Description

Technical Field

[0001] This utility model belongs to the field of spinal cord injury rehabilitation technology, specifically relating to an adaptive pressure ulcer support brace for spinal cord injury rehabilitation. Background Technology

[0002] During the thoracic and lumbar spine rehabilitation phase, patients with spinal cord injuries need to wear support braces to restrict spinal movement. Conventional support braces consist of two sets of rigid brace components connected by side straps to form a trunk containment area. Airbags are placed on the inner side of the rigid brace to distribute wearing pressure. For example, a thoracic and lumbar spine fixation brace disclosed in Chinese patent document CN119279894A consists of two sets of rigid brace components connected by side straps. The rigid brace components include a left support plate, a right support plate, and a middle adjustment plate. The width of the left and right support plates is adjusted by screws to the middle adjustment plate. Buffer airbags are placed on the inner side of each brace.

[0003] However, in the aforementioned types of thoracolumbar spine fixation braces, the left and right support plates, except for the side that connects with the central adjustment plate, have rigid edges. During actual use, the rigid edges continuously shift and compress against the soft tissues of the trunk during patient movement. Because the rigid edges cannot adapt to changes in body shape, the sharp edges create significant pressure on local tissues, causing discomfort. With prolonged wear, local tissues may experience ischemia due to continuous pressure, potentially leading to pressure sores. This limits the duration of continuous wear, affecting rehabilitation training effectiveness and patient compliance. Therefore, optimization and improvement of the existing support brace structure are necessary. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing thoracic and lumbar spine fixation braces, such as the lack of flexible cushioning structure at the edge of the rigid protective plate and the tendency to cause pressure sores and discomfort after long-term wear, and to provide an adaptive pressure sore prevention support brace for spinal cord injury rehabilitation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adaptive pressure ulcer support brace for spinal cord injury rehabilitation includes two support plate assemblies and side connecting straps. The two support plate assemblies are joined together by the side connecting straps to form a trunk accommodating space. Each support plate assembly includes a rigid support plate and a flexible skirt. The flexible skirt is integrally set on the outer periphery of the rigid support plate and can bend adaptively with the pressure. The inner side of the rigid support plate is provided with a main support airbag, and the inner side of the flexible skirt is provided with a skirt support airbag. The inner surfaces of the main support airbag and the skirt support airbag are covered with an elastic liner.

[0006] Preferably, each rigid support plate includes a first support plate, a second support plate, and an intermediate adjustment plate. The first and second support plates are symmetrically assembled on the left and right sides of the intermediate adjustment plate. The sides where the first and second support plates and the intermediate adjustment plate meet are not provided with flexible skirts. The other three sides of the first and second support plates are integrally formed with flexible skirts. The skirt support airbags are fitted and arranged on the inner side of the flexible skirts, and the skirt support airbags are continuously arranged along the flexible skirts of the three sides of the first and second support plates.

[0007] Preferably, the flexible skirt is made of a flexible material that adapts to bending deformation when compressed by the torso to conform to the body's contours.

[0008] Preferably, the main support airbag includes a first support airbag disposed inside the first support plate, a second support airbag disposed inside the second support plate, and an intermediate support airbag disposed inside the intermediate adjustment plate. The first support airbag, the second support airbag, and the intermediate support airbag are evenly arranged inside the rigid support plate, and the thickness of each main support airbag and the skirt support airbag is consistent on the side facing the torso accommodating space.

[0009] Preferably, the elastic liner completely covers the inner surface of all main support airbags and skirt support airbags, and the outer periphery of the elastic liner is fixedly connected to the flexible skirt.

[0010] Preferably, the two ends of the side connecting strip are fixedly connected to the rigid support plates of the two support plate assemblies.

[0011] Preferably, the intermediate adjusting plate has multiple positioning holes spaced apart laterally, and the first support plate and the second support plate each have a long positioning groove spaced laterally. A locking screw passes through the long positioning groove and is inserted and fixed in any of the positioning holes. When the locking screw is loosened, the first support plate and the second support plate can slide laterally along the long positioning groove to adjust the overlap distance with the intermediate adjusting plate. Tightening the locking screw completes the position locking.

[0012] Preferably, each intermediate adjustment plate is fixedly connected to an upper connecting plate at its upper end, and each upper connecting plate is provided with a shoulder strap. The shoulder straps of the two support guard plate assemblies are detachably connected by buckles.

