Description

Technical Field

[0001] The utility model relates to the technical field of treatment beds, in particular to a treatment bed with a musculoskeletal joint compression mechanism. Background Art

[0002] Chiropractic compression is a treatment method for orthopedic spine-related diseases. The operation is mainly performed on a chiropractic compression bed, in which the chiropractic compression device is the core key component. The chiropractic compression device usually uses a mechanical lifting mechanism to lift the bed board to meet the requirements of compression.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Figures 1 to 6 Shown is an embodiment of the utility model.

[0026] Embodiment 1:

[0027] like Figure 1-4 As shown, a treatment bed with a musculoskeletal joint compression mechanism comprises a base 1, on the upper side of which a head bed 33, a shoulder bed 34, a waist bed 4, and a leg bed 35 are sequentially mounted through a support frame 2, a waist bed frame 3 is arranged on the lower side of the waist bed 4 by the support frame 2, and the lower side of the waist bed 4 facing one end of the leg bed 35 is connected to the waist bed frame 3 by a rotating member 36, and a rotating rod 5 is arranged horizontally below the waist bed 4 on the waist bed frame 3, and a compression mechanism for driving one end of the waist bed 4 facing the shoulder bed 34 to be lifted around the rotating rod 5 is rotatably arranged on the rotating rod 5, and a pull plate 6 is arranged vertically on the lower side of the waist bed 4, and the lower end of the pull plate 6 is horizontally connected to a limit plate 7 below the rotating rod 5. When performing compression, the end of the waist bed 4 away from the rotating member 36 is driven to be lifted by the compression mechanism, and then the physician performs compression treatment. By setting the pull plate 6 and the limit plate 7, when the lumbar bed 4 is lifted, the pull plate 6 and the limit plate 7 will be driven to rise together. When the lumbar bed 4 is lifted to the limit, the limit plate 7 will fit the lower side of the rotating rod 5, thereby limiting the lumbar bed 4 from continuing to rise, playing a role of limit protection, and preventing the lumbar bed 4 from being lifted too high when a mechanical failure occurs. The rotating member 36 can be used as follows Figure 3 The connection plate plus the rotating shaft shown can lift the waist bed body 4 toward the shoulder bed body 34 around the rotating member 36 .

[0028] The pressing mechanism includes a damping plate 8, a damping rod 9, a rotating plate 10 and a push rod motor 11. The middle part of the damping plate 8 is rotatably connected to the rotating rod 5 through a rotating hole 12. One end of the damping plate 8 is connected to a horizontal rod 13. A top block 14 is provided on the lower side of the lumbar bed body 4. The lower side of the top block 14 is connected to the horizontal rod 13; the damping rod 9 is fixed to the lumbar bed frame 3, and one end of the damping rod 9 is connected to the side of the damping plate 8 away from the end of the horizontal rod 13; the rotating plate 10 is "L"-shaped, and the bending part of the rotating plate 10 is rotatably connected to the rotating rod 5 through a rotating sleeve 15, and one end of the rotating plate 10 is attached to the lower side of the horizontal rod 13; the base 1 of the push rod motor 11 is connected to the lumbar bed frame 3 through a first movable connecting piece, and the pushing end of the push rod motor 11 is connected to the end of the rotating plate 10 away from the horizontal rod 13 through a second movable connecting piece. During the compression treatment, the patient lies face down on the treatment bed, and the doctor or therapist starts the push rod motor 11, which performs repeated extension and retraction actions under the control of the controller, or the control button controls the extension and retraction respectively, wherein, Figure 7As shown, the push rod motor 11 can be controlled to automatically repeat the extension and retraction action by using a roller travel switch 37. The roller travel switch 37 is fixed on the lumbar bed frame 3, and the roller of the roller travel switch 37 is attached to the lower side of the lumbar bed body 4. In this way, when the lumbar bed body 4 is lifted, the transmission rod and roller of the roller travel switch 37 move with the lumbar bed body 4. When the maximum stroke is reached, the push rod motor 11 is controlled to retract. When the push rod motor 11 is extended, it will drive the rotating plate 10 to rotate around the rotating rod 5. The end of the rotating plate 10 placed on the lower side of the horizontal rod 13 will move upward, and then push the horizontal rod 13 upward. During the upward movement of the horizontal rod 13, the damping plate 8 will be driven to rotate around the rotating rod 5, and the top block 14 will be pushed upward, so that the lumbar bed 4 will be gradually lifted around the rotating member 36. When the push rod motor 11 is extended to a preset length, it will retract, and at this time, the rotating plate 10 will be driven to rotate around the rotating rod 5. Since the damping rod 9 and the damping plate 8 are connected by contact, the damping plate 8 will remain motionless, so that the lumbar bed 4 is kept in a lifted state by the horizontal rod 13 supporting the top block 14. When the push rod motor 11 is retracted to the shortest, the operator presses the patient's waist, and the force breaks through the damping force between the damping plate 8 and the damping rod 9, so that the lumbar bed board suddenly falls and fits on the lumbar bed frame 3 again, and then the push rod motor 11 is extended to start the next round of pressing operation. When the push rod motor 11 is extended, the push rod motor 11 will change its angle when extended because it will drive the rotating plate 10 to rotate around the rotating rod 5. In this way, the push rod motor 11 can be smoothly extended and shortened with the help of the first movable connecting member and the second movable connecting member. On the edge of the treatment bed, a foot pedal button 32 is placed for controlling the start and stop of the push rod motor 11. In this way, the doctor or therapist does not need to press the button by hand to start the push rod motor 11, but only needs to step on it, which is convenient to operate. In addition to setting a pressing mechanism on the lower side of the waist bed 4, the same pressing mechanism can be set on the lower side of the head bed 33 and the shoulder bed 34. The setting method and principle can be used in the same way, so that the musculoskeletal joints at different positions of the patient can be treated with pressing. The roller travel switch 37, the push rod motor 11 and the foot pedal button 32 can be linked and controlled by a controller, and the controller is provided with the most basic control chip and control program or control circuit that can control the operation of these components. In the prior art, there are a variety of control chips and control programs or control circuits that can achieve the above functions, which will not be repeated here.

