Description

Technical Field

[0001] This invention relates to the field of medical assistive rehabilitation technology, specifically to a leg rehabilitation device. Background Technology

[0002] Traditional leg rehabilitation devices for slowing down arteriosclerosis in the lower extremities mostly use resistance training. However, this method requires patients to perform rehabilitation exercises, but the duration is short and there are certain training risks. Furthermore, this resistance training method does not meet the actual needs of patients who need to rest or elderly patients.

[0003] Therefore, we propose a leg rehabilitation device that can be used while sleeping or lying flat on a bed, which, through its height-adjustable design, enables sustainable rehabilitation training during long periods of sleep. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a leg rehabilitation device to extend the rehabilitation exercise time and reduce the training risk.

[0005] In a first aspect, the present invention provides a leg rehabilitation device, comprising: a support base, the support base including a lower base, a lifting assembly, and an upper support assembly; one end of the lifting assembly is disposed on the lower base, and the other end of the lifting assembly is disposed on the upper support assembly; the upper support assembly includes two opposing mounting frames; and a massage assembly disposed on the support base and located on the upper support assembly; the massage assembly includes a massage roller and a drive motor, the massage roller and the drive motor being respectively disposed on the mounting frames, wherein the drive motor drives the massage roller to rotate and is used to massage the patient's leg.

[0006] Furthermore, the lower base includes two opposing support frames and a connecting frame. The connecting frame has two members and is centrally hinged. The support frames have sliding grooves. Both ends of the connecting frame are slidably installed within the sliding grooves of the support frames. In practical applications, the purpose of this design is to ensure the proximity and separation of the two opposing support frames, thus achieving applicability to people with different leg widths.

[0007] Furthermore, the support base also includes extension frames, which are located on both sides of the lower base. The support frame also has two mounting holes at both ends; the extension frames have four holes, each rotatably mounted in one of the mounting holes. In practical application, the purpose of this design is to further maintain the stability of the device and prevent it from tipping over while working on the bed. In actual operation, the four extension frames increase the contact area between the device and the bed surface, thus maintaining stability.

[0008] Furthermore, the lifting assembly includes two lifting frames; the lifting frames are respectively disposed between the placement frame and the support frame; the lifting frame includes two centrally hinged support frames; one end of one support frame is hinged to the support frame and the other end is connected to the placement frame; one end of the other support frame is hinged to the placement frame and the other end is connected to the support frame.

[0009] In practical application, the purpose of this design is to achieve lifting and lowering, referencing the design of a scissor lift platform. The placement frame has an upper sliding groove, and the support frame has a lower sliding groove. One end of each of the two support hinges is slidably positioned in the upper and lower sliding grooves, facilitating lifting and lowering limits. Simultaneously, this design ensures that the patient's legs are higher than their body during sleep, maintaining good blood flow in the legs and effectively alleviating arteriosclerosis in the lower limbs. Furthermore, this leg-raising sleeping posture effectively references the rapid sleep method popular among Western marines and the elevated lying or foot-rest sleeping methods recorded in ancient Chinese texts. This method can improve sleep: leg raising and lowering the feet is a static exertion that can divert the brain's attention from thinking about problems, causing mild fatigue in the nervous system, thus inducing drowsiness and having a hypnotic effect. It also promotes blood circulation: this posture facilitates blood return, relieves calf muscle tension, and alleviates lower limb fatigue. It can also protect the spine: when doing this movement, the human spine can be kept in a horizontal position, which makes blood flow more smoothly and helps relieve spinal pressure.

[0010] Furthermore, the lifting assembly also includes a telescopic cylinder and a connecting frame; the connecting frame has two members, each located within one of the two support frames, wherein one end of the telescopic cylinder is connected to one of the connecting frames, and the other end is connected to the other connecting frame. In practical applications, the purpose of this design is to achieve lifting, and further realize a high-lying or foot-supported sleeping position; moreover, this method effectively ensures the horizontal stability of the lifting, avoiding unevenness. In actual operation, the telescopic cylinder is an electric cylinder.

[0011] Furthermore, the connecting frame includes a main pipe and a telescopic pipe, with one end of the telescopic pipe slidably installed inside the main pipe; wherein the main pipe is connected to one of the support frames, and the other end of the telescopic pipe is connected to another support frame. In practical application, the purpose of this design is to ensure the connection stability of the device during the widening process, and to prevent the stability of the two support frames from decreasing as they are pulled apart, thus effectively ensuring the stability of the device.

