[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example Reference Figures 1-6 The present invention provides a technical solution: a bed with an adjustable pad for hemodialysis, comprising a bed frame 1, a first pad 2, a second pad 3, a secondary adjustment mechanism 5, and a pad adjustment mechanism 4. The pad adjustment mechanism 4 includes a push rod 41, which is installed below the first pad 2, and a rectangular plate 411 is installed at the bottom of the push rod 41. An electric telescopic rod 42 is installed below the rectangular plate 411, and the telescopic end of the electric telescopic rod 42 is connected to the rectangular plate 411. A curved rod 43 is disposed on one side of the rectangular plate 411. The secondary adjustment mechanism 5 is disposed at one end of the bed frame 1 for adjusting the angle of the second pad 3.

[0023] By installing an electric telescopic rod 42 at the bottom of the bed frame 1, the telescopic end of the electric telescopic rod 42 pushes the rectangular plate 411 to move. While driving the push rod 41 to move upward, it also drives the curved rod 43 to move upward. The push rod 41 and the curved rod 43 will push different positions on the first pad 2, which can adjust the position and posture of the patient's feet and lower legs, relieve the patient's discomfort, and enable the patient to calmly perform dialysis.

[0024] In a preferred embodiment, the secondary adjustment mechanism 5 includes a lead screw 51, a first support rod 52, and a slide rod 53. The lead screw 51 is rotatably mounted on the inner side of the bed frame 1, and a threaded sleeve is threadedly connected to the lead screw 51. A connecting block 6 is stably mounted on the outside of the threaded sleeve. The first support rod 52 is rotatably mounted on the outer surface of the connecting block 6, and the first support rod 52 is rotatably connected to the second pad 3. The slide rod 53 is also fixedly mounted on the inner side of the bed frame 1. A rectangular block 7 is slidably mounted on the outer surface of the slide rod 53. A connecting plate 8 is provided between the rectangular block 7 and the connecting block 6, and is stably connected to the connecting plate 8. A support rod 23 is also rotatably mounted on the rectangular block 7, and the support rod 23 is rotatably connected to the second pad 3. A support seat 9 is fixedly mounted at the bottom of the bed frame 1, and a servo motor 10 is stably mounted on the upper surface of the support seat 9. The output end of the servo motor 10 is located at one end of the lead screw 51.

[0025] When in use, this device can also adjust the patient's back, allowing the patient to maintain a leaning position during dialysis, changing the patient's posture on the bed, and relieving the patient's discomfort. The second pad 3 is rotatably connected to the middle connecting plate 11. When the second pad 3 is in a horizontal state, it can be flush with the upper surface of the middle connecting plate 11. In addition, the control switch of the servo motor 10 is installed on the bed frame 1.

[0026] When the patient needs to adjust the rotation of the second pad 3, they can directly press the control switch. The servo motor 10 drives the lead screw 51 to rotate. The rotation of the lead screw 51 drives the linkage block 6 to move. The linkage block 6 is connected to the rectangular block 7 through the connecting plate 8, so that the linkage block 6 does not rotate with the lead screw 51. The device has connecting plates 8 installed on both sides of the linkage block 6. Each connecting plate 8 is equipped with a rectangular block 7. The rectangular block 7 slides on the slide rod 53. The linkage block 6 drives the two rectangular blocks 7 to move simultaneously, and controls the first support rod 52 and the support rod 23 to lift the second pad 3 at the same time, so that the second pad 3 can be controlled to rotate upward. The rotation angle of the second pad 3 is controlled by the patient, so that the patient can lean on the second pad 3 to perform dialysis.

[0027] This device has an intermediate connecting plate 11 on the bed frame 1, which is rotatably connected to the first pad 2 and the second pad 3 respectively. The interior of the bed frame 1 is hollow. The headboard 12 and the footboard 13 are also stably installed at the ends of the bed frame 1. The intermediate connecting plate 11 is stably installed on the bed frame 1, so the first pad 2 and the second pad 3 can be rotated stably. The state of the first pad 2 and the second pad 3 can be changed according to the patient's needs, so that the patient can lie in bed and perform dialysis in peace.

[0028] The first pad 2 is configured as a multi-segment plate with rotating connection, and a limiting plate 14 is rotatably connected to the tail end of the first pad 2. A sliding rod 15 is fixedly installed inside the bed frame 1 and inserted into the limiting plate 14, controlling the sliding connection between the limiting plate 14 and the sliding rod 15. The multi-segment plate with rotating connection means that the first pad 2 contains several plates, and each plate is connected by a round shaft. In this way, when in use, pushing different plates can adjust different positions on the patient's body. For example, when pushing the plate corresponding to the patient's foot position, the plate is pushed up by the electric telescopic rod 42, which can push the patient's foot upward. When pushing the plate corresponding to the patient's knee position, it will change the posture of the patient's lower leg, thereby changing the posture of the patient's legs and relieving the patient's discomfort.

[0029] A table adjustment mechanism 16 is also provided on the outside of the bed frame 1. The table adjustment mechanism 16 includes a connecting rod 161, a middle plate 162, a table 163, and a traction rod 164. The connecting rod 161 is movably installed on the outer surface of the second pad 3. A drive rod 17 is sleeved on one end of the connecting rod 161 and rotatably connected to the connecting rod 161. The drive rod 17 is rotatably connected to the middle plate 162, and a through groove is provided at one end of the middle plate 162. One end of the middle plate 162 is also rotatably connected to the traction rod 164. A moving block 18 is slidably provided on the outside of the bed frame 1, and the traction rod 164 is stably connected to the moving block 18. A sliding groove 19 is opened on the outer surface of the bed frame 1, and several sliders are provided inside the sliding groove 19. Each slider is stably connected to the corresponding moving block 18. A second support rod 20 is fixedly installed on the top of the moving block 18, and a handrail 21 is fixedly installed on the top of the second support rod 20.

