Description

Technical Field

[0001] This invention relates to the field of medical technology, specifically to a single-finger trainer for scar-induced deformed fingers. Background Technology

[0002] Existing hand rehabilitation trainers provide holistic rehabilitation exercises for the entire hand. However, in clinical practice, it has been found that they cannot individually adjust and extend the fingers. This is because the range of motion and pain levels vary from finger to finger after a burn, requiring differentiated rehabilitation training. Currently used single-finger rehabilitation methods include splints and finger supports. Children with severe finger deformities may undergo surgical correction, but postoperative functional exercises are still necessary. Therefore, considering the varying range of motion in each finger after a burn, a single-finger trainer for scar-related deformities is proposed. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a single-finger trainer for scar-related deformed fingers, which has the advantage of enabling individual finger training and solves the problems of the prior art.

[0004] The present invention provides a single-finger trainer for scar-induced deformed fingers, comprising: a basic training component and a finger sleeve for wrapping the basic training component;

[0005] The basic training component includes two symmetrically arranged support plates. Each support plate has three adjustment plates corresponding to the three segments of the finger bones. The length of the adjustment plates can be adjusted according to the different lengths of the finger bones. The corresponding adjustment plates in the two support plates are connected by a spacing adjustment unit. The spacing adjustment unit can change the spacing between the two support plates to adapt to fingers of different thicknesses.

[0006] The adjusting plates in the support plate are connected by elastic elements.

[0007] In some embodiments, the adjusting plate includes an inner plate and an outer plate. The outer side of the inner plate is provided with a sliding groove, and the inner wall of the sliding groove is provided with a positioning groove. The inner wall of the outer plate is provided with a sliding strip, and the sliding strip is provided with positioning teeth that are adapted to the positioning groove. The sliding strip can move up and down inside the sliding groove, causing the positioning teeth to disengage or be inserted into the positioning groove.

[0008] In some embodiments, the spacing adjustment unit includes a spacing adjustment spring and a telescopic sleeve. The spacing adjustment spring is installed on the top of the inner plate corresponding to the two support plates, and the telescopic sleeve is installed on the top of the outer plate corresponding to the two support plates.

[0009] In some embodiments, the finger sleeve is cylindrical, with an observation hole at one end near the fingertip, an opening at the other end, and a connecting component on the side of the finger sleeve near the fingertip.

[0010] In some embodiments, the device also includes a palm sleeve worn on the palm of the hand, and a rigid mounting plate is fixedly connected to the back of the palm sleeve, and a training enhancement component is mounted on the back of the mounting plate.

[0011] In some embodiments, the training enhancement component includes three training cables respectively connected to three adjustment plates, each training cable having an adjustment member for adjusting its length, and each training cable having a training member for enhancing training at its end, the training member being mounted on a mounting plate.

[0012] In some embodiments, the adjusting component includes a winding screw, the surface of which is fixedly connected to a winding reel;

[0013] The surface of the telescopic sleeve is fitted with a connecting pipe for connecting the winding screw.

[0014] The finger sleeve has an opening on the side near the back of the finger for maneuvering the connecting tube.

[0015] In some embodiments, the training component includes a housing, an adjusting spring is provided inside the housing, and an adjusting screw for changing the elastic force of the adjusting spring is provided at one end of the housing;

[0016] The end of the training cable passes through the outer shell and the adjusting spring and is fixedly connected to a movable block, which is in contact with the end of the adjusting spring.

[0017] In some embodiments, a rope adjustment assembly is also installed on the back of the mounting plate. The rope adjustment assembly includes a slide rail, a slider is provided on the top of the slide rail, a guide ring for guiding the training rope is provided on the slider, a pin is movably provided on the slider, and a pin hole adapted to the pin is provided on the slide rail.

