Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation exercisers, and in particular to a finger rehabilitation exerciser for rehabilitation nursing and a use method thereof. Background Art

[0002] The hands are the most frequently used part of all human organs. Due to frequent use, the hands are very susceptible to external injuries, such as fractures, tendon ruptures, and burns. Secondly, hand dysfunction is a common problem in hemiplegic patients. Therefore, whether it is external or internal factors, the condition that leads to hand movement disability will seriously affect the patient's daily living ability. During the treatment period, the joints of the palms and fingers lack activity for a long time. If sufficient rehabilitation training is not carried out after the disease is cured, the affected joints or muscles often become stiff, sticky, contracted, or edematous. Therefore, patients need to maintain long-term rehabilitation training.

[0003] At present, doctors will select an exerciser for patients based on the patient's condition, through the doctor's own experience and the patient's subjective judgment. This selection method has certain errors, because during the production process of the exerciser, in order to take into account the body shapes of as many patients as possible, the design itself has certain limitations and cannot accurately adapt to the contours of each patient's palm. As a result, after using it for a period of time, patients find that the exerciser is not strong enough or the exercise effect is not good.

[0004] In order to solve such problems, strength-adjustable exercisers have appeared on the market. However, most of the exercisers can only make overall adjustments to the strength during the adjustment process. Firstly, the flexion and extension abilities of each finger are different for each patient. During the strength adjustment process of the existing exercisers, it is impossible to take into account each finger according to the conditions of different patients. Secondly, the fingers cannot be well limited during the strength adjustment process of the exerciser, which results in the overall structure of the exerciser being unable to form a good match with the contour of the patient's fingers after the strength is adjusted. During use, the patient's finger surface is unevenly stressed and the finger position needs to be adjusted all the time, which brings inconvenience to the patient. Therefore, the present application provides a finger rehabilitation exerciser for rehabilitation nursing to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a finger rehabilitation exerciser for rehabilitation nursing. By setting an adjustment component, the adjustment component is divided into two groups and is respectively arranged on the outer surface of the thumb positioning plate and the outer surface of the rope dividing plate. The two groups of adjustment components can respectively adjust the strength of the patient's thumb and the other four fingers. Such a setting is to make the adjustment component more targeted in the process of adjusting the strength, so that the user can be more accurate and efficient in the process of adjusting the strength. By setting a buffer component, the buffer component is divided into five groups and is respectively arranged on five fingers. Such a setting allows the five fingers of the user to be subjected to pulling forces of different strengths during the flexion and extension process of the fingers, thereby improving the exercise effect. Combined with the limiting effect of the upper limit component on the user's fingers, the force on the surface of the user's fingers can be more uniform during the force adjustment process, and the exercise effect is better. The above setting can solve the technical problems that the existing exerciser cannot take into account each finger according to the situation of different patients during use, and the force on the finger surface of the patient is uneven during use, and the finger position needs to be adjusted all the time, which brings inconvenience to the patient.

[0014] Optionally, the buffer assembly includes a shield fixedly connected to the outer surface of the joint positioning plate and the outer surface of the thumb positioning plate, the inner surface of the shield is fixedly connected to a torsion spring, the outer surface of the shield is provided with a guide groove, the surface of the torsion spring is rotatably connected to a connecting sleeve, the surface of the connecting sleeve is fixedly connected to a connecting block, and the inner surface of the guide groove is slidably connected to an inclined plate.

[0015] Optionally, a deceleration slider is fixedly connected to the outer surface of the inclined plate, a deceleration groove is provided on the surface of the shield, and an elastic groove is provided on the surface of the inclined plate.

[0016] A method for using a finger rehabilitation exerciser for rehabilitation nursing, the method comprising:

[0017] Step 1: When using, the user puts on the glove and bends the fingers to make the second pulling rope move. During the movement of the second pulling rope, it not only drives the torsion spring to rotate and generate reverse pulling force, but also pulls the first pulling rope to deform and generate reverse pulling force. The pulling forces generated by the torsion spring and the first pulling rope act on the patient's fingers through the pulling block, so the user can achieve the effect of exercise by repeatedly flexing and extending the fingers;

[0018] Step 2: The user adjusts the length of the first pulling rope by rotating the adjusting sleeve. When the length of the first pulling rope is shortened, the pulling force on the second pulling rope will be increased, and when the length of the first pulling rope is extended, the pulling force on the second pulling rope will be reduced.

