DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-7 , an automatic turning medical nursing bed device, comprising a bed board 1, a foldable mattress 2 is arranged on the top of the bed board 1, two railings 3 are fixedly installed on the top of the bed board 1, and an automatic turning mechanism 4 and a temperature adjustment mechanism 5 are arranged outside the bed board 1;

[0031] The temperature regulating mechanism 5 comprises a temperature control box 501, a water storage tank 502, a delivery pump 503, a water heating and refrigeration box 504, an air cooling fan 505, an S-shaped coil 506, an electric heating ring 507, a fan cover 508, a hot air guide fan 509, a hot air pipe 510, a universal pipe joint 511, an air supply hose 512, a clamping fixture 513, a fixing plate 514, an air supply fan 515, a heat conduction cavity 516, a heat conduction plate 517 and a serpentine coil 518. The temperature control box 501 is fixedly installed at the bottom of the bed board 1, and the water storage tank 502, the delivery pump 503 and the water heating and refrigeration box 504 are fixedly installed inside the temperature control box 501. The air cooling fan 505 and the S-shaped coil 506 are fixedly installed inside the water heating and refrigeration box 504, and the S-shaped coil 506 is fixedly installed outside. The heat ring 507 and the water heating refrigeration box 504 are fixedly installed with two fan covers 508 on the top, and a hot air guide fan 509 is fixedly installed inside each fan cover 508. A hot air duct 510 is fixedly installed on the top of the two fan covers 508. A universal pipe joint 511 is installed at one end of the hot air duct 510 away from the fan cover 508, and an air supply hose 512 is installed on the outside of the universal pipe joint 511. A clamping fixture 513 is installed on the outside of the railing 3, and a fixing plate 514 is fixedly installed on the outside of the clamping fixture 513, and an air supply fan 515 is fixedly installed on the inside of the fixing plate 514. A heat conduction cavity 516 is opened inside the foldable mattress 2, and a heat conduction plate 517 is fixedly installed on the top of the foldable mattress 2, and a serpentine coil 518 is fixedly installed inside the heat conduction cavity 516.

[0032] Furthermore, the automatic turning mechanism 4 includes a sliding groove 401, a first hinge 402, a support rod 403, a drive box 404, a threaded rod 405, a transmission wheel 406, a transmission belt 407, a drive box 408 and a drive motor 409. Two sliding grooves 401 are opened inside the bed board 1, and two first hinges 402 are fixedly installed on the right bottom of the foldable mattress 2. The bottoms of the two first hinges 402 are hinged with support rods 403. The bottom of the bed board 1 is fixedly installed with a drive box 404 and a drive box 408. The inside of the drive box 404 is rotatably connected to the threaded rod 405, the outside of the threaded rod 405 is fixedly installed with a transmission wheel 406, the outside of the transmission wheel 406 is movably installed with a transmission belt 407, and the inside of the drive box 408 is fixedly installed with a drive motor 409.

[0033] Specifically, the core components of the temperature regulating mechanism 5 are the air-cooling fan 505 and the air-cooling fan 505 inside the water-heating refrigeration box 504. When heating is required, the electric heating coil 507 is energized to generate heat to heat the water in the S-shaped coil 506. At this time, the air-cooling fan 505 stops working, and the heated water is extracted from the water storage tank 502 through the first delivery pipe under the action of the delivery pump 503, and then enters the S-shaped coil 506 through the second delivery pipe, and then enters the serpentine coil 518 inside the foldable mattress 2 from the right side of the S-shaped coil 506 through the bottom of the bed board 1. The serpentine coil 518 is in close contact with the heat conducting plate 517, and the heat is transferred to the patient through the heat conducting plate 517. At the same time, the hot air guide fan 509 blows the hot air in the water-heating refrigeration box 504 through the hot air pipe 510, the universal pipe joint 511 and the air supply hose 512, and blows it to the top of the foldable mattress 2 under the action of the air supply fan 515 to achieve all-round heating.

[0034] Specifically, when cooling is needed, the air-cooling fan 505 is started and the electric heating coil 507 stops working. The air-cooling fan 505 allows air to flow through the S-shaped coil 506, taking away the heat of the water in the coil to achieve cooling. The cooled water is also circulated in the entire system driven by the delivery pump 503, so that the foldable mattress 2 is cooled. The return pipe on the left side of the water tank 502 can allow the water in the serpentine coil 518 to flow back to the water tank 502 to ensure water circulation.

