Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a spinal orthosis for ankylosing spondylitis. Background Technology

[0002] Ankylosing spondylitis is a chronic inflammatory rheumatic disease that mainly affects axial joints such as the sacroiliac joints and spine, but can also involve peripheral joints and extra-articular organs such as the eyes and intestines. Its typical symptoms are inflammatory low back pain, which manifests as morning stiffness and pain that worsens after rest and is relieved by activity. As the disease progresses, patients may experience decreased spinal mobility, joint ankylosis, and even deformities.

[0003] Current corrective treatments for ankylosing spondylitis mainly combine physical therapy with exercise correction. The primary goal is to maintain the range of motion of the spine and joints, strengthen the core muscles and back extensor muscles, and counteract the tendency of flexion deformity to achieve the corrective purpose. However, the exercise correction process under guidance needs to be combined with resistance training based on the exercise posture. The corrective effect of the current training is affected by the guidance method and the degree of standardization of the patient's movements, resulting in large individual differences and failing to achieve the expected corrective effect. Utility Model Content

[0004] The technical problem this invention aims to solve is that in existing training procedures for spinal correction in ankylosing spondylitis, patients are unable to complete the training movements independently and effectively, making it difficult to achieve the desired corrective training effect. To address this problem, this invention provides a spinal correction device for ankylosing spondylitis.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: including a cushion, with a handle seat and a leg pad respectively provided at both ends of the cushion, and the horizontal height of the cushion, handle seat and leg pad is related to the human limb support position;

[0006] A sliding handle bracket is provided at the bottom between the pad and the handle seat, and a pressure shaft is fixed between the end of the sliding handle bracket and the handle seat. A piston tube is provided between the handle seat and the pad, and the pressure shaft and the piston tube are in sliding fit.

[0007] A lifting support is fitted onto the pad, and a lifting shaft extends and is fixed to the bottom of the lifting support. A lifting cylinder is provided in the pad that is matched with the lifting shaft, and the change in the air volume of the lifting cylinder is positively correlated with the lifting height of the lifting shaft. A valve pipe is provided through the bottom of the lifting cylinder, and the valve pipe is connected to the piston pipe.

[0008] A further preferred embodiment: the lifting support is a rigid filling pad with an arc surface.

[0009] A further preferred embodiment: the amount of air filling in the valve tube is matched with the sliding stroke of the pressure shaft and the sliding stroke of the lifting shaft.

[0010] A further preferred embodiment: guide rods are slidably fitted between the lifting support and the pad on both sides.

[0011] A further preferred embodiment: the pad has a pair of snap-fit ​​tension bands symmetrically arranged on the end side near the leg pad, and an elastic pelvic belt is fixed to the outer end of one of the tension bands.

[0012] A further preferred embodiment: a photoelectric sensor is fixed to the end of the lifting cylinder and the lifting support, and the photoelectric sensor is externally connected to an Internet of Things transmission module.

[0013] The beneficial effects of this utility model are:

[0014] This spinal orthosis for ankylosing spondylitis is based on the cat-and-camel training method. Under its support, the horizontal displacement of the handle seat along the sliding arm causes the inner pressure shaft and piston tube to move in a linked piston motion. The sliding displacement of the pressure shaft under the piston motion fills the piston tube and valve tube with gas into the lifting cylinder, which in turn drives the lifting shaft and lifting support to move accordingly. The lifting support serves as a support structure for the trainee's abdomen. Combined with the flexion and extension movements during the cat-and-camel training, it completes the resistance training of the spine and abdominal core muscles. The linkage between the position of the lifting support and the position of the handle seat can maintain the support height throughout the training movement, avoid training injuries, and ensure the standard of training movements, thus improving the corrective training effect and safety of the orthosis.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-3The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples of implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0021] A spinal orthosis for ankylosing spondylitis includes a base 1, with a handle seat 2 and a leg pad 3 respectively provided at both ends of the base 1. The horizontal height of the base 1, handle seat 2 and leg pad 3 is associated with the human limb support position.

[0022] A sliding handle bracket 7 is mounted at the bottom between the pad 1 and the handle seat 2, and a pressure shaft 8 is fixedly inserted between the end of the sliding handle bracket 7 and the handle seat 2. A piston tube 9 is inserted between the handle seat 2 and the pad 1, and the pressure shaft 8 and the piston tube 9 are in sliding engagement.

[0023] A lifting support 6 is fitted on the pad 1. A lifting shaft 11 is fixedly extended from the bottom of the lifting support 6. A lifting cylinder 10 is provided in the pad 1 to be matched with the lifting shaft 11. The change in air volume of the lifting cylinder 10 is positively correlated with the lifting height of the lifting shaft 11. A valve pipe 13 is provided through the bottom of the lifting cylinder 10 and is connected to the piston pipe 9.

