Some mothers also have problems with inverted nipples and cannot breastfeed smoothly. The advent of products such as nipple shields (milk shields) is to solve the above problems. However, most of the existing products on the market are single-layer structures, that is, they only have a human-like protective shield and a front receiving cavity structure. However, due to the differences in human bodies, such a structural design generally leads to poor fit, and it only has 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 protective shield.

[0003] The utility model is proposed in view of the deficiencies in the prior art. Utility Model Content

[0024] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 As shown, the nipple protection shield of this embodiment includes a shield body 1 and a shield 2. The shield body 1 includes a fitting portion 11 and a mouthpiece 12. The shield 2 is arranged around the outside of the mouthpiece 12. The shield 2 can limit the position of the newborn baby biting on the mouthpiece 12. A buffer zone 3 is arranged between the shield 2 and the fitting portion 11. The buffer zone 3 is used for the mouthpiece 12 and the shield 2 to swing. A fitting cavity 101 is arranged on the inner side of the fitting portion 11. The mouthpiece 12 has a A front cavity 103 and a receiving cavity 102 are provided inside, the receiving cavity 102 is located between the front cavity 103 and the fitting cavity 101, and is communicated with the front cavity 103 and the fitting cavity 101 respectively, the nozzle portion 12 is provided with a liquid outlet 104 communicated with the front cavity 103, the bottom of the nozzle portion 12 is provided with an annular auxiliary fitting cover body 4 extending into the fitting cavity 101, and a deformation gap 41 is provided between the outer side wall of the annular auxiliary fitting cover body 4 and the inner side wall of the fitting cavity 101,

[0026] Specifically, when the nipple shield is adsorbed on the breast, the fitting portion 11 and the annular auxiliary fitting cover body 4 are elastically deformed, and the inner side wall of the fitting portion 11 and the inner side wall of the annular auxiliary fitting cover body 4 are tightly attached to the breast, more closely fitting the breast, and adaptively adapting to the shape and size changes of the breast to eliminate the gap between the bottom end of the accommodating cavity 102 and the breast, providing additional sealing effect, and further improving the fit of the nipple shield, and the nipple passes through the annular auxiliary fitting cover body 4 and extends into the accommodating cavity 102, and the newborn bites on the outer side wall of the front cavity 103 of the suction nozzle portion 12, and the newborn bites on the position of the newborn by the shield 2 to prevent the newborn from accidentally biting the nipple, thereby reducing breastfeeding pain.

[0027] Specifically, the elastic deformation between the fitting portion and the annular auxiliary fitting shield body can ensure that the shield body fits closely to the breast, reducing the gap between the breast and the shield body and providing an additional sealing effect. This adaptability ensures that it can be effectively used on breasts of different shapes and sizes, helping to keep milk flowing to the baby and preventing milk from leaking between the nipple shield and the breast.

[0028] In addition, the setting of the shield can effectively limit the newborn's biting position and protect the nipple from accidental biting.

[0029] like Figures 1 to 5 As shown, a deformation groove 42 is provided at the connection between the fitting portion 11 and the nozzle portion 12 of this embodiment, and the deformation groove 42 is arranged on the outer side of the annular auxiliary fitting cover body 4, and the deformation groove 42 is communicated with the deformation gap 41;

[0030] Specifically, the deformation groove 42 has a side opening and a bottom opening. During the deformation process of the annular auxiliary fitting cover body 4, the connection between the bottom of the suction nozzle 12 and the annular auxiliary fitting cover body 4 can enter the deformation groove 42, thereby increasing the deformation amount of the annular auxiliary fitting cover body 4, thereby increasing the contact surface area between the annular auxiliary fitting cover body 4 and the breast, and further improving the sealing performance.

[0031] like Figures 1 to 5 As shown, the maximum inner diameter of the annular auxiliary fitting cover body 4 of this embodiment is slightly larger than the maximum inner diameter of the accommodating cavity 102. With such a design, the annular auxiliary fitting cover body 4 is specifically used to fit with the areola, and accurately and efficiently fits the surrounding area of ​​the areola. This design ensures that the annular auxiliary fitting cover body 4 mainly fits with the areola rather than most of the surface of the breast. The fit around the areola is more critical because it can help keep the nipple in the correct position of the suction mouth, thereby promoting effective sucking and reducing milk leakage.

