Description

Technical Field

[0001] The present invention relates to the technical field of neurology nursing, and more specifically, to a lower limb health rehabilitation device and a rehabilitation method for neurology nursing. Background Art

[0002] Lower limb conditions involved in neurology mainly stem from central or peripheral nervous system injuries. The following is a detailed classification and analysis of clinical characteristics: I. Lower limb dysfunction caused by central nervous system injury 1. Lower limb paralysis after stroke: Pathological mechanism: Injury to the cerebral motor cortex or pyramidal tract causes a mixed paralysis of upper / lower motor neurons; Typical manifestation is the synergistic movement pattern above stage III of the Brunnstrom staging; Clinical manifestations: Spastic paralysis (high muscle tone): clasp-knife rigidity, circumduction gait; Flaccid paralysis (low muscle tone): foot drop, genu recurvatum; Proprioceptive disorder: Absence of joint position sense leads to unsteady gait.

[0003] 2. Movement disorders related to Parkinson's disease: Specific manifestations: Freezing of gait (FOG): hesitant start, short steps with dragging; Flexed posture: Anterior trunk inclination causes the center of gravity to shift forward, making it easy to fall; Bradykinesia: Decreased step frequency (<100 steps / minute).

[0004] II. Core treatment for high muscle tone 1. Physiological mechanism and neuroinhibitory effect of stretching training: By static stretching (for more than 30 seconds), the Golgi tendon organ (GTO) is activated, inhibiting the activity of α motor neurons and reducing the reflexive contraction of muscles; when passively stretching the hamstring muscles, the end-terminal angle needs to be maintained to trigger the stress relaxation effect.

[0005] 2. Biomechanical remodeling: Long-term stretching can change the viscoelasticity of muscles, reduce collagen fiber cross-linking, and increase joint range of motion.

[0006] 3. Clinical application method: Passive stretching: such as prone knee flexion stretching (to increase knee flexion range of motion) or supine straight leg raising to stretch the hamstring muscles, which needs to be combined with breathing control (deepening the angle during exhalation).

[0007] 4. Instrument-assisted: Robot stretching equipment can precisely control the stretching angle and speed, reducing the physical consumption of therapists.

[0008] 5. Combined therapy: Hot compress (40 - 45 °C) combined with stretching can enhance muscle extensibility; cold compress (10 - 15 °C) is used for acute spasm relief.

[0009] III. Rehabilitation Strategies for Low Muscle Tone 1. Scientific Basis of Load Movement: Gravity Adaptation Training: Activate type II fast-twitch muscle fibers through resistance exercise (such as 60%-80% 1RM load) to stimulate motor unit recruitment. For example, closed-chain training (wall-sit) can enhance the proximal stability of the lower limbs.

[0010] 2. Vestibular-Proprioceptive Integration: Balance training (single-leg standing on a foam pad) and vibration platform (30-50 Hz) can strengthen the gravity perception system and improve postural control.

[0011] Currently, for the treatment of high or low muscle tone in lower limb rehabilitation, muscle stretching and resistance exercise are mostly used. For the problem of muscle tone, artificial assisted treatment is mostly used, with cumbersome treatment means and long treatment time, and it is time-consuming and laborious for nursing staff to operate. In view of this, we propose a lower limb health rehabilitation device and its rehabilitation method for neurological nursing. Summary of the Invention

[0012] The purpose of the present invention is to provide a lower limb health rehabilitation device for neurological nursing, so as to solve the technical problem that the existing artificial nursing treatment for muscle tone problems is time-consuming and laborious.

