Description

Auxiliary power-assisted training instrument for nerve rehabilitation

Technical Field

The invention relates to the field of medical instruments, in particular to an auxiliary power-assisted training instrument for nerve rehabilitation.

Background

The bridge type movement is a common training method in medical rehabilitation training, is beneficial to improving the control and coordination capacity of the pelvis on the lower limbs, is the basis of successful standing and walking, can well train hip extension muscles and start gluteus, and belongs to simple and effective actions. Common body postures include excessive forward inclination of the hip joint, making it abnormally difficult to extend the hip joint and initiate gluteal muscle function, so bridge movements can break this difficult pattern. The bridge type movement is the most basic training for paralyzed patients and is also the premise and the basis for all movement exercises.

The paralyzed patient cannot finish motion training independently due to insufficient muscle strength, so the method is generally carried out in a mode of carrying out auxiliary training for a rehabilitation teacher or family members of the patient clinically. During training, a patient lies on the back on the bed surface, the two legs are bent, one hand of an assistant person presses the two feet of the patient to keep the two feet fixed, the other hand drags the hip of the patient downwards to be close to the position of the thigh to lift upwards, the patient exerts force independently to add the lifting force of the assistant person to lift the hip of the patient upwards to the maximum position, and after a certain period of time, the hip is lowered to the bed surface.

However, this method is heavily dependent on the rehabilitation staff or other assistant staff, and the physical strength of the assistant staff is a great test when the patient is weak in self-strength. In addition, since a single assistant can only assist one patient at a time, it is far from satisfying the rehabilitation needs of many patients for the rehabilitation therapist.

In the prior art, there are some means to assist in lifting. However, these lifting devices can only provide assistance in a single direction, such as vertical or in a particular linear direction. However, when the patient performs bridge type movement, the movement tracks of the thighs and the buttocks of the patient are changed and nonlinear, the movement tracks are approximately arc-shaped movement tracks along a circle center, the auxiliary lifting of the hands of the rehabilitation teacher can be synchronously adapted along with the movement tracks of the patient, the auxiliary lifting in a single direction cannot effectively simulate the auxiliary actions of the rehabilitation teacher, the skin can be pulled and the pain and other uncomfortable symptoms can be caused due to the displacement generated between the lifting device and the body of the patient in the lifting process, meanwhile, the lifting device cannot be effectively attached to the body of the patient, and therefore a better supporting effect is provided.

Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

The first embodiment is as follows:

as shown in fig. 1 to fig. 2, an assisted training apparatus for nerve rehabilitation provided in an embodiment of the present invention includes a bed plate 10, and further includes:

two adjusting devices are arranged and are respectively positioned on two sides of the bed plate 10, and each adjusting device comprises an adjusting bracket and a rotating shaft 32;

the adjusting bracket comprises a first adjusting bracket 30 and a second adjusting bracket 31, as shown in fig. 3, the first adjusting bracket 30 and the second adjusting bracket 31 are both in an arc structure and are located on the same circumferential track, the first adjusting bracket 30 and the second adjusting bracket 31 are respectively provided with a first adjusting groove 301 and a second adjusting groove, and the extending tracks of the first adjusting groove 301 and the second adjusting groove are located on the same circumferential track; as shown in fig. 6, a first adjusting tooth 302 and a second adjusting tooth are respectively disposed in the first adjusting groove 301 and the second adjusting groove, the disposing directions of the first adjusting tooth 302 and the second adjusting tooth are opposite, that is, the first adjusting tooth 302 is disposed on a side wall of the first adjusting groove 301, taking the viewing angle of fig. 6 as an example, which is the viewing angle when the first adjusting bracket 30 is viewed from the front, the first adjusting tooth 302 is disposed on a side wall on the right side of the first adjusting groove 301, and correspondingly, the second adjusting tooth is disposed on a side wall on the left side of the second adjusting groove;

two ends of the rotating shaft 32 are slidably arranged in the first adjusting groove 301 and the second adjusting groove respectively, the ends of the rotating shaft 32 corresponding to the first adjusting groove 301 and the second adjusting groove are provided with a first steering gear 321 and a second steering gear respectively, namely the first steering gear 321 and the second steering gear are arranged at two ends of the rotating shaft 32 respectively and are positioned in the first adjusting groove 301 and the second adjusting groove respectively, the first steering gear 321 is meshed with the first adjusting tooth 302, and the second steering gear is meshed with the second adjusting tooth; when the rotating shaft 32 rotates, both ends of the rotating shaft slide along the first adjusting groove 301 and the second adjusting groove, respectively, so that the rotating shaft 32 rotates clockwise or counterclockwise.

