[0002] With the development of medical technology, medical beds, as essential medical equipment commonly used in hospitals and rehabilitation institutions, are constantly improving in terms of functionality and intelligence. Existing medical beds mainly possess basic functions such as lifting, tilting, and backrest elevation. However, in actual medical and rehabilitation processes, patients often require procedures such as disinfection, acupuncture-assisted therapy, and upper limb rehabilitation training. Traditional medical beds cannot integrate these multiple functions, leading to frequent patient movement during treatment or rehabilitation, increasing the workload of nursing staff and affecting patient comfort and treatment effectiveness. Furthermore, existing medical beds lack dedicated disinfection and resistance adjustment devices for acupuncture-assisted therapy and upper limb rehabilitation training, resulting in cumbersome disinfection procedures and difficulty in adjusting rehabilitation training resistance, reducing medical efficiency and patient experience. Therefore, developing a new type of medical bed that integrates multiple functions, has a compact structure, and is easy to operate has become an urgent technical problem to be solved in the field of medical devices.

[0003] Existing medical beds cannot integrate multiple functions such as height adjustment, tilting, disinfection, acupuncture-assisted treatment, and upper limb rehabilitation training. This results in cumbersome and inefficient operation during patient treatment and rehabilitation.

[0010] Furthermore, the training unit also includes a liquid-pushing component rotatably disposed inside the storage tank, and the liquid-pushing component is connected to a rotary pusher. The liquid-pushing component includes: The force transmission rod is symmetrically fixed with support plates on its outer side, and the support plates are located inside the storage tank; The resistance plate has two plates, which are symmetrically arranged inside the storage tank; The end of the resistance plate near the force transmission rod is fixedly connected to the support plate.

[0011] Furthermore, the pusher includes: The handle is fixed to the end of the force transmission rod away from the storage tank. Supports are symmetrically fixed to the outside of the handle; The pad is fixed to the inside of the support.

[0012] Furthermore, the resistance adjustment section also includes a secondary pusher disposed within the storage tank, and the secondary pusher is connected to the adjustment puller. The secondary pusher includes: The support plate is fixed inside the storage tank and located between two pairs of paddles, with a gap between it and the force transmission rod.

The cotton sleeve is then removed for alcohol disinfection of the patient's skin or acupuncture needles. Adjust the rotation position and height of the storage cylinder and the force transmission rod so that the handle and the support are in a suitable position for the patient's arm. The patient holds the handle or places his forearm on the support and pushes or pulls the handle to rotate the force transmission rod, which in turn rotates the resistance plate to achieve upper limb rehabilitation training. Adjusting the position of the pull-out component changes the movement state of the paddle inside the storage tank, thereby flexibly adjusting the rotational resistance during rehabilitation training to meet the rehabilitation resistance needs of different patients. After use, reset all components, turn off the electric push rod and motor, and ensure that the medical bed and its auxiliary functional components are in a safe standby state.

[0016] The above-described solution of the present invention has at least the following beneficial effects: The built-in alcohol storage and conduction structure in the disinfection and storage section enables immediate disinfection of acupuncture needles and rapid disinfection of the patient's skin. At the same time, the rehabilitation and training section, combined with the liquid resistance in the storage cylinder and the paddle in the resistance adjustment section, allows patients to perform upper limb rehabilitation training with adjustable resistance directly on the hospital bed, significantly improving treatment continuity, reducing equipment transfer time, and optimizing clinical operation procedures.