[0029] A top ring 16 is sleeved on the horizontal rod 13, and the upper side of the top ring 16 is in contact with the lower side of the top block 14. By providing the top ring 16, it can better contact with the top block 14. The top ring 16 is installed at the position where the horizontal rod 13 fits the damping plate 8, and the upper side of the top ring 16 is placed on the upper side of the damping plate 8.

[0030] like Figure 6As shown, the damping rod 9 includes a sleeve 17 and an adjusting screw 18, one end of the sleeve 17 is connected to an adjusting nut 19, the middle part of the adjusting screw 18 is threadedly matched with the adjusting nut 19, one end of the adjusting screw 18 is connected to an adjusting spring 20 in the sleeve 17, and the other end is connected to a knob handle, one end of the adjusting spring 20 away from the adjusting screw 18 is top-contacted with a ball 21, a part of the ball 21 passes through the sleeve 17 and is top-contacted with the side of the damping plate 8; a plurality of grooves 22 matching the ball 21 are arranged on the side of the damping plate 8 facing the ball 21. Since the damping rod 9 is fixed on the lumbar bed frame 3, the damping rod 9 remains stationary, and the damping plate 8 will rotate around the rotating rod 5 driven by the horizontal rod 13. When the damping plate 8 rotates, the ball 21 fixed on the damping plate 8 by the damping rod 9 will roll on the damping plate 8. Since the damping plate 8 is provided with a groove 22, when the ball 21 rolls into the groove 22, the ball 21 will be pushed into the groove 22 with the help of the adjusting spring 20, so that a greater force is required to move the ball 21 out of the groove 22. When in use, the push rod motor 11 drives the damping plate 8 to rotate. When the push rod motor 11 is extended to the longest, the ball 21 just enters the groove 22. In this way, when the push rod motor 11 retracts, the cooperation of the ball 21 and the groove 22 can keep the lumbar bed body 4 in a lifted state. When the doctor performs compression, the impact force on the lumbar bed 4 causes the edge of the groove 22 to press the ball 21 into the sleeve 17, so that the damping plate 8 can rotate as the lumbar bed 4 is pressed down. By cooperating with the adjusting screw 18 and the adjusting nut 19, the length of the adjusting screw 18 extending into the sleeve 17 can be controlled, so that the length of the adjusting spring 20 can be controlled, so that the force generated by the adjusting spring 20 of different lengths against the ball 21 can be adjusted to adjust the force required to squeeze the ball 21 out of the groove 22, so that the doctor can adjust the different forces required to complete the compression operation when performing compression.

[0031] like Figure 5 As shown, the upper rotating sleeve of the rotating rod 5 is provided with a rotating sleeve 23, and the side wall of the rotating sleeve 23 is provided with a connecting block 24, and the end of the connecting block 24 away from the rotating sleeve 23 is connected to a toggle rod 25, one end of the toggle rod 25 is placed on the lower side of the damping plate 8, and the other end extends to the outside of the lumbar bed frame 3, and is connected with a curved handle 26. The push rod motor 11 needs to use a power supply to work, but when there is a power outage, or when there is no power supply, it is sometimes necessary to perform a pressing operation in this case. At this time, the doctor can hold the curved handle 26 to drive the toggle rod 25 to rotate around the rotating rod 5 through the rotating sleeve 23. When rotating, the toggle rod 25 will drive the damping plate 8 to rotate, thereby driving the horizontal rod 13 and the top ring 16 to regularly press the lumbar bed body 4 through the damping plate 8 to perform the pressing operation.

[0032] The lower side of the waist bed body 4 is provided with a cushion pad 27. By providing the cushion pad 27, when the waist bed body 4 falls, the cushion pad 27 and the waist bed frame 3 are in contact to play a cushioning role and a silencing role to avoid generating a loud sound. The cushion pad 27 can be made of a rubber block.

[0033] The first movable connecting member includes a first connecting plate 28 and a second connecting plate. One end of the first connecting plate 28 is connected to the lumbar bed frame 3, and a first movable hole is arranged on the side of the other end. One end of the second connecting plate is connected to the push rod motor 11, and a first rotating shaft 29 is arranged on the side of the other end. The first rotating shaft 29 is rotatably connected to the movable hole.

[0034] The second movable connecting member includes a third connecting piece 30, one end of which is connected to the end of the rotating plate 10 away from the horizontal rod 13, and the side of the other end is provided with a second movable hole, and the side of the pushing end of the push rod motor 11 is provided with a second rotating shaft 31, and the second rotating shaft 31 is rotatably connected to the second movable hole. When the push rod motor 11 is extended and shortened, the horizontal angle of the push rod motor 11 can be changed by means of the first rotating shaft 29 and the second rotating shaft 31, so that the push rod motor 11 can be smoothly extended and shortened.

[0035] Although the utility model is described herein with reference to a plurality of illustrative embodiments of the utility model, it should be understood that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the disclosure, drawings, and claims of the present application, various modifications and improvements may be made to the components and / or layout of the subject combination layout. In addition to the modifications and improvements made to the components and / or layout, other uses will also be apparent to those skilled in the art.
