Description

Technical Field

[0001] The present invention relates to the technical field of breast pumps, and specifically to a bionic sucking and massaging component and a wearable breast pump for improving lactation. Background Art

[0002] Massage for promoting lactation is a method to promote milk secretion through physical stimulation, which skillfully combines traditional Chinese medicine meridian theory and modern physiology principles. During the operation, professional masseurs use skilled techniques to stimulate the breast and surrounding acupoints. This process can effectively promote blood circulation and lymphatic return, thereby dredging the mammary ducts, enhancing the activity of mammary gland cells, and ultimately achieving the purpose of increasing the quantity and quality of milk secretion.

[0003] The techniques of massage for promoting lactation are quite particular. Usually, it is carried out by pushing and rubbing from the periphery of the breast towards the nipple direction. Such a direction design conforms to the physiological structure of the mammary gland and can better promote the flow of milk towards the nipple direction.

[0004] With the development of technology, in order to achieve the automation of promoting lactation, existing breast pumps are provided with massage components, so that massage can be carried out while sucking milk. This design aims to improve the convenience and efficiency of promoting lactation. Specifically, the air bags provided inside the breast pump will generate a certain degree of pressure on the breast when cooperating with the sucking action, thereby promoting the secretion and discharge of milk to a certain extent.

[0005] However, this air bag massage method is not perfect. Its main problem lies in the lack of accurate directionality in pressing the breast. The ideal massage direction should be from the periphery of the breast towards the nipple direction, but the pressing method of the air bag often fails to accurately achieve this direction, resulting in disordered blood and lymph flow directions. This disorder not only affects the comfort of massage, but more importantly, greatly reduces the effect of promoting lactation. Summary of the Invention

[0007] To achieve the above purpose, the present invention provides the following technical solution: A bionic sucking and massaging component for improving lactation, comprising: an inner cover, in which a plurality of groups of annular air bags with sequentially changing radii are equidistantly arranged; a connecting ring, arranged on the inner cover and communicated with the annular air bags; a switching member, hermetically and rotatably connected to the connecting ring, and two connecting positions are arranged on the switching member. When the switching member rotates, it can make two spaced annular air bags communicate with the two connecting positions and block the annular air bag in the middle. One of the two connecting positions is used for pumping pressure, and the other is used for pressure relief.

[0008] As a further solution of the present invention: the cross-section of the annular airbag includes a first side, a second side and a third side, and the first side, the second side, the third side and the inner wall of the inner cover form a closed chamber; the third side is offset toward the inner wall of the inner cover in a direction away from the first side, and the second side is arranged in an arc shape.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0030] See also Figures 1 to 10, in the embodiments of the present invention, a bionic sucking and massaging component for improving lactation includes: an inner cover 1, a connecting ring 6, and a switching member 7. By rotating the switching member 7, the annular airbags 4 can be sequentially conducted one by one, so as to generate a directional massage on the breast from the mammary gland towards the nipple. Through this massage method along the direction of the mammary ducts towards the nipple, firstly, it can effectively stimulate the flow of milk in the mammary ducts, help keep the mammary ducts unobstructed, and thus make it easier for milk to be discharged. Secondly, by pressing from the periphery of the breast towards the nipple direction, it can comprehensively stimulate the mammary tissue, promote the generation and discharge of milk, improve the overall effect of milk production, and at the same time, help push the milk towards the nipple, make the milk discharge more smoothly, relieve breast distension and hardness, and reduce the pain caused by breast engorgement in pregnant women. Specifically as follows: A plurality of groups of annular airbags 4 with sequentially changing radii are equidistantly arranged in the inner cover 1. The cross-section of the annular airbag 4 includes a first side 401, a second side 402, and a third side 403. The first side 401, the second side 402, and the third side 403 form a closed chamber with the inner wall of the inner cover 1; The third side 403 deviates towards the inner wall of the inner cover 1 along the direction away from the first side 401, so that the third side 403 is inclined relative to the inner cover 1, and the second side 402 is arranged in an arc shape. In the initial state, the cross-section of the annular airbag 4 is in a quasi-right trapezoid structure, and the textures of its first side 401, third side 403, and second side 402 become softer in sequence. The first side 401 is closer to the breast of the pregnant woman, and the second side 402 is relatively farther away from the breast of the pregnant woman. When compressed gas is filled into the annular airbag 4, the end of the third side 403 close to the first side 401 will move towards the breast of the pregnant woman first, and then the third side 403 will gradually move towards the breast of the pregnant woman along the direction away from the first side 401, causing the second side 402 to deform, so as to generate a gradually nipple-directed squeezing force on the breast of the pregnant woman, achieving a directional massage effect. This massage method can effectively stimulate the mammary gland, promote the generation and discharge of milk, help pregnant women increase the milk secretion volume, better meet the feeding needs of the baby. At the same time, the gradually squeezing force can dredge the mammary ducts, prevent milk stasis and mammary gland blockage, and reduce the risk of occurrence of mammary gland diseases such as mastitis. In addition, the massage can also promote the blood circulation of the breast, relieve the discomfort caused by milk stasis or breast distension, and improve the comfort of pregnant women.

