[0032] A shifting mechanism 8 is provided between the connecting plate 5 and the two protective components 1 to improve the performance of the tight-fitting component 6;

[0033] The shifting mechanism 8 includes a gear ring 81 fixedly connected to one end of a plurality of carrier plates 61 away from the collar 62. The gear ring 81 is rotatably connected to the fixed ring 11 on the side near the outer disk 15 and is located between the outer cover 13 and the inner cover 12.

The axles of the two second pulleys 84 are fixedly connected to the axles of the two first gears 82 respectively. The axle of the first pulley 83 is rotatably connected to the connecting plate 5 and is located between the two second pulleys 84. A micro motor 85 is provided below the first pulley 83 and is fixedly installed on one side of the connecting plate 5. An incomplete gear 86 is fixedly connected to one end of the output shaft of the micro motor 85. A second gear 87 that meshes with the incomplete gear 86 is fixedly connected to the end of the axle of the first pulley 83 away from the connecting plate 5.

[0034] A guide rod 88 is fixedly connected to the side of the connecting plate 5 opposite to the gas tank 67 via an extension plate. The cross-sectional shape of the guide rod 88 is square. A toothed plate 89 is movably sleeved on the outside of the guide rod 88. A third gear 90 that meshes with an incomplete gear 86 is rotatably connected to the side of the connecting plate 5 opposite to the gas tank 67. The third gear 90 is located directly below the incomplete gear 86. A torsion spring 91 is fixedly connected between the third gear 90 and the connecting plate 5. The torsion spring 91 is movably sleeved on the outside of the axle of the third gear 90. A T-shaped block 92 is slidably connected to the top end of the T-shaped rod 69 near the side of the connecting plate 5. A slot for cooperating with the T-shaped block 92 is provided inside the T-shaped rod 69. A second spring 93 is fixedly connected to the side of the T-shaped block 92 away from the connecting plate 5. The end of the second spring 93 away from the T-shaped block 92 is fixedly connected to the inside of the slot. A top block 94 that cooperates with the T-shaped block 92 is fixedly connected to the top end of the toothed plate 89.

[0035] Both the inner cover 12 and the outer cover 13 are composed of multiple arc-shaped round rods, and the fixing plate is composed of a disc and a cylinder set at the end of the disc away from the fixing ring 11;

[0036] The protective plate 66 has a side cross-sectional shape of U-shape and consists of a plate with an L-shaped side cross-section and two square rods disposed between the L-shaped plate and the connecting plate 5.

[0037] Before using this breast care device, you can first wrap the wound on the breast with gauze. When wearing it, simply put the two protective components 1 over the two breasts respectively, then wrap the two elastic bands 3 from under the armpits to the back, and use Velcro 4 to fix the two elastic bands 3 together to complete the wearing of the care device.

[0038] In use, the micro motor 85 can be turned on, driving the incomplete gear 86 to rotate clockwise. When the incomplete gear 86 rotates to the position where it meshes with the third gear 90, the incomplete gear 86, through meshing with the third gear 90, drives the third gear 90 to rotate counterclockwise, and the torsion spring 91 stores force. Simultaneously, as the third gear 90 rotates, through meshing with the toothed plate 89, it causes the toothed plate 89 to move upwards outside the guide rod 88, so that the toothed plate 89 drives the top block 94 to move upwards synchronously. During the upward movement, the top block 94 interacts with the T-block 92. The resistance between them causes the T-shaped block 92 to drive the T-shaped rod 69 to move upward synchronously, which in turn causes the T-shaped rod 69 to drive the piston 68 to move upward synchronously inside the air tank 67 and squeeze the first spring 73. This causes the piston 68 to move upward and squeeze the air out of the air tank 67. At this time, the valve body 72 inside the air inlet pipe 71 is closed, and the air in the air tank 67 is squeezed into the synchronization pipe 64 through the two inflation pipes 70, and then enters the multiple airbags 63 through the synchronization pipe 64 and multiple bends 65. This causes the multiple airbags 63 to inflate, adhere to the breast and apply pressure, so that the skin flap adheres tightly to the chest wall and prevents the accumulation of fluid and air.

[0039] When the incomplete gear 86 rotates to the position where it meshes with the second gear 87, the incomplete gear 86 drives the second gear 87 to rotate counterclockwise through the meshing action between the incomplete gear 86 and the second gear 87. The second gear 87 drives the first pulley 83 and the two second pulleys 84 to rotate counterclockwise synchronously. This causes the two second pulleys 84 to drive the two first gears 82 to rotate. The two first gears 82 then drive the toothed ring 81 to rotate at a certain angle through the meshing action between the two first gears 82 and the toothed ring 81. This causes the toothed ring 81 to drive the multiple carrier plates 61 and the collar 62 to rotate synchronously. This allows the multiple carrier plates 61 to drive the airbags 63 to rotate synchronously, thereby changing the position of the multiple airbags 63. This ensures that the multiple airbags 63 maintain the patient's chest ventilation while ensuring the pressure effect of the multiple airbags 63 on the wound at the breast.

