Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training, and more specifically, it relates to a PT rehabilitation training bed with a vibration device. Background Art

[0002] In the prior art, as an important rehabilitation medical device, a PT rehabilitation training bed with a vibration device mainly stimulates the leg muscles and nerves of patients through mechanical vibrations generated by vibration motors, so as to achieve the purpose of rehabilitation training. This training method can effectively promote blood circulation, enhance muscle strength, and improve nerve conduction function in theory, and has a positive rehabilitation effect on patients with lower limb dysfunction. However, at present, the designs of most rehabilitation training beds on the market have obvious deficiencies, and the vibration plate and the patient's legs adopt a direct rigid connection method.

[0003] This rigid connection design causes the mechanical vibration force generated by the vibration motor to be directly transmitted to the patient's legs without any buffering or shock-absorbing transition process. When the vibration intensity is relatively large, this direct force transmission will cause excessive stimulation to the patient's muscle tissues, joints and bones, easily causing discomfort, and even possibly leading to soft tissue injuries or aggravating the original diseases in severe cases. This design not only affects the rehabilitation training effect, but also increases the safety hazards during the treatment process and is not conducive to the patient's rehabilitation process.

Detailed implementation manners

[0017] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0018] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0019] In the present invention, unless otherwise stated, the orientations such as "upper, lower" are generally in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are generally the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of the respective components, but the above orientation terms are not used to limit the present invention.

[0020] Please refer to Figures 1 to 9, A PT rehabilitation training bed with a vibration device, comprising a bed body 11 and a receiving plate 12 mounted on the bed body 11; further comprising a receiving mechanism, the receiving mechanism includes a semi-circular sleeve 21 fixedly mounted on the receiving plate 12, a plurality of annular sleeves 22 are equidistantly mounted on the inner wall of the semi-circular sleeve 21, and a telescopic rod 23 is slidably connected in each annular sleeve 22 respectively. A follower spring 24 is mounted on the telescopic rod 23, and a fitting block 25 is mounted on the follower spring 24. A plurality of fitting blocks 25 are respectively attached to the legs of the patient. The receiving mechanism further includes a return spring 26 mounted at the lower ends of the plurality of annular sleeves 22, and the other end of the return spring 26 is connected to the telescopic rod 23. An outflow groove 27 is formed at the lower end of the annular sleeve 22.

[0021] When performing vibration rehabilitation training on the patient's legs, first, the patient lies on the bed body 11, and the casters under the bed body 11 have a locking function. Then, the two legs are respectively stuck on the semi-circular sleeve 21, and the thighs and calves are respectively stuck on the semi-circular sleeves 21 on the front and back sides. Please refer to Figure 4 , Since a plurality of annular sleeves 22 are respectively installed in each semi-circular sleeve 21, and a telescopic rod 23 is hermetically and slidably connected in each annular sleeve 22 respectively. When the legs extend into the semi-circular sleeve 21, a plurality of fitting blocks 25 are respectively attached to the outer walls of the legs. Since the space at the lower ends of the telescopic rod 23 and the annular sleeve 22 is filled with hydraulic oil, and the semi-circular sleeve 21, the adjusting pipe 31 and the energy storage tank 323 are also respectively filled with hydraulic oil, a corresponding supporting force will be provided to the telescopic rod 23. Then, through a plurality of fitting blocks 25 attached to the side walls of the legs, by starting two vibration motors, the receiving plate 12 and the semi-circular sleeve 21 can be driven to vibrate, and then the vibration is transmitted to the legs through the follower spring 24 and the fitting blocks 25 for corresponding rehabilitation training. When the vibration intensity is too large or a large supporting force is generated, the fitting blocks 25 supporting at the corresponding positions of the legs will generate a locally large pressure, and then the pressure is transmitted to the telescopic rod 23 through the follower spring 24. Since this instantaneous pressure hydraulic oil cannot quickly flow through the tiny through holes 36 into the other side, most of the pressure will still be applied to the one-way disc 37. At this time, a corresponding pressure will be applied to the hydraulic oil. Please refer to Figure 6 , And the pressure is transmitted into the adjusting pipe 31, and when the pressure exceeds the thrust of the push spring 311, the seal between the one-way disc 37 and the fitting disc 34 will be released, and then the hydraulic oil flows through the adjusting pipe 31 and passes through the transverse pipe 321 into the energy storage tank 323, and it will cause the piston disc 325 to move backward so that the hydraulic oil flows into the energy storage tank 323, thereby ensuring that the telescopic rod 23 at the corresponding position can move downward, so as to avoid damage to the legs caused by excessive pressure.