[0019] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0020] like Figures 1 to 11 As shown, an embodiment of the present invention provides a tiltable and height-adjustable medical bed, comprising a bed frame 1 and a bed frame 4 disposed above the bed frame 1. Support rods 2 are symmetrically and rotatably connected to the inner side of the bed frame 1. A secondary rod 3 is rotatably connected to the inner side of the support rod 2. The upper ends of the secondary rod 3 and the support rod 2 are rotatably and slidably connected to the inner side of the bed frame 4, and the secondary rod 3 and the support rod 2 are Y-shapedly fitted. Electric push rods 6 are rotatably and symmetrically disposed below the bed frame 4. A crescent plate 7 is fixed to the outer side of the secondary rod 3, and the crescent plate 7 is rotatably connected to the telescopic end of the electric push rod 6 to adjust the height and tilt of the bed frame 4. A backrest frame 8 is disposed on the bed frame 4. A connecting frame 9 is rotatably connected to one side of the backrest frame 8. A protruding frame 10 is rotatably connected to one side of the connecting frame 9. A recessed frame 11 is spaced apart on one side of the protruding frame 10. The recessed frame 11 is rotatably connected to the side of the bed frame 4. The invention also includes: The disinfection and storage unit is located outside the bed frame 4 and is movable and lifted. It includes a storage cylinder 16 located outside the bed frame 4 and a disinfection insert located above the storage cylinder 16 to store alcohol and acupuncture needles 54, and to use alcohol to disinfect the patient's body and disinfect the acupuncture needles 54.

[0021] The rehabilitation training section is a rotating through-storage section, which includes a resistance plate 20 rotatably disposed inside the storage cylinder 16, and a push-rotating component connected to the resistance plate 20. The push-rotating component includes a force transmission rod 18, and the force transmission rod 18 is rotatably disposed through the upper end of the storage cylinder 16 via a bearing, so as to rehabilitate and train the patient's arm. The resistance adjustment section, which runs through the rehabilitation training section, includes two pairs of paddles 25 that are movably installed inside the storage cylinder 16 and located outside the push-rotation component, as well as an adjustment pull component that runs through the push-rotation component, so as to flexibly adjust the resistance of rehabilitation training.

[0022] Specifically, the bed frame 4 is symmetrically fixed with support plates 5 below, and the support plates 5 are rotatably connected to the fixed end of the electric push rod 6. The bed frame 1 can provide rotational support for the support rod 2, the support rod 2 can provide rotational support for the auxiliary rod 3, and the auxiliary rod 3 and the support rod 2 can provide support for the bed frame 4. The bed frame 4 can provide rotational support and sliding translational guide support for the upper end of the auxiliary rod 3 and the support rod 2. The support plates 5 can provide rotational support for the electric push rod 6, and there are two electric push rods 6.

[0023] In practical application, the operator can control the two electric actuators 6 to extend simultaneously as needed. The electric actuators 6 use their telescopic ends to push the crescent-shaped plate 7. Simultaneously, the fixed end of the electric actuator 6 rotates under the support of the support plate 5, while the telescopic end rotates under the support of the crescent-shaped plate 7. This allows the electric actuator 6 to push the crescent-shaped plate 7 towards the bed frame 4. At the same time, the crescent-shaped plate 7, under external force, pushes the auxiliary rod 3, causing the auxiliary rod 3 to rotate towards the support rod 2 and the bed frame 4 under the support of the support rod 2. This causes the support rod 2 and the auxiliary rod 3 to move closer together, thus pushing the bed frame 4 upwards during this movement. When the electric actuator 6 is retracted, the auxiliary rod 3 is pulled away from the bed frame 4 via the crescent-shaped plate 7. The auxiliary rod 3, supported by the support rod 2, pulls the bed frame 4 downwards. At the same time, the two ends of the electric push rod 6 rotate under the support of the support plate 5 and the crescent plate 7, respectively. Meanwhile, the upper ends of the support rod 2 and the auxiliary rod 3 move along the bed frame 4 during the rising and falling process and rotate under the support of the bed frame 4. This allows the bed frame 4 to lower its height when the electric push rod 6 retracts. The operator can control the electric push rod 6 on one side to extend and the electric push rod 6 on the other side to retract as needed. This causes the auxiliary rod 3 and support rod 2 on one side to move closer to each other and the auxiliary rod 3 and support rod 2 on the other side to move further apart. This allows one side of the bed frame 4 to be raised while the other side of the bed frame 4 is lowered, allowing the bed frame 4 to be tilted to one side as needed.

