Description

Technical Field

[0001] The application relates to physical therapy equipment, and in particular to a cervical fixator. Background Art

[0002] People who work with their heads down for a long time are prone to cervical problems. As an important medical auxiliary device, the cervical fixator provides stable support and protection for the cervical spine by limiting the movement of the neck to promote recovery and reduce the risk of further injury. However, when using the cervical fixator, you need to pay attention to choosing the right size and model to ensure that the fixator can fit the neck. However, there are only a few models of cervical fixators, such as large, medium and small. When setting the model, samples are taken from most users to set it, which is suitable for most people, but not for everyone. Users can only buy the model and it is more suitable for the user. In other words, even with the same model, some users will fit better, while some users will not fit enough. This affects the use effect. People's necks are different in length and thickness. Therefore, a cervical fixator that can adjust the length, thickness and thickness of the neck in an overall way is needed. But there is no such product on the market at present.

[0003] For manufacturers, different models of cervical fixators require different molds. The more models there are, the more users can benefit. However, for manufacturers, the more molds are needed, the higher the production cost. Therefore, from the perspective of manufacturers, the most ideal state is that only one model can meet the needs of most people. For users, they only need to choose one model to save the cost of selection. However, there is no such product on the current market, so this product is urgently needed to meet the market demand.

[0087] like Figure 1 to Figure 5 As shown, the cervical vertebra fixing device of the present invention includes an adjustment platform 20, and the adjustment platform 20 further has a wearing cavity 24. The wearing cavity 24 is for a user to wear the adjustment platform 20 on the neck of the user so that the adjustment platform 20 surrounds the neck of the user. The wearing cavity 24 further defines a wearing port 241 for the user to wear the adjustment platform 20 from the wearing port 241. When the user wears the adjustment platform 20 on the neck of the user, the adjustment platform 20 can be adjusted to adapt to the neck of the user. Specifically, the adjustment platform 20 adjusts the width of the wearing cavity 24 to adapt to the width of the neck of the user, thereby fixing the neck of the user. . The cervical vertebra fixing device of the present invention further includes a back neck support portion 10, and the back neck support portion 10 is detachably connected to the adjustment platform 20. After the user wears the adjustment platform 20 on the neck of the user, the back neck support portion 10 is fitted to the back of the neck of the user, and then the back neck support portion 10 is fixed to the adjustment platform 20. That is, the back neck support part 10 fits the back of the user's neck to provide support for the back of the user's neck, and also further fixes the user's neck. After the back neck support part 10 is fixed to the user's neck, the adjustment platform 20 and the back neck support part 10 fix the user's neck. In a preferred embodiment of the present invention, two sides of the back neck support part 10 are detachably connected to two sides of the adjustment platform 20 through two adjustment straps 21.

[0088] The neck of the user has a certain length. Therefore, in the present application, the adjustment of the width of the neck of the user adopts the adjustment of the upper neck and the lower neck of the user respectively. In a preferred embodiment of the present application, the upper neck of the user is adjusted by adjusting the width of the upper jaw of the user. The top of the adjustment platform 20 provides the adjustment of the upper neck of the user by adjusting the width of the lower jaw of the user. The bottom of the adjustment platform 20 provides the width adjustment of the lower neck of the user. By adjusting the width of the upper neck of the user and the width of the lower neck of the user respectively, the overall adjustment of the width of the neck of the user is achieved. Further, the adjustment platform 20 is respectively adjusted to the upper neck of the user and the lower neck of the user, so as to adapt to more types of necks of the user. For example, in some special cases, the upper neck of the user is wider than the lower neck of the user, or the lower neck of the user is wider than the upper neck of the user. That is to say, the adjustment platform 20 of a preferred embodiment of the present application can be applied to the situation where the width of the upper neck of the user is inconsistent with the width of the lower neck of the user. Furthermore, when the top of the adjustment platform 20 is adjusted to reduce the width, the bottom of the adjustment platform 20 is also adjusted to reduce the width.

[0089] The adjustment platform 20 further provides adjustment for the angle of the lower jaw. After the angle of the lower jaw of the user is adjusted, the adjustment platform 20 further provides adjustment in the vertical direction so that the neck of the user is located in a suitable position. The adjustment platform 20 provides fixation for the neck of the user at the suitable position and further provides traction. In a preferred embodiment of the present invention, the suitable position is that the lower jaw of the user is slightly tilted upward. The tilting angle of the lower jaw of the user is adjusted by the adjustment platform 20 so that the lower jaw of the user reaches a suitable position. Then, the vertical position is adjusted by the adjustment platform 20 so that the neck of the user is supported and further pulled in a suitable position. It is worth mentioning that most users work with their heads down. Therefore, a slight tilting of the lower jaw is conducive to the extension of the cervical spine and the restoration of the natural arch. Then, the adjustment platform 20 is adjusted in the vertical section direction to fix the user in a stretched posture, thereby supporting the neck of the user. Further, the effect of pulling the neck of the user can be achieved. It is worth mentioning that in order to make the adjustment platform 20 support the neck of the user in a suitable position when adjusting the vertical direction. The adjustment platform 20 provides a buffer structure so that the adjustment platform 20 can be adjusted to a suitable position to support the neck of the user, and the user feels comfortable during the adjustment process.

