Description

Technical Field

[0001] The invention relates to the technical field of inter-finger skin burns, and in particular to an inter-finger skin burn rehabilitation limiting device. Background Art

[0002] In the field of rehabilitation of skin burns between fingers, traditional rehabilitation training methods have been relatively simple.

[0003] The muscle tissue of burned fingers often atrophies to varying degrees due to trauma and long-term inactivity.

[0004] The common training method is to guide patients to perform simple finger flexion and extension activities. Most of this type of training is carried out without additional resistance.

[0005] In the non-resistance training mode, the finger muscles cannot be fully and effectively stimulated.

[0006] The growth of muscle strength depends on appropriate load stimulation, and traditional non-resistance training cannot meet this requirement, resulting in extremely slow recovery of patients' finger muscle strength and endurance.

[0007] For example, after long-term traditional rehabilitation training, many patients still have significantly insufficient finger grip strength and are unable to complete daily actions such as holding a pen or holding objects, which seriously affects their quality of life.

[0008] Moreover, the burn conditions of different patients vary greatly, with the severity of burns ranging from mild to severe. The burn sites also involve various areas between the fingers. At the same time, there are significant differences in the patients' own age, physical fitness and recovery ability.

[0009] For patients with extremely weak finger strength in the early stages of rehabilitation, if the same intensity training method as other patients is adopted, it is very likely that over-training will lead to increased pain in the injured area, worsened tissue damage, and even complications such as infection, thereby delaying the recovery process.

[0010] On the contrary, as the patient's rehabilitation stage progresses, when finger strength increases, fixed-intensity resistance-free training can no longer further stimulate muscle potential and cannot meet the patient's needs to increase muscle strength, making rehabilitation training lack of specificity.

[0011] In view of this, this application is hereby filed. Summary of the invention

[0012] The purpose of the present invention is to provide a finger skin burn rehabilitation limiting device to solve the problems raised in the above background technology.

[0017] Furthermore, a grip ring is provided at the front end of the arm sleeve, the arm sleeve is narrow at the front and wide at the back, and Velcro is provided on both sides of the rear end of the arm sleeve.

[0018] Furthermore, the arm sleeve is provided with a mounting socket, and a plurality of the mounting sockets are arranged in a linear array and distributed on the surface of the arm sleeve. The lower end of the connecting piece is connected to a mounting piece, and a straight slot is provided on the mounting piece. A rubber plug is arranged in the straight slot, and the rubber plug is adapted to the mounting socket.

[0020] Furthermore, the rotating block is connected to a connecting column, the rotating recess is fixedly connected to the connecting column, and a positioning spring is arranged between the fixed block and the connecting column.

[0021] Furthermore, a through hole is formed on the fixing block, a reinforcing column is slidably connected in the through hole, and two ends of the reinforcing column are fixedly connected to two ends of the connecting piece.

[0022] Furthermore, the finger sleeve is in a teardrop shape, and a gasket is provided on the inner side of the finger sleeve.

[0023] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the patient performs rehabilitation training, the patient needs to overcome the elastic force of the limit spring to stretch the fingers. This resistance training effectively enhances the muscle strength and endurance of the finger muscles and promotes the recovery of finger function. Compared with traditional resistance-free training, it significantly improves the rehabilitation effect and shortens the rehabilitation period. The initial elastic force coefficient of the limit spring can be changed by rotating the threaded column. The rehabilitation plan can be tailored according to the patient's rehabilitation stage and finger strength. A lower elastic force is set in the early stage of rehabilitation to avoid excessive fatigue and injury of the patient.

The connecting piece cooperates with the numerous linear array mounting sockets on the arm cuff through rubber plug blocks. The installation operation is simple and the position of the connecting piece can be flexibly adjusted according to the position of the patient's burned finger and rehabilitation needs, thereby providing a hardware foundation for personalized rehabilitation treatment and improving the accuracy of rehabilitation treatment.

[0025] In the present invention, the connecting block is rotatably connected to the connecting plate, and the slider slides on the connecting block, so that the finger cuff can adjust the position and angle in multiple dimensions to meet the needs of burned fingers in different positions and different stages of rehabilitation, ensure that the injured finger is in the best rehabilitation limit state, improve the patient's comfort and rehabilitation experience, and the convex guide groove ensures that the adjustment block slides stably to avoid dislocation or falling off; the limit spring provides resistance and plays a buffering role at the same time, preventing the patient from using excessive force to injure the injured finger, thereby ensuring the safety of rehabilitation training.