[0024] Furthermore, a first electric telescopic rod 55 is rotatably connected to the outer side of the support plate 5, and a push arm 56 is rotatably connected to the telescopic end of the first electric telescopic rod 55. A bracket 58 is symmetrically welded to the bottom surface of the connecting frame 9. A support rod 57 is connected to the side of the bracket 58, and the support rod 57 is rotatably connected to the upper end of the push arm 56. A second electric telescopic rod 59 is rotatably connected to the outside of the support plate 5 and is arranged in the opposite direction to the first electric telescopic rod 55. The telescopic end of the second electric telescopic rod 59 is rotatably connected to a connecting arm 60, and the upper end of the connecting arm 60 is fixedly connected to the recess 11.

[0025] Specifically, the support plate 5 provides rotational support for the first electric telescopic rod 55. The first electric telescopic rod 55 can push or pull the push arm 56 with its telescopic end, so that the push arm 56 can push the bracket 58 to move through the support rod 57. At the same time, the support rod 57 can provide rotational support for the push arm 56, so that the bracket 58 can drive the connecting frame 9 to move. The second electric telescopic rod 59 can provide rotational support for the connecting arm 60 under the support of the support plate 5. The connecting arm 60 can provide support for the recessed frame 11. The second electric telescopic rod 59 can push or pull the connecting arm 60 with its telescopic end. The lower end of the connecting arm 60 can rotate under the support of the second electric telescopic rod 59. It can also push and pull the recessed frame 11 to rotate under the support of the bed frame 4 with external force. The recessed frame 11 is connected to the bed frame 4 through a rotating connecting component.

[0026] The bed frame 4 has detachable and symmetrical I-beams 61 on both sides via fixing components. A table 62 is inserted into the I-beams 61 and the table 62 is located above the connecting frame 9. A bottle holder 63 is provided on the recessed frame 11 away from the tabletop 62, and the bottle holder 63 is connected to the bed frame 4. Folding armrests 64 are symmetrically provided on both sides of the backrest frame 8 and the recessed frame 11. Specifically, the bed frame 4 provides stable support for the I-beam board 61, the I-beam board 61 provides space and support for the table board 62, the table board 62 provides space for the patient's daily necessities for use in bed, the bed frame 4 provides stable support for the IV drip holder 63, the IV drip holder 63 provides suspension support for the IV drip, making it convenient to hang the IV drip for the patient to receive infusions, and the folding handrail 64 can be folded and retracted or unfolded for protection under the support of the bed frame 4. The folding handrail 64 in the folded state does not affect the use of the force transmission rod 18. Staff can install or remove the I-beam board 61 using the fixed parts as needed. Before installing the I-beam board 61, the heat storage unit needs to be removed first.

[0027] In practical application of this embodiment: the first electric telescopic rod 55 is in a retracted state when the backrest frame 8, connecting frame 9, concave frame 11, and convex frame 10 are in a straight state, while the second electric telescopic rod 59 is in an extended state. The operator can control the extension of the first electric telescopic rod 55 according to actual needs, allowing the first electric telescopic rod 55 to push the push arm 56 using its telescopic end. Simultaneously, the lower end of the push arm 56 will rotate under the support of the telescopic end of the first electric telescopic rod 55 during movement, while the upper end of the push arm 56 will rotate around the support rod 57 with the support rod 57 as its center. At the same time, the fixed end of the first electric telescopic rod 55 will rotate under the support of the support plate 5. The operator needs to simultaneously control the retraction of the second electric telescopic rod 59, allowing the second electric telescopic rod 59 to utilize... The telescopic end pulls the connecting arm 60, causing the lower end of the connecting arm 60 to rotate under the support of the telescopic end of the second electric telescopic rod 59 during its retraction and movement. This allows the connecting arm 60 to drive the concave frame 11 to rotate and tilt (to the left) under the support of the bed frame 4 using the rotating connecting component, providing support for the patient's lower legs. During the rotation of the connecting frame 9, the protruding frame 10 and the backrest frame 8 will rotate, causing the protruding frame 10 to tilt to the right to provide support for the patient's thighs, the connecting frame 9 to provide support for the patient's buttocks, and the backrest frame 8 to tilt to the left to provide support for the patient's back. At the same time, the staff can control the extension and retraction of the electric push rod 6 as needed to adjust the overall tilt of the bed frame 4. Through the above flexible adjustments, the patient can maintain a suitable and comfortable angle and posture.

