Description

Technical Field

[0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a tension training rehabilitation device for burned fingers. Background Art

[0002] Burns are not uncommon in life. After a finger is burned, because the fingers are affected by joint immobilization, bandaging and flexibility, if exercise is not performed at an appropriate time period, it will be detrimental to the recovery of normal function. At present, exercises for burned fingers are mainly divided into passive exercises, fine movements and strength exercises. Passive exercises mainly refer to using the power of others or using normal fingers to help the affected limb move. Fine movements are mainly through putting on cups, pushing rolling barrels, picking up beads, etc. to gradually restore the flexibility of various small joints of the hand. Strength exercises are mainly carried out with the help of equipment.

[0003] In the prior art, most of the rehabilitation exercises for fingers are based on weight-bearing flexion and extension exercises such as springs or elastic ropes. Although finger rehabilitation exercises can be performed, there are many inconveniences when following the doctor's advice to gradually control the weight-bearing intensity. In order to provide different elastic weights when flexing and extending the fingers, it is necessary to frequently use tools to adjust the initial position of each spring or elastic rope, which is extremely inconvenient. Especially for patients with finger burns, it is basically difficult to complete the above-mentioned adjustment operations independently.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-9 The present invention provides a technical solution: a tension training rehabilitation device for burned fingers, comprising a self-adhesive wristband 1, and also comprising:

[0039] A mounting plate 11, which is disposed on the side of the self-adhesive wristband 1; and

[0040] Four movable elastic units 2 are sequentially mounted on the mounting plate 11 and are used for weight-bearing flexion and extension exercises of four fingers except the thumb; and

[0041] An active elastic unit 3 is mounted on the mounting plate 11 at a position adjacent to the movable elastic unit 2 and adjacent to the thumb; and

[0042] A linkage component 4 is used to connect the active elastic unit 3 and the four movable elastic units 2, so as to utilize the different movement distances of the active elastic unit 3 to change the initial position of the movable elastic unit 2 in real time and provide weight-bearing flexion and extension exercise for the thumb; and

[0043] The refined motion component 5 is mounted on the mounting plate 11 to provide refined motion training for the fingers.

[0044] Furthermore, it is different from the prior art. By using the active elastic unit 3, the movable elastic unit 2 and the linkage component 4, when the self-adhesive wristband 1 and the mounting plate 11 are used to perform rehabilitation exercises on the fingers, the active elastic unit 3 can be driven by the thumb to change and adjust the elastic load of the movable elastic unit 2 in real time, and the same elastic load can be provided to the thumb through force transmission, without the need for tools or help from others to adjust the finger load, thereby flexibly meeting the weight-bearing exercise use of burned fingers at various stages;

[0045] In addition, through the design of the refined action component 5, it is also possible to conveniently provide effective refined exercise for burned fingers in any place, so as to ensure high-quality exercise and rehabilitation of burned fingers through refined action and strength-bearing training.

[0046] As a technical means, the movable elastic unit 2 includes a slider 21 slidably mounted on the mounting plate 11, an elastic rope 22 is mounted on the slider 21, and a finger ring 23 is mounted at the end of the elastic rope 22. The finger rings 23 of the four movable elastic units 2 are respectively matched with four fingers except the thumb. In this way, when exercising the fingers in real time, the finger ring 23 is respectively put on each finger, and the elastic rope 22 is stretched when the fingers are flexed and extended, so as to utilize the real-time elastic force of the elastic rope 22 to provide elastic weight for the fingers, so as to provide effective strength training.

[0047] As a technical means, the active elastic unit 3 includes a slider 2 31 slidably mounted on the mounting plate 11, a pull rope 32 is mounted on the slider 2 31, and a finger ring 2 33 is mounted at the end of the pull rope 32. The inner diameter of the finger ring 2 33 is larger than the inner diameter of the finger ring 1 23 to match the thumb. When in use, it is put on the thumb like the finger ring 1 23. Different from the movable elastic unit 2, the active elastic unit 3 does not provide any weight for the thumb when the thumb moves, and only uses the thumb to provide movement.

[0048] Furthermore, slide grooves 12 that match the slider 1 21 and the slider 2 31 respectively are opened on the mounting plate 11 in sequence, and the slider 1 21 and the slider 2 31 are both I-shaped, so that they can slide arbitrarily in the slide groove 12 and cannot be separated. With such a design, the slider 1 21 and the slider 2 31 can slide stably on the mounting plate 11 and cannot be separated from the mounting plate 11, thereby ensuring the stability of the slider 1 21 and the slider 2 31.

[0049] Also as a technical means, a through hole 41 is provided on the side wall of the slide groove 12 provided with the slider 21, and the linkage component 4 includes a plurality of pull rods 42 respectively sliding through the plurality of through holes 41, one end of the pull rod 42 is connected to the slider 21 in the corresponding slide groove 12, and a synchronization rod 43 is provided on the outside of the mounting plate 11, and one end of the plurality of pull rods 42 away from the slider 21 is connected to the synchronization rod 43, and when the synchronization rod 43 moves, the initial positions of all the sliders 21 are synchronously changed, and when the initial position of the slider 21 is changed, when the finger is flexed and extended to a fixed state, the stretching degree of the elastic rope 22 will change, which means that the elastic load provided by the elastic rope 22 to the finger ring 23 has changed;

[0050] A driving member 44 is also provided on the mounting plate 11, and the driving member 44 is used to connect the slider 2 31 and the synchronization rod 43, so as to adjust the position of the synchronization rod 43 when the thumb actively pulls the slider 2 31 to change its position, and then the movement of the thumb is used to adjust the initial position of the slider 1 21. It should be noted that the different bending degrees of the thumb directly determine the size of the moving distance of the slider 1 21, that is, the flexion and extension degree of the thumb directly adjusts the size of the elastic load provided by the elastic rope 22, and there is no need to additionally adjust the operation of each elastic rope 22. The design is novel and flexible to use.

