Description

Technical Field

[0001] This utility model relates to the field of patient care technology, specifically to an intelligent patient transfer and turning device. Background Technology

[0002] Most seriously ill patients lose their ability to move, so transporting obese seriously ill patients is more difficult. At the same time, during the treatment of most seriously ill patients, in order to prevent bedsores, users need to turn the patients over and wipe them frequently. However, most transport beds also have turning-over assist devices, but most transport beds cannot fix the limbs of the patient after turning over, so the patient may return to a supine position as the turning board in the transport bed resets. At the same time, because the patient's position cannot be fixed after turning over, the user needs to support the patient while wiping the patient's back, which increases the difficulty of the user caring for the patient.

In addition to the basic load-bearing function, the main bed frame 1 has a 5mm radius rounded chamfer at its edge, which effectively prevents users from being injured by collisions during daily activities. The first mounting block 301 is fixedly installed on the bottom outer surface of the main bed frame 1. Two sets of the first mounting blocks 301 are symmetrically arranged, and there are two first mounting blocks 301 in one set. The positioning frame 3 is rotatably connected to the first mounting block 301. The number of mounting blocks and positioning frames 3 are the same and correspond one-to-one. Wear-resistant pads are provided between the inside of the first mounting block 301 and the positioning frame 3 to reduce noise. A connecting rod 302 is fixedly connected between the two sets of positioning frames 3. The connecting rod 302 can realize the synchronous linkage of the two sets of positioning frames 3. The second self-locking servo motor 303 is fixedly connected to the bottom of the main bed frame 1. The second self-locking servo motor 303 is equipped with a metal protective shell, and the protective shell has heat dissipation holes to dissipate the heat generated by the motor during operation. The output end of the second self-locking servo motor 303 is fixedly connected to the outer surface of the positioning frame 3. The second self-locking servo motor 303 can drive the positioning frame 3 to rotate. The movable rod 304 is slidably connected inside the positioning frame 3. To prevent the movable rod 304 from completely coming out of the positioning frame 3, a stop is provided at the end of the movable rod 304 near the lead screw 305. The lead screw 305 passes through the positioning frame 3 and is internally threaded to the moving rod 304. The lead screw 305 can drive the moving rod 304 to move. The fixed hook and loop fastener 306 is fixedly connected to the end of the moving rod 304. The fixed hook and loop fastener 306 is provided with a needle side and a rough side. The fixed hook and loop fastener 306 is used to fix the patient's body.

[0018] A reinforcing frame 101 is fixedly connected to the bottom of the main bed frame 1. The part where the reinforcing frame 101 is connected to the main bed frame 1 is fixed by welding. Lockable casters 102 are symmetrically installed at the bottom of the reinforcing frame 101. The lockable casters 102 can be locked by the user according to the user's requirements.

[0019] The main bed frame 1 has a sliding connection to a transfer plate 2, which is used to transfer patients, making it easier for users to transfer patients. The transfer plate 2 has a rotating connection to a turning plate 201, which can assist patients in turning over. The turning plate 201 has a slot 202 inside, and the bottom of the turning plate 201 is supported by the transfer plate 2, which makes the turning plate 201 have a large load-bearing capacity. The slot 202 passes through the turning plate 201 and the transfer plate 2.

[0020] A connecting frame 207 is provided at the center line of the slot 202. The connecting frame 207 is used to install and fix two sets of rotating plates 203. The two ends of the connecting frame 207 are respectively rotatably connected to the rotating plates 203. The rotating plates 203 have a sliding groove 204 inside.

[0021] A hydraulic cylinder 206 is fixedly connected to the top of the reinforcement frame 101. The output end of the hydraulic cylinder 206 passes through the main bed frame 1 and its end face is rotatably connected to the slider 205. When the hydraulic cylinder 206 is started, it will drive the rotating plate 203 to rotate, thereby achieving the purpose of turning the patient over.