The supporting belt 22, as shown in fig. 1, the supporting belt 22 is set up on two rotating shafts 32, and when the supporting belt 22 moves, the rotating shafts 32 are driven to rotate; and the number of the first and second groups,

and a driving means for lengthening or shortening the length of the support bands 22 between the two rotating shafts 32 to move the support bands 22. Specifically, as shown in fig. 5, the driving device includes a driving motor 20 and a roller 21, the driving motor 20 is fixedly disposed on the bed board 10, and the driving motor 20 is used for driving the roller 21 to rotate; both ends of the support belt 22 are fixedly coupled to both sides of the drum 21, respectively, and the support belt 22 is tightened or loosened when the drum 21 rotates. Taking fig. 5 as an example, when the roller 21 rotates, the supporting belt 22 is wound on the roller 21, so that the effective working length of the supporting belt 22 is shortened, and at this time, the supporting belt 22 moves to drive the rotating shaft 32 to rotate (when in operation, a human body presses on the supporting belt 22, so that sufficient friction force can be generated). In the process, the support bands 22 are shortened, and the support bands 22 located between the two rotation shafts 32 are pulled to be lifted, thereby giving an auxiliary lifting force to the patient.

In order to make the movement of the support belt 22 smoother, guide rollers 13 for guiding the support belt 22 are further provided at both sides of the bed plate 10.

In operation, as shown in fig. 3, initially, the patient is in a supine position, the feet are fixed, the thighs are placed on the support bands 22, the support band 22 between the two rotating shafts 32 is at a lower position, when the rotating shafts 32 rotate in a certain direction, the first steering gear 321 and the second steering gear at the two ends are simultaneously driven to rotate, the first steering gear 321 is engaged with the first adjusting tooth 302, the first steering gear 321 rotates to be matched with the first adjusting tooth 302 by taking the first steering gear 321 rotating counterclockwise as an example, the first steering gear 321 generates an extending track along the first adjusting groove 301 and moves downward, that is, the right end of the rotating shaft 32 moves clockwise, and conversely, the second steering gear rotates counterclockwise and is matched with the second adjusting tooth, because the position of the second adjusting tooth is opposite to the position of the first adjusting tooth 302, in the process, the second steering gear is moved upward in a clockwise direction to finally effect a clockwise rotation of the rotation shaft 32, thereby moving to the state shown in fig. 4. This in-process, support the area 22 and draw and can upwards rise, and because the rotation of pivot 32, can make its support position to supporting area 22 change, make supporting area 22 under the support of pivot 32, can produce the upset, its rotation angle is roughly the same with human rotation angle, thereby make supporting area 22 can remain the state with the laminating of patient's thighs all the time, thereby provide better supporting effect, avoid human angle to produce the change and support area 22 local atress that area 22 did not produce the change and cause, the supporting effect variation to the patient, supporting part pressure grow, cause the patient to be uncomfortable.

Example two:

in order to avoid the damage of the equipment caused by the excessive force applied to the two ends of the supporting belt 22 due to the excessive number of continuous rotation turns of the roller 21, the supporting belt 22 is not lifted to the maximum height in practical use. This, in turn, causes the support bands 22 to continue to rise and the patient's foot to become immobilized, causing the patient's lower leg to be excessively pulled and damaged.

Therefore, in the present embodiment, as shown in fig. 1, 2 and 8, two straps 11 for fixing both feet are provided on the bed plate 10. The device further comprises a detection device which comprises two pressure sensors 12 and a processor, wherein the positions of the two pressure sensors 12 correspond to the positions of the two binding bands 11 respectively; the pressure sensor 12 and the driving motor 20 are connected to the processor through signals.

In operation, the feet of the patient are placed on the two pressure sensors 12, and the pressure sensors 12 detect signals and send the signals to the processor. During the continuous operation of the device, the support belt 22 rises, when the leg of the patient is lifted to the highest position, the feet are pulled, so that the feet gradually separate from the pressure sensors 12, that is, the pressure sensors 12 detect that the pressure is gradually reduced and continuously send the pressure to the processor, when the pressure is reduced to a preset threshold value, the processor judges that the support belt 22 has moved to the optimal position, and the processor controls the driving motor 20 to stop working or perform reverse rotation, so that the body position of the patient returns to the initial position. It will be appreciated that when the motor is rotated in the reverse direction, the portion of the support belt 22 located between the two shafts 32 will sink due to the weight of the human body, and will move in the opposite direction to the first embodiment, thereby returning the patient to the initial position.