[0040] When the incomplete gear 86 rotates to the position where it meshes with the second gear 87, the incomplete gear 86 disengages from the third gear 90. At this time, the third gear 90 rotates in the opposite direction under the release and reset action of the torsion spring 91, and drives the toothed plate 89 to move downward outside the guide rod 88 through its meshing action with the toothed plate 89. This causes the toothed plate 89 to drive the top block 94 to move downward synchronously, thereby releasing the contact action of the top block 94 with the T-shaped block 92. At this time, the piston 68, under the extension and reset action of the first spring 73, drives the T-shaped rod 69 to move downward and reset, causing the T-shaped rod 69 to drive the T-shaped block 92 to move downward and reset synchronously. At this time, the valve body 72 in the intake pipe 71 is closed, and the piston... As the airbag 63 moves downward in the air tank 67, the air in the airbag 63 is drawn back into the air tank 67 through the bend 65, the synchronization tube 64, and the inflation tube 70, causing the multiple airbags 63 to contract and release the tight contact and pressure between the airbags and the breast. This allows the multiple airbags 63 to retract between the inner cover 12 and the outer cover 13. This facilitates the switching of the positions of the multiple airbags 63 through the meshing of the incomplete gear 86 and the second gear 87 and the cooperation between the various structures. This avoids the multiple airbags 63 continuously applying pressure to the same position, which could affect blood flow and air circulation at the wound site. It also prevents the airbags 63 from rubbing against the wound during the switching process, which could affect the patient's experience.

[0041] Before using the device, the valve 72 in the air inlet pipe 71 can be opened according to the usage requirements. Air, cold water or hot water can be added into the air tank 67 through the air inlet pipe 71. During use, the air can be used to inflate the airbag 63 by the cooperation of the above structures to achieve the effect of pressurizing the wound. Hot water or cold water can also be filled into the airbag 63 by the cooperation of the above structures to achieve the effect of hot or cold compress on the chest, thereby improving the applicability and scope of use of the device.

[0042] This invention, by incorporating a protective component 1 and designing the inner cover 12 and outer cover 13 as hollow structures, not only protects the chest after surgery, preventing external impacts or compression, but also ensures the breathability of the postoperative wound, which is beneficial for wound recovery. Furthermore, by including a close-fitting component 6 and a repositioning mechanism 8, the invention ensures wound breathability while allowing the airbag 63 to conform to the patient's chest and apply pressure, keeping the skin flap tightly against the chest wall to prevent fluid and air accumulation. It also allows for switching the position of the airbag 63, preventing it from continuously applying pressure to a single location on the chest, which could impede blood flow and air circulation at the wound site, thus further promoting postoperative wound recovery and improving the overall effectiveness of the device.

[0043] like Figures 1 to 8 As shown, the connecting plate 5 is provided with an adjustment mechanism 10 on the side opposite to the gas tank 67, which can improve the user experience of the tight-fitting component 6.

[0044] The adjustment mechanism 10 includes a square frame 101 fixedly connected to the side opposite to the connecting plate 5 and the gas tank 67, and the square frame 101 is located on one side of the top block 94. The inside of the square frame 101 is rotatably connected to a threaded rod 102 with a knob on the top. The outside of the threaded rod 102 is threaded with an abutment block 103 that cooperates with the T-shaped block 92. The abutment block 103 is located on the inside of the square frame 101. A scale that cooperates with the abutment block 103 is provided on the side of the square frame 101 away from the connecting plate 5.

[0045] The side cross-section of the T-shaped block 92 is T-shaped, and the top surface of the T-shaped block 92 opposite to the connecting plate 5 is an inclined surface. The bottom surface of the abutting block 103 opposite to the T-shaped block 92 is an inclined surface, and the inclined surfaces of the abutting block 103 and the T-shaped block 92 are arranged parallel to each other.

[0046] Before activating the motor and using the contact assembly 6 and the switching mechanism 8, after the patient has put on the device, first rotate the threaded rod 102 by turning the knob. During the rotation of the threaded rod 102, the contact block 103 moves upward inside the square frame 101, thereby moving the contact block 103 to the top of the square frame 101. Then, manually pull the T-shaped rod 69 upward. While the T-shaped rod 69 moves upward, the air in the air tank 67 is filled into multiple air bladders 63 using the cooperation between the above-mentioned structures, causing the multiple air bladders 63 to inflate. At this time, the patient can adjust the device according to their individual needs. Use your sense of touch or chest size to determine the degree of inflation of the airbag 63, that is, how much air is inflated into the airbag 63. When the usage requirement is met, you can notify the movement of the T-shaped rod 69. At this time, you can observe the specific position of the T-shaped block 92 on one side of the T-shaped rod 69 on the side of the square frame 101 and make a record on the scale. Then release the T-shaped rod 69 and rotate the threaded rod 102 in the opposite direction by turning the knob, so that the abutment block 103 moves down outside the threaded rod 102, so that the abutment block 103 moves to the marked position, thereby completing the specific adjustment of the inflation amount of the airbag 63.

[0047] After the above adjustments are completed, the micro motor 85 can be turned on, causing the micro motor 85 to drive the T-shaped block 92 upward through the cooperation of the above structures. When the T-shaped block 92 moves upward to the position where it abuts the contact block 103, that is, the inflation volume inside the airbag 63 has reached the above setting. At this time, the contact block 103 pushes the T-shaped block 92 into the T-shaped rod 69 through the abutment between the contact block and the T-shaped block 92 and compresses the spring, so as to release the abutment between the T-shaped block 92 and the top block 94. At this time, the T-shaped block 92 is in the cooperation of the above structures. The airbag 63 is retracted into the air tank 67 as the airbag 63 is lowered and reset, causing the airbag 63 to shrink. When the top block 94 moves down with the toothed plate 89, when the top block 94 moves to the position of contacting the T-shaped block 92, it first pushes the T-shaped block 92 into the interior of the T-shaped rod 69 and squeezes the second spring 93 through the contact action between the top block 94 and the inclined surface of the T-shaped block 92. Then, when the top block 94 moves to the bottom of the T-shaped block 92, the T-shaped block 92 moves outward and resets under the extension and reset action of the second spring 93.

[0048] The present invention, by providing an adjustment mechanism 10, can flexibly adjust the inflation volume of the close-fitting mechanism according to the patient's usage and chest size, which can effectively improve the patient's experience when using the close-fitting mechanism, increase the flexibility of the close-fitting mechanism, and increase the overall practicality of the breast care equipment.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
