Description

Technical Field

[0001] This invention relates to the field of rehabilitation nursing technology, specifically a rehabilitation bed for elderly patients. Background Technology

[0002] Hospital beds, also known as patient beds, medical beds, or rehabilitation and nursing beds, are beds used by patients during treatment, rehabilitation, and recuperation. They are mainly used in major hospitals, township health centers, community health service centers, rehabilitation institutions, and home-based elderly care wards.

[0003] Patent CN112972147B discloses a rehabilitation bed for elderly patients, comprising: a bed body, a front panel, a rear panel, and a lifting mechanism. In use, the lifting mechanism, activated by a motor, raises or lowers the front panel using a push block. Furthermore, the angle between the front panel and the rear panel can be adjusted according to the activation of the lifting mechanism, allowing the bed to be adjusted to allow the patient to lie down as needed, thus enabling the patient to be helped to sit up or lie down. This reduces the need for manual adjustment of the front and rear panels, thereby improving the convenience of angle adjustment.

[0004] Although the patented lifting mechanism allows the nursing bed to adjust the patient's lying angle as needed, enabling the patient to be helped up or lie down, its function is too limited and cannot meet other needs of elderly patients. For example, when an elderly person with limited mobility needs to use the toilet, the patent can only help them up, but cannot assist them in using the toilet, resulting in the lifting mechanism's function being too limited. Furthermore, existing rehabilitation beds lack sterilization measures, which increases the likelihood of illness for elderly patients and is detrimental to their recovery. Summary of the Invention

[0014] Preferably, the main frame of the hospital bed is internally fixedly connected with a mating column and an L-shaped guide frame. A limiting groove is formed on the surface of the main frame, and the lower roller slides on the surface of the limiting groove. A connecting plate and a hollow limiting plate are fixedly connected to the surface of the supporting bed board.

Several rotating shafts are provided at the connection points of the leg sponge pad, the lumbar sponge pad, and the head sponge pad.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses the extension and retraction of a cylinder to control the swing of a transmission rod, thereby achieving the lifting and lowering of the support bed board. The structure is simple and easy to operate. When the patient rises via the support bed board, it facilitates observation and diagnosis by medical staff. When the support bed board moves the patient downwards, it is closer to the ground, making it easier for the patient to move and rest. This avoids the high-intensity fatigue caused by medical staff having to bend over for extended periods during patient examinations when the bed is low, as is the case with existing technologies. It also prevents the risk of patients falling while resting or moving if the bed is high, thus facilitating diagnosis for medical staff while further improving patient protection. This invention uses a lead screw to rotate and drive a pusher block to slide, thereby controlling the lumbar sponge pad to lift to one side and thus helping the patient to sit up. At the same time, the first lead screw rotates and drives the transmission frame to slide to control the delivery of the plastic bag. The second lead screw rotates and drives the reciprocating sliding frame to slide relative to the plastic bag. The sliding shaft is magnetically attracted to the bottom of the reciprocating sliding frame. When the lead screw continues to move, the sliding shaft expands the plastic bag under the influence of the reciprocating sliding frame, increasing the range of excrement collection and further improving the excrement collection capacity. This invention compresses the air inside the pneumatic chamber to the left side of the reciprocating sliding frame, thereby compressing the air inside the piston cylinder into the liquid bottle. The disinfectant liquid inside the liquid bottle is discharged into the pneumatic chamber through air compression, and then mixed with the air output from the pneumatic chamber to form a mist for disinfection and sterilization under the patient's buttocks and around the supporting bed board, thereby reducing the risk of bacterial infection for the patient. This invention utilizes a motor reversal mechanism. The second lead screw controls the reciprocating sliding frame to reset to the left, while the first lead screw controls the transmission frame to move to the right to transport excrement inside the plastic bag. When the sliding shaft contacts the bottom of the reciprocating sliding frame, under the influence of magnetism, the sliding shaft gradually contacts the fixed shaft. The top of the plastic bag is then moistened with a disinfectant solution, and the sliding shaft and fixed shaft press against each other, thus appropriately sealing the opening of the plastic bag. This further improves the sealing of excrement and avoids the risk of bacterial infection. Simultaneously, the reciprocating vibrating shaft beats and vibrates the plastic bag containing excrement, which can collect the excrement, making it convenient for medical staff and patients' families to retrieve, accelerating the processing speed of excrement, preventing air pollution, and enhancing the patient's recovery effect.