[0013] This invention discloses an adaptive pressure ulcer support brace for spinal cord injury rehabilitation. Its core feature is an integrally formed flexible skirt along the outer edge of a rigid support plate, with an independent skirt support airbag positioned inside the flexible skirt. Compared to existing technologies, this invention offers the following advantages: the flexible skirt adapts to the pressure of the torso, bending and deforming to conform to the body's contours, transforming the rigid contact between the hard edge and soft tissue into a flexible fit, eliminating the pressure sensation on local tissues at the edges; the skirt support airbag provides additional cushioning inside the flexible skirt, working synergistically with the main support airbag to effectively disperse pressure in the edge area, preventing localized pressure concentration; the elastic liner completely covers the inner surface of all airbags, forming a smooth, conforming surface, further homogenizing contact pressure, thereby reducing the risk of pressure ulcers under long-term wear conditions, helping to extend the duration of continuous wear per session, and improving rehabilitation training effectiveness and wear compliance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In existing thoracic and lumbar spine fixation braces, except for the side that connects with the middle adjustment plate, the other sides of the left and right support plates are all rigid edges. When worn, the rigid edges continuously generate relative displacement and compression with the soft tissues of the trunk, and the sharp edges create a pressure sensation on the local tissues. Long-term wear can easily lead to pressure sores.

[0022] Based on this, and to improve the problems in related technologies, embodiments of this application provide an adaptive pressure ulcer support brace for spinal cord injury rehabilitation, such as... Figure 1 and Figure 2 As shown, it includes two support guard plate assemblies 1 and side connecting strips 2. The two support guard plate assemblies 1 are enclosed by the side connecting strips 2 to form a torso housing space. Each support guard plate assembly 1 includes a rigid support guard plate 11 and a flexible skirt 12. The flexible skirt 12 is integrally set on the outer periphery of the rigid support guard plate 11 and can bend adaptively with the extrusion pressure. The inner side of the rigid support guard plate 11 is provided with a main support airbag 13, and the inner side of the flexible skirt 12 is provided with a skirt support airbag 14. The inner surfaces of the main support airbag 13 and the skirt support airbag 14 are covered with an elastic liner 15.

[0023] The rigid support plate 11, serving as the main support framework of the entire protective gear, is made of a material with a certain degree of rigidity and provides stable support and fixation for the patient's torso. The flexible skirt 12 is integrally formed on the outer periphery of the rigid support plate 11; its material rigidity is less than that of the rigid support plate 11, allowing it to bend and deform under torso compression. The main support airbag 13 is located on the inner side of the rigid support plate 11, providing cushioning support over a large area of ​​the front and back of the torso. The skirt support airbag 14 is located on the inner side of the flexible skirt 12, bending and deforming along with it, providing independent cushioning for the edge areas of the rigid support plate 11. The elastic liner 15 covers the inner surface of all airbags, directly contacting the patient's torso and integrating the contact surfaces separated by the airbags into a continuous, flat, and conforming surface.

[0024] When the support brace is worn, the patient's torso is held between two support plate assemblies 1, and the main support airbag 13 and the skirt support airbag 14 adapt to the wearing pressure. When the patient's torso moves, the outer peripheral edge of the rigid support plate 11 contacts the torso through the flexible skirt 12. The flexible skirt 12 bends adaptively with the compressive force, conforming to the changes in the body surface contour, and the skirt support airbag 14 deforms synchronously to provide cushioning, so that a flexible transition is formed between the rigid edge and the soft tissue.

[0025] In the above technical solution, the flexible skirt 12 adapts to the body surface by bending and bending with the compression of the torso. Combined with the buffering effect of the skirt support airbag 14, a flexible transition is formed between the edge of the rigid support plate 11 and the soft tissue of the torso, avoiding direct pressure of the rigid edge on local tissue. At the same time, the elastic liner 15 integrates the contact surfaces of each airbag into a continuous and flat contact surface, so that the pressure in the edge area is effectively dispersed.

[0026] This utility model further proposes, such as Figure 2 and Figure 4 As shown, each rigid support plate 11 includes a first support plate 111, a second support plate 112, and an intermediate adjustment plate 113. The first support plate 111 and the second support plate 112 are symmetrically assembled on the left and right sides of the intermediate adjustment plate 113. The sides where the first support plate 111, the second support plate 112, and the intermediate adjustment plate 113 meet are not provided with flexible skirts 12. The other three sides of the first support plate 111 and the second support plate 112 are integrally formed with flexible skirts 12. The skirt support airbags 14 are fitted and arranged on the inner side of the flexible skirts 12, and the skirt support airbags 14 are continuously arranged along the flexible skirts 12 on the three sides of the first support plate 111 and the second support plate 112.

[0027] Each rigid support plate 11 is composed of three plates, with the middle adjustment plate 113 located in the center, and the first support plate 111 and the second support plate 112 located on the left and right sides respectively. The flexible skirt 12 is only provided on the three free side edges of the first support plate 111 and the second support plate 112 that are not connected to the middle adjustment plate 113, while the sides that are connected to each other are not provided with the flexible skirt 12. The skirt support airbags 14 are continuously arranged along the flexible skirt 12 to ensure that the entire edge area is buffered and protected.

