Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a joint rehabilitation training device. Background Art

[0002] Traditional rehabilitation therapies help restore motor function and improve injuries, but they rely on therapists' experience, require many therapists, and are expensive. With the continuous development of robot technology, some rehabilitation robots have been developed to help stroke survivors restore motor function. Rehabilitation robots can not only effectively reduce the burden on medical staff, assist patients in rehabilitation training in a long-term, stable, and objective manner, but also provide a variety of accurate quantified rehabilitation training data, facilitating medical staff to formulate more reasonable training plans for patients based on these feedback data.

[0003] Prior art document 1, such as the patent with the application number CN202223288574.2 and the publication (announcement) number CN219091012U, discloses an arm rehabilitation training device, which is convenient for adjusting the stretching intensity of arm rehabilitation training, so as to facilitate patients to carry out targeted rehabilitation training according to their own arm rehabilitation conditions. However, the above patent is applicable to patients with freely movable elbow joints for rehabilitation exercises. Some patients cannot move their elbow joints by themselves due to their own reasons and need doctors to help them gradually move the joints.

[0004] In view of the above situation, prior art document 2, a patent with the patent number CN202420172002.8, is an arm rehabilitation training device that can passively exercise the elbow joint of patients and is applicable to patients whose arms cannot rotate by themselves; it can be fixed to the edge of the bed or other positions as a whole for training, so that the patient's arm has support and will not droop, avoiding accidental injuries; it has a simple structure and high safety. However, the structure of document 2 is bulky and not applicable for use during the patient's movement.

[0005] In summary, the existing arm rehabilitation training devices in the prior art cannot meet the arm rehabilitation training needs of patients in different situations. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a joint rehabilitation training device, which solves the problem that the existing arm rehabilitation training devices in the prior art cannot meet the arm rehabilitation training needs of patients in different situations.

[0007] The utility model is realized as follows: a joint rehabilitation training device includes a first support member, a second support member, a transmission mechanism, and a driving mechanism. The first support member is rotatably connected to the second support member through a rotating shaft. The rotating shaft is connected to the driving mechanism through the transmission mechanism, and there is a shaft-hole fit between the driving mechanism and the transmission mechanism.

[0008] When the user is training without the need to move, such as when sitting or lying down, the upper arm and forearm of the arm are respectively attached to the first support member and the second support member. The first support member and the second support member with the transmission mechanism are connected to the drive mechanism through the shaft-hole fit. Then the drive mechanism is started, and the rotating shaft rotates to drive the first support member and the second support member to rotate, thereby completing the passive training of the joint. When the user needs to move, it is not convenient to carry the drive mechanism. For example, when going to the toilet, only need to lift the arm and the shaft can be disengaged from the hole, and the drive mechanism can be detached, reducing the weight of the training device and facilitating the user's free movement, such as going out for a walk. In summary, the rehabilitation training device in the present invention can meet the different needs of users, is not restricted by the rehabilitation training device, and the user can move freely. Moreover, the drive mechanism can be placed on the support platform for use, reducing the load on the user.

[0009] The drive mechanism is placed below the transmission mechanism and is shaft-hole fitted at the same time. When the active drive of the drive mechanism is not required, only by lifting the arm, the disengagement of the shaft hole can be completed, which is convenient and fast. When the motor drive is not required, the load of the drive mechanism is removed, which can reduce the requirements for the user.

[0010] A further technical solution of the present invention is that the drive mechanism includes a double-shaft motor and a synchronous pulley. The output shafts at both ends of the double-shaft motor are respectively connected to the synchronous pulleys through synchronous belts. A drive shaft is provided on the synchronous pulley. The drive shaft is placed on both sides of the first support member and the second support member and is connected to the rotating shaft through a transmission mechanism.

[0011] After the double-shaft motor is started, the output shafts at both ends rotate, drive the synchronous pulleys to rotate through the synchronous belts, and the drive shafts on the synchronous pulleys rotate. The drive shaft is connected to the rotating shaft through a transmission mechanism, thereby driving the rotating shaft to rotate, realizing the rotation of the first support member and the second support member, and achieving the effect of joint rehabilitation training. In the present invention, one motor is used to drive the rotating parts on both sides of the first support member and the second support member to rotate synchronously. The first support member and the second support member are stable in movement, light in weight and small in volume.

[0012] A further technical solution of the present invention is that the drive shaft is perpendicular to the rotating shaft, and the drive shaft is connected to the rotating shaft through a transmission mechanism.

[0013] The drive shaft is perpendicular to the rotating shaft and is connected through a transmission mechanism. The transmission mechanism is shaft-hole fitted with the drive shaft. When motor drive training is required, only need to align the transmission mechanism and put it down on the drive shaft. When the user needs to move, or when the drive mechanism is not required for other purposes, only by lifting the arm, the shaft and hole disengagement of the transmission mechanism and the drive mechanism can be completed, which is convenient and fast to use.

[0014] A further technical solution of the present utility model is that a receiving groove is formed between the first support member and the second support member, and the rotational connection between the first support member and the second support member is disposed on both sides of the receiving groove.

