Adjustable neck protector

The present invention relates to the technical field of medical auxiliary equipment, and more particularly to an adjustable neck protector.

Cervical diseases can be roughly classified into short-term and long-term injuries. Among them, short-term injuries refer to injuries on the cervical vertebra caused by sports injuries or traffic accidents. Relatively, long-term injuries such as cervical joint degradation or long-term damage The damage caused by poor posture. For cervical injuries caused by sports injuries or traffic accidents, doctors usually use a collar to fix and restrict the movement of the patient's neck after the surgical treatment is completed to prevent secondary instability caused by instability of the cervical spine.

Referring to Figure 1, a perspective view of a conventional collar is shown. As shown in FIG. 1 , the conventional collar 1 ′ mainly includes: a lower neck sleeve 11 ′, a lower bus support 12 ′, two support units 13 ′, and an adjustment module 14 ′; The lower neck sleeve 11' includes a two-ring neck side piece 111' and a leading edge piece 112'. Further, the two supporting units 13' are respectively connected to the inner side of the two-ring neck side member 111' such that the chin supporting member 12' is disposed between the two-ring neck side members 111' through the two supporting units 13'. On the other hand, the adjustment module 14' is disposed above the leading edge member 112'.

With continued reference to Figure 1, and also to Figure 2, a front view of a conventional collar is shown. As shown in FIG. 1 and FIG. 2, the adjustment module 14' includes a receiving body 141', an upper rack 142', a lower rack 143', a gear 144', and a knob 151'. The upper rack 142 ′ and the lower rack 143 ′ are disposed opposite to each other in the accommodating body 141 ′, and the gear 144 ′ is disposed on the upper rack 142 ′ and the lower rack 143 . 'between. Further, the knob 151' is coupled to the gear 144' and exposed outside the receiving body 141'. When the collar 1' is applied, the user's chin is supported by the chin support 12', and at the same time, the gear 144' can be rotated through the knob 151' to advance the chin support according to the injury of the patient with different cervical injuries. The angle of the 12' (also known as the upper neck sleeve) is adjusted to the proper position.

The collar 1' shown in Figures 1 and 2 has the advantage of easily adjusting the upper and lower angles of the upper neck sleeve as long as the gear 144' is rotated through the knob 151'. Even so, the collar 1' exhibits the following drawbacks in practical applications: (1) The angle of the chin support 12' (also referred to as the upper neck) of the collar 1' cannot be fine-tuned. From Fig. 2, it can be clearly seen that the accuracy of the adjustment angle of the upper neck sleeve is determined by the number of teeth of the upper rack 142' and the lower rack 143'. However, because the rack with high number of teeth is expensive, the upper rack 142' and the lower rack 143' applied to the conventional collar 1' belong to the middle and low number of racks, resulting in the angle of the upper neck sleeve. Can't be fine-tuned. (2) The gear 144' of the collar 1' does not have a design to prevent retreat. As can be seen from FIG. 2, when the gear 144' is rotated clockwise, the upper rack 142' and the lower rack 143' move upward to adjust the angle of the chin support 12' (also referred to as the upper neck sleeve) upward; Conversely, when the gear 144' is rotated counterclockwise, the upper rack 142' and the lower rack 143' move downward to adjust the angle of the upper neck sleeve downward. However, since the gear 144' does not have a design for preventing the retreat, after the angle adjustment of the chin support 12' is completed, there is a possibility that the gear 144' is retracted due to factors such as external force impact or rack wear.
