Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable tilt angle lumbar disc negative pressure resonance therapy bed. Background Technology

[0002] Lumbar disc negative pressure resonance therapy is an effective treatment method specifically for lumbar disc problems. Through special negative pressure and resonance effects, it can effectively help patients relieve lower back pain and promote lumbar disc recovery. For example, the lumbar disc negative pressure resonance therapy machine with publication number CN201510427901.3 includes: a vibration therapy section, a traction therapy section, a manipulation therapy section, and a bed. During vibration therapy, it reduces the impact of vibration on the motor, increasing its service life. During manipulation therapy, it avoids the large force generated by repeated forward and reverse rotation of the drive, which could create inertia and cause changes in the traction amount.

[0003] However, while this lumbar disc negative pressure resonance therapy machine possesses multiple therapeutic functions, in actual use, the lack of an adjustable tilt angle mechanism on the bed makes it difficult to adjust the tilt angle according to the specific needs of patients of different body types and conditions. This results in poor coordination with the vibration therapy component, affecting both treatment effectiveness and patient comfort to some extent. Therefore, further improvements and optimizations are needed to better meet patient needs and enhance treatment outcomes. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adjustable tilt angle lumbar disc negative pressure resonance therapy bed, which solves the problem that existing lumbar disc negative pressure resonance therapy machines are difficult to adjust the tilt angle of the bed according to the specific needs of patients.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an adjustable tilt angle lumbar disc negative pressure resonance therapy bed, comprising a bed body, a three-dimensional adjustable sliding bracket fixedly connected to the middle of the rear end face of the bed body, a vibrator installed on the three-dimensional adjustable sliding bracket, a pair of vertical rods fixedly connected to the upper outer side of the bed body, and a first universal wheel connected to the bottom end of the vertical rods; an adjustment mechanism and a support mechanism are respectively installed inside and below the bed body. The adjustment mechanism includes a pair of first concave plates fixed to the inner wall of the upper right side of the bed.

[0007] Preferably, the support mechanism includes a second sliding plate that is slidably connected to a pair of sliding grooves at the bottom of the bed, and a sleeve is fixedly connected to the lower interior of the second sliding plate. A roller is fixedly connected to the outer side of the sleeve, and a bidirectional screw is threadedly connected to the inner side of the sleeve. A second drive assembly is installed in the middle of the bidirectional screw. The second sliding plate can limit the sleeve through the sliding grooves at the bottom of the bed, thereby ensuring that the bidirectional screw drives the sleeve to move.

[0008] Preferably, the second drive assembly includes a geared motor fixedly connected to the lower surface of the bed. The output shaft of the geared motor is fixedly connected to a first bevel gear, and the outer side of the first bevel gear is meshed with a second bevel gear fixedly connected to the outer wall of the bidirectional screw. The geared motor drives the second bevel gear to rotate through the first bevel gear, and the second bevel gear drives the bidirectional screw to rotate. The bidirectional screw, in conjunction with the second sliding plate, drives the sleeve to move, causing the sleeve to drive the roller to move, so that the roller extends outward from the bottom end of the bed.

[0009] Preferably, the first and second casters are self-locking casters; this ensures the stability of the bed when it is not moving.

[0010] Preferably, the roller is made of rubber; this way, when the roller contacts the ground, it can dampen the bed, making the bed more stable when adjusting the angle.

At the same time, the corresponding lumbar disc negative pressure resonance therapy structure can also adopt the corresponding structure in that patent. This application does not make any improvements to this.

[0021] In this embodiment, the first driving component includes a second concave plate 13 that is slidably connected to the outer wall of the bracket 11.

[0028] It is worth noting that all standard parts used in this invention can be purchased commercially, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The models of electrical structures and equipment involved can be selected according to the user's needs, as long as they meet the requirements of this application. Furthermore, the circuit connections adopt conventional connection methods in the prior art. The supporting electrical structures for control, current detection, position feedback, predicted voltage synchronization, and parameter adjustment of the electrical equipment are all existing technologies, such as PLC controllers and module structures, and therefore will not be described in detail here. All content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0029] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0030] Example: When this device is needed, the components can be assembled according to the diagram according to the assembly process, ensuring that the bolts are tightened and the welding is firm. Then, the circuit and control devices are connected. After checking that all interfaces are correct, the device is powered on for testing to ensure that the current detection, position feedback and other functions are normal. The control devices are then installed in appropriate positions. Before operation, all structures are cleaned. In the initial state, the upper surface of the bed 1 is horizontal. When it is necessary to adjust the overall height of the bed 1, the self-locking of the first universal wheel 7 can be released and the self-locking of the second universal wheel 7 can be locked. The geared motor 23 and the push rod motor 14 are started through the external controller. The geared motor 23 drives the second bevel gear 25 to rotate through the first bevel gear 24. The second bevel gear 25 drives the bidirectional screw 22 to rotate. The bidirectional screw 22, in conjunction with the second sliding plate 19, drives the sleeve 20 to move, causing the sleeve 20 to move the roller 21, which extends outward from the bottom of the bed 1. At the same time, the push rod motor 14 drives the second concave plate 13 to slide on the outer wall of the support 11. The second concave plate 13, in conjunction with the third concave plate 18, drives the cross rod 15 to move, and the cross rod 15 drives the slider 16 to slide on the first sliding plate 10. In this way, the first sliding plate 10, through the first connecting plate 9 and the first concave plate 8, can adjust the height of the right side of the bed 1. As the right side of the bed 1 rises, the roller 21 on the left side of the bed 1 will be in contact with the ground to provide support until the bed 1 is tilted to an appropriate angle, which makes it convenient for patients of different body types and conditions to use. During treatment, the vibrator 5 is mounted on the three-dimensional adjustable sliding bracket 4. The position of the vibrator 5 can be adjusted forward, backward, left, right, and up and down according to the specific position of the patient's waist. This allows the vibrator 5 to accurately act on the treatment area of ​​the patient's waist, so as to better exert the effect of negative pressure resonance therapy. The head fixation bracket 2 and the foot fixation bracket 3 are located on both sides of the top of the bed 1, respectively. They can fix the patient's head and feet to prevent unnecessary movement of the patient's body during treatment, which would affect the treatment effect. Furthermore, after the bed 1 has been used for a period of time, the various components can be disassembled, cleaned, and maintained by removing the bolts. Worn parts can be replaced in time to ensure that the device is always in good working condition.
