Abstract

The invention discloses an adjustable structure of an orthopedic helmet. The adjustable structure is arranged at the opening and closing position of the orthopedic helmet, the opening and closing position of the orthopedic helmet is partially overlapped, the adjustable structure comprises a ratchet belt and a ratchet buckle matched with the ratchet belt, wherein the ratchet belt comprises an arc-shaped bottom plate and ratchets, the inner wall of the bottom plate is matched with the outer wall face of the orthopedic helmet in an attached mode, the bottom plate comprises a fixed plate and a ratchet plate, the fixed plate is fixed at the rear half part of the opening and closing position of the orthopedic helmet, the ratchet plate is provided with triangular ratchets, and the pitch of the ratchets is 0.5-3mm; and the ratchet buckle comprises two fixedplates fixed to the front half part of the orthopedic helmet, an inverted-U-shaped installation plate is connected between the two fixed plates, a penetrating hole is formed between the installation plate and the orthopedic helmet, the free end of the ratchet belt penetrates through the penetrating hole, a base is installed on a top plate of the installation plate, the base is connected with a pawl inclining towards the ratchet belt, the elastic deformation amount of the pawl is 50%-60% of the height of the three ratchets, and the pawl comprises a blocking tooth valve and a blocking tooth head which is connected with the free end of the blocking tooth valve and is inserted and clamped between every two adjacent triangular ratchets.

Description

technical field [0001] The invention relates to an adjustable structure of an orthopedic helmet, which is mainly used to realize precise adjustment in the growth process of the head circumference of infants with deformed head. Background technique [0002] Orthopedic helmets are mainly used for infants with cranial deformities. Between 3 months and 18 months after birth, due to different degrees of abnormalities in the anteroposterior or lateral positions of the infant's skull, misalignment or Restricted, affect the development of multiple regions of the brain, and even affect the development of cranial orthopedics for neurodevelopmental issues. Literature research found that head deformity can also affect the development and function of children's oral and maxillofacial region, otolaryngology and head and neck muscles. The incidence of cranial deformities in children was 22% when they were 7 weeks old and 21% when they were 2 years old. Evidence of cranial dysplasia in ad...

AI Technical Summary

Problems solved by technology

[0004] For the problem of infantile head deformity, there are currently two kinds of orthopedic products at home and abroad: the first is a special shape pillow, which is used for infants to sleep on the pillow, but the orthopedic method is completely dependent on the shape of the pillow, and the orthopedic method is passive and cannot be used. Avoid the sleeping position of infants and young children; the second is the orthopedic helmet provided by professional institutions, which is mainly used for children with head shape problems of 4 to 15 months old infants. It belongs to the intervention treatment of growth and development and is widely used

[0005] The structure of the traditional orthopedic helmet is to adjust the Velcro or buckle on one side of the temporal bone, which is completely adjusted by personal experience and lacks quantitative standards.