[0024] This orthotic device is based on cat-and-camel training. The pad 1 serves as the lumbar height anchor point for the patient's limb support position. The front and rear handle seats 2 and leg pads 3 serve as the pressure points for the patient's hands and knees. During training, flexion and extension movements cause the hands to move the handle seats 2 horizontally on the slide frame 7. As the handle seats 2 move, the pressure shaft 8 and piston tube 9 move synchronously. This piston movement changes the amount of air filling the piston tube 9 and valve tube 13, thus altering the air volume in the lifting cylinder 10. This change in air supply to the lifting cylinder 10 drives the lifting shaft 11 to move axially, achieving the desired lifting motion. The lifting control of the lifting support 6 is as follows: when in the flexed position, the hand moves the handle seat 2 closer to the pad seat 1, and the lifting support 6 continuously rises to support the patient's waist and abdomen. This helps maintain the patient's flexed position and avoids excessive compensation due to insufficient abdominal core strength, thus avoiding excessive pressure and improving safety during training. When in the extended position, the hand moves the handle seat 2 away from the pad seat 1. During this process, the volume of the air chamber in the valve tube 13 and piston tube 9 increases, and the gas filled in the lifting cylinder 10 flows back to the piston tube 9 and valve tube 13. At this time, the lifting shaft 11 will sink as the handle seat 2 moves away to maintain the support height of the pad seat 1 in conjunction with the extension movement.

[0025] This type of orthosis has a simple structure and is easy to operate. It can ensure that the patient's training movements are standardized while avoiding spinal injury, thus improving the orthosis's practicality and safety.

[0026] Among them, the lifting support 6 is a rigid filling pad with an arc surface. The rigid pad structure meets the support strength and pressure of the lumbar spine position in ankylosing spondylitis, and avoids local collapse during support, which may cause the lumbar spine joints to deviate.

[0027] Based on the above, the filling air volume in the air valve tube 13 is matched with the sliding stroke of the pressure shaft 8 and the sliding stroke of the lifting shaft 11. The matching filling air volume and sliding stroke can ensure that the distance between the handle seat 2 and the pad seat 1 and the support height of its lifting support 6 meet the standard of the cat-camel training action. At the same time, the filling air volume specification can be adjusted according to individual differences, depending on the professional rehabilitation physician.

[0028] Furthermore, guide rods 12 are slidably fitted between the lifting support 6 and the pad 1 on both sides, such as... Figure 3 As shown, the axial lifting displacement accuracy of the lifting support 6 is further improved by the guide rod 12, so as to avoid the collapse and misalignment of the local support position from affecting the support position of the spinal joint.

[0029] Furthermore, the pad 1 is symmetrically provided with a pair of snap-fit ​​tension bands 4 on the side near the end of the leg pad 3, and an elastic pelvic band 5 is fixed to the outer end of one of the tension bands 4. The pelvic band 5 can be wrapped and fixed to the patient's pelvic position to maintain the stability of the pelvic and leg position during corrective training and improve the accuracy of training movements.

[0030] Furthermore, a photoelectric sensor 14 is fixed to the end of the lifting cylinder 10 and the lifting support 6. The photoelectric sensor 14 is connected to an Internet of Things (IoT) transmission module. The photoelectric sensor 14 is an optional accessory. It can measure the distance between the lifting cylinder 10 and the lifting support 6 in real time based on the principle of infrared ranging sensor, that is, to provide feedback on the lifting height of the lifting support 6. With the help of the IoT transmission module, the height position node of the lifting support 6 under each training action is fed back, which helps rehabilitation physicians determine the training plan based on the data. Alternatively, it can be used with software such as voice reminders to prompt trainees whether the height under the corresponding action meets the standard.

[0031] During training, the cat-camel training is used as the basis, with the pad 1 as the waist height anchor point for the patient's limb support position, and the front and rear handles 2 and leg pads 3 as the force points for the patient's hand support position and the force points for the knees of the legs.

[0032] During the training process, the flexion and extension movements are used to drive the handle seat 2 to make relative horizontal displacement on the slide frame 7. When the handle seat 2 is displaced, the pressure shaft 8 and the piston tube 9 will move synchronously. The piston movement stroke changes the amount of air filled in the piston tube 9 and the air valve tube 13. That is, when the piston moves, the amount of air filled in the lifting cylinder 10 will be changed. The change in the air feed in the lifting cylinder 10 will drive the lifting shaft 11 to move axially, thus realizing the lifting control of the lifting support 6.

[0033] When in the flexed position, the hand moves the handle seat 2 closer to the pad seat 1, and the lifting support 6 continuously rises and supports the patient's waist and abdomen. This helps maintain the patient's flexed position and avoids excessive compensation due to insufficient abdominal core strength in the local joints, thus avoiding excessive pressure and improving safety during training.

[0034] When in the extended position, the hand moves the handle seat 2 away from the pad 1. During the process, the volume of the air chamber in the valve tube 13 and piston tube 9 increases. The gas filled in the corresponding lifting cylinder 10 will flow back to the piston tube 9 and valve tube 13. At this time, the lifting shaft 11 will sink as the handle seat 2 moves away, so as to maintain the support height position of the pad 1 in coordination with the extension action.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
