Description

Fitting seat for breastfeeding aid

Technical Field

The utility model relates to the technical field of infant products, in particular to a fitting seat for a breastfeeding aid.

Background Art

Lactation refers to the biological phenomenon that animals feed their young with milk secreted from their mammary glands after giving birth. The milk is rich in nutrients and contains some special antibodies that resist diseases, which is extremely beneficial to the growth and development of young. Lactation promotes animals to protect and reproduce their offspring most effectively, and is one of the evolutionary characteristics of higher animals.

The World Health Organization believes that breastfeeding is the most beneficial food for infant growth, and its health benefits can continue into adulthood. More and more studies have shown that breast milk is the safest, most natural, and most nutritious natural food for infant growth. Breast milk can provide infants with sufficient nutrition for development, and can also provide antibodies to protect infants from viruses and bacteria; through close contact such as breastfeeding, it can also stimulate the brain and mental development of infants.

When a new mother feeds her baby for the first time, it is very easy for her to have nipple pain and cracks. Some mothers also have problems with inverted nipples and cannot breastfeed smoothly. The advent of nipple shields solves the above problems. However, most of the existing products on the market are single-layer structures, that is, they only have a human-like shield and a front receiving cavity structure. Due to differences in the human body, such a structural design generally has poor fit. Since there is only one receiving cavity, once the baby does not suck in time, milk will be stored in the receiving cavity, which will lead to milk seepage between the skin and the shield, making the fit even worse. There are also double-layer nipple shields on the market, the upper layer of which is a bottle and nipple structure, and the lower layer uses a hard base. The hard base not only affects the mother's touch, but also does not fit the skin. It usually needs to be held by hand when in use, and the overly long double-layer structure causes the distance between the nipple and the nipple to be too large, making it difficult to suck.

The patent document with authorization announcement number "CN213191282U" discloses a nipple shield, which includes a nipple shield body, a fitting and fixing layer and a negative pressure positioning layer. The nipple shield body is composed of a fitting and fixing layer and a negative pressure positioning layer. A negative pressure positioning layer is arranged on the outside of the fitting and fixing layer. The patent document adds a fixing layer and removes a milk storage bin, which not only solves the problem that single-layer silicone shields on the market are easily displaced, loosened and fall off, but also solves the problems of air inhalation and choking during feeding. Since the patent document simply provides a negative pressure positioning layer, when the negative pressure positioning layer and the breast are in close contact due to negative pressure, it is easy for the nipple to fall off the breast due to air leakage. At the same time, since the milk storage bin is removed, when milk flows out, it will seep out from the contact point between the negative pressure positioning layer and the breast due to the lack of milk storage bin. When the milk seeps out, it is more likely to accelerate air leakage, resulting in falling due to lack of negative pressure. In addition, the entire nipple shield in the patent document is an integrated structure. When the baby is feeding, the nipple is sometimes bitten, so the nipple is the most easily damaged part. In the patent document, when the nipple is damaged by the baby's biting, it will more easily cause air leakage. At this time, the entire nipple shield needs to be discarded as a whole and a new one needs to be purchased, which increases the cost of use.

Therefore, the existing nipple shields for assisting mothers in breastfeeding have the problems of poor fit and easy leakage of milk.

Utility Model Content

In order to solve the above technical problems existing in the existing nipple protection shield for assisting mothers to breastfeed their children, the utility model provides a fitting seat for a breastfeeding aid which has good fitting properties and is not easy for milk to leak out.

Under the force of negative pressure formed in the negative pressure chamber by the second supporting part recovering its deformation, the fitting seat will be able to fit stably on the mother's breast to achieve smooth breastfeeding of the child. When it is necessary to remove the fitting seat from the mother's breast, it is only necessary to press the second supporting part again with hand to deform it and release the negative pressure inside the negative pressure chamber. When in use, the fitting is tight and firm, and it is not easy to leak. The negative pressure is reduced by reducing the air, and the problem of the fitting seat being detached from the mother's breast and falling off may be avoided. The fitting surface will not bulge after a long period of use. The arrangement of multiple negative pressure holes and negative pressure chambers in the utility model can also serve as a third line of protection for accommodating leaked milk. When a small amount of milk leaks out of the third accommodating chamber, the leaked milk may enter the negative pressure chamber from the negative pressure hole closest to the third accommodating chamber.

