Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pediatric oral spacer. Background technique [0002] In pediatrics, when examining or treating a child, the child's mouth needs to be opened for medical staff to operate. However, because children are prone to fear and resistance during the treatment and examination, they usually keep their mouths tightly closed, which is inconvenient for treatment and examination. Therefore, when performing pediatric oral treatment and examination, it is necessary to assist medical staff to support the patient's oral cavity through an external device. [0003] The existing spreaders are all hand-held, and children can easily avoid them by shaking their heads, which affects the opening effect. Conventional mechanical aids usually use mobile components to force open the mouth, which can easily cause harm to children. [0004] To this end, the present application proposes a new pediatri...
