Description

1 TARIFF LACTATION SUPPRESSIVE BREAST PADS Technical Field to Which the Invention Relates 5 The invention consists of three layers: an outer layer, a cooling middle layer, and a phytotherapeutic inner layer. It is a multi-layered breast pad that suppresses lactation. It is used by breastfeeding women in various ways. in cases where it is necessary to reduce the amount of milk due to certain reasons The breast pad, which is the subject of the invention developed for use, contains mint extract in its inner layer. It is located. The controlled release of the mint extract in the invention and this active ingredient 10 By combining the cooling properties of the middle layer with the material, the milk ducts Milk production is reduced by narrowing the milk duct and suppressing β-casein synthesis. State of the Art 15 Breast pads used by breastfeeding women are generally disposable absorbent. sanitary pads, washable cloth pads, hydrogel pads, silicone pads, and plant-based pads is classified as [1]. Disposable absorbent breast pads are typically cellulose-based or made of superabsorbent polymers. Thanks to its structure containing 20, it absorbs milk leakage, which is common during breastfeeding. to prevent clothes from getting wet and to prevent moisture buildup around the nipple. They are used to reduce skin irritation [1]. However, these breast pads can cause milk irritation. They have no direct effect on milk production or the milk let-down reflex. Also, due to limited air permeability during prolonged use, the nipple... They cause moisture accumulation, maceration, and irritative dermatitis in the surrounding area. 25 Disposable breast pads containing perfume or synthetic absorbent polymers The use of these pads carries a risk of contact dermatitis and allergic reactions. Additionally, these pads... If they are not changed frequently, they create a breeding ground for bacteria and yeast. Washable fabric breast pads can be made from natural materials such as cotton, bamboo, or microfiber. Produced from semi-synthetic fibers, it similarly controls milk leakage. 30 They target and support the skin barrier thanks to their breathable structure. When fabric breast pads are properly maintained, they can prevent milk or breastfeeding from entering the body. It is reported that there are no negative effects [2]. However, when adequate hygiene is not provided 2 High risk of microorganism accumulation, need for washing and drying. There are disadvantages such as reduced practicality due to the fabric chest. Pads have lower absorbency compared to disposable pads, which is why they contain milk. This results in the fabric not being able to completely prevent clothing from getting wet in the event of a leak. Hydrogel breast pads are especially effective for cracked nipples, pain, and sensitivity. 5 These products, used to provide a moist healing environment with a high water content, are for the epithelium. It supports repair, reduces pain, and makes it easier to continue breastfeeding. [3]. Hydrogel breast pads do not have a direct effect on milk volume. Prolonged and continuous use of these pads creates an excessively moist environment. Excessive moisture around the breasts weakens the skin barrier, and this is especially true for women under 10. This leads to an increased risk of fungal infections, particularly Candida species. It opens. Silicone breast pads provide mechanical protection for the nipple, reduce friction, and in some cases for cosmetic purposes, to provide a neat appearance under clothing They are used [1]. Silicone breast pads alone do not have absorbent properties 15 And when they apply strong pressure, they cause sweating and irritation. Breast pads containing herbal or essential oils are commonly made from sage, lavender, chamomile, and aloe. Their compositions, containing vera or various plant oils and extracts, have a cooling effect on the nipple. to provide effect, reduce pain and tenderness, and soothe inflammation. is being developed [4]. In addition, the oil phase contained in these pads provides long-term contact 20 In this way, it forms an occlusive layer around the nipple, causing excessive moisture and affecting the skin. This can weaken the immune system and make people more susceptible to infections. An example of a technique using plant-based oils in breast pads is Aloe. Vera extract is infused into the inner surface of a cotton pad. This layer, which comes into contact with the skin... Aloe vera extract can help with breastfeeding-related skin irritation or sores on the nipple. 25 They are used to soothe problems. These breast pads also help with milk production. It absorbs leakage, ensuring the nipple always stays dry. Thanks to aloe vera's soothing, antiseptic, antibacterial, and skin-renewing properties It provides care for the nipple. However, breast pads containing aloe vera extract, It does not affect the amount of milk production [5]. 30 Another application of breast pads is therapy with a hot-cold effect. Unlike classic absorbent pads, these pads focus on physiological absorption rather than simply absorbing milk leakage. 3 These products aim to provide relief. These pads are usually gel-filled and reusable. It is suitable for use and, when applied as a hot treatment, can help unclog blocked milk ducts. to open, stimulate the milk flow reflex and the pre-breastfeeding breast tissue It helps to soften the skin, and when used as a cold application, it aids in childbirth. Breast fullness, swelling, pain, and mastitis developing after or between breastfeeding sessions. 