[0019] Step three, the user adjusts the distance between the guide groove and the torsion spring by sliding the inclined plate, thereby adjusting the reaction force generated during the rotation of the torsion spring. During the change of the reaction force, the pulling force of the torsion spring on the second pulling rope also changes accordingly. The user adjusts the position of the inclined plate on different fingers to achieve the effect of adjusting the size of the reaction force of the torsion spring on different fingers.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, by setting the limit component, the wrist, back of the hand and fingers can be fully limited and protected according to the hand contours of different users, thereby improving the stability of the coordination between the patient's fingers and gloves during the flexion and extension of the fingers, thereby allowing the patient to have higher safety and better comfort during flexion and extension exercises.

[0022] By setting up the adjustment component, not only can the length of the first pulling rope be adjusted, but the adjustment sleeve is a one-way limited rotating structure. Such a setting allows the user to be more efficient and convenient during the adjustment process. In addition, the adjustment component is divided into two groups and is respectively arranged on the outer surface of the thumb positioning plate and the outer surface of the rope dividing plate. These two groups of adjustment components can respectively adjust the strength of the patient's thumb and the other four fingers. Such a setting is to make the adjustment component more targeted in the process of adjusting the strength, thereby allowing the user to be more accurate and efficient in the process of adjusting the strength.

[0023] By setting up a buffer component, the buffer component is divided into five groups and is respectively set on five fingers. Since the tension of the torsion spring can be adjusted by the inclined plate, the tension on the five fingers can be adjusted individually. Such a setting allows the five fingers of the user to be subjected to tension of different strengths during the flexion and extension process, thereby improving the exercise effect. Moreover, the connecting block on the surface of the buffer component is the connection point between the second pull rope and the first pull rope. Such a setting allows the connecting block to serve as the force fulcrum of the second pull rope. Since the adjusting sleeve is fixed on the outer surface of the glove, the force point of each finger will not change during the force adjustment process. Combined with the limiting effect of the upper limit component on the user's fingers, the force on the surface of the user's fingers can be more evenly applied during the force adjustment process, and the exercise effect can be better.

[0045] like Figures 1 to 12 As shown, an embodiment of the present invention provides a finger rehabilitation exerciser for rehabilitation nursing, including a glove 1, a wrist cuff 2 is provided on the outer surface of the glove 1, a limiting component is provided on the surface of the glove 1, the limiting component is used to limit the patient's fingers, the limiting component is respectively connected to the glove 1 and the wrist cuff 2, an adjusting component is provided on the outer surface of the glove 1, the adjusting component is used to adjust the tension of the glove 1, the adjusting component is connected to the limiting component, a buffer component is provided on the outer surface of the glove 1, the buffer component is used to adjust and buffer the pulling force generated by the glove 1 on the patient's fingers, and the buffer component is connected to the limiting component.

[0046] As an implementation method in this embodiment, Figures 1 to 6As shown, the limiting assembly includes a back-of-hand positioning piece 3 fixedly connected to the outer surface of the wrist cuff 2, a rope dividing plate 4 fixedly connected to the upper surface of the back-of-hand positioning piece 3, a thumb positioning piece 5 fixedly connected to the outer surface of the wrist cuff 2, a wrist clip 12 fixedly connected to the inner surface of the glove 1, a joint positioning piece 7 fixedly connected to the outer surface of the glove 1, a finger sleeve 8 is provided on the surface of the joint positioning piece 7, a pull block 35 is fixedly connected to the outer surfaces of the finger sleeve 8 and the thumb positioning piece 5, a second pulling rope 36 is fixedly connected to the surface of the pull block 35, the adjusting assembly is respectively connected to the rope dividing plate 4 and the thumb positioning piece 5, the buffer assembly is respectively connected to the joint positioning piece 7 and the thumb positioning piece 5, the back-of-hand positioning piece The two ends of 3 are respectively fixed on the outer surface of the wrist cuff 2 and the outer surface of the back of the hand plate 6. Such a setting can not only position the back of the patient's hand, but also improve the stability of the connection between the back of the hand and the wrist of the patient. The thumb positioning piece 5 is distributed on the outer surface of the thumb in a Y shape. The Y-shaped structure is set to adapt to the structural contour between the thumb and the flexor pollicis brevis, thereby limiting the thumb and improving the stability of the thumb during bending. The joint positioning piece 7 is set on the outer surface of the four finger joints, and is covered on the outer surface of the finger joint in an arc-shaped structure. Such a setting is on the one hand to limit the finger joints of the user, and on the other hand to protect the finger joints, thereby improving the safety of the finger joints.