[0026] In the present invention, the scale grooves on both sides of the perforation on the back of the slider and the pointer-shaped adjustment block connecting block provide accurate quantitative indications for adjusting the elastic coefficient of the limit spring, which is convenient for medical staff and patients to make precise adjustments and ensure the scientific implementation of the rehabilitation training program.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0031] See also Figure 1-8 , the present invention provides a technical solution: A finger skin burn rehabilitation limiting device comprises an arm sleeve 1, a connecting piece 2 and a finger hanging sleeve 7, wherein a grip ring 11 is arranged at the front end of the arm sleeve 1, the arm sleeve 1 is narrow at the front and wide at the back, and Velcro is arranged at both sides of the rear end of the arm sleeve 1; The arm sleeve 1 is provided with a mounting socket 12, and a plurality of the mounting sockets 12 are arranged in a linear array and distributed on the surface of the arm sleeve 1. The lower end of the connecting piece 2 is connected to a mounting piece 21, and a straight slot 22 is provided on the mounting piece 21. A rubber plug 23 is arranged in the straight slot 22, and the rubber plug 23 is adapted to the mounting socket 12.

[0032] The arm sleeve 1 is designed to be narrow in front and wide in the back to fit the natural shape of the arm, and the Velcro on both sides of the rear end allows the patient to fix the arm sleeve 1 on the arm conveniently and firmly according to the thickness of his or her arm.

[0033] The grip ring 11 at the front end plays the function of auxiliary fixation and can be stuck in the base of the patient's palm to further assist fixation.

[0034] The connecting piece 2 is connected to the arm sleeve 1 via the mounting piece 21 below.

[0035] A rubber plug 23 is placed in the straight slot 22 on the mounting plate 21. When the connecting plate 2 needs to be installed, the rubber plug 23 is aligned with the mounting holes 12 distributed in a linear array on the surface of the arm sleeve 1 and pressed hard. The rubber plug 23 is squeezed into the mounting holes 12 by its own elastic deformation, thereby realizing the installation of the connecting plate 2 on the arm sleeve 1.

[0036] Since the number of the installation sockets 12 is large and their distribution is regular, the installation position of the connecting piece 2 on the arm cuff 1 can be flexibly adjusted according to the specific position of the patient's burned finger and rehabilitation needs.

[0037] For example, if the patient's index finger is burned, the connecting piece 2 can be installed at the corresponding mounting hole 12 close to the side of the index finger, so as to perform more accurate positioning rehabilitation on the index finger later.

[0038] The Velcro fixing method of the arm sleeve 1 and the design of being narrow in front and wide in the back can adapt to the arms of patients of different thicknesses and ages, ensuring comfort and stability of wearing.

[0039] The grip ring 11 provides convenience for the patient's daily activities, will not interfere with the recovery of the burned part of the finger, and can also assist the patient in completing some simple movements and improve the patient's ability to take care of himself.

[0040] The connecting piece 2 and the arm sleeve 1 are installed by the cooperation of the rubber plug block 23 and the installation socket 12, and the operation is simple.

[0041] The plurality of installation sockets 12 distributed in a linear array greatly improves the flexibility of the installation position of the connecting piece 2.

[0042] Whether it is a burn at different locations on the hand, or the need to adjust the position of the limit device as the wound heals during the rehabilitation process, it can be easily achieved, providing hardware support for personalized rehabilitation treatment and helping to improve the accuracy and effectiveness of rehabilitation treatment.

[0043] The rubber plug 23 has good elasticity and friction, and can fit tightly after being inserted into the mounting socket 12, ensuring that the connecting piece 2 is firmly connected to the arm sleeve 1 and will not loosen due to slight shaking or external force during the patient's daily activities, thereby ensuring the stability of the entire rehabilitation limit device during use and providing reliable support for the rehabilitation of injured fingers.

[0044] The connecting piece 2 is rotatably connected with a connecting block 3, and sliding grooves 33 are provided on both sides of the connecting block 3. Positioning blocks 34 are fixedly connected to both sides of the connecting piece 2 with a rotating ring 31. The slider 32 is slidably connected to the connecting block 3 through the positioning block 34. The top of the connecting block 3 is rotatably connected with a rotating ring 31, and the rotating ring 31 is rotatably connected to the connecting piece 2. A guide groove 35 is provided in the connecting block 3, and the adjusting block 5 is slidably connected in the guide groove 35. The guide groove 35 is in a convex shape. The two ends of the limit spring 6 are rotatably arranged between the connecting piece 2 and the adjusting block 5. A threaded column 51 is rotatably connected in the slider 32. The adjusting block 5 is threadedly connected to the threaded column 51, and the finger hanging sleeve 7 is rotatably connected to one end of the slider 32.

