Description

Technical Field

[0001] The invention relates to the technical field of pressure bandaging, in particular to a pressure bandaging device after breast surgery. Background Art

[0002] Breast cancer is a malignant tumor that generally threatens women's health. Among its treatment methods, surgical removal of the tumor is the most common method. After surgery, in order to promote wound healing, reduce subcutaneous fluid accumulation and prevent skin flap necrosis, doctors usually apply pressure bandage to the surgical site.

[0003] Traditional pressure bandaging methods, such as using elastic bandages or chest straps, can provide a certain amount of pressure support, but there are many shortcomings. For example, these methods often require medical staff to frequently adjust the strength of the bandage to adapt to the physiological changes of the patient during postoperative recovery. This not only increases the workload of medical staff, but may also cause patients to feel uncomfortable during the adjustment process. In addition, traditional bandaging methods lack sensitive response to the patient's breathing dynamics and cannot automatically adjust the pressure according to the patient's breathing fluctuations. For example, when the patient inhales, the abdomen and chest will expand, and the patient's breast will be subjected to greater pressure. On the contrary, when the patient exhales, the abdomen and chest will contract, and the pressure on the patient's breast will be reduced, which affects the patient's comfort and recovery effect to a certain extent.

[0004] In order to address the deficiencies of the prior art, the present invention aims to provide a novel post-operative breast compression bandage device that can automatically sense the patient's respiratory dynamics and automatically adjust the bandage pressure according to these changes to provide a more personalized and comfortable post-operative care experience. The design of the device takes into account the patient's comfort and post-operative recovery needs, and aims to reduce the labor intensity of medical staff and reduce the risk of patient discomfort and complications through an automatic adjustment mechanism.

DETAILED DESCRIPTION

[0042] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] The present embodiment provides a postoperative breast pressure bandage device, which is mainly used to solve the problems existing in traditional pressure bandage methods, such as the use of elastic bandages or chest straps. Although they can provide a certain amount of pressure support, they have many shortcomings. For example, these methods often require medical staff to frequently adjust the bandage strength to adapt to the physiological changes of the patient during the postoperative recovery process. This not only increases the workload of medical staff, but may also cause the patient to feel uncomfortable during the adjustment process. In addition, traditional bandage methods lack sensitive response to the patient's breathing dynamics and cannot achieve the function of automatically adjusting the pressure according to the patient's breathing fluctuations. For example, when the patient inhales, the abdomen and chest will expand, and the patient's breast will be subjected to greater pressure. On the contrary, when the patient exhales, the abdomen and chest will contract, and the pressure on the patient's breast will be reduced, which affects the patient's comfort and recovery effect to a certain extent. In response to these problems, the following technical solutions are provided. Figure 1-Figure 14 Make a detailed description:

[0044] Embodiment 1:

[0045] In this embodiment, the provided breast surgery pressure bandage device comprises a wearing vest 1, a pressure mechanism 2, a balancing airbag 3 and a pressure regulating mechanism 4, wherein:

[0046] The wearing vest 1 is composed of a wrapping cloth 11, two shoulder straps 12 and an elastic member 13. The elastic member 13 is connected to both ends of the wrapping cloth 11, so that the size of the enclosed area of ​​the wrapping cloth 11 can be adjusted to adapt to the body shape of different patients, or to adjust the tightness of the wrapping. Both ends of the shoulder straps 12 are fixed on the same side of the wrapping cloth 11 to ensure that the wrapping cloth 11 is firmly worn. The wrapping cloth 11 is penetrated by two symmetrically arranged device ports 14, which correspond to the two breasts of the patient respectively. A device ring 15 is installed on the device port 14, and a protective cover 16 is installed on the device ring 15.

[0047] The pressurizing mechanism 2 includes two pressurizing air cushions 21, which are respectively installed on the opening sides of the two protective covers 16 and directly act on the breast area of ​​the patient;

[0048] The balancing airbag 3 is installed on the inner side of the wrapping cloth 11 and corresponds to the patient's abdomen, and can sense the fluctuation of the patient's abdomen when breathing;

