Description

Technical Field

[0001] This invention relates to the field of medical care products technology, and more specifically, to a corrective device for developmental dysplasia of the hip in children. Background Technology

[0002] Developmental dysplasia of the hip (DDH) is a general term for congenital or developmental abnormalities of the hip joint during infancy and childhood, including acetabular dysplasia, dislocation, and subluxation. Early symptoms include asymmetry of the gluteal folds, asymmetry of the thigh folds, and unequal leg length. The incidence rate is generally considered to be 0.1%–0.3%, but comprehensive and authoritative statistics are lacking in China. It is more common in girls, with a male-to-female ratio of 1:6, and 20% of affected children have a family history. The cause is still unclear, but it may be related to breech delivery, joint laxity, and family history.

[0003] For developmental dysplasia of the hip (DDH), early diagnosis and treatment are crucial; the older the patient, the worse the outcome. Infants and young children primarily undergo conservative treatment involving closed reduction, such as wearing special socks, Pavlik harnesses, or plaster casts to spread and stabilize the thighs, keeping them in an abducted position and forcing the femoral head as close to the acetabulum as possible. For patients over 3 years of age, surgical treatment is necessary.

[0004] Statistics show that children who receive treatment during infancy have the best prognosis, and their hip joints can fully recover in the future. Therefore, for newborns, it is important to detect and treat these conditions as early as possible.

[0005] For infants and young children, using specially designed socks is ineffective because they are too soft, like clothing, and fail to properly support the thighs, resulting in poor treatment outcomes. Using Pavlik harnesses, with their numerous straps around the neck, chest, calves, and feet, causes discomfort and marks on the skin. Plaster casts, which need to be custom-made to fit the infant's size, are not universally applicable and cannot be adjusted according to the patient's hip dysplasia recovery progress, further hindering their effectiveness.

[0006] Therefore, the tools used in existing conservative treatments need to be improved and optimized. Summary of the Invention

[0031] The beneficial effects of this invention are:

[0032] Firstly, the pediatric developmental dysplasia of the hip correction device provided by this invention, in specific implementation, on the one hand, with the child lying flat, the first inverted V-shaped wrist support facilitates the support of the child's left knee and wrist, and the second inverted V-shaped wrist support facilitates the support of the child's right knee and wrist. The telescopic adjustment component, when connected between the first and second inverted V-shaped wrist supports, facilitates the fixation of the first and second inverted V-shaped wrist supports, thereby allowing the child's legs to be spread outwards and fixed, which is beneficial for the correction and treatment of developmental dysplasia of the hip. On the other hand, in use, the child's thighs are only supported by the first and second inverted V-shaped wrist supports, making it comfortable to use. Unlike traditional Pavlik braces, this invention prevents discomfort caused by constriction on the child's thighs and other body parts. Furthermore, the adjustable telescopic mechanism allows for adjustable spacing between the first and second inverted V-shaped wrist supports, facilitating adaptation to different child sizes and lower body dimensions. The spacing can also be adjusted based on the child's hip dysplasia recovery progress, resulting in excellent performance. This invention is suitable for children with varying lower body sizes, offering strong adaptability and versatility, thus demonstrating high practicality and effectiveness.

[0033] Secondly, in this technical solution, on the one hand, the first protective barrier is designed to cover the child's left leg and prevent it from slipping off the first inverted V-shaped wrist support, and the second protective barrier is designed to cover the child's right leg and prevent it from slipping off the second inverted V-shaped wrist support, thus improving the reliability of the invention. On the other hand, the first soft padding is designed to support the child's left leg comfortably, and the second soft padding is designed to support the child's right leg comfortably. Furthermore, when the first fastening strap A and the first fastening strap B are used to fasten the child's left leg, the first inverted V-shaped wrist support can be fixed to the outside of the child's left leg, and when the second fastening strap A and the second fastening strap B are used to fasten the child's right leg, the second inverted V-shaped wrist support can be fixed to the outside of the child's right leg, making it convenient for adults to hold the child. Therefore, the effectiveness of the invention can be effectively improved.