[0012] Furthermore, the massage assembly also includes multiple massage belts, each positioned between two of the placement frames. Each massage belt includes a massage abutment belt and a rotating motor. One end of the massage abutment belt is connected to the placement frame, and the other end is mounted on the rotating motor. When the patient places their legs on the massage abutment belt, the rotating motor rotates in both directions, driving the massage abutment belt to move up and down reciprocally. In practical application, the purpose of this design is to achieve up-and-down movement, avoiding the harm of insufficient blood flow caused by prolonged lying down with immobile lower limbs; thus effectively ensuring stability. In actual operation, the massage abutment belt is made of fabric, making it easy to replace and clean.

[0013] As can be seen from the above technical solution, the beneficial effects of the leg rehabilitation device provided by the present invention are as follows:

[0014] (1) In practical application, this design achieves the effect of accelerating blood return in the lower limbs by elevating the legs when the patient is lying in bed, that is, by designing the legs higher than the body; at the same time, it effectively avoids the need for resistance training and avoids the occurrence of harm during the training process; in this way, the device can be used by elderly patients, bedridden patients, and patients with leg disabilities; therefore, the device effectively increases the applicable population; in the actual design, the lifting component used can effectively adjust the height for different user groups, further increasing the applicable population.

[0015] (2) Moreover, the massage component used is driven by a hub motor, which is a small model. The drive motor bracket is installed inside the massage roller. In this way, the massage roller can be directly driven to rotate, which effectively realizes the overall compact structure and simplified design of the device, avoids the instability caused by complex design, and makes the overall operation reliable and stable.

Detailed Implementation

[0025] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0026] The basic implementation examples are as follows: Figures 1 to 6 As shown:

[0027] Example 1:

[0028] like Figure 1 - Figure 5 As shown, this embodiment provides a leg rehabilitation device that can increase rehabilitation exercise time and reduce training risks.

[0029] The present invention provides a leg rehabilitation device, comprising: a support base 1, the support base 1 including a lower base 11, a lifting assembly 12 and an upper support assembly 13; one end of the lifting assembly 12 is disposed on the lower base 11, and the other end of the lifting assembly 12 is disposed on the upper support assembly 13; the upper support assembly 13 includes two opposing placement frames 131; and a massage assembly 2, the massage assembly 2 being disposed on the support base 1 and located on the upper support assembly 13; the massage assembly 2 including a massage roller 21 and a drive motor 22, the massage roller 21 and the drive motor 22 being respectively disposed on the placement frames 131, wherein the drive motor 22 drives the massage roller 21 to rotate and is used to massage the patient's leg. In practical application, this design, by elevating the legs (higher than the body) when the patient is lying in bed, accelerates blood flow back to the lower limbs. It also effectively avoids the need for resistance training, preventing potential harm during the training process. This makes the device suitable for elderly patients, bedridden patients, and patients with leg disabilities, thus significantly expanding its applicability. The lifting component 12 in the actual design can effectively adjust the height for different user groups, further broadening its applicability. Furthermore, the massage component 2 uses a small hub motor 22, which is mounted inside the massage roller 21. This allows direct drive of the massage roller 21, effectively achieving a compact and simplified design, avoiding instability caused by complex designs, and ensuring reliable and stable operation.

[0030] In this embodiment, to facilitate the separation of the base and adjust the usage range and stability of the device, the lower base 11 includes two opposing support frames 111 and a connecting frame 112. The connecting frame 112 has two members and is centrally hinged. The support frame 111 has a sliding groove 1111. The two ends of the connecting frame 112 are slidably installed within the sliding grooves 1111 of the support frame 111. In practical applications, the purpose of this design is to ensure the proximity and separation of the two opposing support frames 111, thus achieving applicability to people with different leg widths and effectively serving a wide range of users.

[0031] To further improve the stability of the device on the bed surface, in this embodiment, the support base 1 further includes extension frames 113. The extension frames 113 are located on both sides of the lower base 11. The support frame 111 also has two mounting holes 1112 located at both ends of the support frame 111. The extension frames 113 have four locations, each rotatably mounted in one of the mounting holes 1112. In practical application, the purpose of this design is to further maintain the stability of the device and prevent it from tipping over while working on the bed. In actual operation, the four extension frames 113 increase the contact area between the device and the bed surface, thus maintaining stability.

