Description

Technical Field

[0001] The present application relates to the technical field of breast milk collection, and in particular to a breast milk collector for gynecological care. Background Art

[0002] Breast milk is the most natural, safest, and most complete food for infants. It contains all the nutrients and antibodies a baby needs to thrive. Even when mother and baby are separated for special reasons, breastfeeding is still necessary. Proper breastfeeding is gaining increasing attention and is crucial for improving nutrition and preventing cross-infection. However, proper collection of breast milk is particularly important, as it can be easily contaminated, leading to spoilage and quality issues.

[0003] Using a breast milk collector can reliably collect excess milk, such as a multifunctional breast milk collector with publication number CN212282355U, which includes a milk collecting bottle and a tight pressure connection structure connected to the milk collecting bottle and a functional component. The top of the milk collecting bottle is detachably connected to at least one functional head through the tight pressure connection structure. The tight pressure connection structure includes an inner screw sleeve, an outer screw sleeve and an extension connector on the top of the milk collecting bottle and a sealing head provided on each functional head. The outer sleeve of the extension connector is connected to the outer sleeve and locked with each other. The sealing head of the functional head is detachably connected to the inner screw sleeve. The inner screw sleeve and the outer screw sleeve are threadedly connected to each other so that the end plane of the extension connector and the end plane of the sealing head are sealed and fit together, and the functional head and the milk collecting bottle are tightly pressure-locked. The threaded connection between the inner screw sleeve and the outer screw sleeve adopts an interference thread connection; the functional head tightly pressure-connected to the top of the milk collecting bottle is a milk suction cup, and the bottom of the milk collecting bottle is provided with a suction cup.

[0004] However, the above-mentioned prior art still has some defects when it comes to collecting breast milk: 1. The above-mentioned prior art ensures a sealed connection between the breast shield and the milk collection bottle through a tight pressure connection structure, and utilizes the sealing performance of the tight pressure structure to completely prevent the entry of external air, thereby making the breast shield have a strong adsorption force and adsorption bearing capacity. However, during use, due to the different breast sizes between people, the adsorption force of the breast shield may be weakened.

[0005] 2. In the above-mentioned prior art, the index finger and thumb are simultaneously pressed against the concave portions on the left and right walls of the milk collecting bottle to separate them by vacuum negative pressure, so that the breast cup is adsorbed on the breast. However, this method of collecting breast milk cannot control the suction force when the breastfeeding mother is sucking milk. The suction force may be too low to suck out the breast milk, or too high to cause discomfort to the breastfeeding mother.

[0006] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for collecting breast milk. Summary of the Invention

In order to collect breast milk, the collection device 3 is further provided at the lower end of the extraction cover 11. The collection device 3 includes a collection hole 31 opened at the lower end of the extraction cover 11. The collection device 3 is further provided at the lower end of the extraction cover 11, and the collection hole 31 is located in the center of the connecting ring 32 to collect the breast milk sucked from the inside of the extraction cover 11. A rotating ring 33 is rotatably installed on the outer side of the connecting ring 32. A mounting groove 34 is opened inside the rotating ring 33. A mounting ring 35 is rotatably installed on the mounting groove 34. A plurality of limiting sliding holes 36 are evenly circumferentially opened on the side end of the connecting ring 32. A sliding stopper 37 is slidably connected to the limiting sliding hole 36, and the sliding stopper 37 is tilted upward at one end facing the center of the connecting ring 32. The sliding stopper 37 is connected to the mounting ring 35 by a return spring 38. The rotational connection between the ring 33 and the mounting ring 35 enables the return spring 38 to normally pop out the sliding block 37 when the rotating ring 33 rotates. An arc groove 39 is provided at the upper end of the mounting groove 34, and a limiting slide post 310 is provided at the upper end of the sliding block 37, and the limiting slide post 310 slides in the arc groove 39. The sliding setting of the limiting slide post 310 in the arc groove 39 enables the sliding block 37 to slide in the limiting slide hole 36 when the rotating ring 33 is rotated. A collecting bottle 311 is also installed at the lower end of the extraction cover 11, and the bottle mouth of the collecting bottle 311 is sleeved in the connecting ring 32 for collecting breast milk.