The shape of the fitting surface is an arc surface matching the breast skin. The negative pressure hole is a waist-shaped hole. The connection between the first support portion and the fitting surface is an arc transition connection. The sucking portion is an integrally formed structure. The fitting seat is an integrally formed structure. The sucking portion and the fitting seat are both made of food-grade latex and/or food-grade silicone.

In actual use, the utility model needs to be disinfected for the first time, and the breastfeeding part of the human body needs to be properly disinfected. The disinfection of the utility model can be high-temperature sterilization or other reasonable disinfection methods. After disinfection, the sucking part 100 is installed on the fitting seat 200 through the structural seal of the clamping protrusion and the clamping groove, and a few drops of breast milk are dripped into the first accommodating cavity 104, and then the breast is placed in the third accommodating cavity 204, and the nipple is placed in the first accommodating cavity. At the same time, the fitting surface 206 is fitted to the skin, and then the second support part 202 is gently pressed by hand to slightly discharge the air in the negative pressure 205, and then the fitting surface is fitted to the skin. At this point, the assembly and wearing process of the breastfeeding aid is completed, and then the breastfeeding aid can be gently supported by hand for breastfeeding. Compared with existing products, the first accommodating cavity 104 and the second accommodating cavity 105 that are in direct contact with the nipple are reduced in size, so that the baby can drink breast milk as soon as possible, and the risk of lotion penetrating into the fitting surface is greatly reduced; the utility model is designed to have a double-layer inner wall structure, namely, including a first support portion 201 and a second support portion 202, which further avoids the risk of lotion penetrating to the outside, and at the same time increases the fit between the product and the human body, further improving the use effect.

The sucking part 100 in the utility model is used for the child to suck, so that the child can drink the mother's milk; the fitting seat 200 is used to fit closely with the breast, and can be stably fitted on the mother's breast without any hand support during use, so that the child can drink milk independently; the sucking part and the fitting part are detachable, and when the sucking part is bitten by the child due to long-term use, only a new sucking part is needed, and the fitting seat does not need to be replaced. Compared with the need to re-purchase the nipple protection shield, the use cost is reduced; the utility model provides a double support structure of a first support part 201 and a second support part 202, wherein the first support part is located inside the second support part, It plays a good supporting role during use and has a leak-proof protection effect on the breast and the internal milk; the mounting hole 203 is used for the detachable mounting of the sucking part on the fitting seat; the third accommodating chamber 204 is used to accommodate part of the mother's breast. When the milk flows out, the third accommodating chamber is used to accommodate part of the milk that flows out, so there is no problem of the milk flowing out and wetting the clothes of the mother and the child, and there is no problem of leakage and decompression of the milk during the seepage process, so that the fitting seat falls off the mother's breast; the utility model provides a negative pressure chamber 205 between the first supporting part and the second supporting part, and provides a fitting surface 206 at the end of the first supporting part that contacts the mother's breast The end of the second supporting part in contact with the mother's breast is connected, and the negative pressure chamber is formed by connecting the first supporting part, the second supporting part and the fitting surface and then closing them. A plurality of negative pressure holes 207 are arranged on the fitting surface. Since the fitting seat is made of soft material, the second supporting part is deformed by initially pressing the second supporting part. The suction cup principle is adopted to make the fitting surface fit well with the mother's breast. Then, the pressure of the second supporting part by the human hand is released, and the second supporting part recovers its deformation to form a negative pressure force in the negative pressure chamber. The fitting seat equipped with the sucking part will be able to stably fit on the mother's breast to achieve smooth breastfeeding of the child. When the fitting seat needs to be removed from the mother's breast, it only needs to be removed with The second supporting part can be deformed by pressing the hand again to release the negative pressure inside the negative pressure chamber. When in use, the fit is good and firm, and it is not easy to reduce the negative pressure due to air leakage, or even the fitting seat will fall off the mother's breast. One fitting surface will not bulge after a long time of use. The arrangement of multiple negative pressure holes and negative pressure chambers in the utility model can also serve as a third protection for accommodating leaked milk. When a little milk leaks out of the third accommodating chamber, the leaked milk may enter the negative pressure chamber from the negative pressure hole closest to the third accommodating chamber. In short, the leaked milk will never leak out from the inside of the fitting seat, thereby ensuring the absolute anti-leakage property of the milk.

