Description

Telescopic funnel chest correction device and preparation method

Technical Field

The invention relates to a medical orthopedic appliance, in particular to a telescopic funnel chest correction device and a preparation method thereof.

Background

The funnel chest is one of common chest wall deformities of infants, generally refers to the deformity that the sternum, costal cartilage and partial ribs are sunken towards the back side to form a funnel shape; the funnel chest may press the heart, lungs in the chest cavity and even cause the heart to shift. Therefore, the funnel chest is corrected early, which becomes an important problem in the development and growth process of children.

The existing funnel chest correction device is generally a negative pressure device with a sucker, and the sucker applies suction with a certain numerical value to a depressed area so as to correct the depressed distortion of the chest. Wherein, the sucking disc is mostly made of soft materials such as medical rubber or silica gel.

Some patients have very uneven depths of the thoracic depressions and require custom-made corrective devices; and according to the specific situation that the funnel chest needs to be corrected, some sunken positions require that the correcting device has a larger deformation amount, so that the correcting effect can be optimal. However, although the existing negative pressure device with a suction cup for correction has certain elasticity, the flexible movement range of the existing negative pressure device only caused by the soft material has larger limitation, and the requirement that the correction device has larger deformation amount at a part of concave positions cannot be met.

Disclosure of Invention

In order to solve the technical problems in the prior art, the invention provides the telescopic funnel chest correction device and the preparation method thereof.

On one hand, the device of the invention is realized by adopting the following technical scheme: the telescopic funnel chest correction device comprises a shell and a sucker which are connected in a sealing manner; the folding structure is arranged at the local position of the side wall of the sucker and used for increasing the deformation amount of the side wall of the sucker at the local position and expanding the telescopic moving range of the side wall of the sucker at the local position.

In a preferred embodiment of the present invention, the folding structure comprises a plurality of connected folding units having a V-shaped cross section, each folding unit comprises two folding edges, the two folding edges intersect to form a vertex of the folding unit, and two adjacent folding units are connected by an end of the folding edge.

In one embodiment of the invention, the folding structures are provided with at least one, and when two or more folding structures are provided, each folding structure is located in a different local area of the side wall of the suction cup.

In another aspect, the invention provides a method of making a retractable funnel chest correction device, comprising the steps of:

firstly, obtaining the contour line of a thoracic funnel region according to body surface data, and carrying out reverse design through the contour line to obtain the shape of a shell of the correction device;

reversely designing the shape of the sucker according to the edge of the shell; the height of the unfolded part of the sucker is selected, a first space is reserved at the upper end of the sucker, a second space is reserved at the lower end of the sucker, and the part between the first space and the second space is folded to form a folding structure.

Compared with the prior art, the invention has the following advantages and beneficial effects:

1. the folding structure is arranged at the local position of the side wall of the sucker, and has good telescopic performance and larger deformation amount, so that the local position of the side wall of the sucker where the folding structure is arranged is variable in height, the height variable range is larger, and the requirement that the correcting device has larger deformation amount at a part of sunken positions is met.

2. The folding structure is only arranged at the local position of the side wall of the sucker, so that the sucker is locally folded, and the attachment degree with the skin of a human body is not affected.

3. With the lapse of correction time, the depth of the depressed area of the thorax will change gradually, the flexible range of motion of the sucking disc part of the existing corrective device is limited, when the depth of the depressed area of the thorax changes to a certain stage, the patient has to change the corrective device; the folding structure can bring a larger deformation amount, so the invention can adapt to the depth change of the depressed area of the thorax to a larger extent, has longer service life when being worn and avoids the trouble of frequently replacing the correcting device.

Detailed Description

The present invention will be described in further detail with reference to examples and drawings, but the embodiments of the present invention are not limited thereto.

Examples

As shown in figures 1-5, the funnel chest correction device of the present invention comprises a housing 1 and a suction cup 2, wherein the housing comprises a top portion and a rim extending downward from the top portion, the suction cup is provided with a contact seam, and the rim of the housing is embedded into the contact seam of the suction cup, so that the housing and the suction cup are hermetically connected. In addition, an exhaust valve 11 and a pressure display screen 12 are arranged on the top of the shell; the suction cup 2 is made of soft materials and can be comfortably and hermetically adsorbed on the surface of the skin of the thorax.

The folding structure 3 is arranged at the local position of the side wall of the sucker 2 and used for increasing the deformation amount of the side wall of the sucker at the local position and expanding the telescopic moving range of the side wall of the sucker at the local position. The section of the folding structure is in a broken line shape, the folding structure comprises a plurality of connected folding units 31 with V-shaped cross sections, each folding unit comprises two folding edges, the two folding edges are intersected to form the top point of the folding unit, and two adjacent folding units are connected through the tail ends of the folding edges.