[0018] In some embodiments, the training component is mounted on a mounting plate via a rotating plate, the rotating plate being hinged to the mounting plate on the side near the finger sleeve, and a pin for limiting the rotating plate is mounted on the mounting plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The present invention allows the adjustment plate in the basic training component to be adjusted to accommodate knuckles of different lengths, that is, it can be adapted to fingers of different lengths. The setting of the spacing adjustment unit can change the spacing between the two support plates in the basic training component, thereby adapting it to fingers of different thicknesses. The setting of the elastic element between the two adjustment plates allows the initial training of the fingers to be achieved through the deformation of the elastic element. That is, the device can be used on different fingers.

[0021] 2. This invention, through the setting of three training cords and three training components corresponding to the three phalanges of the fingers in the training enhancement component, can apply additional force to the muscles near each phalange individually. By adjusting the adjustment screw in the training component to change the elasticity of the adjustment spring, it can train different contracted single fingers and can also perform targeted exercises according to the contractures of different joints of the fingers.

[0022] 3. The present invention uses a mounting plate to install the training component, which allows the training component to rotate synchronously with the mounting plate. When pain is felt during finger training, it indicates that the traction force is too large. At this time, simply removing the pin to contact the limit of the rotating plate can quickly release the traction force of the training enhancement component, thus improving the safety of use.

[0040] The following drawings will disclose several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details are not intended to limit the invention. That is, in some embodiments of the invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0041] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0042] Example 1:

[0043] Please see Figures 1-6 The present invention provides a single-finger trainer for scar deformed fingers, including a basic training component 3. The basic training component 3 includes two symmetrically arranged support plates. Each support plate has three adjustment plates 31 corresponding to the three segments of the finger. The length of the adjustment plates 31 can be adjusted according to the different lengths of the finger bones. The corresponding adjustment plates 31 in the two support plates are connected by a spacing adjustment unit 33. The spacing adjustment unit 33 can change the spacing between the two support plates to adapt to fingers of different thicknesses.

[0044] The adjusting plates 31 in the support plate are connected by elastic elements 32. The elastic elements 32 can be torsion springs, springs, rubber rods or other structures that can limit the distance between the adjusting plates 31, bend and have elasticity.

[0045] In this embodiment:

[0046] The length of the adjustment plate 31 in the basic training component 3 can be adjusted to adapt to different lengths of knuckles, that is, it can be adapted to fingers of different lengths. The setting of the spacing adjustment unit 33 can change the spacing between the two support plates in the basic training component 3, so as to adapt to the use of fingers of different thicknesses. The setting of the elastic element 32 between the two adjustment plates 31 can achieve the initial training of fingers through the deformation of the elastic element 32.

[0047] As a further description of the above embodiments, each of the adjusting plates 31 includes an inner plate 311 and an outer plate 312. The outer side of the inner plate 311 is provided with a sliding groove 313, and the inner wall of the sliding groove 313 is provided with a positioning groove 314. The inner wall of the outer plate 312 is provided with a sliding strip 315, and the sliding strip 315 is provided with a positioning tooth 316 that is adapted to the positioning groove 314. The sliding strip 315 can move up and down inside the sliding groove 313, causing the positioning tooth 316 to disengage or be inserted into the positioning groove 314.

[0048] The length of the adjusting plate 31 is adjusted by the outer plate 312 carrying the slider 315 and the positioning tooth 316 sliding on the slide groove 313 of the inner plate 311. This allows the positioning tooth 316 to disengage from the positioning groove 314, meaning that the slider 315 and the positioning tooth 316 on the outer plate 312 can move freely inside the slide groove 313, thereby changing the length of the adjusting plate 31 to accommodate fingers of different lengths.

[0049] As a further description of the above embodiment, each of the two inner plates 311 located at the fingertip is fixedly connected with two limiting pieces 34 for fitting with the fingertip. The setting of the limiting pieces 34 can provide initial positioning for the inner plates 311 when the adjusting plate 31 in the support plate is adjusted, so as to prevent the inner plates 311 from moving on both sides of the finger, which would make it inconvenient for the outer plate 312 to move on the inner plates 311.