[0045] The connecting piece 2 and the connecting block 3 are rotatably connected via the rotating ring 31 , which enables the connecting block 3 to flexibly rotate within a certain angle range relative to the connecting piece 2 , thus providing a basis for subsequent adjustment of the position and direction of the finger hanging sleeve 7 .

[0046] The slide grooves 33 on both sides of the connecting block 3 are connected to the slider 32 via the positioning blocks 34 , and the slider 32 can slide in the slide grooves 33 , thereby ensuring the stability and accuracy of the movement of the slider 32 .

[0047] The adjusting block 5 slides in the convex guide groove 35 of the connecting block 3, and the limit spring 6 connected between the connecting piece 2 and the adjusting block 5 is in a stretched state under normal conditions, pulling up the slider 32.

[0048] When the patient performs rehabilitation training, the force generated by bending the finger overcomes the elastic force of the limit spring 6, and the slider 32 is pulled out from the connecting block 3 to complete the finger stretching action, thereby enhancing the rehabilitation training effect.

[0049] The threaded column 51 rotatably connected in the slider 32 is threadedly connected to the adjustment block 5. When the initial elastic coefficient of the limit spring 6 needs to be adjusted, the adjustment block 5 will move in the guide groove 35 due to the effect of the thread by rotating the threaded column 51.

[0050] The movement of the adjustment block 5 changes the stretching degree of the limit spring 6, thereby changing its initial elastic coefficient to meet the needs of patients at different rehabilitation training stages.

[0051] For example, in the early stage of rehabilitation, the patient's finger strength is relatively weak, and the elastic force of the limit spring 6 can be appropriately reduced; as rehabilitation progresses, the patient's finger strength increases, and the elastic force can be increased to gradually increase the difficulty of rehabilitation training.

[0052] The finger hanging sleeve 7 is rotatably connected to one end of the slider 32 , and the patient puts the injured finger into the finger hanging sleeve 7 .

[0053] When the slider 32 slides on the connecting block 3 and the connecting block 3 rotates relative to the connecting plate 2, the finger hanging sleeve 7 can move accordingly to provide appropriate limiting and support for the injured finger. At the same time, its rotating connection method can adapt to the angle changes of the finger during different movements.

[0054] By rotating the threaded column 51 to change the initial elastic coefficient of the limit spring 6, a rehabilitation training program can be customized according to the patient's rehabilitation stage and finger strength.

[0055] In the early stages of rehabilitation, lower elasticity allows patients to train easily and avoid excessive fatigue and injury; as rehabilitation progresses, the elasticity is gradually increased to continuously challenge and enhance finger muscle strength, thereby improving the pertinence and effectiveness of rehabilitation training.

[0056] When the patient is undergoing rehabilitation training, he needs to overcome the elastic force of the limit spring 6 to complete the finger extension movement. This resistance training can effectively enhance the strength and endurance of the finger muscles and promote the recovery of finger function.

[0057] Compared with traditional resistance-free rehabilitation training, this device can more significantly improve the rehabilitation effect and shorten the rehabilitation period.

[0058] The rotational connection between the connecting block 3 and the connecting sheet 2 and the sliding movement of the slider 32 on the connecting block 3 enable the position and angle of the finger hanging sleeve 7 to be adjusted in multiple dimensions.

[0059] This can well meet the needs of fingers with burns in different locations and at different stages of the rehabilitation process, ensuring that the injured fingers are always in the best rehabilitation limit state, improving the patient's comfort and rehabilitation experience.

[0060] The convex guide groove 35 ensures that the adjustment block 5 can only slide in a specific direction, thereby preventing it from being misplaced or falling off during the movement.

[0061] The limit spring 6 not only provides the resistance required for rehabilitation training, but also plays a buffering role to a certain extent, preventing the patient from causing secondary injury to the injured finger due to excessive force, thereby ensuring the safety of rehabilitation training.

[0062] Whether adjusting the threaded column 51 to change the elastic force or adjusting the positions of the connecting block 3 and the sliding block 32 , the operation is relatively simple.

[0063] Patients or medical staff can master the system without complicated training, which makes it convenient to make adjustments at any time according to actual conditions during daily rehabilitation training, thus improving the convenience and compliance of rehabilitation training.

[0064] A through hole 46 is provided on the back of the slider 32, and the adjusting block 5 connecting block 3 is slidably connected in the through hole 46. The adjusting block 5 connecting block 3 is fixedly connected to the adjusting block 5, and scale grooves 36 are provided on both sides of the through hole 46. The adjusting block 5 connecting block 3 is transparent and in the shape of a pointer.

