Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an electrically adjustable postoperative abdominal binder that can reduce pressure and prevent pressure sores. Background Technology

[0002] Currently, after laparotomy, the routine use of a regular abdominal binder combined with a saline bag for compression hemostasis is as follows. However, the traditional abdominal binder has a single fixation method, the adhesive area is not adjustable, and it is prone to upward movement, slippage, curling, and displacement, resulting in poor compression stability. The pressure of the saline bag is uncontrollable and uneven, which can easily lead to insufficient hemostasis or excessive local pressure, causing pain and skin ischemia. Moreover, the pressure of the existing abdominal binders cannot be monitored in real time, and medical staff can only rely on experience to judge, making it difficult to guarantee safety and effectiveness. When patients change from a supine to a semi-sitting / sitting position, the abdominal wall tension increases, and traditional pressure devices cannot release pressure quickly, which can easily pull on the incision and aggravate pain. In addition, drainage tube fixation devices are mostly rigid structures, while soft structures are not conducive to fixing drainage tubes, which can easily lead to instrument pressure ulcers in patients with low protein edema, malnutrition, or long-term bed rest. Therefore, it is necessary to develop and design an electrically adjustable postoperative abdominal binder that can reduce pressure and prevent pressure sores. Reducing pressure sores in patients while ensuring that drainage tubes are firmly fixed is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an electrically adjustable postoperative abdominal binder that can reduce pressure and prevent pressure sores, thereby reducing pressure sores in patients while ensuring the drainage tube is securely fixed.

[0004] To achieve the above objectives, the present invention provides the following solution: An electrically adjustable postoperative abdominal binder for pressure relief and pressure ulcer prevention includes an abdominal binder body and a flexible pressure-reducing structure disposed on the inner side of the abdominal binder body. The flexible pressure-reducing structure includes a clamping device for holding a drainage tube, flexible dispersing arms radiating outward in the circumferential direction of the clamping device, and an enlarged contact portion disposed at the end of the flexible dispersing arms away from the clamping device. At least three flexible dispersing arms are provided. The enlarged contact portion conforms to the body to avoid direct contact between the clamping device and the body.

[0005] Preferably, the clamping device includes a concave groove recessed on the abdominal binder body away from the body, a fixing clamp disposed in the concave groove, and an adjusting member connected to the fixing clamp for clamping or loosening the drainage tube, the adjusting member extending outward from the abdominal binder body.

[0006] Preferably, the fixing clamp includes a receiving groove formed on the inner wall of the concave groove, a spring disposed in the receiving groove, and a clamping block connected to the end of the spring. At least three springs are provided, and the clamping block is connected to the adjusting member.

[0007] Preferably, the system further includes a control system and an airbag disposed inside the abdominal binder body. A miniature electric air pump communicating with the airbag is disposed on the outside of the abdominal binder body, and the control system is electrically connected to the miniature electric air pump.

[0008] Preferably, at least two airbags are provided, and each airbag is connected to the miniature electric air pump via a separate pipe.

[0009] Preferably, the airbag is provided with a reserved slot, and a pressure sensor is installed in the reserved slot. The pressure sensor is electrically connected to the micro electric air pump and the control system.

[0010] Preferably, the reserved slot extends through the abdominal band body.

[0011] Preferably, the inner side of the abdominal binder is provided with a concave clearance space facing the body, the concave clearance space is recessed towards the side away from the body, and a replaceable absorbent liner is provided in the concave clearance space.

[0012] Preferably, the concave clearance space is attached to the replaceable absorbent liner via Velcro.

[0013] Preferably, the end of the abdominal binder body is provided with at least three connecting straps from top to bottom, and the connecting straps are connected to the end of the abdominal binder body away from the connecting strap.