[0035] Specifically, the clamping fixture 513 is fixed to the railing 3 by a screw and two clamping fixing rings, so as to fix the fixing plate 514 and the air supply fan 515 in a suitable position, and the clamping fixture 513 can slide back and forth on the railing 3, so that the medical staff can adjust the appropriate air supply position, and the clamping fixture 513, the fixing plate 514 and the air supply fan 515 can be disassembled, so that the medical staff can freely choose whether to use them and also facilitate their maintenance.

[0036] Specifically, the automatic turning mechanism 4 provides a convenient turning function for the patient. After the driving motor 409 in the driving box 408 is started, the transmission wheel 406 at its output end drives the threaded rod 405 in the driving box 404 to rotate through the transmission belt 407. The second hinge connected to the external thread of the threaded rod 405 will move left and right along the limiting slide groove when the threaded rod 405 rotates. Since the two support rods 403 are fixedly connected by the connecting rod, and the second hinge is connected to the center position of the connecting rod, when the second hinge moves to the right, it will push the support rod 403 to lift up, and the two first hinges 402 at the bottom right side of the foldable mattress 2 are hinged to the support rod 403. The lifting of the support rod 403 will cause the right side of the foldable mattress 2 to rise, thereby enabling the patient to turn over to the left.

[0037] Specifically, when the driving motor 409 is reversed, the right side of the foldable mattress 2 can be lowered, so that the patient can turn over to the right side. During the operation, the nursing staff first ensures that the patient is in a safe and comfortable state, and then starts the driving motor 409 to perform the turning operation in the corresponding direction according to the patient's needs. The through hole at the bottom of the driving box 404 is used to arrange components such as the transmission belt 407 to ensure the smoothness of the transmission. The setting of the sliding groove 401 provides a certain guiding effect for the movement of the support rod 403, making the turning process more stable and reliable. Through the automatic turning mechanism 4, the patient can easily turn over without the help of others, which reduces the workload of the nursing staff and also improves the comfort and autonomy of the patient.

[0038] Specifically, the design of the foldable mattress 2 has many advantages. The internal heat-conducting cavity 516 accommodates the serpentine coil 518. The serpentine coil 518 is distributed in a serpentine shape to increase the contact area with the medium in the heat-conducting cavity 516 and improve the heat exchange efficiency. The heat-conducting plate 517 is fixed on the top of the foldable mattress 2 and is tightly connected to the serpentine coil 518. It can quickly and evenly transfer heat or cold to the patient's body. When cooperating with the temperature adjustment mechanism 5, when water flows in the serpentine coil 518, the heat or cold quickly spreads to the entire heat-conducting plate 517 and is then transferred to the patient through the heat-conducting plate 517.

[0039] In summary, the automatic turning medical nursing bed device utilizes the electric heating coil 507 and the air-cooling fan 505 in the water-heating refrigeration box 504 to accurately heat or cool the water. Subsequently, through the synergistic effect of the serpentine coil 518 and the heat conducting plate 517, the appropriate temperature is stably transmitted to the patient via the foldable mattress 2. In this way, the temperature can be automatically adjusted according to the actual needs of the patient and the dynamic changes of the room temperature, effectively avoiding the patient's unpleasant feelings caused by the discomfort of cold and heat, greatly improving the patient's comfort, and creating a more pleasant rehabilitation environment for the patient.

[0040] In addition, the automatic turning over medical nursing bed device is equipped with an efficient air supply structure consisting of a hot air guide fan 509 and an air supply fan 515, which can evenly distribute the heated or cooled air in the water heating refrigeration box 504 to the space above the foldable mattress 2. In this way, an all-round and balanced heating or cooling effect on the patient's body is achieved, further ensuring the temperature suitability of the patient during the use of the nursing bed, effectively improving the patient's experience of use, and solving the problem that the comfort of the prior art still needs to be improved. The patient may feel cold or hot due to changes in room temperature or different personal physiques, especially when sleeping at night. This discomfort is particularly obvious. Long-term cold and heat discomfort will not only affect the patient's rest quality, but may also cause colds or other health problems.