[0028] When the backrest angle needs to be adjusted to achieve the backrest lifting action, the first electric telescopic rod 55 starts and extends, and its telescopic end pushes the push arm 56 to rotate around the connection point on the side of the support plate 5. The push arm 56 drives the bracket 58 to move through the support rod 57. Since the bracket 58 is welded to the connecting frame 9 as a whole, it drives the connecting frame 9 to rotate around the hinge point with the backrest frame 8. At the same time, the connecting frame 9 drives the protrusion 10 to move synchronously. Meanwhile, the second electric telescopic rod 59 starts and retracts synchronously, and its telescopic end pulls the connecting arm 60 to rotate around the connection point on the side of the support plate 5. The connecting arm 60 drives the concave frame 11 fixed to it to rotate around the hinge point with the bed frame 4. The concave frame 11 forms a closed loop linkage with the connecting frame 9 and the backrest frame 8 through the protrusion 10, ensuring that the backrest frame 8 is raised smoothly during the backrest lifting process, so that the patient can maintain a comfortable posture, provide reasonable support for the patient's buttocks, back and legs, without jamming or impact, and with small relative displacement between the patient's back and buttocks, improving the comfort of use. When the backrest needs to be flattened to return to its initial state, the first electric telescopic rod 55 retracts and the second electric telescopic rod 59 extends. The two sets of components move in opposite directions, driving the four-bar linkage to reset, and the backrest frame 8 is flattened smoothly.

[0029] In a preferred embodiment of the present invention, the alcohol storage section further includes a storage member disposed outside the alcohol insertion member to store alcohol. The storage member includes: A threaded cap 17 is threaded through the upper end of the storage cylinder 16; Fixed plate 12 is connected to the bottom of bed frame 4; The electric pole 13 is fixed to the outside of the fixed plate 12; The lifting rod 14 is fixed to the telescopic end of the electric rod 13, and its telescopic end is fixedly connected to the storage tank 16 through a connecting component.

[0030] Specifically, the fixed plate 12 is detachably connected to the bed frame 4 via a fixing component. The telescopic end of the lifting rod 14 is fixed with a connecting plate 15, and the connecting plate 15 is fixedly connected to the upper end of the storage cylinder 16 via a fixing component. The fixed plate 12 can provide stable support for the electric rod 13 under the support of the bed frame 4. The electric rod 13 can provide support for the lifting rod 14, so that the lifting rod 14 can provide stable support for the storage cylinder 16 through the connecting plate 15 and the fixing component. Under the control of the operator, the electric rod 13 can push the storage cylinder 16 to move away from the bed frame 4 through the lifting rod 14 and the connecting plate 15. Under the control of the operator, the lifting rod 14 can push the storage cylinder 16 to adjust its height through the connecting plate 15. The storage cylinder 16 can provide storage space for alcohol.

[0031] The plug-in components include: The inner cavity 26 is opened on the inner side of the force transmission rod 18 and is located inside the storage cylinder 16; The passage 27 has two openings, through which the force transmission rod 18 passes and is connected to the inner cavity 26; Sleeve 47 is installed through one side of force transmission rod 18; The cotton seat 48 is fixed inside the sleeve 47; The wick 49 is connected to the lower end of the wick holder 48 and extends into the inner cavity 26; The sterilized parts are inserted into the sleeve 47.

