Description

Technical Field

[0001] The utility model relates to maternal and infant products, in particular to a nipple shield. Background Art

[0002] Breastfeeding is a natural way to feed infants. During breastfeeding, the infant holds the mother's nipple in the mouth and squeezes the milk out of the mother's breast by wriggling the tongue. That is to say, during the process of feeding the infant, the mother's nipple is stressed, which is likely to cause nipple chapping, bringing discomfort and pain to the mother, and even causing nipple injury in severe cases. For this reason, the nipple shield was invented. For example, a nipple shield is disclosed in a Chinese utility model patent with the authorization publication number of CN219230782U, which includes a nipple and a protective cover. The nipple is arranged at the top of the protective cover and is communicated with the inside of the protective cover. The top of the nipple is provided with a milk outlet. The protective cover is conical. The nipple is inclined to one side and is arranged at an acute angle with the central axis of the bottom edge of the protective cover. When in use, the mother attaches the nipple shield to the breast and covers the nipple. The infant sucks milk by holding the nipple of the nipple shield in the mouth. In this way, the nipple shield isolates the breast and the infant's oral cavity, avoiding the above problems. The existing nipple shield uses the tilted head design of the nipple, expecting the mother to conveniently adjust the suitable angle for convenient breastfeeding. However, the tilting direction and tilting angle of the nipple of the existing nipple shield are both fixed. When the mother attaches the existing nipple shield to the breast, she needs to pay special attention to the orientation of the nipple, and during the breastfeeding process, she needs to pay special attention to the sucking posture of the infant.

That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0040] Those skilled in the art should understand that the embodiments of the present utility model described above and shown in the drawings are only examples and do not limit the present utility model. The object of the present utility model has been fully and effectively achieved. The functions and structural principles of the present utility model have been demonstrated and explained in the embodiments. Without departing from the said principles, the embodiments of the present utility model can have any deformation or modification.

[0041] Referring to the appended Figures 1 to 9 drawings of the specification of the present utility model, a nipple protector according to a preferred embodiment of the present utility model will be disclosed and described hereinafter. The nipple protector includes an inlet portion 10, a deformable shoulder portion 20, a fitting base portion 30 and has a cavity 40. The inlet portion 10, the shoulder portion 20 and the fitting base portion 30 are of an integral structure, and the inlet portion 10, the shoulder portion 20 and the fitting base portion 30 together form the cavity 40.

[0042] Specifically, the inlet portion 10, the shoulder portion 20, and the fitting base portion 30 are integrally made of an elastic material. For example, a silicone material can be used to integrally make the inlet portion 10, the shoulder portion 20, and the fitting base portion 30. The shoulder portion 20 integrally extends outward from the bottom side of the inlet portion 10, and the fitting base portion 30 integrally extends downward from the outer side of the shoulder portion 20. The inlet portion 10, the shoulder portion 20, and the fitting base portion 30 define the cavity 40, and the fitting base portion 30 forms an opening 41 of the cavity 40. The inlet portion 10 has a liquid drainage channel 11, and the liquid drainage channel 11 communicates with the cavity 40. The fitting base portion 30 is used to fit the nipple shield to the position of the mother's breast and allow the nipple to be received in the cavity 40 of the nipple shield. When the inlet portion 10 is pulled laterally, the inlet portion 10 can deform the shoulder portion 20 and allow the inlet portion 10 to swing laterally, thereby adjusting the orientation and angle of the inlet portion 10, where "laterally" refers to the direction perpendicular to the extending direction of the inlet portion 10. Preferably, the shape and size of the inlet portion 10 are consistent with those of the nipple so that the inlet portion 10 simulates the nipple for soothing infants and young children.

