Telescopic funnel chest correction device and preparation method thereof

Abstract

The invention relates to a medical orthopedic appliance, in particular to a telescopic funnel chest correction device and a preparation method thereof. The correction device comprises a shell and a sucker which are connected in a sealed manner; and a folding structure is arranged at the local position of the sucker side wall and used for increasing the deformation amount of the sucker side wall atthe local position and enlarging the telescopic movement range of the sucker side wall at the local position. According to the correction device, the folding structure is arranged at the local position of the side wall of the suction cup, and the folding structure has high telescopic performance, so that the correction device can generate proper deformation quantity at the concave position corresponding to the thorax, the correction effect is optimized, and the wearing comfort of the correction device is improved.

Description

technical field [0001] The invention relates to a medical orthopedic device, in particular to a retractable pectus excavatum correction device and a preparation method. Background technique [0002] Pectus excavatum is one of the common chest wall deformities in infants and young children. It generally refers to the deformity of the sternum, costal cartilage, and some ribs sunken to the dorsal side, forming a funnel shape; funnel chest can compress the heart and lungs in the chest cavity, and even cause heart displacement. Therefore, the early correction of pectus excavatum has become an important issue in the development and growth of children. [0003] Existing pectus excavatum correction devices are generally negative pressure devices with suction cups, which apply a certain value of suction to the depressed area through the suction cups to correct the distortion of the chest depression. Among them, most of the suction cups are made of soft materials such as medical rubb...

AI Technical Summary

Problems solved by technology

[0004] Some patients have very uneven depth of thoracic depression and need custom-made correction devices; and according to the specific situation of pectus excavatum to be corrected, some depression positions require a large amount of deformation of the correction device, so that the correction effect can be optimal

However, in the existing negative pressure device with a suction cup for correction, although soft materials such as rubber or silica gel have certain elasticity, the scope of expansion and contraction brought by the soft material itself has relatively large limitations and cannot meet the requirements. The orthodontic device requires a large amount of deformation in part of the concave position