[0049] The pressure regulating mechanism 4 is connected between the two pressurized air cushions 21 and the balancing air bag 3. The balancing air bag 3 changes the pressure of the two pressurized air cushions 21 through the pressure regulating mechanism 4 according to the patient's breathing action. Specifically, when the patient inhales, the abdomen and the thorax will expand, and the expansion of the abdomen squeezes the balancing air bag 3. The pressure of the pressurized air cushion 21 is reduced accordingly through the pressure regulating mechanism 4, thereby avoiding excessive squeezing of the breast; on the contrary, when the patient exhales, the abdomen and the thorax contract, the pressure in the balancing air bag 3 decreases, and the pressure regulating mechanism 4 increases the pressure of the pressurized air cushion 21 accordingly to maintain the relative balance of the air pressure inside the pressurized air cushion 21, thereby avoiding the patient's pressure being high and low due to the ups and downs of the thorax when breathing, which affects the recovery effect;

[0050] This design is very easy to operate. Medical staff only need to ensure that the device is worn correctly on the patient, and the device can automatically adjust the pressure according to the patient's breathing dynamics. Its beneficial effect is that it significantly improves the patient's comfort, reduces the labor intensity of medical staff, and helps promote wound healing and reduce postoperative complications. In addition, the design of the device takes into account the individual differences of patients and can adapt to patients of different body shapes. At the same time, it provides good breathability to ensure the comfort and safety of patients during postoperative recovery.

[0051] The pressure regulating mechanism 4 is a key component of the device. For details, please refer to Figure 2 and Figure 6 The pressure regulating mechanism 4 includes a three-way pipe 41, two connecting pipes 42, a regulating pipe 43 and a regulating member 44. The three-way pipe 41 is a core component of fluid distribution. Both ends of the three-way pipe 41 are respectively connected to the two connecting pipes 42 to ensure that the fluid can be effectively distributed. The other ends of the two connecting pipes 42 respectively penetrate the two protective covers 16 and are connected to the two pressurized air cushions 21. Such a design enables the pressurized air cushions 21 to receive the fluid pressure from the three-way pipe 41.

[0052] The regulating tube 43 is responsible for transmitting the pressure change of the balancing airbag 3 to the pressurized air cushion 21. Both ends of the regulating tube 43 are connected with connecting tubes 45. One connecting tube 45 is connected with the other end of the three-way tube 41, and the other connecting tube 45 passes through the wrapping cloth 11 and is connected with the balancing airbag 3, forming a closed fluid circuit. In this circuit, the regulating member 44 plays a vital role. It is movably installed inside the regulating tube 43 and can move freely. When the balancing airbag 3 is squeezed, it will drive the regulating member 44 to move inside the regulating tube 43, thereby changing the air pressure of the two pressurized air cushions 21.

[0053] This design cleverly utilizes the principle of mechanical fluid balance to adjust the pressure of the pressurized air cushion 21 by expanding and contracting the balancing air bag 3. When the patient inhales, the abdomen expands and squeezes the balancing air bag 3, causing the adjustment member 44 to move, thereby reducing the pressure of the pressurized air cushion 21; when the patient exhales, the abdomen contracts, the pressure of the balancing air bag 3 decreases, and the adjustment member 44 moves in the opposite direction, increasing the pressure of the pressurized air cushion 21. Such an automatic adjustment mechanism ensures that the pressurized air cushion 21 can adapt to the dynamic changes of the thorax during the patient's breathing, thereby providing a more comfortable and effective postoperative care method.

[0054] In further optimization, the design of the adjustment member 44 is refined, please refer to Figure 4 and Figure 8 The adjusting member 44 includes two piston plates 441 movably arranged inside the adjusting tube 43. The two piston plates 441 are arranged up and down. The outer sides of the piston plates 441 are in contact with the inner wall of the adjusting tube 43 to ensure good sealing and stability. Adjusting racks 442 are fixed on opposite sides of the two piston plates 441. The design of the adjusting racks 442 allows the relative movement between the piston plates 441 to be converted into pressure changes inside the adjusting tube 43. The adjusting member 44 also includes a mounting rod 443 connected to the inner wall of the adjusting tube 43. The mounting rod 443 is rotatably mounted with an adjusting gear 44 4. The two adjusting racks 442 are respectively meshed with the two opposite sides of the adjusting gear 444. Such a meshing mechanism enables the movement of the piston plate 441 to accurately control the rotation of the adjusting gear 444, thereby affecting the pressure of the pressurized air cushion 21. The regulating tube 43 is provided with a balancing air hole 431 located between the two piston plates 441. The function of the balancing air hole 431 is to balance the pressure inside the regulating tube 43, ensuring that the movement of the piston plate 441 is more stable and controllable. This sophisticated design not only improves the pressure regulation accuracy of the device, but also enhances its sensitivity in responding to changes in the patient's breathing.