[0013] To solve the above technical problems, the present invention provides the following technical solution: A lower limb health rehabilitation device for neurology nursing, comprising a waist restraint main body; on both sides of the bottom of the waist restraint main body, drive rehabilitation units are symmetrically arranged; on the drive rehabilitation units, mimic femur components are arranged; at the lower end of the mimic femur components, a drive type lower limb control unit is arranged; below the drive type lower limb control unit, mimic tibia components are arranged; below the mimic tibia components, foot restraint components are arranged; the drive type lower limb control unit has two output ends, wherein, one output end of the drive type lower limb control unit performs a one-way intermittent motion; and, the other output end of the drive type lower limb control unit performs a reciprocating swing motion; wherein, the mimic femur components are in a relatively horizontal state; the angle between the foot restraint components and the mimic tibia components relatively decreases, causing the mimic tibia components to be meshed and connected with the output end of the drive type lower limb control unit performing the reciprocating swing motion, forming an electromechanical control structure for controlling the stretching of the muscles of the calf and sole of the foot; wherein, the mimic femur components are in a relatively vertical state; the angle between the mimic femur components and the mimic tibia components relatively decreases, and the output end of the drive type lower limb control unit performing the one-way intermittent motion is elastically meshed and connected with the mimic femur components, forming a load resistance control structure for controlling the obstruction of the thigh lift. When the wearer is in a sitting position, the present invention starts from the E2 starting angle by lifting the foot restraint components, causing the mimic tibia components to produce linkage, and at the same time meshing the mimic tibia components with the drive type lower limb control unit. Through the output end of the drive type lower limb control unit performing the reciprocating swing motion for operation, the mimic tibia components are driven passively. Through this mechanized operation method, when in a sitting position, the patient's calf is lifted. At the same time, after the patient's calf is lifted to a relatively horizontal position or the patient's lifting limit, the mimic tibia components cause the foot restraint components to perform further lifting work based on continuous driving. Through this setting, it forms a mechanized auxiliary stretching of the soleus muscle and hamstring muscle of the leg, etc., achieving the treatment effect of treating high muscle tension; and when in a standing position, through one output end of the drive type lower limb control unit performing a one-way intermittent motion and being meshed and driven with the mimic femur components, and based on the elastic connection at the end of the output end of the drive type lower limb control unit performing the one-way intermittent motion, an elastic meshing state at the V1 starting angle is achieved. With the drive of the output end of the drive type lower limb control unit performing the one-way intermittent motion, an elastic restoring force is formed, causing the patient to be resisted during the relative lifting process. Through this method, the anti-resistance exercise effect for low muscle tension is achieved. The switching between the two methods is based on the patient's body posture and the motion process adapted to the posture. Through this method, the treatment work for patients with lower limb diseases in two different neurology nursing works is achieved. And simultaneously based on the mechanized operation of the device and the patient's own cooperation, the work intensity of the nursing staff is effectively reduced, and the convenience of treatment is improved.

[0018] Preferably, the mimic tibia component includes a tibia meshing shaft hinged in the connection mounting seat; a tibia connecting arm is hinged to the end of the tibia meshing shaft; a parallel control arm B is hinged to the other end of the tibia meshing shaft; the tibia connecting arm and the parallel control arm B are hinged and connected by a parallel connection seat; wherein, the foot restraint component is fixedly connected with the parallel connection seat.

[0019] Preferably, the angle between the foot restraint component and the simulated tibial component is relatively reduced, so that the tibial meshing shaft is meshed with the output gear A, and the reciprocating drive motor is driven by the driving toothless bevel gear that rotates relatively in the forward direction, and the orbiting arm rotates synchronously, and the one-way meshing tooth A protrudes through the spring action, and the sharp angle of the one-way meshing tooth A is matched with the meshing drive ratchet disk to form a meshing effect, and the driving toothless bevel gear is driven to rotate, so that the meshing drive ratchet disk rotates as a whole, and the opposite toothless gear rotates in the opposite direction, and the inclined surface of the one-way meshing tooth B on the auxiliary arm is squeezed by the inclined surface of the tooth groove of the meshing drive ratchet disk, so that the one-way meshing tooth B is compressed, causing the one-way meshing tooth B to separate from the meshing drive ratchet disk; based on the relative forward and reverse rotation of the reciprocating drive motor, the output gear A is driven to perform repeated rotational motion synchronously to mechanized control of the angle change of the simulated tibial component and the foot restraint component, thereby forming an electromechanical control structure for leg muscle stretching.

Moreover, the inclined surface of the one-way meshing tooth B on the auxiliary arm is squeezed by the inclined surface of the tooth groove of the meshing driving ratchet disk, causing the one-way meshing tooth B to be compressed and separated from the meshing driving ratchet disk, forming a one-way movement of the ratchet, causing the driven meshing driving ratchet disk to rotate unidirectionally as a whole, and continuously inputting elastic torque through the unidirectional rotation when the output gear B is meshed. In this way, there is resistance to the application of elastic torque during the meshing process of the output gear B and the simulated femoral component, forming a load resistance control structure for lifting the leg.