[0030] While controlling the second pad 3 to rotate upward, this device can also drive the armrest 21 to move. The device has a rotatable connecting rod 161 installed on the outer side of the second pad 3. The connecting rod 161, the intermediate plate 162, the drive rod 17 and the traction rod 164 are all movably connected. In this way, when the second pad 3 moves upward, the connecting rod 161 will drive the drive rod 17, the intermediate plate 162 and the traction rod 164 to move in sequence. This can pull the moving block 18 to move on the bed frame 1 and move the armrest 21 to a position closer to the patient. This way, the patient's arm can be placed on the armrest 21, so that the patient does not stay in one position all the time and cause physical discomfort.

[0031] A detachable table 163 is installed on the handrail 21. A snap-fit ​​sleeve 22 is provided at the bottom of the table 163, and the snap-fit ​​sleeve 22 is snapped to the handrail 21. Similarly, the table 163 will also move together with the handrail 21. The table 163 is controlled to move to a position closer to the patient, so that the patient can play mobile phone, read books, etc. on the table 163. By diverting the patient's attention, the patient's discomfort is relieved.

[0032] Specifically, the working process or principle of a hemodialysis bed with an adjustable cushion frame is as follows: During hemodialysis treatment, which typically lasts four hours, patients may experience discomfort due to maintaining one posture while lying in bed, requiring adjustment. The common method is to adjust the backrest of the bed, raising it to change the patient's posture and alleviate discomfort. However, this method only adjusts the back, not the legs, still affecting the patient's comfort. Therefore, this device was designed to solve this problem.

[0033] This device can use an electric telescopic rod 42 to push the rectangular plate 411 upward and control the push rod 41 to move upward. At the same time, the rectangular plate 411 will also push the curved rod 43 upward, which can push the first pad 2 to rotate, thereby supporting the patient's legs and changing the patient's leg position, such as from horizontal to bent, so as to change the patient's leg posture on the hospital bed and improve the patient's comfort during hemodialysis. Specifically, when this device is in use, a hemodialysis machine will be placed next to it. The patient sits on the hospital bed from the unobstructed place next to the armrest 21, and then can lie on the hospital bed to wait for medical staff to perform hemodialysis.

[0034] Because the needle placement during hemodialysis varies from person to person, when the needle is in the arm, the arm cannot move too much, otherwise it will affect the dialysis treatment. When lying in bed, patients inevitably feel uncomfortable due to the fixed lying position, and the arm is connected to the needle tube. To reduce the range of motion required to adjust body posture, the switch of servo motor 10 can be pressed. Servo motor 10 drives lead screw 51 to rotate, which in turn drives threaded sleeve to move. During the movement of threaded sleeve, it controls the first support rod 52 to push the second pad 3 to rotate upward. At the same time, the linkage block 6 moves, which also drives the rectangular block 7 to slide on the slide rod 53. The rectangular block 7 and the linkage block 6 move in the same direction. During this process, the support rod 23 also rotates. The support rod 23 and the first support rod 52 together push the second pad 3 upward, which can change the second pad 3 from a horizontal state to an inclined state, so that the patient is not lying flat, thus adjusting the patient's lying position in the bed and relieving the patient's discomfort.

[0035] Furthermore, while controlling the rotation of the second pad 3, this device will also drive the armrest 21 to move. The upward rotation of the second pad 3 will pull the connecting rod 161 to rotate. Under the traction of the connecting rod 161, the drive rod 17 will also rotate, thereby pulling the intermediate plate 162 to move. Both ends of the intermediate plate 162 are rotatably connected to the drive rod 17 and the traction rod 164. The rotation of the intermediate plate 162 will pull the traction rod 164 to move horizontally outside the bed frame 1. The traction rod 164 will pull the moving block 18 and the armrest 21 to move together, moving the armrest 21 closer to the patient's position. When the patient leans on the second pad 3, the arm without needles can rest on the armrest 21, changing the body posture and reducing the patient's discomfort.

[0036] In addition, a table 163 will be installed on the handrail 21. When the handrail 21 moves, the table 163 will also move, so that the table 163 is closer to the patient's body. In actual use, the patient can rest the arm that is not receiving injections on the table 163 to operate mobile phones and other items, which is convenient for operation.

[0037] To avoid accidents during hemodialysis, patients lie carefully in bed. Since dialysis lasts for four hours, lying in bed for a long time can cause discomfort not only in the arms but also in the legs. Therefore, this device can also adjust the patient's leg posture. By extending the telescopic end of the electric telescopic rod 42, it pushes the rectangular plate 411 upward. The push rod 41 on the rectangular plate 411 pushes one of the plates on the first pad 2 upward. During the movement, it also pulls the limiting plate 14 to move, pushing one of the plates upward, which moves the patient's foot position upward, that is, lifts the patient's leg. This can change the patient's leg posture to relieve the discomfort caused by the body.

[0038] Moreover, as the rectangular plate 411 moves upward, it also drives the curved rod 43 to move upward. The curved rod 43 pushes another plate on the first pad 2 to move upward. At this time, the patient's knee position will bend, which changes the posture of the patient's lower leg. After the patient's leg is raised, it can maintain the state, or it can control the electric telescopic rod 42 to perform telescopic movements, controlling the patient's leg to move up and down repeatedly for leg activities.

[0039] Finally, this device can alleviate the physical discomfort caused by prolonged lying down during dialysis, providing some relief to the already uncomfortable body.
