Description

Technical Field

[0001] The invention relates to the technical field of postoperative care, in particular to a special bra for breast surgery with adjustable pressure. Background Art

[0002] Due to changes in breast tissue structure, patients undergoing breast surgery have special requirements for bra comfort, pressure regulation, and breathability. In existing bra technology, pressure regulation methods are mainly categorized into two types: physical structural adjustment and gas exchange. Physical structural adjustment involves adjusting the shoulder strap length using buckles at both ends to change tightness, or using specially designed straps to increase effective tension, improving breast shaping and comfort. Gas exchange involves installing an injection device consisting of a gas exchange port, an injection tube, and an injection bag in the bra to inject air into the chest pressure filler to adjust pressure.

[0003] Patent CN221654725 proposes a bra with adjustable pressure after breast tumor resection. However, the device has deficiencies in pressure regulation. Adjustment of the physical structure cannot achieve continuous and delicate adjustment, and it is difficult to meet the pressure requirements at different stages after surgery. Although the gas exchange method can adjust the pressure, it relies on manual operation of the air-filled bag and cannot monitor and automatically adjust the pressure in real time. In addition, the breathability of existing bras is poor due to unreasonable structural design. There is a lack of a good ventilation channel between the bra cup and the back cloth, which is not conducive to postoperative wound healing. The shoulder straps are mostly fixed by sewing or snap connections, which are inconvenient to install and disassemble, and inconvenient for patients to clean and replace parts.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1-6 As shown, an embodiment of the present invention provides a special bra for post-breast surgery with adjustable pressure, including a bra back cloth 2. The bra back cloth 2 is made of a four-way stretch fabric. The fabric is a blend of polyester fiber and spandex fiber, wherein the spandex fiber content is controlled at 3%-5%. The fabric can achieve multi-directional elastic stretch in the warp, weft and diagonal directions, thereby providing excellent four-way elastic performance. The shape of the bra back cloth 2 is designed to be an arc structure that fits the curve of the human back to ensure that it can fit evenly on the human back when worn, providing stable support and good comfort.

[0031] The bra cup 1 is also made of the same four-way stretch fabric as the bra back fabric 2. Each bra cup 1 is connected to the left and right ends of the bra back fabric 2 through precise cutting and seamless textile technology. This seamless textile technology eliminates the stitching in the traditional sewing process, making the bra smoother when in contact with the skin, reducing friction and marks, and effectively reducing the risk of skin allergies and discomfort. It is especially suitable for the sensitive skin of patients after breast surgery.

[0032] An upper opening 102 is provided between the bra cup 1 and the bra back fabric 2. The design of the opening fully takes into account the special needs of the armpit area of ​​patients after breast surgery. The shape and size of the upper opening 102 are carefully calculated to ensure that a good breathable environment is provided for the armpit wound during wearing, which helps the wound heal and reduces the risk of infection.

[0033] The shoulder strap 3 is an important component connecting the bra cup 1 and the bra back fabric 2. Its structural design takes into account support, comfort and ease of adjustment. The width of the shoulder strap 3 has been ergonomically optimized, which can provide sufficient support to reduce shoulder pressure without affecting the flexibility and aesthetics of wearing due to being too wide. The inner wall of the shoulder strap 3 is covered with soft, skin-friendly material to ensure comfort when in contact with the shoulder skin.

[0034] The lower side wall of the shoulder strap 3 is connected to the pressure regulating component 5 through Velcro 501. The Velcro 501 consists of a Velcro fleece surface and a Velcro hook surface. The Velcro hook surface is fixed to the inner side wall of the shoulder strap 3, and the Velcro fleece surface is fixed to the outer shell of the pressure regulating component 5. This connection method makes the installation and disassembly of the pressure regulating component 5 extremely simple. The user can easily adjust the position of the pressure regulating component 5 according to their own needs, or quickly disassemble it when cleaning is needed.

[0035] In addition, the front side wall of the shoulder strap 3 is connected to the tension measuring component 4 through two sets of male and female buckles. The male and female buckles include a first male buckle 4011, a second male buckle 402 and two female buckles. The first male buckle 4011 is fixed to the inner side wall of the sliding inner block 401, the second male buckle 402 is fixed to the inner side wall of the tension measuring component 4, and the two female buckles are fixed to the outer side wall of the shoulder strap 3. This connection method not only ensures a firm connection between the tension measuring component 4 and the shoulder strap 3, but also allows the user to flexibly adjust the position of the tension measuring component 4 according to actual needs to achieve the best measurement effect.