[0055] In specific operations, Figure 2 , Figure 3 and Figure 4As shown in the figure, when the patient inhales, the abdomen will expand before the thorax, and the expansion of the abdomen will generate greater pressure to squeeze the balancing airbag 3. At this time, the air pressure inside the balancing airbag 3 increases, which will push the piston plate 441 located below to move upward. Under the action of the adjusting rack 442 and the adjusting gear 444, the upper piston plate 441 will descend, and the distance between the upper piston plate 441 and the pressurized air cushion 21 will increase, resulting in an increase in the volume sealed by the upper piston plate 441, the connecting pipe 45, the three-way pipe 41, the connecting pipe 42 and the pressurized air cushion 21, thereby reducing the air pressure of the pressurized air cushion 21. , the patient's chest will not be subjected to greater pressure when it expands, avoiding tissue damage caused by excessive squeezing; on the contrary, when the patient exhales, the abdomen and chest will shrink, and due to the different air pressures on the opposite sides of the two piston plates 441, the air pressure pushes the two piston plates 441 to move, that is, the upper piston plate 441 moves upward and the lower piston plate 441 moves downward to achieve air pressure balance. Due to the upward movement of the upper piston plate 441, the air pressure inside the pressurized air cushion 21 will increase, adapting to the reduction of the patient's chest, avoiding the risk of subcutaneous effusion and skin flap necrosis due to insufficient pressure.

[0056] Through this design, the adjustment member 44 can accurately respond to the pressure changes of the balancing airbag 3, and through the interaction between the piston plate 441 and the adjustment rack 442, and the rotation of the adjustment gear 444, the pressure of the pressurized air cushion 21 can be precisely controlled. This mechanism ensures that the device can automatically adjust the pressure according to the patient's breathing dynamics, thereby maximizing the patient's comfort while providing effective care.

[0057] Please note that Figure 4 A spring 445 is connected between the piston plate 441 located below and the end of the regulating tube 43 away from the three-way tube 41. The design of the spring 445 is crucial. It provides a restoring force for the piston plate 441, which helps to assist the piston plate 441 to return to the original position or the desired position when the patient exhales, that is, when the abdomen contracts and the pressure of the balance airbag 3 decreases;

[0058] The presence of the spring 1 445 ensures that the piston plate 441 can rebound quickly and stably during the exhalation phase after being squeezed by the balancing airbag 3, so that the upper piston plate 441 moves down accordingly, thereby increasing the internal pressure of the two pressurized air cushions 21. This auxiliary design not only improves the response speed and stability of the pressure regulation, but also ensures the cycle life and reliability of the entire system.

[0059] Through this design, the device can quickly and precisely adjust the pressure of the pressurized air cushion 21 during the patient's breathing cycle, maintaining smooth transitions and consistent comfort whether reducing pressure during inhalation or increasing pressure during exhalation. Such a mechanism is essential for providing high-quality postoperative care because it can adapt to the patient's changing needs while reducing the intervention of medical staff and ensuring the patient's comfort and safety during postoperative recovery.

[0060] Furthermore, in order to ensure that the vest 1 can be adapted to patients of different body shapes and to facilitate adjustment of tightness, the number of elastic members 13 is not less than one and is distributed in an array. The elastic member 13 includes a connecting belt 131, a connecting ring 132, a Velcro mother patch 133 and a Velcro child patch 134. One end of the connecting belt 131 is fixed to one end of the outer side of the wrapping cloth 11, the connecting ring 132 is fixed to the other end of the outer side of the wrapping cloth 11 and corresponds to the connecting belt 131, and the Velcro mother patch 133 is fixed to the outer side of the wrapping cloth 11. The Velcro sub-sticker 134 is fixed on the other end of the connecting belt 131 and corresponds to the connecting belt 131. With this design, medical staff can easily adjust the tightness of the wrapping cloth 11 by passing one end of the connecting belt 131 through the connecting ring 132 and bonding the Velcro sub-sticker 134 with the Velcro mother sticker 133, thereby ensuring that the wrapping cloth 11 can be firmly and comfortably wrapped around the patient's upper body. This adjustment method is not only fast and convenient, but also can accurately adapt to the patient's body contour and provide a personalized fit.