[0032] Furthermore, by making the diameter of the annular auxiliary fitting shield body 4 slightly larger than the inner diameter of the accommodating cavity, it is possible to effectively avoid excessive compression of the breast caused by an excessively large adsorption area of ​​the annular auxiliary fitting shield body 4. This careful design can reduce discomfort when wearing, making it easier and more comfortable to continue using the nipple shield. Furthermore, the annular auxiliary fitting shield body 4 can limit the milk in the accommodating cavity 102 to the areola position. When the newborn sucks milk at a slower speed, it ensures that the milk is concentrated inside the accommodating cavity 102 instead of overflowing to other parts of the breast. This effectively limits the diffusion of milk on the surface of the breast, prevents the milk from flowing to other parts of the breast, reduces moisture and stickiness, and improves the overall comfort of the mother when using the nipple shield. Furthermore, the accommodating cavity is made to a more suitable size, so that milk is more likely to gather inside the accommodating cavity, which will provide a stable source of milk for the newborn, so that when the baby's sucking speed increases, the milk supply can respond quickly, thereby improving feeding efficiency.

[0033] Furthermore, the precise size design enables the annular auxiliary fitting cover body 4 to form a better seal when in contact with the areola. Good sealing can not only reduce milk leakage, but also improve milk suction efficiency, making it easier for the baby to obtain milk when sucking.

[0034] Furthermore, the slightly larger inner diameter design of the annular auxiliary fitting cover body 4 also means that the annular auxiliary fitting cover body 4 can adapt to a wider range of areola sizes, thereby improving the versatility and flexibility of the product, which enables the same product to meet the needs of more mothers without having to worry too much about size matching issues.

[0035] like Figures 1 to 5 As shown, the cross-sectional shape of the annular auxiliary fitting cover body 4 of the present embodiment is trumpet-shaped so as to better adapt to areolas of different sizes and shapes. The trumpet-shaped wide mouth can better cover the skin around the areola, thereby improving the sealing performance, helping to maintain the negative pressure during milk sucking, and improving the milk sucking efficiency. The trumpet-shaped cross-sectional design may help to simulate the change in breast shape when the baby sucks, and this dynamic change can enhance the stimulation of the mammary gland and promote milk secretion. The trumpet-shaped design helps to reduce the pressure on the areola and nipple because it can expand more naturally to adapt to the shape of the breast, which can reduce discomfort during long-term feeding or milk sucking.

[0036] like Figures 1 to 5 As shown, the thickness of the annular auxiliary fitting mask body 4 of this embodiment gradually becomes thinner from top to bottom, and the thicker upper part can provide better support and ensure the structural strength between the annular auxiliary fitting mask body 4 and the suction nozzle part 12, while the gradually thinning lower part can allow the annular auxiliary fitting mask body 4 to have better fit and softness to adapt to different shapes and sizes of breasts.

[0037] Furthermore, the thinner lower portion of the annular auxiliary fitting cover body 4 reduces the pressure on the breast, reduces the discomfort during use, and makes the mother feel more comfortable during feeding.

[0038] Furthermore, the gradually thinning design of the annular auxiliary fitting cover body 4 helps to simulate the natural shape changes of the breast when the baby sucks milk, which helps the flow and extraction of milk.

[0039] like Figures 1 to 5 As shown, the shield 2 of this embodiment is located outside the accommodating cavity 102 , or outside the connection between the accommodating cavity 102 and the front cavity 103 .

[0040] Preferably, the shield 2 is in an umbrella shape and extends outward along the outer side wall of the suction nozzle 12, and the lower part of the shield 2 is set as a buffer zone 3. In actual use, the cover body 1 is adsorbed on the human nipple by negative pressure, the fitting part 11 and the annular auxiliary fitting cover body 4 are tightly attached to the breast skin, and the nipple extends into the accommodating cavity 102 through the annular auxiliary fitting cover body 4. The breast and the nipple are wrapped by the cover body 1, and the newborn bites on the outer side wall of the front cavity 103 of the suction nozzle 12, and the position of the newborn bite is limited by the shield 2 to avoid the newborn from accidentally biting the nipple, thereby reducing breastfeeding pain, and negative pressure is generated inside the cover body 1 through the sucking action of the newborn, so that the cover body 1 is deformed and squeezes the breast to produce milk, and as the newborn sucks, the milk flows into the mouth of the newborn through the front cavity 103 and the liquid outlet 104 in sequence.