[0032] Specifically, the force transmission rod 18 provides opening space for the inner cavity 26 and the passage 27, and the passage 27 and the inner cavity 26 provide flow storage space for alcohol. The force transmission rod 18 can stably support the sleeve 47, and the sleeve 47 can provide support for the cotton seat 48, so that the cotton seat 48 can stably support the wick cotton 49. The wick cotton 49 and the cotton seat 48 have adsorption properties and can absorb and conduct alcohol.

[0033] The sterilization components include: Threaded plug 50 is threadedly connected to the end of sleeve 47; Support column 51 is fixed to one end of threaded plug 50 and located inside sleeve 47; The cotton cover 53 is fixed to the outside of the support column 51 by a fixing component; Acupuncture needle 54 is inserted through a threaded plug 50 into a cotton sleeve 53.

[0034] Specifically, a bolt 52 is provided through the inside of the cotton sleeve 53, and the bolt 52 is threadedly connected to the support column 51. The sleeve 47 can provide support for the threaded plug 50 by means of the thread. The threaded plug 50 can stably support the support column 51. The support column 51 can provide fixed support for the cotton sleeve 53 by means of the bolt 52. The cotton sleeve 53 can absorb alcohol in the cotton seat 48 and can provide an insertion space and support positioning function for the acupuncture needle 54. The threaded plug 50 can provide a through channel and positioning support for the acupuncture needle 54.

[0035] In practical application, the staff can insert the acupuncture needle 54 through the threaded plug 50 into the cotton sleeve 53 for storage, so that the cotton sleeve 53 can wrap the acupuncture needle 54. At the same time, before using the medical bed, the staff can use the threaded action to remove the threaded cap 17, open the opening on the storage cylinder 16, and then inject alcohol into the storage cylinder 16 for storage. The storage cylinder 16 and the force transmission rod 18 are made of medical stainless steel, and the alcohol will pass through the passage 27 from the storage cylinder 16 into the inner cavity 26. The wick cotton 49 will absorb the alcohol in the inner cavity 26 and pass through the passage 27 to the cotton seat 48. The cotton seat 48 will absorb the alcohol and become moist. When the cotton sleeve 53 is inserted into the sleeve 47, it will contact the cotton seat 48, absorb and carry the cotton sleeve. When staff need to disinfect the patient's skin on the medical bed or perform acupuncture as an adjunct treatment, they can control the electric rod 13 to extend as needed, pushing the storage cylinder 16 to move forward horizontally. Then, they can control the lifting rod 14 to extend, raising the storage cylinder 16 to a suitable height. After that, they can push the threaded plug 50 to rotate under the support of the sleeve 47, causing the threaded plug 50 to separate from the sleeve 47 using the thread action. At the same time, they can pull the threaded plug 50 away from the sleeve 47, allowing the threaded plug 50 to pull the cotton sleeve 53 out from the inside of the sleeve 47 through the support column 51 and bolt 52. The cotton sleeve 53, which carries alcohol, can then be rubbed on the patient's skin that needs disinfection, allowing the alcohol to be applied to the patient's skin for disinfection. The cotton sleeve 53 provides support and positioning for the acupuncture needle 54 and can also wrap and protect the acupuncture needle 54. The alcohol absorbed by the cotton sleeve 53 will come into contact with the acupuncture needle 54 through conduction, thereby using the alcohol to disinfect the acupuncture needle 54, saving the disinfection process before the acupuncture needle 54 is used. After adjusting the position of the storage cylinder 16, and before rotating and removing the threaded plug 50, the staff can pull the acupuncture needle 54 through the threaded plug 50 away from the cotton seat, so that the acupuncture needle 54 can be pulled out of the cotton sleeve 53 and removed through the threaded plug 50 to the outside. After that, the staff can directly use the acupuncture needle 54 to perform acupuncture on the patient as an adjunct treatment.