[0036] The pressure regulating assembly 5 is one of the core components of the present invention. Its outer shell is composed of a fixed sleeve 502, an intermediate connecting sleeve 503 and an elastic sleeve 504. The fixed sleeve 502 and the intermediate connecting sleeve 503, and the intermediate connecting sleeve 503 and the elastic sleeve 504 are fixedly connected by elastic connecting pads. The setting of the elastic connecting pad enables the pressure regulating assembly 5 to adapt to a certain deformation, so that when the shoulder strap 3 is stretched or contracted, it can be telescopically adjusted accordingly to ensure the stability and effectiveness of the pressure regulation. The elastic sleeve 504 is made of a flexible silicone material. This material not only has good elasticity, but also provides a comfortable touch, reducing the pressure and friction on the shoulders.

[0037] The pressure regulating component 5 integrates a micro air pump 506, a control main board 507 and a power supply component 505. The output end of the micro air pump 506 is fixedly connected to the telescopic airbag 508, and can pump gas into the telescopic airbag 508, thereby accurately adjusting the air pressure of the airbag. The cross-section of the telescopic airbag 508 is designed to be crescent-shaped, and is composed of multiple crescent-shaped sub-airbags. This unique structural design enables the telescopic airbag 508 to expand and contract evenly during inflation and deflation, ensuring the uniformity of pressure distribution. An air outlet valve 509 is provided inside the side wall of the telescopic airbag 508. When the air pressure needs to be reduced, the air outlet valve 509 can discharge the gas in time and quickly respond to the user's adjustment needs.

[0038] The control motherboard 507 is responsible for coordinating the workflow of the entire pressure regulating component 5. It establishes a stable electrical connection between the micro air pump 506, the power supply component 505 and the microcontroller 405 of the tightness measuring component 4. By receiving signals from the tightness measuring component 4, the control motherboard 507 can intelligently control the working state of the micro air pump 506 and realize the automatic pressure regulation function.

[0039] The tightness measuring component 4 is a key component for realizing automatic adjustment of bra pressure. Its internal structure is precisely designed and can accurately sense the tightness changes of the shoulder strap 3. The sliding inner groove 403 constitutes the basic structure of the tightness measuring component 4, and its internal sliding connection is connected with the sliding inner block 401. The sliding inner block 401 can slide freely in the sliding inner groove 403, and reflect the actual tightness state of the shoulder strap 3 through relative displacement with the shoulder strap 3.

[0040] A high-precision Hall sensor 404 is installed on the inner wall of the sliding inner groove 403, and a magnetic block 4012 is fixedly connected to the inner wall of the sliding inner block 401. When the shoulder strap 3 is extended or retracted, the relative distance between the magnetic block 4012 and the Hall sensor 404 changes, resulting in a change in the magnetic field strength. The Hall sensor 404 can keenly detect the change in the magnetic field strength and convert it into an electrical signal.

[0041] A microcontroller 405 is also provided inside the tightness measurement component 4. A stable connection is established between the microcontroller 405 and the Hall sensor 404 through an electrical circuit. The microcontroller 405 receives the electrical signal from the Hall sensor 404 and accurately analyzes and processes it. Based on a pre-set pressure adjustment algorithm, the microcontroller 405 calculates the current tightness of the shoulder strap 3 and determines whether the bra pressure needs to be adjusted.

[0042] A reliable electrical connection is also established between the microcontroller 405 and the control mainboard 507 in the pressure regulating component 5. The power supply component 505 provides stable power support for the entire signal transmission and processing process. When the microcontroller 405 determines that the pressure needs to be adjusted, it will promptly send a control signal to the control mainboard 507 to trigger the operation of the micro air pump 506 or the air outlet valve 509, thereby achieving precise adjustment of the bra pressure. The entire process is highly automated and can respond to changes in the tightness of the shoulder strap 3 in real time, ensuring that the bra always remains within an appropriate pressure range, providing the best wearing experience for patients after breast surgery.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
