Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to a bra with adjustable pressure after breast tumor removal. Background Art

[0002] Breast lumpectomy is a surgical procedure for benign or malignant breast tumors. The core goal of this surgery is to remove abnormal lumps in the breast and preserve healthy tissue in the breast as much as possible to ensure the function and appearance of the breast. The surgical steps are roughly as follows: local anesthesia, precise positioning of the lump, and then removal of the lump. The surgical method will vary depending on the location and size of the tumor. For example, if the tumor is located under the areola or nipple, radial surgical incisions need to be made in the direction of the milk ducts; if it is in the breast, the incision direction is along the skin folds of the breast. The removed tissue will be sent to the hospital's pathology department for testing to determine the type and nature of the tumor.

[0003] After breast lumpectomy, especially after partial or complete removal of the breast, the patient's body will undergo some changes. With current technology, it is often recommended that patients wear prosthetic breasts for auxiliary rehabilitation treatment.

[0004] Prosthetic breasts, also known as silicone prosthetic breasts or surgical false breasts, are special rehabilitation products for breast cancer surgery and have a certain load-bearing capacity. The weight of the prosthetic breast is very close to the weight of the normal breast on the opposite side, which can maintain the body balance after surgery and prevent torticollis, oblique shoulders and scoliosis caused by the asymmetry of the weight of the left and right breasts after surgery. Prosthetic breasts can effectively fill the physical defects of women after breast surgery, maintain the beauty of women's body, and help women who have lost their breasts regain their style. Wearing prosthetic breasts can relieve the psychological pressure caused by breast loss and enhance the patient's self-confidence in life. The elasticity of the prosthetic breast can buffer and prevent external forces from damaging the chest, especially when the elasticity of the chest skin decreases significantly after surgery, the silicone prosthetic breast can effectively protect the chest.

[0005] However, in the prior art, in order to avoid the weight or shape being too different from the normal breast weight or shape of the patient, silicone custom breast prostheses are often used for making breast prostheses. The preparation cycle of silicone custom breast prostheses is long and the customization price is relatively high. At the same time, silicone breast prostheses are difficult to adapt to the pressure requirements of different positions of patients, which easily affects the wearing comfort and increases the pain of patients.

[0034] The following is further described in detail through specific implementation methods:

[0035] Embodiment 1:

[0036] As attached Figure 1 -Attached Figure 6 As shown: A bra with adjustable pressure after breast tumor removal surgery, including a fixing component 1, on which an adjustment component 3 is provided, the adjustment component 3 is used to apply different amounts of pressure to the patient's wound, and the fixing component 1 is used to limit the relative position of the patient's wound and the adjustment component 3.

[0037] A communication module is provided on the fixing component 1, and the fixing component 1 includes a bra main body. The communication module is bonded and fixed to the bra main body. In this embodiment, the communication module is a Bluetooth module, which is used to transmit signals to the user's mobile phone client, etc. The inner side wall of the bra main body is provided with symmetrically arranged cups 11, and the cups 11 are bonded and detachably connected to the bra main body.

[0038] The adjustment component 3 includes a storage cavity 38, which is arranged in any cup 11. A plurality of adjusters 32 are arranged in the storage cavity 38. The adjusters 32 are used to adjust the overall weight of the adjustment component 3. The adjusters 32 are liquids, and the adjustment component 3 includes a pump assembly. In this embodiment, the pump assembly is a water pump. The pump assembly is detachably connected and communicated with the storage cavity 38. A first solenoid valve is provided at the connection between the pump assembly and the storage cavity 38, and the pump assembly is also connected to a liquid storage bottle, which is used to store the adjusters 32.

[0039] A plurality of fixing plates 2 made of elastic material are provided on the side of the cup 11 close to the patient, and the fixing plates 2 are detachably connected to the patient's chest skin by bonding.

[0040] It also includes a control system, which includes a flow sensor, a controller and a plurality of first strain gauges. The controller is bonded and fixed to the bra body, the first strain gauges are bonded and fixed to the fixing plate 2, the flow sensor is fixed to the pump assembly by bolts, and the first strain gauge, the pump assembly, the first solenoid valve, the flow sensor and the communication module are all electrically connected to the controller.

[0041] The first strain gauges are used to collect the first deformation information of the fixing plate 2 .

[0042] The flow sensor is used to collect flow information of the regulator 32 entering the storage chamber 38 = the controller is used to receive the initial weight of the regulating component 3 and the density of the regulating component 32 input by the user, and obtain the patient's skin elastic modulus based on the first deformation information of the fixed plate 2 on the side close to the regulating component 3 and the initial weight of the regulating component 3, and calculate the weight difference between the patient's breasts on both sides in combination with the first deformation information of the fixed plate 2 on the side away from the regulating component 3 and the position of the fixed plate 2 where the first deformation information occurs, and calculate the maximum pressure required by the patient based on the weight difference, and control the communication module to output prompt information to the user, and when the overall weight of the regulating component 3 is the same as the maximum pressure, control the communication module to alarm the user, and the controller controls the operation of the pump component based on the flow information, the density of the regulator 32, the initial weight of the regulating component 3 and the maximum pressure.