[0036] In a preferred embodiment of the present invention, the training unit further includes a liquid-pushing component rotatably disposed inside the storage tank 16, and the liquid-pushing component is connected to the rotary pusher. The liquid-pushing component includes: A support plate 19 is symmetrically fixed on the outer side of the force transmission rod 18, and the support plate 19 is located inside the storage cylinder 16; There are two resistance plates 20, which are symmetrically arranged inside the storage tank 16; The end of the resistance plate 20 near the force transmission rod 18 is fixedly connected to the support plate 19.

[0037] Specifically, the force transmission rod 18 can provide stable support for the support plate 19, the support plate 19 can provide support for the resistance plate 20, the storage cylinder 16 can provide rotation space for the resistance plate 20, and the storage cylinder 16 can provide rotational support for the force transmission rod 18 through the bearing.

[0038] The push-spin component includes: Handle 44 is fixed to the end of force transmission rod 18 away from storage cylinder 16; Support 45 is symmetrically fixed to the outside of handle 44; Pad 46 is fixed inside the support 45.

[0039] Specifically, the force transmission rod 18 can provide support for the handle 44, the handle 44 can provide support for the support 45, so that the support 45 can support the pad 45, the pad 46 and the support 45 can provide a place for the patient's forearm, and the handle 44 can make it convenient for the patient to push the force transmission rod 18 with their hands.

[0040] In practical application, when rehabilitation training for a patient's upper limbs is required, staff can control the extension and retraction of the electric rod 13 and the lifting rod 14 as needed, while simultaneously pushing the force transmission rod 18 to move it from one position to the other. Figure 6 Rotate 90 degrees counterclockwise at the position shown until... Figure 7 The state shown allows the reservoir 16 to adjust the force transmission rod 18 and handle 44 to a suitable position and height, making it convenient for the patient to push the handle 44 with their hand and forearm. The patient lying on the medical bed can then hold the handle 44 or support their forearm on the inside of the support pad 46 and push the handle 44 with their hand or the support pad 46 and the support 45. This allows the handle 44 to push the force transmission rod 18 to rotate counterclockwise around the bearing with the support of the reservoir 16, or to pull the force transmission rod 18 to rotate clockwise with the support of the reservoir 16. At the same time, the force transmission rod 18 will drive the resistance plate 20 to rotate clockwise or counterclockwise through the support plate 19. This allows the resistance plate 20 to push the alcohol in the reservoir 16 during rotation, using the alcohol to provide rotational resistance for the resistance plate 20. This resistance can then be used to train the patient's upper limb strength, facilitating upper limb rehabilitation training.

[0041] In a preferred embodiment of the present invention, the resistance adjustment unit further includes a secondary pusher disposed within the storage cylinder 16, and the secondary pusher is connected to the adjustment puller. The secondary pusher includes: The support plate 21 is fixed inside the storage tank 16 and located between the two pairs of paddles 25, with a gap 22 between it and the force transmission rod 18. Two support rings 23 are arranged longitudinally and fixed to the outside of the force transmission rod 18; The support ring 23 is located below the support plate 19, and the two support rings 23 are respectively fixed to the ends of the two pairs of paddle plates 25; The insert is provided with a through-hole support ring 23 and a force transmission rod 18.

[0042] Specifically, the storage tank 16 can provide stable support for the support plate 21, the support plate 21 can provide a through channel for the force transmission rod 18 and the alcohol, the force transmission rod 18 can provide a limiting function for the support ring 23, the support ring 23 can provide opening space for the insertion hole 24, and the support ring 23 can stably support the paddle plate 25.

[0043] Connector components include: The insertion hole 24 and the through support ring 23 are symmetrically arranged; There are two connecting plates 30, which are respectively set through two passages 27 and are elastically connected to the inner wall of the force transmission rod 18. There are two collars 31, which are sleeved on the outside of the force transmission rod 18 and fixedly connected to the two connecting plates 30 respectively. The insertion rod 32 is symmetrically fixed below the collar 31, and corresponds to the position of the insertion hole 24, and is located above the insertion hole 24.

