Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation gloves, in particular to a pair of soft rehabilitation gloves. Background Art

[0002] With the increasing incidence of cardiovascular and cerebrovascular diseases, most patients with stroke, cerebral palsy or other forms of brain injury will have varying degrees of hand function impairment and generally require long-term physical rehabilitation therapy, which mainly includes some of the same simple repetitive movements, such as repeated extension and bending of fingers, constant frequency twisting or lifting of the wrist, etc., in order to help reshape the brain's motor nerves, improve the motor function of the wrist and fingers, and restore the hand's basic grasping ability and daily activity ability.

[0003] In view of the current shortage of medical resources, it is too expensive for medical staff to perform simple, highly repetitive, and inefficient manual assisted physical therapy on the patient's hand one-on-one, which is relatively time-consuming. In order to replace manual assistance in hand rehabilitation exercises for patients and solve the current shortage of professional medical labor resources, research on hand finger joint rehabilitation technology is emerging. Based on rehabilitation medicine theory, finger passive joint range of motion training and finger active flexion and extension resistance training can enhance the proprioception of the affected limb, enhance limb reflexes, promote active movement, prevent muscle atrophy, and improve joint mobility through repeated exercise training of the affected limb. On the other hand, it greatly promotes the reorganization and compensation of the nervous system, and assists the gradual recovery of the lost functions of the affected limb. Many different types of hand rehabilitation training equipment have appeared on the market to provide long-term physical therapy for patients.

[0004] In terms of rehabilitation medicine theory, pneumatically controlled rehabilitation training gloves mainly perform passive joint range of motion training and active finger flexion and extension resistance training on the patient's hand. On the one hand, they enhance the proprioception of the affected limb, enhance limb reflexes, promote active movement, prevent muscle atrophy, and improve joint range of motion; on the other hand, they greatly promote the reorganization and compensation of the nervous system, and assist the affected limb in gradually recovering the lost functions.

[0005] However, the existing processing equipment has the following shortcomings:

[0006] When the existing rehabilitation gloves are in use, such as CN113133902A, they need to cooperate with each other to provide various data of hand movements. When the hand wearing the rehabilitation gloves grasps or simply bends the fingers, it is necessary to sense the bending degree and force of the fingers through a flexible pressure sensor, and at the same time, it is necessary to collect the hand posture through a six-axis gyroscope, and then the temperature sensor is needed to collect information such as hand temperature; the main controller sends the hand information to the computer virtual interface through the Bluetooth transmission module to display various parameters. The patient's autonomous recovery steps are relatively cumbersome and cannot substantially change the patient's strength recovery. Improvements are needed.

[0007] Therefore, we propose a soft rehabilitation glove to solve the above problems. Summary of the invention

[0008] The object of the present invention is to provide a soft rehabilitation glove, in which elastic actuator knuckles are arranged at the positions of the five fingers. After the air source connected air tube is filled with controllable air pressure, the front and rear colloidal air tube knuckle parts of the elastic actuator knuckles will expand or contract, thereby realizing a directional bending, ensuring the basic bending deformation effect of the glove body, and at the same time, the first elastic actuator bellows structure in the middle section will produce directional elongation or compression, and the elastic modulus weak side bellows and the elastic modulus strong side bellows will produce a certain bending while stretching and compressing. When the positive pressure realizes the bending of the hand, the elongation of the middle section enables the glove body to have a good adaptability to the bending of the proximal knuckles of the fingers (when the knuckles are bent, the skin wrinkles of the fingers are elongated), so as to solve the problems raised by the above-mentioned background technology.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a soft rehabilitation glove, comprising a glove body, an elastic actuator knuckle, a first elastic actuator bellows, and an air source connecting air pipe, wherein the elastic actuator knuckle is arranged on the inner wall of the glove body, the first elastic actuator bellows is assembled with the surface of the elastic actuator knuckle, and the air source connecting air pipe is inserted and connected with the inner wall of the first elastic actuator bellows. By setting the air source connecting air pipe, the elastic actuator knuckle can collide or contract after being filled with controllable air pressure, thereby realizing bending in a directional dimension.