Example three:

on the basis of the second embodiment, since the rotating shaft 32 is inclined after rotating, the supporting bands 22 are also inclined, and since the center of the human body is on one side of the supporting bands 22, the human body tends to slide, so that the supporting bands 22 slide obliquely on the rotating shaft 32 (slide towards the lower side of the rotating shaft 32), which affects the normal operation of the instrument.

Therefore, in this embodiment, as shown in fig. 7, 9 and 10, the rotating shaft 32 is provided with a driving roller 33 at a position corresponding to the support belt 22, the driving roller 33 is provided with a first driving tooth, and one side of the support belt 22 is provided with a second driving tooth, and the first driving tooth is engaged with the second driving tooth.

Further, the driving roller 33 is provided with an anti-deviation groove, an extending track of the anti-deviation groove is a circular structure, and the supporting belt 22 is provided with an anti-deviation block corresponding to the anti-deviation groove, and the anti-deviation block is slidably disposed in the anti-deviation groove.

Through the arrangement of the anti-cheating groove and the anti-deviation block, the supporting belt 22 can be pulled by the anti-deviation block when sliding, so that deviation cannot be generated, and abnormal sliding of the supporting belt 22 is avoided.

Example four:

in the third embodiment, the supporting effect of the single deviation-preventing groove and the deviation-preventing block is limited, and the deviation-preventing block is easy to crack and damage after being used for a long time or stressed. Since the support band 22 is fast and the support band 22 is easy to turn when it is pulled by a human body, in the embodiment, the deviation-preventing groove includes a first deviation-preventing groove 331 and a second deviation-preventing groove 332, the deviation-preventing block includes a first deviation-preventing block 221 and a second deviation-preventing block 222, and the cross sections of the first deviation-preventing groove 331, the second deviation-preventing groove 332, the first deviation-preventing block 221 and the second deviation-preventing block 222 are in a trapezoidal structure. So that the anti-deviation effect is better.

Further, as shown in fig. 10, when two or more deviation-preventing grooves and deviation-preventing blocks are adopted, the fatigue strength of the support belt 22 can be improved, and the supporting effect can be improved, but because the rotating shaft 32 is arranged obliquely during the actual operation, most of the pulling force and gravity of the human body on the support belt 22 are concentrated on the lower side of the support belt 22, fig. 7 shows the stress condition of the support belt 22 during the operation, the stress on the second deviation-preventing block 222 is greater than the stress on the first deviation-preventing block 221, as shown in fig. 10, the resistance condition of the second deviation-preventing groove 332 on the second deviation-preventing block 222 is shown, the circle mark in the figure is prone to stress concentration and cracking damage, and because the stress on the first deviation-preventing block 221 is less than the stress on the second deviation-preventing block 222, the two can not be stressed equally, the second deviation-preventing block 222 has a shorter life than the first deviation-preventing block 221, which causes unnecessary waste, and also does not facilitate the operation of the instrument, therefore the embodiment further comprises:

as shown in fig. 9, the fatigue preventing device includes a push plate 23 and a yielding spring 24, the yielding spring 24 is sleeved on the driving roller 33, and the push plate 23 is in an annular structure and sleeved on the driving roller 33;

the rotating shaft 32 is obliquely arranged, the first deviation preventing groove 331 is higher than the second deviation preventing groove 332, and the width of the second deviation preventing groove 332 is larger than that of the first deviation preventing groove 331; the anti-fatigue device is located in the second anti-deviation groove 332 and located on one side of the second anti-deviation block 222 away from the first anti-deviation block 221, the push plate 23 is slidably disposed in the anti-deviation groove, one end of the abdicating spring 24 is fixedly connected to the push plate 23, the other end of the abdicating spring is fixedly connected to the anti-deviation groove, and one side of the second anti-deviation block 222 away from the first anti-deviation block 221 abuts against the push plate 23.

When supporting the area 22 atress, the second prevents inclined to one side piece 222 owing to have certain activity space, can produce the right, decurrent displacement, and first prevent inclined to one side piece 221 is because the space is restricted in this process, can receive the resistance in advance, thereby share partial load, and along with the continuous rotation of pivot 32, the power that the second prevents inclined to one side piece 222 received increases, compression push pedal 23, make the spring 24 that gives way produce the compression, the second prevents inclined to one side piece 222 atress grow, thereby make the resistance that receives between first prevent inclined to one side piece 221 and the second prevent inclined to one side piece 222 can be more balanced, effectively prolong the life of supporting area 22.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