[0043] Before extracting breast milk, the collecting bottle 311 is pushed upward at the lower end of the connecting ring 32 until the retaining ring 312 on the collecting bottle 311 passes over the sliding block 37 and is stuck, so that the collecting bottle 311 is stuck in the connecting ring 32, and then the breast milk collection is started. When the collection is completed, the rotating ring 33 is rotated, and then the sliding block 37 slides in the limiting sliding hole 36 with the cooperation of the limiting sliding column 310 and the arc groove 39, releasing the restriction of the sliding block 37 on the retaining ring 312, so that the collecting bottle 311 filled with breast milk can be taken out for storage.

[0044] refer to Figure 6, is a structural diagram of the suction device 4 of the present invention. In order to suck breast milk into the collection bottle 311, the suction device 4 is provided in the installation box 12. The suction device 4 includes a mounting plug 41 provided at the collection hole 31. The lower end of the mounting plug 41 is provided with a liquid level detection head 42 to detect the liquid level of the breast milk in the collection bottle 311. A negative pressure suction machine 43 is installed inside the installation box 12 to provide a power source for sucking breast milk. When the liquid level exceeds the liquid level detection head 42, the negative pressure suction machine 43 stops working. The suction end and the exhaust end of the negative pressure suction machine 43 are distributed and connected The suction pipe 44 and the exhaust pipe 45 are provided. The suction pipe 44 passes through the mounting plug 41 in the collecting bottle 311, and the lower end of the suction pipe 44 is higher than the liquid level detection head 42 to prevent breast milk from entering the suction pipe 44. The exhaust pipe 45 discharges the gas in the collecting bottle 311, so that negative pressure is generated in the collecting bottle 311. A milk suction pipe 46 is also installed through the mounting plug 41. The negative pressure in the collecting bottle 311 causes breast milk to flow from the milk suction pipe 46 into the collecting bottle 311. An adjustment knob 48 for adjusting the suction force of the negative pressure suction machine 43 is installed on the outer wall of the mounting box 12 through the control panel 47.

[0045] When collecting breast milk, the suction force of the negative pressure suction machine 43 is adjusted by adjusting the knob 48. The negative pressure suction machine 43 creates a negative pressure in the collection bottle 311, and the breast milk enters the collection bottle 311 from the milk suction tube 46, completing the collection of the breast milk. At the same time, the liquid level detection head 42 prevents the breast milk in the collection bottle 311 from being sucked into the suction tube 44.

[0046] refer to Figure 7 , which is a structural schematic diagram of the storage device 5 of the present invention. In order to lead out the milk suction tube 46 and the exhaust tube 45 to facilitate the extraction of breast milk, and to prevent the milk suction tube 46 and the exhaust tube 45 from being too long and inconvenient to store when the device is not in use, a storage device 5 is provided at the upper end of the extraction cover 11. The storage device 5 includes a storage cavity 51 provided at the upper end of the extraction cover 11. The storage cavity 51 is connected to the interior of the installation box 12 through a communicating hole 52. A connecting hose 53 is installed on the communicating hole 52, and the milk suction tube 46 and the exhaust tube 45 are both arranged in the connecting hose 53 to protect the milk suction tube 46 and the exhaust tube 45. A storage column 54 is rotatably installed on the upper end of the extraction cover 11. The storage column 54 passes through the middle of the storage cavity 51 to the top of the extraction cover 11, and the connecting hose 53 is wrapped around the storage column 54. The connecting hose 53 passes through the connecting hole 13, and a rotating disk 55 is installed on the upper end of the storage column 54.