[0010] Preferably, the surface of the elastic actuator knuckle is equipped with a colloid air tube, and the colloid air tube is assembled with the surface of the air source connecting air tube. By setting the connection between the colloid air tube and the air source connecting air tube, it is convenient to stably introduce the air pressure into the first elastic actuator bellows.

[0011] Preferably, the surface of the first elastic actuator bellows is sleeved with a thickened outer ring, and both ends of the first elastic actuator bellows are equipped with thickened blocks, and the thickened blocks are sleeved with the connecting ends of the elastic actuator knuckles. By providing the thickened outer ring, the rigidity and action force of the first elastic actuator bellows can be easily improved.

[0012] Preferably, the surface of the first elastic actuator bellows is equipped with an adhesive block, and the adhesive block is adhered to the inner wall of the glove body. By providing the adhesive block, the bonding strength between the first elastic actuator bellows and the glove body can be improved.

[0013] Preferably, the inner wall of the first elastic actuator bellows is provided with a weak-side bellows with an elastic modulus, and the inner wall of the first elastic actuator bellows is provided with a bellows airway opening, and the bellows airway opening is connected to an air source connecting air pipe through and through, and by setting the coordination between the bellows airway opening and the air source connecting air pipe, it is convenient to deliver air pressure to the inside of the first elastic actuator bellows.

[0014] Preferably, the inner wall of the knuckle of the elastic actuator is provided with an internal airway opening of the knuckle segment, and the internal airway opening of the knuckle segment is connected to an air source connecting air pipe through it. By setting the coordination between the internal airway opening of the knuckle segment and the air source connecting air pipe, it is convenient to deliver air pressure to the knuckle of the elastic actuator.

[0015] Preferably, a side bellows with a strong elastic modulus is provided on the first elastic actuator bellows away from the side bellows with a weak elastic modulus. By providing the side bellows with a strong elastic modulus, the toughness of the first elastic actuator bellows can be easily improved.

[0016] Preferably, the surface of the knuckle of the elastic actuator is varicose to present a bent knuckle segment, and the bent knuckle segment is in a contracted shape. By bending the knuckle segment, the knuckle of the elastic actuator is in a specific arc when bent, and the user can maintain a stable bending angle, making the recovery more regular.

[0017] Preferably, the first elastic actuator bellows has a bellows-segment curved shape on one side close to the bending finger segment. By setting the bellows-segment curved shape, the first elastic actuator bellows is conveniently bent at a specific arc, and the user can maintain a stable bending angle.

[0018] Preferably, the surface of the elastic actuator knuckle is varicose and presents a reverse bent knuckle shape, and the side of the first elastic actuator bellows close to the reverse bent knuckle shape is in a reverse bent shape of the corrugated segment. By setting the bent knuckle shape and the reverse bent shape of the corrugated segment, the elastic actuator knuckle and the first elastic actuator bellows can maintain a stable curvature in the contracted state when driven by negative pressure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention arranges rehabilitation gloves, and elastic actuator knuckles are arranged at the positions of the five fingers. After the air source connecting air tube is filled with controllable air pressure, the front and rear colloidal air tube knuckle parts of the elastic actuator knuckles will expand or contract, thereby realizing a directional bending, ensuring the basic bending deformation effect of the glove body, and at the same time, the first elastic actuator bellows structure in the middle section will produce directional elongation or compression, and the bellows on the weak side of the elastic modulus and the bellows on the strong side of the elastic modulus will produce a certain bending while elongating and compressing. When the positive pressure realizes the bending of the hand, the elongation of the middle section makes the glove body have a good adaptation effect to the bending of the proximal knuckles of the fingers (when the knuckles are bent, the skin wrinkles of the fingers are elongated), greatly improving the bending effect while reducing the degree of compression of the proximal knuckles, and can also improve the wearing comfort during the action. When the negative pressure realizes the relaxation of the hand, the compression of the middle section will cause the glove body to produce an inward traction force on the fingertips, which not only improves the relaxation effect, but also enhances the resistance capacity of the glove body, so that it can better complete the patient's hand resistance training. By setting the elastic cloth, the bending function can be realized. At the same time, the mid-end first elastic actuator bellows structure improves the bending effect and can achieve large-scale bending, which is far superior to the medical gloves on the existing market. The resistance is improved, so that the gloves can produce greater resistance. During negative pressure stretching, the patient's hands can undergo better confrontation training. High-performance stretching and bending exist at the same time, which is a high-efficiency dual function that ordinary gloves cannot achieve. It reduces the pressure on the proximal interphalangeal joints, improves comfort, and makes the movement effect softer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] 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 implementation regulations described 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.

