[0002] The main function of the turning support device is to assist patients in turning over, reduce the labor intensity of nurses, and improve patient comfort and satisfaction. The design of the turning support device aims to solve the difficulties of patients during the turning process. By providing mechanical assistance or a specially designed support structure, it helps patients change their body positions more easily. Such devices usually have the following characteristics and functions: assisting in turning over, reducing the labor intensity of nurses, improving patient comfort, facilitating nurse operation, and enhancing patient satisfaction.

[0003] Currently, some patients need to undergo prone position treatment. However, during the long-term support process, pressure sores may occur at the positions where the patients are in contact in the prone position. Currently, there are also corresponding devices to assist in turning over, but the current turning devices have relatively single functions. After the patient's body is supported to a certain inclination angle, the patient still needs to exert force by himself or with the assistance of external medical staff to complete the turning over successfully, which is rather troublesome to operate. Therefore, a prone position support device with a turning function is needed to solve the above problems. Summary of the Invention

By setting the upper surface of the second T-shaped block as an inclined surface, when the upper surface of the second T-shaped block contacts the surface of the entry hole, the second T-shaped block is driven to descend and compress the second spring, and then enters the T-shaped groove and is reset by the second spring. At this time, the second T-shaped block and the first T-shaped block are in the T-shaped groove, jointly maintaining the stability of the movement of the bed board. When the first T-shaped block is inserted into the entry hole during the movement of the bed board, the upward sliding movement is kept stable.

[0016] By setting the limiting surface to be at the same height as the top surface of the guiding column, when the upper surface of the semi-circular plate is blocked by the limiting surface, the upper surface of the second T-shaped block is at the highest surface of the T-shaped groove. At this time, the lower surface of the first T-shaped block is just blocked and supported by the upper surface of the stopper, maintaining the stability of the removal of the bed board from the first lead screw and the guiding column. The micro-motor drives the worm to rotate, the rotation of the worm drives the worm wheel to rotate, and the worm wheel drives the second connecting shaft and the bed board to rotate, enabling the patient on the bed board to rotate 180 degrees for turning over. After turning over, the patient is received by the lower bed board, ensuring safety after turning over and making it convenient and labor-saving to turn over with the assistance of the device.

[0029] The flipping and disassembling mechanism 9 includes a headrest 901, a chest pillow 902, and a hip pillow 903 fixedly connected to the inner wall of the bed board 6. One side of the bed board 6 is fixedly connected with a first connecting shaft 910. One side of the first connecting shaft 910 is rotatably connected with a pair of semi-circular plates 908.

The opposite surfaces of the pair of semi-circular plates 908 are threadedly connected to the surface of the first lead screw 907. The inner walls of the pair of semi-circular plates 908 are threadedly connected with the same screw 909.

[0030] With the above structure, by setting the placement bed 4 to support the patient's body, by setting the catheter clamping plate 10 to clamp and position the medical catheter on the patient to keep it stable, by setting the L-shaped plate 2 to install and fix the forward and reverse reduction motor 3, by setting the guide post 5 to keep the placement bed 4 stable when sliding up, by setting the bed board 6, the width of the two bed boards 6 is one-third of the width of the placement bed 4, and the shoulder width of a normal patient is one-third of the placement bed 4 to avoid affecting the first aid of the patient, by setting the headrest 901, the chest pillow 902, and the hip pillow 903 to protect the patient's head, chest, and buttocks respectively to keep them comfortable, by setting the first connecting shaft 910 to maintain the connection and support with the bed board 6 and at the same time maintain the stable installation with the pair of semi-circular plates 908, by setting the pair of semi-circular plates 908 and clamping and fixing them with the screw 909. When the first lead screw 907 rotates, it drives the movement of the pair of semi-circular plates 908, so that the other side of the bed board 6 slides along the inside of the guide post 5 to maintain balance and stability.

[0031] As a preferred implementation manner in this embodiment, the other side of the bed board 6 is fixedly connected with a second connecting shaft 930. One end of the second connecting shaft 930 is rotatably connected with a sleeve 917. The inner wall of the sleeve 917 is fixedly connected with a fixing block 919. The inner wall of the sleeve 917 is rotatably connected with a third lead screw 918. One end of the third lead screw 918 is rotatably connected with one side of the fixing block 919.