[0031] The connecting ring 6 is arranged on the inner cover 1 and is communicated with the annular airbag 4. A plurality of groups of annular connecting pipelines 5 are coaxially arranged outside the inner cover 1, and the connecting pipelines 5 are equidistantly conducted with the annular airbag 4. Further, an outer cover 3 is also arranged outside the inner cover 1. By setting the outer cover 3, it can protect the inner cover 1 and the connecting pipelines 5, and avoid damage to the inner cover 1 or rupture of the connecting pipelines 5 due to dropping during use, resulting in abnormal use.

[0032] One end of the connecting pipeline 5 away from the annular airbag 4 is arranged on the communication ring 6 at equal circumferential intervals.

[0033] During use, multiple connecting pipelines 5 can be sequentially and staggeredly filled with compressed gas. Since the connecting pipelines 5 are connected to the corresponding annular airbags 4 at equal circumferential intervals, when the compressed gas enters the connecting pipelines 5, it will be evenly distributed to each area of the annular airbag 4. This design enables the annular airbag 4 to expand uniformly in a ring shape, fully conforming to the breast contour of the pregnant woman, thereby achieving all-round and uniform pressure massage on the breast within the range of the annular airbag 4.

[0034] This uniform expansion method can not only effectively avoid the phenomenon of local collapse during the expansion of the annular airbag 4, ensuring the stability and continuity of the massage process, but also guarantee the uniformity of the massage effect, enabling all parts of the breast to be fully stimulated. In this way, the directional massage function of the annular airbag 4 is further enhanced, providing a more accurate and effective breast care experience for the pregnant woman, promoting milk secretion, preventing breast problems, and improving the overall health level during lactation.

[0035] Please refer to Figures 9 to 10 , the switching member 7 is hermetically and rotationally connected to the communication ring 6. Two sets of connection positions are provided on the switching member 7. When the switching member 7 rotates, it can make two spaced annular airbags 4 communicate with the two sets of connection positions and block the annular airbag 4 in the middle; a pump pressure channel 701 and a pressure relief channel 702 are arranged in the switching member 7, and the pump pressure channel 701 and the pressure relief channel 702 form the two sets of connection positions; a first micro air pump 9 communicated with the pump pressure channel 701 is arranged on one side of the switching member 7, and the other side is connected to a micro motor 8 fixedly installed on the communication ring 6.

[0036] In this embodiment, a total of three annular airbags 4 are provided. These three annular airbags 4 are connected to the communication ring 6 through three connecting pipelines 5, and through holes are formed in the areas where the connecting pipelines 5 are connected to the communication ring 6. The three through holes are arranged at equal intervals and are evenly distributed within 180°. Further, both the pump pressure channel 701 and the pressure relief channel 702 are in a right-angled shape of 90°. One section is parallel to the central axis of the communication ring 6, and the other section is arranged along the radial direction of the communication ring 6. And the ends of the pump pressure channel 701 and the pressure relief channel 702 arranged along the radial direction of the communication ring 6 are arranged with opposite openings.

[0037] Based on the above arrangement, during use, when the pump pressure channel 701 is connected to the outermost (away from the nipple) annular airbag 4 through the connecting pipe 5, the annular airbag 4 can expand. After the annular airbag 4 expands to a predetermined degree, the switching element 7 can rotate under the drive of the micro motor 8, so that the switching element 7 can switch to connect the pump pressure channel 701 with the middle annular airbag 4. At the same time, the switching element 7 can block the outlet of the first group of annular airbags 4 in the expanded state, that is, while keeping the outermost annular airbag 4 expanded, the second group of annular airbags 4 is expanded. When the second group of annular airbags 4 expands to a predetermined degree, the switching element 7 will switch to pumping compressed gas toward the third group of annular airbags 4. At this time, the connecting pipe 5 connecting the outermost annular airbag 4 will be connected to the pressure relief channel 702. At this time, the outermost annular airbag 4 can be connected to the outside world to achieve a pressure relief effect.