[0050] As a further description of the above embodiment, the spacing adjustment unit 33 includes a spacing adjustment spring 331 and a telescopic sleeve 332. The spacing adjustment spring 331 is installed on the top of the inner plate 311 correspondingly provided in the two support plates, and the telescopic sleeve 332 is installed on the top of the outer plate 312 correspondingly provided in the two support plates.

[0051] In the above embodiment, the outer plate 312 needs to move upward outside the inner plate 311. That is, the adjusting spring 331 and the telescopic sleeve 332 in the spacing adjustment unit 33 can only be installed on the top of the inner plate 311 and the top of the outer plate 312 respectively, so as to avoid restricting the upward movement of the outer plate 312.

[0052] Since the spacing adjustment unit 33 is only installed on the top of the adjustment plate 31 in the above description, that is, there is no restriction below the adjustment plate 31, the basic training component 3 cannot be installed on the finger. Therefore, for the above structure, we can set the finger sleeve 2 on the surface of the basic training component 3 so that the basic training component 3 can be stably installed on the finger.

[0053] Please see Figure 5 , Figure 6 As a further description of the above embodiment, the finger sleeve 2 is cylindrical and has an observation hole 23 at one end near the fingertip. The other end of the finger sleeve 2 has an opening. A connecting component 22 is provided on the side of the finger sleeve 2 near the finger pad. The connecting component 22 can be a pull cord or a zipper.

[0054] In this embodiment, when in use: the basic training component 3 and the finger sleeve 2 are worn inside the finger sleeve 2. When the connecting part 22 of the finger sleeve 2 is a pull cord, the wearing method is as follows:

[0055] The first method is the basic wearing method, suitable for first-time users of the device. First, you need to unfasten the connecting part 22 on the finger sleeve 2 to open it. Then, position the two support plates on either side of the finger or on the back and pad of the finger (e.g., ...). Figure 1 and Figure 2 Then, the length of the adjustment plate 31 is changed so that the elastic element 32 is located at the joint of the finger. In this embodiment, the preferred elastic unit is a torsion spring. After all the lengths of the adjustment plates 31 and the elastic elements 32 are in the corresponding positions of the fingers, the finger sleeve 2 is tightened by pulling the rope.

[0056] The tightening of the finger sleeve 2 can cause the adjusting spring 331 and telescopic sleeve 332 in the spacing adjustment unit 33 to retract, thereby clamping and fixing the finger, which facilitates the transmission of force during subsequent training.

[0057] The second type is an advanced wearing method, which is suitable for situations where the device has already been worn and there is no need to adjust the adjustment plate 31. The finger sleeve 2 is placed on the finger with its opening facing outwards, and then the connecting part 22 is used to secure the finger sleeve 2. This method does not require completely untying the pull cord; it is sufficient to loosen the pull cord, which saves wearing time.

[0058] When the connecting part 22 of the finger sleeve 2 is a zipper, the finger sleeve 2 is made of elastic material, and the two support plates are worn by clamping the sides of the fingers, the wearing method is as follows:

[0059] The first basic wearing method is the same as the wearing method when the connecting component 22 is a pull cord;

[0060] The second advanced wearing method differs from the wearing method when the connecting part 22 is a pull cord. After the zipper is opened, there is no obstruction below the two support plates, and it can be worn by fastening it on the fingers from above. Compared with the wearing method when the connecting part 22 is a pull cord, it has a more convenient effect and further facilitates the switching of the basic training component 3 on different fingers.

[0061] In this embodiment, considering that the support plate may cause poor blood circulation when clamping the finger, two different clamping methods are proposed. One method clamps both sides of the finger, which can be fastened to the finger from top to bottom for easy wearing. The other method clamps the back and pad of the finger with the two support plates to reduce pressure on blood vessels and improve blood circulation. In addition, the observation hole 23 on the finger sleeve 2 can be used to observe the fingertip to judge the blood circulation and avoid secondary finger ischemia damage caused by prolonged wearing.