[0061] In addition, the design of the Velcro mother patch 133 and the Velcro sub-patch 134 allows for quick removal and adjustment, which is an important advantage for postoperative patients who need to frequently check their wounds or change dressings. At the same time, the array distribution of the elastic members 13 ensures uniform pressure distribution across the entire wrapping cloth 11, avoiding local over-tightening or over-loosening, and further improving the patient's comfort and wearing experience.

[0062] Embodiment 2:

[0063] In the second embodiment, in order to further improve the performance and adjustment accuracy of the postoperative breast compression bandage device, please refer to Figure 2 , Figure 6 and Fig.12 The balancing airbag 3 is connected to an inflation tube 31 that passes through the wrapping cloth 11. Two positioning rings 32 are fixed on the inner wall of the inflation tube 31. A clamping ball 33 is movably arranged between the two positioning rings 32. The diameter of the clamping ball 33 is larger than the inner diameter of the positioning ring 32 and smaller than the inner diameter of the inflation tube 31. Such a size design allows the clamping ball 33 to move freely between the positioning rings 32 while being kept inside the inflation tube 31.

[0064] A second spring 34 is connected between one of the positioning rings 32 close to the balancing airbag 3 and the card ball 33. The second spring 34 provides the card ball 33 with necessary elastic force, so that it can fit with the inner circumference of the other positioning ring 32, thereby maintaining the stability of the balancing airbag 3 when the patient breathes. Medical staff can use external inflation equipment to inflate or inhale air into the balancing airbag 3 through the inflation tube 31 to adjust the initial pressure of the two pressurized air cushions 21. The setting of the second spring 34 can make the card ball 33 fit with the inner circumference of the other positioning ring 32 when not inflated, and separate the two ends of the inflation tube 31 to prevent gas loss.

[0065] In addition, in order to ensure that the pressure of the pressurized air cushion 21 can be precisely controlled, a constant pressure tube 46 is connected between the two connecting tubes 45, and an adjustable valve component 47 is provided on the constant pressure tube 46. The valve component 47 allows medical staff to adjust the pressure according to the specific situation of the patient. By opening the valve component 47, under the connection of the constant pressure tube 46, the balancing air bag 3 is connected to the two pressurized air cushions 21. The medical staff inflates or deflates the interior of the balancing air bag 3 through the inflation tube 31, which can ensure that the pressure provided by the pressurized air cushion 21 is neither too large nor too small. By closing the valve component 47, the normal use of the device when worn can be guaranteed.

[0066] For details, please refer to Fig. 9 The valve member 47 includes a hemispherical body 471 which is rotatably mounted inside the constant pressure tube 46 and has the same inner diameter as the constant pressure tube 46. The existence of the hemispherical body 471 allows the flow path of the fluid to be physically blocked or opened, thereby controlling the pressure. A control rod 472 which is movable and passes through the constant pressure tube 46 is fixed on the hemispherical body 471. A control plate 473 is fixed on the control rod 472. By rotating the control plate 473 to drive the hemispherical body 471 to rotate, the two ends of the constant pressure tube 46 can be connected or blocked, thereby adjusting the air pressure of the pressurized air cushion 21 or performing normal work;

[0067] It should be noted that a screw 474 is movably inserted through the control board 473, a positioning block 461 is fixed on the outer side of the constant pressure tube 46, and a threaded positioning hole 462 is constructed on the positioning block 461. When one end of the screw 474 is threadedly inserted into the threaded positioning hole 462, the hemisphere 471 separates the two ends of the constant pressure tube 46. The design of the screw 474 and the positioning hole 462 can ensure the normal operation of the device and prevent the hemisphere 471 from rotating to connect the two ends of the constant pressure tube 46 when the device is working normally, thereby causing the device to lose its function.

[0068] Embodiment three:

[0069] In Example 3, in order to further optimize the patient's experience and improve the efficiency of postoperative care, please refer to Figure 2 and Figure 3The protective cover 16 and the pressurized air cushion 21 are both provided with drainage holes, and the two drainage holes correspond to each other, allowing liquid such as exudate or effusion to be drawn out from the inside of the pressurized air cushion 21, thereby providing an effective drainage path. Such a design helps to reduce postoperative fluid accumulation, reduce the risk of infection, and promote the drying and healing of the wound;

[0070] In addition, the protective cover 16 is also provided with a plurality of ventilation holes 17, which are designed to improve the comfort of the patient by allowing air circulation and reducing the accumulation of moisture and heat, so that the patient's skin can breathe better. This enhanced breathability helps to maintain the cleanliness and dryness of the wound area, while providing a cooler and more comfortable recovery environment.