[0014] The present invention achieves the following technical effects compared to the prior art: By incorporating a flexible decompression structure with a clamping device and at least three radiating flexible arms on the inner side of the abdominal binder, and by dispersing the support force of the clamping device to a larger area of ​​the body surface through an enlarged contact portion, the abdominal binder can not only securely clamp the drainage tube and prevent it from slipping or compressing local tissues, but also effectively prevent the clamping device from directly contacting the skin and forming a point-like high-pressure area, significantly reducing the risk of pressure injury (pressure sores). At the same time, the enlarged contact portion and the body-fitting design improve wearing comfort and fixation stability, making it especially suitable for patients who need to wear an abdominal binder for a long time after surgery and have drainage tubes.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The purpose of this invention is to provide an electrically adjustable postoperative abdominal binder that can reduce pressure and prevent pressure sores, thereby reducing pressure sores in patients while ensuring that the drainage tube is firmly fixed.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] refer to Figures 1-2The electrically adjustable postoperative abdominal binder for pressure relief and pressure ulcer prevention disclosed in this embodiment of the invention includes at least an abdominal binder body 1. A flexible pressure-reducing structure is provided on the inner side (i.e., the side closest to the body) of the abdominal binder body 1. The flexible pressure-reducing structure includes a clamping device 6 for holding a drainage tube. Flexible dispersing arms 5 are radiating outwards from the clamping device 6. An enlarged contact portion is provided at the end of the flexible dispersing arm 5 away from the clamping device 6. The surface area of ​​the enlarged contact portion is larger than the surface area of ​​the flexible dispersing arm 5. At least three flexible dispersing arms 5 are provided. The enlarged contact portion fits snugly against the body to prevent the clamping device 6 from directly contacting the body. The abdominal binder features a flexible pressure-reducing structure with a clamping device 6 and at least three radiating flexible dispersion arms 5 on the inner side of the binder body 1. By expanding the contact area, the supporting force of the clamping device 6 is distributed to a larger area of ​​the body surface. This not only securely clamps the drainage tube and prevents it from slipping or compressing local tissues, but also effectively prevents the clamping device 6 from directly contacting the skin and forming a point-like high-pressure area, significantly reducing the risk of pressure injury (pressure sores). At the same time, the design of the expanded contact area to fit the body improves wearing comfort and fixation stability, making it especially suitable for patients who need to wear an abdominal binder for a long time after surgery and have drainage tubes.

[0021] It should be noted that the flexible dispersing arm 5 and the expanded contact area are integrally molded from medical-grade ultra-thin soft silicone. The flexible dispersing arm 5 is designed with an octopus-like structure, preferably 6-8 in number, without hard edges or concentrated pressure points. It can utilize the elasticity of silicone and the biomimetic multi-arm design to evenly and disperse the local pressure at the clamping device 6 to a larger area of ​​the body surface. At the same time, the octopus-like structure can adaptively deform when conforming to the body's curves, avoiding the generation of shear forces or stress concentration points. The ultra-thin soft silicone material ensures soft contact with the skin, reduces friction damage, and facilitates cleaning and disinfection. It significantly improves the pressure relief and anti-pressure ulcer effect when fixing the drainage tube, enhances wearing comfort and compliance, and reduces the risk of postoperative complications caused by long-term compression or tube displacement. It can effectively prevent instrument-induced pressure ulcers in patients with low protein edema, malnutrition, obesity, and long-term bedridden patients.

[0022] In one implementation, hooks are provided on both sides of the end of the abdominal binder body 1 closest to the lower body. The hooks are located 3cm from the lower edge of the abdominal binder body 1, and a low-position drainage bag is hooked onto the hook. The low-position drainage bag is connected to the drainage tube. The hook is a medical-grade silicone one-piece molded elastic automatic closing type with an elastic cantilever buckle at the opening. After the drainage bag is hooked into the loop, it automatically springs back and locks. It can only be manually pried open and removed to prevent it from falling off. It has rounded corners and no sharp corners, so there is no risk of scratching. The hooks are connected to the abdominal binder by a 5cm wide elastic medical webbing. The abdominal binder body 1 has a storage slot corresponding to the position of the hook. When not in use, the hook is bent upward and inserted into the storage slot, which is firmly fixed and completely fits the abdominal binder without protruding outward. It does not press or scratch when lying flat in bed. When in use, it can be taken out from the slot and unfolded downward to hang the drainage bag, which is convenient for the patient to get out of bed and move around.