[0043] When the mother wears the nipple shield, the nipple is received in the cavity 40 of the nipple shield, and the breast can close the opening 41 of the nipple shield. When the infant sucks milk with the nipple shield in its mouth at the inlet portion 10, on the one hand, the milk discharged from the mother's breast reaches the infant's oral cavity through the liquid discharge channel 11 of the inlet portion 10 and is swallowed by the infant. On the other hand, the air in the cavity 40 of the nipple shield is discharged, creating a negative pressure environment in the cavity 40 to help the mother wear the nipple shield stably and prevent the nipple shield from falling off the breast. Moreover, the shape of the fitting base 30 can change according to the shape of the breast, enabling the fitting base 30 to be reliably attached to the breast, thus helping the mother wear the nipple shield stably. On the one hand, when the mother adjusts the feeding posture for the infant, the infant pulls the inlet portion 10 horizontally, and the inlet portion 10 pulls the shoulder portion 20, deforming the shoulder portion 20 to allow the orientation and angle of the inlet portion 10 to be adaptively adjusted to the state of the mother's feeding posture for the infant. On the other hand, during the process of the mother feeding the infant, even if the mother adjusts the feeding posture, the orientation and angle of the inlet portion 10 will automatically change with the change of the mother's feeding posture, so that the orientation and angle of the inlet portion 10 are adaptively adjusted to the state of the mother's feeding posture for the infant. That is to say, during the process of the mother feeding the infant, the mother does not need to take out the inlet portion 10 of the nipple shield from the infant's mouth to adjust the feeding posture, and during the process of the mother adjusting the feeding posture, the orientation and angle of the inlet portion 10 automatically change and are adaptively adjusted to the state of the mother's feeding posture for the infant.

[0044] That is to say, when the mother wears the nipple shield, she does not need to pay attention to the orientation of the inlet portion 10. When the infant sucks the inlet portion 10 and pulls it horizontally, both the orientation and angle of the inlet portion 10 can be adaptively adjusted to the state of the mother's feeding posture for the infant, which is crucial for the mother to conveniently feed the infant with the help of the nipple shield and for the mother to comfortably feed the infant with the help of the nipple shield.

[0045] In an embodiment of the nipple shield of the present invention, the nipple shield further includes at least one mouth reinforcing rib 50. The mouth reinforcing rib 50 is integrally formed on the inlet portion 10 and is located in the cavity 40. The mouth reinforcing rib 50 is used to enhance the structural strength of the inlet portion 10, enabling the inlet portion 10 to maintain the shape of the nipple and not be easily damaged, so that the inlet portion 10 simulates the nipple and extends the service life of the nipple shield. In a specific example, refer to the attached Figures 3 to 6, the mouth reinforcing rib 50 is annular, and the two mouth reinforcing ribs 50 are arranged at intervals. Optionally, in other examples of the nipple shield of the present invention, the mouth reinforcing rib 50 extends spirally along the extending direction of the inlet portion 10. In this way, when the infant bites the inlet portion 10 flat, the mouth reinforcing rib 50 can prevent the inner walls of the inlet portion 10 from sticking together, which is beneficial for the inlet portion 10 to return to its initial state (papillary).

[0046] In a specific example of the nipple shield of the present invention, referring to the attached Figures 3 to 6 , the shoulder portion 20 extends integrally downward from the bottom side of the inlet portion 10, so that the shoulder portion 20 extends obliquely between the inlet portion 10 and the fitting base portion 30, wherein the fitting base portion 30 extends integrally outward from the outer side of the shoulder portion 20, so that the fitting base portion 30 extends obliquely from the shoulder portion 20. That is to say, in this specific example of the nipple shield of the present invention, the shoulder portion 20 extends integrally outward and downward from the bottom side of the inlet portion 10, so that the shoulder portion 20 is conical, and the fitting base portion 30 extends integrally downward and outward from the outer side of the shoulder portion 20, so that the fitting base portion 30 is conical. In this way, the shape of the cavity 40 of the nipple shield can match the shape of the breast, so that the nipple shield can be stably worn by the mother and ensure wearing comfort.

