[0043] Embodiment 1

[0044] Embodiment 1 of the present utility model discloses a training device for leg rehabilitation (hereinafter referred to as "training device") to at least realize the bending and stretching training of the legs of patients with leg injuries who are unable to move independently.

[0045] As Figure 1 shown, it shows a schematic structural diagram of an exemplary training device disclosed in the embodiment of the present utility model. Generally, the training device may include a main body 10 and a leg training unit 20.

[0046] In this embodiment, the main body 10 is at least suitable for a patient to lie in a flat position. Among them, the main body 10 may have a structure substantially the same as that of a known hospital bed.

[0047] Furthermore, in combination with Figure 1 and Figure 2 shown, the main body 10 includes a frame 11, a first bearing part 12 and a second bearing part 13. Among them, the first bearing part 12 and the second bearing part 13 are arranged in sequence on the frame 11 along the X-axis direction. Among them, the X-axis direction mentioned in the embodiment of the present utility model can also be understood as the length direction of the main body 10, that is, the length direction of the patient when the patient is in a flat position. Among them, moving parts 14 such as universal wheels may be provided at the bottom of the frame 11 to improve the flexibility when moving the training device.

[0048] Among them, the first bearing part 12 and the second bearing part 13 together constitute a platform for the patient to lie on. Among them, the first bearing part 12 is suitable for bearing the legs of the patient, and the second bearing part 13 is suitable for bearing the upper body of the patient. That is to say, referring to Figure 6As shown, when the patient lies flat on the platform jointly formed by the first bearing part 12 and the second bearing part 13, the patient's legs can be supported by the first bearing part 12, and the patient's upper body can be supported by the second bearing part 13. Among them, a headrest part 15 is further provided on the side of the second bearing part 13 away from the first bearing part 12, so that when the patient lies down, the head can be rested on the headrest part 15, improving the comfort of the patient when lying down. Among them, a single leg of the patient carried on the first bearing part 12 may include the thigh, the calf, the foot, the knee joint connecting the thigh and the calf, and the ankle joint connecting the calf and the foot, etc. Of course, generally, the buttocks of the patient in the lying flat posture are also supported by the first bearing part 12.

[0049] In this embodiment, the leg training unit 20 is used to perform bending and stretching training on the legs of the patient carried on the first bearing part 12, specifically, the bending and stretching training between the thigh and the calf. Further, in this embodiment, a single leg training unit 20 is used to train a single leg of the patient. That is to say, in order to train the two legs of the patient, referring to Figure 1 As shown, two leg training units 20 arranged side by side in the Y-axis direction can be set simultaneously.

[0050] For a single leg training unit 20, combining Figure 1 As shown in the content, the leg training unit 20 may include a first movable part 21 and a second movable part 22 arranged in sequence on the first bearing part 12 along the X-axis direction. Among them, the first movable part 21 is adapted to be attached to the calf of the patient, specifically, the part of the calf near the ankle joint. And the first movable part 21 is also configured to be able to perform a reciprocating linear motion of approaching or departing from the second movable part 22 along the X-axis direction.

[0051] The second movable part 22 is located on the movement path of the first movable part 21 and is close to the second bearing part 13. Among them, the second movable part 22 is aligned with the knee joint of the patient. And the second movable part 22 is also configured to be able to perform a reciprocating linear motion of moving up or down along the Z-axis direction.

[0052] Further, the first movable part 21 and the second movable part 22 are also linked as follows: when the first movable part 21 performs a linear motion of approaching the second movable part 22 along the X-axis direction, the second movable part 22 performs a linear motion of moving up along the Z-axis direction; when the first movable part 21 performs a linear motion of departing from the second movable part 22 along the X-axis direction, the second movable part 22 performs a linear motion of moving down along the Z-axis direction.

[0053] Through the above settings, when it is necessary to perform bending and stretching training on the patient's legs, first let the patient lie flat on the main body 10. Among them, as Figure 6As shown, the upper body of the patient is supported by the second bearing part 13, and the patient's head is resting on the headrest part 15. The patient's buttocks and both legs are borne on the first bearing part 12.