[0047] In this embodiment, if Figures 3 to 6 As shown, the lower surface of the back of hand positioning piece 3 is fixedly connected with the back of hand plate 6, the lower surface of the thumb positioning piece 5 is fixedly connected with the flexor pollicis brevis positioning piece 11, and the surface of the wrist clamping piece 12 is fixedly connected with the clamping block 13. The curved surface contour formed by the multiple groups of wrist clamping pieces 12 is consistent with the contour of the inner surface of the wrist sleeve 2. The setting of the clamping block 13 can increase the adaptability and fit between the wrist clamping piece 12 and the user's wrist, thereby improving the stability of the glove 1 during use, and preventing the glove 1 from being dislocated and detached. The surface of the finger sleeve 8 is provided with a joint avoidance groove 10, and the surface of the finger sleeve 8 is fixedly connected with the finger The contours of the joint clip 9 and the finger sleeve 8 match the contours of human fingers. This arrangement can improve the comfort of the user's fingers on the one hand, and on the other hand, the finger sleeve 8 can be used to limit the finger. The finger joint clip 9 is arranged on the surface of the finger sleeve 8. This arrangement can use the finger joint clip 9 to apply an inward clamping force to the patient's fingers, thereby making the finger sleeve 8 suitable for more patients. The joint avoidance groove 10 is opened on the outer surface of the finger sleeve 8. This arrangement is to reduce the resistance encountered by the user during the bending of the finger, thereby improving the comfort and safety of the patient during the flexion and extension of the finger.

[0048] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figures 7 to 9As shown, the adjustment component includes a base 14 fixedly connected to the outer surface of the rope dividing plate 4 and the outer surface of the thumb positioning plate 5, the upper surface of the base 14 is fixedly connected to the toothed outer plate 15, the inner surface of the toothed outer plate 15 is rotatably connected to the adjustment sleeve 16, the surface of the adjustment sleeve 16 is fixedly connected to a convex elastic sheet 17, the outer surface of the convex elastic sheet 17 is fixedly connected to the toothed inner plate 18, the lower surface of the adjustment sleeve 16 is fixedly connected to a limited bottom plate 20, the inner surface of the adjustment sleeve 16 is fixedly connected to a winding rod 22, the outer surface of the winding rod 22 is provided with a first pulling rope 23, the first pulling rope 23 has elastic properties, and the user rotates the adjustment sleeve During the adjustment process of adjusting sleeve 16, the toothed inner plate 18 and the toothed outer plate 15 are matched with each other through the teeth. The shapes of the teeth on the surfaces of the toothed inner plate 18 and the toothed outer plate 15 have two special surfaces, one is an inclined surface, and the other is a flat straight surface. During the rotation of the adjusting sleeve 16, the toothed inner plate 18 will rotate along the inclined surface, and cannot be reversed under the limiting action of the straight surface. During the rotation of the toothed inner plate 18, the reset spring piece 19 will be driven to deform and contract. The setting of the reset spring piece 19 can make the toothed inner plate 18 and the toothed outer plate 15 always limited by the teeth, thereby realizing the limiting effect of the unidirectional rotation of the adjusting sleeve 16.

