Description

Technical Field

[0001] The present invention relates to the technical field of training devices, and in particular to an aerobic training device for cardiopulmonary rehabilitation. Background Art

[0002] Aerobic training in cardiopulmonary rehabilitation is of great significance for improving patients' cardiopulmonary function and promoting physical recovery. With the development of rehabilitation medicine, various special equipment has been designed to meet the rehabilitation needs of different patients; underwater treadmill, as a special aerobic training device, can effectively reduce the burden on joints while providing a low-impact environment. It is particularly suitable for injured athletes and people who need special care to conduct rehabilitation training of the cardiopulmonary and musculoskeletal systems.

[0003] Traditional underwater treadmills usually adopt a box structure with an opening on the top and closed on all sides. Users can enter the box through the top opening. However, this design has obvious inconveniences: whether entering the box before or after filling the water, the user needs to step over the edge of the box, which is a challenge for people with limited mobility.

[0004] In order to solve this problem, patent number CN114392523B discloses an underwater treadmill. By setting an openable door on the side of the underwater treadmill box, the user can enter and exit directly through the door, avoiding the action of crossing the box; however, although this method improves the convenience of use to a certain extent, it still faces some technical difficulties in actual application. For example, the sealing performance between the door and the box is difficult to ensure, which easily leads to water leakage at the interface; in addition, the fixed height box design cannot adapt to the needs of users of different heights. If it is too high, it will block the line of sight and cause a sense of oppression. If it is too low, it may lead to insufficient water volume, affecting the rehabilitation effect.

DETAILED DESCRIPTION

[0032] The present invention will be described in detail below with reference to the accompanying drawings.

[0033] Example: An aerobic training device for cardiopulmonary rehabilitation, see Figures 1-8As shown, it includes a support base 1; it also includes a connecting frame 2, a treadmill, a driving mechanism, a guide rail 5, a skateboard 6, a square frame 7, an electric push rod 8, a square rubber bellows 9, a handrail 10, a hollow frame 1001, a turbine 1002, a filter 1003, a gear 1004, a first motor 1005 and a first magnetic coupler 1006; a connecting frame 2 is installed on the top left side of the support base 1; a treadmill is provided on the top left side of the support base 1, and the treadmill is located inside the connecting frame 2. The treadmill includes a roller 301 and a running belt 302. Two rollers 301 are rotatably provided on the top left side of the support base 1. The two rollers 301 are distributed left and right, and a running belt 302 is wound between the two rollers 301; a driving mechanism is provided on the support base 1, and the driving mechanism The structure is used to drive the roller 301 on the left to rotate; the six guide rails 5 are symmetrically installed on the side of the connecting frame 2; two slide plates 6 are slidably set between the three guide rails 5 on the left, and two slide plates 6 are also slidably set between the three guide rails 5 on the right; a square frame 7 is connected between the tops of the four slide plates 6; an electric push rod 8 is connected to the guide rails 5 in the middle on the left and right sides, and the telescopic rods of the two electric push rods 8 are connected to the square frame 7, and the electric push rod 8 is used to drive the square frame 7 to rise and fall; a square rubber bellows 9 is connected to the top of the connecting frame 2, and the top of the square rubber bellows 9 is connected to the bottom of the square frame 7; a handrail 10 is installed on the left side of the square frame 7; a hollow frame 1001 is also installed on the left side of the square frame 7, and the hollow frame 1001 is located at the handrail Directly below the rod 10; five turbines 1002 are arranged at intervals on the right side of the hollow frame 1001, and the turbines 1002 are used to drive the water flow to exert water resistance on the user during training by utilizing the water flow movement, and by adjusting the rotation force of the turbines 1002, the water resistance encountered by the user during training can be adjusted; a filter screen 1003 is connected to the right side of the hollow frame 1001, and the filter screen 1003 is used to prevent the trainee's limbs from extending into the hollow frame 1001; ten gears 1004 are arranged at intervals on the left side of the hollow frame 1001, and two adjacent gears 1004 are meshed, and the five turbines 1002 are respectively connected to the five adjacent gears 1004; the upper left sides of the two slides 6 on the left are connected to the first motor 1005; the first motor A first magnetic coupler 1006 is installed between the output shaft of the motor 1005 and the adjacent gear 1004. The first magnetic coupler 1006 is mainly composed of two circular magnets, which are respectively connected to the output shaft of the first motor 1005 and the adjacent gear 1004. A square rubber bellows 9 is placed between the two circular magnets. When the output shaft of the first motor 1005 rotates, the output shaft of the first motor 1005 will drive the circular magnet on the gear 1004 to rotate, so that the gear 1004 drives the turbine 1002 to rotate. Using the first magnetic coupler 1006 as the transmission method can make the first motor 1005 be located on the outside of the square rubber bellows 9, thereby preventing the first motor 1005 from being immersed in liquid.