[0023] In one embodiment, the clamping device 6 includes a concave groove recessed on the abdominal binder body 1 towards the side away from the body. A fixing clip is disposed in the concave groove, and an adjusting member is connected to the fixing clip for clamping or loosening the drainage tube. The adjusting member extends outward from the abdominal binder body 1. When it is necessary to insert the drainage tube, the fixing clip is loosened by the adjusting member to form a space for the drainage tube to pass through. Then the drainage tube is inserted into the body. The clamping or loosening of the drainage tube can be operated directly from the outside without opening the abdominal binder or touching the patient's wound. This avoids the clamping mechanism and tube compressing the abdominal skin and reducing the risk of pressure sores. It also makes it easy for medical staff to quickly adjust the drainage status. At the same time, the concave design of the groove can accommodate and protect the drainage tube connector, preventing the tube from being accidentally bent or dislodged under pressure. This significantly improves the safety, convenience and patient comfort of postoperative drainage management.

[0024] It should be noted that the abdominal binder body 1 is equipped with a concealed slide for the flexible decompression structure to slide. A slider is mounted on the concealed slide, extending out of the abdominal binder body 1. The side of the slider closest to the body connects to the clamping device 6. Zipper structures are provided on the upper and lower sides of the slide for closing the slide and positioning the slider. The slider is physically locked and positioned by partially opening and closing the zippers, preventing unexpected displacement of the slider during patient movement or position changes. During clinical operation, simply open the corresponding section of the zipper to slide the slider to the corresponding position of the drainage tube outlet. Then close the slide and use the zipper teeth to clamp and limit the slider, eliminating the need for additional locking components. Simultaneously, the slider extends outward from the abdominal binder body 1, ensuring that the adjustment process does not touch the patient's body. This guarantees the accuracy and stability of the decompression structure positioning and avoids friction and irritation to the abdominal skin and drainage tube opening caused by repeated operations, significantly improving the ease of adjustment, positioning reliability, and overall pressure ulcer prevention effect of the postoperative abdominal binder.

[0025] In addition, concealed slides can be provided in both the longitudinal and transverse directions of the abdominal belt body 1, and at least three concealed slides are provided in both the transverse and longitudinal directions to ensure the range of movement of the flexible pressure relief structure.

[0026] It should be noted that the preferred abdominal binder 1 has 3 sets of main slides in both the horizontal and vertical directions, and an additional set of empty slides of the same specification is added next to the main slides to accommodate the fixing of newly added drainage pipes.

[0027] In one implementation, the fixing clip includes a receiving groove formed on the inner wall of the concave groove. A spring is installed in the receiving groove, and a clamping block is connected to the end of the spring. There are at least three springs and clamping blocks. The clamping blocks are connected to the adjusting component. The multiple sets of springs can automatically adjust the compression amount according to the diameter of the drainage tube and provide a uniform radial clamping force, avoiding excessive clamping at a single point, which may cause deformation of the drainage tube or obstruction of flow. It also prevents the tube from slipping due to insufficient clamping force. When it is necessary to loosen the tube, the clamping blocks are pulled open simultaneously by the adjusting component, so that the drainage tube can be taken out or its position adjusted without obstruction. Under the premise of ensuring the stable fixation of the drainage tube, the risk of local pressure damage to the tube wall is significantly reduced. Moreover, the multi-point clamping structure, combined with the concave layout of the concave groove, ensures that the clamping force is fully applied to the receiving groove on the outside of the abdominal binder body 1, avoiding any contact between the clamping mechanism and the patient's body, and further improving the safety and adjustment convenience of postoperative drainage management.

[0028] refer to Figure 2 As a preferred approach, it also includes a control system and an airbag 4 located inside the abdominal binder body 1. A miniature electric air pump connected to the airbag 4 is located on the outside of the abdominal binder body 1. The control system is electrically connected to the miniature electric air pump and can dynamically adjust the inflation and deflation pressure of the airbag 4 according to the patient's body shape, position and postoperative recovery stage. This applies uniform and controllable intermittent pressure loading to the abdominal area, actively promotes local blood circulation and reduces continuous pressure on tissues. Together with the octopus-like bionic arm with a flexible decompression structure, it forms a dual anti-pressure ulcer mechanism of "active pneumatic pressure regulation + passive elastic dispersion".