[0044] Specifically, a support block 28 is arranged longitudinally inside the cavity, and the support block 28 is connected to the inner wall of the force transmission rod 18. A spring 29 is fixed to the lower end of the support block 28, and the lower end of the spring 29 is fixedly connected to the connecting plate 30. The collar 31 can provide support for the insertion rod 32 under the support of the connecting plate 30. The insertion hole 24 can provide an insertion channel for the insertion rod 32, so that the insertion rod 32 can be inserted and connected to the support ring 23.

[0045] Adjustable pull parts include: The inner cavity 26 is provided with a first arc head plate 33 and a second arc head plate 36. The first arc head plate 33 and the second arc head plate 36 are fixedly connected to the inner wall of the force transmission rod 18, and the second arc head plate 36 is located on one side of the first arc head plate 33. The inside of the force transmission rod 18 is provided with a wire groove 34 and a wire channel 37, and the wire groove 34 and the wire channel 37 are connected to the inner cavity 26; The perforation 41 has two locations, which are opened above the force transmission rod 18 and are respectively connected to the wire groove 34 and the wire channel 37; The first steel wire rope 35 is movably installed through one of the through holes 41 and the wire groove 34, and extends into the inner cavity 26, and wraps around the lower end of the first arc head plate 33 in a U-shape, and the lower end is fixedly connected to one of the connecting plates 30. The second steel wire rope 38 is movably installed through another through hole 41 and line channel 37, and extends into the inner cavity 26, and wraps around the lower end of the second arc head plate 36 in a U-shape, and the lower end is fixedly connected to another connecting plate 30. Nut 39, having two, is threadedly connected to the outside of the force transmission rod 18 and located outside the through hole 41; The inner side of one of the nuts 39 is fixed to the upper end of the first wire rope 35, and the inner side of the other nut 39 is fixed to the upper end of the second wire rope 38.

[0046] Specifically, the force transmission rod 18 provides stable support for the first arc-shaped end plate 33 and the second arc-shaped end plate 36. The first arc-shaped end plate 33 provides a resisting support for the first wire rope 35, allowing the first wire rope 35 to change its direction of movement. The second arc-shaped end plate 36 provides a resisting support for the second wire rope 38, allowing the second wire rope 38 to change its direction of movement. One end of the nut 39 is inlaid with an inner bearing 40, and there is a gap between the inner bearing 40 and the force transmission rod 18. The upper ends of the first wire rope 35 and the second wire rope 38 are connected to the inner side of the inner bearing 40. The outer side of the force transmission rod 18 has two threaded grooves 42, and the threaded grooves 42 are respectively connected to... The nut 39 is threaded, providing a channel for the nut 39 to rotate and move. A retaining ring 43 is fixed to the outside of the force transmission rod 18, and the retaining ring 43 is located between two threaded grooves 42 to block one of the nuts 39 away from the handle 44, while the handle 44 can block the other nut 39. The groove 34 can provide a moving channel for the first wire rope 35, and the channel 37 can provide a moving channel for the second wire rope 38. The through hole 41 can provide a channel for the upper ends of the first wire rope 35 and the second wire rope 38 to pass through the force transmission rod 18, so that the upper ends of the first wire rope 35 and the second wire rope 38 can be connected to the two nuts 39 respectively.