[0041] Since the newborn is very young, it is inevitable that the newborn's head and body will move around when sucking milk. Therefore, a buffer zone 3 is provided on the nipple protection shield, and the buffer zone 3 is located between the shield 2 and the fitting portion 11. When the newborn bites the suction nozzle 12, the buffer zone 3 can make the suction nozzle 12 and the shield 2 swing relative to the fitting portion 11 along with the movement of the newborn's head. At this time, the fitting portion 11 is still tightly attached to the human skin to prevent the shield body 1 from being easily pulled on the nipple or easily falling off due to the excessive movement of the newborn, thereby reducing breastfeeding pain and improving the comfort of the human body during breastfeeding.

[0042] In addition, a reinforcing rib 121 is provided on the inner side of the suction nozzle portion 12, and the reinforcing rib 121 extends radially inward along the inner wall of the front cavity 103. A plurality of reinforcing ribs 121 may be provided to enhance the structural strength of the wall of the front cavity 103, so that the suction nozzle portion 12 is not easily damaged and the service life of the cover body 1 is extended.

[0043] like Figures 1 to 5 As shown, the buffer zone 3 of this embodiment includes a buffer connection section 31 and a buffer gap 32. The buffer connection section 31 is the bottom side portion of the nozzle portion 12. The buffer connection section 31 is located between the shield 2 and the fitting portion 11. The buffer gap 32 is formed between the bottom side of the shield 2 and the outer side wall of the fitting portion 11.

[0044] Preferably, the arc height of the cross-sectional surface of the shield 2 is higher than the arc height of the outer side wall of the fitting portion 11 .

[0045] In this embodiment, the buffer connecting section 31 is the portion of the cover body 1 located below the shield 2, and the buffer connecting section 31 can be understood as the bottom side portion of the nozzle portion 12. The buffer connecting section 31 extends upward from the top of the fitting portion 11 and is connected to the connection between the shield 2 and the nozzle portion 12. The shield 2 is preferably umbrella-shaped, and the curvature of the shield 2 is similar to the curvature of the top wall of the fitting portion 11, which is beneficial to improving the overall aesthetics of the nipple protector. The shield 2 is spaced relative to the top wall of the fitting portion 11 and forms the buffer gap 32.

[0046] In actual use, the buffer connection section 31 can enable the suction nozzle portion 12 and the shield 2 to swing at an angle relative to the fitting portion 11 to prevent the shield body 1 from being easily pulled on the nipple or easily falling off due to the excessive movement of the newborn, thereby reducing breastfeeding pain and improving the comfort of the human body during breastfeeding. It can also enable the newborn to better use the nipple shield and improve the flexibility of use of the nipple shield. The buffer gap 32 provides a swinging space for the shield 2, and the buffer zone 3 has a simple structure and is easy to produce and implement.

[0047] Preferably, the outer side wall of the fitting portion 11 is provided with anti-slip grooves 111 opposite to the shield 2. In this embodiment, the outer top wall of the fitting portion 11 is provided with anti-slip grooves 111, and the anti-slip grooves 111 are preferably wave grooves arranged along the outer top wall of the fitting portion 11, which are easy to produce and implement; when the shield 2 swings with the movement of the newborn's head, the anti-slip grooves 111 prevent the shield 2 from being attached to the fitting portion 11, so as to ensure the free swing of the shield 2.

[0048] like Figures 1 to 5 As shown, the outer contour of the front cavity 103 of this embodiment is set to be nipple-shaped, the outer wall of the front cavity 103 is connected to the outer wall of the accommodating cavity 102 through a concave arc segment 112, and the front cavity 103 gradually becomes thinner along the direction close to the accommodating cavity 102.

[0049] In this embodiment, the suction nozzle portion 12 also includes an outer wall of the front cavity 103, an outer wall of the concave arc segment 112 and an outer wall of the accommodating cavity 102. The concave arc segment 112 is used for the newborn to bite. The outer wall of the front cavity 103 and the outer wall of the accommodating cavity 102 are connected by the concave arc segment 112 to facilitate a smooth transition between the outer wall of the front cavity 103 and the outer wall of the accommodating cavity 102, so as to improve the comfort of the newborn when sucking milk.

[0050] By setting the outer contour of the front cavity 103 to be nipple-shaped, the front cavity 103 gradually becomes thinner along the direction close to the accommodating cavity 102, which can simulate the nipple, allowing the newborn to adapt to the nipple protection shield more easily when sucking milk, thereby improving the comfort and success rate of breastfeeding, and also helping to protect the nipple.