[0028] In one specific implementation, the first support plate 111 and the second support plate 112 are symmetrically arranged, and the middle adjusting plate 113 is a vertically extending plate. The inner surfaces of the three together form an arc-shaped support surface that fits against the torso. The flexible skirt 12 is integrally formed with the first support plate 111 and the second support plate 112, and the rigid and flexible parts can be integrally connected by two-color injection molding or insert injection molding processes.

[0029] As an alternative embodiment, those skilled in the art can also use adhesive or hot-melt bonding to fix the flexible skirt 12 to the outer periphery of the rigid support plate 11, as long as the connection strength between the flexible skirt 12 and the rigid support plate 11 is sufficient to withstand the pulling force during the wearing process.

[0030] In the above technical solution, the flexible skirt 12 is only set on the free side edge of the first support plate 111 and the second support plate 112. The flexible skirt 12 is not set on the side edge that is connected to each other, so as to avoid the interference of the flexible skirt 12 on the width adjustment function. At the same time, the skirt support airbag 14 is continuously arranged along the three sides of the flexible skirt 12 to ensure uninterrupted buffer protection of the entire edge area.

[0031] The present invention further proposes that the flexible skirt 12 is made of a flexible material, and the flexible skirt 12 produces adaptive bending deformation to conform to the body surface contour when subjected to torso compression.

[0032] The flexible skirt 12 has a lower material stiffness than the rigid support plate 11, allowing it to bend and deform under pressure from the torso. The flexible skirt 12 is also thinner than the rigid support plate 11, ensuring sufficient bending freedom while maintaining adequate support.

[0033] In one specific implementation, the flexible skirt 12 can be made of materials such as thermoplastic elastomers, silicone rubber, or polyurethane elastomers, which provide slight support while maintaining flexibility. The rigid support plate 11 can be made of engineering plastics such as polypropylene, polyethylene, or ABS. The thickness of the flexible skirt 12 can be set to one-third to one-half the thickness of the rigid support plate 11, so that it preferentially bends and deforms under compressive force.

[0034] In the above technical solution, the flexible skirt 12 actively bends and deforms to conform to the body surface contour when squeezed by the torso. Compared with the passive resistance of rigid edges, this active adaptive deformation eliminates the pressure sensation on local tissues at the edge corners.

[0035] The present invention further proposes that the main support airbag 13 includes a first support airbag 131 disposed inside the first support plate 111, a second support airbag 132 disposed inside the second support plate 112, and an intermediate support airbag 133 disposed inside the intermediate adjustment plate 113. The first support airbag 131, the second support airbag 132, and the intermediate support airbag 133 are evenly arranged inside the rigid support guard plate 11, and the thickness of each main support airbag 13 and the skirt support airbag 14 facing the torso accommodating space is consistent.

[0036] Each main support airbag 13 and the skirt support airbag 14 can be made of the same material and have the same wall thickness, ensuring that the thickness of all airbags is consistent, thus providing a flat foundation for the elastic liner 15. Furthermore, the airbags are smoothly connected, abutting or integrally joined at adjacent edges, or transitioned through overlapping edges or small gaps between airbags, avoiding the formation of protrusions or depressions at the airbag joints.

[0037] In one specific implementation, the first support airbag 131, the second support airbag 132, and the intermediate support airbag 133 are all flat, sac-like structures, or irregularly shaped sacs adapted to the shape of the corresponding plates, with their planar shapes matching the shape of their respective support plates. The skirt support airbag 14 is a long, strip-shaped sac structure, continuously arranged along the extension direction of the flexible skirt 12. Each airbag can be inflated through an independent inflation port, or they can be interconnected through connecting pipes for unified inflation.

[0038] In the above technical solution, each main support airbag 13 and the skirt support airbag 14 are smoothly connected and have the same thickness, so that the elastic liner 15 has a flat laying foundation and avoids the unevenness at the airbag connection point from causing local pressure on the torso.

[0039] The present invention further proposes that the elastic liner 15 completely covers the inner surface of all the main support airbags 13 and the skirt support airbags 14, and the outer peripheral edge of the elastic liner 15 is fixedly connected to the flexible skirt 12.

[0040] The elastic liner 15 is a one-piece flexible sheet, the outline of which matches the inner surface outline of the entire support panel assembly 1. The outer peripheral edge of the elastic liner 15 is fixedly connected to the flexible skirt 12, which can be achieved through detachable connection or fixed connection such as sewing, bonding or heat pressing.

[0041] As one specific implementation, the elastic liner 15 can be made of materials such as three-dimensional mesh fabric, elastic cotton, or memory foam, which are both elastic and breathable. The outer periphery of the elastic liner 15 is fixedly connected to the inner edge of the flexible skirt 12 by stitching, so that the elastic liner 15 remains flat when the airbag is inflated.