[0021] A lower limb health rehabilitation method for neurology nursing, comprising the following steps: S100, wearing work: manually wearing the lower limb health rehabilitation device; and tightening the waist, thigh, calf and sole; S200, adjustment processing: S201, if the adjustment process of the lower limb muscle tension is performed: the wearer sits upright on the chair; then the foot restraint component is tilted up, so that the simulated tibial component is linked, and the tibial meshing shaft is meshed with the output gear A; S202, if the adjustment process of low muscle tension of lower limbs is performed: the wearer stands; then the output gear B is meshed and connected with the femoral meshing shaft by lifting the leg; S300, Rehabilitation exercise: It is driven by the driving missing-tooth bevel gear that rotates relatively forward and backward by the reciprocating drive motor. The bypass arm rotates synchronously, and the one-way meshing tooth A protrudes under the action of the spring. The tip of the one-way meshing tooth A is engaged with the meshing drive ratchet disc to form a meshing effect. With the rotation drive of the driving missing-tooth bevel gear, the whole meshing drive ratchet disc rotates. At the same time, the opposite missing-tooth gear rotates in the opposite direction. Moreover, the inclined plane of the one-way meshing tooth B on the auxiliary arm is squeezed with the tooth groove inclined plane of the meshing drive ratchet disc, causing the one-way meshing tooth B to be compressed and separated from the meshing drive ratchet disc. Based on the relative forward and reverse rotation of the reciprocating drive motor, the drive output gear A rotates repeatedly synchronously to mechanize the control of the angular changes of the mimic tibia component and the foot restraint component, forming a drive operation for stretching the leg muscles. And due to the characteristics of the ratchet structure, the driven meshing drive ratchet disc rotates unidirectionally. Through the unidirectional rotation, elastic torque is continuously input when the output gear B is in the meshed state. In this way, when the output gear B meshes with the mimic femur component, there is a resistance with elastic torque applied to perform an anti-resistance movement for lifting the leg.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the wearer is in a sitting position, the foot restraint component is used to lift the starting angle E2, causing the mimic tibia component to produce a linkage. At the same time, the mimic tibia component is meshed with the driving type lower limb control unit. Through the movement operation of the output end of the reciprocating swing movement of the driving type lower limb control unit, the mimic tibia component is driven passively. Through this mechanized operation method, the patient's calf is lifted in the sitting position. At the same time, after the patient's calf is lifted to a relatively horizontal position or the patient's lifting limit, the mimic tibia component causes the foot restraint component to perform further lifting work based on continuous driving. Through this setting, it forms a mechanical auxiliary stretching of the soleus muscle and hamstring muscle of the leg, etc., realizing the treatment effect of treating high muscle tension. And in the standing state, one output end of the driving type lower limb control unit makes a one-way intermittent movement to be meshed and driven with the mimic femur component. And based on the elastic connection at the end of the output end of the one-way intermittent movement of the driving type lower limb control unit, an elastic meshing state at the starting angle V1 is realized. With the drive of the output end of the one-way intermittent movement of the driving type lower limb control unit, an elastic restoring force is formed to cause the patient to be resisted during the relative lifting process. Through this method, the anti-resistance movement effect for low muscle tension is realized. The switching between the two methods is based on the patient's body posture and the movement process adapted to the posture. Through this method, the treatment work for lower limb diseases in two different neurological nursing works is realized. And synchronously based on the mechanized operation of the device and the patient's own cooperation, the work intensity of the nursing staff is effectively reduced, and the convenience of treatment is improved.

[0023] 2. The present invention is provided with a meshing drive ratchet disc in cooperation with a winding arm, a one-way meshing tooth A, an auxiliary arm, and a one-way meshing tooth B, forming a staggered ratchet meshing structure with double meshing points. This method is driven by a driving toothless bevel gear rotating relatively forward, and the winding arm rotates synchronously. Moreover, the one-way meshing tooth A protrudes due to the action of a spring, and the sharp corner of the one-way meshing tooth A fits with the meshing drive ratchet disc to form a meshing effect. In cooperation with the rotation drive of the driving toothless bevel gear, the entire meshing drive ratchet disc rotates, and at the same time, the opposing toothless gear rotates in the opposite direction. At this time, the inclined surface of the one-way meshing tooth B on the auxiliary arm is squeezed against the tooth groove inclined surface of the meshing drive ratchet disc, causing the one-way meshing tooth B to be compressed and separated from the meshing drive ratchet disc; based on the forward and reverse rotations of the reciprocating drive motor relative to each other, the drive output gear A synchronously makes repeated rotational movements, forming a mechanized control of the angular changes of the mimetic tibia component and the foot restraint component, and forming a driving operation for stretching the leg muscles; and due to the characteristics of the ratchet structure, the entire driven meshing drive ratchet disc rotates unidirectionally. Through unidirectional rotation, elastic torque is continuously input while the output gear B is in the meshed state. In this way, when the output gear B meshes with the mimetic femur component, there is a resistance caused by the application of elastic torque, so as to perform a resistance exercise for lifting the leg. Through this method and the different degrees of twisting and winding of the scroll spring, the applied resistance is also different. Through this method, the mechanical variable-stage resistance adjustment is effectively realized to adapt to patients with different low muscle tensions. BRIEF DESCRIPTION OF THE DRAWINGS

An elastic force is always applied to the femoral hinge shaft 301 and the parallel control arm A303, so that the meshing tooth end of the femoral meshing shaft 304 has a rotational torque and a rotation buffer space, and it is not a rigid contact, thereby effectively improving the protection effect of the lower limb health rehabilitation device.

