Description

Technical Field

[0001] This invention relates to postoperative rehabilitation aids technology, specifically to a shaping bra to prevent displacement after breast cancer implantation. Background Technology

[0002] Breast cancer is one of the most common malignant tumors in women. Patients who undergo mastectomy and implant placement often need to wear special shaping bras post-surgery to prevent implant displacement and promote wound healing and recovery. Currently, post-operative shaping bras on the market mainly include two types: elastic fabric compression bras and single-balloon inflatable bras.

[0003] Elastic fabric compression bras rely on the overall elastic fabric to apply uniform pressure to the chest and back. Although they are simple in structure and low in cost, they have the problem of uneven pressure distribution. They are difficult to provide differentiated support for the implant projection area, the boundary of the pectoralis major muscle, and the axillary lymph node dissection area, which can easily cause local pressure pain or implant displacement. At the same time, these products lack dynamic pressure adjustment capabilities and cannot automatically optimize the support according to changes in the patient's body position (such as sitting, standing, lying down, and exercising).

[0004] like Figure 1 As shown, in order to solve the problem of uneven pressure in elastic fabric compression bras, the prior art has proposed an inflatable bra. This inflatable bra provides support through a single integral air bladder or several simple zoned air bladders, which improves the adjustability of pressure distribution to a certain extent.

[0005] For example, 1) a post-masturbation bra disclosed in patent application CN221083978U includes a protective bra with an inflatable assembly attached to its outer side. The inflatable assembly includes a moving strap and an inflatable airbag. A pressure airbag is fixedly mounted on the inner side of the protective bra, and the pressure airbag includes a second bladder and a valve core. This invention provides multiple pressure airbags fixedly mounted on the inner side of the protective bra. When applying pressure dressing to the wound of a breast surgery patient using the protective bra, the external inflatable airbags inflate the pressure airbags, causing them to expand and apply pressure to the wound. This is convenient to operate, provides stable pressure, and allows for targeted pressure application based on different wound locations, improving the dressing effect. Furthermore, the inflatable airbags are attached to the inner side of the moving strap, and the two ends of the moving strap are attached to the outer side of the protective bra. During use, the moving strap can be easily moved around the protective bra to inflate the pressure airbags at different locations, making operation convenient.

[0006] 2) Publication No. CN118021524A discloses a pressure bandage bra for post-mastectomy breast cancer. This patent application includes two bra bodies, with a first connecting strap fixedly installed on the side of each bra body furthest from the others. The first connecting strap has a tightening structure, to which a first elastic band is connected. An inflation device is located at the bottom of the bra body, and the bra body contains filling fabric and a second airbag. This invention, through its tightening structure, allows the patient to rotate a turntable after wearing the bra, causing a third connecting shaft, a worm gear, and a second connecting shaft to rotate. Because the worm gear meshes with the turbine, it drives the turbine to rotate, thereby causing the first connecting shaft and the tightening wheel to rotate, thus tightening or releasing the first elastic band. This allows for adjustment of the bra's tightness according to the patient's breast size, reducing the impact of an overly loose or tight bra on post-operative recovery.

[0007] While the inflatable bras described above provide adjustable pressure to some extent through their airbag structure, their functional design primarily focuses on static compression and bandaging of postoperative wounds, or basic mechanical adjustment of tightness. However, they generally suffer from the following common defects:

[0008] First, its airbag layout is not precisely matched with the key anatomical structures after implantation (such as the implant boundary, the pectoralis major muscle insertion point, and the lymphatic drainage path), which makes it impossible to achieve three-dimensional and zoned stable support for the implant and has limited anti-displacement effect.

[0009] Secondly, the pressure control methods are mostly manual or simple mechanical inflation and deflation, lacking an intelligent closed-loop control system based on real-time body position monitoring and multi-area pressure feedback. This makes it unable to dynamically adapt to changes in the patient's posture during daily activities, resulting in insufficient comfort and safety.