[0062] Example 2:

[0063] Please see Figure 5 - Figure 10As a further improvement to Embodiment 1, unlike Embodiment 1, the scar deformed finger single finger trainer of the present invention also includes a palm sleeve 1 worn on the palm, and a rigid mounting plate 6 is fixedly connected to the back of the palm sleeve 1. A training enhancement component 4 is also installed on the back of the mounting plate 6.

[0064] The training enhancement component 4 includes three training cables 42 that are respectively connected to three adjustment plates 31. The training cables 42 are provided with adjustment components 43 for adjusting the length. The end of the training cable 42 is provided with a training component 41 for enhancing training. The training component 41 is mounted on the mounting plate 6.

[0065] This embodiment is used based on implementation one, and its function is to provide additional traction to the basic training component 3, thereby enhancing finger training.

[0066] As a further description of the above embodiment, the adjusting component 43 includes a take-up screw 431, the surface of which is fixedly connected to a take-up reel 432; the back of the basic training component 3 is equipped with a connecting pipe 35 for connecting the take-up screw 431 (see [link]). Figure 7 , Figure 8 and Figure 9 The finger sleeve 2 has an actuation hole 21 on the side near the back of the finger for the movement of the connecting tube 35.

[0067] As a further description of the above embodiment, the training component 41 includes a housing 411, an adjusting spring 412 is provided inside the housing 411, and an adjusting screw 413 for changing the elastic force of the adjusting spring 412 is provided at one end of the housing 411. By rotating the adjusting screw 413, the length of the spring can be changed, thereby achieving the effect of changing the traction force. At the same time, a scale can be provided on the surface of the adjusting screw 413 to better control the traction force.

[0068] The end of the training cable 42 passes through the outer shell 411 and the adjusting spring 412 and is fixedly connected to a movable block, which is in contact with the end of the adjusting spring 412.

[0069] As a further description of the above embodiment, a rope adjustment assembly 5 is also installed on the back of the mounting plate 6. The rope adjustment assembly 5 includes a slide rail 51, a slider 52 is provided on the top of the slide rail 51, a guide ring 54 for guiding the training rope 42 is provided on the slider 52, a pin 53 is movably provided on the slider 52, and a pin hole adapted to the pin 53 is provided on the slide rail 51. By changing the position of the guide ring 54, the training rope 42 can be kept directly above the back of the finger, thereby achieving the effect of traction on the finger.

[0070] When using this embodiment:

[0071] You need to wear palm gloves first;

[0072] Then, wear the finger cot 2 and the basic training component 3 according to the scheme in Example 1;

[0073] Next, slide the slider 52 in the adjustment cord assembly 5 on the slide rail 51 until it corresponds to the finger on the finger sleeve 2, and then insert the pin 53 into the corresponding pin hole in the slide rail 51 to lock it in place.

[0074] Then, connect the winding screw 431 in the adjusting component 43 of the connecting training cable 42 to the connecting tube 35 in the basic training component 3 by threading, and change the length of the training cable 42 by rotating the winding training cable 42.

[0075] When in use, by setting up three training cords 42 and three training components 41 in the training enhancement component 4 corresponding to the three phalanges of the finger, extra force can be applied to the muscles near each phalange individually. The elasticity of the adjusting spring 412 can be changed by adjusting screw 413 in the training component 41, so that it can train different contracted single fingers, and can also perform targeted exercises according to the contractures of different joints of the finger.

[0076] Example 3:

[0077] Please see Figure 9 The training component 41 is mounted on the mounting plate 6 via a rotating plate 7. The side of the rotating plate 7 closest to the finger sleeve 2 is hinged to the mounting plate 6. A pin 8 is mounted on the mounting plate 6 to limit the rotating plate 7.

[0078] In this embodiment, when pain is felt during finger training, it indicates that the traction force is too large. At this time, simply pull out the pin 8 to limit the contact with the rotating plate 7, and the training component 41 can be rotated through the rotating plate 7, thereby loosening the training cable 42. This design can quickly release the traction force of the training reinforcement component 4 when the training traction intensity is too large, improving the safety of use.

[0079] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