[0034] See Figure 2 and Figure 3 As shown, the driving mechanism includes a second motor 401 and a second magnetic coupler 402; the second motor 401 is installed on the left front side of the support base 1; a second magnetic coupler 402 is installed between the output shaft of the second motor 401 and the front end of the left roller 301, and the second magnetic coupler 402 is mainly composed of two circular magnets, which are respectively connected to the output shaft of the second motor 401 and the front end of the left roller 301, and the two circular magnets are respectively located on the inner and outer sides of the connecting frame 2. When the output shaft of the second motor 401 rotates, the output shaft of the second motor 401 will drive the circular magnet on the outside of the connecting frame 2 to rotate, so that the circular magnet drives the circular magnet on the inside of the connecting frame 2 and the left roller 301 to rotate through magnetic force. The second magnetic coupler 402 is used as a transmission method to ensure the integrity of the connecting frame 2, and there is no need to make a through hole in the connecting frame 2, thereby preventing the connecting frame 2 from leaking.

[0035] In the initial state, the telescopic rod of the electric push rod 8 is in a retracted state, so that the position of the square frame 7 is lowered, so that the user can directly step over the square frame 7 and enter the inner side of the square rubber bellows 9; When in use, first let the user directly step over the square frame 7 and enter the inner side of the square rubber bellows 9, so that the user can stand on the treadmill belt 302, and then drive the square frame 7 to move upward through the electric push rod 8, so that the square frame 7 drives the slide plate 6 and the handrail 10 to move upward, and the square frame 7 pulls the square rubber bellows 9 to expand until the top surface of the square frame 7 exceeds the user's specified part, so that the square frame 7 is in a suitable position according to the user's height, and then let the user hold the handrail 10 to stabilize the body, and then pour warm water of appropriate temperature into the square rubber bellows 9 and the connecting frame 2 until the warm water submerges the user's specified part, and then use the second motor 401 to drive the left roller 301 to rotate through the second magnetic coupler 402, thereby driving the treadmill belt 302 to perform elliptical motion, so that the user can perform running training on the treadmill belt 302 and perform aerobic training in the water, so as to help the user perform cardiopulmonary rehabilitation. During aerobic training, the user uses the first motor 1005 to drive the gear 1004 to rotate through the first magnetic coupler 1006, so that the gear 1004 can drive the turbine 1002 to rotate, so that the turbine 1002 generates a directional water flow toward the user. This directional water flow can not only increase the overall resistance encountered by the user during training, but also simulate different flow rate conditions, providing the user with a more diverse and high-intensity training experience. The force of the first motor 1005 driving the gear 1004 to rotate can also adjust the water resistance encountered by the user during training. When the user completes aerobic training, the warm water in the square rubber bellows 9 and the connecting frame 2 is pumped out, and then the electric push rod 8 drives the square frame 7 to move downward and reset, so that the square frame 7 drives the slide plate 6 and the handrail 10 to move downward and reset, and the square frame 7 presses the square rubber bellows 9 to contract and reset, and finally the user steps over the square frame 7 from the inside of the square rubber bellows 9 to leave.

[0036] See Figure 9 As shown, a step 11 is also included; a step 11 is also provided on the left front side of the support base 1, and the step 11 is used to guide the human body into the connecting frame 2.

[0037] By providing the step 11 , it is convenient for the user to step over the square frame 7 via the step 11 and enter the inner side of the square rubber bellows 9 , thereby guiding the user to enter the connection frame 2 .

[0038] See Figure 9 and Figure 10As shown, it also includes a heating mechanism, which includes a fixed frame 12, a heater 13, a first water pump 14, a water pipe 15, a return pipe 16 and a one-way valve 17; a fixed frame 12 is installed on the top right side of the support base 1; four heaters 13 are arranged at intervals on the top right side of the support base 1, and the four heaters 13 are all located on the inner side of the fixed frame 12; a first water pump 14 is provided on the top of the support base 1, and the first water pump 14 is located between the connecting frame 2 and the fixed frame 12, and the water inlet of the first water pump 14 is connected to the connecting frame 2; a water pipe 15 is connected between the water inlet ends of the heaters 13, and the water pipe 15 passes through the fixed frame 12 and is connected with the water outlet of the first water pump 14; a return pipe 16 is connected between the water outlet ends of the heaters 13, and the return pipe 16 passes through the fixed frame 12 and is connected with the connecting frame 2; a one-way valve 17 is provided on the return pipe 16, and the one-way valve 17 can only discharge the water in the return pipe 16 into the connecting frame 2.

