Description

Technical Field

[0001] This invention relates to the field of hip compression technology, and more particularly to an angled fixation hip compression bandage device. Background Technology

[0002] A hip compression bandage is a medical device that covers and protects a hip wound, controls bleeding, reduces swelling, and immobilizes the affected area by applying appropriate pressure.

[0003] In existing technologies, hip compression bandages typically consist of a base, an abdominal patch, a perineal patch, and a leg flap. During use, the base is placed over the patient's waist, and the leg flap is placed over the patient's legs. The base and leg flap are generally connected using Velcro. While Velcro offers the convenience of quick bonding, its material properties limit its lifespan. This is because the hook-like structure is prone to irreversible deformation or even breakage due to metal fatigue during repeated bending and pulling. The fibers on the surface also shed due to long-term friction, leading to a significant decrease in adhesive strength. This is especially problematic in high-frequency use scenarios where the bandage may loosen or even detach. Furthermore, when adjusting the pressure applied to the hip, existing designs require repeatedly pulling the base and leg flap and re-attaching the Velcro. This process is not only cumbersome and inefficient, but also makes precise pressure control difficult. More seriously, frequent mechanical pulling accelerates the wear of the Velcro hook structure, further shortening its lifespan.

[0004] Therefore, an angle-fixed hip compression bandage device needs to be designed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an angled fixation hip compression bandage device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An angular fixation hip compression bandaging device includes a waist bandage, a connecting strap, and two leg bandages. The two ends of the waist bandage are connected by a connecting assembly, which includes a first mounting frame, a first strap, and a second strap. The first mounting frame is fixed to one end of the waist bandage, and the first strap is fixed to the other end of the waist bandage. The first strap and the second strap are connected by an adjustment structure. Several hooks are fixed on both sides of the first strap, and two hanging rings are fixed on the end of the second strap away from the first strap.

[0007] As a preferred embodiment of the present invention, the hooks are arranged in pairs, and the multiple groups of hooks on the same side are arranged in a linear array.

[0008] As a preferred embodiment of the present invention, the adjustment structure includes a second mounting frame, which is fixed to the end of the first strap away from the waist bandage. A rotating shaft is rotatably mounted on the second mounting frame. A hole is provided at the top of the second mounting frame, through which the rotating shaft passes and is rotatably mounted. A fixing block is fixed at the top of the rotating shaft. A winding wheel is fixedly sleeved on the rotating shaft and connected to the end of the second strap. A locking ring is fixed on the second mounting frame. The locking ring has a plurality of first teeth. A movable cap is provided above the locking ring. The cap has a plurality of second teeth and a groove. The fixing block slides in the groove.

[0009] As a preferred embodiment of the present invention, both the fixing block and the groove have rectangular cross-sections, and the side of the fixing block fits against the groove wall.

[0010] As a preferred embodiment of the present invention, the waist bandage and the connecting belt are provided with an auxiliary pressure structure. The auxiliary pressure structure includes a sheet-shaped pressure bladder and several strip-shaped pressure bladders. The sheet-shaped pressure bladder is arranged on one side of the waist bandage, and the several strip-shaped pressure bladders are arranged on the other side of the waist bandage. Adjacent strip-shaped pressure bladders are connected by a connecting tube.

[0011] As a preferred embodiment of the present invention, the auxiliary pressurization structure further includes a three-way valve, which has one input end and two output ends. A first hose is connected to the sheet-shaped pressurization bladder, and a second hose is connected to one of the strip-shaped pressurization bladders. The two output ends of the three-way valve are respectively connected to the first hose and the second hose, and the input end of the three-way valve is connected to an air supply pipe.

[0012] As a preferred embodiment of the present invention, the side of the connecting strip is fixed with an adhesive female surface, and the back of each strip-shaped pressure bladder is fixed with an adhesive female surface.

[0013] As a preferred embodiment of the present invention, the rotating shaft, winding wheel, locking ring and rotating cap are arranged coaxially.

[0014] As a preferred embodiment of the present invention, the connecting strap is fixed at the middle of the waist bandage, and the two leg bandages are respectively fixed on both sides of the connecting strap, with each leg bandage being inclined.

[0015] As a preferred embodiment of the present invention, the gas supply pipe is provided with a pipe cap or a spring clamp.