[0047] When the connecting hose 53 is stored in the storage cavity 51, the rotating disk 55 is rotated to rotate the storage column 54, thereby winding the connecting hose 53 around the storage column 54. Similarly, when sucking breast milk, the rotating disk 55 needs to be rotated in the opposite direction to loosen the connecting hose 53 wound around the storage column 54, so as to extend the connecting hose 53 and facilitate sucking breast milk.

[0048] refer to Figure 8, is a structural schematic diagram of the mounting element 56 of the present invention. When the connecting hose 53 is stored in the storage cavity 51, one end of the connecting hose 53 needs to be fixed. The storage device 5 also includes a mounting element 56 provided on the side wall of the extraction cover 11. The mounting element 56 includes a mounting bracket 561 provided on the side wall of the extraction cover 11, and the mounting bracket 561 is located below the connecting hole 13. A mounting block 562 is provided on the end of the mounting bracket 561 facing away from the extraction cover 11, and a gripping handle 563 is provided on the end of the connecting hose 53 facing away from the extraction cover 11. The gripping handle 563 is the part that the breast suction tube 46 holds when sucking breast milk, and the gripping handle 563 cooperates with the mounting block 562. After the connecting hose 53 is stored in the storage cavity 51, the gripping handle 563 is placed on the mounting block 562 to complete the storage of the connecting hose 53.

[0049] refer to Figure 9 , is a structural schematic diagram of the breast pumping device 6 of the present invention. When sucking breast milk, in order to facilitate operation and more reliably collect breast milk, the breast pumping device 6 is connected to the gripping handle 563. The breast pumping device 6 includes a rotating cylinder 61 rotatably mounted on the end of the gripping handle 563 away from the extraction cover 11, and a breast shield 62 is rotatably mounted on the rotating cylinder 61. A pressure dividing ring 63 is provided on the edge of the breast shield 62 to distribute the pressure of the breast shield 62 on the chest, thereby improving the comfort when collecting breast milk. The exhaust pipe 45 is connected to the mounting tube 64, and the mounting tube 64 passes through the breast shield 62 from the inside to the outside. The breast milk tube 46 is connected to the breast pump box 65 for buffering breast milk to prevent the breast milk from leaking out due to excessive collection speed. A breast pumping hole 66 is opened on the side wall of the breast pump box 65 away from the breast milk tube 46.

[0050] When collecting breast milk, the user needs to hold the handle 563, cover the breast shield 62 on the chest, and insert the nipple into the breast suction hole 66. The breast suction tube 46 will create negative pressure in the breast shield 62, thereby drawing the breast milk into the breast suction box 65 and collecting it through the breast suction tube 46.

[0051] refer to Figure 10, is a structural diagram of the adjustment device 7 of the present invention. When collecting breast milk, the chest needs to be supported to ensure that the nipple is always facing the milk suction hole 66. An adjustment device 7 is also provided inside the breast shield 62. The adjustment device 7 includes an adjustment frame 71 symmetrically installed on the inner wall of the breast shield 62. The two ends of the adjustment frame 71 are connected by a connecting block 72, and the mounting tube 64 passes through the connecting block 72 installed at the upper end of the adjustment frame 71 to prevent the breast shield 62 from rotating when the rotating cylinder 61 rotates. A blocking plate 73 is installed on the two connecting blocks 72. When in use, To prevent the breast from contacting the barrier plate 73 facing the elements of the connecting hose 53, in order to protect the breast, an adjustment hole 74 is provided on the adjustment frame 71, and an adjustment slider 75 is symmetrically slidably set in the adjustment hole 74. The adjustment sliders 75 of the same height are connected by a connecting strip 76, and a mounting strip 77 is installed on the connecting strip 76. The distance between the mounting strips 77 can be adjusted, and a breast support plate 78 is detachably installed on the mounting strip 77 to facilitate cleaning of the breast support plate 78 to prevent cross infection. The breast support plates 78 jointly support the breasts to further improve the comfort when collecting breast milk.