[0034] Thirdly, in this embodiment, on the one hand, the first tie strap A, the first tie strap B, the second tie strap A, and the second tie strap B all have a certain degree of elasticity, making their length adjustable and the tightness of binding the child's leg adjustable. Furthermore, the first tie strap A, the first tie strap B, the second tie strap A, and the second tie strap B are all fixed by male and female Velcro fasteners, making operation convenient and quick. On the other hand, since the telescopic adjustment component includes a first telescopic adjustment component and a second telescopic adjustment component; when adjusting the length of the first telescopic adjustment component, the distance between the front side of the first inverted V-shaped wrist rest and the front side of the second inverted V-shaped wrist rest is adjustable; when adjusting the length of the second telescopic adjustment component... When adjusting the length of the adjustable component, the distance between the rear sides of the first inverted V-shaped wrist support and the rear sides of the second inverted V-shaped wrist support is adjustable. This ensures good flexibility of the telescopic adjustment component. Furthermore, since the connecting parts at both ends of the first telescopic adjustment component and the second telescopic adjustment component are connected to the first and second inverted V-shaped wrist supports respectively using universal joint structures, the invention does not hinder the child's walking when fixed to the child's leg. At the same time, since the first inverted V-shaped wrist support, the second inverted V-shaped wrist support, and the telescopic adjustment component are all made of hard plastic, the invention is lightweight and easy to wear and move around in, thus achieving the best performance of the invention.

[0047] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, so as to more clearly and intuitively understand the inventive essence of the present invention.

[0048] Combination Figure 1 As shown;

[0049] The present invention provides a pediatric developmental dysplasia of the hip correction device 1000, which includes a first inverted V-shaped wrist support 10 suitable for supporting the left knee and wrist of a child, a second inverted V-shaped wrist support 20 suitable for supporting the right knee and wrist of a child, and a telescopic adjustment member for adjusting the distance between the first inverted V-shaped wrist support 10 and the second inverted V-shaped wrist support 20 to open up the left and right thighs of the child.

[0050] The telescopic adjustment member is connected between the first inverted V-shaped wrist rest 10 and the second inverted V-shaped wrist rest 20.

[0051] Based on the above, it is clear that the pediatric developmental dysplasia of the hip correction device 1000 provided by the present invention is mainly for use by pediatric patients lying flat in specific implementation.

[0052] On the one hand, when the child is lying flat, the first inverted V-shaped wrist support 10 can easily support the child's left knee and wrist, and the second inverted V-shaped wrist support 20 can easily support the child's right knee and wrist. When the telescopic adjustment component is connected between the first inverted V-shaped wrist support 10 and the second inverted V-shaped wrist support 20, it makes it easy to fix the first inverted V-shaped wrist support 10 and the second inverted V-shaped wrist support 20, thereby allowing the child's legs to be spread outward and fixed, which is beneficial to the corrective treatment of developmental dysplasia of the hip.

[0053] On the other hand, when using this invention, the child's two thighs are only supported by the first inverted V-shaped wrist support 10 and the second inverted V-shaped wrist support 20, making it comfortable to use. Unlike the traditional Pavlik harness, the child's two thighs and other parts of the body will not be constricted by force, which would cause discomfort.

[0054] Furthermore, since the telescopic adjustment component itself has an adjustable telescopic length, the distance between the first inverted V-shaped wrist support 10 and the second inverted V-shaped wrist support 20 is adjustable, making it easy to adapt the distance between the first inverted V-shaped wrist support 10 and the second inverted V-shaped wrist support 20 to a suitable size for use according to the size of the child's lower body.

[0055] Furthermore, the spacing between the two devices can be adjusted according to the degree of recovery of the child's hip dysplasia during use, resulting in excellent performance. For example, if the examination shows that the child's hip dysplasia is gradually improving, the spacing can be increased until the femoral head is forced to move as far as possible into the acetabulum. This invention also makes it suitable for children with different lower body sizes, making it highly adaptable and versatile. For example, if the child has a larger lower body, i.e., thicker thighs, the spacing between the first inverted V-shaped wrist support 10 and the second inverted V-shaped wrist support 20 can be reduced.

[0056] Furthermore, this invention is highly practical and has good performance.

[0057] It should be emphasized that in this technical solution, the two sides of the first inverted V-shaped wrist support 10 protrude upward to form a first guard 101 for covering the child's left leg; the two sides of the second inverted V-shaped wrist support 20 protrude upward to form a second guard 201 for covering the child's right leg.

[0058] Thus, the first protective barrier 101 conveniently covers the child's left leg to prevent it from slipping off the first inverted V-shaped wrist support 10, and the second protective barrier 201 conveniently covers the child's right leg to prevent it from slipping off the second inverted V-shaped wrist support 20, making the invention highly reliable in use.

[0059] Furthermore, in this technical solution, a first soft pad 102 is adhered to the upper surface of the first inverted V-shaped wrist rest 10; a second soft pad 202 is adhered to the upper surface of the second inverted V-shaped wrist rest 20.

[0060] Thus, the first soft pad 102 is designed to support the child's left leg comfortably, and the second soft pad 202 is designed to support the child's right leg comfortably.

[0061] Furthermore, in this embodiment, the first inverted V-shaped wrist support 10 has a first tethering strap A103 for tightening the child's left leg along the front side upward on the left side, and a first tethering strap B104 for tightening the child's left leg along the rear side upward on the left side; the second inverted V-shaped wrist support 20 has a second tethering strap A203 for tightening the child's left leg along the front side upward on the right side, and a second tethering strap B204 for tightening the child's left leg along the rear side upward on the right side.