[0042] In the above technical solution, the elastic liner 15 is completely covered on the inner surface of all airbags, integrating the contact surfaces of each airbag into a continuous and flat fitting surface, making the contact pressure more uniform throughout the patient's torso.

[0043] The present invention further proposes that the two ends of the side connecting strip 2 are respectively fixedly connected to the rigid support plate 11 of the two support plate assemblies 1.

[0044] The side connecting strip 2 serves as a connector between the two support plate assemblies 1. One end of the side connecting strip 2 is fixedly connected to the rigid support plate 11 of one of the support plate assemblies 1, and the other end is fixedly connected to the rigid support plate 11 of the other support plate assemblies 1. The side connecting strip 2 can be made of elastic or non-elastic webbing and is fixedly connected to the rigid support plate 11 by sewing.

[0045] In the above technical solution, the side connecting strip 2 encloses the two support guard plate assemblies 1 into a ring structure, thereby achieving circumferential fixation of the patient's torso.

[0046] The present invention further proposes that the intermediate adjusting plate 113 is provided with a plurality of positioning holes 1131 spaced apart in the transverse direction, and the first support plate 111 and the second support plate 112 are respectively provided with elongated positioning grooves 114 in the transverse direction. An external locking screw passes through the elongated positioning groove 114 and is inserted and fixed in any of the positioning holes 1131. When the locking screw is loosened, the first support plate 111 and the second support plate 112 can slide laterally along the elongated positioning groove 114 to adjust the overlap distance with the intermediate adjusting plate 113, and the locking screw is tightened to complete the position locking.

[0047] The positioning holes 1131 are arranged laterally at intervals along the intermediate adjusting plate 113, and the elongated positioning grooves 114 extend laterally along the first support plate 111 and the second support plate 112. During assembly, the locking screw passes through the elongated positioning groove 114 and is screwed into the corresponding positioning hole 1131 to fix the first support plate 111 or the second support plate 112 to the intermediate adjusting plate 113. When the width needs to be adjusted, the locking screw is loosened, and the first support plate 111 or the second support plate 112 can slide relative to the intermediate adjusting plate 113 along the extension direction of the elongated positioning groove 114 to change the overlap distance. After adjustment, the locking screw is tightened to complete the fixation.

[0048] In one specific implementation, the intermediate adjustment plate 113 has three to five positioning holes 1131 evenly spaced along its transverse direction to accommodate patients of different body types. The elongated positioning groove 114 is 20 mm to 40 mm long, allowing each support plate to have sufficient adjustment range.

[0049] In the above technical solution, the stepless adjustment and multi-level positioning of the overall horizontal width of the rigid support plate 11 are realized through the cooperation of the long positioning groove 114 and multiple positioning holes 1131, so that the same protective gear can be adapted to patients of different body types.

[0050] The present invention further proposes that an upper connecting plate 115 is fixedly connected to the upper end of each intermediate adjusting plate 113, and a shoulder strap 3 is provided on each upper connecting plate 115. The shoulder straps 3 of the two supporting guard plate assemblies 1 are detachably connected by buckles.

[0051] The upper connecting plate 115 extends upward from the upper end of the middle adjusting plate 113. One end of the shoulder strap 3 is fixed to the upper connecting plate 115, while the other end is free and equipped with a buckle. When worn, the shoulder straps 3 of the two support plate assemblies 1 pass over the patient's shoulders and are connected to each other via the buckle, securing the upper end of the protective gear to the patient's shoulders. Furthermore, corresponding support airbags or cushioning pads can be provided on the upper connecting plate 115 to improve the comfort of the corresponding contact area of ​​the human body.

[0052] In the above technical solution, the shoulder strap 3 is detachably connected by a buckle, which realizes the fixation of the shoulder at the upper end of the protective gear and prevents the protective gear from slipping down during the wearing process.

[0053] The working principle of this adaptive pressure ulcer support brace for spinal cord injury rehabilitation is as follows: When worn, two support plate assemblies 1 are placed on the patient's chest and back respectively, and secured together by side connecting straps 2, thus holding the torso between the two support plate assemblies 1. The main support airbag 13 and the skirt support airbag 14 adapt to the wearing pressure, and the elastic liner 15 is in direct contact with the patient's torso. When the patient's torso moves, the outer periphery of the rigid support plate 11 contacts the torso through the flexible skirt 12. The flexible skirt 12 adapts to the pressure, bending to conform to the changes in the body surface contour, while the skirt support airbag 14 deforms synchronously to provide cushioning, creating a flexible transition between the rigid edge and soft tissue. When the brace width needs adjustment, the locking screw is loosened, and the first support plate 111 and the second support plate 112 slide laterally along the elongated positioning groove 114 to adjust the overlap distance with the intermediate adjustment plate 113. After adjustment, the locking screw is tightened to complete the fixation.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