[0049] In this embodiment, if Figure 1 , Figure 2 and Figures 7 to 9 As shown, the upper surface of the base 14 is provided with a scale, and the upper surface of the adjusting sleeve 16 is provided with a pointer. The scale and the pointer are provided to provide a reference for the user, so that the user can be more precise in the adjustment process. The lower surface of the winding rod 22 is fixedly connected to the limiting sleeve 25, and the upper surface of the base 14 is fixedly connected to the limiting block 24. The outer surface of the convex spring piece 17 is fixedly connected to the reset spring piece 19, and the toothed inner plate 18 and the convex spring piece 17 are fixedly connected by the reset spring piece 19. The outer surface of the adjusting sleeve 16 is provided with a weakening groove 21. The setting of the convex spring piece 17 allows the adjusting sleeve 16 to have an elastic force that expands outward. On the one hand, such a setting can cooperate with the reset spring piece 19 to improve the toothed inner plate 1 8 and the toothed outer plate 15 have a stable fit, and on the other hand, can form a fit with the weakened groove 21. The user presses the weakened groove 21 to make the convex spring piece 17 deform and shrink inward. During the inward contraction of the convex spring piece 17, the toothed inner plate 18 and the toothed outer plate 15 will be out of limit. When the two are released from limit, the user can reversely rotate the adjusting sleeve 16. When the adjusting sleeve 16 rotates, the winding rod 22 on its inner surface will wind and release the first traction rope 23, thereby changing the pulling force of the first traction rope 23 on the second traction rope 36. The setting of the limit block 24 and the limit sleeve 25 can not only limit the winding rod 22, but also improve the stability of the winding rod 22 during rotation.

[0050] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figures 10 to 12 As shown, the buffer assembly includes a shield 26 fixedly connected to the outer surface of the joint positioning plate 7 and the outer surface of the thumb positioning plate 5, the inner surface of the shield 26 is fixedly connected to a torsion spring 27, the outer surface of the shield 26 is provided with a guide groove 28, the surface of the torsion spring 27 is rotatably connected to a connecting sleeve 29, the surface of the connecting sleeve 29 is fixedly connected to a connecting block 30, the inner surface of the guide groove 28 is slidably connected to an inclined plate 31, and the surface of the inclined plate 31 is provided with an elastic groove 34. When the user bends the finger, the second pulling rope 36 will first drive the torsion spring 27 to rotate. During the rotation of the torsion spring 27, not only will the first pulling rope 23 be pulled to deform, but the second pulling rope 36 will also be deformed by the elastic force. In order to generate reverse pulling force and allow the user to adjust the pulling force of the torsion spring 27, an inclined plate 31 is provided on the surface of the guide groove 28. When the torsion spring 27 slides over the surface of the inclined plate 31, pressure is generated on the inclined plate 31. The friction between the inclined plate 31 and the torsion spring 27 is increased under the action of pressure, thereby increasing the pulling force of the torsion spring 27 on the second pulling rope 36. When the torsion spring 27 is reset and slides out of the inclined plate 31, the inclined plate 31 is deformed again under the action of the elastic groove 34 so as to cooperate with the torsion spring 27 again. Since the inclined plate 31 can slide on the outer surface of the guide groove 28, the user can adjust the reverse pulling force of the torsion spring 27 on the second pulling rope 36 by adjusting the position of the inclined plate 31.

[0051] In this embodiment, if Figures 10 to 12 As shown, the outer surface of the inclined plate 31 is fixedly connected with a deceleration slider 32, and the surface of the shield 26 is provided with a deceleration groove 33. The inclined plate 31 and the shield 26 are connected by the deceleration groove 33 and the deceleration slider 32. The setting of the deceleration groove 33 and the deceleration slider 32 can fix the position of the inclined plate 31 by means of friction, so that after the inclined plate 31 is slid to the specified position, it can be fixed on the surface of the guide groove 28 without the help of external force.