[0043] The specific implementation process is as follows: when using the device, the cup 11 is adjusted or replaced according to the position of the breast tumor that has been removed. The cup 11 with the storage cavity 38 is placed close to the breast on which the breast has been removed. After the bra is put on, the patient lies flat so that the breast is naturally flat. Then, the fixing plates 2 are adhered to the skin of the chest above the breasts on both sides, and the fixing plates 2 on both sides are symmetrically arranged along the sagittal section of the patient. After the fixation is completed, the patient starts the device, moves the adjustment component 3 away from the chest, and gradually stands up until the upright state is restored. After a certain period of time after the upright state is restored, the bra body 12 is adjusted so that the adjustment component 3 naturally acts on the breast on the side where the breast tumor has been removed.

[0044] During this process, the first strain gauge continuously collects the first deformation information of the fixing plate 2. When the patient stands upright, under the action of gravity, the patient's breast gradually changes from the original flat state to a sagging state. On one side of the patient's normal breast, since the mammary gland and other tissues have a certain weight, when the patient stands, the skin on the patient's chest is pulled, causing the skin at this position to be stretched. Since the fixing plate 2 is completely attached to the patient's skin at this position, the skin at this position is stretched, which also drives the fixing plate 2 to stretch.

[0045] As for the patient's breast at the wound site, during this process, the stretching of the skin at the patient's chest is caused by the remaining breast. After the adjustment component 3 is applied to the breast, the stretching of the skin at the patient's chest is caused by the total weight of the patient's remaining breast and the adjustment component 3.

[0046] In the initial state, no adjustment object 32 is placed in the storage cavity 38, and the weight of the adjustment component 3 is known, that is, the magnitude of the force applied to the skin at the patient's chest position on the side where the storage cavity 38 is provided is known, and the elastic modulus of the fixing plate 2 is also known. At this time, according to the first deformation information of the fixing plate 2 on the side where the storage cavity 38 is provided, the deformation amount of the fixing plate 2 at this position can be obtained, so that the elastic modulus of the patient's skin at this position can be calculated. After obtaining the elastic modulus of the patient's skin, according to the first deformation information of the fixing plate 2 on the other side, the magnitude of the force applied to the skin at this position on the other side can be calculated, and combined with the first deformation information corresponding to the residual breast tissue, the difference in weight of the breasts on both sides can be obtained.

[0047] In order to avoid problems such as scoliosis caused by inconsistent body weight on both sides of the patient, a similar weight needs to be applied to the side of the patient where the breast has been removed. That is, the total weight of the adjustment module needs to be adjusted to the same as the difference in weight between the patient's two breasts, where the weight adjusted by the adjustment component is the maximum pressure.

[0048] At this time, the controller controls the communication module to work and outputs a prompt message to the patient. At this time, the patient connects the pump assembly with the storage chamber 38, and starts the pump assembly and the first solenoid valve. Through the operation of the pump assembly, the regulator 32 in the liquid storage bottle is pumped into the storage chamber 38. At the same time, the flow sensor continuously collects the flow information of the regulator 32 pumped into the storage chamber 38. Since the density of the regulator 32 is known, the weight of the regulator 32 entering the storage chamber 38 can be obtained according to the flow information. When the weight of the regulator 32 is the same as the maximum pressure, the controller controls the first solenoid valve to close, stops the pump assembly, and controls the communication module to alarm the user, prompting the user to remove the pump assembly.

[0049] At this time, the controller again determines the deformation amount of the patient's skin caused by the regulator 32 entering the storage cavity 38 based on the first deformation information, and determines whether the skin deformation amounts above the patient's breasts on both sides are the same. If the difference between the two data is large, the controller again controls the communication module to alarm the user, prompting the user to adjust again until it is adjusted to the appropriate weight.

[0050] After adjusting to a suitable weight, the user removes the pump assembly and the like to complete wearing of the device.

[0051] The design of the fixing plate 2 and the like in the present device reacts to the deformation of the patient's skin through the deformation of the fixing plate 2, and determines the size of the adjustment pressure required by the patient according to the deformation of the patient's skin. Compared with the prior art, the present solution can adapt to patients with different degrees of mastectomy. Compared with traditional customized silicone breast prostheses, the present solution can quickly adapt to the patient's wound status, achieve rapid adaptation, shorten the time for preparing the breast prosthesis, and help reduce the pain of the patient during recovery.

