococcal products Preparation of an absorption band characterized by the inclusion of a non-toxic divalent cation salt effective in It provides a manufacturing method. Further, the present invention provides a water-absorbing solid material with a magnet of the material. Contains sufficient non-toxic divalent cations to satisfy nesium absorption or binding capacity. and forming the material into a pad. and provide a method for producing magnesium adsorbents, and provide a method for producing magnesium adsorbents that are satisfied with non-toxic divalent cations. The present invention provides absorbent pads, particularly menstrual tampons, that have absorbent or binding capabilities.

the desired amount of divalent to saturate the magnesium absorption or binding capacity of the absorbent pad material. Any non-toxic material, provided that it is sufficiently water soluble to provide the cation. salts can be used. This absorption or binding capacity depends on the specific properties present in the pad. varies widely depending on the properties of the material and the manufacturing operations carried out in each case. example For example, in the case of keracrylate rayon fiber, t000 microI per gram of fiber. of magnesium acetate or even less is sufficient. divalent cation All non-toxic salts of ions compete with magnesium salts naturally present in body fluids. thus satisfying the absorption or binding capacity of the pad material for magnesium ions. Because of the additive effects, non-toxic salts can be used in the absorbent pads of the present invention. Good results are obtained with magnesium salts. Generally, between uses of absorbent pads to inhibit the production of Portobacterium syndrome toxin-1 or other toxic staphylococcal products. The salts are effective at suppressing pads to levels normally present in the absence of pads. It is sufficient to satisfy the magnesium absorption or binding capacity of the compound. suitable Salts include preferred cations such as magnesium, calcium, barium or or swantium salts or other suitable substances such as zinc, manganese, copper/iron, nickel, etc. Examples include salts of valent cations. The anionic part of salt is not strict but has a wide range. may vary over a period of time. This is because the water solubility is extremely low for the purpose of the present invention. Because sex is enough. Suitable salts include chloride, sulfate, nitrate, acetic acid. salt, palmitate, stearate, mandelate, Jg urate, etc. However, their magnesium salts are preferred.

Particularly preferred are magnesium stearate and magnesium acetate.

Salt is a completed band? in tampons by immersion in an aqueous solution or dispersion of salt. However, one or more of the constituent materials may be incorporated into the pad. treatment with the desired salt at some point in the manufacturing operation prior to or during incorporation of the material. is usually convenient and beneficial. For example, in the case of synthetic fiber materials, add appropriate salt. Contains an aqueous solution, in which the fibers can be passed through the bath, or where the salt solution is supplied. The fibers can be passed through a pair of squeeze rolls. Synthesis of magnesium stearate It is a preferred salt for application to fibers. This is because it supports the processing of fibers. This is because it makes it easier. Also, if it rests on a part of the pad/(on other parts of the pad) It is advantageous to distribute or diffuse it under the conditions of use. However, all of the pads The magnesium absorption or binding capacity of all W additives was determined initially before use of the pad. It is preferable to be satisfied.

Excessive pricking in excess of the amount necessary to saturate the magnesium absorption or binding capacity of the absorbing material salts are not harmful and therefore salts used to inhibit toxin production are There is no critical upper limit.

Although not intended to limit the invention to any particular theory or mode of operation, One or more of the water-absorbing solid materials normally present in pads such as pads are Toxic shock syndrome toxin-1 and other at a critical low level, where the production of toxic staphylococcal products is greatly enhanced. have sufficient magnesium ion absorption capacity or specific binding capacity to reduce It is also believed that the present invention works by removing this ability. .
