[0026] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] See also Figures 1 to 4 The head-lowering auxiliary fixation device of the present invention includes a neck support component 10 and a head limiting component 20.

[0030] The cervical collar assembly 10 includes a cervical collar frame 11 and a lifting frame 12 fixed on the cervical collar frame 11, wherein the lifting frame 12 is aligned with the back of the patient's neck;

[0031] The head limiting assembly 20 includes a lifting block 21 provided on the lifting frame 12, and an inclined pressure plate 22 fixed on the lifting block 21. The inclined pressure plate 22 is provided with a pillow 23 for pressing the back of the patient's head. The pillow 23 can be raised or lowered by adjusting the lifting frame 12, thereby adjusting the patient's head-lowering angle.

[0032] The tilted pillow 23 presses against the back of the patient's head, keeping the patient in a head-down position. This minimizes the impact on the patient's range of motion and eliminates the need for the patient to deliberately maintain a head-down position. This allows the patient to speak, drink, eat, and see, while also providing a better rehabilitation experience and alleviating the burden on the patient. Furthermore, the pillow 23 can be raised or lowered by adjusting the lifting frame 12, allowing the head-down angle to be adaptively adjusted according to the patient's needs, avoiding discomfort caused by excessive head-down angles restricted by the pillow 23.

[0033] See Figure 2 The neck bracket 11 is in a semi-enclosed arc shape and has a certain elasticity. In actual application, the medical staff can open the neck bracket 11 with a little force to expand its opening, and then put the neck bracket 11 around the patient's neck to serve as a support for the head limit assembly 20.

[0034] For further information, see Figure 1 and Figure 2 The neck brace 11 is connected to shoulder braces 32 on opposite sides via connecting rods 31. These shoulder braces 32 are provided with straps 33. The shoulder braces 32 are supported on the patient's shoulders and then secured around the patient's armpits via the straps 33. As can be appreciated, the design of the shoulder braces 32 distributes pressure that might otherwise be concentrated on the neck to the patient's shoulders and armpits, reducing the burden on the neck and helping to alleviate neck muscle tension and pain.

[0035] In addition, in order to reduce the discomfort caused by wearing the shoulder bracket 32 ​​and the neck bracket 11 for a long time, a flexible pad 40 can be provided on the inner edge of the neck bracket 11 and the lower surface of the shoulder bracket 32 ​​for cushioning, thereby improving the wearing comfort of the patient. Figure 2 .

[0036] See Figure 2 The lifting frame 12 includes a fixed base 121 and at least two telescopic rods 122 that are slidably connected to the fixed base 121. The lifting block 21 is disposed at one end of the telescopic rods 122 away from the fixed base 121. Specifically, the fixed base 121 is L-shaped as a whole, with a short arm portion fixedly connected to the neck bracket 11 and a long arm portion slidably connected to the telescopic rods 122. The telescopic rods 122 can slide relative to the fixed base 121, thereby achieving the raising or lowering of the lifting block 21.

[0037] Furthermore, the outer wall of the fixed base 121 is penetrated by at least one first threaded hole corresponding to the telescopic rod 122, and a first bolt 123 is threadedly connected to the first threaded hole. It can be understood that the first bolt 123 is used to tighten the surface of the telescopic rod 122, limit the extension and contraction of the telescopic rod 122, and ensure that the pillow 23 remains in a specific position. Specifically, in actual application, when the user needs to adjust the height of the pillow 23, first loosen the first bolt 123, and then adjust the extension and contraction distance of the telescopic rod 122. When the height of the pillow 23 is adjusted to the appropriate position, tighten the first bolt 123, and the first bolt 123 is used to tighten the surface of the telescopic rod 122 to form a strong friction force, thereby firmly locking the telescopic rod 122 and keeping the pillow 23 at a specific height.

[0038] Specifically, in this embodiment, the number of telescopic rods 122 is 5, of which 4 telescopic rods 122 are located at the 4 diagonal points of the upper end surface of the fixed base 121, and 1 telescopic rod 122 is located at the center point of the upper end surface of the fixed base 121, and the first bolt 123 is aligned with the telescopic rod 122 at the center point.

[0039] See Figure 2 The lifting block 21 is provided with a curved plate 50 at the position of the back of the patient's head. The arrangement of the curved plate 50 can better fit the skeletal curvature of the back of the wearer's head, which not only improves the wearer's stability but also improves the wearer's comfort.

[0040] See Figure 1 、 Figure 3 and Figure 4 , a support rod 61 is detachably connected to each of the two connecting rods 31, and a mandibular support 62 is connected between the two supporting rods 61. It can be understood that when the neck brace 11 is worn, the mandibular support 62 can be assembled on the connecting rod 31 to support the patient's mandible, thereby reducing the pressure on the neck caused by lowering the head for a long time.

[0041] Specifically, the support rod 61 includes a connecting section 611, a curved section 612, and an adjustment section 613, which are sequentially connected to the mandibular support 62. The connecting rod 31 is provided with a through-hole 63 extending in a first predetermined direction. The connecting rod 31 is provided with a second threaded hole 64 extending in a second predetermined direction and inserted into the through-hole 63. A second bolt 65 is threadedly connected to the second threaded hole 64. It is understood that the second bolt 65 is used to tighten against the surface of the adjustment section 613, limiting its extension and contraction, thereby ensuring that the mandibular support 62 remains in a specific position. Specifically, in actual use, when assembling the mandibular support 62, the adjustment section 613 can be aligned and inserted into the through-hole 63 on the connecting rod 31. The extension and contraction distance of the adjustment section 613 can then be adjusted based on the patient's head-down angle to adjust the position of the mandibular support 62. After ensuring that the mandibular support 62 supports the patient's mandible, the second bolt 65 is tightened to secure it.

[0042] In addition, it should be noted that, in this embodiment, the bending angle of the bending section 612 can be adjusted as needed and is not limited to 90° in this embodiment. This embodiment is only an example and not a limitation.

[0043] Furthermore, the mandibular support 62 is rotatably connected between the two connecting sections 611. This allows the mandibular support 62 to be adjusted according to the patient's specific mandibular contour, thereby better adapting to the patient's mandibular contour and greatly improving the patient's comfort during wearing.

[0044] In summary, the head-lowering auxiliary fixation device in the above-mentioned embodiment of the present invention presses the back of the patient's head through the tilted pillow 23 to keep the patient in a head-lowering state, which has little impact on the patient's range of movement and does not require the patient to subjectively maintain a head-lowering position. While satisfying the patient's daily life such as speaking, drinking water, eating, and seeing things, it provides the patient with a better rehabilitation experience and reduces the burden on the patient.