[0016] The present invention has the following beneficial effects: 1. Replacing the traditional bandage connection structure, the adjustment process does not require disassembling the bandage or repeatedly gluing it. The mechanical locking structure has higher durability than Velcro, completely solving the problem of adhesion failure caused by Velcro wear in traditional designs and extending the service life of the bandage. 2. The pressure of the bandage can be precisely adjusted through the adjustable structure, making it convenient for patients to use. 3. The auxiliary compression structure includes a sheet-shaped compression bladder and several strip-shaped compression bladders. The sheet-shaped compression bladder can apply overall pressure to the patient's hip, which is suitable for extensive compression hemostasis in the early postoperative period. It can expand the pressure distribution area, improve the compression effect, and reduce the risk of local pressure sores. The strip-shaped compression bladders can apply precise pressure to local areas of the patient's hip. The patient can inflate the corresponding area of ​​the bladder according to the location of the injury, which can improve the targeting of treatment and avoid ineffective compression of healthy tissue. 4. The side of the connecting strap is fixed to the adhesive mother surface, and the back of the strip-shaped pressure bag is fixed to the adhesive daughter surface. The patient can attach the strip-shaped pressure bag to the adhesive mother surface to achieve quick fixation and flexible position adjustment. This breaks through the limitations of the traditional bandage's preset pressure area and is suitable for scenarios with irregular injury locations or where multiple areas need to be compressed together.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-8 An angular fixation hip compression bandage device includes a lumbar bandage 11, a connecting band 12, and two leg bandages 13. The connecting band 12 is fixed in the middle of the lumbar bandage 11, and the two leg bandages 13 are fixed on both sides of the connecting bandage 12. In use, the patient wraps the lumbar bandage 11 around the waist and wraps the two leg bandages 13 around one of the legs. By pulling at an angle, the two leg bandages 13 are wrapped around the hip and leg and cross each other to form an X-shaped connection structure. At this time, the lumbar bandage 11 and the connecting band 12 can jointly apply appropriate pressure to the hip, which helps to reduce wound bleeding, fix the dressing, prevent loosening, and reduce the risk of infection. The two leg bandages 13 are set at an angle relative to the lumbar bandage 11. By fixing the leg bandages 13 at a specific angle, the movement of the hip joint can be better restricted, pain and swelling can be reduced, healing can be promoted, and angular fixation of the patient's hip can be achieved. The two ends of the lumbar bandage 11 are connected by a connecting assembly, which includes a first mounting frame 21, a first strap 22, and a second strap 23. The first mounting frame 21 is fixed to one end of the lumbar bandage 11, and the first strap 22 is fixed to the other end. The first strap 22 and the second strap 23 are connected by an adjustment structure. After the bandage is worn, the adjustment structure is used to adjust the pressure applied by the lumbar bandage 11 and the connecting strap 12 to the patient's hip. Several hooks 221 are fixed on both sides of the first strap 22. The hooks 221 are arranged in pairs, and the multiple sets of hooks 221 on the same side are arranged in a linear array. Two hanging loops 231 are fixed to the end of the second strap 23 away from the first strap 22. Figure 1 and Figure 2As shown, when wearing the lumbar bandage 11, the patient first wraps the lumbar bandage 11 around the waist, then passes the second strap 23 and the adjustment structure through the first mounting frame 21 until the first strap 22 wraps around the first mounting frame 21. Then, the two hanging loops 231 are hooked onto one of the hooks 221. At this time, the lumbar bandage 11, the first strap 22 and the second strap 23 together form a ring structure and are tied around the patient's waist. Furthermore, the patient can hang the hanging loops 231 on the hooks 221 at different positions according to their own needs, thereby adjusting the tightness of the lumbar bandage 11. The adjustment structure includes a second mounting frame 31, which is fixed to the end of the first strap 22 away from the waist wrapping strap 11. A rotating shaft 32 is rotatably mounted on the second mounting frame 31. A hole is provided at the top of the second mounting frame 31, through which the rotating shaft 32 passes and is rotatably mounted. A fixing block 321 is fixed at the top of the rotating shaft 32. A winding wheel 33 is fixedly sleeved on the rotating shaft 32 and connected to the end of the second strap 23. When the winding wheel 33 rotates, it can wind or release the second strap 23. A locking ring 34 is fixed on the second mounting frame 31. The locking ring 34 is provided with several first teeth 341. A movable cap 35 is provided above the locking ring 34. The cap 35 is provided with several second teeth 352. In the initial state, as shown... Figure 6 As shown, several first teeth 341 and several second teeth 352 are in a meshing state. The swivel cap 35 has a groove 351. The fixing block 321 slides in the groove 351. The cross-section of the fixing block 321 and the groove 351 are both rectangular. The purpose is to enable the rotating shaft 32 to