[0054] Subsequently, the relevant parts of the patient's two legs are respectively attached to the relevant components of the two leg training units 20. Specifically, for a single leg of the patient and its corresponding leg training unit 20, the calf of the patient's single leg is attached to the first movable part 21, and the knee joint of the patient's single leg is borne on the second movable part 22.

[0055] After the above attachment between the legs and the leg training units 20 is completed, the bending and stretching training of the legs can be started. Specifically, for a single leg of the patient, in the initial state as shown in Figure 6 when the first movable part 21 is in a position away from the second movable part 22, at this time, the single leg of the patient is in a substantially horizontal extended state. After that, the first movable part 21 moves linearly along the X-axis direction towards the second movable part 22, so as to drive the calf attached to the first movable part 21 to move synchronously. During this process, the second movable part 22 moves linearly upwards along the Z-axis direction to lift the knee joint through the second movable part 22, so that the single leg of the patient changes from the Figure 6 extended state shown to the Figure 7 bent state shown. After the single leg of the patient is bent to an appropriate degree, the first movable part 21 moves linearly away from the second movable part 22 along the X-axis direction and resets, and the second movable part 22 moves linearly downwards along the Z-axis direction and resets, so that the single leg of the patient changes from the Figure 7 bent state shown to the Figure 6 extended state shown again. On this basis, by repeating the above steps, regular bending and stretching training of the single leg of the patient can be achieved.

[0056] It can be understood that in actual application, the two leg training units 20 can be used to alternately perform bending and stretching training on the two legs of the patient in turn to achieve better training effects.

[0057] In this embodiment, in order to achieve the linkage action between the first movable part 21 and the second movable part 22 described above, a single leg training unit 20 can further include a driving component 23.

[0058] As shown in Figure 3As shown, the driving component 23 may include a lead screw 231 and a driving motor 232. Among them, the lead screw 231 may be arranged below the first bearing portion 12, and the lead screw 231 extends along the movement direction of the first moving member 21, that is, the lead screw 231 extends along the X-axis direction. Moreover, the lead screw 231 is drivingly connected to the driving motor 232 so that the lead screw 231 can output a rotational motion about its own axis under the drive of the driving motor 232.

[0059] At this time, the first moving member 21 is drivingly engaged with the lead screw 231 to convert the rotational motion output by the lead screw 231 into a reciprocating linear motion of itself along the axial direction of the lead screw 231. Correspondingly, the second moving member 22 is also drivingly engaged with the lead screw 231 to convert the rotational motion output by the lead screw 231 into a reciprocating linear motion of itself along the Z-axis direction.

[0060] Furthermore, the driving cooperation between the first moving member 21 and the lead screw 231 can be achieved in the following manner.

[0061] Continue to refer to Figure 3 , a first connecting member 233 is threadedly connected to the lead screw 231. The first connecting member 233 can also freely slide along the axial direction of the lead screw 231, and the first connecting member 233 is also connected to the first moving member 21. Thus, when the lead screw 231 rotates, based on the principle of screw drive, the first connecting member 233 can be made to move linearly along the axial direction of the lead screw 231, and then the first moving member 21 is driven to move synchronously through the first connecting member 233. Among them, as Figure 2 shown, a first sliding groove 121 extending through the first bearing portion 12 and along the X-axis direction may be formed on the first bearing portion 12. The first connecting member 233 threadedly connected to the lead screw 231 can pass through the first sliding groove 121 and then be connected to the first moving member 21, and the first connecting member 233 is in sliding cooperation with the first sliding groove 121. In this way, the connection between the first connecting member 233 and the first moving member 21 can be realized, and the first connecting member 233 can freely slide along the axial direction of the lead screw 231.

[0062] Furthermore, the driving cooperation between the second moving member 22 and the lead screw 231 can be achieved in the following manner.

[0063] Continue to refer to Figure 3, a gear 234 is coaxially arranged on the lead screw 231 so that the gear 234 can rotate synchronously driven by the lead screw 231. At this time, a second connecting member 235 extending in the Z-axis direction is provided beside the gear 234, and the second connecting member 235 meshes with the gear 234. Among them, the second connecting member 235 can be a rack or other toothed members. And, the second connecting member 235 is also connected to the second moving member 22. Thus, when the lead screw 231 drives the gear 234 to rotate synchronously, the second connecting member 235 can make a linear motion in the Z-axis direction under the action of the gear 234, so as to drive the second moving member 22 to move synchronously through the second connecting member 235.