[0039] See Figure 9 and Figure 10 As shown, a detection mechanism is also included, which includes a controller 18 and a temperature detector 19; the controller 18 and the temperature detector 19 are installed on the front side of the connection frame 2, and the controller 18 is located below the temperature detector 19. The temperature detector 19 is used to detect the temperature of the liquid in the connection frame 2, and the temperature detector 19, the first water pump 14 and the heater 13 are all electrically connected to the controller 18.

[0040] By providing a heating mechanism and a detection mechanism, when the user performs aerobic training in water, the temperature of the warm water in the connecting frame 2 can be detected by the temperature detector 19. When the temperature detector 19 detects that the temperature of the warm water in the connecting frame 2 is lower than a preset value, the temperature detector 19 will send a signal. After receiving the signal, the controller 18 will control the first water pump 14 and the heater 13 to start, so that the first water pump 14 draws the warm water in the connecting frame 2 into the heater 13 through the water pipe 15, so that the heater 13 heats the warm water. The heated warm water is then returned to the connecting frame 2 by the return pipe 16 and the one-way valve 17. In this way, the warm water in the connecting frame 2 can be automatically heated. When the temperature detector 19 detects that the temperature of the warm water in the connecting frame 2 is higher than a preset value, the temperature detector 19 will send a signal. After receiving the signal, the controller 18 will control the first water pump 14 and the heater 13 to shut down. In this way, it can be ensured that the warm water in the connecting frame 2 is within a certain temperature range for a long time, preventing the warm water in the connecting frame 2 from being affected by being too cold or too hot.

[0041] See Figure 11 and Figure 12As shown, it also includes a water storage mechanism, which includes an intelligent heating water tank 20, a drain valve 21, a dosing pipe 22, a second water pump 23, a mounting frame 24, a frame plate 25, a first connecting pipe 26 and a second connecting pipe 27; an intelligent heating water tank 20 is installed on the top of the fixed frame 12, and the intelligent heating water tank 20 has a built-in heating function for heating the water therein; a drain valve 21 is provided on the lower right side of the intelligent heating water tank 20, and the drain valve 21 is used to discharge the water in the intelligent heating water tank 20; the top of the intelligent heating water tank 20 is connected to the dosing pipe 22. The dosing pipe 22 is arc-shaped, which can prevent dust falling from top to bottom from entering the intelligent heating water tank 20 through the dosing pipe 22; a second water pump 23 is installed on the right front side of the connecting frame 2, and the water inlet of the second water pump 23 is connected to the connecting frame 2; a mounting frame 24 is installed on the front side of the fixed frame 12; a frame plate 25 is detachably installed on the front side of the mounting frame 24; both ends of the first connecting pipe 26 are respectively connected to the water outlet of the second water pump 23 and the mounting frame 24; both ends of the second connecting pipe 27 are respectively connected to the mounting frame 24 and the intelligent heating water tank 20.

[0044] By setting up the water storage mechanism, the filter 28 and the reflux mechanism, when the user completes aerobic training, the second water pump 23 can be used to pump the warm water in the connecting frame 2 into the installation frame 24 through the first connecting pipe 26, and then the filter 28 will filter the warm water in the installation frame 24. Then the filtered warm water will be sent to the intelligent heating water tank 20 through the second connecting pipe 27 for storage, until all the warm water in the connecting frame 2 is pumped into the intelligent heating water tank 20 for storage, and then the frame plate 25 will be removed, so that the frame plate 25 will take out the filter 28, and then the filter 28 will be cleaned, and then the frame plate 25 will be installed back to its original position, so that the frame plate 25 will drive the filter 28 Return to the original place, and then decide whether to reuse the warm water according to the water quality of the warm water: if the warm water needs to be reused, add the chemical disinfectant into the intelligent heating water tank 20 through the dosing pipe 22 to disinfect the warm water in the intelligent heating water tank 20. Then, when it is used next time, the water in the intelligent heating water tank 20 can be heated to a specified temperature through the intelligent heating water tank 20, and then the third water pump 29 is used to pump the warm water in the intelligent heating water tank 20 into the connecting frame 2 through the third connecting pipe 30 for use. In this way, water resources can be reused, thereby saving water resources; if the warm water does not need to be reused, the warm water in the intelligent heating water tank 20 is discharged through the drain valve 21.
