[0002] A cervical collar is a medical device typically used to brace and stabilize the neck, providing support and protection.

[0003] The main functions of a cervical collar include:

[0004] Support and immobilization: When the neck is injured or in a state that requires stable support, a cervical collar can provide support and immobilization to prevent excessive neck movement and reduce the risk of further injury. This is very important for the rehabilitation of neck fractures, sprains, strains or other injuries.

[0005] Relieve Neck Pressure: For some conditions, such as cervical spondylosis, tight neck muscles, or inflammatory diseases, a cervical collar can relieve pressure on the neck, reducing pain and discomfort.

[0006] Postural Support: For situations where proper posture is important, such as sleeping, a cervical collar can provide additional support to help maintain proper alignment of the neck and spine.

[0007] Treatment and rehabilitation: In some cases, such as during rehabilitation after a neck injury, a cervical collar may be used as part of treatment to help restore neck function and prevent further injury.

[0008] The angle adjustment device of the chin support of the existing neck support is complicated to operate, usually requiring two hands to adjust, and in an emergency, the neck support needs to be disassembled, and the complicated adjustment method wastes a lot of time.