[0038] It is not difficult to conclude from the above process that by rotating the switching member 7, the annular airbags 4 can be turned on one by one in sequence, so that a directional massage from the mammary gland to the nipple can be produced on the breast. By this massage method along the direction of the mammary duct towards the nipple, firstly, the flow of milk in the mammary duct can be effectively stimulated, and the mammary duct can be helped to remain unobstructed, thereby making it easier for the milk to be discharged. Secondly, by pushing from the periphery of the breast toward the nipple, the mammary tissue can be fully stimulated, the production and discharge of milk can be promoted, and the overall effect of lactation can be improved. At the same time, it can help push the milk to the nipple, making the milk discharge smoother, relieving breast pain and induration, and reducing the pain caused by milk swelling in pregnant women.

[0039] It should be noted that, in the present embodiment, when compressed gas is filled into the front group of annular airbags 4, the rear group of annular airbags 4 will still be in an expanded state, and this state can avoid blood reflux in the mammary gland during massage. This design can improve blood circulation in the breast, prevent mammary gland blockage and milk accumulation, and reduce the risk of breast diseases such as mastitis. At the same time, it can also relieve discomfort symptoms such as breast pain and improve the comfort of the parturient. The annular airbag 4 located in the rear group of annular airbags 4 away from the annular airbag 4 in the inflated state can be in a depressurized state, so that the annular airbag 4 can be separated from the skin of the breast, thereby avoiding the annular airbag 4 from being attached to the surface of the breast for a long time, causing discomfort such as breast sweating and stuffiness.

[0040] See also Figures 4 to 6 As an embodiment of the present invention, a wearable breast pump is also proposed, including the bionic sucking massage component for improving lactation, and also including: an adsorption plate 2, a negative pressure component and a blocking mechanism, and further including a restraining belt, which is detachably connected to the inner cover 1. When in use, the inner cover 1 can be covered on the breast through the restraining belt without the need to support it with hands, thereby freeing the hands of pregnant women.

[0041] The suction cup 2 is detachably mounted on the inner cover 1. An annular groove 201 is provided at the edge position of one end of the suction cup 2, and a suction port 203 is provided at the other end.

[0042] During use, the inner cover 1 covers the breast, and at the same time, the suction cup 2 is aligned with the nipple. At this time, when the negative pressure assembly operates, a negative pressure can be generated in the annular groove 201. Since the skin on the breast fits in the annular groove 201, in this state, the skin on the breast can be embedded into the annular groove 201, thereby achieving a better sealing effect between the breast and the suction cup 2. This design avoids the separation or generation of a gap between the suction cup 2 and the breast during milk extraction, resulting in the extracted milk slipping along the side wall of the breast and wetting the clothes, causing discomfort.

[0043] It should be noted that while aligning the suction cup 2 with the nipple, it is also necessary to ensure that the suction cup 2 covers the areola around the nipple. There are a relatively large number of Montgomery glands on the areola, and these glands will be more prominent during lactation. If the areola is just in the annular groove 201, first, the presence of the protrusion will affect the sealing between the breast and the annular groove 201, easily causing the milk to flow out. Second, when the Montgomery glands on the areola are recessed into the annular groove 201, the Montgomery glands will be deformed, and if they remain recessed in the annular groove 201 for a long time, the Montgomery glands may be damaged. Therefore, ensuring that the suction cup 2 correctly covers the areola can not only ensure the sealing effect but also protect the normal function of the Montgomery glands.

[0044] The negative pressure assembly is communicated with the annular groove 201. The negative pressure assembly can generate a negative pressure in the annular groove 201 when the breast of the pregnant woman fits onto the suction cup 2. The negative pressure assembly includes connecting channels 202 arranged at equal circumferential intervals in the suction cup 2, and one end of the connecting channel 202 extends into the annular groove 201; the negative pressure assembly further includes a connecting member 10 arranged at the end of the suction cup 2 and a negative pressure generating structure. An annular chamber is formed in the connecting member 10, and the annular chamber is communicated with the other end of the connecting channel 202. The negative pressure generating structure includes a second micro air pump 11 mounted on the connecting member 10 and communicated with the annular chamber. One end of the second micro air pump 11 communicated with the annular chamber is provided with a connecting pipe, and the connecting pipe is connected to the blocking mechanism.

