Description

Technical Field

[0001] This utility model relates to a pressure fixation device, specifically a pressure device for wound treatment after brachial plexus decompression surgery. Background Technology

[0002] Applying pressure to the wound after brachial plexus decompression has several benefits, primarily in the following aspects:

[0003] 1. Pressure hemostasis: Postoperative pressure bandaging can increase local pressure, causing some small blood vessels to close, reducing the risk of further bleeding, and helping to stop the bleeding of the wound quickly.

[0004] 2. Promotes healing: Appropriate pressure can promote local blood circulation, accelerate the wound healing process, and reduce the risk of tissue necrosis.

[0005] 3. Prevention of hypertrophic scars: Continuous pressure can cause local capillaries to shrink and decrease in number, and endothelial cells to break down, resulting in local ischemia and hypoxia in the scar tissue. This ischemic and hypoxic state can inhibit the production of collagen fibers, accelerate the degradation of collagen fibers, and cause the collagen fiber structure to reorganize and arrange in parallel, thereby inhibiting scar hyperplasia and promoting scar maturation.

[0006] 4. Control edema: Pressurization can promote the return of blood and lymph fluid, increase the hydrostatic pressure of tissue fluid in the extravascular and extra-lymphatic interstitial space, thereby overcoming the effects of capillary pressure and interstitial colloid osmotic pressure, limiting the entry of fluid into the interstitial space, and reducing edema symptoms.

[0007] 5. Prevention of deep vein thrombosis: For patients who require long-term bed rest after surgery, compression therapy can prevent the formation of deep vein thrombosis in the lower extremities, a serious complication. By increasing venous return and reducing venous pressure, thrombus formation can be effectively prevented.

[0008] 6. Promotes limb reshaping: Appropriate pressure can limit tissue swelling, proliferation, and deformation, thereby helping to improve appearance and promote reshaping of the amputation stump (if necessary), which is highly beneficial for the fitting and use of prostheses. Although brachial plexus decompression does not involve amputation, pressure therapy still plays a role in promoting postoperative site reshaping.

[0009] 7. Prevention of joint contractures: By effectively controlling scar hyperplasia, pressure therapy can prevent and treat joint contractures and deformities caused by hypertrophic scars, helping to maintain normal joint function.

[0010] Currently, the main method for applying pressure to the wound after brachial plexus decompression surgery is to use bandages, etc., and to use appropriate pads or sandbags for pressure fixation. However, this simple bandaging fixation cannot adjust the pressure and tightness according to the subsequent wound condition. In addition, re-bandaging is time-consuming and laborious, making it very inconvenient to use. Utility Model Content

[0011] To address the aforementioned problems, the purpose of this invention is to provide a wound pressure device for brachial plexus decompression surgery.

[0012] To achieve the above objectives, the technical solution of this utility model is as follows: a pressure device for wound after brachial plexus decompression surgery, comprising a tile-shaped shoulder pad and a fixing strap for the shoulder pad, wherein the inner side of the shoulder pad is provided with plate-shaped external air cushions at the front and back respectively, and the shoulder contact side of each external air cushion is provided with plate-shaped internal air cushions at the top and bottom respectively, and the internal air cushions are all smaller than the external air cushions. Each external air cushion and internal air cushion is connected to the corresponding air outlet of an external electromagnetic valve through an inflation hose.

[0013] Furthermore, the outer side of the shoulder panel is covered with an outer shaping plate located at the bending part of the shoulder panel, and the interior of the outer shaping plate is filled with an arc-shaped plastic plate for shaping.

[0014] Furthermore, the outer side of the fixing strap is provided with a Velcro female buckle surface, the fixing end of the fixing strap passes through the pull buckle of the shoulder panel, and the inner side of the fixing end of the fixing strap is provided with a barb structure for fastening to the Velcro female buckle surface.

[0015] Furthermore, both the outer and inner air cushions are made of silicone.

[0016] Furthermore, the upper and lower outer sides of the shoulder panel are respectively provided with Velcro fasteners, and the front and back of the outer shaping plate are fixedly connected to the outer side of the shoulder panel by Velcro fasteners.

[0017] Furthermore, the shoulder panels are made of nylon fabric.