[0015] The rotational connection is on both sides of the receiving groove, and the receiving groove between the first support member and the second support member is used to accommodate the joint during joint movement, avoiding friction between the joint and the rigid structure, and having high comfort.

[0016] A further technical solution of the present utility model is that detachable binding straps are provided on both the first support member and the second support member.

[0017] During use, the user fits the upper arm and the lower arm of the arm to the first support member and the second support member respectively. In order to ensure that the first support member and the second support member can drive the arm to move when rotating, the arm is fixed to the first support member and the second support member through the binding straps.

[0018] A further technical solution of the present utility model is that the transmission mechanism includes a worm wheel connected to the rotating shaft, a worm in transmission connection with the worm wheel, and the worm is in shaft hole fit with the driving mechanism.

[0019] The driving mechanism is in shaft hole fit with the worm. The driving mechanism drives the worm to rotate, thereby transmitting to the worm wheel, and the worm wheel can drive the rotating shaft to rotate, realizing the movement of the first support member and the second support member.

[0020] A further technical solution of the present utility model is that a first limiting member is provided on the worm, and a limiting hole cooperating with the first limiting member is provided on the output end of the driving mechanism.

[0021] When the limiting member is inserted into the limiting hole, shaft hole fit is realized. When the driving mechanism is started, the worm wheel and the rotating shaft are driven to act by the rotation of the limiting member, completing the rotation of the first support member and the second support member. The cooperation between the limiting member and the limiting hole can quickly achieve docking without other connecting parts.

[0022] A further technical solution of the present utility model is that the first limiting member is in the shape of a handle.

[0023] After the transmission mechanism and the driving mechanism are disassembled, the first support member and the second support member can be rotated by manually rotating the limiting member, completing the rehabilitation training of the arm without motor drive; it is applicable to the situation where it is inconvenient to carry the driving mechanism.

[0024] A further technical solution of the present utility model is that a pointer is provided on the rotating shaft, and a scale disk is provided at the rotational connection between the first support member and the second support member.

[0025] When the rotating shaft rotates, the pointer rotates synchronously. When the pointer rotates, it corresponds to different rotation angles on the scale disk, so that the joint movement angle can be intuitively understood, thereby facilitating the control of the angle of each training and gradually carrying out the training.

[0026] A further technical solution of the present utility model is that a second limiting member for limiting the rotation of the first supporting member and the second supporting member is provided on the first supporting member or / and the second supporting member.

[0027] The limiting member can effectively avoid secondary injuries during the use of the training device.

[0028] The beneficial effects of the present utility model are as follows: When the user conducts training without the need to move, such as sitting or lying down, the upper arm and forearm of the arm are respectively attached to the first supporting member and the second supporting member, and the first supporting member and the second supporting member with the transmission mechanism are connected to the driving mechanism through the shaft hole fit. Then, the driving mechanism is started, so that the rotating shaft rotates to drive the first supporting member and the second supporting member to rotate, thereby completing the passive training of the joint; when the user needs to move, it is not convenient to carry the driving mechanism. For example, when going to the toilet, only need to lift the arm and the shaft is disengaged from the hole, and the driving mechanism can be detached, reducing the weight of the training device and facilitating the user's free movement, such as going out for a walk; in summary, the rehabilitation training device in the present utility model can meet the different needs of users, is not restricted by the rehabilitation training device, and the user can move freely; moreover, the driving mechanism can be placed on the support platform for use, reducing the load on the user.

[0042] Embodiment 1:

[0043] Figure 1-6 A joint rehabilitation training device is shown, including a first support member 1, a second support member 2, a transmission mechanism 4, and a driving mechanism 5. The first support member 1 is rotatably connected to the second support member 2 through a rotating shaft 3.

[0044] In this embodiment, the driving mechanism 5 includes a dual-axis motor 51 and a synchronous wheel 52. The output shafts at both ends of the dual-axis motor 51 are respectively connected to the synchronous wheel 52 through a synchronous belt. A driving shaft 53 is provided on the synchronous wheel 52. The driving shaft 53 is placed on both sides of the first support member 1 and the second support member 2 and is connected to the rotating shaft 3 through a transmission mechanism 4.

[0045] After the dual-axis motor is started, the output shafts at both ends rotate, driving the synchronous wheel to rotate through the synchronous belt, and the driving shaft on the synchronous wheel rotates; the driving shaft is connected to the rotating shaft through a transmission mechanism, thereby driving the rotating shaft to rotate, realizing the rotation of the first support member and the second support member, and achieving the effect of joint rehabilitation training; in the utility model, a motor is used to drive the rotating parts on both sides of the first support member and the second support member to rotate synchronously, and the first support member and the second support member are stable in movement and light in weight and small in size.

[0046] In this embodiment, the driving mechanism is placed in a housing, and the transmission mechanism passes through the housing and is connected to a driving shaft.

[0047] In this embodiment, the driving shaft is arranged perpendicular to the rotating shaft and is connected via a transmission mechanism.

[0048] In this embodiment, the driving shaft 53 is perpendicular to the rotating shaft 3 , and the driving shaft 53 is connected to the rotating shaft 3 via a transmission mechanism 4 .