[0052] When collecting breast milk, the distance between the mounting bars 77 is adjusted to accommodate different breast sizes, and the breast support plates 78 are used to support the breasts to prevent the breasts from shifting during breast milk collection, which would cause the breast milk to flow out of the breast pump box 65. The breast support plates 78 are detachable, making it easy to clean any contact with them.

[0053] refer to Figure 11 , is a structural diagram of the transmission device 8 of the present invention. In order to freely adjust the distance between the chest support plates 78 to adapt to different chest sizes, the transmission device 8 is installed on the adjustment frame 71. The transmission device 8 includes two rotating columns 81 respectively rotatably installed on the two adjustment frames 71. The rotating columns 81 pass through the lower ends of the adjustment frames 71, and the rotating columns 81 are provided with threads with opposite spiral directions. The adjusting sliders 75 in the same adjustment hole 74 are respectively symmetrically threadedly connected to the corresponding rotating columns 81, so that when the rotating columns 81 rotate, the adjusting sliders 75 on the same rotating column 81 move toward or relative to each other. The first gear 82 is moved, thereby changing the distance between the breast support plates 78. The lower end of the rotating column 81 is installed with a first gear 82, and the connecting block 72 at the lower end of the adjusting frame 71 is rotatably installed with a gear shaft 83. The lower end of the gear shaft 83 is installed with a second gear 84 that meshes with the first gear 82. The rotation of the second gear 84 drives the first gear 82 to rotate. The upper end of the gear shaft 83 is provided with a third gear 85. The end of the rotating cylinder 61 located inside the breast shield 62 is provided with a transmission ring gear 86, and the transmission ring gear 86 is meshed with the third gear 85. The rotation of the transmission ring gear 86 drives the third gear 85 to rotate.

[0054] When adjusting the distance between the breast support plates 78, the rotating cylinder 61 is rotated, and the gear shaft 83 is rotated under the engagement of the transmission ring gear 86 and the third gear 85, thereby driving the second gear 84 and the first gear 82 engaged with the second gear 84 to rotate, and finally the rotating column 81 is rotated. Under the threaded cooperation between the rotating column 81 and the adjusting slider 75, the adjusting sliders 75 are moved closer to or away from each other, thereby adjusting the distance between the breast support plates 78.

[0055] refer to Figure 12 , which is a structural schematic diagram of the pressure relief device 9 of the present invention. After the collection of breast milk is completed, it is necessary to let external air into the breast shield 62 to make the external air pressure and the air pressure inside the breast shield 62 consistent so that the breast shield 62 can be removed. A pressure relief device 9 is provided at the bottom end of the breast shield 62. The pressure relief device 9 includes a pressure relief hole 91 opened at the bottom end of the breast shield 62. A pressure relief column 92 is slidably connected to the pressure relief hole 91. The pressure relief column 92 controls the flow of air inside and outside the breast shield 62. A pressure relief lifting plate 93 and a connecting plate 94 are respectively provided at both ends of the pressure relief column 92, and the pressure relief lifting plate 93 is located on the outside of the breast shield 62, and the connecting plate 94 is located on the inside of the breast shield 62. The connecting plate 94 is connected to the inside of the breast shield 62 by a connecting spring 95, so that the pressure relief hole 91 remains closed. Pressure relief grooves 96 are also uniformly opened circumferentially on the side wall of the pressure relief column 92 to facilitate air exchange.

[0056] Before removing the breast shield 62, the air pressure inside the breast shield 62 is lower than the outside air pressure, making it difficult to remove. At this time, the pressure relief column 92 is pulled out by the pressure relief lifting plate 93, and the air outside the breast shield 62 enters the breast shield 62 through the pressure relief groove 96, so that the outside air pressure and the air pressure inside the breast shield 62 are consistent, making it easier to remove the breast shield 62. After the pressure relief lifting plate 93 is released, the pressure relief column 92 is reset under the action of the connecting spring 95.

[0057] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