[0052] The present application also provides a method for using a finger rehabilitation exerciser for rehabilitation nursing, comprising the following steps:

[0053] Step 1: When using, the user puts the glove 1 on the hand and moves the second pulling rope 36 by bending the fingers. During the movement, the second pulling rope 36 will not only drive the torsion spring 27 to rotate and generate reverse tension, but also pull the first pulling rope 23 to deform and generate reverse tension. The tension generated by the torsion spring 27 and the first pulling rope 23 acts on the patient's fingers through the pulling block 35, so the user can achieve the effect of exercise by repeatedly flexing and extending the fingers.

[0054] Step 2: The user adjusts the length of the first pulling rope 23 by rotating the adjusting sleeve 16. The length of the first pulling rope 23 will increase the pulling force on the second pulling rope 36 during the shortening process, and the length of the first pulling rope 23 will reduce the pulling force on the second pulling rope 36 during the lengthening process.

[0055] Step three, the user adjusts the distance between the guide groove 28 and the torsion spring 27 by sliding the inclined plate 31, thereby adjusting the reaction force generated by the torsion spring 27 during the rotation process. During the change of the reaction force, the pulling force of the torsion spring 27 on the second pulling rope 36 also changes accordingly. The user adjusts the position of the inclined plate 31 on different fingers to achieve the effect of adjusting the size of the reaction force of the torsion spring 27 on different fingers.

[0056] The technical solution provided by the present invention is to set a limit component, and the two ends of the wrist cuff are fixed to the outer surface of the glove by Velcro. The Velcro is selected to adapt to users with different wrist thicknesses. The wrist clip is arranged on the inner surface of the glove, and the curved surface contour composed of multiple groups of wrist clips is consistent with the contour of the inner surface of the wrist cuff. In addition, a clamping block is also arranged on the inner surface of the wrist clip. The arrangement of the clamping block can increase the adaptability and fit between the wrist clip and the user's wrist. The above arrangement can improve the stability of the gloves during use and prevent the gloves from being dislocated and detached.

[0057] By providing a back-of-hand positioning piece, a thumb positioning piece and a joint positioning piece, the two ends of the back-of-hand positioning piece are respectively fixed on the outer surface of the wrist cuff and the outer surface of the back-of-hand plate. Such a setting can not only position the back of the patient's hand, but also improve the stability of the connection between the back of the hand and the wrist of the patient. The thumb positioning piece is distributed in a Y shape on the outer surface of the thumb. The Y-shaped structure is set to adapt to the structural contour between the thumb and the flexor pollicis brevis, thereby limiting the thumb and improving the stability of the thumb during bending. The joint positioning pieces are set on the outer surfaces of the four finger joints, and are covered on the outer surfaces of the finger joints in an arc-shaped structure. Such a setting is on the one hand to limit the user's finger joints, and on the other hand to protect the finger joints, thereby improving the safety of the finger joints.

[0058] By arranging finger sleeves, knuckle clips and joint avoidance grooves, the finger sleeves are arranged on the outer surface of the gloves, and the contour of the finger sleeves matches the contour of human fingers. Such an arrangement can improve the comfort of the user's fingers on the one hand, and on the other hand, the fingers can be limited with the help of the finger sleeves. The knuckle clips are arranged on the surface of the finger sleeves. Such an arrangement can apply an inward clamping force to the patient's fingers with the help of the knuckle clips, thereby making the finger sleeves suitable for more patients. The joint avoidance grooves are opened on the outer surface of the finger sleeves. Such an arrangement is to reduce the resistance of the user's fingers during bending, thereby improving the comfort and safety of the patient in the process of flexing and extending the fingers.

[0059] Through the above description, the limit component can limit and protect the wrist, back of the hand and fingers in an all-round way according to the hand contours of different users, thereby improving the stability of the coordination between the fingers and the gloves during the flexion and extension of the fingers of the patients, thereby allowing the patients to have higher safety and better comfort during flexion and extension exercises.

[0060] By setting an adjustment component, when the user rotates the adjustment sleeve, the toothed inner plate and the toothed outer plate are matched with each other through the teeth. The shape of the teeth on the surfaces of the toothed inner plate and the toothed outer plate has two special surfaces, one is an inclined surface, and the other is a flat straight surface. During the rotation of the adjustment sleeve, the toothed inner plate will rotate along the inclined surface, and cannot be reversed under the limiting action of the straight surface. During the rotation of the toothed inner plate, the reset spring plate will be driven to deform and contract. The setting of the reset spring plate can allow the toothed inner plate and the toothed outer plate to be limited by the teeth at all times, thereby achieving a limiting effect on the unidirectional rotation of the adjustment sleeve.