[0064] Based on the above settings, only by reasonably controlling the forward and reverse rotation of the lead screw 231, it can be achieved that when the first moving member 21 makes a linear motion close to the second moving member 22 along the X-axis direction, the second moving member 22 makes a linear motion upward along the Z-axis direction; when the first moving member 21 makes a linear motion away from the second moving member 22 along the X-axis direction, the second moving member 22 makes a linear motion downward along the Z-axis direction, thereby simplifying the structure of the leg training unit 20 as much as possible and reducing the use cost of the training device.

[0065] In this embodiment, for a single leg training unit 20, as Figure 4 shown, the first moving member 21 suitable for attaching to the calf of the leg may further include a horizontal support plate 211, a vertical positioning plate 212 and a first fastening belt 213. Among them, the horizontal support plate 211 is configured to be able to make a reciprocating linear motion close to or away from the second moving member 22 along the X-axis direction. For example, the aforementioned first connecting member 233 can be connected to the horizontal support plate 211 so that when the lead screw 231 rotates, the horizontal support plate 211 can be driven to move synchronously along the X-axis direction through the first connecting member 233. The vertical positioning plate 212 is connected to the horizontal support plate 211, and the vertical positioning plate 212 defines a vertical positioning surface 2121 facing the second moving member 22.

[0066] One end of the first fastening belt 213 is connected to one side of the vertical positioning plate 212, and the other end of the first fastening belt 213 bypasses the vertical positioning surface 2121 and is detachably connected to the other side of the vertical positioning plate 212. Among them, the first fastening belt 213 can be an elastic elastic band, and the first fastening belt 213 can be connected to the vertical positioning plate 212 by means of conventional detachable components such as Velcro.

[0067] Thus, when it is necessary to attach the first moving member 21 to the calf of a patient's single leg, refer to Figure 6As shown, the part of the patient's calf near the ankle can be placed on the horizontal support plate 211, and the patient's sole can be closely attached to the vertical positioning surface 2121 of the vertical positioning plate 212. Subsequently, the first fastening belt 213 can be passed around the patient's back and connected to the vertical positioning plate 212 to fix the patient's foot on the vertical positioning plate 212, thereby achieving the purpose of attaching the first movable member 21 to the patient's calf. When the first movable member 21 moves along the X-axis direction, it can reliably drive the patient's calf to move synchronously, and the patient's calf can be bent relative to the patient's thigh with the cooperation of the second movable member 22.

[0068] In this embodiment, for a single leg training unit 20, as Figure 5 shown, the second movable member 22 aligned with the patient's knee joint may include a horizontal bearing plate 221 and two second fastening belts 222. Among them, the horizontal bearing plate 221 is configured to be able to perform reciprocating linear motion upward or downward along the Z-axis. For example, the aforementioned second connecting member 235 can be connected to the horizontal bearing plate 221 so that when the lead screw 231 rotates, it can drive the horizontal bearing plate 221 to move synchronously along the Z-axis direction through the second connecting member 235.

[0069] Moreover, the horizontal bearing plate 221 further defines a horizontal bearing surface 2211 suitable for supporting the patient's knee joint from below. Among them, the horizontal bearing surface 2211 can be an arc surface to improve the comfort when the patient's knee joint is placed on the horizontal bearing surface 2211.

[0070] The two second fastening belts 222 are arranged in sequence along the X-axis direction. One end of each of the two second fastening belts 222 is connected to the same side of the horizontal bearing plate 221, and the other end of each of the two second fastening belts 222 passes around the horizontal bearing surface 2211 and is detachably connected to the other side of the horizontal bearing plate 221. Among them, the second fastening belt 222 can also be an elastic elastic band, and the second fastening belt 222 can also be connected to the horizontal bearing plate 221 by means of conventional detachable components such as Velcro.