rotate through the fixing block 321 when the swivel cap 35 rotates. The swivel cap 35 is connected to the second mounting frame 31 by a spring 36. The spring 36 makes the swivel cap 35 always tend to move closer to the second mounting frame 31. In use, the patient can hang the two loops 231 on one of the hooks 221, and then precisely adjust the tightness of the lumbar bandage 11 through the adjustment structure, thereby precisely adjusting the pressure applied to the hip by the bandage. Specifically, in the initial state, under the elastic force of the spring 36, several second teeth 352 on the rotating cap 35 and several first teeth 341 on the locking ring 34 are in a mutually meshing state. At this time, the locking ring 34 provides a constraint for the rotating cap 35, and the rotating cap 35 cannot rotate. When restrained, the rotating shaft 32 and the winding wheel 33 cannot rotate. In this case, when the patient pulls the second strap 23, the second strap 23 can directly pull the first strap 22 through the winding wheel 33 and the second mounting frame 31, facilitating the initial connection, i.e., the connection between the hanging ring 231 and the hook 221. When pressure adjustment is required, the patient first pulls up the rotating cap 35, causing the rotating cap 35 to move until the rotating cap 35 separates from the locking ring 34. After the two separate, the locking ring 34 no longer provides pressure to the rotating cap 35. Under the constraint effect, the cap 35 can rotate freely. Then, the patient rotates the cap 35. Since both the groove 351 and the fixing block 321 have rectangular cross-sections, and the groove wall of the groove 351 is in contact with the side of the fixing block 321, the rotation of the cap 35 can drive the fixing block 321 to rotate. When the fixing block 321 rotates, the rotating shaft 32 rotates accordingly. During the rotation of the rotating shaft 32, the winding wheel 33 performs the winding and releasing action on the second belt 23. It can be understood that when the winding wheel 33 winds up the second belt... When the second belt 23 is in place, the pressure applied by the waist bandage 11 to the patient's hip increases. Conversely, when the winding wheel 33 releases the second belt 23, the pressure applied by the waist bandage 11 to the patient's hip decreases. After adjustment, the patient releases the cap 35, allowing the cap 35 to return to its original position under the action of the spring 36, until several first teeth 341 and several second teeth 352 engage again. At this point, the position of the cap 35 is fixed, the shaft 32 and the winding wheel 33 cannot rotate, and the second belt 23 is also fixed. It is worth noting that when the swivel cap 35 separates from the locking ring 34, the top of the fixing block 321 is still located in the groove 351, which allows the swivel cap 35 to smoothly drive the fixing block 321 to rotate. In summary, the hip compression bandage proposed in this invention replaces the connection structure of traditional bandages. The adjustment process does not require disassembling the bandage or repeatedly attaching it. The mechanical locking structure has higher durability than Velcro, completely solving the problem of adhesion failure caused by Velcro wear in traditional designs and extending the service life of the bandage. Furthermore, based on a stable connection, the pressure of the bandage can be precisely adjusted by adjusting the structure, which is convenient for patients to use. The waist bandage 11 and the connecting strap 12 are both equipped with an auxiliary pressure structure. This auxiliary pressure structure includes a sheet-like pressure bladder 41 and several strip-like pressure bladders 43. The sheet-like pressure bladder 41 is positioned on one side of the waist bandage 11, and the strip-like pressure bladders 43 are positioned on the other side of the waist bandage 11, forming a structure as follows: Figure 1 and Figure 2 As shown, the sheet-shaped pressure bladder 41 has a sheet-like structure and a large area, which can apply pressure to the entire hip of the patient. The strip-shaped pressure bladder 43 has a long strip-like structure, which can apply pressure to a local area of ​​the hip of the patient. The sheet-shaped pressure bladder 41 is connected to a first flexible tube 411. Adjacent strip-shaped pressure bladders 43 are connected to each other through a connecting tube 432. One of the strip-shaped pressure bladders 43 is connected to a second flexible tube 433. The auxiliary pressure structure also includes a three-way valve 44, which has one input end and two output ends. The two output ends of the three-way valve 44 are connected to the first flexible tube 411 and the second flexible tube 433, respectively. The input end of the three-way valve 44 is connected to an air supply tube 441. The end of the air supply tube 441 away from the three-way valve 44 is provided with a tube cap, which is used to block the air supply tube 441. The hip compression bandage proposed in this invention also has an auxiliary compression function. Specifically, after wearing the bandage, the patient can use an inflatable handbag to supply air into the sheet-like compression bladder 41 or several strip-like compression bladders 43. When the sheet-like compression bladder 41 is inflated, its overall expansion characteristics can evenly cover a large area of ​​the hip, forming a three-dimensional compression surface. This is particularly suitable for scenarios requiring extensive compression for hemostasis in the early postoperative period. By expanding