The sucking body 101 is installed in the installation hole 203, and serves as a support for the entire sucking part 100 and a connecting part with the fitting seat 200; the sucking head 102 is the sucking part of the child, which is the part where the child sucks milk, and is also the part that is easily damaged by the child's biting; the sucking hole 103 is the outflow hole for milk, and the child sucks the sucking head, and the milk will be sucked by the child from the sucking hole; the first accommodating cavity 104 is used to accommodate the mother's nipple, so that it is easier for the child to suck it. For mothers with smaller nipples or concave nipples, the mother's nipples are also very close to the first accommodating cavity, and at this time the first accommodating cavity The cavity will be filled with milk flowing from the mother's nipple. The child sucks the sucking head. Under the action of the child's sucking force, the child can eat the milk in the first accommodating cavity. At the same time, new milk will continue to flow out from the mother's nipple and enter the first accommodating cavity again to be eaten by the child; the second accommodating cavity 105 is used to accommodate the connection between the current breast and the nipple, and is also used to accommodate the milk flowing from the first accommodating cavity. The second accommodating cavity serves as the first protection against milk seepage in the first accommodating cavity to prevent milk from seeping into the third accommodating cavity; the sucking holes are arranged in a regular or irregular manner to ensure smooth flow of the milk.

The first clamping part 106 is used for installing the sucking body 101 in the installation hole 203. Through the clamping of the first clamping part, the sucking part 100 can be stably and tightly installed on the fitting seat 200, and neither air leakage nor milk leakage from the connection will occur.

The portion between the upper and lower end surfaces of the mounting hole 203 will form a clamping protrusion, that is, a clamping platform, which will be clamped in the clamping groove to achieve a sealed connection installation.

The nipple-shaped sucking head 102 simulates the mother's nipple, which can arouse the child's interest and arouse the child's desire to drink milk on the one hand, and can also make it more convenient for the child to suck on the other hand; the nipple-shaped first accommodating cavity 104 can better accommodate the mother's nipple for mothers with protruding nipples, so that the child can suck better. For mothers with sunken nipples, the first accommodating cavity of this shape will be able to better accept the child's sucking force, so that the milk inside can be quickly eaten by the child.

The second clamping portion 208 is specifically used to cooperate with the first clamping portion 106 on the sucking portion 100, so that the sucking portion can be stably and tightly mounted on the fitting seat 200, and neither air leakage nor milk leakage from the connection will occur. In order to ensure better sealing, a sealing ring can be separately provided at the connection between the second clamping portion and the first clamping portion to better ensure sealing.

The structure in which the snap-fitting protrusion and the snap-fitting groove cooperate with each other is not only simple in structure but also has good sealing performance. It is suitable for breastfeeding products such as the breastfeeding aid in the present invention that have high requirements for simple structure and ease of use. When the first snap-fitting portion 106 is set as a snap-fitting protrusion, the second snap-fitting portion 208 will be correspondingly set as a snap-fitting groove structure, and when the first snap-fitting portion is set as a snap-fitting groove, the second snap-fitting portion will be correspondingly set as a snap-fitting protrusion structure.

The fitting surface 206 is designed to be a curved surface that matches the breast skin, on the one hand to increase the comfort for the mother, and on the other hand to ensure the tightness after fitting. Only when the shape of the fitting surface matches the mother's breast skin can it fit more closely and firmly under the action of negative pressure.

Multiple negative pressure holes 207 can be arranged in groups, for example, each group is composed of two, three or four waist-shaped holes in parallel, and multiple groups of waist-shaped holes are evenly arranged at equal intervals on the fitting surface 206; the shape of the negative pressure holes is not limited to the shape of waist-shaped holes, and can also be set to various shapes such as square, circle, triangle, irregular polygon, snowflake or cartoon. The number, shape and arrangement of the negative pressure holes are based on the fact that the fitting seat can be stably fitted on the breast and the generated adsorption force will not make the breast feel pain. It can be flexibly designed according to actual conditions.

The excessive arc can increase the comfort of fitting on the mother's breast, and will not give the mother's breast an uncomfortable feeling at the connection. The excessive arc can also increase the tightness of the fit, which can prevent air leakage and milk leakage.

The sucking portion 100 is an integrally formed structure, which is easy to process and manufacture, and can be manufactured directly using a mold, and can be manufactured separately as an accessory.

The fitting seat 200 is an integrally formed structure, which is easy to process and manufacture, and can be directly manufactured using a mold, and can be manufactured separately as an accessory.