[0071] Thus, when it is necessary to train the patient's leg, referring to Figure 6As shown, the knee joint of a patient's single leg can be placed on the horizontal bearing surface 2211 of the horizontal bearing plate 221. Subsequently, one of the second fastening straps 222 is passed around the part of the patient's calf near the knee joint and then connected to the horizontal bearing plate 221, and the other second fastening strap 222 is passed around the part of the patient's thigh near the knee joint and then connected to the horizontal bearing plate 221. At this time, the patient's knee joint is located between the two second fastening straps 222. In this way, when the horizontal bearing plate 221 moves upward in a straight line along the Z-axis direction driven by the second connecting member 235, the patient's knee joint can be lifted by the horizontal bearing plate 221. At the same time, due to the addition of the two second fastening straps 222, it can effectively prevent the knee joint of the patient from shifting when the horizontal bearing plate 221 lifts the knee joint of the patient, and since the knee joint is located between the two second fastening straps 222, it will not affect the normal bending of the knee joint.

[0072] Embodiment 2

[0073] On the basis of Embodiment 1, in order to further improve the flexibility of the training device during use, the structure of the main body 10 is further improved in this embodiment.

[0074] Combined with Figure 8 and Figure 9 As shown in the content, in this embodiment, one side of the second bearing part 13 close to the first bearing part 12 is pivotally connected to the frame body 11, so that the second bearing part 13 can pivot from the horizontal state shown in Figure 9 to the inclined state inclined relative to the horizontal plane shown in Figure 8 Thereby, it is beneficial to adjust the posture of the patient who needs to perform leg training according to needs, so as to improve the comfort of the patient during training. For example, when the second bearing part 13 pivots to the inclined state, the upper body of the patient can lean obliquely on the second bearing part 13, and the patient is in a reclined posture at this time.

[0075] On this basis, referring to Figure 8 As shown, the training device may further include two limiting members 30 and a limiting post 40. Among them, the two limiting members 30 are respectively arranged on both sides of the second bearing part 13 along the Y-axis direction, and a plurality of limiting holes 31 arranged in sequence along the pivoting path of the second bearing part 13 are provided on each limiting member 30, and the limiting post 40 is configured to pass through the corresponding limiting holes 31 on the two limiting members 30, so as to limit and support the second bearing part 13 pivoted to a predetermined pivoting position by the limiting post 40.

[0076] Specifically, when the second bearing part 13 is in the state as shown in Figure 9In the horizontal state shown, the second bearing part 13 can be directly borne on the frame body 11 so as to support the second bearing part 13 in the horizontal state through the frame body 11. Correspondingly, when the second bearing part 13 pivots relative to the first bearing part 12 to the inclined state as shown in Figure 8 After that, only by making the limit post 40 pass through the corresponding limit holes 31 on the two limit members 30, the second bearing part 13 can be limited and supported from the side of the second bearing part 13 facing away from the headrest part 15 through the limit post 40, so that the second bearing part 13 can be held at the current pivoting position. Correspondingly, when it is necessary to adjust the pivoting position of the second bearing part 13, first take out the limit post 40 from the corresponding limit holes 31 of the two limit members 30 so that the second bearing part 13 can pivot freely. After the second bearing part 13 pivots to the next pivoting position, only by making the limit post 40 pass through the corresponding limit holes 31 of the two limit members 30 again, the second bearing part 13 can be limited and supported again, and the operation is simple and convenient.

[0077] Furthermore, in order to avoid the existence of the two limit members 30 affecting the limited activity space near the body 10, the two limit members 30 can also be pivotally arranged on the frame body 11 so that each limit member 30 can be in the state as shown in Figure 8 The first position opposite to the side of the second bearing part 13 and the second position shown in Figure 9 Flipped at the second position on the side of the frame body 11.

[0078] In this way, when the second bearing part 13 is in the horizontal state, since the two limit members 30 are not needed, the two limit members 30 can be flipped to the second position on the side of the frame body 11, thereby avoiding the two limit members 30 occupying the limited activity space near the body 10. Correspondingly, when the second bearing part 13 is in the inclined state, only by flipping the two limit members 30 to the first position, the second bearing part 13 in the inclined state can be limited and supported in cooperation with the limit post 40.

[0079] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