[0024] The main frame of the hospital bed 1 is fixedly connected to a fixing block 2 and a limiting block 3; the surface of the supporting bed board 4 is rotatably connected to a flip plate 6, and the surface of the supporting bed board 4 is fixedly connected to a protective plate 5; the fixing block 2 is slidably connected to the flip plate 6, and the limiting block 3 is slidably connected to the protective plate 5; the surface of the supporting bed board 4 is fixedly connected to a leg sponge pad 7, the surface of the leg sponge pad 7 is rotatably connected to one end of a lumbar sponge pad 8, and the other end of the lumbar sponge pad 8 is rotatably connected to a head sponge pad 9.

[0025] The main frame 1 of the hospital bed is internally fixedly connected with a mating column 10 and an L-shaped guide 14. The surface of the main frame 1 of the hospital bed is provided with a limiting groove 13, and the lower roller 103 slides on the surface of the limiting groove 13. The surface of the supporting bed board 4 is fixedly connected with a connecting plate 11 and a hollow limiting plate 12.

The surface of the flipping triangular block 16 is fixedly connected with a transmission plate 18. Several rotating shafts 19 are provided at the connection points of the leg sponge pad 7, the lumbar sponge pad 8, and the head sponge pad 9.

[0026] Working principle: After the rehabilitation bed is installed, sterilization solution is added to the liquid bottle 303; the lifting component 100 raises and lowers the supporting bed board 4, allowing the patient to rise for observation and diagnosis by medical staff, and lowering the supporting bed board 4 to facilitate patient movement and rest; the adjusting component 200 adjusts the patient's lying angle and automatically assists the patient with toileting; the adjusting component 200 controls the sterilization component 300 to discharge sterilization solution, reducing the risk of bacterial infection for the patient; the sterilization component 300 controls the vibration component 400 to collect excrement after toileting, preventing the excrement from spreading and affecting the surrounding environment; The cylinder 101 is activated to retract, and the cylinder 101 drives the drive push rod 102 to slide inside the main frame of the hospital bed to control the swing of one end of the transmission rod 104. The other end of the transmission rod 104 is rotatably connected to the support bed board 4. The support bed board 4 is raised by the cooperation of the transmission rod 104 and the cooperating transmission rod 105. When rising, the stability of the support bed board 4 is improved by the sliding limit block 3 inside the protective plate 5. At the same time, the fixing block 2 gradually releases the limit on the flip plate 6, causing the flip plate 6 to rotate. When the support bed board 4 rises to the highest point, the flip plate 6 is parallel to the support bed board 4, which makes it convenient for medical staff to place the examination instruments when examining elderly patients and improves the examination efficiency. Furthermore, when the patient's examination is completed, the cylinder 101 is activated to extend and reset the support bed board 4 downward. During the downward reset, the head foam pad 9 is limited by the cooperating column 10, causing the head foam pad 9 to rotate slowly and lift the patient's head while lying flat. Lifting the head helps improve blood circulation in the head and promotes blood supply to the brain, thereby improving the quality of sleep and rest. When the patient needs to use the toilet, the motor 201 is started to rotate. The rotation of the motor 201 drives the push block 17 to slide to the left through the lead screw 202. During the sliding process, the push block 17 contacts the flipping triangle block 16, thereby squeezing the flipping triangle block 16 to control the waist sponge pad 8 to swing to one side, thereby lifting the patient's upper body and adjusting the patient's sitting posture to facilitate the patient's use of the toilet. Furthermore, the rotation of the lead screw 202 drives the first lead screw 204 and the second lead screw 205 to rotate via the transmission belt 203. The rotation of the first lead screw 204 drives the transmission frame 206 to slide to the left on the surface of the first lead screw 204. The sliding of the transmission frame 206 drives the fixed shaft 208 and the sliding rod 207 to move synchronously. Before using the toilet, the plastic bag 15 is fixedly placed on the surface of the fixed shaft 208 and the sliding shaft 209. Then, the rotation of the first lead screw 204 delivers the plastic bag 15 to the area below the patient's buttocks, making it convenient to collect the excrement. Furthermore, the rotation of the second lead screw 205 controls the reciprocating sliding frame 301 to slide to the right. The