Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a dental treatment chair with restraint function. Background Technology

[0002] During dental treatment, patients (especially children, people with special needs, or those with anxiety disorders) often experience problems such as involuntary movement, sudden standing, or limb swaying due to pain, fear, or physical limitations. This can lead to soft tissue injury from treatment instruments, decreased operational precision, or even medical accidents. While traditional dental chairs have basic functions such as position adjustment and lighting assistance, they still have significant shortcomings in terms of patient restraint.

[0003] Currently, the most common restraint methods in clinical practice are manual assisted fixation, which relies on medical staff or family members to manually press on the patient's limbs. This not only consumes human resources, but uneven force application may also exacerbate patient resistance and even lead to medical disputes. Therefore, there is an urgent need to develop a dental treatment chair with restraint functions. Utility Model Content
