[0031] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.
[0032] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.
[0033] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0034] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.
[0035] In view of the fact that the current rehabilitation training devices are difficult to achieve a better training effect for the upper limb and hand activity functions, the utility model drives the upper limb to complete the abduction and adduction activities of the shoulder joint through the automatic extension and retraction of the horizontal frame; drives the upper limb and hand to complete the flexion and extension activities of the elbow joint through the rotation of the horizontal frame; and can fully train the activity functions of the upper limb and hand. The movement frequency of the horizontal frame is adjusted by controlling the power device, and no manual intervention by the therapist is required. Rehabilitation training is carried out specifically for the activity functions of the upper limb and hand, and the training is sufficient to improve the efficiency of upper limb rehabilitation.
[0036] Figure 1 , Figure 2 and Figure 3The upper limb rehabilitation trainer of this embodiment is shown, which mainly includes a base 10, a vertical pole 11, a power device 12, a horizontal frame 13, a connecting belt 14 and a handle 15. A lockable roller 10a is installed at the bottom end of the base 10, which is easy to move and has a wide range of application scenarios. It can be used in various rehabilitation treatment areas at home, in wards, and in hospitals. The vertical pole 11 is installed on the base 10 and can adjust the height. It includes an inner pole 11a and an outer pole 11b. The outer pole 11b is inserted into the base 10, and the inner pole 11a is buckled on the outer pole 11b. Several positioning holes are dug on the inner pole 11a, and threaded holes are dug on the outer pole 11b. Bolts 11c are screwed into the threaded holes and then inserted into the positioning holes at different positions on the inner pole 11a, so as to adjust the length of the inner pole 11a extending out of the outer pole 11b. In other words, the above-mentioned threaded holes, bolts and fixing holes constitute an adjustment device for adjusting the height of the vertical pole. It has a wide range of indications and can be applied to bedridden patients. In one example, the vertical pole 11 is a single pole, and a thread is provided at the bottom of the vertical pole 11 , and the height of the vertical pole 11 can be adjusted linearly through a rack in the base 10 .
[0037] By adjusting the height of the upright pole to a suitable height for beds and chairs, it can be conveniently used for bedridden patients. For patients who use wheelchairs or can sit alone in chairs, the height of the upright pole can also be adjusted for treatment.
[0038] In order to facilitate the lifting of the inner rod 11a, a lifting assist spring 11d is also installed inside the outer rod 11b, and the lifting assist spring 11d is connected to the bottom of the inner rod 11a. Under the action of the lifting assist spring 11d, it is easier to pull out the inner rod 11a from the outer rod 11b.
[0039] A power device is installed on the vertical pole 11, and the cross frame 13 is fixed on the power device. One end of the connecting belt 14 is movably connected to the free end of the cross frame 13, and the other end is installed with a handle 15 for the patient to grasp and fix. Driven by the power device, the cross frame 13 can move linearly and / or rotate around the connection point between the cross frame 13 and the power device, thereby actively adjusting the position of the handle 15. When the cross frame 13 rotates, the handle 15 changes its height and front and back position under the action of the power device, and can complete the flexion and extension of the elbow joint, and the flexion, adduction, and abduction of the shoulder joint. When the cross frame 13 moves linearly, the handle 15 changes its front and back position under the action of the power device, and can complete the flexion, adduction, and abduction of the shoulder joint.
[0040] In this embodiment, the power device is a motor 12. A base plate 12a is fixed on the top of the vertical pole 11, and the motor 12 is fixed on the base plate 12a. An arc-shaped protective cover 12b is also installed on the base plate 12a, and the protective cover 12b and the base plate 12a form a sealed space, and the motor 12 is covered in the sealed space. Among them, the motor 12 is preferably a stepper motor. According to the control signal, the output shaft of the stepper motor can move back and forth or rotate, and can drive the cross frame 13 to move linearly or rotate; when the motor 12 is an ordinary motor, the output shaft of the motor can only rotate, and the cross frame 13 can only rotate accordingly; when the motor 12 is a linear reciprocating motor, the output shaft of the motor can only move back and forth linearly, and the cross frame 13 can only move linearly accordingly.
[0041] The horizontal frame 13 includes an orthogonal first rod 13a and a second rod 13b, and the first rod 13a is fixed on the output shaft of the motor 12. However, it is not limited to the orthogonal manner. For example, the angle between the first rod 13a and the second rod 13b can also be an obtuse angle. By designing the structure of the first rod 13a and the second rod 13b, the position movement range of the handle 15 is larger, and the training effect is improved. However, the structure of the horizontal frame 13 is not limited. In one example, the horizontal frame 13 is a single rod fixed on the output shaft of the motor 12.
[0042] By fixing the cross frame on the power device and setting different movement frequencies and movement methods for the power device, a variety of training programs can be generated for the activity functions of the upper limbs and hands, so that the training is more comprehensive and better training effects are obtained.