the pressure distribution area, it effectively disperses the force per unit area, improving the compression effect and reducing the risk of pressure sores caused by excessive pressure on the local skin. The independent inflation design of the strip-like compression bladders 43 enables precise pressure application. The patient can selectively inflate the corresponding area of ​​the strip-like bladder according to the specific location of the hip injury (such as greater trochanteric contusion, anterior superior iliac spine hematoma, etc.), concentrating the pressure on the lesion site. This compression mode not only improves the targeting of treatment but also avoids ineffective compression of healthy tissues, especially... Suitable for complex injuries or cases with significant postoperative local exudation. More importantly, the combination of sheet-like and strip-like pressure bladders 43 forms a "whole + local" pressure system. Patients can first establish a basic pressure environment through the sheet-like bladder, and then dynamically adjust the inflation volume of the strip-like bladder according to the recovery process or symptom changes to achieve a pressure gradient distribution. For example, in the early postoperative period, high-pressure sheet-like bladders are used to control bleeding, in the middle period, partial decompression of the strip-like bladders is used to promote circulation, and in the later period, local compression is strengthened for residual swelling areas. This phased and differentiated pressure management strategy significantly improves rehabilitation efficiency. It should be noted that patients can flexibly choose between whole-body compression or specific compression by wearing the lumbar bandage 11 in the forward or reverse direction. In the connecting component, the second strap 23 is provided with several hooks 221 on both the front and back. Whether worn in the forward or reverse direction, patients can use the hooks 221 and the hanging rings 231 to quickly fix the lumbar bandage. The side of the connecting band 12 is fixed with an adhesive mother surface 42, and the back of each strip-shaped pressure bladder 43 is fixed with an adhesive daughter surface 431. When in use, the patient can directly attach the strip-shaped pressure bladder 43 to the adhesive mother surface 42. The adhesive daughter surface 431 and the adhesive mother surface 42 are used to achieve quick fixation and flexible position adjustment of the strip-shaped pressure bladder 43. The patient can freely attach the strip-shaped pressure bladder 43 to the adhesive mother surface 42 of any area of ​​the connecting band 12 according to the specific location of the hip injury or the postoperative rehabilitation needs. This fixation method breaks through the limitation of the traditional bandage with a preset pressure area. It is especially suitable for scenarios where the injury location is irregular or multiple areas need to be compressed simultaneously. For example, after hip replacement surgery, when the greater trochanter of the femur and the anterior superior iliac spine need to be compressed at the same time, the patient can position multiple strip-shaped pressure bladders 43 to the target area respectively to form multi-point precise compression. When the injury range expands or the position changes, it is only necessary to tear off the original bladder and re-attach it. There is no need to replace the entire bandage, which significantly improves the flexibility of treatment. Regarding air supply, the air path is controlled via a three-way valve 44. When air needs to be supplied to the sheet-shaped pressure bladder 41, the patient rotates the adjusting knob of the three-way valve 44 to connect the air supply tube 441 to the first flexible tube 411. When air needs to be supplied to several strip-shaped pressure bladders 43, the patient rotates the adjusting knob of the three-way valve 44 to connect the air supply tube 441 to the second flexible tube 433. Adjacent strip-shaped pressure bladders 43 are connected by a connecting tube 432. Therefore, during inflation, each strip-shaped pressure bladder 43 can inflate. After inflation, the patient screws the cap onto the air supply tube 441 to seal it and prevent gas leakage. It is worth mentioning that, to ensure the comfort of wearing the bandage, the three-way valve 44 can be integrated into the edge area of ​​the bandage, such as the end or side concealed position, away from the main pressure surface of the hip, to avoid valve leakage. The three-way valve 44 is directly in contact with the skin or protruding bone areas. The bandage itself has a multi-layered structure (such as an inner soft padding and an outer elastic bandage) that wraps around the valve, reducing pressure on the skin through physical isolation. Secondly, the three-way valve 44 features a flattened design, using a miniature three-way valve 44 with a thickness of less than 5mm, and its surface treatment process is optimized to ensure smooth, rounded edges, preventing stinging or abrasions from friction with the skin during activity. Furthermore, a silicone pad is added to the skin-contacting surface of the three-way valve 44, utilizing the flexibility and breathability of silicone to disperse local pressure and absorb vibrations during activity. For air connection, an embedded flexible tube connects the three-way valve 44 to the pressure bladder. The tube runs along the inside of the bandage and is fixed to avoid pressure from exposed tubing during wear, and the tube diameter is controlled within 2-3mm to reduce volume.

