Description

Technical Field

[0001] The present invention relates to the field of posture correction, and more particularly to a cervical vertebra orthosis and a preparation method thereof. Background Art

[0002] Modern devices have increased the time people spend sitting and the time people use mobile phones and computers. For a long time, people bow their heads to play with mobile phones, work at desks, watch TV or read books half-lying down, which keeps the cervical spine in a flexed state for a long time.

[0003] Long-term bowing of the head will cause the cervical spine to bear a huge burden. The pressure on the neck increases with the angle of the head bending. The pressure in the cervical intervertebral disc increases, the neck muscles are unevenly stressed, the muscles and ligaments at the back of the neck are stretched and strained, the muscle strength decreases, the vertebral body becomes unstable, and the physiological curvature changes. Cervical hyperextension will cause excessive pressure on the neck, resulting in insufficient blood supply to the head and neck, and it is easy to cause airway obstruction, causing hypoxia and ischemia, and symptoms such as headache, dizziness, tinnitus, and insomnia.

[0004] Existing cervical orthoses often only come in large, medium and small sizes, which results in poor comfort during use and makes it difficult to wear them for a long time, thereby preventing users from persisting in long-term use.

[0005] The present application aims to provide a cervical vertebra orthosis. Summary of the invention

[0006] The present invention overcomes the shortcomings of existing orthoses that the size cannot fully fit the human body, resulting in poor usage experience and difficulty in long-term wearing, and provides a cervical vertebra orthosis and a preparation method thereof, which can fit the human body to achieve a better usage experience.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: A cervical vertebra orthosis comprises an elastic sheet body and an external elastic part. The elastic sheet body is fitted with the orthopedic object. The elastic sheet body comprises a neck support, a transition part, a shoulder blade fitting part and a forward-extending chest fitting part. The neck support is fitted with the anterior cervical triangle area of ​​the orthopedic object. The transition part, the shoulder blade fitting part and the forward-extending chest fitting part are symmetrical about the two sides of the neck support. The transition part transitions to the two sides along the shoulder and extends backward. The shoulder blade fitting part is fitted with the shoulder blade of the orthopedic object. The forward-extending chest fitting part extends from the armpit to the front side. The external elastic part connects the forward-extending chest fitting parts on the left and right sides near the outer edge.

[0008] The elastic sheet itself is elastic. In order to adapt to the human body, the elastic sheet forms a corresponding pulling structure, and the elastic sheet is elastic. The neck support provides a fit to the neck. When posture problems such as forward neck tilt and round shoulders and hunchback occur, the elastic sheet is pulled, generating elastic force to pull the neck support and act on the neck support, thereby forcing people to lift their necks and avoid posture problems. Due to the elasticity of the elastic sheet itself, the neck support can deform when applying force to the orthopedic object, increasing the surface area of ​​the neck support, reducing the pressure on the front of the neck, and improving the user experience.

[0009] The transition part fits with the shoulder, and when the shoulder shrugs, the transition part is stretched, thereby generating elastic force, which will counteract the above posture. In addition, the transition part connects the neck support and the shoulder blade fitting part, which is used to transmit the pulling force when the posture changes.

[0010] The shoulder blade contact part is used to build tension and is also the main source of elastic force. By analyzing the body posture, whether it is a forward neck or a rounded shoulder, the shoulder blade will bulge backward relative to the healthy body posture, so that the elastic sheet at the shoulder blade is stretched, generating elastic force, thereby building tension, and through force transmission, the front neck and / or shoulder blade of the orthopedic object are pulled, so that the orthopedic object can return to a normal posture.

[0011] The elastic sheet is extended forward and connected to the chest with an external elastic part, so that the elastic sheet and the external elastic part form an elastic system connected end to end. The whole elastic system is saddle-shaped, and the lateral tension of the front neck and chest is balanced with the longitudinal tension of the back. Since the elastic sheet is designed according to the body shape of the orthotic object, it fits the human body as much as possible. Therefore, when the body shape of the orthotic object is unhealthy, the orthosis can intervene and apply elastic force to force the orthotic object to restore a healthy body shape.