[0043] A pulley (not shown) is installed on the free end of the horizontal frame 13, and a flexible connecting belt 14 is fixed on the pulley. The other end of the connecting belt 14 is connected to a handle 15, and the handle 15 is a triangular frame for the palm to hold. When the horizontal frame 13 rotates, the height and horizontal position of the handle 15 will change; when the horizontal frame 13 moves forward and backward, the horizontal position of the handle 15 also moves forward and backward. The handle 15 drives the entire arm to move, passively assists the muscles to stretch and relax, and promotes muscle strength training. In this embodiment, a flexible connecting belt 14 is used. When in use, the connecting belt 14 can bend and twist to avoid accidental injuries to the upper limbs and hands during training.
[0044] Although the connection belt 14 is installed on the pulley in this embodiment, the way in which the connection belt 14 is movably connected to the free end of the horizontal frame 13 is not limited, and specifically, the connection belt 14 can be sleeved on the free end of the horizontal frame 13 or a pulley or a bearing is installed on the free end of the horizontal frame 13, and then the connection belt 14 is fixed on the pulley. After the connection belt 14 is movably connected to the free end of the horizontal frame 13, when the horizontal frame 13 rotates, the end of the connection belt 14 connected to the horizontal frame 13 will not curl or tangle.
[0045] A controller 10b is installed inside the base 10, and the controller 10b is electrically connected to the motor 12 to send a control signal to the motor 12. In order to facilitate control, a remote controller is also provided in this embodiment, and the wireless signal of the remote controller is received by the controller 10b, and the wireless signal is converted into a control signal to realize the functions of switching the motor 12 on and off and controlling the operating gear of the motor 12. There is no restriction on the installation position of the controller 10b, and the controller 10b can also be made into a control box and installed on the vertical pole 11, or the control box can be placed next to the upper limb rehabilitation trainer as an independent component. The controller is electrically connected to the power device, and can change the movement frequency or movement mode of the power device, such as driving the horizontal frame to rotate or move in a straight line. It has a high degree of automation and reduces manual dependence.
[0046] like Figure 4 As shown, in some embodiments, the upper limb rehabilitation trainer also includes an auxiliary device 20 consisting of an inflatable device 21, an air bag 22 worn on the forearm, and an air tube 23. For the convenience of description, the base 10, the upright pole 11, the power device, the cross frame 13, the connecting belt 14, and the handle 15 are collectively referred to as the main unit, corresponding to the auxiliary device 20. Among them, one end of the air tube 23 is connected to the inflatable device 21, and the other end is connected to the air bag 22. The inflatable device 21 inflates and deflates the air bag 22 through the air tube 23, which is equivalent to a "muscle pump" to achieve muscle contraction and relaxation, achieve the effect of pressing the upper limbs, promoting blood circulation, and promoting the recovery of upper limb muscle strength.
[0047] The inflatable device 21 in this embodiment is provided with a display screen 21a and a control panel 21b, and a handle 21c is also provided at the top of the inflatable device 21. The inflatable device 21 is equipped with a main control panel and an air pump, and the main control panel receives an electrical signal from the control panel 21b to turn on or off the air pump. The air circuit tube 23 is a multi-position air circuit tube, which contains 4 or 8 heating resistors, and can heat the gas filled into the airbag 22 to promote blood circulation in the upper limbs. The airbag 22 is sleeve-shaped, and the upper arm can be inserted into the airbag 22. The airbag 22 is a three-layer structure, the outer layer is not elastic, the inner layer is elastic, and the outer layer and the inner layer are sealed between the inflatable layer. The air circuit tube 23 is connected to the inflatable layer, and the inflatable layer can be inflated or deflated.
[0048] In order to achieve the contraction and relaxation of the palm muscles, the auxiliary device 20 also includes a glove 24, which is connected to the airbag 22 to form a glove sleeve, which is easy to wear. Accordingly, the glove 24 is also a three-layer structure. When inflated, pressure is generated to promote venous return of the fingers and forearms, and then deflated to relax the fingers and forearms. Repeated operations can improve edema of the hands and upper arms. Adhesives are also provided at the index finger of the glove 24 and / or the wrist of the glove, so that it is more firm, non-slip and safer to put on the glove 24 to grab the handle 15. A ring is also provided at the wrist of the glove 24. When the ring is tightened, the glove opening of the glove 24 is contracted to prevent the glove 24 from slipping off the palm. It is easy to understand that an air inlet valve and an air outlet valve are provided on the glove sleeve.
[0049] The main unit can be used alone or in combination with auxiliary equipment. When used alone, upper limb strength training and recovery can be performed separately according to usage needs. When used in combination, for upper limbs that have not been trained for a long time, muscle strength recovery can be performed first (using air bags and gloves for warming massage to promote blood circulation); to achieve a proper warm-up effect; then you can grasp the handle and control the arm movement speed according to actual exercise needs; after completing muscle strength training, continue to use air bags for massage to assist muscle strength recovery, and adjustments can be made for muscle strength recovery at different stages.
[0050] In summary, by controlling the power device, the cross frame drives the handle to move linearly and / or rotate, which is highly automated and reduces manual dependence; the operation is simple and convenient; it can complete elbow flexion and extension, shoulder flexion, adduction, and abduction, improve joint mobility, and avoid complications such as shoulder pain and joint restriction. By controlling the inflation and deflation of the airbag in the glove sleeve, the hand and forearm are lightly cyclically pressurized, which can reduce edema of the hand and upper arm and promote blood and lymph return.
[0051] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