[0071] Through these improvements, the device of Example 3 can not only provide the necessary pressure support, but also improve the patient's postoperative recovery conditions through the synergistic effect of the drainage holes and the air holes 17. These design considerations make the device more in line with clinical needs, while improving patient satisfaction and treatment effects.

[0072] Embodiment 4:

[0073] In the fourth embodiment, in order to provide more adjustment flexibility and meet the needs of different patients, the design of the connecting tube 42 is further optimized. Figure 5 , Figure 6 and Fig.10 The connecting pipe 42 is provided with an external thread on the outer peripheral side of the end away from the pressurized air cushion 21. Such a design allows the connecting pipe 42 to be detachably connected with other components. A retaining ring 411 is fixed on both ends of the three-way pipe 41. Connecting caps 412 are movably sleeved on both ends of the three-way pipe 41. The end of the connecting pipe 42 away from the pressurized air cushion 21 is threadedly inserted into the interior of the connecting cap 412, thereby forming a stable fluid connection.

[0074] In addition, in order to meet the needs of different patients for postoperative breast compression, the device design allows the removal of the pressurized air cushion 21 on either side as needed. When the pressurized air cushion 21 on one side is not needed, it can be removed and the corresponding sealing plug can be threadedly inserted into the inside of the connecting cap 412. This can effectively close the pipeline to prevent the outflow of gas and ensure that the pressurized air cushion 21 on the other side can work normally. For details, please refer to Fig.14 .

[0075] The outer peripheral side of the device ring 15 is constructed with external threads, and the open side of the protective cover 16 is threadedly sleeved on the device ring 15. This threaded connection method not only provides a stable fixing effect, but also allows quick disassembly and assembly, making it convenient for medical staff to adjust according to the specific situation of the patient.

[0076] Through these design improvements, the device of Example 4 provides higher adaptability and flexibility, allowing medical staff to make personalized adjustments based on the actual needs of the patient, while ensuring the stability and functionality of the device. These features make the device more in line with the needs of clinical applications and improve the efficiency and quality of postoperative care.

[0077] The operating method of the device in the present invention is:

[0078] First, the device ring 15 is installed on the device opening 14, and the protective cover 16 is fixed thereon. Subsequently, the pressurized air cushion 21 is installed on the opening side of the protective cover 16. The pressurized air cushion 21 will directly apply pressure to the breast. At the same time, the balancing air bag 3 is installed on the inner side of the wrapping cloth 11, corresponding to the patient's abdomen, so as to sense the rise and fall of the abdomen during breathing;

[0079] Next, the patient needs to be helped to put on the wearing vest 1, the shoulder straps 12 are adjusted to ensure a comfortable fit, and the tightness of the vest is fine-tuned through the elastic 13 to accommodate patients of different body shapes;

[0080] Subsequently, the pressure regulating mechanism 4 is correctly connected between the pressurized air cushion 21 and the balancing air bag 3, including the three-way pipe 41, the connecting pipe 42, the regulating pipe 43 and the regulating member 44, to ensure that the entire fluid circuit is unobstructed. After wearing, a comprehensive inspection is carried out to ensure that all components are installed in place, there is no risk of air leakage, and the patient feels comfortable. By opening the valve member 47 in the pressure regulating mechanism 4 and using an external inflation device to inflate or deflate the inflation tube 31, the pressure of the pressurized air cushion 21 is finely adjusted to meet the patient's comfort and treatment needs;

[0081] Once the wearing and adjustment are completed, the patient can start using the device, which will automatically adjust the pressure according to the patient's breathing dynamics. When the patient inhales, the abdomen expands to squeeze the balancing airbag 3, and the pressure of the pressurized air cushion 21 is reduced accordingly through the pressure regulating mechanism 4 to avoid excessive squeezing of the breast; when the patient exhales, the abdomen contracts, the pressure in the balancing airbag 3 decreases, and the pressure regulating mechanism 4 increases the pressure of the pressurized air cushion 21 to adapt to the reduction of the thorax. This automatic adjustment mechanism ensures that the pressurized air cushion 21 can adapt to the dynamic changes of the thorax during the patient's breathing, thereby providing a more comfortable and effective postoperative care method;

[0082] Throughout use, healthcare professionals should regularly monitor device pressure and patient comfort and make appropriate adjustments when necessary to ensure optimal patient care throughout the patient's recovery period.