[0032] By setting the second connecting shaft 930, the connection and support for the sleeve 917 are realized. By setting the third lead screw 918, when the operator rotates the third lead screw 918, the third lead screw 918 drives the fitting arc plate 920 to slide. By setting the fixing block 919, when the fitting arc plate 920 approaches the surface of the guide post 5, the fixing block 919 will not contact the surface of the guide post 5, thus realizing spatial avoidance.

[0033] In this embodiment, a fitting arc plate 920 is threadedly connected to the surface of the third lead screw 918. A first T-shaped block 921 is fixedly connected to the surface of the fitting arc plate 920. A second spring 929 is slidably connected to one side of the first T-shaped block 921. The top end of the second spring 929 is fixedly connected to a second T-shaped block 928. The upper surface of the second T-shaped block 928 is arranged as an inclined surface. One side of the second T-shaped block 928 is slidably connected to the surface of the first T-shaped block 921.

[0034] By setting the fitting arc plate 920, the first T-shaped block 921 is driven to insert into the access hole 927. By setting the second spring 929, the second T-shaped block 928 is driven to move back to its original position. By setting the upper surface of the second T-shaped block 928 as an inclined surface, when the upper surface of the second T-shaped block 928 contacts the surface of the access hole 927, the second T-shaped block 928 is driven to descend and compress the second spring 929, and then enters the T-shaped groove 911 and is reset by the second spring 929. At this time, the second T-shaped block 928 and the first T-shaped block 921 are in the T-shaped groove 911, jointly maintaining the stable movement of the bed board 6.

[0035] In this embodiment, a support plate 922 is fixedly connected to one side of the sleeve 917. A micro motor 923 is fixedly connected to the upper surface of the support plate 922. A protective cylinder 924 is fixedly connected to one side of the bed board 6. The output end of the micro motor 923 penetrates through the inner wall of the protective cylinder 924 and is fixedly connected to a worm 925. A worm gear 926 is fixedly connected to the surface of the second connecting shaft 930. The worm 925 meshes with the worm gear 926.

[0036] By setting the support plate 922, the micro motor 923 is installed and fixed. By setting the worm 925, the rotation of the worm 925 drives the rotation of the worm gear 926. The worm gear 926 drives the second connecting shaft 930 and the bed board 6 to rotate, enabling the patient on the bed board 6 to rotate and turn over.

[0037] As a preferred implementation manner in this embodiment, a T-shaped groove 911 is opened on the upper surface of the guide post 5. An access hole 927 is fixedly connected to the inner wall of the T-shaped groove 911. A relief groove 913 is opened on the inner wall of the T-shaped groove 911. A first spring 912 is fixedly connected to the inner wall of the relief groove 913. One end of the first spring 912 is fixedly connected to a stop block 914. The surface of the stop block 914 is slidably connected to the inner wall of the relief groove 913.

[0038] By providing the T-shaped groove 911, the movement directions of the second T-shaped block 928 and the first T-shaped block 921 are limited to maintain stability. By providing the access hole 927, when installing, the first T-shaped block 921 and the second T-shaped block 928 can be inserted into the access hole 927. By providing the recessed groove 913, space is given for installing the first spring 912. By providing the stop block 914, when the first T-shaped block 921 is located above the stop block 914, the lower surface of the stop block 914 is supported to maintain stable positioning.

[0039] As a preferred implementation manner in this embodiment, a return plate 931 is fixedly connected to the upper surface of the bed board 6. A second lead screw 915 is threadedly connected to the inner wall of the return plate 931. A T-shaped shaft 916 is slidably connected to the inner wall of the return plate 931. The bottom end of the second lead screw 915 is rotatably connected to the upper surface of the T-shaped shaft 916.

[0040] By providing the return plate 931, the installation stability of the second lead screw 915 is maintained. By providing the second lead screw 915, rotating the second lead screw 915 drives the T-shaped shaft 916 to slide in the return plate 931 to adjust its height. By providing the T-shaped shaft 916, the pressing and positioning of the through hole 905 are realized.

[0041] As a preferred implementation manner in this embodiment, an elastic band 904 is fixedly connected to the upper surface of the bed board 6. A plurality of through holes 905 are provided on the upper surface of the elastic band 904. A positioning groove 906 is provided on the surface of the placement bed 4. A convex plate 932 is fixedly connected to the lower surface of the placement bed 4. The convex plate 932 is adapted to the inner wall of the positioning groove 906.