[0047] In an example of the nipple shield of the present invention, the thickness dimension of the shoulder portion 20 is smaller than the thickness dimension of the portion of the inlet portion 10 adjacent to the shoulder portion 20, and the thickness dimension of the shoulder portion 20 is smaller than the thickness dimension of the portion of the fitting base portion 30 adjacent to the shoulder portion 20. That is to say, compared with the portion of the inlet portion 10 adjacent to the shoulder portion 20 and the portion of the fitting base portion 30 adjacent to the shoulder portion 20, the shoulder portion 20 is thinner. In this way, during the process of the mother feeding the infant with the nipple shield, when the infant laterally pulls the inlet portion 10, the shoulder portion 20 is easily deformed, so that the orientation and angle of the inlet portion 10 are adjusted. During this process, the infant is unaware, so as to ensure the comfort of the infant during the feeding process. In other words, after the shoulder portion 20 is deformed due to the infant laterally pulling the inlet portion 10, the restoring force generated by the shoulder portion 20 is smaller. In this way, it is not easy for the infant to feel the reverse force provided by the inlet portion 10 to the inner wall of the oral cavity, so that the infant is unaware, so as to ensure the comfort of the infant during the feeding process.

[0048] In an example of the nipple protector of the present utility model, the nipple protector further includes at least one shoulder reinforcing rib 60, which is integrally formed on the shoulder 20. The shoulder reinforcing rib 60 is used to reinforce the strength of the shoulder 20, so that the shoulder 20 can support the inlet portion 10 on the basis of being easily deformed, and prevent the inlet portion 10 from deforming the shoulder 20 under its own gravity. In other words, by integrally forming the shoulder reinforcing rib 60 on the shoulder 20, the posture of the nipple protector can be kept stable without external force acting on the inlet portion 10.

[0049] In the Figures 1 to 9 specific example of the nipple protector of the present utility model shown in the attached figure, the shoulder reinforcing rib 60 is formed in a ring shape on the outer side of the shoulder 20, and from a top-down perspective, the shoulder reinforcing rib 60 surrounds the inlet portion 10. In this way, when the mother wears the nipple protector, the shoulder reinforcing rib 60 will not contact the mother's skin, so as to ensure the comfort of the mother when wearing.

[0050] It is worth mentioning that the number of the shoulder reinforcing ribs 60 is not limited in the nipple protector of the present utility model. For example, in the Figures 1 to 9 specific example of the nipple protector of the present utility model shown in the attached figure, the number of the shoulder reinforcing ribs 60 is two, and the two shoulder reinforcing ribs 60 are concentrically arranged. That is to say, one shoulder reinforcing rib 60 is located on the inner side and one shoulder reinforcing rib 60 is located on the outer side, so that the two shoulder reinforcing ribs 60 are concentrically arranged.

[0051] Optionally, in the Figure 10 deformation example of the nipple protector of the present utility model shown in the attached figure, the extending direction of the shoulder reinforcing rib 60 is the same as that of the shoulder 20. A group of shoulder reinforcing ribs 60 are arranged in a ring shape on the outer side of the shoulder 20, and from a top-down perspective, a group of shoulder reinforcing ribs 60 surround the inlet portion 10. In this way, when the mother wears the nipple protector, the shoulder reinforcing rib 60 will not contact the mother's skin, so as to ensure the comfort of the mother when wearing. In the Figure 10 specific example of the nipple protector of the present utility model shown in the attached figure, the nipple protector includes two groups of shoulder reinforcing ribs 60, one group of shoulder reinforcing ribs 60 is located on the inner side and the other group of shoulder reinforcing ribs 60 is located on the outer side.

[0052] Continue to refer to the attached Figures 1 to 9, the nipple shield further includes a shield 70 which extends integrally outward from a portion of the inlet portion 10 adjacent to the shoulder portion 20, and from a top-down perspective, the shield 70 covers at least a part of the shoulder portion 20. In this way, when an infant sucks on the inlet portion 10 while breastfeeding, the shield 70 can isolate the shoulder portion 20 from the infant's mouth, preventing the shoulder portion 20 from rubbing against the infant's mouth during continuous deformation, thus ensuring the comfort of the infant during breastfeeding. Preferably, the shield 70 extends integrally outward and downward from a portion of the inlet portion 10 adjacent to the shoulder portion 20, so that the shield 70 covers at least a part of the shoulder portion 20 in an "umbrella" shape. In particular, the portion of the shoulder portion 20 where the shoulder reinforcing rib 60 is provided is covered by the shield 70. Thus, on the one hand, the shield 70 makes the shoulder reinforcing rib 60 visually invisible, which is beneficial to improving the aesthetics of the nipple shield; on the other hand, the shield 70 prevents the infant's mouth from coming into contact with the shoulder reinforcing rib 60, improving the comfort of the infant during breastfeeding.