[0090] The adjustment platform 20 further includes an adjustable base 21, two adjustment devices 22 and a chin support device 23. The two adjustment devices 22 are respectively installed on both sides of the adjustable base 21. The chin support device 23 is adjustably connected to the two adjustment devices 22. Specifically, the bottoms of the two adjustment devices 22 are respectively installed on both sides of the adjustable base 21. The tops of the two adjustment devices 22 are respectively connected to both sides of the chin support device 23. The middle part of the adjustable base 21 defines the wearing cavity 24. The chin support device 23 is arranged at the top of the adjustment platform 20. The adjustable base 21 is arranged at the bottom of the adjustment platform 20. The chin support device 23 provides horizontal adjustment to adapt to the width of the user's chin. The adjustable base 21 provides horizontal adjustment to adapt to the width of the lower neck of the user. When the chin support device 23 is adjusted to reduce the width of the chin support device 23, the adjustable base 21 moves toward the user's neck as the chin support device 23 moves, so as to reduce the width of the adjustable base 21. Specifically, when the chin support device 23 is adjusted to reduce the width, the chin support device 23 moves closer to the user's neck, so as to drive the two adjustment devices 22 to move closer to the user's neck, thereby making the adjustable base 21 move closer to the user's neck and reducing the width of the adjustable base 21.

[0091] In a preferred embodiment of the present invention, after the adjustment platform 20 is worn on the neck of the user, the adjustable base 21 extends from the shoulder of the user to the chest of the user. Preferably, the adjustable base 21 extends toward the back of the user. The adjustable base 21 can fit the back of the user. The tops of the two adjustment devices 22 are respectively and adjustably connected to the two sides of the chin support device 23. Preferably, the ends of the two ends of the chin support device 23 are respectively and adjustably mounted on the tops of the two adjustment devices 22. The angle of the chin support device 23 is adjusted by the two adjustment devices 22, so that the user can adjust the slight upward tilt of the chin to make the cervical spine in a comfortable posture. Preferably, the chin support device 23 adjusts the angle of the chin of the user in a rotating manner. After the chin of the user is in a comfortable posture, the two adjustment devices 22 lock the chin support device 23 respectively to limit the rotation of the chin support device 23. It is worth mentioning that when the two adjusting devices 22 continue to adjust in the vertical direction, the two sides of the adjustable base 21 slightly move away from the user's neck to form a buffer space 25 between the user's neck and the adjusting device 23. The formation of the buffer space 25, on the one hand, facilitates the adjusting device 23 to adjust the chin support device 23 to a suitable position, and on the other hand, makes the user feel comfortable during the adjustment to the suitable position. However, the existing cervical vertebra traction device lacks the setting of the buffer space, so that the user's neck is not adjusted to a suitable position, but can only be in a sub-suitable position. The reason why the existing cervical vertebra traction device can only be adjusted in a sub-suitable position is that the existing cervical vertebra traction device fits tightly with the user's neck and lacks the buffer space, so that the two adjusting devices 23 fit tightly with the user's neck skin during the adjustment from the sub-suitable position to the suitable position. On the one hand, the close fit with the user's skin increases the resistance of the adjusting device 23, and on the other hand, it also makes the user's neck feel strongly uncomfortable or even painful. Therefore, when using the existing cervical traction device, the adjustment is stopped only after it is adjusted to a sub-suitable position. Using the existing cervical traction device at a sub-suitable position reduces the use effect of the existing cervical traction device and fails to achieve the expected effect. The cervical fixation device of the present invention is provided with a buffer space 25 to reduce the friction of the two adjustment devices 23 on the user's neck skin, thereby facilitating adjustment from a sub-suitable position to a suitable position and improving the user experience. The user feels comfortable during the adjustment process. Preferably, after adjusting to the suitable position, the two sides of the adjustable base 21 move closer to the user's neck to fit the user's neck.

[0103] The following describes the adjustment system using a user's wearing process. The adjustment platform 20 is worn on the user's neck. During the wearing process, the user's neck first contacts the adjustable base 21. If the user's neck is relatively wide, the two shoulder supports 211 move away from the user's neck. The adjustment portion 212 changes accordingly to adapt to the movement of the two shoulder supports 211. In a preferred embodiment of the present invention, the adjustment portion 212 increases the distance between the two shoulder supports 211 by rotating. When the user's neck moves to the two adjustment devices 22, if the user's neck can continue to move forward, the user's chin can move to the chin support device 23 and be supported by the chin support device 23. If the user's neck is blocked by the two adjustment devices 22 and cannot move forward, the width of the chin support device 23 needs to be adjusted so that the user's neck can continue to move toward the chin support device 23. In a preferred embodiment of the present invention, the length of the two adjustment belts 23222 is extended respectively by rotating the adjustment knob 23221, so that the neck of the user can continue to move toward the chin support device 23. When the chin of the user is supported by the chin support device 23, the user can adjust the chin support device 23 to make the chin support device 23 fit the chin of the user. Specifically, the distance between the two side support members 231 is shortened by rotating the adjustment knob 23221 to move the two adjustment belts 23222 respectively, so that the two side support members 231 and the chin adjustment member 232 fit the chin of the user. It is worth mentioning that in the process of adjusting the chin support device 22 to fit the chin of the user, the two side support members 231 respectively guide the two adjustment devices 22 to move in the direction of fitting the neck of the user, thereby driving the two shoulder support members 211 to move in the direction of fitting the neck of the user.

[0104] If the chin support device 22 fails to support the user's neck due to the short neck of the user, the two adjustment devices 22 are respectively adjusted by operating the two knobs 2211 to lower the height of the chin support device 23. In addition, the angle limiting end 22234 can enter the rotating part 2222 by pressing the pressing end 22233. The chin support device 23 is adjusted to rotate downward so that the user's chin is supported by the chin support device 23. If the user's neck is long, the chin support device 23 is raised by the two adjustment devices 22. The user further increases the adjustment height by adjusting the upward tilt angle of the chin support device 23 to better suit the length of the neck.