[0029] It should be noted that the mini electric air pump is preferably positioned on the left or right sides of the waist to avoid pressing on the wound and to facilitate operation.

[0030] refer to Figure 2 As a preferred approach, at least two airbags 4 are configured, and each airbag 4 is connected to a miniature electric air pump through a separate pipe. That is, each airbag 4 is individually controlled by the miniature electric air pump, and a gap is left between adjacent airbags 4, preferably 2mm-10mm. This achieves precise and zoned pressure management of the abdominal area. The control system can adjust the inflation and deflation of each airbag 4 differently according to the pressure requirements of different parts of the patient or the distribution of wounds, avoiding unnecessary pressure on specific areas (such as drainage tube outlets and surgical incisions) caused by uniform overall pressure. The gap between the airbags 4 serves as a natural airflow channel and pressure buffer, which is conducive to skin ventilation and heat dissipation, reduces the risk of maceration, and further eliminates the shear stress concentration points that may be generated at the edges of the airbags 4.

[0031] It should be noted that when the airbag 4 is set as a single piece, it covers the entire inner side of the abdominal binder body 1, and a clearance space is reserved for the use of the hidden slide and flexible pressure relief structure. At this time, the area of ​​the airbag 4 without clearance space is still connected. When there are at least two airbags 4, the hidden slide and flexible pressure relief structure are set in the gap between two adjacent airbags 4. When a single piece of airbag 4 is used, it covers the entire surface and precisely reserves clearance space for the track and flexible pressure relief structure, which not only maximizes the effective working area of ​​the airbag 4 and achieves uniform pressure loading of the entire abdomen, but also avoids physical interference with the sliding of the clamping device 6 and the movement of the drainage tube. The structure is simple and reliable. When at least two independently controlled airbags 4 are used, the hidden slide and flexible pressure relief structure are arranged in the 2mm-10mm gap between adjacent airbags 4, so that the pneumatic pressurization system and the mechanical fixing system are completely separated and interlocked in space. When the airbag 4 is inflated or deflated, it will not squeeze or pull the slider and clamping device 6, and the adjustment of the drainage tube fixing point is not affected by the pressure fluctuation of the airbag 4.

[0032] refer to Figure 1 As one implementation method, the airbag 4 is provided with a reserved slot, in which a pressure sensor is snapped in. The pressure sensor is electrically connected to the micro electric air pump and control system. The pressure sensor is installed in the reserved slot by snapping, which facilitates quick assembly, disassembly and disinfection before and after clinical use, and ensures the stable positioning of the sensor during the frequent deformation of the airbag 4, without compressing the patient's skin or affecting the flexible distribution of the airbag 4 itself.

[0033] It should be noted that the pressure sensor is a graphene sensor, which is closely attached to the inside of the airbag 4 to collect real-time data on the actual pressure applied at the incision site, with an accuracy of ≤0.3 kPa. A visual three-color indicator is installed on the outside of the abdominal band, and this indicator is electrically connected to the graphene sensor. Green indicates normal pressure, yellow indicates low pressure requiring inflation, and red indicates excessive pressure requiring depressurization. This allows for visual assessment of pressure safety and effectiveness without the need for instruments. The graphene sensor is only 0.1–0.5 mm thick, soft, and flexible, allowing it to closely conform to the contours of the airbag 4 and the abdominal wall without any hard protrusions, making it particularly suitable for… For patients with postoperative edema and thin skin, this abdominal binder improves wearing comfort and safety. The working pressure of the main body 1 is in the low-pressure clinical range of 2.0-4.5 kPa. The graphene sensor in this range has high sensitivity, high linearity and high resolution, which can achieve precise monitoring of pressure for hemostasis and incision tension reduction. Moreover, the graphene sensor can stably respond to pressure fluctuations caused by patient turning over, coughing and changes in body position, with stable and reliable readings, improving the system control accuracy. It achieves full-coverage silicone waterproof encapsulation, reaching IP67 waterproof rating, and is safe and non-irritating for long-term close-fitting use. The main body of the abdominal binder can be washed and reused for a long time, resulting in lower overall cost.