[0022] When the telescopic rod 23 expands and contracts downward, the hydraulic oil is squeezed into the adjusting pipe 31. Since the rotating sleeve 33 and the fitting plate are in a fitting position, and the diameter of the rotating sleeve 33 is the same as the diameter of the communication groove 35. Please refer toFigure 8 When the distance between the two is closer, the resistance for the hydraulic oil to flow through the rotating sleeve 33 into the communication groove 35 is greater. When the rotating sleeve 33 is very close to the fitting disc 34, the gap between them is very small at this time, so the inflow resistance is very large, thereby the force for the telescopic rod 23 to press down can be adjusted. By changing the size of the gap, the maximum supporting force of the leg can be adjusted, so it can be adjusted according to the training situation, thus completing the adjustment process.

[0023] When it is necessary to adjust the size of the gap between the rotating sleeve 33 and the fitting disc 34, first pull the pull rod 320 upward, then the inner ring 314 will move accordingly, and the inner ring 314 will abut against the pull sleeve 319, and then the pull sleeve 319 will move upward. Please refer to Figure 6 , since the insertion rod 315 is in limit sliding connection within the inner rod 312, and the vertical block 317 is in contact with the vertical groove 316, with the pulling of the pull rod 320, the inner rod 312 can be driven to be pulled outward accordingly. At this time, only a small position needs to be pulled outward, avoiding a large frictional force between the one-way disc 37 and the fitting disc 34. Then, rotating the pull rod 320 will drive the rotating rod 38 to rotate accordingly. Since the rotating rod 38 is in sliding connection within the rotating sleeve 33, the threaded sleeve 32 will be driven to rotate. Since the threaded sleeve 32 is in threaded connection with the adjusting pipe 31, it will move up and down along the adjusting pipe 31, thereby adjusting the opening and closing range of the gap, so the size of the inflow resistance can be adjusted, and thus the adjustment process is completed.

[0024] The adjusting mechanism includes two adjusting tubes 31 connected and installed on the side wall of the semi-circular sleeve 21. A threaded sleeve 32 is respectively threadedly connected in each adjusting tube 31. A rotating sleeve 33 is coaxially installed on the threaded sleeve 32. A fitting disc 34 is coaxially installed in the adjusting tube 31. A connecting groove 35 is formed on the fitting disc 34. The diameter of the rotating sleeve 33 is the same as that of the connecting groove 35. Four groups of through holes 36 are equidistantly formed on the fitting disc 34. The adjusting mechanism further includes a one-way disc 37 fittingly installed on the fitting disc 34. A rotating rod 38 is installed on the one-way disc 37. The rotating rod 38 is limited and slidably connected in the rotating sleeve 33. A receiving frame 39 is coaxially installed in the adjusting tube 31. A thrust bearing 310 is installed on the one-way disc 37. A push spring 311 is installed on the thrust bearing 310. The other end of the push spring 311 abuts against the side wall of the receiving frame 39. An inner rod 312 is coaxially installed on the one-way disc 37. The inner rod 312 is slidably connected in the receiving frame 39. A tail tube 313 is fixedly installed in the adjusting tube 31. An inner ring 314 is installed in the tail tube 313. An inserting rod 315 is coaxially installed on the inner ring 314. A vertical groove 316 is formed in the inner rod 312. A vertical block 317 is coaxially installed on the inserting rod 315. The vertical block 317 is slidably connected in the vertical groove 316. A tension spring 318 is sleeved on the tail tube 313. The other end of the tension spring 318 is connected to a tension sleeve 319. The tension sleeve 319 is slidably connected on the tail tube 313, and the tension sleeve 319 presses on the inner ring 314. A pull rod 320 is installed on the inner ring 314. Transverse tubes 321 are respectively installed on the two adjusting tubes 31. Two-way tubes 322 are respectively connected and installed on the two transverse tubes 321. Energy storage tanks 323 are respectively connected and installed on the two two-way tubes 322. An intermediate disc 324 is installed at the middle position of the energy storage tank 323. Piston discs 325 are respectively slidably connected at both ends of the energy storage tank 323. A plurality of springs 326 are respectively installed at both ends of the intermediate disc 324, and the plurality of springs 326 are respectively connected to the piston discs 325.

[0025] When the patient's leg is placed on the semi-circular sleeve 21, the telescopic rod 23 will be pressed downward. When the rehabilitation training process is completed, under the action of the return spring 26, the telescopic rod 23 will be continuously pushed upward to generate a certain return force. Then, under the action of the springs 326 at both ends, the hydraulic oil in the piston disc 325 will be pushed to flow into the annular sleeve 22 through the through holes 36. Therefore, the telescopic rod 23 can return, ensuring that it is in a reset state for the next use, and thus completing the usage process.

[0026] Among all the solutions mentioned above, for those involving the connection between two components, welding, the connection with bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those involving fixed connection mentioned above, welding is preferably considered.