[0030] Embodiment 1:

[0031] See also Figure 1-7 As shown, the present invention provides a technical solution: a soft rehabilitation glove, comprising a glove body 3, an elastic actuator knuckle 1, a first elastic actuator bellows 2, and an air source connecting air pipe 4, wherein the elastic actuator knuckle 1 is arranged on the inner wall of the glove body 3;

[0032] according to Figure 1 As shown, the first elastic actuator bellows 2 is assembled with the surface of the elastic actuator knuckle 1, and the air source connecting air pipe 4 is inserted and connected with the inner wall of the first elastic actuator bellows 2. By setting the air source connecting air pipe 4, the elastic actuator knuckle 1 can collide or contract after being filled with controllable air pressure, thereby realizing bending in a directional dimension.

[0033] according to Figure 2 As shown, the surface of the elastic actuator knuckle 1 is equipped with a colloid air tube 5, and the colloid air tube 5 is surface-assembled with the air source connecting air tube 4. By setting the connection between the colloid air tube 5 and the air source connecting air tube 4, it is convenient to stably introduce the air pressure into the first elastic actuator bellows 2.

[0034] according to Figure 3As shown, a thickened outer ring 6 is sleeved on the surface of the first elastic actuator bellows 2, and thickened blocks 7 are installed at both ends of the first elastic actuator bellows 2. The thickened blocks 7 are sleeved and connected to the connecting ends of the elastic actuator knuckles 1. By providing the thickened outer ring 6, the rigidity and action force of the first elastic actuator bellows 2 can be easily improved.

[0035] according to Figure 3 As shown, the surface of the first elastic actuator bellows 2 is equipped with an adhesive block 8, and the adhesive block 8 is adhered to the inner wall of the glove body 3. By providing the adhesive block 8, the bonding strength between the first elastic actuator bellows 2 and the glove body 3 is easily improved.

[0036] according to Figure 4 As shown, the inner wall of the first elastic actuator bellows 2 is provided with a weak-side bellows 9 with an elastic modulus, and the inner wall of the first elastic actuator bellows 2 is provided with a bellows airway opening 10, and the bellows airway opening 10 is connected to the air source connecting air pipe 4 through the bellows airway opening 10. By setting the coordination between the bellows airway opening 10 and the air source connecting air pipe 4, it is convenient to deliver the air pressure to the inside of the first elastic actuator bellows 2.

[0037] according to Figure 4 As shown, the inner wall of the elastic actuator knuckle 1 is provided with an internal airway opening 11 of the knuckle segment, and the internal airway opening 11 of the knuckle segment is connected to the air source connecting air pipe 4 through it. By setting the coordination between the internal airway opening 11 of the knuckle segment and the air source connecting air pipe 4, it is convenient to deliver air pressure to the elastic actuator knuckle 1.