[0018] Furthermore, the lower part of the shoulder panel covering the arm is equipped with an arm strap secured by a Velcro closure.

[0019] This invention features an outer air-filled pad on the inner side of the shoulder pad, with a second, separate inner air-filled pad on the front and back. This effectively creates a two-layered, inflatable, pressurized structure on the inner side of the shoulder pad. After the shoulder pad is secured, further pressure can be applied to a specific area by inflating either the outer or inner air-filled pad, or both simultaneously. The pressure can be adjusted by controlling the air pressure, making it more suitable for wound pressure after brachial plexus decompression surgery. This targeted pressure application helps close small blood vessels, reducing the risk of further bleeding and aiding in rapid hemostasis. Furthermore, the inflated air-filled pads themselves provide cushioning and elasticity; appropriate pressure can promote local blood circulation, accelerate wound healing, and reduce the risk of tissue necrosis.

[0025] The following is a detailed description of this embodiment with reference to the accompanying drawings:

[0026] This embodiment provides a wound pressure device for brachial plexus decompression surgery. Please refer to the accompanying drawings in the instruction manual. Figure 1-3 .

[0027] like Figure 1-3 As shown, a pressure device for wound treatment after brachial plexus decompression surgery includes a tile-shaped shoulder pad 1 and a fixation strap 2 for the shoulder pad 1. The inner side of the shoulder pad 1 has plate-shaped external air cushions 3 on the front and back. On the shoulder contact side of each external air cushion 3, plate-shaped internal air cushions 4 are respectively provided on the top and bottom, with the internal air cushions 4 being smaller than the external air cushions 3. Each external air cushion 3 and internal air cushion 4 is connected to the corresponding air outlet of an external electromagnetic valve 6 via an inflation hose 5. The electromagnetic valve 6 is like a currently available electromagnetic valve and can be easily controlled by an existing PLC controller or multiple switches corresponding to the valve. Each external air cushion 3 and internal air cushion 4 is made of silicone to ensure softness upon contact. The shoulder pad 1 is made of nylon fabric, which prevents it from loosening after fixation, ensuring a secure wrapping effect.

[0028] To further wrap the shoulders, the outer side of the shoulder cover 1 is covered with an outer shaping plate 7 located at the bending part of the shoulder cover 1, and the interior of the outer shaping plate 7 is filled with an arc-shaped plastic plate for shaping.

[0029] To facilitate opening and fixing, the outer side of the fixing strap 2 is provided with a Velcro female buckle surface 8. The fixing end of the fixing strap 2 passes through the buckle 9 of the shoulder cover plate 1, and the inner side of the fixing end of the fixing strap 2 is provided with a barb structure for fastening to the Velcro female buckle surface 8. The upper and lower outer sides of the shoulder cover plate 1 are respectively provided with Velcro surfaces. The front and back of the outer shaping plate 7 are respectively fixedly connected to the outer side of the shoulder cover plate 1 by Velcro. The lower part of the shoulder cover plate 1 covering the arm is provided with an arm strap 10 fixed by Velcro.

[0030] The working principle of this utility model is as follows: The inner side of the shoulder pad 1 of this utility model is provided with an outer air-inflatable pad 3 and a second separate inner air-inflatable pad 4, which is equivalent to setting two inflatable sandwich structures on the inner side of the shoulder pad 1 for supporting and pressurizing. After the shoulder pad 1 is fixed, when it is necessary to further pressurize a corresponding part, the outer air-inflatable pad 3 or the inner air-inflatable pad 4, or both the outer air-inflatable pad 3 and the inner air-inflatable pad 4 are inflated to further inflate and pressurize the corresponding part. Moreover, the pressure can be adjusted by controlling the air pressure, which is better suited for wound pressure after brachial plexus nerve decompression surgery. It can more effectively increase local pressure, close some small blood vessels, reduce the risk of further bleeding, and help the wound stop bleeding quickly. In addition, when the outer air-inflatable pad 3 or the inner air-inflatable pad 4 is inflated, it can form a certain cushioning elasticity. With appropriate pressure, it can promote local blood circulation, accelerate the wound healing process, and reduce the risk of tissue necrosis.

[0031] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