[0062] Thus, when the first fastening strap A103 and the first fastening strap B104 are used to fasten the left leg of the child patient, the first inverted V-shaped wrist support 10 can be fixed to the outside of the child patient's left leg. When the second fastening strap A203 and the second fastening strap B204 are used to fasten the right leg of the child patient, the second inverted V-shaped wrist support 20 can be fixed to the outside of the child patient's right leg, making it convenient for adults to hold the child patient.

[0063] Therefore, the effectiveness of the present invention can be effectively improved.

[0064] Preferably, in this technical solution, the first fastening strap A103 includes a first elastic band A1031 connected to the front side of the left edge of the first inverted V-shaped wrist support 10 and a first male Velcro strap A1032 connected to the upper end of the first elastic band A1031; the first fastening strap B104 includes a first elastic band B1041 connected to the rear side of the left edge of the first inverted V-shaped wrist support 10 and a first male Velcro strap B1042 connected to the upper end of the first elastic band B1041.

[0065] A first female hook and loop fastener A105 is attached to the front side of the bottom surface of the first inverted V-shaped wrist rest 10 for attaching the first male hook and loop fastener A1032; a first female hook and loop fastener B106 is attached to the rear side of the bottom surface of the first inverted V-shaped wrist rest 10 for attaching the first male hook and loop fastener B1042.

[0066] Furthermore, the second fastening strap A203 includes a second elastic band A2031 connected to the front side of the right edge of the second inverted V-shaped wrist support 20 and a second male Velcro strap A2032 connected to the upper end of the second elastic band A2031; the second fastening strap B204 includes a second elastic band B2041 connected to the rear side of the right edge of the second inverted V-shaped wrist support 20 and a second male Velcro strap B2042 connected to the upper end of the second elastic band B2041.

[0067] A second female hook and loop fastener A205 is attached to the front side of the bottom surface of the second inverted V-shaped wrist rest 20 for attaching the second male hook and loop fastener A2032; a second female hook and loop fastener B206 is attached to the rear side of the bottom surface of the second inverted V-shaped wrist rest 20 for attaching the second male hook and loop fastener B2042.

[0068] Thus, the first fastening strap A103, the first fastening strap B104, the second fastening strap A203 and the second fastening strap B204 all have a certain degree of elasticity, making their length adjustable and the tightness of binding the child's legs adjustable. Specifically, the tightness can be adjusted according to the size of the child's legs.

[0069] Furthermore, the first fastening strap A103, the first fastening strap B104, the second fastening strap A203, and the second fastening strap B204 are all fixed by means of male and female Velcro fasteners, making operation convenient and quick.

[0070] Furthermore, the effectiveness of the present invention can be further improved.

[0071] It should be added that, in specific implementation, in this technical solution, the telescopic adjustment component includes a first telescopic adjustment component 30 and a second telescopic adjustment component 40;

[0072] Wherein, the first telescopic adjustment member 30 is connected between the front side of the first inverted V-shaped wrist support 10 and the front side of the second inverted V-shaped wrist support 20; the second telescopic adjustment member 40 is connected between the rear side of the first inverted V-shaped wrist support 10 and the rear side of the second inverted V-shaped wrist support 20.

[0073] When the length of the first telescopic adjustment member 30 is adjusted, the distance between the front side of the first inverted V-shaped wrist rest 10 and the front side of the second inverted V-shaped wrist rest 20 is adjustable;

[0074] When the length of the second telescopic adjustment member 40 is adjusted, the distance between the rear side of the first inverted V-shaped wrist support 10 and the rear side of the second inverted V-shaped wrist support 20 is adjustable.

[0075] Thus, the telescopic adjustment component has good adjustment flexibility, allowing for flexible adjustment of the spread between the child's thighs.

[0076] Specifically, in this technical solution, the first telescopic adjustment component 30 includes a first ball joint A301, a first universal ball joint A302, a first locking bolt A303, a first ball joint B304, a first universal ball joint B305, a first locking bolt B306, a first sleeve 307, a first telescopic rod 308, and a first locking bolt C309.

This makes it possible to fix the present invention to the legs of children without hindering their walking. That is, the present invention can also be used for children's walking.

[0087] Therefore, in conjunction with the above description, it can be understood that the present invention can be used by children lying down, by adults holding them, or by children walking, making it highly compatible.

[0088] Furthermore, in this specific implementation, the first inverted V-shaped wrist rest 10, the second inverted V-shaped wrist rest 20, and the telescopic adjustment component are all made of hard plastic.