[0028] In an embodiment of the present invention, the driven lower limb control unit 4 includes a connection mounting base 401 arranged at the bottom of the femur connecting arm 302; an output cavity and a driving cavity are sequentially arranged axially in the connection mounting base 401; a driving missing-tooth bevel gear 402 is sequentially arranged axially relative to the axis position of the driving cavity inside the driving cavity; wherein, a bypass arm 4021 is arranged at the end of the driving missing-tooth bevel gear 402; a one-way meshing tooth A 4022 is elastically arranged at the end of the bypass arm 4021 relatively close to the outer extension of the driving cavity.

[0029] In an embodiment of the present invention, a counter missing-tooth gear 403 rotatably connected to the connection mounting base 401 is arranged at the end of the bypass arm 4021; an auxiliary arm 4031 is arranged on the side of the counter missing-tooth gear 403; a one-way meshing tooth B 4032 is elastically arranged at the end of the auxiliary arm 4031 relatively close to the outer extension of the driving cavity; the driving missing-tooth bevel gear 402 and the counter missing-tooth gear 403 are meshed and connected through a linkage driving gear 404 arranged on the connection mounting base 401. In the present invention, the linkage driving gear 404 is arranged to mesh with the driving missing-tooth bevel gear 402 and the counter missing-tooth gear 403 respectively, and the opposite rotation effect of the driving missing-tooth bevel gear 402 and the counter missing-tooth gear 403 is realized based on the transmission principle of bevel gears.

[0030] In an embodiment of the present invention, a reciprocating drive motor 405 is disposed relative to the outside of the connection mounting base 401 to drive the missing-tooth bevel gear 402; an output gear A4033 is disposed at the end of the opposing missing-tooth gear 403 relative to the inside of the output cavity; a meshing drive ratchet disc 407 is rotatably disposed outside the opposing missing-tooth gear 403; an output gear B4071 is rotatably disposed at the end of the meshing drive ratchet disc 407; and the output gear B4071 is elastically connected to the meshing drive ratchet disc 407 through a scroll spring. Through the arrangement of the meshing drive ratchet disc 407 in cooperation with the circumferential arm 4021, the one-way meshing tooth A4022, the auxiliary arm 4031, and the one-way meshing tooth B4032, a staggered ratchet meshing structure with double meshing points is formed. In this way, the missing-tooth bevel gear 402 that rotates relatively in the forward direction is used for driving, the circumferential arm 4021 rotates synchronously, and the one-way meshing tooth A4022 protrudes due to the action of the spring. The tip of the one-way meshing tooth A4022 is fitted with the meshing drive ratchet disc 407 to form a meshing action. In cooperation with the rotation drive of the missing-tooth bevel gear 402, the entire meshing drive ratchet disc 407 rotates. At the same time, the opposing missing-tooth gear 403 rotates in the opposite direction. At this time, the inclined surface of the one-way meshing tooth B4032 on the auxiliary arm 4031 is pressed against the inclined surface of the tooth groove of the meshing drive ratchet disc 407, causing the one-way meshing tooth B4032 to be compressed and separated from the meshing drive ratchet disc 407. Based on the forward and reverse rotation of the reciprocating drive motor 405, the output gear A4033 is driven to rotate repeatedly synchronously, forming a mechanical control of the angle change of the mimetic tibia assembly 5 and the foot restraint assembly 6, and forming a driving operation for stretching the leg muscles. And due to the characteristics of the ratchet structure, the entire driven meshing drive ratchet disc 407 rotates in one direction. Through one-way rotation, elastic torque is continuously input when the output gear B4071 is in the meshed state. In this way, when the output gear B4071 meshes with the mimetic femur assembly 3, a resistance caused by the elastic torque application is generated to perform a resistance exercise for lifting the leg. Through this method and the different twisting and winding of the scroll spring, the applied resistance is also different. Through this method, the mechanical variable-stage resistance adjustment is effectively realized to adapt to patients with different low muscle tensions.