[0010] More importantly, existing solutions do not integrate proactive prevention and treatment of common and serious post-operative complications of breast cancer, such as axillary and back lymphedema. Their functions are limited and fail to achieve integrated intelligent rehabilitation that combines prosthesis stabilization, dynamic adaptation, and lymphedema management. Summary of the Invention

[0011] The purpose of this invention is to provide a post-operative anti-displacement shaping bra for breast cancer implantation, in order to solve the problems of limited anti-displacement effect, difficulty in dynamically adapting to changes in body position, and single function in the prior art.

[0012] To achieve the above objectives, the present invention provides the following technical solution: a post-operative anti-displacement shaping bra for breast cancer implantation, comprising a front bra piece and a back bra piece formed by heat-pressing elastic bands, wherein:

[0013] The front panel of the bra corresponds to one or both breast areas of the human body. Its inner side has multiple independently positioned air bladders made of medical-grade polyurethane film. The inner surface of the air bladder, which contacts the human skin, has a skin-friendly lining. The air bladders include:

[0014] The anterior main capsule, corresponding to the prosthesis projection area, is used to support and stabilize the prosthesis;

[0015] The lateral fixation capsule is set longitudinally along the lateral border of the pectoralis major muscle and the anterior axillary line, and extends to the axillary lymph node dissection area. It is used to wrap and fix the prosthesis from the side to prevent it from migrating.

[0016] The lower support pouch is designed in an arc shape along the inframammary fold to support the implant from below and prevent sagging.

[0017] The upper edge fitting capsule is set in an arc along the subclavian region to gently press down from above to prevent the implant from shifting upwards;

[0018] The back panel of the bra is secured with elastic straps or is made of a single piece of elastic fabric.

[0019] Furthermore, the inner side of the entire elastic fabric back panel is provided with a back support airbag structure to promote lymphatic return. The back support airbag structure includes a first main bag and a second main bag covering the upper and lower areas of the back. The first main bag and the second main bag are connected by a one-way valve. The interior of the first main bag and the second main bag is divided into multiple first sub-bags and second sub-bags along the lymphatic trunk by a flexible diaphragm. The first sub-bags are arranged along the direction from the lower angle of the scapula to the spine, and the second sub-bags are arranged along the direction from the side of the spine to the waist. The first sub-bags and the second sub-bags are connected to the main air passage through independent solenoid valves and form a time-division pressure controllable pneumatic drive unit.

[0020] Furthermore, the front and back panels of the bra are pre-embedded with a flexible catheter network corresponding to the inflation bladder, the first main bladder, and the second main bladder. This flexible catheter network connects to the integrated control module, the inflation bladder, the first main bladder, and the second main bladder. The integrated control module includes a miniature multi-channel air pump, a solenoid valve array, a microprocessor, and a power supply unit. The miniature multi-channel air pump, solenoid valve array, microprocessor, and power supply unit can independently, zonedly, and rapidly deliver and control air pressure to each bladder, enabling synchronous or time-sequential inflation and deflation in multiple areas. This allows for precise adjustment of support and fit in different areas, ensuring the prosthesis is stable and prevents displacement. Simultaneously, it can provide directional gradient pressure to the posterior lymphatic drainage area, improving wearing comfort and the responsiveness and reliability of intelligent rehabilitation.

[0021] Furthermore, motion sensors are installed within the shoulder straps of the bra's front panel. These sensors monitor real-time changes in the user's posture (including standing, sitting, lying down, and light activity). The motion sensor is a nine-axis inertial measurement unit (MPU-9250), which integrates a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer. It can detect the acceleration, angular velocity, and orientation information of the shoulder strap position in real time, and calculate the user's posture using a built-in algorithm. The resulting digital signal is then sent to the microprocessor for linkage with the airbag pressure control.