[0047] In practical application, during upper limb rehabilitation training, the patient can push one of the nuts 39 to rotate as needed. This causes the nut 39 to move towards the retaining ring 43 during rotation, utilizing the threaded action with the threaded groove 42. The nut 39 is then tightened to contact the retaining ring 43. During rotation, the nut 39 pulls the first steel wire rope 35 via the inner bearing 40. Simultaneously, the inner bearing 40 maintains its position under the weight of the first steel wire rope 35, preventing the first and second steel wire ropes 35 from rotating with the nut 39. This allows one of the nuts 39 to move towards the retaining ring 43. During the movement towards the retaining ring 43, the inner bearing 40 pulls the first steel wire rope 35, allowing the first steel wire rope 35 to pass through the through hole 41 and along the wire groove 34. Supported by the force transmission rod 18 and the first arc-shaped plate 33, the first steel wire rope 35 pulls one of the connecting plates 30, causing the connecting plate 30 to move downwards along the passage 27. Simultaneously, the connecting plate 30 uses external force to pull the spring 29 downwards, causing the spring 29 to stretch downwards under the support of the support block 28. At the same time, the connecting plate 30 drives one of the collars 31 and the connected insertion rod 32 to move downwards, allowing the insertion rod 32 to be inserted into the insertion hole 24 below it. The insert ring 23 allows the force transmission rod 18 to rotate during the process of being pushed, through the connecting plate 30, collar 31, and insert rod 32, to push the support ring 23 and paddle 25 to rotate together. This allows one pair of paddles 25 to rotate together with the resistance plate 20 along with the force transmission rod 18, thereby increasing the contact area between the paddles 25 and the alcohol, based on the resistance plate 20, thus increasing the resistance to pushing the force transmission rod 18. The other nut 39, the second wire rope 38, and the other pair of paddles 25 are used in the same way as the first wire rope 35, one of the nuts 39, and one pair of paddles 25 (the other nut 39 is connected to the thread). During the rotation of the groove 42, it needs to rotate and move towards or away from the handle 44. Rotating and moving towards the handle 44 will pull the other connecting plate 30 downward, thus allowing the patient to adjust the pushing resistance as needed during upper limb rehabilitation training, increasing the training intensity and effect. When the nut 39 moves away from the retaining ring 43 or the handle 44, it will loosen the first wire rope 35 or the second wire rope 38. At the same time, the stretched spring 29 will rebound and reset under the support of the support block 28, and use the rebound force to pull the first wire rope 35 or the second wire rope 38 to move and reset.

[0048] As a preferred embodiment of the present invention, a method of using a tiltable and height-adjustable medical bed includes: By controlling the two electric actuators 6 to extend simultaneously, the telescopic ends of the electric actuators 6 push the crescent plate 7, causing the auxiliary rod 3 and the support rod 2 to move upward, thereby pushing the bed frame 4 to rise as a whole. By controlling the two electric actuators 6 to retract simultaneously, the crescent plate 7 and the auxiliary rod 3 move downward, thereby causing the bed frame 4 to fall as a whole. By controlling one side of the electric actuator 6 to extend and the other side to retract, the bed frame 4 can be raised on one side and lowered on the other side, thereby tilting the bed frame 4 to one side to achieve tilt adjustment. Alcohol is added to the storage cylinder 16 by removing the threaded cap 17, and the acupuncture needles 54 are inserted into the cotton sleeve 53 for storage. The extension and retraction of the electric rod 13 and the lifting rod 14 are controlled to realize the translation and lifting of the storage cylinder 16 outside the bed frame 4. The position and height of the storage cylinder 16 are adjusted, and the threaded plug 50 is rotated to separate it from the sleeve 47. The cotton sleeve 53 is pulled out for alcohol disinfection of the patient's skin or the acupuncture needles 54. Adjust the rotation position and height of the storage cylinder 16 and the force transmission rod 18 so that the handle 44 and the support pad 46 are in a suitable position for the patient's arm. The patient holds the handle 44 or places the forearm on the support pad 46. By pushing or pulling the handle 44, the force transmission rod 18 is rotated, which in turn drives the resistance plate 20 to rotate, thereby achieving upper limb rehabilitation training. Adjusting the position of the pull component changes the movement state of the paddle 25 inside the storage cylinder 16, thereby flexibly adjusting the rotational resistance during rehabilitation training to meet the rehabilitation resistance needs of different patients. After use, reset all components, turn off electric push rod 6 and electric lever 13, and ensure that the medical bed and its auxiliary functional components are in a safe standby state.