[0065] The adjusting block 5 and the connecting block 3 are fixedly connected to the adjusting block 5 . When the adjusting block 5 moves in the guide groove 35 due to the rotation of the threaded column 51 , the connecting block 3 of the adjusting block 5 will move synchronously.

[0066] Since the adjusting block 5 connecting block 3 is slidably connected in the through hole 46 on the back of the slider 32, and its texture is transparent and in the shape of a pointer, and scale grooves 36 are provided on both sides of the through hole 46, the adjusting block 5 connecting block 3 can clearly indicate the position change of the adjusting block 5 in the guide groove 35.

[0067] By observing the corresponding scales of the adjusting block 5 and the connecting block 3 on the scale groove 36 , medical staff or patients can intuitively understand the adjustment amount brought about by the rotation of the threaded column 51 , thereby accurately grasping the adjustment of the elastic coefficient of the limit spring 6 .

[0068] The graduated groove 36 and the pointer-shaped adjusting block 5 connecting the block 3 provide accurate quantitative indication for adjusting the elastic coefficient.

[0069] During the rehabilitation training process, different stages have different resistance requirements for finger training. By reading the scale, the elastic force of the limit spring 6 can be accurately adjusted to ensure that the rehabilitation training program is strictly implemented as planned, thereby improving the scientificity and accuracy of the rehabilitation training.

[0070] For example, in the middle stage of rehabilitation, the elastic coefficient needs to be increased by a specific value. Through the scale indication, the adjustment can be completed quickly and accurately to avoid affecting the rehabilitation effect due to excessive or insufficient adjustment.

[0071] A knob 52 is disposed at the top of the slider 32 . The knob 52 is fixedly connected to the threaded column 51 . The knob 52 is hexagonal.

[0072] The knob 52 is hexagonal and fixedly connected to the top of the threaded column 51. This shape design is convenient for users to grasp and apply force, and the knob 52 can be easily turned whether it is adjusted by the patient himself or operated by medical staff.

[0073] When the knob 52 rotates, the threaded column 51 fixed thereto is driven to rotate synchronously, and then the adjustment block 5 is pushed to move in the guide groove 35 according to the threaded connection relationship, thereby adjusting the initial elastic coefficient of the limit spring 6.

[0074] The hexagonal knob 52 increases the contact area and friction with the fingers, making it easier for the user to turn it. Compared with an ordinary round button or directly turning the threaded column 51, the operation is more convenient and labor-saving.

[0075] Especially for patients with hand injuries and weak strength, they can easily turn the knob 52 to adjust the elastic force, which greatly improves the convenience of adjusting the device during rehabilitation training, enhances the patient's autonomous participation, and is conducive to the smooth progress of rehabilitation training.

[0076] Precise adjustment and convenient operation allow patients to have a better experience during rehabilitation training.

[0077] Patients can clearly understand the adjustment of their training parameters and can easily adjust them according to their own feelings and rehabilitation needs, which increases the autonomy and controllability of rehabilitation training, reduces anxiety caused by difficulties in operating the device or lack of understanding of the adjustment situation, and enhances patients' confidence and cooperation in rehabilitation treatment.

[0078] A fixed block 4 is also provided between the connecting plate 2 and the mounting plate 21. The fixed block 4 is fixedly connected to the mounting plate 21. A rotating block 41 is rotatably and slidably connected in the fixed block 4. The rotating block 41 is fixedly connected to the connecting plate 2. A fixing protrusion 44 is fixedly connected in the fixed block 4. The rotating block 41 is connected to a rotating recess 45 adapted to the fixing protrusion 44.

[0079] The rotating block 41 is connected to a connecting column 42 , the rotating recess 45 is fixedly connected to the connecting column 42 , and a positioning spring 43 is provided between the fixed block 4 and the connecting column 42 .

[0080] The fixing block 4 is provided with a through hole 46 , in which a reinforcing column 47 is slidably connected, and two ends of the reinforcing column 47 are fixedly connected to two ends of the connecting piece 2 .

[0081] The fixing block 4 is fixedly connected to the mounting plate 21 to provide basic support for the entire structure.

[0082] The rotating block 41 is rotatably and slidably connected in the fixed block 4 , and is fixed to the connecting piece 2 , so that the connecting piece 2 can rotate relative to the fixed block 4 .

[0083] The fixing protrusion 44 and the rotating recess 45 are adapted to each other. When the connecting piece 2 is rotated, the rotating recess 45 rotates along the contour of the fixing protrusion 44 , thereby changing the angle of the connecting piece 2 .

[0084] The connecting column 42 connects the rotating block 41 and the rotating recess 45 , and plays a role in stabilizing the structure during the rotation process.

