Description

Adjustable fixed splint for children

Technical Field

The utility model relates to the field of medical equipment, and more specifically to an adjustable fixing splint for children.

Background Art

Fracture refers to the interruption of the integrity or continuity of a bone, which is prone to occur in the elderly and children. Therefore, in addition to adult fixation splints, pediatrics also needs to have fixation splints for children.

China Patent Authorization Announcement No.: CN219501295U, provides an adjustable fixation splint. This patent sets a telescopic device and an adjustment device to adjust the length of the fixation splint. It is suitable for patients with a larger range of limb fractures, or can be adjusted according to pediatric patients of different ages and heights. It is suitable for children of all ages, and there is no need to replace different fixation splints according to different body shapes and ages. It is convenient and practical.