[0038] according to Figure 4 As shown, a side of the first elastic actuator bellows 2 away from the weak elastic modulus side bellows 9 is provided with a strong elastic modulus side bellows 12. By providing the strong elastic modulus side bellows 12, the toughness of the first elastic actuator bellows 2 can be easily increased.

[0039] according to Figure 5 As shown, the surface of the elastic actuator knuckle 1 is varicose to present a bent knuckle segment 13, and the bent knuckle segment 13 is in a contracted state. By bending the knuckle segment 13, the elastic actuator knuckle 1 is in a specific arc when bent, and the user can maintain a stable bending angle to make the recovery more regular.

[0040] according to Figure 5 As shown, the first elastic actuator bellows 2 has a bellows bend 14 on one side close to the bending finger segment 13. By setting the bellows bend 14, the first elastic actuator bellows 2 is conveniently bent at a specific arc, and the user can maintain a stable bending angle.

[0041] according to Figure 5As shown, the surface of the elastic actuator knuckle 1 is varicose and presents a reverse bent knuckle shape 15, and the side of the first elastic actuator bellows 2 close to the reverse bent knuckle shape 15 is in a corrugated segment reverse bent shape 16. By setting the bent knuckle shape and the corrugated segment reverse bent shape 16, the elastic actuator knuckle 1 and the first elastic actuator bellows 2 can maintain a stable curvature in the contracted state when driven by negative pressure.

[0042] Embodiment 2: It also includes a large-size limit block 17, which is arranged inside the glove body 3. A second elastic actuator bellows 20 is installed at one end of the large-size limit block 17. A connecting boss 19 is installed on the surface of the second elastic actuator bellows 20. One end of the connecting boss 19 is fixedly connected to the inside of the glove body 3. A small-size limit block 18 is installed at one end of the second elastic actuator bellows 20. The large-size limit block 17 provides basic stiffness for the entire actuator to move, and is also the starting point of the force for the actuator to move. The small-size limit block 18 is used to connect the second elastic actuator bellows 20 at both ends and provide basic stiffness. The connecting boss 19 is used to connect to the glove body 3, so that the traction brought by the deformation process of the second elastic actuator bellows 20 can better act on the glove body 3, thereby enhancing the expansion and contraction effects of the glove body 3.

[0043] The effect achieved by the entire mechanism is as follows: by setting up the rehabilitation gloves, the five fingers are provided with elastic actuator knuckles 1, and after the air source connecting air tube 4 is filled with controllable air pressure, the front and rear colloid air tube 5 knuckle parts of the elastic actuator knuckle 1 will expand or contract, thereby achieving a directional bending, ensuring the basic bending deformation effect of the glove body 3, and at the same time, the first elastic actuator bellows 2 structure in the middle section will produce directional elongation or compression, and the elastic modulus weak side bellows 9 and the elastic modulus strong side bellows 12 will produce a certain bending while elongating and compressing. When the hand is bent by positive pressure, the elongation of the middle section makes the glove body 3 have a good adaptation effect on the bending of the proximal interphalangeal joint of the finger. When the finger joint is bent, the wrinkles of the finger skin are elongated, which greatly improves the bending effect while reducing the pressure on the proximal interphalangeal joint, and can also improve the wearing comfort during the action. When the hand is relaxed by negative pressure, the compression of the middle section will cause the glove body 3 to produce an inward traction force on the fingertips. This force not only improves the relaxation effect, but also enhances the resistance capacity of the glove body 3, so that it can better complete the patient's hand resistance training. By setting the elastic cloth, the bending function can be achieved. The structure of the first elastic actuator bellows 2 at the middle end improves the bending effect and can achieve a large bending, which is far superior to the medical gloves on the existing market. The resistance capacity is improved, so that the gloves can generate greater resistance. When the negative pressure is stretched, the patient's hand can be better trained. High-performance stretching and bending exist at the same time, which is a high-efficiency dual function that ordinary gloves cannot achieve. It reduces the pressure on the proximal interphalangeal joint and improves comfort, and the action effect is softer.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