[0022] Toothed plates 208 are fixedly connected to the bottom of both ends of the transfer plate 2. Transfer gears 209 are respectively set at the bottom of the two sets of toothed plates 208. The rotation of the transfer gears 209 will drive the toothed plates 208 to move, thereby driving the transfer plate 2 to move, so as to achieve the purpose of transferring the patient. A connecting rod 214 is fixedly connected between the two sets of transfer gears 209. The connecting rod 214 is rotatably connected to the bottom of the main bed frame 1. The connecting rod 214 can drive the two sets of transfer gears 209 to rotate simultaneously.

[0023] A first gear 210 is fixedly connected to the surface of the connecting rod 214. A second gear 211 is provided below the first gear 210. Rotation of the first gear 210 will drive the second gear 211 to rotate. Rotation of the second gear 211 will drive the two sets of transfer gears 209 to rotate together. The surfaces of the first gear 210, the second gear 211 and the transfer gears 209 are all wrapped and protected, and the wrapping and protecting mechanism is fixed to the main bed frame 1.

[0024] A fixing frame 213 is fixedly connected to the bottom of the main bed frame 1. The fixing frame 213 is fixed to the main bed frame 1 by bolts.

[0025] The main bed frame 1 is fixedly connected to two sides of a second mounting block 401. The side handle bracket 4 is rotatably connected inside the second mounting block 401. The fixing bolt 402 is rotatably connected inside the second mounting block 401. The tail end of the fixing bolt 402 is threaded into the inside of the side handle bracket 4. Rotating the fixing bolt 402 reduces the pressure between the side handle bracket 4 and the two sides of the second mounting block 401, allowing the side handle bracket 4 to rotate.

[0026] This utility model provides an intelligent patient transfer and turning device, the specific working principle of which is as follows: When transferring a patient, the user first pushes the device to the patient's bedside and adjusts the height of the bed so that the top of the bed is flush with the bottom of the transfer plate 2. Then, the user rotates the fixing bolt 402 near the patient's bedside to reduce the pressure on both sides of the side handle 4 and the second mounting block 401, thereby allowing the side handle 4 to rotate. After rotating the side handle 4, the user starts the first self-locking servo motor 212 to drive the first gear 210. The rotation of the first gear 210 will drive the second gear 211 to rotate. The rotation of the second gear 211 will drive the two sets of transfer gears 209 to rotate together. The rotation of the transfer gears 209 will drive the toothed plate 208 to move, thereby driving the transfer plate 2 to move, so that the transfer plate 2 passes under the patient's body. The user then drives the first self-locking servo motor 212 to rotate in the opposite direction, so that the transfer plate 2 is reset and the transfer is completed. After that, the user rotates the side handle 4 so that the inner side of the side handle 4 is in close contact with the transfer plate 2. Finally, the user rotates the fixing bolt 402 to fix the position of the side handle 4. When turning the patient over, the user first activates the hydraulic cylinder 206 to move it upward. The upward movement of the hydraulic cylinder 206 will drive the slider 205 to move upward, which will further drive the rotating plate 203 to rotate. The top of the rotating plate 203 is in close contact with the bottom of the turning plate 201. Therefore, the rotation of the rotating plate 203 will drive the turning plate 201 to rotate, thereby achieving the effect of turning the patient over. Then, the user activates the second self-locking servo motor 303 on one side to drive the positioning frame 3 on one side to rotate, which in turn drives the connecting rod 302 to rotate, thereby causing the positioning frame 3 on the other side to rotate. Then, the user rotates the lead screw 305 to adjust the moving rod 304 to rotate until the end of the moving rod 304 is in contact with the patient's body. Then, the user passes a set of fixing hook and loop fasteners 306 through the patient's body and attaches them to another set of fixing hook and loop fasteners 306 to fix the patient's body. Then, the user activates the hydraulic cylinder 206 to reset the position of the turning plate 201.