[0051] Furthermore, the driving member 44 includes a driving rod 441 mounted on the synchronization rod 43, a continuous tooth groove 442 is provided on the side of the driving rod 441, and a vertical shaft 443 is rotatably mounted on the mounting plate 11, and a gear 444 engaged with the tooth groove 442 is mounted on the vertical shaft 443;

[0052] An active rod 445 is installed on the vertical shaft 443, and a compensation rod assembly 446 is provided at the end of the active rod 445 away from the vertical shaft 443, and the active rod 445 is connected to the slider 2 31 by the compensation rod assembly 446, so that when the thumb flexes and extends to drive the slider 2 31 to move, the movement of the slider 2 31 drives the active rod 445 to rotate. However, it should be noted that under normal circumstances, the active rod 445 will change its end point position when rotating, so that its movement trajectory interferes with the movement trajectory of the slider 2 31. In this case, the design of the compensation rod assembly 446 is used to compensate for the problem of interference between the active rod 445 and the slider 2 31, to ensure stable drive when the thumb flexes and extends, and to ensure that the vertical shaft 443 drives the gear 444 to rotate when the slider 2 31 moves.

[0053] Furthermore, the compensation rod assembly 446 includes a connecting shaft 447 rotatably mounted on the active rod 445, a deflection link 448 is mounted on the connecting shaft 447, a rotating shaft 449 is provided at one end of the deflection link 448 away from the connecting shaft 447, the rotating shaft 449 is rotatably mounted on the slider 2 31, and the sum of the length dimensions of the deflection link 448 and the active rod 445 is greater than the distance dimension between the rotating shaft 449 and the vertical shaft 443. In this way, when the slider 2 31 moves, the relative deflection of the deflection link 448 and the active rod 445 can be used to compensate for the interference of the active rod 445 caused by the length problem, thereby ensuring the stable driving use of the active rod 445.

[0054] In addition, as a technical means, the refined action component 5 includes a sleeve frame 51 arranged on the mounting plate 11, and a second through hole 52 and a third through hole 53 are respectively opened on the front and rear side walls of the sleeve frame 51, and the elastic rope 22 and the pull rope 32 pass through the second through hole 52, and the driving rod 441 passes through the third through hole 53;

[0055] A partition 54 is provided in the sleeve frame 51 to divide the sleeve frame 51 into two upper and lower areas, and a cover plate 55 is hinged on the top of the sleeve frame 51 to form a storage area 56 with the partition plate 54. A plurality of balls 57 are placed in the storage area 56, and a plurality of cone sleeves 58 are also placed in the storage area 56. In this way, during actual exercise use, when only one hand of the patient is burned, the self-adhesive wristband 1 can be switched to the intact hand, and the cover plate 55 can be opened, and the patient can use it to pick up the balls 57 or the cone sleeves 58 for refined picking exercises. In addition, the affected hand can also stack the taken cone sleeves 58 to enrich the refined movements of finger exercise and ensure efficient refined exercise and rehabilitation use of burned fingers.

[0056] Furthermore, an iron sheet 541 is embedded on one side of the partition 54 near the storage area 56, and the ball 57 and the cone sleeve 58 are both made of magnetic material. Such a design can not only provide effective refined exercise, but also provide weight to the ball 58 and the cone sleeve 58 through magnetic attraction during the process of taking them, thereby further improving the refined rehabilitation exercise effect, and under the action of magnetic attraction, it can also effectively prevent the ball 57 and the cone sleeve 58 from accidentally detaching, falling and being lost.

[0057] Furthermore, a fixing seat 59 is provided on one side of the partition 54 close to the storage area 56, a screw hole 591 is provided on the fixing seat 59, and an insertion rod 592 is placed in the storage area 56, a screw 593 adapted to the screw hole 591 is provided at one end of the insertion rod 592, and the insertion rod 592 is also made of magnetic material;

[0058] The ball 57 and the cone sleeve 58 are both provided with a hole 594. Through such a design, on the basis of the ball 57 and the cone sleeve 58, more refined rehabilitation exercises for burned fingers can be further enriched and provided to enhance the rehabilitation exercise effect for burned fingers.

[0059] It should be noted that in the process of force transmission, after the elastic load of the four fingers is changed, the four fingers also provide load to the thumb. At this time, the load on the thumb is the sum of the loads of the four fingers, which means that the four fingers can easily pull the thumb to move. At this time, the long lever arm of the active rod 445 is designed to effectively balance the load on the thumb, ensuring that the thumb is not easy to move after the position is adjusted first, thereby ensuring stable rehabilitation exercise.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