[0051] Preferably, the inner walls of the fitting cavity 101, the annular auxiliary fitting cover body 4 and the accommodating cavity 102 are all arranged to be smooth surfaces. In the present embodiment, the fitting portion 11 and the annular auxiliary fitting cover body 4 are used to fit the breast, and the nipple passes through the annular auxiliary fitting cover body 4 and extends into the accommodating cavity 102. By arranging smooth inner walls in the fitting portion 11, the annular auxiliary fitting cover body 4 and the suction nozzle portion 12, it is beneficial to improve the fit between the inner walls of the fitting portion 11, the annular auxiliary fitting cover body 4 and the suction nozzle portion 12 and the skin, thereby making the nipple protection cover not easy to fall off, thereby improving the comfort and efficiency of breastfeeding.

[0052] like Figures 1 to 5 As shown, the accommodating chamber 102 of the present embodiment gradually widens from the top end connected to the front chamber 103 toward the bottom end connected to the fitting chamber 101, and an extension portion 122 is provided between the accommodating chamber 102 and the fitting chamber 101, and the extension portion 122 extends radially inward from the connection between the inner wall of the fitting portion 11 and the inner wall of the nozzle portion 12.

[0053] In this embodiment, the accommodating chamber 102 is preferably set as a pear-shaped chamber, so that the internal space of the accommodating chamber 102 can be adapted to the nipple, thereby improving human comfort; in the actual breastfeeding process, the inside of the cover body 1 generates negative pressure due to the sucking of the newborn, and the nipple is squeezed by the cover body 1 to produce milk, and the milk has the phenomenon of flowing back along the nipple. The extension part 122 is stuck on the outside of the nipple to form a sealed and leak-proof milk structure, and a double sealing structure is formed with the annular auxiliary fitting cover body 4, so that the milk can be temporarily stored in the accommodating chamber 102 but will not flow back, and the milk backflow is prevented to reduce the fit between the fitting part 11 and the annular auxiliary fitting cover body 4 and the human skin, causing the nipple protection cover to fall off easily, thereby keeping the breasts clean during breastfeeding.

[0054] like Figures 1 to 5 As shown, the bottom structure of the fitting portion 11 of this embodiment is wavy.

[0055] Specifically, the traditional smooth bottom design exerts greater pressure on the breasts, while the wavy design can distribute this pressure more evenly and reduce local discomfort.

[0056] Furthermore, the wavy bottom design makes it easy for the user to lift a portion of the bottom of the fitting portion 11, so that a tiny air passage is naturally formed between the fitting portion 11 and the breast, breaking the vacuum state and facilitating disassembly.

[0057] And because the wavy edges are easy to grip, users can remove the protective shield from the breast more smoothly without excessive force, which helps avoid discomfort or damage to the breast.

[0058] Specifically, the wavy edge can also help the user control the movement and direction of disassembly, making the disassembly action more precise and gentle.

[0059] Preferably, a plurality of comfort points 21 are provided on one side of the shield 2 away from the buffer zone 3; further, a plurality of the comfort points 21 are provided and are circumferentially evenly spaced on the top surface of the shield 2, so that the comfort points 21 help the newborn to better adapt to the nipple shield and reduce the discomfort when using the nipple shield, and the comfort points 21 can also stimulate the newborn's sense of touch and vision, help the newborn to better recognize his mother and breast milk, and improve the newborn's breastfeeding experience; further preferably, in order to improve the aesthetics of the nipple shield, a plurality of smaller comfort points 21 can be provided at each comfort point 21, and each small comfort point 21 can be combined and arranged to form different patterns, such as flower patterns, to enhance product competitiveness.

[0060] Preferably, the cover body 1 and the shield 2 are an integrally formed structure. In this embodiment, the cover body 1 and the shield 2 are preferably made of a flexible liquid silicone material to improve the comfort of use, and the cover body 1 and the shield 2 are integrally formed, which simplifies the production process of the nipple shield, thereby improving the production efficiency of the nipple shield, reducing its production cost, and improving the overall sealing of the nipple shield, making it less likely to leak air and liquid.

[0061] As described above, multiple implementation methods are provided in combination with specific contents, and the specific implementation of this application is not limited to these descriptions. Any similarity or similarity with the method, structure, etc. of this application, or any technical deduction or replacement made on the premise of the concept of this application, shall be deemed to be within the scope of protection of this application.