[0012] Preferably, the neck support is fitted on the surface of the submental triangle and carotid triangle. The neck in this area is the main area where the reverse arch occurs, and it is relatively labor-saving to support the neck in this area. The number of nerves and blood vessels in this area is less than that in the adjacent area, and the use experience is better, thereby supporting long-term daily use.

[0013] Preferably, the neck support is provided with a widened area at the position corresponding to the carotid artery. The widened area increases the width, which can reduce the pressure on the carotid artery and improve the feeling.

[0014] Preferably, a reinforcement area is provided between the supporting neck and the transition part, and the reinforcement area is located on the side of the neck and extends toward the occipital bone. The structure is used to correct the neck in the left and right directions, and when the posture of the object to be corrected includes a lateral tilt of the neck, correction is performed. When the neck tilts to one side, the elastic sheet on one side is pulled to generate elastic force to provide tension for correction.

[0015] Preferably, the shoulder blade contact portion is contacted with a position close to the outer side of the corresponding shoulder blade. The shoulder blade at the outer side has the largest displacement when the body posture is poor, and can produce the largest deformation, thereby generating a force sufficient to pull back the cervical vertebra.

[0016] Preferably, the external elastic member includes a first elastic member and a second elastic member, one end of the elastic member is fixedly connected to the front extension of the left side against the chest, one end of the second elastic member is fixedly connected to the front extension of the right side against the chest, and the other end of the elastic member is detachably connected to the other end of the second elastic member. The structure is used to realize the detachability of the orthosis. If the external elastic member is an integral structure with the elastic sheet, the device will become a closed loop structure and cannot be worn. In addition, the disassembly point is set between the first elastic member and the second elastic member, so that the stress point can be set at the first elastic member and the second elastic member, which are relatively easier to replace, to avoid damage to the more expensive elastic sheet.

[0017] Preferably, the elastic sheet is made of silicone, which is elastic, suitable for 3D printing, and not prone to allergies when worn for a long time.

[0018] A method for preparing a cervical vertebra orthosis, used for preparing the cervical vertebra orthosis as described above, the preparation method comprising: Step 1: Perform 3D scanning on the orthopedic object to obtain the position of each feature point and measure the length of the line connecting the corresponding feature points; Step 2: Import the characteristic points and their connecting lines obtained in step 1 into the modeling software to adjust the corresponding size of the cervical orthosis to form a corresponding digital model; Step 3: Perform 3D printing based on the digital model to form an elastic sheet; Step 4: Install the external elastic member on the elastic sheet; Step 4: Wear the finished product on the orthopedic subject and adjust it according to the subjective feelings of the orthopedic subject and the operator's assessment of the body shape of the orthopedic subject.

[0019] The model is taken to obtain each feature point and the data of each dimension, and then the model is built based on this data and 3D printing is performed to provide a personalized corresponding elastic sheet, so that the component fits the body surface of the orthopedic object. Then the adjustment is performed while wearing to improve the wearing experience.

[0020] In summary, the orthosis prepared by this method has the advantages of stable structure and high comfort.

[0021] Compared with the prior art, the present invention has the following beneficial effects: (1) The elastic system consisting of the elastic sheet and the external elastic member connected end to end is manufactured in a personalized manner. In a healthy body shape, it does not participate in the correction, but in an unhealthy body shape, it participates in the correction and pulls the correction object toward a healthy body shape. (2) The cervical orthosis can correct the cervical spine in multiple directions; (3) The cervical orthosis is designed to widen highly sensitive areas such as the carotid artery to enhance physical sensation.

[0028] Example: A cervical orthosis, Figure 1 As shown, it includes an elastic sheet body 1 and an external elastic member 2. It is used to correct the cervical spine of the orthopedic subject, and intervene in a long-term wearable manner to improve the cervical kyphosis problem of the orthopedic subject. The orthopedic subject refers to a person. The term "kyphosis" means that the ideal human cervical spine should have a certain curvature and be arched. The cervical spine of the orthopedic subject to be corrected often has the problem of straightening the curvature or even arching.