[0053] In a specific example of the nipple shield of the present utility model, an avoidance space 80 and an avoidance opening 90 surrounding the avoidance space 80 are formed between the shield 70 and the shoulder portion 20 of the nipple shield, that is, the shield 70 and the shoulder portion 20 do not come into direct contact, avoiding the problem that the shield 70 affects the deformation of the shoulder portion 20. That is to say, the setting of the shield 70 can not only isolate the infant's mouth from the shoulder portion 20, preventing the shoulder portion 20 from rubbing against the infant's mouth during continuous deformation, but also does not affect the deformation of the shoulder portion 20, enabling the orientation and angle of the inlet portion 10 to be flexibly adjusted to adapt to the mother's breastfeeding posture for the infant. In addition, the inlet portion 10, the fitting base portion 30 and the shield 70 form the general appearance of the nipple shield. By setting the shield 70 and covering the shoulder portion 20 with the shield 70, it is beneficial to improve the aesthetics of the nipple shield.

[0054] Refer to the attached Figure 4 and Figure 7 , in a specific example of the nipple shield of the present utility model, the distance L1 between the outer edge of the shield 70 and the central axis of the nipple shield is less than the distance L2 between the top of the fitting base portion 30 and the central axis. In this way, the shield 70 will not affect the upward turning of the fitting base portion 30, facilitating the mother to wear the nipple shield.

[0055] Refer to the attached Figures 1 to 3 , Figure 5 and Figure 6, the nipple shield further includes at least one soothing portion 100, the soothing portion 100 is disposed on the shield 70, and the soothing portion 100 protrudes toward the inlet portion 10, wherein the soothing portion 100 is used to simulate the Montgomery's tubercles of the mother's areola. When the infant sucks milk through the nipple shield, the soothing portion 100 can stimulate the touch and vision of the infant to help the infant adapt to the nipple shield more quickly. Preferably, the number of the soothing portions 100 of the nipple shield is plural, and these soothing portions 100 are arranged annularly around the inlet portion 10. More preferably, the soothing portion 100 is formed by a group of convex points.

[0056] Reference attachment Figure 7 and Figure 8 , before the mother wears the nipple shield, the fitting base 30 can be turned up first. Since the thickness dimension of the portion of the fitting base 30 adjacent to the shoulder 20 is greater than the thickness dimension of the shoulder 20, and the distance L1 between the outer edge of the shield 70 and the central axis of the nipple shield is less than the distance L2 between the top of the fitting base 30 and the central axis of the nipple shield, after turning up the fitting base 30, the fitting base 30 and the shield 70 do not contact, avoiding the shield 70 pushing the fitting base 30 outwards, so that the fitting base 30 can be kept in the turned-up state. The purpose of turning up the fitting base 30 is to facilitate the alignment of the inlet portion 10 with the nipple. After the mother attaches the nipple shield to the breast with the inlet portion 10 aligned with the nipple, turn over the fitting base 30 so that the inner wall of the fitting base 30 fits the breast, and thus the mother wears the nipple shield on the breast. It can be understood that when the mother wears the nipple shield, she can also not turn up the fitting base 30.

[0057] Reference attachment Figure 9, when an infant holds the inlet part 10 in the mouth and nurses, on the one hand, the milk discharged from the mother's breast reaches the infant's oral cavity through the liquid discharge channel 11 of the inlet part 10 and is swallowed by the infant. On the other hand, the air in the cavity 40 of the nipple shield is discharged, creating a negative pressure environment in the cavity 40 to help the mother wear the nipple shield stably and prevent the nipple shield from falling off the breast. On the one hand, when the mother adjusts the feeding posture of the infant, the infant pulls the inlet part 10 horizontally, and the inlet part 10 pulls the shoulder part 20 to deform the shoulder part 20, allowing the orientation and angle of the inlet part 10 to be adaptively adjusted to the state of the mother's feeding posture of the infant. On the other hand, during the process of the mother feeding the infant, even if the mother adjusts the feeding posture, the orientation and angle of the inlet part 10 will automatically change with the change of the mother's feeding posture, so that the orientation and angle of the inlet part 10 are adaptively adjusted to the state of the mother's feeding posture of the infant.