[0085] The positioning spring 43 is located between the fixing block 4 and the connecting column 42. When the connecting piece 2 rotates to a certain angle, the elastic force generated by the positioning spring 43 can keep the rotating concave 45 relative to the fixing convex 44, thereby maintaining the stability of the angle of the connecting piece 2 and preventing it from shaking randomly.

[0086] A reinforcing column 47 is slidably connected to the through hole 46 on the fixing block 4 , and two ends of the reinforcing column 47 are fixedly connected to two ends of the connecting piece 2 .

[0087] During use of the device, the reinforcing column 47 can slide in a small range in the perforation 46. When the connecting piece 2 is subjected to external force (such as the patient adjusts the position of the finger to drive the connecting piece 2 to move), the reinforcing column 47 can disperse and transmit these external forces, thereby enhancing the stability of the connection between the connecting piece 2 and the fixing block 4 and preventing the connecting piece 2 from being damaged or deformed due to excessive force.

[0088] The connecting plate 2 can be adjusted at multiple angles through the rotating connection between the rotating block 41 and the fixed block 4. The angle of the connecting plate 2 can be flexibly adjusted according to the position of the patient's injured finger and the different movement requirements of rehabilitation training, providing a more suitable position and direction for the finger sling 7, thereby improving the pertinence and effectiveness of rehabilitation training.

[0089] For example, when performing fisting rehabilitation training, the connecting piece 2 can be adjusted to a suitable angle so that the finger hanging sleeve 7 can better assist the fingers to complete the movement.

[0090] The cooperation between the fixing protrusion 44, the rotating recess 45 and the positioning spring 43 ensures that the connecting piece 2 can stably maintain the position after rotating to a set angle.

[0091] During the rehabilitation training process, the patient's movements may produce certain vibrations or external forces. The stable angle of the connecting piece 2 can ensure that the position of the finger cuff 7 is always relatively fixed, providing continuous and stable limitation and support for the injured finger, which helps to improve the accuracy and safety of the rehabilitation training and avoid unnecessary interference or damage to the injured finger due to the shaking of the connecting piece 2.

[0092] The provision of the reinforcing column 47 significantly enhances the connection strength between the connecting piece 2 and the fixing block 4 .

[0093] Under long-term use and under various external forces, it can effectively prevent the connection between the connecting plate 2 and the fixing block 4 from loosening, breaking and other problems, extend the service life of the device, ensure that the device can always work stably and reliably during the entire rehabilitation training process, and reduce the possibility of affecting the rehabilitation process due to damage to the device.

[0094] The finger hanging cover 7 is in a teardrop shape, and a gasket 71 is arranged inside the finger hanging cover 7 .

[0095] The finger hanging cover 7 is in the shape of a water drop, and this shape can closely fit the natural shape of the finger.

[0096] When the patient puts the injured finger into the sling, the teardrop-shaped design can evenly disperse the pressure on the finger and avoid excessive local pressure.

[0097] From a mechanical point of view, its smooth curve adapts to the contour of the fingers, and can follow the movement trajectory of the fingers during rehabilitation training movements such as flexion and extension of the fingers, without hindering the normal movement of the fingers, while providing stable support.

[0098] The gasket 71 arranged on the inner side plays a role in buffering and reducing friction.

[0099] The gasket 71 is usually made of a soft, skin-friendly and elastic material. During the patient's rehabilitation training, when the finger moves in the sling, the gasket 71 can buffer the friction between the finger and the sling, preventing secondary damage to the unhealed burned skin caused by friction.

[0100] For example, when the finger is bent or stretched, the gasket 71 can form a soft buffer layer between the finger and the inner wall of the holster to absorb the energy generated by friction and protect the fragile burned skin.

[0101] The teardrop-shaped design fits the fingers, reducing the pressure caused by the uncomfortable shape of the sling, making the patient more comfortable while wearing it.

[0102] Especially for patients who need to wear rehabilitation limiter devices for a long time for training, a comfortable wearing experience can improve their compliance in using the device and make them more willing to actively cooperate with rehabilitation training.

[0103] The cushioning effect of the gasket 71 further improves the comfort level, avoids the pain caused by friction, and allows the patient to perform rehabilitation training in a painless or slightly painful state, which helps to relieve the patient's anxiety caused by the pain.

[0104] The gasket 71 effectively reduces the friction on the burned skin and reduces the risk of skin damage.

[0105] In rehabilitation training, skin integrity is crucial for wound healing. Reducing friction can prevent new skin tissue from being worn away, promote faster and better wound healing, reduce the possibility of infection, create good conditions for finger rehabilitation, and help improve the effectiveness and safety of rehabilitation training.