5 It aims to alleviate similar inflammatory conditions [6]. Thermal Even though these applications help reduce the milk let-down reflex with frequent use, milk It does not have a direct, lasting effect on production. Therefore, thermal-based Breast pads are merely a supportive device; they cannot increase or decrease milk production. It offers alternatives. 10 Oils used to suppress milk production and the methods used in their application. or medical products, in terms of their mechanisms of action, mostly involve the release of oxytocin reducing blood flow to the breast tissue or indirectly reducing the prolactin response. It is based on the principle of suppression. In this context, peppermint oil in particular. (menthol) and sage (Salvia officinalis) oil have been reported in the literature to have lactation-suppressing effects at least 15%. These oils are among the frequently reported vegetable oils and are used for topical applications. (oils applied to the breasts, menthol creams) or systemic use (herbal tea, It can be used via capsules. Topical menthol applications are local. By causing vasoconstriction and a cooling effect, it stimulates the oxytocin-mediated milk release reflex. It weakens the body, while sage has phytoestrogenic components and prolactin-suppressing effects. 20 It is reported that it reduces milk production due to [7]. In clinical practice, such fats, especially during weaning, in cases of hyperlactation, or in cases of medical reasons related to breastfeeding In cases where discontinuation is necessary for certain reasons, menthol can be used as a supportive method. It is used in the form of breast balms or topical products containing sage, however Uncontrolled or prolonged use of these products during active breastfeeding poses a risk of 25%. It is emphasized that this can lead to an undesirable decrease in milk production. Therefore, although lactation suppressants containing vegetable oil are called "natural"... Due to its pharmacological effects, the dose and duration of use must be carefully considered by the user. It needs to be adjusted accordingly. Possible side effects of teas taken orally. The effects or absorption of the oil to be applied to the skin should be carefully monitored, and the oil should be thoroughly removed from the area. 30 Disadvantages such as the need for cleaning make things even more difficult for breastfeeding women. This will cause a change that reduces the amount of milk produced in breastfeeding women. A cream containing mint extract is known in another application of the existing technique. 4 A cotton-lined container is used to cover the cream after application to the skin. A breast pad is also provided in addition to the cream. This cream contains... Thanks to the extracts of plants such as mint, lemon and cabbage found in it, it helps breastfeeding women. It helps to suppress lactation [8]. However, the active ingredient in this cream concentration of substances and auxiliary substances used alongside the active ingredients 5 Although the quantities of the substances (preservatives, perfumes, stabilizers) are not known, this side effect... High concentrations of these substances can cause skin irritation, burning sensation, or contact. It increases the risk of dermatitis. In addition, with each use, the cream affects the user. It must be applied by hand and thoroughly cleaned before breastfeeding. Cream The application creates a layer on the skin, preventing excessive moisture around the nipple and 10 It also creates a breeding ground for bacterial or fungal infections. Current techniques involve products developed for the purpose of suppressing milk production in breastfeeding women. It falls short in this respect. These shortcomings, in general terms, are due to the current technology. This is due to the method of administration. Oral administration reduces milk production. The side effects of substances are not fully known by users, therefore 15 Inability to adjust the dose and duration of use is an example of inadequacy in terms of method of use. This constitutes a problem. However, the possible effects of the excipients in creams produced using current technology... negative effects and the effects of these creams both during and after application subsequently, there are additional challenges in terms of practicality and ease of use for the user. Creating it is another disadvantage of the current technique. In addition, the 20 in the current technique Breast pads are for moisturizing and cleaning purposes only, not to suppress milk production. The fact that it has been manufactured and thermal application alone cannot provide a permanent solution. This is among the shortcomings of the current technique. Milk production in breastfeeding women. To address these shortcomings in breast pads, new Further developments are needed. 25 Brief Description and Objectives of the Invention The invention consists of three layers: an outer layer, a cooling middle layer, and a phytotherapeutic inner layer. It is a multi-layered breast pad that suppresses lactation. It is used by breastfeeding women in various ways. in cases where it is necessary to reduce the amount of milk due to certain reasons This breast pad, developed for use with peppermint extract, contains 30 mint extract in its inner layer. It is located there. The invention contains mint extract and this active ingredient is in the middle layer. Thanks to its cooling properties, it reduces the narrowing of milk ducts and inhibits β-casein production. Milk production is reduced by suppressing its synthesis.
