Description

[0001] This application is a divisional application filed on April 23, 2024, with application number 202410487500.6 and titled "A Physiotherapy-Assisted Exercise Rehabilitation Hydrotherapy System". Technical Field

[0002] This invention belongs to the field of medical devices, specifically relating to an underwater treadmill in a sports rehabilitation hydrotherapy system. Background Technology

[0003] Hydrotherapy, as the name suggests, is "water therapy." It is an important treatment method widely used in rehabilitation. It utilizes the diverse properties of water to achieve therapeutic effects and has unique therapeutic effects on diseases such as osteoarthritis, stroke, and burns. It can also be used for early weight-bearing training after orthopedic surgery, gait correction training for hemiplegic patients, water limb function training for paraplegic patients, and progressive strengthening training of cardiopulmonary function. Therefore, it is favored by professional athletes and users with leg injuries or those who need to correct their walking posture.

[0004] For example, a combination of a hydrotherapy pool and an underwater treadmill can be used for leg rehabilitation training. The underwater treadmill can be adjusted up and down to create different levels of resistance, while the hydrotherapy pool creates a wave effect to increase the intensity and difficulty of the training. However, the underwater treadmill can generally only move up and down during hydrotherapy and cannot create an incline, which is very detrimental to leg rehabilitation. Furthermore, the training or rehabilitation provided cannot meet the needs of different users. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an improved water treadmill for a sports rehabilitation hydrotherapy system.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A water treadmill for a sports rehabilitation hydrotherapy system includes a circular running belt and a lifting mechanism for driving the circular running belt up and down. The circular running belt is mounted on a frame, and the lifting mechanism is a scissor lift installed at the bottom of the hydrotherapy pool. The frame is mounted on the support platform of the scissor lift. The water treadmill also includes an angle adjustment mechanism disposed between the support platform and the frame to drive the frame to rotate up and down around the horizontal direction, changing the angle between the circular running belt and the horizontal plane. The angle adjustment mechanism is connected to the dynamic monitoring unit of the sports rehabilitation hydrotherapy system, and the resistance formed by the water flow from the surf head of the sports rehabilitation hydrotherapy system changes synchronously when the angle changes. The angle adjustment mechanism includes support components located on opposite sides of the support platform, and positioning... A synchronous transmission component between two supporting components is provided, wherein, driven by the synchronous transmission component, the supporting components form different support angles to rotate the frame relative to the load-bearing platform; the supporting components include a support wheel and support arms respectively disposed on opposite sides of the support wheel, wherein the support arms are rotatably connected to the support wheel from one end and rotatably connected to the frame and the load-bearing platform respectively from the other end; the synchronous transmission component includes a synchronous shaft for connecting the two support wheel and a power unit for driving the synchronous shaft to rotate forward and backward, wherein, during the rotation of the support wheel, the position of the support arms changes to form angular support, and the three rotational support points formed by the two support arms on the same side are distributed in a triangle; the two support arms on the same side are of different lengths, and the lengths of the support arms on both sides are staggered vertically.

[0008] Preferably, the slope angle formed by the angle adjustment mechanism is inversely proportional to the resistance formed by the water flow generated by the surf head.

[0009] Furthermore, the slope angle created by the angle adjustment mechanism has a linear relationship with the resistance generated by the water flow ejected by the surf head. Specifically, the resistance decreases when moving uphill and increases when moving downhill. Here, the slope angle and resistance are correlated, and the combination of the two can reduce resistance during uphill movement or increase resistance during downhill movement, thereby increasing safety during uphill and downhill movements and also facilitating rehabilitation training in uphill and downhill conditions.

[0010] Preferably, the angle adjustment range formed by the angle adjustment mechanism is within 30°. Generally, around 20° is used because of space limitations, and larger angles pose uncontrollable risks. The small-angle design for uphill and downhill slopes in this application primarily meets the needs of different rehabilitation trainees.

[0011] According to another specific embodiment and preferred aspect of the invention, the lifting mechanism self-locks when the circular treadmill belt forms an angle; when the circular treadmill belt is in a horizontal state, the dynamic monitoring unit unlocks the lifting mechanism. Here, by locking and unlocking the lifting mechanism, the safety of the circular treadmill belt's lifting is ensured, avoiding lifting during uphill and downhill processes, which could lead to instability and a higher probability of falling (for rehabilitation patients, the risk of falling is uncontrollable).