[0032] In an embodiment of the present invention, during the movement of the foot restraint assembly 6 with a relatively reduced included angle with the mimetic tibia assembly 5, the tibia meshing shaft 501 meshes with the output gear A4033. Moreover, the reciprocating drive motor 405 drives the driving missing-tooth bevel gear 402 to rotate forward, the bypass arm 4021 rotates synchronously, and the one-way meshing tooth A4022 protrudes by the action of a spring. The tip of the one-way meshing tooth A4022 forms a meshing action with the meshing drive ratchet disc 407. With the rotation drive of the driving missing-tooth bevel gear 402, the entire meshing drive ratchet disc 407 rotates. At the same time, the opposing missing-tooth gear 403 rotates in the opposite direction. Moreover, the inclined surface of the one-way meshing tooth B4032 on the auxiliary arm 4031 presses against the tooth groove inclined surface of the meshing drive ratchet disc 407, causing the one-way meshing tooth B4032 to be compressed and separated from the meshing drive ratchet disc 407. Based on the forward and reverse rotation of the reciprocating drive motor 405 relative to each other, the output gear A4033 rotates repeatedly synchronously to mechanize the control of the angle changes of the mimetic tibia assembly 5 and the foot restraint assembly 6, forming an electromechanical control structure for stretching the leg muscles.

[0033] In an embodiment of the present invention, during the movement of the mimetic femur assembly 3 with a relatively reduced included angle with the mimetic tibia assembly 5, the output gear B4071 meshes and connects with the femur meshing shaft 304. Moreover, the reciprocating drive motor 405 drives the driving missing-tooth bevel gear 402 to rotate forward, the bypass arm 4021 rotates synchronously, and the one-way meshing tooth A4022 protrudes by the action of a spring. The tip of the one-way meshing tooth A4022 forms a meshing action with the meshing drive ratchet disc 407. With the rotation drive of the driving missing-tooth bevel gear 402, the entire meshing drive ratchet disc 407 rotates. At the same time, the opposing missing-tooth gear 403 rotates in the opposite direction. Moreover, the inclined surface of the one-way meshing tooth B4032 on the auxiliary arm 4031 presses against the tooth groove inclined surface of the meshing drive ratchet disc 407, causing the one-way meshing tooth B4032 to be compressed and separated from the meshing drive ratchet disc 407, forming a ratchet one-way movement, causing the entire driven meshing drive ratchet disc 407 to rotate in one direction. Through the one-way rotation, elastic torque is continuously input when the output gear B4071 is in the meshed state.

Wearing work: Manually wear the lower limb health rehabilitation device; and tighten the waist, thigh, calf, and sole of the foot. S200. Adjustment process: S201. If adjusting the high lower limb muscle tension: the wearer sits upright on the chair; then lift up through the foot restraint component 6, causing the mimic tibia component 5 to have a linkage, and at the same time making the tibia meshing shaft 501 mesh with the output gear A4033; S202. If adjusting the low lower limb muscle tension: the wearer stands; then cause the output gear B4071 to mesh with the femur meshing shaft 304 through the leg-lifting action; S300. Rehabilitation exercise: drive the reciprocating drive motor 405 to rotate relative to the forward-rotating driving missing-tooth cone gear 402, the bypassing arm 4021 rotates synchronously, and the one-way meshing tooth A4022 protrudes by the action of the spring. The tip of the one-way meshing tooth A4022 is engaged with the meshing driving ratchet disc 407 to form an engagement effect. With the rotation drive of the driving missing-tooth cone gear 402, the whole meshing driving ratchet disc 407 rotates, and at the same time, the opposing missing-tooth gear 403 rotates in the opposite direction. Moreover, the slope of the one-way meshing tooth B4032 on the auxiliary arm 4031 is squeezed against the tooth groove slope of the meshing driving ratchet disc 407, causing the one-way meshing tooth B4032 to be compressed and separated from the meshing driving ratchet disc 407; based on the forward and reverse rotation of the reciprocating drive motor 405 relative to each other, drive the output gear A4033 to rotate repeatedly synchronously, to mechanize the control of the angle change of the mimic tibia component 5 and the foot restraint component 6, forming a driving operation for stretching the leg muscles; and due to the characteristics of the ratchet structure, cause the driven meshing driving ratchet disc 407 to rotate unidirectionally, and continuously input elastic torque during the meshing state of the output gear B4071 through unidirectional rotation. In this way, when the output gear B4071 meshes with the mimic femur component 3, there is a resistance caused by the application of elastic torque to perform a resistance exercise for lifting the leg.
