Description

Technical Field

[0001] The present invention belongs to the technical field of Achilles tendon rehabilitation devices, and particularly relates to a flexible water bag type adjustable Achilles tendon shoe. Background Art

[0002] When people suffer from ankle injuries or Achilles tendon ruptures, during the later recovery period, a brace needs to be fixed to prevent re-injury and secondary rupture of the Achilles tendon; during the recovery period after Achilles tendon surgery, the Achilles tendon needs to be relaxed first. Generally, the ankle joint is plantar flexed with the toes pointing downwards. At this time, the angle between the toes and the calf is greater than 90 degrees. Initially, the angle between the toes and the calf is about 120°, and then an appropriate angle is increased every once in a while until it is adjusted to 90°. Traditional rehabilitation braces are integrally formed without an angle adjustment structure, but a heel pad is placed under the heel; when using such a brace, the calves and soles of Achilles tendon injury patients cannot fit well with the brace, resulting in poor comfort and stability, and it cannot be applied to different Achilles tendon patients, and the recovery effect is poor. Summary of the Invention

[0003] In view of this, the present invention provides a flexible water bag type adjustable Achilles tendon shoe to solve the above problems.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Embodiment 1

[0029] Refer to the attached Figures 1-4 and Figure 7, the present invention provides a flexible water bag type adjustable Achilles tendon shoe, comprising: a shoe body 10, a flexible water bag 20, and a liquid discharge mechanism 30. The flexible water bag 20 is disposed at the rear heel of the shoe body 10. The material of the flexible water bag 20 is silica gel or TPU, having good flexibility, pressure resistance, and biocompatibility. The flexible water bag 20 needs to withstand the dynamic pressure of the foot (such as about 40 - 60 KPa of pressure during walking), so the thickness of the flexible water bag 20 is set to 1.5 - 2 mm. Reinforcing ribs 21 are also provided at the key stress-bearing parts of the flexible water bag 20 corresponding to the rear heel. The upper surface of the flexible water bag 20 is in an arc structure of plantar flexion of the heel, which is adapted to the heel to reduce stress concentration. The surface of the flexible water bag 20 is covered with high-density memory cotton or an elastic gel pad to further disperse the pressure and avoid the risk of pressure sores caused by direct contact with hard materials. The liquid discharge mechanism 30 is connected to the flexible water bag 20 through a pipeline, and the liquid in the flexible water bag 20 is discharged through the liquid discharge mechanism 30 to adjust the height of the flexible water bag 20, which can quickly and conveniently adjust the ankle angle according to needs, having the advantages of good stability and simple structure, and can achieve a small range of angle adjustment, meeting the different needs of users.

[0030] The liquid discharge mechanism 30 includes a liquid discharge pipe 31, a connecting rod 32, and a piston 33. The piston 33 is installed at one end of the connecting rod 32, and the piston 33 extends into the liquid discharge pipe 31. The piston 33 is movably connected to the inner wall of the liquid discharge pipe 31, and the liquid discharge pipe 31 is connected to the flexible water bag 20 through a pipeline. Preferably, threads are provided between the side wall of the piston 33 and the inner wall of the liquid discharge pipe 31, and the piston 33 is threadedly connected to the inner wall of the liquid discharge pipe 31. Manually rotate the connecting rod 32, and the piston 33 is threadedly connected to the inner wall of the liquid discharge pipe 31. Driving the connecting rod 32 to rotate will drive the piston 33 to precisely move on the inner wall of the liquid discharge pipe 31, ensuring that the distance corresponding to each rotation of the piston 33 is controllable. Preferably, the pitch of the piston 33 can be set to 0.5 mm / turn.

[0031] A transparent window 11 is provided on the side wall of the rear heel of the shoe body 10, and a transparent area is provided on the rear side wall of the flexible water bag 20. The transparent window 11 corresponds to the transparent area in position. A scale is provided on the transparent window 11, and the remaining liquid volume in the flexible water bag 20 is displayed through the transparent window 11 and the scale on the transparent window 11, facilitating users and doctors to observe the adjustment progress.

[0032] A flexible water bag type adjustable Achilles tendon shoe further includes a feedback mechanism 50. The feedback mechanism 50 includes a feedback cavity 51, a rotating rod 52, a spring 53 and a steel ball 54. The feedback cavity 51 is threadedly connected to the inlet of the drain pipe 31. The rotating rod 52 is located inside the feedback cavity 51, and both ends are slidably connected to the inner wall of the feedback cavity 51. The connecting rod 32 is a polygonal rod. Avoidance holes 511 are provided in two cross-sections of the feedback cavity 51. A through hole adapted to the connecting rod 32 is provided on the rotating rod 52. The connecting rod 32 passes through the avoidance holes 511 and the through hole, and the connecting rod 32 is slidably connected to the rotating rod 52 through the through hole; a groove 521 is provided at one end of the rotating rod 52. The spring 53 is located in the groove 521, one end is fixedly connected to the bottom wall of the groove 521, and the other end is fixedly connected to the steel ball 54. The steel ball 54 is slidably connected to the groove 521. A feedback groove 512 is provided on the inner wall of the periphery of the feedback cavity 51, and the feedback groove 512 is adapted to the steel ball 54. While the connecting rod 32 drives the piston 33 to move in the drain pipe 31, the connecting rod 32 also moves along its own axis. The rotation of the connecting rod 32 drives the rotating rod 52 to rotate in the feedback cavity 51 and slide with the rotating rod 52 at the same time; under the action of the elastic force of the spring 53, the steel ball 54 slides on the inner wall of the periphery of the feedback cavity 51. When passing through the feedback groove 512, the steel ball 54 enters the feedback groove 512. Continuing to rotate the connecting rod 32, the steel ball 54 slides out of the feedback groove 512, so that every time the piston 33 rotates one circle, the steel ball 54 makes a sound when passing through the feedback groove 512, enhancing the operation confirmation.

[0033] A flexible water bag type adjustable Achilles tendon shoe further includes a pair of auxiliary air bags 60. The auxiliary air bags 60 are arranged on the inner wall of the rear end of the shoe body 10, on both sides of the Achilles tendon surgical incision, to prevent the shoe body 10 from pressing on the Achilles tendon surgical incision.

[0034] In Embodiment 1, the drain mechanism 30 does not need to be installed on the side of the shoe body 10. When adjusting the height of the flexible water bag 20, the drain pipe 31 is communicated with the internal flexible water bag 20 through the side wall of the shoe body 10, and then the height of the flexible water bag 20 is adjusted through the drain mechanism 30. When the height of the flexible water bag 20 is not adjusted, the drain mechanism 30 does not follow the shoe body 10.

[0035] Embodiment 2

[0036] Referring to the appendix Figures 1-2 and Figures 5-7 which is different from Embodiment 1, a flexible water bag type adjustable Achilles tendon shoe further includes a brace 40. The brace 40 is installed on the side wall of the shoe body 10, and the drain mechanism 30 is detachably installed on the brace 40. Specifically, the brace 40 can be a magic tape or a detachable plastic bracket. Through the brace 40, the drain mechanism 30 is installed on the side wall of the shoe body 10 and follows the shoe body 10, and the height of the flexible water bag 20 can be adjusted at any time.