[0022] Furthermore, the inner surfaces of the first and second cysts are integrated with a first micro pressure sensor and a flexible electrothermal film, which can monitor and precisely regulate the pressure of each zone in real time to prevent local pressure discomfort or ischemia. At the same time, the flexible electrothermal film provides safe thermal therapy, promotes local circulation and lymphatic flow, relieves postoperative muscle tension and edema, and achieves active intelligent rehabilitation with synergistic pressure and temperature.

[0023] Furthermore, a second micro-pressure sensor is integrated into the inner surface of the lateral fixation capsule, the lower perimeter support capsule, and the upper edge fitting capsule. This sensor can monitor the pressure distribution in the key support areas of the prosthesis's sides, lower perimeter, and upper edge in real time, accurately sense changes in the anti-displacement support force, and promptly provide feedback to the control system (microprocessor) to dynamically adjust the air pressure in each area. This ensures the prosthesis is stable and prevents displacement while avoiding excessive or insufficient local pressure, thus improving wearing comfort, fixation reliability, and the safety of postoperative recovery.

[0024] Furthermore, the anterior main capsule is divided into multiple independent annular array sub-airbags by a flexible radial diaphragm. These sub-airbags are distributed concentrically or spirally around the prosthesis projection area. This allows for independent support and zoned pressure control in different circumferential directions of the prosthesis, ensuring it conforms to the prosthesis contour, stabilizes its position, and prevents rotation or displacement. It also allows for fine-tuning based on the stress differences in each area, improving anti-displacement accuracy and shaping fit.

[0025] Furthermore, a third micro pressure sensor is provided on the inner surface of each annular array sub-airbag to monitor and fine-tune the circumferential pressure of the prosthesis.

[0026] Compared with existing technologies, this invention provides a post-operative anti-displacement shaping bra for breast cancer implantation. It combines a multi-zone independent inflatable bladder assembly in the front piece with the main and daughter bladders in the rear piece. Utilizing zoned intelligent inflation control, flexible electrothermal film heating, air pressure pulse massage, and posture sensing linkage, it can achieve precise differentiated support and dynamic pressure adjustment in the implant projection area, pectoralis major muscle boundary, and axillary lymph node dissection area. Furthermore, it integrates functions to promote lymphatic drainage, relieve muscle spasms, and correct posture. In particular, it can automatically optimize support and actively prevent postoperative lymphedema in different body positions and recovery stages. Specific technical effects include the following:

[0027] 1. Through independent pressure control of the multi-balloon anatomically zoned front piece, combined with real-time body position monitoring, the bra can automatically adjust the pressure distribution of each area according to the patient's different states such as sitting, standing, lying down, and exercising, effectively preventing the prosthesis from shifting, rotating or sagging during various daily activities, and significantly improving the reliability and safety of fixation.

[0028] 2. A directional drainage airbag structure based on a main bladder + daughter bladder structure was designed on the back. This structure can simulate professional lymphatic drainage techniques. By controlling the periodic inflation and deflation sequence of each daughter bladder, a gradient pressure wave is generated along the lymphatic return path (such as from the lower back to the armpit), thereby actively promoting lymphatic fluid return. It is especially effective for areas with high postoperative edema, such as the interscapular region, and achieves wearable, continuous physical therapy.

[0029] 3. Through the collaboration of a distributed pressure sensor network and motion sensors, the bra can collect real-time data on the patient's posture and local pressure, and dynamically adjust the pressure according to a preset algorithm. This not only optimizes the immediate comfort of the patient but also allows treatment parameters to be personalized according to individual differences and recovery stages, improving the adaptability of postoperative rehabilitation.