[0029] The elastic sheet 1 fits the orthopedic object, and the elastic sheet 1 includes a neck support 11, a transition portion 12, a shoulder blade fitting portion 13, and a forward chest fitting portion 14. The transition portion 12, the shoulder blade fitting portion 13, and the forward chest fitting portion 14 are symmetrical about the neck support 11. Like the structure of the human body, the elastic sheet 1 of the present application is a bilaterally symmetrical structure. The neck support 11 is also symmetrical about its central axis.

[0030] In order to clearly describe the specific structure of the cervical orthosis, the present application specifically describes it in a state where it is attached to the orthotic object, and the position of each component is relatedly explained using the body position of the orthotic object.

[0031] Ginseng Figure 2 The neck support 11 fits with the anterior triangle of the neck of the orthopedic object. Specifically, the neck support 11 fits on the surface of the submental triangle and the carotid triangle. The neck in this area is the main area where the reverse arch occurs. The neck support 11 acting on this area is relatively labor-saving. The number of nerves and blood vessels in this area is less than that in the adjacent area, and the use experience is better, thereby supporting long-term daily use. The neck support 11 is a horizontal structure, and the neck support 11 also extends to the back of the human body, extending from the forehead to behind the ear.

[0032] The support neck 11 is provided with a widened area 111 at the position corresponding to the carotid artery. The widened area 111 increases the width, can reduce the pressure on the carotid artery, and improve the feeling.

[0033] Ginseng Figure 3A reinforcement area 112 is provided between the neck support 11 and the transition part 12. The reinforcement area 112 is located on the side of the neck and extends toward the occipital bone. The structure is used to correct the left and right directions of the neck. When the posture of the object to be corrected includes a lateral tilt of the neck, correction is performed. When the neck tilts to one side, the elastic sheet 1 on one side is pulled to generate elastic force to provide tension for correction.

[0034] The transition part 12 is connected to the supporting neck 11. The transition part 12 transitions to both sides along the shoulder and extends to the rear side, and its front part is located on the front side of the shoulder, and it is located on the trapezius muscle and avoids the deltoid muscle to avoid interfering with the movement of the arm.

[0035] The shoulder blade fitting part 13 fits with the shoulder blade of the orthopedic object, and specifically, the shoulder blade fitting part 13 fits with the position close to the outer side of the corresponding shoulder blade. The shoulder blade at the outer side has the largest displacement when the posture is poor, and can produce the largest deformation, thereby generating a force sufficient to pull back the cervical vertebra. The shoulder blade fitting part 13 is in a C shape that is bent toward the human spine.

[0036] The front-extending chest patch 14 extends from the armpit to the front side, and the external elastic member 2 connects the front-extending chest patch 14 on the left and right sides close to the outer edge.

[0037] Ginseng Figure 4 As shown, the external elastic member 2 includes a first elastic member 21 and a second elastic member 22, one end of the elastic member is fixedly connected to the front-extending chest member 14 on the left side, one end of the second elastic member 22 is fixedly connected to the front-extending chest member 14 on the right side, and the other end of the elastic member is detachably connected to the other end of the second elastic member 22. The structure is used to realize the detachability of the orthosis. If the external elastic member 2 is an integral structure with the elastic sheet 1, the device will become a closed-loop structure and cannot be worn. In addition, the disassembly point is set between the first elastic member 21 and the second elastic member 22, so that the stress point can be set at the first elastic member 21 and the second elastic member 22, which are relatively easier to replace, to avoid damage to the more expensive elastic sheet 1.

[0038] The connection method between the first elastic member 21 and the second elastic member 22 includes hook-and-loop connection or Velcro-type bonding, but is not limited thereto.

[0039] In other embodiments, one end of the external elastic member 2 is fixedly connected to the front chest-attaching member 14 on one side, and the other end is detachably connected to the front chest-attaching member 14 on the other side. Other detachable connection schemes may also be included, and are not limited thereto.

