Description

Technical Field

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

[0002] Lactation massage is a method of promoting milk secretion through physical stimulation. It cleverly combines the theory of meridians in traditional Chinese medicine with modern physiological principles. During the operation, professional masseurs use skilled techniques to stimulate the breasts and surrounding acupuncture points. This process can effectively promote blood circulation and lymphatic return, thereby dredging the mammary ducts, enhancing the activity of mammary cells, and ultimately achieving the purpose of increasing the amount and quality of milk secretion.

[0003] The massage technique for inducing lactation is quite particular. Usually, massage is performed from the outside of the breast towards the nipple. This direction design is in line with the physiological structure of the breast and can better promote the flow of milk towards the nipple.

[0004] With the development of science and technology, in order to realize the automation of lactation, existing breast pumps are equipped with massage components to enable massage while sucking milk. This design aims to improve the convenience and efficiency of lactation. Specifically, the air bag installed inside the breast pump will produce a certain degree of pressure on the breast when cooperating with the milk 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 is that the breast pressure lacks accurate direction. The ideal massage direction should be from the outside of the breast to the nipple, but the air bag pressing method often cannot accurately achieve this direction, resulting in blood and lymph flow disorder. This disorder not only affects the comfort of the massage, but more importantly, it greatly reduces the lactation effect. Summary of the invention

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.

[0021] See also Figure 1 to Figure 10In an embodiment of the present invention, a bionic sucking massage component for improving lactation includes: an inner cover 1, a connecting ring 6 and a switching member 7, so that the annular airbags 4 can be turned on one by one by the rotation of the switching member 7, so that a directional massage from the mammary gland to the nipple can be produced on the breast. By massaging the nipple along the direction of the mammary duct, firstly, the flow of milk in the mammary duct can be effectively stimulated, and the mammary duct can be helped to keep it unobstructed, so that the milk can be discharged more easily. 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 improvement of the quality of the breast can be improved. The overall effect of high lactation induction can also help push milk to the nipple, making milk discharge smoother, relieving breast pain and induration, and reducing the pain caused by breast swelling in pregnant women. Specifically, a plurality of groups of annular airbags 4 with successively changing radii are equidistantly arranged in the inner cover 1, and 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, the third side 403 and the inner wall of the inner cover 1 form a closed chamber; the third side 403 is directed toward the inner cover 1 in a direction away from the first side 401. The inner wall of the annular airbag 4 is offset, so that the third side 403 is inclined relative to the inner cover 1, and the second side 402 is set in an arc shape. In the initial state, the cross section of the annular airbag 4 is a right-angled trapezoidal structure, and the textures of the first side 401, the third side 403 and the 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 far 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 preferentially move toward the breast of the pregnant woman, and then the third side 403 moves away from the first side 401. The second side edge 402 is deformed, thereby exerting a squeezing force gradually toward the nipple of the pregnant woman's breast, thereby achieving a directional massage effect. This massage method can effectively stimulate the mammary gland, promote the production and discharge of milk, help pregnant women increase milk secretion, and better meet the feeding needs of the baby. At the same time, the gradual squeezing force can dredge the mammary duct, prevent milk stasis and mammary gland blockage, and reduce the risk of mastitis and other breast diseases. In addition, massage can also promote blood circulation in the breast, relieve the discomfort caused by milk stasis or breast pain, and improve the comfort of pregnant women.

[0022] The connecting ring 6 is arranged on the inner cover 1 and is connected with the annular airbag 4. A plurality of groups of annular connecting pipes 5 are coaxially arranged on the outside of the inner cover 1. The connecting pipes 5 are equidistantly connected with the annular airbag 4. Furthermore, an outer cover 3 is also arranged on the outside of the inner cover 1. The outer cover 3 can protect the inner cover 1 and the connecting pipes 5 to avoid damage to the inner cover 1 or rupture of the connecting pipes 5 due to falling during use, which may result in failure to use the device normally.

[0023] One end of the connecting pipeline 5 away from the annular airbag 4 is arranged on the connecting ring 6 at equal distances from the circumference.

[0024] During use, multiple connecting pipes 5 can be filled with compressed gas in sequence and staggeredly. Since the connecting pipes 5 are connected to the corresponding annular airbags 4 at equal intervals in a circle, when the compressed gas enters the connecting pipes 5, it will be evenly distributed to each area of ​​the annular airbag 4. This design allows the annular airbag 4 to expand evenly in a ring shape and fully fit the breast contour of the pregnant woman, thereby achieving all-round and uniform pressure massage of the breast within the range of the annular airbag 4.

[0025] This uniform expansion method can not only effectively avoid local collapse during the expansion of the annular airbag 4, ensuring the stability and continuity of the massage process, but also ensure the uniformity of the massage effect, so that all parts of the breast can be fully stimulated. In this way, the directional massage function of the annular airbag 4 can be further enhanced, providing pregnant women with a more accurate and effective breast care experience, promoting milk secretion, preventing breast problems, and improving the overall health level of lactation.

[0026] See also Figure 9~Figure 10 The switching member 7 is sealed and rotatably connected with the connecting ring 6. Two groups of connection positions are arranged on the switching member 7. When the switching member 7 rotates, the two groups of the annular airbags 4 separated by a gap can be connected with the two groups of the connection positions, and the annular airbag 4 located in the middle is blocked; 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 two groups of the connection positions; a first micro air pump 9 connected with the pump pressure channel 701 is arranged on one side of the switching member 7, and the other side is connected with a micro motor 8 fixedly mounted on the connecting ring 6.