[0012] According to another specific embodiment and preferred aspect of the invention, the three rotational support points remain in a triangular distribution regardless of the frame's angle. This ensures that the support points are readily available even when the machine is stopped, facilitating operation and providing stable support.

[0013] Each surf head is positioned side-by-side at one end of the circular treadmill belt, with the water outlet located above and to the side of the belt during rehabilitation training. The direction of the surge generated by each surf head is opposite to the direction of the flow generated by the circular treadmill belt.

[0014] According to another specific embodiment and preferred aspect of the invention, each surf head corresponds to a surfing station, and the circular treadmill belt is divided into single-person, double-person, or multi-person rehabilitation modes by the division of each surfing station, and is controlled by a dynamic monitoring unit. Therefore, single-person, double-person, or multi-person rehabilitation can be implemented.

[0015] In some implementations, each surf head has two water outlets distributed vertically, with the water jets from the two outlets either staggered vertically or with only one water jet exiting vertically. This arrangement creates varying surf resistance to meet the needs of different rehabilitation users.

[0016] Preferably, each water outlet has two branch pipes, one on the left and one on the right, so that selective flow can meet the needs of rehabilitation training under a certain height difference. At the same time, the water outlet and the water inlet are located at the same port, and the water inlet is distributed on the side of the water outlet. The advantage of this arrangement is that it facilitates the formation of strong surge resistance (the principle is similar to swimming. When you want to swim forward, you need to push the water backward. The water inlet in this application can play the role of pushing the water backward. Therefore, the impact force is large, that is, the resistance effect is good).

[0017] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0018] In existing hydrotherapy processes, underwater treadmills typically only move up and down, unable to create an incline, which is detrimental to leg rehabilitation. Furthermore, the resulting training or rehabilitation cannot meet the needs of different users. This invention cleverly solves these shortcomings by comprehensively designing the hydrotherapy system. With this system, the underwater treadmill's movement, combined with the adjustable walking resistance created by the surfing motion, allows for adjustment of the incline angle. This enables different users to perform underwater rehabilitation training in the same state, or for a single person to perform rehabilitation training at a suitable angle and resistance. Therefore, this invention not only allows for adjusting or setting corresponding training conditions (such as incline angle and resistance) according to the user's actual rehabilitation needs, providing optimal training for individuals or groups, and creating customized training plans, but also, under the monitoring of a dynamic monitoring unit, allows for adjustment of angle and resistance. Especially during inclines and declines, the resistance can be adaptively adjusted, increasing the safety of rehabilitation training (preventing falls) and allowing patients to gradually strengthen their rehabilitation training in an adaptive environment, thus improving rehabilitation outcomes.

[0041] like Figures 1 to 11 As shown, this embodiment is based on a physiotherapy-assisted exercise rehabilitation hydrotherapy system, which includes a hydrotherapy pool 1, an underwater treadmill 2, a dynamic monitoring unit 3, and a physiotherapy unit 4 installed on the hydrotherapy pool 1 and based on water as the transmission medium.

[0042] Specifically, the spa pool 1 includes a pool body 10 and a surfing mechanism 11 installed on the pool body; the underwater treadmill 2 includes a circular running belt 20 and a lifting mechanism 21 that drives the circular running belt 20 to move up and down; and the dynamic monitoring unit 3 includes a dynamic display 30 located at the end of the surfing mechanism 11 in the spa pool 1 and dynamic control and adjustment components.

[0043] In some specific embodiments, the surfing mechanism 11 includes two surf heads 110 and a water circulation component 111 that is respectively connected to the spa pool 1 and each surf head 110 to form surfing branches. The water circulation component 111 is wired and / or wirelessly connected to the dynamic monitoring unit 3, and the water circulation component 111 can adjust the water flow speed and pressure of each surfing branch so that the resistance formed by the water flow from the surf head 110 is adjustable.