[0040] The elastic sheet 1 is made of silicone. Silicone is elastic, suitable for 3D printing, and is not prone to allergies when worn for a long time. In some possible embodiments, the thickness of the elastic sheet 1 is thickened in the area with the greatest deformation during the posture correction process to increase the elasticity. The area with the greatest deformation includes the scapula fitting part 13 close to the spine, the middle area of ​​the transition part 12, and the connection position with the external elastic part 2. The position connected to the external elastic part 2 is thickened because this position is easily damaged, and the durability of the product is improved by thickening.

[0041] The elastic sheet 1 itself is elastic. In order to adapt to the human body, the elastic sheet 1 forms a corresponding pulling structure, and the elastic sheet 1 is elastic. The neck support 11 provides a fit to the neck. When posture problems such as forward neck tilt and round shoulders and hunchback occur, the elastic sheet 1 is pulled, generating an elastic force that pulls the neck support 11 and acts on the neck support 11, thereby forcing the person to lift the neck and avoid posture problems. Due to the elasticity of the elastic sheet 1 itself, the neck support 11 can be deformed when applying force to the orthopedic object, and the surface area of ​​the neck support 11 is increased, reducing the pressure on the front of the neck and improving the user experience.

[0042] The transition portion 12 fits with the shoulder, and when the shoulder shrugs, the transition portion 12 is stretched, thereby generating elastic force, which will counteract the above posture. In addition, the transition portion 12 connects the neck support 11 and the shoulder blade fitting portion 13, and is used to transmit the pulling force when the posture changes.

[0043] The shoulder blade contact part 13 is used to build tension and is also the main source of elastic force. By analyzing the body posture, whether the neck is tilted forward or the shoulders are rounded and hunched, the shoulder blade will bulge backward relative to the healthy body posture, so that the elastic sheet 1 at the shoulder blade is stretched, generating elastic force, thereby building tension, and pulling the front neck and / or shoulder blade of the orthopedic object by transmitting force, so that the orthopedic object can restore its normal body posture.

[0044] The front-extending chest-adhering part 14 is connected to the external elastic part 2, so that the elastic sheet 1 and the external elastic part 2 form an elastic system connected end to end. The entire elastic system is saddle-shaped, and the lateral tension of the front neck and chest is balanced with the longitudinal tension of the back. Since the elastic sheet 1 is designed according to the body shape of the orthotic object, it fits the human body as closely as possible. Therefore, when the body shape of the orthotic object is unhealthy, the orthosis can intervene and apply elastic force to force the orthotic object to restore a healthy body shape.

[0045] The cervical vertebra orthosis of this embodiment also includes a method for producing the cervical vertebra orthosis of the embodiment.

[0046] A method for preparing a cervical vertebra orthosis, used for preparing the cervical vertebra orthosis as described above, the preparation method comprising: Step 1: Perform 3D scanning on the orthopedic object to obtain the position of each feature point and measure the length of the line connecting the corresponding feature points; Step 2: Import the characteristic points and their connecting lines obtained in step 1 into the modeling software to adjust the corresponding size of the cervical orthosis to form a corresponding digital model; In some embodiments, the modeling software has preset sample models, including male and female models, which are selected according to needs, and the aforementioned feature points and adjacent lines are imported into the sample model to modify the shape of the sample model, and then the corresponding size of the cervical orthosis is generated according to the sample model; Step 3: Perform 3D printing according to the digital model to form the elastic sheet 1; Step 4: Install the external elastic member 2 on the elastic sheet 1; Step 4: Wear the finished product on the orthopedic subject and adjust it according to the subjective feelings of the orthopedic subject and the operator's assessment of the body shape of the orthopedic subject.

[0047] The model is taken to obtain various characteristic points and various dimension data, and then the model is built based on the data and 3D printing is performed, so as to provide the corresponding elastic sheet 1 in a personalized manner, so as to fit the body surface of the orthopedic object. Then the model is adjusted while being worn to improve the wearing experience.

[0048] The adjustment in step 4 includes adjusting the length of the external elastic member 2 and changing the elastic coefficient by adjusting the material.

[0049] In summary, the orthosis prepared by this method has the advantages of stable structure and high comfort.