[0058] Appendix Figures 11 to 13 shows a deformation example of the nipple shield according to the above-mentioned preferred embodiment of the present invention. Different from the nipple shield shown in the appendix Figures 1 to 9 shown, in this specific example of the nipple shield shown in the appendix Figures 11 to 13 shown, the nipple shield further includes a one-way valve 110, which is integrally formed on the fitting base 30. When the mother wears the nipple shield and a negative pressure environment is formed in the cavity 40 of the nipple shield, the one-way valve 110 is arranged to restore the cavity 40 of the nipple shield to normal pressure, enabling the mother to conveniently remove the nipple shield from the breast.

[0059] Furthermore, the fitting base 30 has an exhaust channel 31, which communicates with the cavity 40. The one-way valve 110 is arranged to be able to open or close the exhaust channel 31 of the fitting base 30. When the one-way valve 110 opens the exhaust channel 31 of the fitting base 30, the air in the cavity 40 of the nipple shield is allowed to be discharged to the external environment through the one-way valve 110 and the exhaust channel 31 of the fitting base 30. In this way, a negative pressure environment is formed in the cavity 40 of the nipple shield, enabling the nipple shield to be reliably worn at the breast position.

[0060] In an example of the nipple protector of the present utility model, the one-way valve 110 includes a first valve piece 1101 and a second valve piece 1102. The first valve piece 1101 and the second valve piece 1102 respectively extend integrally and obliquely from opposite sides of the exhaust passage 31 of the fitting base 30. And in the natural state, the ends of the first valve piece 1101 and the second valve piece 1102 are in contact with each other to close the exhaust passage 31 of the fitting base 30 by the first valve piece 1101 and the second valve piece 1102. When the mother uses her finger to deform at least one of the first valve piece 1101 and the second valve piece 1102, a gap is generated between the ends of the first valve piece 1101 and the second valve piece 1102, so that the first valve piece 1101 and the second valve piece 1102 open the exhaust passage 31 of the fitting base 30.

[0061] Preferably, the first valve piece 1101 and the second valve piece 1102 are received in the exhaust passage 31 of the fitting base 30, so as to prevent the first valve piece 1101 and the second valve piece 1102 from protruding into the cavity 40 and affecting the comfort of the mother wearing the nipple protector, and to prevent the first valve piece 1101 and the second valve piece 1102 from protruding out of the fitting base 30 and causing misoperation of the one-way valve 110.

[0062] Optionally, in other examples of the nipple protector of the present utility model, the one-way valve 110 is installed on the fitting base 30.

[0063] Attached Figures 14 to 16 shows a deformed example of the nipple protector according to the above preferred embodiment of the present utility model. Different from the nipple protector shown in Attached Figures 1 to 9 shown, in this specific example of the nipple protector shown in Attached Figures 14 to 16 shown, the nipple protector includes a set of anti-sticking protrusions 120. These anti-sticking protrusions 120 extend spirally and at intervals along the extending direction of the inlet portion 10 to form an anti-sticking groove 130 between two adjacent anti-sticking protrusions 120. In this way, when the infant bites the inlet portion 10 flat, the anti-sticking protrusions 120 and the anti-sticking groove 130 can prevent the inner wall of the inlet portion 10 from sticking, which is beneficial to the inlet portion 10 to recover to its initial state (papillary shape).

[0064] Those skilled in the art should understand that the embodiments of the present utility model described above and shown in the drawings are only examples and do not limit the present utility model. The object of the present utility model has been fully and effectively achieved. The functions and structural principles of the present utility model have been shown and described in the embodiments. Without departing from the principle, the embodiments of the present utility model can have any deformation or modification.