[0044] Each surf head 110 is arranged side-by-side at one end of the circular running belt 20, and during rehabilitation training, the water outlet is located above and to the side of the circular running belt. This ensures that the direction of the resulting wave surge is opposite to the direction of its formation. Each surf head 110 corresponds to a surfing station, and the circular running belt 20 is divided into single-person, double-person, or multi-person rehabilitation modes based on these stations, controlled by a dynamic monitoring unit. Therefore, single-person, double-person, or multi-person rehabilitation can be implemented. In some specific embodiments, each surf head 110 has two water outlets a distributed vertically, wherein the water jets ejected from the two water outlets a are staggered vertically or only one water jet is ejected vertically. This arrangement creates different surfing resistances to meet the needs of different rehabilitation participants. Each water outlet a has two branch pipes a1, one on the left and one on the right, so that selective flow can meet the needs of rehabilitation training under a certain height difference. At the same time, the water outlet a and the water inlet b are located at the same port, and the water inlet b is distributed on the side of the water outlet a. The advantage of this setting is that it is easy to form a strong surge resistance (the principle is similar to swimming. When you want to swim forward, you need to push the water backward. The water inlet in this application can play the role of pushing the water backward. Therefore, the impact force is large, that is, the resistance effect is good).

[0045] Specifically, the water outlet a formed by the end face of the surf head 110 has a circular cross section, and parallel elongated holes are formed around the water outlet a, among which multiple elongated holes constitute the water inlet b.

[0046] The water circulation assembly 111 includes an inlet pipe b2, an outlet pipe b3, and a water pump b1. The outlet pipe b3 is connected to each water outlet, and a solenoid valve is formed along the connection path. The solenoid valve is connected to the dynamic monitoring unit 3. In short, solenoid valves are provided on the corresponding branch pipes to adjust the flow rate to meet the appropriate resistance requirements of rehabilitation training for different patients.

[0047] The circular running belt 20 is installed on the frame J. The lifting mechanism 21 is a scissor lift installed at the bottom of the spa pool 1. The frame J is installed on the support platform of the scissor lift. The underwater treadmill 2 also includes an angle adjustment mechanism 22 set between the support platform and the frame J to drive the frame J to rotate up and down around the horizontal direction to change the angle between the circular running belt 20 and the horizontal plane. The angle adjustment mechanism 22 is connected to the dynamic monitoring unit 3, and when the angle changes, the resistance formed by the water flow from the surf head changes synchronously.

[0048] The slope angle created by the angle adjustment mechanism 22 is inversely proportional to the resistance generated by the water flow from the surf head. In short, the slope angle created by the angle adjustment mechanism has a linear relationship with the resistance generated by the water flow from the surf head; resistance decreases when moving uphill and increases when moving downhill. Here, the slope angle and resistance are correlated, and their combination can reduce resistance during uphill movement or increase resistance during downhill movement, thereby increasing safety during both uphill and downhill sections and also facilitating rehabilitation training in uphill and downhill conditions.

[0049] In some specific embodiments, the angle adjustment range formed by the angle adjustment mechanism is within 30°. Generally, it is around 20°, because of space limitations, and the risk is uncontrollable if the angle is too large. The small angle design of the uphill and downhill slopes in this application mainly meets the needs of different rehabilitation trainees. The angle adjustment mechanism 22 includes support components 220 located on opposite sides of the bearing platform m, and a synchronous transmission component 221 located between the two support components 220. Under the drive of the synchronous transmission component 221, the support components 220 form different support angles to rotate the frame J relative to the bearing platform. Different angles are displayed under the support formed by the support components. In this example, the support component 220 includes a support wheel c and support arms d respectively arranged on opposite sides of the support wheel c. The support arms d are rotatably connected to the support wheel c from one end and rotatably connected to the frame J and the bearing platform from the other end. The synchronous transmission component 221 includes a synchronous shaft e connecting two support discs c and a power unit f driving the synchronous shaft e to rotate in both directions. During the rotation of the support discs c, the position of the support arms d changes to form angular support, and the three rotational support points formed by the two support arms on the same side are distributed in a triangle. Here, regardless of the frame's angle, the three rotational support points always maintain a triangular distribution, allowing for easy operation and stable support regardless of stopping or starting. In some specific embodiments, the two support arms d on the same side are of different lengths, and the lengths of the support arms on both sides are staggered vertically. This arrangement avoids motion interference on the left and right sides during forward and reverse rotation.