[0061] By setting a convex spring piece and a weakened groove, the setting of the convex spring piece allows the adjusting sleeve to have an elastic force to expand outward. Such a setting can cooperate with the reset spring piece on the one hand to improve the stability of the cooperation between the toothed inner plate and the toothed outer plate, and on the other hand, it can cooperate with the weakened groove. The user presses the weakened groove to deform the convex spring piece and shrink inward. During the inward contraction of the convex spring piece, the toothed inner plate and the toothed outer plate will be released from the limit. When the two are released from the limit, the user can rotate the adjusting sleeve in the opposite direction. When the adjusting sleeve rotates, the winding rod on its inner surface will wind and release the first pulling rope, thereby changing the pulling force of the first pulling rope on the second pulling rope. The setting of the limit block and the limit sleeve can not only limit the winding rod, but also improve the stability of the winding rod during rotation.

[0062] Through the above description, the adjustment component can not only adjust the length of the first pulling rope, but also the adjustment sleeve is a one-way limited rotating structure. Such a setting allows the user to be more efficient and convenient during the adjustment process.

[0063] By setting up a buffer component, when the user bends his fingers, the second pulling rope will first drive the torsion spring to rotate. During the rotation of the torsion spring, not only will the first pulling rope be deformed, but the torsion spring itself will also generate a reverse pulling force on the second pulling rope under the action of elastic force. In order to allow the user to adjust the pulling force of the torsion spring, an inclined plate is set on the surface of the guide groove. When the torsion spring slides over the surface of the inclined plate, pressure is generated on the inclined plate. The friction between the inclined plate and the torsion spring will increase under the action of pressure, thereby increasing the pulling force of the torsion spring on the second pulling rope. When the torsion spring resets and slides out of the inclined plate, the inclined plate will restore its deformation under the action of the elastic groove so as to cooperate with the torsion spring again. Since the inclined plate can slide on the outer surface of the guide groove, the user can adjust the reverse pulling force of the torsion spring on the second pulling rope by adjusting the position of the inclined plate.

[0064] By setting a deceleration slider and a deceleration groove, the inclined plate and the guard cover are connected through the deceleration groove and the deceleration slider. The setting of the deceleration groove and the deceleration slider can fix the position of the inclined plate with the help of friction, so that after the inclined plate is slid to the specified position, it can be fixed on the surface of the guide groove without the help of external force. The surface of the guide groove is also chamfered, and the chamfer setting can facilitate the user to slide the inclined plate.

[0065] It is worth mentioning that the buffer component is divided into five groups and is respectively arranged on five fingers. Since the tension of the torsion spring can be adjusted through the inclined plate, the tension on the five fingers can be adjusted individually. Such a setting allows the user's five fingers to be subjected to tension of different intensities during the flexion and extension process, thereby improving the exercise effect. Moreover, the connecting block on the surface of the buffer component is the connection point between the second pull rope and the first pull rope. Such a setting allows the connecting block to serve as the force fulcrum of the second pull rope. Since the adjusting sleeve is fixed on the outer surface of the glove, the force point of each finger will not change during the force adjustment process. Combined with the limiting effect of the upper limit component on the user's fingers, the force on the surface of the user's fingers can be more evenly distributed during the force adjustment process, and the exercise effect is better.

[0066] Furthermore, the adjustment components are divided into two groups and are respectively arranged on the outer surface of the thumb positioning plate and the outer surface of the rope dividing plate. These two groups of adjustment components can respectively adjust the strength of the patient's thumb and the other four fingers. The starting point of this setting is that the bending direction and flexion and extension ability of the human thumb are different from those of the four fingers. The separate adjustment setting is to make the adjustment component more targeted in the process of adjusting the strength, so that the user can be more precise and efficient in the process of adjusting the strength.