[0034] As one implementation method, a pre-reserved slot runs through the abdominal binder body 1, allowing operators to insert, remove, and repair electronic components without opening the inside of the abdominal binder or touching the patient's skin, significantly improving the convenience and hygiene safety of clinical use.

[0035] refer to Figure 2 As an implementation method, a concave avoidance space 7 is provided on the inner side of the abdominal binder facing the body. The concave avoidance space 7 is recessed away from the body. A replaceable absorbent liner 8 is provided in the concave avoidance space 7, which can effectively avoid direct physical pressure on the wound area by the abdominal binder and the air bag 4, reduce the risk of postoperative local pain and pressure injury, alleviate pain and prevent local ischemia. At the same time, the concave space provides a buffer and absorption area for exudate. The replaceable absorbent liner 8 can collect a small amount of fluid from the wound or drainage tube in time, keep the inner side of the abdominal binder and the skin of the body dry and clean, and reduce the chance of maceration and infection. When the liner is contaminated, there is no need to replace the entire abdominal binder. It is only necessary to remove it from the concave avoidance space 7 and replace it with a new replaceable absorbent liner 8. This not only saves medical costs, but also greatly improves the convenience of clinical care and patient comfort.

[0036] It should be noted that the inner liner is a sheet-like absorbent structure that is attached to the corresponding incision area on the inside of the groove avoidance space by local Velcro. When it needs to be replaced, the airbag 4 is adjusted to a non-pressurized state, and medical staff can reach in from the side or lower edge of the abdominal binder to directly tear off the old inner liner and attach the new inner liner. There is no need to unfasten the adhesive fixation wings, loosen the abdominal binder, or adjust the drainage tube, and the original compression positioning and fixation effect is not affected.

[0037] The miniature air pump, control system, wiring and pressure sensor interface are all fully enclosed in waterproof potting to achieve IP67 waterproof rating. The airbag 4 is sealed to the main body, and the whole thing can be gently hand-washed and reused. It is waterproof and washable.

[0038] refer to Figure 2 As an implementation method, the concave clearance space 7 and the replaceable absorbent liner 8 are attached with Velcro, which enables the liner to be quickly, firmly and repeatedly removed and fixed to the abdominal binder body 1. During clinical operation, the liner only needs to be aligned with the concave space and pressed lightly to complete the installation. When changing, there is no need to remove the entire abdominal binder or turn the patient's body over significantly, which significantly improves nursing efficiency. At the same time, the Velcro connection method can prevent the liner from shifting, curling or slipping when the patient moves or changes position, ensuring that the absorbent area is always facing the wound or drainage tube outlet, avoiding local pressure or failure of exudate collection caused by liner misalignment.

[0039] As one implementation method, the end of the abdominal binder body 1 is provided with at least three connecting straps 3 from top to bottom. The connecting straps 3 are connected to the end of the abdominal binder body 1 away from the connecting straps 3, realizing personalized pressure adjustment and gradual tightening of different areas of the upper, middle and lower abdomen. In clinical use, medical staff can adjust the tightness of each connecting strap 3 according to the patient's body shape (such as the difference in circumference of the lower rib, waist circumference and upper edge of the pelvis), wound location and drainage tube outlet distribution, so as to avoid the "tight at the top and loose at the bottom" or local overpressure phenomenon caused by traditional single or double abdominal binders. At the same time, the multi-segment connecting strap 3 structure can also effectively isolate the tension transmission caused by changes in the patient's body position or abdominal movement, and prevent single-point traction from affecting the pressure distribution of the airbag 4 or the stability of the clamping device 6.

[0040] It should be noted that the connecting strap 3 can be provided with a hook and loop surface, and the end of the abdominal belt body 1 away from the connecting strap 3 is provided with a hook and loop pointed surface to achieve tightening of the abdominal belt body 1.