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] As attached Figure 2 To be continued Figure 3 As shown:

[0040] Example 1:

[0041] This invention provides a post-operative anti-displacement shaping bra for breast cancer implantation, comprising a front piece 1 and a back piece 2 formed by heat-pressing elastic bands. The front piece 1 corresponds to one or both breast regions and has multiple independently positioned airbags on its inner side. These airbags are made of medical-grade polyurethane film, and their inner surface, which contacts the skin, has a skin-friendly lining. The airbags include:

[0042] The anterior main capsule 3, corresponding to the prosthesis projection area, is used to support and stabilize the prosthesis;

[0043] The lateral fixation capsule 4 is set longitudinally along the lateral border of the pectoralis major muscle and the anterior axillary line, and extends to the axillary lymph node dissection area. It is used to wrap and fix the prosthesis from the side to prevent it from migrating.

[0044] The lower support pouch 5 is set in an arc along the inframammary fold to support the implant from below and prevent sagging;

[0045] The upper edge fitting capsule 6 is set in an arc along the subclavian region to gently press down from above to prevent the implant from shifting upwards;

[0046] The back panel 2 of the bra features an elastic strap for fixation.

[0047] 1. In one embodiment of the present invention, a flexible conduit network corresponding to the airbag is pre-embedded on the inner side of the front piece 1 of the bra. The flexible conduit network is connected to the integrated control module and the airbag. The integrated control module includes a miniature multi-channel air pump, a solenoid valve array, a microprocessor, and a power supply unit. The miniature multi-channel air pump, solenoid valve array, microprocessor, and power supply unit can independently, zonedly, and rapidly deliver and control air pressure to each airbag, realizing synchronous or time-sharing inflation and deflation of multiple areas. This allows for precise adjustment of the support and fit of different parts, ensuring the stability of the prosthesis and preventing displacement. At the same time, it can implement directional gradient pressure drive to the posterior lymphatic drainage area, improving wearing comfort and the response speed and reliability of intelligent rehabilitation.

[0048] 2. In one embodiment of the present invention, a motion sensor is provided within the shoulder strap of the front piece 1 of the bra. The motion sensor is used to monitor changes in the user's posture in real time (including standing, sitting, lying, and light activity). The motion sensor is a nine-axis inertial measurement unit, model MPU-9250. This sensor integrates a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer. It can detect the acceleration, angular velocity, and orientation information of the shoulder strap position in real time, and calculate the user's posture through a built-in algorithm, outputting digital signals to the microprocessor to achieve linkage with the airbag pressure control.

[0049] 3. In one embodiment of the present invention, a second micro pressure sensor (not shown in the figure) is integrated on the inner surface of the lateral fixation capsule 4, the lower perimeter support capsule 5, and the upper edge fitting capsule 6. This sensor can monitor the pressure distribution in the key support areas of the prosthesis's sides, lower perimeter, and upper edge in real time, accurately sense changes in the anti-displacement support force, and promptly provide feedback and coordinate with the control system (microprocessor) to dynamically adjust the air pressure in each area. This ensures the prosthesis is stable and prevents displacement while avoiding excessive or insufficient local pressure, thus improving wearing comfort, fixation reliability, and the safety of postoperative recovery.

[0050] Working Principle: Example 1 utilizes a multi-zone independent inflation system with anterior main pocket 3, lateral fixation pockets 4, lower support pockets 5, and upper edge fitting pockets 6 within the front panel. A nine-axis inertial measurement unit is integrated into the shoulder straps to monitor body posture in real time. Combined with feedback from second micro-pressure sensors on the lateral fixation pockets 4, lower support pockets 5, and upper edge fitting pockets 6, a smart bra solution with three-dimensional implant anti-displacement and dynamic pressure adjustment capabilities is constructed. This bra can independently and zone-wise inflate and deflate each pocket through an integrated control module. Whether the user is standing, sitting, lying down, or engaging in light activity, it automatically adjusts the support force in each area based on real-time posture and pressure data, ensuring the implant is stable, prevents displacement, and provides a comfortable fit. In particular, it can instantly compensate for pressure distribution differences during changes in body position or daily activities, significantly improving the stability and safety of postoperative recovery.

