Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of maternal and infant products, in particular to an adsorption type nipple protection cover. Background Art
[0002] Breast milk is a natural nutrition for babies. It not only provides immune factors and high-quality nutrients, but more importantly, it promotes the relationship between mother and baby. However, some mothers fail to breastfeed because of inability to secrete breast milk in time, breast diseases (inverted nipples, nipple damage), weak sucking of babies (especially premature babies), nipple confusion, etc., and have to choose other ways to breastfeed.
[0003] In order to help babies return to exclusive breastfeeding more smoothly, nipple shields (breast shields) are now available on the market to solve the above problems. For example, a nipple shield with announcement number CN210044195U includes a shield and a receiving cavity, wherein the shield serves as the main body of the shield to support and protect, and the shield includes a first shield and a second shield sleeved on the outside thereof; a first receiving cavity is formed inside the first shield, and the first receiving cavity is used to receive the nipple, and a second receiving cavity is formed between the first shield and the second shield, and the second receiving cavity is used to enhance the fit between the shield and the skin or to receive leaked lotion. This structure avoids the risk of lotion penetrating into the fitting surface through the double-layer inner wall structure, and at the same time, the micro-negative pressure in the second receiving cavity is used to increase the fit and connection strength between the product and the human body, thereby improving the use effect.
[0004] However, during the use of this product, the nipple shield is deformed and shaken due to the sucking action of the baby. After a period of sucking, the second accommodating cavity is affected by the shaking, and the sealing becomes worse, causing the negative pressure inside to decrease or even disappear, resulting in the nipple shield's fit with the human body to decrease, and even falling off the human skin surface. Therefore, when using it, it is necessary to assist with manual support or remove the nipple shield and re-attach it, which causes inconvenience in use. Utility Model Content

[0021] In order to make the present invention more clear, an absorption type nipple protection cover of the present invention is further described below with reference to the accompanying drawings. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0022] like Figure 1 As shown, a suction-type nipple protection shield is preferably made of an elastic soft material, such as liquid silicone. It includes a trumpet-shaped protection shield body 1, and a suction nozzle 2 is integrally connected to the small end (front side) of the protection shield body 1, and the suction nozzle 2 serves as the sucking part of the baby. An annular inner portion 3 and an annular outer portion 4 are integrally connected to the protection shield body 1. The annular inner portion 3 is connected to the suction nozzle 2, and its interior is connected to the interior of the suction nozzle 2 and forms a nipple accommodating cavity 5. The annular outer portion 4 is located outside the annular inner portion 3 and is integrally connected to the large end (rear side) of the protection shield body 1, and an adsorption cavity 8 is formed between the annular inner portion 3 and the annular outer portion 4. Among them, the rear side of the annular inner portion 3 has a first adsorption body 6, and the rear side of the annular outer portion 4 has a second adsorption body 7. The first and second adsorption bodies are both annular structures, and their thickness gradually increases from the edge to the inner front side, forming a suction cup-like structure. Through this structure, it is easier to seal and attach the first and second adsorption bodies to the surface of human skin.
[0023] The protective cover is also provided with a one-way valve 100 connected to the adsorption chamber 8. The one-way valve 100 has a path for one-way discharge of the gas in the adsorption chamber 8. When the protective cover body 1 is pressed, the gas in the adsorption chamber 8 is discharged through the one-way valve 100 to form a negative pressure in the chamber.
[0024] In addition, when pressing the protective cover body 1, in order to reduce the disturbance to the first and second adsorbent bodies and affect the adsorption and connection performance of the nipple protective cover, the protective cover body 1 is also provided with a pressing portion 13, which is preferably arranged at a position corresponding to the adsorption chamber 8. The pressing portion 13 may be a circular or elliptical contour suitable for single-finger pressing, or may be a contour with two opposite parts suitable for double-finger squeezing. The thickness of the pressing portion 13 is smaller than that of the protective cover body 1 in the peripheral area, making it easier to be squeezed and deformed, and the air in the adsorption chamber 8 is discharged through the one-way valve 100.
[0025] Furthermore, the protective cover body 1 is provided with a support rib 14 located around the pressing portion 13. The support rib 14 is preferably an annular support rib, so that when the pressing portion 13 is elastically deformed, the disturbance of the remaining parts of the protective cover body 1 can be reduced, thereby reducing the instability of the adsorption connection force caused by the deformation of the pressing portion.
[0026] In addition, during use, the one-way valve 100 is preferably located on the upper side of the central axis of the protective cover body 1 to prevent excess milk from overflowing from the one-way valve 100 under abnormal circumstances.
[0027] In some embodiments, the one-way valve 100 is a duckbill valve 110, which is also made of silicone and is integrally connected to the protective cover body 1. Considering the limited volume of the adsorption chamber 8, the overall volume of the duckbill valve 110 is set to be relatively small, and in order to prevent the duckbill valve 110 from interfering with the sucking action of the baby, the duckbill valve 110 is set on the side away from the suction nozzle 2.
[0028] like Figure 2 As shown, in some other embodiments, the one-way valve 100 includes an umbrella-shaped one-way valve 120 made of silicone material. As a prior art, the umbrella-shaped one-way valve 120 has an umbrella cap 121 and an umbrella handle 122 connected in one piece. The umbrella handle 122 has a limiting protrusion 123. The umbrella handle 122 is installed at the through hole 11 of the protective cover body 1 and forms an axial upward limit with the limiting protrusion 123, wherein the through hole 11 is connected to the adsorption chamber 8. When in use, a force is applied to the pressing portion 13, and the gas in the adsorption chamber 8 is discharged through the gap between the through hole 11 and the umbrella handle 122. When the applied force is withdrawn, the pressing portion 13 recovers its deformation, and the adsorption chamber 8 forms a negative pressure, which attracts the umbrella cap 121 to fit the through hole 11 to form a seal.
[0029] like Figure 3As shown, in some other embodiments, the one-way valve 100 includes a flexible diaphragm 130, one side of which is connected to the protective cover body 1 so that the flexible diaphragm 130 has an elastic opening and closing function. The specific connection method between the two can be adhesive connection, shaft + hole interference fit, one-piece injection molding, etc., which are not limited here. When the flexible diaphragm 130 is closed, it can be elastically sealed and attached to the vent 12 provided on the protective cover body 1, and the vent 12 is connected to the second adsorption chamber 8. When in use, a force is applied to the pressing part 13, and the gas in the adsorption chamber 8 pushes out the flexible diaphragm 130 through the vent 12 to discharge the gas. When the applied force is withdrawn, the pressing part 13 restores its deformation, and the flexible diaphragm 130 elastically adheres to the vent 12, while forming a negative pressure in the adsorption chamber 8.
[0030] When the device is used, first turn up the second adsorption body 7, place the nipple in the nipple receiving cavity 5, then attach the first adsorption body 6 of the device to the base of the nipple, then turn the second adsorption body 7 back to the initial state and attach it to the breast skin, and finally squeeze the pressing part 13 to discharge the gas in the adsorption cavity 8 from the one-way valve 100 to complete the attachment of the device. During use, if the device is loose or about to fall off, it is only necessary to apply squeezing force to the pressing part 13 to discharge the gas in the adsorption cavity 8 from the one-way valve 100, so that the adsorption cavity 8 can resume the negative pressure adsorption effect, further improving the continuity and stability of the adsorption connection of the device. Compared with the prior art, it does not require manual assistance and support, nor does it need to remove the nipple shield and reattach it, which improves the convenience of the device as a whole.
[0031] The above embodiments of the utility model are merely examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the utility model still belong to the protection scope of the utility model.