[0052] At the same time, the design of the fixing plate 2 in the present solution reduces the probability of relative displacement between the adjustment component 3 and the patient's body during use by bonding it to the patient's skin, thereby reducing the discomfort caused to the patient by the shaking caused by inertia during use, which helps to improve the patient's acceptance of the device.

[0053] In this solution, the regulator 32 is designed to be liquid. Compared with the regulator 32 in solid form, it can adjust the weight more accurately, thereby improving the accuracy of the device. The liquid design also makes the regulator 32 easier to store and measure, which helps to reduce the difficulty of using the device. The liquid can undergo corresponding deformation according to the patient's movements, thereby improving the simulation of the device.

[0054] At the same time, the detachably connected cup 11 in this solution can adapt to patients with different resection positions by replacing the position of the cup 11 provided with the adjustment component 3.

[0055] Embodiment 2:

[0056] As attached Figure 1 As shown, the difference from Example 1 is that the adjustment component 3 also includes a plurality of pressure rods, which are all slidably matched with the side wall of the cup 11 close to the patient, and are provided with tension springs 37, which are all bonded and fixed to adjacent pressure rods, and are all bonded and fixed to the side wall of the cup 11. The adjustment object 32 is also used to push the pressure rod to move, and a plurality of diaphragms 33 are provided in the storage cavity 38. The inner wall of the diaphragm 33 and the inner wall of the storage cavity 38 away from the patient constitute the adjustment cavity, and a permanent magnet 36 is embedded in the diaphragm 33.

[0057] The control system also includes a three-axis electromagnetic sensor, which is connected to the controller via a wireless signal. The three-axis electromagnetic sensor is used to obtain position information of the permanent magnet 36. The controller is used to obtain the patient's wound contour based on the position information and correct the maximum pressure based on the patient's wound contour.

[0058] An electromagnet 34 is embedded in the side wall of the regulating chamber away from the permanent magnet 36. The elastic modulus of the diaphragm 33 is smaller than that of the side wall of the regulating chamber. A second solenoid valve 35 is provided at the connecting parts of the regulating chambers. The electromagnet 34 is electrically connected to the controller, and the controller controls the operation of the electromagnet 34 and the second solenoid valve 35 according to the contour of the patient's wound.

[0059] A pressure pad 31 is bonded and fixed to one end of the pressure rod close to the patient, and a pressure sensitive adhesive is bonded and fixed to one end of the pressure pad 31 away from the pressure rod.

[0060] The specific implementation process is as follows: During the use of the device, according to the patient's wound status, if the wound is completely healed, no dressing is selected; if the wound is not completely healed, a suitable dressing is selected, etc., and pressure-sensitive adhesive is used to detachably connect it to the pressure pad 31. When the patient has finished wearing it, since the elastic modulus of the diaphragm 33 is smaller than the side wall of the adjustment cavity away from the patient, the adjustment object 32 entering the adjustment cavity at this time first pushes the diaphragm 33 to move. While the diaphragm 33 is deformed, it pushes the pressure rod to move, thereby driving the pressure pad 31 to apply pressure to the user's wound. At this time, the patient adjusts the position of the pressure pad 31 so that the pressure-sensitive adhesive acts on the non-wound position of the patient, and there is pressure-sensitive adhesive acting on the patient's normal skin. When the pressure pad 31 is squeezed on the patient's skin, due to the reaction force given to it by the patient's skin, it is difficult for the diaphragm 33 to continue to deform, and the adjustment object 32 entering the adjustment cavity subsequently pushes the adjustment object 32 inside it into other adjustment cavities.

[0061] During use, the three-axis electromagnetic sensor continuously collects the position information of the permanent magnet 36. According to the position of the permanent magnet 36, the size of the pressure rod and the pressure pad 31, the contour state of the patient's affected breast after surgery, that is, the patient's wound contour, can be roughly obtained. According to the patient's wound contour, the location of the patient's breast removal can be roughly located. If the wound location is concentrated in the patient's armpit and other positions, the maximum pressure obtained by the difference in weight of the two breasts at this time does not match the pressure actually required by the patient. At this time, the controller connects the position information of each permanent magnet 36 into a smooth curve. At this time, according to the patient's chest curve and the total weight of the current adjustment component 3, the ratio between the area of ​​the chest depression and the total weight of the adjustment component 3 is calculated, and then the approximate pressure required for the patient's armpit depression is calculated, and then the maximum pressure is corrected. Then the controller outputs prompt information to the patient according to the maximum pressure and controls the pump component and the first solenoid valve to work.

[0062] Since the permanent magnet 36 has a stable magnetic field, the signal collected by the three-axis electrical sensor is more obvious than that of other metal materials, thereby reducing the probability of misjudgment. By obtaining the contour of the patient's wound, the patient's breast tumor removal position can be roughly located, and the maximum pressure can be corrected according to the positioning result, so that the present invention can maintain a certain adjustment ability when facing patients with wounds distributed in the armpits or chests, etc., reducing the calculation error of the maximum pressure when facing these patients, and improving the accuracy of the present invention.

