Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0032] like Figure 1 and Figure 5As shown in the figure, this embodiment provides a multifunctional rehabilitation nursing device for rehabilitation medicine, including a bed frame 1, a headboard 2 fixedly connected to one end of the bed frame 1, a footboard 3 fixedly connected to the other end of the bed frame 1, and the bed frame 1 includes an exercise mechanism 8 and an adjustment mechanism 9.

[0033] A fixed plate 4 is fixedly connected to the center of the bed frame 1. An upper body movable plate 5 is hinged to one end of the fixed plate 4. An electric push rod 10 is provided at the bottom of the upper body movable plate 5. A thigh movable plate 6 is hinged to the other end of the fixed plate 4. A lower leg movable plate 7 is hinged to one end of the thigh movable plate 6.

[0034] The bed frame 1 has symmetrical moving grooves 13 on the inner side near the footboard 3. The bottom wall of the moving groove 13 has a lifting groove 14. The inner wall of the lifting groove 14 is slidably connected to a one-way toothed plate 94. The bottom end of the one-way toothed plate 94 is fixedly connected to several connecting rods 92. The top of the several connecting rods 92 is fitted with a third spring 93. The bottom ends of the several connecting rods 92 pass through the bottom wall of the lifting groove 14 and are fixedly connected to the same pressure plate 91.

[0035] Both sides of the lower leg movable plate 7 are provided with blocks 73, which are slidably connected to the inner wall of the moving groove 13. The bottom of the block 73 is provided with a corrugated groove, which is engaged with the top of the one-way toothed plate 94.

[0036] Specifically, by extending and retracting the electric push rod 10, the upper body movable plate 5 is pushed to rotate around the hinge point with the fixed plate 4, thereby adjusting the angle of the patient's upper body to meet the patient's different lying needs, such as semi-reclining, sitting up, etc., so that the patient can rest, eat, read and other activities.

[0037] When the lower limb position needs to be adjusted, push the lower leg movable plate 7, which causes the block 73 to slide within the moving groove 13. During the movement, the block 73 presses down on the one-way toothed plate 94 through the convex part of the corrugated groove at the bottom, which overcomes the elastic force of the third spring 93, and thus moves above the tooth groove of the one-way toothed plate 94. When the block 73 moves to the appropriate position, the third spring 93 causes the one-way tooth at the top of the one-way toothed plate 94 to re-engage into the concave part of the corrugated groove at the bottom of the block 73, thus fixing it. This allows the lower leg movable plate 7 to be adjusted in angle within a certain range, achieving the purpose of setting the thigh movable plate 6 and the lower leg movable plate 7 at an acute angle. This precisely lifts the back of the knee of the rehabilitation patient, allowing both legs to bend, promoting the recovery of knee joint function, and helping to improve the rehabilitation effect. At the same time, it provides the rehabilitation patient with a leg posture that is closer to a natural state, increasing the patient's comfort and relaxation on the rehabilitation bed.

[0038] When it is necessary to restore the thigh movable plate 6 and the calf movable plate 7 to a flat state, press down on the pressure plate 91. The pressure plate 91 drives the one-way toothed plate 94 through the connecting rod 92 to overcome the elastic force of the third spring 93 and slide down, releasing the restriction on the calf movable plate 7, so that the calf movable plate 7 moves towards the bed end plate 3, thereby achieving the purpose of restoring the thigh movable plate 6 and the calf movable plate 7 to a flat state.

[0039] In a further embodiment, a sliding groove 71 is symmetrically provided at one end of the lower leg movable plate 7. A sliding rod 72 is slidably connected to the inner wall of the sliding groove 71. A block 73 is fixedly connected to one end of the sliding rod 72. A first spring 74 is movably connected to the other end of the sliding rod 72. One end of the first spring 74 is fixedly connected to the inner wall of the sliding groove 71. A lever 75 is fixedly connected to the top surface of the sliding rod 72. The top end of the lever 75 extends above the lower leg movable plate 7.

[0040] Specifically, when a rehabilitation patient needs to sit up, the electric push rod 10 pushes the upper body movable plate 5 to rotate around the hinge point with the fixed plate 4, thereby adjusting the angle of the patient's upper body. Then, the lever 75 is pulled, and the lever 75 drives the slide rod 72 to slide in the slide groove 71. While the slide rod 72 is sliding, on the one hand, the first spring 74 is compressed, and on the other hand, the block 73 is moved, causing the block 73 to leave the inside of the moving groove 13, thereby releasing the limitation of the bed frame 1 on the lower leg movable plate 7. This allows the lower leg movable plate 7 to rotate downward to a vertical state through the hinge point with the thigh movable plate 6, simulating the leg state of the patient in a natural sitting posture. This helps the patient better adapt to the body posture in daily activities and provides positive support for the patient's rehabilitation process.

[0041] In a further embodiment, servo motors 81 are fixedly installed on both sides of the transmission groove of the bed frame 1. A lead screw 82 is fixedly sleeved on the output shaft of the servo motor 81. One end of the lead screw 82 is rotatably connected to the inner wall of the transmission groove. A threaded sleeve 83 is threaded on the outer surface of the lead screw 82. A support column 84 is fixedly connected to one side of the threaded sleeve 83. A telescopic column 85 is slidably connected to the inner wall of the support column 84. A connecting block 86 is fixedly connected to the top of the telescopic column 85. An exercise rod 87 is fixedly connected to one side of the connecting block 86. Several limiting holes 851 are opened on one side of the telescopic column 85. A pull rod 88 is slidably connected to the side wall of the support column 84. One end of the pull rod 88 passes through the side wall of the support column 84 and extends to the inner wall of the limiting hole 851. A second spring 89 is sleeved on the outer surface of the pull rod 88.

[0042] Specifically, when a patient needs to perform upper limb rehabilitation exercises, the servo motor 81 is activated, and its output shaft drives the lead screw 82 to rotate. The screw sleeve 83 will move axially on the lead screw 82, and the support column 84 will move synchronously with the screw sleeve 83, thereby adjusting the position of the exercise rod 87 in the horizontal direction to adapt to the exercise needs of different patients.

[0043] When the height of the exercise rod 87 needs to be adjusted, pull the lever 88 outward so that one end of it is pulled out of the limiting hole 851 of the telescopic column 85. At this time, the telescopic column 85 can slide freely on the inner wall of the support column 84. After adjusting the telescopic column 85 to a suitable height, release the lever 88. Under the elastic force of the second spring 89, one end of the lever 88 is reinserted into the corresponding limiting hole 851, thereby fixing the height of the telescopic column 85 and adjusting the height of the exercise rod 87.

[0044] In a further embodiment, each of the four corners of the bottom of the bed frame 1 is fixedly connected with a support leg 11, and a base plate 12 is fixedly connected to the inside of the support leg 11. An electric push rod 10 is fixedly installed on the top of the base plate 12.

[0045] Specifically, the outrigger 11 provides a stable support structure to ensure the stability of the entire rehabilitation and nursing device during use, and the base plate 12 provides an installation foundation for the electric push rod 10, playing a certain protective and fixing role to prevent it from shifting or loosening during use.

[0046] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