[0051] As attached Figure 4 As shown:

[0052] Example 2:

[0053] This embodiment is basically the same as the previous embodiment, except that the anterior main capsule 3 is divided into multiple independent annular array sub-airbags 301 by a flexible radial diaphragm. These multiple annular array sub-airbags 301 are distributed in a concentric circle or spiral shape around the projection area of ​​the prosthesis. This allows for independent support and zoned pressure control in different circumferential directions of the prosthesis, which can both conform to the contour of the prosthesis to stabilize its position and prevent rotation or displacement, and also allow for fine-tuning according to the force differences in each area, improving the accuracy of anti-displacement and the fit of the shaping.

[0054] 1. In one embodiment of the present invention, a third micro pressure sensor 302 is provided on the inner surface of each annular array sub-airbag 301 to monitor and fine-tune the circumferential pressure of the prosthesis.

[0055] Working principle: Since Embodiment 1 has already set the anterior main capsule 3, lateral fixation capsule 4, lower support capsule 5 and upper edge fitting capsule 6 in the front piece 1 of the bra to achieve multi-directional fixation of the prosthesis and basic anti-displacement function, Embodiment 2, on the basis of the above, further divides the anterior main capsule 3 into multiple independent annular array sub-capsules 301 by a flexible radial diaphragm, and distributes them in a concentric circle or spiral shape around the projection area of ​​the prosthesis. With the third micro pressure sensor 302 set on the inner side of each sub-capsule, independent support and zoned pressure control of different circumferential directions of the prosthesis can be achieved. This not only can it fit the contour of the prosthesis more closely and prevent its rotation or displacement, but it can also make fine adjustments according to the force difference of each area. Thus, on the basis of the all-round fixation capability of Embodiment 1, it further improves the anti-displacement accuracy and the fit of postoperative shaping.

[0056] As attached Figure 5 As shown:

[0057] Example 3:

[0058] This embodiment is basically the same as the previous embodiment, except that the back panel 2 of the bra is a single piece of elastic fabric. The inner side of the single piece of elastic fabric back panel is provided with a back support airbag structure to promote lymphatic drainage. This back support airbag structure includes a first main airbag 7 and a second main airbag 8 covering the upper and lower areas of the back. The first main airbag 7 and the second main airbag 8 are connected by a one-way valve. The interior of the first main airbag 7 and the second main airbag 8 is divided into multiple first sub-airbags 9 and second sub-airbags 10 along the lymphatic trunk direction by a flexible diaphragm. The first sub-airbags 9 are arranged along the direction from the lower angle of the scapula to the spine, and the second sub-airbags 10 are arranged along the direction from the side of the spine to the waist. The first sub-airbags 9 and the second sub-airbags 10 are connected to the main airway through independent solenoid valves, forming a time-division and pressure-controllable pneumatic drive unit.

[0059] 1. In one embodiment of the present invention, a flexible conduit network corresponding to the airbags, the first main airbag 7, and the second main airbag 8 is pre-embedded on the inner sides of the front piece 1 and the back piece 2 of the bra. The flexible conduit network is connected to the integrated control module, the airbags, the first main airbag 7, and the second main airbag 8. The integrated control module includes a miniature multi-channel air pump, a solenoid valve array, a microprocessor, and a power supply unit. The miniature multi-channel air pump, the solenoid valve array, the microprocessor, and the power supply unit can independently, zonedly, and rapidly deliver and control air pressure to each airbag, realizing synchronous or time-sharing inflation and deflation of multiple areas. This allows for precise adjustment of the support and fit of different parts, ensuring the stability of the prosthesis and preventing displacement. At the same time, it can implement directional gradient pressure drive to the posterior lymphatic drainage area, improving wearing comfort and the response speed and reliability of intelligent rehabilitation.