[0063] Moreover, compared with the solution of using a single chamber to store the regulator 32, the design of the regulator cavity can reduce the impact of the regulator 32 on the patient or the side wall of the storage cavity 38 under the action of inertia, thereby improving the wearing comfort of this solution.

[0064] At the same time, when the wound is located at the patient's armpit or chest, the controller controls the electromagnet 34 located at the patient's breast to work, and the electromagnet 34 generates magnetic force to attract the permanent magnet 36, thereby compressing the adjustment cavity at the corresponding position, prompting the adjustment object 32 of the adjustment cavity to enter the adjacent adjustment cavity under pressure. When the adjustment cavity is adjusted to a suitable size, the controller closes the second electromagnetic valve 35 connected to the adjustment cavity, thereby fixing the volume of the adjustment cavity, repeating the above steps, adjusting the adjustment object 32 to the patient's wound position, and applying pressure to the patient's wound position through the pressure rod. Compared with the prior art, this solution can apply different pressures to different positions of the patient's chest according to the position of the patient's wound. When facing some wounds that are not convenient to compress, it can maintain a sufficient compression effect. When facing normal parts that do not need to be compressed, it can avoid excessive compression force, causing discomfort to the patient, or other complications. And because the adjustment object 32 is moved to the wound position, it can visually fill the sunken skin after the tumor is removed as much as possible, reducing the difference in appearance between the two breasts. At the same time, since the regulator 32 is adjusted using a pressing solution, most of the air in the regulating chamber can be discharged, thereby further reducing the impact of the regulator 32 on the patient or the side wall of the storage chamber 38 under the action of inertia, improving the comfort of the device, and also increasing the service life of the solution.

[0065] Embodiment 3:

[0066] As attached Figure 1 As shown, the difference from Example 2 is that a second strain gauge is bonded and fixed on the side wall of the regulating cavity away from the film, and the second strain gauge is used to collect the second deformation information of the side wall of the regulating cavity away from the film. The second strain gauge is electrically connected to the controller, and the controller is also used to determine the motion state of the regulating object 32 according to the second deformation information, and control the electromagnet 34 and the second solenoid valve 35 to work according to the motion state of the regulating object 32.

[0067] The specific implementation process is as follows: when using this solution, the second strain gauge continuously collects the second deformation information of the side wall of the adjustment cavity away from the film. When the adjustment object 32 drives the adjustment cavity to deform, the film deforms before the other positions of the side wall of the adjustment cavity, thereby pushing the pressure rod and the like to compress the patient's skin. At this time, according to the position information and the second deformation information of the side wall of the adjustment cavity away from the film corresponding to the position information, the approximate outline of the prosthesis constructed for the patient by the adjustment component 3 can be obtained. After obtaining the patient's wound contour based on the smooth curve connected to each other according to the position information, the controller controls the electromagnet 34 and the second solenoid valve 35 to work according to the difference between the prosthesis contour and the wound contour, and adjusts the shape of each adjustment cavity until the prosthesis contour basically matches the wound contour, thereby further reducing the difference between the two breasts of the patient.

[0068] At the same time, during use, the controller can also judge the impact of the regulator 32 on the side wall of the regulating chamber under the action of inertia based on the second deformation information, so as to judge whether the regulator 32 in the regulating chamber will cause discomfort to the patient. Therefore, during use, as the patient moves, inertia causes the regulator 32 to impact the side wall of the regulating chamber. At this time, the second deformation information can reflect the magnitude of the impact force. If the impact force may cause discomfort to the patient, the controller controls the electromagnet 34 and the second solenoid valve 35 to work, so as to reduce the amount of the regulator 32 in the regulating chamber to avoid subsequent discomfort to the patient.

[0069] Embodiment 4:

[0070] As attached Figure 1 As shown, the difference from Example 3 is that the control system further includes an angular velocity sensor, which is bonded and fixed to the bra body 12, and is used to collect the user's posture information. The angular velocity sensor is electrically connected to the controller, and the controller controls the electromagnet 34 to work according to the posture information.

[0071] The specific implementation process is as follows: when using this device, the angular velocity sensor continuously collects the angle between the user and the horizontal plane, that is, the posture information. According to the angle between the user and the horizontal plane, the controller can judge the actual action of the user, such as changing from lying to sitting, bending over to standing, etc., so as to predict the trend of the user's movement, and then judge the position where the user may be impacted by the adjustment object 32, and control the operation of the electromagnet and the second solenoid valve 35 according to the judgment result, adjust the shape of the position adjustment cavity, remove the air inside it, etc., which can increase the impact factor caused by inertia and improve the wearing comfort of this solution.

[0072] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