[0045] When the second micro air pump 11 is started, it will evacuate the annular chamber in the connecting member 10. Since the annular chamber is in communication with the annular groove 201, when the breast skin fits on the annular groove 201, the evacuation process will generate a negative pressure in the annular space formed between the annular groove 201 and the breast skin, thereby causing the breast skin to sink into the annular groove 201 and ensuring the sealing between the breast and the suction cup 2.

[0046] It should be noted that the annular chamber is connected to the annular groove 201 through multiple groups of connecting channels 202 that are equidistantly distributed in a circular pattern. This design ensures that when the breast skin fits within the annular groove 201, the negative pressure within the connecting channels 202 can uniformly generate negative pressure within the annular groove 201, enabling the skin covering the annular groove 201 to uniformly fit to its inner side, further enhancing the sealing effect and avoiding the problem that other areas of the annular groove 201 cannot fit with the breast skin after a single connecting channel 202 is blocked by the skin.

[0047] In addition, a pressure sensor is provided within the second micro air pump 11. When the skin fits within the annular groove 201, the annular groove 201 and the annular chamber form a connected chamber. The pressure sensor can detect the air pressure within the annular chamber. Once the air pressure reaches a preset value, it can be determined that the air pressure within the annular groove 201 has also reached the preset value. At this time, the system will promptly control the second micro air pump 11 to stop evacuating the air, avoiding the pain caused to the skin that has sunk into the annular groove 201 due to excessive evacuation of the air.

[0048] Please refer to Figures 6 to 7 , the plugging mechanism is connected to the negative pressure assembly, and the plugging mechanism can plug the suction port 203 when the negative pressure intensity within the negative pressure assembly decreases; the plugging mechanism includes a retention cylinder body 12 installed on the adsorption disc 2. One end of the retention cylinder body 12 is connected to the connecting pipe, and a sealing plug 13 is hermetically and slidably installed within the retention cylinder body 12. The sealing plug 13 is connected to the other end of the retention cylinder body 12 through a cylindrical spring 14; the plugging mechanism further includes a follow-up assembly for changing the conduction state of the suction port 203. The follow-up assembly includes a connecting frame 15 that is slidably arranged through the retention cylinder body 12. One end of the connecting frame 15 is connected to the sealing plug 13, and the other end is provided with a plugging member 16, and the plugging member 16 can fit to the suction port 203.

[0049] In this embodiment, when the skin of the breast fits into the annular groove 201, the annular groove 201, the connecting channel 202, the annular chamber, the connecting tube and the hysteresis cylinder 12 are located on one side of the sealing plug 13 to form a closed chamber. When the second micro air pump 11 is evacuated and the breast skin sinks into the annular groove 201, the hysteresis cylinder 12 is located on one side of the sealing plug 13 and negative pressure is generated synchronously. At this time, the sealing plug 13 can move away from the cylindrical spring 14 under the action of the negative pressure, so that the cylindrical spring 14, which is already in a stretched state in the initial state, is further stretched. At the same time, the sealing plug 13 drives the blocking member 16 to move away from the suction port 203 through the connecting frame 15, so that the suction port 203 can be opened. In this state, the external extraction device connected to the suction port 203 can generate negative pressure in the adsorption disk 2, thereby extracting the milk in the breast from the nipple position.

[0050] Based on the above arrangement, the suction port 203 can be opened only when a sealing state is formed between the breast skin and the annular groove 201, and the milk suction action can be performed under the suction of the external extraction device, thereby avoiding milk suction when the fit between the breast skin and the suction plate 2 is not high and the sealing is insufficient, resulting in the sucked lotion sliding along the breast skin to the outside of the suction plate 2, causing waste and wetting clothes to cause discomfort to pregnant women.

[0051] It should also be noted that when the suction plate 2 is attached to the nipple, the milk can be extracted under the suction of the external extraction device even if the sealing between the two is poor. However, due to the poor sealing, pressure release is likely to occur, resulting in insufficient milk suction intensity and inability to completely discharge the milk. Secondly, the external extraction device adopts an intermittent extraction method to imitate the action of a baby sucking milk. At the same time, the negative pressure generated during suction can produce a certain sealing effect between the breast skin and the suction plate 2. However, when the external extraction device stops, this negative pressure state will disappear, which will cause insufficient sealing between the breast skin and the suction plate 2, thereby causing the milk to slide along the breast skin.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