[0021] The specific working principle of this invention is as follows: The angular fixation hip compression bandaging device proposed in this invention achieves precise treatment and comfortable wear for hip injuries through a multi-module collaborative design. Its core structure consists of a lumbar bandage 11, a connecting strap 12, and two leg bandages 13. When worn, the lumbar bandage 11 wraps around the waist, and the two leg bandages 13 are diagonally pulled around the hip and cross to form an X-shaped fixation. This reduces wound bleeding and secures the dressing through the combined pressure of the lumbar region and the connecting strap 12, while the angular fixation of the leg bandages 13 restricts hip joint movement, relieving pain and swelling. The connecting component employs a design with a first strap 22 and a second strap 23 for adjustment. The patient then... The second strap 23's loops 231 can be hooked into the hooks 221 at different positions of the first strap 22 for initial fixation. During adjustment, pulling up the cap 35 separates the second tooth 352 from the first tooth 341 of the locking ring 34. Rotating the cap 35 drives the fixing block 321, the rotating shaft 32, and the winding wheel 33 to rotate through the rectangular groove 351, thereby achieving the winding or releasing of the second strap 23, and thus precisely adjusting the pressure of the waist bandage 11 on the hip. After adjustment, the cap 35 is released, and the spring 36 drives the cap 35 to reset, causing the teeth to re-engage and completing the mechanical locking. This design avoids the problem of easy wear and failure of traditional Velcro and extends its service life. The auxiliary compression structure achieves "overall + local" compression through the combination of sheet-shaped compression bladder 41 and strip-shaped compression bladder 43: the sheet-shaped compression bladder 41 is placed on one side of the lumbar bandage 11, and after inflation, it can evenly cover a large area of ​​the hip, suitable for extensive compression hemostasis in the early postoperative period; the strip-shaped compression bladder 43 is placed on the other side, and is quickly fixed to the side of the connecting band 12 by the adhesive sub-face 431 and the adhesive mother face 42. The patient can flexibly adjust the position of the strip-shaped bladder according to the location of the injury to achieve precise local compression and avoid compression of healthy tissue. Moreover, the strip-shaped compression bladders 43 are interconnected through the connecting tube 432, so only one needs to be compressed. Inflation is synchronous. When in use, the patient turns the three-way valve 44 to adjust the knob to switch the connection between the air supply tube 441 and the first hose 411 (sheet-shaped pressure bag 41) or the second hose 433 (strip-shaped pressure bag 43). After inflation, tighten the cap to seal the air supply tube 441 to prevent air leakage. In addition, the waist bandage 11 supports wearing in either the front or back. The second strap 23 has hooks 221 on both the front and back to ensure quick fixation in both wearing methods. Through structural innovation and detail optimization, the overall solution achieves stable fixation of the hip, precise pressure and dynamic adjustment, while improving wearing comfort and treatment flexibility.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