reciprocating sliding frame 301 is located above the fixed shaft 208. When the reciprocating sliding frame 301 moves relative to the transmission frame 206, since the bottom surface of the reciprocating sliding frame 301 and the surface of the sliding shaft 209 are magnetically set, the sliding shaft 209 is attracted to the reciprocating sliding frame 301 under the magnetic action below the reciprocating sliding frame 301. When the reciprocating sliding frame 301 and the transmission frame 206 continue to move, the sliding shaft 209 is close to and slides with the reciprocating sliding frame 301, which can open the opening of the plastic bag 15 to the maximum and stretch the plastic bag 15 into a taut state, further receiving the excrement and further improving the excrement collection capacity. When the fixed shaft 208 slides below the reciprocating sliding frame 301, the fixed shaft 208 presses upward against the drive block 305, causing the drive block 305 to slide upward on the surface of the reciprocating sliding frame 301. As the drive block 305 slides upward, it drives the drive horizontal shaft 306 to move synchronously. One end of the drive horizontal shaft 306 controls one end of the transmission horizontal bar 307 to swing around the limiting fixed rod 308. The other end of the transmission horizontal bar 307 controls the pneumatic plate 310 to slide downward inside the pneumatic chamber 302 via the connecting transmission roller 309, thus moving the pneumatic chamber 302 downward. 2. The air inside is squeezed to the left side of the reciprocating sliding frame 301; at the same time, the drive horizontal shaft 306 drives the piston disc 312 to slide upward inside the piston cylinder 304 through the piston rod 311, compressing the air inside the piston cylinder 304 into the liquid bottle 303. The disinfectant liquid inside the liquid bottle 303 is discharged into the pneumatic chamber 302 through air compression, and then mixed with the air output from the pneumatic chamber 302 to form a mist for disinfection and sterilization under the patient's buttocks and around the support bed board 4, reducing the risk of bacterial infection for the patient. Two sets of this component are arranged in opposite directions inside the reciprocating sliding frame 301. When the plastic bag 15 moves continuously and is located below the reciprocating sliding frame 301, the fixed shaft 208 contacts the drive block 305 in the other set of components. The disinfectant output from the other set is discharged downward to disinfect the plastic bag 15 and can wet the inner surface of the plastic bag 15, so that the excrement can slide into the depth of the plastic bag 15, avoiding the leakage of excrement and causing serious impact on the on-site environment. When the reciprocating sliding frame 301 slides, the friction wheel 401 rotates after rubbing against the reciprocating sliding frame 301. The friction wheel 401 drives the bevel gear component 403 to rotate through the drive shaft 402, which in turn drives the moving disk 404 to rotate. A protrusion is provided on the surface of the moving disk 404, which slides inside the moving rod 405. When the moving disk 404 rotates, the moving rod 405 drives the vibration shaft 406 to slide back and forth through the protrusion. When the plastic bag 15 slides to the left, the vibration shaft 406 continuously beats and vibrates the bottom of the plastic bag 15 to prevent the inner surfaces of the plastic bag 15 from adhering to each other, which would prevent the sliding shaft 209 from opening it and thus affect the rapid collection of excrement. When the patient finishes using the toilet, the motor 201 reverses, and the lumbar sponge pad 8 gradually returns to a parallel state during the reset process of the push block 17. When the motor 201 reverses, the second lead screw 205 controls the reciprocating sliding frame 301 to reset to the left, and the first lead screw 204 controls the transmission frame 206 to move to the right to transport the excrement inside the plastic bag 15. When the sliding shaft 209 contacts the bottom of the reciprocating sliding frame 301, under the influence of magnetism, the sliding shaft 209 gradually contacts the fixed shaft 208. The top of the plastic bag 15 is moistened by the disinfectant and then mutually adsorbed by the compression of the sliding shaft 209 and the fixed shaft 208, thereby appropriately sealing the opening of the plastic bag 15, further improving the sealing of the excrement and avoiding the risk of bacterial infection. At the same time, the reciprocating vibration shaft 406 beats and vibrates the plastic bag 15 containing the excrement, which can collect the excrement, making it convenient for medical staff and patients' families to take it, speeding up the processing of excrement, avoiding air pollution, and enhancing the patient's recovery effect.