[0050] The physiotherapy unit 4 is connected to the dynamic monitoring unit 3. The physiotherapy unit 4 includes multiple ultrasound generators 40 installed on the hydrotherapy pool 1, all of which are connected in parallel with the dynamic monitoring unit (they can be used individually or multiple generators can be used simultaneously). Ultrasound therapy is used to stimulate the patient, thereby shortening the rehabilitation training cycle and facilitating the completion of rehabilitation training with higher quality.

[0051] Furthermore, the lifting mechanism self-locks when the circular treadmill belt 20 forms an angle; the angle adjustment mechanism 22 unlocks the lifting mechanism when the circular treadmill belt is in a horizontal state, thanks to the dynamic monitoring unit. Here, the locking and unlocking of the lifting mechanism ensures the safety of the circular treadmill belt's lifting and lowering, preventing instability and a higher probability of falls during uphill and downhill processes (for rehabilitation patients, the risk of a fall is uncontrollable).

[0052] In summary, this hydrotherapy system utilizes the adjustable vertical movement of the underwater treadmill combined with the walking resistance created by surfing. The incline angle can also be adjusted, allowing different users to perform underwater rehabilitation training in the same state, or for a single person to perform rehabilitation training at a suitable angle and resistance. Simultaneously, the physiotherapy unit stimulates the user's rehabilitation areas to achieve therapeutic effects. Therefore, this invention not only allows for the adjustment or setting of corresponding training conditions (such as incline angle and resistance) according to the user's actual rehabilitation needs for optimal training for individuals or groups, and the creation of training programs tailored to each individual, but also combines physiotherapy and hydrotherapy to effectively stimulate reflex points at the injured area, accelerating rehabilitation efficiency, and enabling dynamic monitoring. Under the unit's monitoring, the angle and resistance can be adjusted, especially when going uphill or downhill. The resistance can be adaptively adjusted, which not only increases the safety of rehabilitation training (avoiding falls) but also allows patients to gradually strengthen their rehabilitation training in an adaptive environment, improving the rehabilitation effect. Thirdly, each surf head is distributed side by side at one end of the circular running belt, and during rehabilitation training, the water outlet is located on the upper side of the circular running belt. This ensures that the direction of the surge is opposite to the direction of formation. The circular running belt is divided into single, double, or multiple rehabilitation modes by the surfing stations, and is controlled by the dynamic monitoring unit. Therefore, single, double, or multiple rehabilitation can be implemented. At the same time, the water jets from the two water outlets are staggered vertically or only one water jet is jetted vertically. This layout... To create varying surf resistance and meet the needs of different rehabilitation patients, each water outlet has two branch pipes, one on the left and one on the right. This allows for selective flow to accommodate rehabilitation training at different elevation differences. Furthermore, the water outlet and inlet are located at the same port, with the inlet distributed to the side of the outlet. This arrangement facilitates the generation of strong surge resistance (similar to swimming; to move forward, the water needs to be pushed backward, and the inlet in this application effectively pushes the water backward, resulting in a strong impact and thus good resistance). Fourthly, the slope angle created by the angle adjustment mechanism is linearly related to the resistance generated by the water flow from the surf head. Specifically, when moving forward uphill, the resistance... The resistance decreases as the machine moves downhill. Therefore, the slope angle and resistance are correlated, and the combination of the two can reduce resistance during uphill or increase resistance during downhill, thereby increasing safety during uphill and downhill, and also facilitating rehabilitation training in uphill and downhill conditions. Fifthly, during the rotation of the support wheel, the position of the support arm changes to form angular support, and the three rotation support points formed by the two support arms on the same side are distributed in a triangle. Thus, no matter what angle the frame is at, the three rotation support points always maintain a triangular distribution. This allows for easy operation and stable support, and the two support arms on the same side are of different lengths, and the lengths of the support arms on both sides are staggered vertically. This design avoids movement interference on the left and right sides during forward and reverse rotation.The sixth aspect involves using ultrasound therapy to stimulate the patient, shortening the rehabilitation training cycle and facilitating high-quality completion of rehabilitation training. Simultaneously, the locking and unlocking mechanism of the lifting system ensures the safety of the circular treadmill belt's movement, preventing instability and falls during uphill and downhill sections (a risk that is uncontrollable for the patient once they fall).

[0053] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be included within the scope of protection of the invention.