[0042] By providing the elastic band 904, a plurality of elastic bands 904 are evenly and equidistantly distributed, which are used to fix various parts of the patient's head, body, and legs to maintain the safety and stability of the patient during turning over. By providing the positioning groove 906, it is convenient for quickly positioning the bed board 6 that has been turned over and disassembled to be reinstalled on the placement bed 4. At the same time, it is convenient to push the bed board 6 placed in the positioning groove 906 to its corresponding position after one bed board 6 is raised to receive the turned-over patient.

[0043] As a preferred implementation manner in this embodiment, one side of the L-shaped plate 2 is provided as a limiting surface 201. The topmost height of the guide post 5 is the same as the height of the limiting surface 201.

[0044] By providing the limiting surface 201, the height of the limiting surface 201 is the same as the topmost surface of the guide post 5. When the upper surface of the semi-circular plate 908 is blocked by the limiting surface 201, the upper surface of the second T-shaped block 928 is located at the highest surface of the T-shaped groove 911. At this time, the lower surface of the first T-shaped block 921 is just blocked and supported by the upper surface of the stop block 914, maintaining the stability of the bed board 6 being disassembled from the first lead screw 907 and the guide post 5.

[0045] The working principle of the present invention is as follows: For a prone position support device with a turning function, when in use, first, after the patient lies on the bed board 6, their head, body, and legs are limited and fixed by multiple elastic bands 904. Then, the medical staff rotates the second lead screw 915 to drive the T-shaped shaft 916 to descend, so that the T-shaped shaft 916 is inserted into the corresponding through hole 905 to maintain the stable limitation of the elastic band 904 on the patient's body. Next, the forward and reverse reduction motor 3 is started, and the output end of the forward and reverse reduction motor 3 drives the first lead screw 907 to rotate. The rotation of the first lead screw 907 drives a pair of semi-circular plates 908 to move. At this time, since the second T-shaped block 928 and the first T-shaped block 921 are located in the T-shaped groove 911, the sliding stability during the ascent of the bed board 6 can be maintained. When the bed board 6 ascends, the medical staff pushes the bed board 6 located in the positioning groove 906 inward to make it correspond to the position of the ascending bed board 6. During the ascent of the bed board 6, the micro motor 923 is started, and the output end of the micro motor 923 drives the worm 925 to rotate. The worm 925 drives the worm gear 926 to rotate. The rotation of the worm gear 926 drives the second connecting shaft 930 to rotate. The rotation of the second connecting shaft 930 drives the bed board 6 to rotate, so that the patient rotates 180 degrees. Then, through multiple elastic bands 904, the patient is kept safe and stable. Next, the forward and reverse reduction motor 3 is started to reverse the first lead screw 907, driving the bed board 6 to descend, so that the patient's face faces the headrest 901 position of the corresponding bed board 6 below. When the patient contacts the lower bed board 6, the elastic bands 904 are loosened, and the forward and reverse reduction motor 3 is started again to drive the reversed bed board 6 to ascend. When the upper surface of the semi-circular plate 908 is blocked by the limiting surface 201, the upper surface of the second T-shaped block 928 is located at the highest surface of the T-shaped groove 911. At this time, the lower surface of the first T-shaped block 921 is just blocked and supported by the upper surface of the stopper 914. The screw 909 is rotated to release the contact limit between the semi-circular plate 908 and the first lead screw 907. The first T-shaped block 921 connected to the other side bed board 6 is in the T-shaped groove 911 to maintain the stability of disassembly. Then, the bed board 6 is pushed upward to remove it and re-placed in the positioning groove 906 to prepare for the next reverse movement. The bed board 6 on which the patient lies on their side is connected to the first lead screw 907 through the semi-circular plate 908 and the screw 909. At this time, during the process of the second T-shaped block 928 being inserted into the insertion hole 927, it drives the second T-shaped block 928 to descend and compress the second spring 929, and then reset. The second T-shaped block 928 and the first T-shaped block 921 are re-locked in the T-shaped groove 911 to maintain the stability during upward movement, facilitating the next rotation of the patient's body. With the above structure, the patient's body can be automatically turned 180 degrees, making it convenient and labor-saving to turn the patient's body with the assistance of the device.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