[0041] refer to Figure 1 In one implementation, the connecting strap 3 includes an upper adhesive wing, a middle adhesive wing, and a lower adhesive wing, and is attached to the abdominal binder body 1 by a fixing strap 2. The end of the abdominal binder body 1 away from the connecting strap 3 is also provided with a fixing strap 2, with the Velcro tip attached to the fixing strap 2. The fixing strap 2 serves as an intermediate carrier, enhancing the connection strength between the adhesive wing and the abdominal binder body 1, preventing the fabric of the abdominal binder body 1 from pilling or deforming due to repeated tearing and pasting, and also concentrating the stress of the entire connection system in the area of ​​the fixing strap 2 when under force, effectively protecting the structural integrity of the abdominal binder body 1. The upper adhesive wing is fixed to the upper abdominal area under the ribs to prevent the abdominal binder from shifting upwards. The middle adhesive wing is located in the main fixation area to provide basic pre-tension force for the waist. The lower adhesive wing is fixed above the iliac crest to prevent the abdominal binder from slipping and curling.

[0042] Alternatively, connecting strap 3 and fixing strap 2 can be connected without Velcro. Wearing method: The patient lies flat, and the abdominal binder body 1 can be directly inserted and laid under the patient's waist. After aligning it with the incision in the center, the adhesive wings on both sides are pulled up and glued to fix it. The patient does not need to turn over, sit up or move around much. Wearing is quick and the positioning is accurate.

[0043] The control system of this invention includes a four-level electric inflation and pressure adjustment system, and a waterproof button panel is provided on the outside of the abdominal belt body 1, which has four pressure modes and a one-button deflation button. 0 gear (no pressure gear) The airbag 4 is completely deflated, leaving only the adhesive fixation, which facilitates incision observation, dressing changes, liner replacement, and turning over for nursing care; when the patient is in a semi-sitting / sitting position, switch to position 0 to eliminate abdominal wall pressure, reduce incision tension, and alleviate pain.

[0044] Level 1 (Low pressure relief setting 2.0~2.5kPa) This product is suitable for patients in the early postoperative period who are sensitive to pain, have minimal bleeding, and experience low-protein edema.

[0045] Level II (Standard blood pressure control: 3.0–3.5 kPa) Standard postoperative compression setting.

[0046] Level III (Extreme Compression 4.0–4.5 kPa) Use briefly when there is excessive bleeding and stronger hemostasis is needed.

[0047] Operating mode: Press the target setting → the micro air pump automatically inflates → the graphene sensor monitors in real time → the pump automatically stops when the preset pressure is reached; when the pressure drops slowly, the system automatically replenishes a small amount of air to achieve constant pressure stabilization.

[0048] Postoperative full-cycle usage mode This abdominal binder can cover the entire postoperative care period after open surgery, and its functions can be automatically switched according to the healing stage: Within 1 week after surgery (compression hemostasis period) The pressure is maintained at level II standard pressure for continuous application, with the core function of compression to stop bleeding at the incision site and reduce tissue edema. When the patient is in a semi-sitting position, eating, or coughing up phlegm, the pressure is switched to level 0 to release pressure and reduce tension. Pressure is restored when the patient lies flat.

[0049] Postoperative period 1–4 weeks (incision healing period) The bleeding from the incision has basically stopped. The pressure of the airbag 4 is switched to level I or level II for low-intensity support to reduce abdominal wall tension and relieve pain during activity. It still needs to be worn for 24 hours.

[0050] Postoperative period 1-3 months (abdominal wall tension reduction and protection period) It does not require continuous inflation and compression, and mainly provides fixed protection at level 0; when getting out of bed, coughing, or exerting force, it can be briefly switched to level I / II to provide support, prevent incisional hernia, and improve long-term wearing comfort.

[0051] Clinical wearing period: For open abdominal surgery with a 30cm incision, to ensure fascial healing and prevent incision dehiscence and incisional hernia, it is recommended to wear an abdominal binder continuously for 3 months. High-risk individuals can extend this period to 3-6 months.

[0052] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