[0060] 2. In one embodiment of the present invention, the inner surfaces of the first cyst 9 and the second cyst 10 are integrated with a first micro pressure sensor and a flexible electrothermal film (not shown in the figure), which can monitor and precisely regulate the pressure of each zone in real time to prevent local pressure discomfort or ischemia. At the same time, the flexible electrothermal film provides safe thermal therapy, promotes local circulation and lymphatic flow, relieves postoperative muscle tension and edema, and realizes active intelligent rehabilitation with pressure and temperature synergy.

[0061] Working Principle: In Example 3, based on the aforementioned design, the back panel 2 of the bra is constructed as a single piece of elastic fabric. Inside, a back support airbag structure is added, consisting of a first main airbag 7, a second main airbag 8, and first and second sub-airbags 9 and 10 arranged along the lymphatic trunk. Combined with a pre-embedded flexible catheter network and an integrated control module, each airbag can be independently, zonedly, and rapidly supplied with and controlled air pressure, achieving time-division and pressure-controlled pneumatic drive of the back lymphatic drainage area. Simultaneously, a first micro-pressure sensor and a flexible electrothermal film are integrated inside the first and second sub-airbags 9 and 10, allowing for real-time monitoring and precise pressure adjustment to prevent local pressure discomfort or ischemia. Furthermore, thermal therapy promotes local circulation and lymphatic flow, alleviating postoperative muscle tension and edema. Therefore, in addition to the prosthesis stabilization and dynamic shaping capabilities of Example 2, Example 3 further enhances the active prevention and treatment of common post-mastectomy lymphedema, achieving integrated intelligent rehabilitation of prosthesis stabilization, dynamic adaptation, and lymphedema management, significantly improving wearing comfort and overall rehabilitation effectiveness.

[0062] In conjunction with the above embodiments one, two, and three, the present invention also provides the working process of the above-mentioned anti-displacement shaping bra after breast cancer implantation:

[0063] After the user wears the bra, the multi-zone air bladders (front main bladder 3, side wing fixation bladders 4, lower band support bladder 5, and upper edge fitting bladder 6) of the front panel 1, together with the elastic straps of the back panel or the entire elastic fabric back panel, form a support structure that conforms to the body. The motion sensors in the shoulder straps collect the user's posture information in real time and transmit it to the microprocessor. The micro pressure sensors on the annular array of sub-air bladders 301 of the side wing fixation bladders 4, lower band support bladders 5, upper edge fitting bladders 6, and front main bladder 3 synchronously monitor the pressure distribution in the corresponding areas. The microprocessor issues instructions to the integrated control module according to a preset algorithm, and the micro multi-channel air pump and solenoid valve array independently, zonedly, and rapidly inflates and deflates the corresponding air bladders to achieve synchronous or time-sharing pressure adjustment in multiple areas. This dynamically maintains the stable, anti-displacement, and comfortable support of the prosthesis when the user is standing, sitting, lying down, or engaging in light activity.

[0064] When the back panel 2 of the bra is a single piece of elastic fabric, the back support airbag structure (first main bladder 7, second main bladder 8 and their internal first daughter bladder 9 and second daughter bladder 10 along the lymphatic trunk) is connected to the same integrated control module through a flexible conduit network. The system can perform gradient inflation and deflation of each daughter bladder in the back according to a time-division pressure strategy, simulating professional lymphatic drainage techniques, and actively driving lymph fluid to flow back along the inferior angle of the scapula to the spine, and along the side of the spine to the waist. At the same time, the first micro pressure sensor on the inner side of each daughter bladder works in conjunction with the flexible electrothermal film to monitor the pressure in real time and apply safe heat therapy to promote local circulation and relieve muscle tension and edema.

[0065] Throughout the entire process, the bra uses closed-loop control based on real-time posture and pressure data to automatically optimize support and physiotherapy parameters during daily activities and different rehabilitation stages, achieving integrated intelligent rehabilitation that includes prosthesis stabilization and anti-displacement, dynamic shaping, and active prevention and treatment of lymphedema.

[0066] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