[0027] In this embodiment, three groups of annular airbags 4 are provided, and the three groups of annular airbags 4 are connected to the connecting ring 6 through three groups of connecting pipes 5, and the area where the connecting pipes 5 are connected to the connecting ring 6 is formed with three groups of equidistant through holes, and the three groups of through holes are evenly distributed within 180°. Furthermore, the pump pressure channel 701 and the pressure relief channel 702 are both in a 90° right angle shape, one section of which is parallel to the central axis of the connecting ring 6, and the other section is arranged along the radial direction of the connecting ring 6, and the ends of the pump pressure channel 701 and the pressure relief channel 702 arranged along the radial direction of the connecting ring 6 are opened in reverse.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] See also Figure 4~Figure 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.

[0032] The adsorption disk 2 is detachably mounted on the inner cover 1 , an annular groove 201 is provided at the edge of one end of the adsorption disk 2 , and a suction port 203 is provided at the other end.

[0033] When in use, the inner cover 1 covers the breast, and the suction plate 2 is aimed at the nipple. At this time, when the negative pressure component is activated, 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 in the annular groove 201, thereby achieving a better sealing effect between the breast and the suction plate 2. This design avoids the separation of the suction plate 2 and the breast or the generation of a gap during the milk suction process, causing the extracted milk to slide along the side wall of the breast, wetting the clothes and causing discomfort.

[0034] It is worth noting that when the suction plate 2 is aligned with the nipple, it is also necessary to ensure that the suction plate 2 covers the areola around the nipple. There are a large number of Montgomery glands on the areola, and these glands will be more prominent during lactation. If the areola happens to be in the annular groove 201, firstly, the presence of the protrusion will affect the sealing between the breast and the annular groove 201, which will easily cause milk to flow out. Secondly, 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 also be damaged. Therefore, ensuring that the suction plate 2 correctly covers the areola can not only ensure the sealing effect, but also protect the normal function of the Montgomery glands.

[0035] The negative pressure component is connected to the annular groove 201. When the pregnant woman's breast is attached to the adsorption plate 2, the negative pressure component can generate negative pressure in the annular groove 201. The negative pressure component includes connecting channels 202 equidistantly arranged in a circle in the adsorption plate 2, and one end of the connecting channel 202 extends into the annular groove 201; the negative pressure component also includes a connecting piece 10 and a negative pressure generating structure arranged at the end of the adsorption plate 2, an annular chamber is formed in the connecting piece 10, and the annular chamber is connected to the other end of the connecting channel 202. The negative pressure generating structure includes a second micro air pump 11 installed on the connecting piece 10 and connected to the annular chamber, and a connecting pipe is provided at one end of the second micro air pump 11 connected to the annular chamber, and the connecting pipe is connected to the blocking mechanism.

[0036] When the second micro air pump 11 is started, it will perform a vacuum operation on the annular chamber in the connecting piece 10. Since the annular chamber is connected to the annular groove 201, when the breast skin is attached to the annular groove 201, the vacuum process will cause the annular space formed between the annular groove 201 and the breast skin to generate negative pressure, thereby causing the breast skin to sink into the annular groove 201, ensuring the sealing between the breast and the suction plate 2.

[0037] It is worth noting that the annular chamber is connected to the annular groove 201 through multiple groups of connecting channels 202 that are equidistantly distributed around the circumference. This design ensures that when the breast skin fits into the annular groove 201, the negative pressure in the connecting channel 202 can cause a uniform negative pressure to be generated in the annular groove 201, which enables the skin covering the annular groove 201 to fit evenly to its inner side, further improving the sealing effect and avoiding the problem that other areas of the annular groove 201 cannot fit into the breast skin due to the use of a single connecting channel 202 and the skin blocking the connecting channel 202.

[0038] In addition, an air pressure sensor is provided in the second micro air pump 11. When the skin fits in the annular groove 201, the annular groove 201 and the annular chamber form a connected chamber, and the air pressure sensor can detect the air pressure in the annular chamber. Once the air pressure reaches a preset value, it can be determined that the preset value has also been reached in the annular groove 201. At this time, the system will promptly control the second micro air pump 11 to stop vacuuming, so as to avoid pain to the skin trapped in the annular groove 201 due to excessive vacuuming.

[0039] See also Figure 6~Figure 7 The blocking mechanism is connected to the negative pressure component, and the blocking mechanism can block the suction port 203 when the negative pressure intensity in the negative pressure component decreases; the blocking mechanism includes a hysteresis cylinder 12 installed on the adsorption disk 2, one end of the hysteresis cylinder 12 is connected to the connecting pipe, and a sealing plug 13 is sealingly and slidably installed in the hysteresis cylinder 12, and the sealing plug 13 is connected to the other end of the hysteresis cylinder 12 through a cylindrical spring 14; the blocking mechanism also includes a follower component for changing the conduction state of the suction port 203, and the follower component includes a connecting frame 15 slidably arranged through the hysteresis cylinder 12, one end of the connecting frame 15 is connected to the sealing plug 13, and the other end is provided with a blocking piece 16, and the blocking piece 16 can be fitted to the suction port 203.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.
