Description

Technical Field

[0001] The utility model relates to the field of rehabilitation medical equipment, in particular to a pressure pad used for a scoliosis brace. Background Art

[0002] Scoliosis refers to a spinal deformity in which one or more segments of the spine bend sideways or are accompanied by vertebral rotation. The internationally recognized treatments for scoliosis are surgical treatment and conservative treatment. Surgery is traumatic and risky. Therefore, scoliosis braces have become the first choice for patients. Before the end of growth and development, the scoliosis brace can effectively control the progression of early scoliosis by continuously applying corrective force to the spine, especially for mild idiopathic scoliosis.

[0003] The scoliosis of patients is different, and the design of scoliosis is more dependent on clinical experience. Applying pressure to the patient's spine and wearing it in the pressure area for a long time will also cause pain and pressure sores in the patient. The traditional method is to use EVA foam material to polish and stick it on the orthosis to increase support and relieve discomfort, but the patient needs to wear the orthosis for more than 20 hours a day. EVA foam is not breathable and bacteria breed, which affects the patient's skin health. At the same time, the pressure pad of each patient needs to be reprinted, which increases the workload. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a pressure pad for a scoliosis brace, which can be better breathable so that patients will not develop pressure sores when wearing it for a long time.

[0007] Preferably, a first curvature is provided on the human body contacting surface of the central area, the curvature of the first curvature is set toward the device connecting surface, and the angle range is 65°-75°, and the straight-line distance between the central area and the two end points of the first curvature is 75mm-85mm.

[0008] Preferably, on the human body contacting surface of the pressure pad, a first angle is provided between the first transition area and the horizontal plane, and the angle range of the first angle is 22°-35°.

[0009] Preferably, on the human body contacting surface of the pressure pad, a second angle is provided between the second transition area and the horizontal plane, and the angle range of the second angle is 25°-35°.

[0010] Preferably, the pressure pad is provided with a plurality of connection layers inside, and a plurality of evenly distributed support points are provided on the connection layers, and each support point is respectively connected to other support points close to itself, so as to form a prismatic structure.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0024] It should also be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0025] The specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 6 As shown, a pressure pad 1 for a scoliosis brace is formed in one piece by 3D printing, and includes a central area 2 located in the middle, a first transition area 3 located on the left and right sides of the central area 2, and a second transition area 4 located on the upper and lower sides of the central area 2. The first transition area 3 and the second transition area 4 are integrally connected to the central area 2, and the thickness of the first transition area 3 and the second transition area 4 gradually thickens from the edge to the connection with the central area 2. On the pressure pad 1, the front and back sides thereof are respectively a human body abutment surface 5 and a device connection surface 6; when the pressure pad 1 needs to be used, the device connection surface 6 needs to be fixed to the scoliosis brace by means of Velcro, glue, screws, etc., and the patient's thoracolumbar pressure area or other pain-sensitive areas can be attached to the human body abutment surface 5.

[0027] In order to better avoid the problem of pressure sores caused by long-term wearing, the pressure pad 1 uses medical-grade photosensitive resin and TPU materials for 3D printing. The above-mentioned printing setting can better set a number of interconnected 3D-structured air holes 7 inside it, and the porosity of the air holes 7 accounts for 60%-90% of the pressure pad 1.

[0028] Specifically, the diameter of the ventilation holes 7 on the first transition zone 3 and the second transition zone 4 is larger than the diameter of the ventilation holes 7 on the central zone 2. This arrangement can make the human body contact surface 5 of the central zone 2 smoother and more comfortable.

[0029] like Figures 1 to 5 As shown, a first curvature is provided on the human body abutment surface 5 of the central area 2, the curvature of the first curvature is bent toward the device connection surface 6, and the angle range is 65°-75°, and the straight-line distance between the central area 2 and the two end points of the first curvature is 75mm-85mm.

[0030] Providing this curvature on the central area 2 can better fit the human body and further improve comfort.

[0031] like Figures 1 to 6 As shown, on the human body contact surface 5 of the pressure pad 1, a first angle is provided between the first transition zone 3 and the horizontal plane, and the angle range of the first angle is 22°-35°, and a second angle is provided between the second transition zone 4 and the horizontal plane, and the angle range of the second angle is 25°-35°.

[0032] The upper and lower ends of the first transition zone 3 are provided with a second curvature on the human body contact surface 5, and the angle range of the second curvature is 80°-88°. The left and right ends of the second transition zone 4 are provided with a third curvature on the human body contact surface 5, and the angle range of the third curvature is 50°-58°.

[0033] The above arrangement can increase the fit with the brace and the comfort of the patient.

[0034] like Figures 1 to 4 As shown, in order to better reflect the structure of the pressure pad 1, several connecting layers are provided inside it, and several evenly distributed support points 8 are provided on the connecting layers, and each support point 8 is respectively connected to other support points 8 close to itself, so as to form a prism structure, and the prism structure can be a triangular prism or a quadrangular prism or other prism structures. The internal prism structure of the pressure pad 1 is combined with the material to better ventilate, thereby ensuring that no pressure sores will be generated.