[0032] To ensure stability during lifting, in this embodiment, the lifting assembly 12 includes two lifting frames 121. The lifting frames 121 are respectively located between the placement frame 131 and the support frame 111. Each lifting frame 121 includes two centrally hinged support hinges 1211. One end of one support hinge 1211 is hinged to the support frame 111, and the other end abuts against the placement frame 131. The other support hinge 1211 is hinged to the placement frame 131, and the other end abuts against the support frame 111. In practical applications, this design aims to achieve lifting, referencing the design of a scissor lift platform. The placement frame 131 has an upper sliding groove 1311, and the support frame 111 has a lower sliding groove 1113. One end of each of the two support hinges 1211 is slidably disposed in the upper sliding groove 1311 and the lower sliding groove 1113, thus facilitating lifting and limiting. This design ensures that the patient's legs are elevated above their torso during sleep, maintaining good blood flow and effectively alleviating arteriosclerosis in the lower limbs. Furthermore, this leg-raising sleeping position effectively references the rapid sleep techniques popular among Marines in Europe and America, as well as the elevated lying or foot-supported sleeping methods recorded in ancient Chinese texts. This method can improve sleep: leg raising is a static exertion that can divert the brain's attention from thinking about problems, causing mild fatigue in the nervous system, thus inducing drowsiness and having a hypnotic effect. It also promotes blood circulation: this posture facilitates blood return, relieves calf muscle tension, and alleviates lower limb fatigue. Moreover, it protects the spine: when performing this movement, the spine can be kept in a horizontal position, allowing for smoother blood flow and helping to relieve spinal pressure.

[0033] In this embodiment, the lifting assembly 12 further includes a telescopic cylinder 1212 and a connecting frame 1213. Two connecting frames 1213 are provided, each located within one of the two support frames 111. One end of the telescopic cylinder 1212 is connected to one of the connecting frames 1213, and the other end is connected to the other connecting frame 1213. In practical applications, the purpose of this design is to achieve lifting, further enabling high-lying or foot-supported sleeping positions. Moreover, this method effectively ensures the horizontal stability of the lifting, avoiding unevenness.

[0034] To ensure stability during use, in this embodiment, the connecting frame 1213 includes a main pipe 12131 and a telescopic pipe 12132, with one end of the telescopic pipe 12132 slidably installed inside the main pipe 12131. The main pipe 12131 is connected to one of the support frames 111, and the other end of the telescopic pipe 12132 is connected to another support frame 111. In practical application, the purpose of this design is to ensure the connection stability of the device during the widening process. Specifically, it aims to prevent a decrease in the stability of the two support frames 111 during the pulling-out process, thus effectively ensuring the stability of the device.

[0035] To further ensure the effectiveness of the massage, in this embodiment, the massage component 2 also includes a massage belt 23. The massage belt 23 has multiple locations, each positioned between two of the placement frames 131. The massage belt 23 includes a massage abutment belt 231 and a rotating motor 232. One end of the massage abutment belt 231 is connected to the placement frame 131, and the other end is mounted on the rotating motor 232. When the patient places their legs on the massage abutment belt 231, the rotating motor 232 can rotate in both directions, driving the massage abutment belt 231 to move up and down reciprocally. In practical application, the purpose of this design is to achieve up-and-down movement, avoiding the harm of insufficient blood flow caused by prolonged lying down with immobile lower limbs; thus effectively ensuring sleep stability.

[0036] Example 2:

[0037] like Figure 6As shown, the I-shaped placement component 300 provided in this embodiment is a further improvement on the placement frame 131 provided in another embodiment. Its cross-section is I-shaped. The I-shaped placement component 300 is provided with an upper mounting groove 301, a lower mounting groove 302, and a middle mounting cavity 303. This design can effectively facilitate the assembly of related components. In actual operation, the upper mounting groove 301 is used to install the massage roller 21 and the drive motor 22; the lower mounting groove 302 is used to install the support hinge 1211; and the middle mounting cavity 303 is used to install the massage belt 23. This effectively ensures the functional division of each component and avoids interference between the components during actual use, reducing mutual influence.

[0038] In summary, this leg rehabilitation device is not only reasonably designed but also easy to operate.