[0049] The driving shaft is perpendicular to the rotating shaft and is connected through a transmission mechanism, which cooperates with the shaft hole of the driving shaft. When motor-driven training is required, the transmission mechanism only needs to be aligned with the driving shaft and lowered. When the user needs to move, or when the assistance of the driving mechanism is not required, the user only needs to lift his arm to complete the separation of the shaft and hole of the transmission mechanism and the driving mechanism. It is convenient and quick to use.

[0050] In this embodiment, a limiting hole is provided on the driving shaft, and a limiting pin which is gap-matched with the limiting hole is provided on the transmission mechanism.

[0051] In this embodiment, a receiving groove 6 is formed between the first supporting member 1 and the second supporting member 2 , and the rotational connection between the first supporting member 1 and the second supporting member 2 is located at two sides of the receiving groove 6 .

[0052] The rotating connection is located on both sides of the accommodating groove, and the accommodating groove between the first support member and the second support member is used to accommodate the joint when the joint moves, thereby avoiding friction between the joint and the hard structure and providing high comfort.

[0053] In this embodiment, a groove is provided at one end of the first support member, and a groove is also provided at one end of the second support member connected to the first support member. The groove on the first support member and the groove on the second support member constitute a receiving groove.

[0055] During use, the user fits the upper arm and the lower arm of the arm against the first support member and the second support member respectively. To ensure that the first support member and the second support member can drive the arm to move when rotating, the arm is fixed to the first support member and the second support member through the binding straps.

[0056] In this embodiment, the transmission mechanism 4 includes a worm wheel 41 connected to the rotating shaft 3 and a worm 42 in transmission connection with the worm wheel 41. The worm 42 is in shaft-hole fit with the driving mechanism 5.

[0057] The driving mechanism is in shaft-hole fit with the worm. The driving mechanism drives the worm to rotate, and thus transmits to the worm wheel. The worm wheel can drive the rotating shaft to rotate, realizing the movement of the first support member and the second support member.

[0058] In this embodiment, the worm wheel is sleeved on the rotating shaft. The transmission teeth on the worm wheel and the worm cooperate to achieve transmission. A limiting member for shaft-hole fit with the driving mechanism is provided on the worm.

[0059] In this embodiment, a first limiting member 43 is provided on the worm 42, and a limiting hole 54 for cooperating with the first limiting member 43 is provided on the output end of the driving mechanism 5.

The cooperation between the limiting member and the limiting hole can quickly achieve docking without other connecting parts.

[0061] In this embodiment, the limiting member is in the shape of a handle.

[0062] After the transmission mechanism and the driving mechanism are disassembled, the first support member and the second support member can be rotated by manually rotating the limiting member, completing the rehabilitation training of the arm without motor drive; this is applicable to the situation where it is inconvenient to carry the driving mechanism.

[0063] In this embodiment, the limiting member is S-shaped. In addition, it has no other shapes, such as non-circular structures like rectangles, triangles, rhombuses, etc. Besides being able to transmit power, it is also convenient for manual rotation.

[0064] In this embodiment, a pointer 31 is provided on the rotating shaft 3, and a scale disk is provided at the rotation connection of the first support member 1 and the second support member 2.

[0065] When the rotating shaft rotates, the pointer also rotates synchronously. When the pointer rotates, it corresponds to different rotation angles on the scale disk, so that the joint movement angle can be intuitively understood, thereby facilitating the control of the angle of each training and gradually carrying out the training.

[0067] In this embodiment, a second limiting member 7 for limiting the rotation of the first supporting member 1 and the second supporting member 2 is provided on the first supporting member 1 or / and the second supporting member 2.

[0068] The limiting member can effectively avoid secondary injuries during the use of the training device.

[0069] In this embodiment, the forearm is connected to the second supporting member, and the limiting member is disposed on the second supporting member. When the second supporting member rotates relative to the first supporting member, when the second supporting member rotates to the maximum angle, it will be limited by the limiting member, avoiding damage caused by excessive rotation of the joint. As another embodiment, the forearm is connected to the second supporting member, and the limiting member is disposed on the first supporting member for limiting.

[0070] The working principle of the present invention: When the user conducts training without moving, such as sitting or lying down, the upper arm and forearm of the arm are respectively attached to the first supporting member and the second supporting member, and the first supporting member and the second supporting member with the transmission mechanism are connected to the driving mechanism through the shaft-hole fit, and then the driving mechanism is started, so that the rotating shaft rotates to drive the first supporting member and the second supporting member to rotate, thereby completing the passive training of the joint; when the user needs to move, it is not convenient to carry the driving mechanism. For example, when going to the toilet, only need to lift the arm and pull the shaft out of the hole, and the driving mechanism can be disengaged, reducing the weight of the training device and facilitating the user's free movement, such as going out for a walk; In summary, the rehabilitation training device in the present invention can meet the different needs of users, is not restricted by the rehabilitation training device, and the user can move freely; moreover, the driving mechanism can be placed on the support platform for use, reducing the load on the user.
