[0038] like Figures 1 to 3As shown, the body position turning device of the present invention includes a support structure 6 and a fixing device for fixing a human body 7. The fixing device is rotatably mounted on the support structure 6. The fixing device includes a front supporting mechanism for supporting the front side of the human body 7 and a rear supporting mechanism for supporting the rear side of the human body 7. A fixing space for accommodating the human body 7 is formed between the rear supporting mechanism and the front supporting mechanism. The body position turning device also includes an operating mechanism or a driving device 1 for driving the fixing device to turn so that the human body switches between a supine position and a prone position. The entire human body is fixed by the cooperation of the front supporting mechanism and the rear supporting mechanism, so that the entire human body is safer and more reliable in the process of turning and switching the body position.

[0039] like Figures 1 to 3 As shown, in an exemplary embodiment, the force point of the operating mechanism can be on the front supporting mechanism or the rear supporting mechanism, that is, the operating mechanism can directly apply force to the front supporting mechanism or the rear supporting mechanism to flip the assembled retaining device and the human body as a whole.

[0040] like Figures 1 to 3 As shown, in an exemplary embodiment, the operating mechanism is a manual force applying mechanism or an automatic force applying mechanism.

[0041] like Figures 1 to 5 As shown, in an exemplary embodiment, the rotation axis of the retaining device is along the length direction of the human body 7, and the two ends of the retaining device are respectively connected to the support structure 6 through the front flip transmission mechanism 4 and the rear flip transmission mechanism 5. The driving device 1 is connected to the front flip transmission mechanism 4 or the rear flip transmission mechanism 5, thereby driving the retaining device to rotate so that the body position of the human body is maintained in any position between the supine position and the prone position, including the supine position and the prone position.

[0042] like Figures 1 to 4As shown, in an exemplary embodiment, the front-end flip transmission mechanism 4 is connected to an end of the retaining device close to the human head. The front-end flip transmission mechanism 4 includes a first bearing seat 41 mounted on the support structure 6 and a first rotating shaft 42 mounted in the first bearing seat 41.

The first rotating shaft 42 is provided with a channel 421 for pipelines to pass through along its axial direction. The channel 421 can be used for pipelines such as oxygen tubes and cables to pass through, which not only makes the pipeline layout neat and stable, but also avoids interference between the pipeline and the front-end flip transmission mechanism during the flipping process of the human body. In this embodiment, the second end of the first rotating shaft 42 is a square column, and the second end of the first rotating shaft 42 is provided with a threaded hole. The square column is assembled and fixed to the connecting frame 23 of the fixing device to prevent rotation. The second end of the square column passes through one side of the connecting frame 23 and is locked and connected to the first rotating shaft end cover 46 located on the other side of the connecting frame 23 through a locking bolt. The first rotating shaft end cover 46 is provided with a through hole for the pipeline to pass through. This structural design avoids the need to set threaded holes along the radial direction of the first rotating shaft, which is beneficial to ensuring the strength of the first rotating shaft.

The second shaft 52 is connected to the connecting frame 23 of the fixing device and rotates synchronously. In this embodiment, the second end of the second shaft 52 is a square column, and the second end side wall and the second end end of the second shaft 52 are both provided with threaded holes. The square column is assembled and fixed to the connecting frame 23 of the fixing device. The second end of the square column passes through one side of the connecting frame 23 and is locked and connected to the second shaft end cover 56 located on the other side of the connecting frame 23 through a locking bolt. The threaded hole on the second end side wall of the second shaft is also installed with a locking bolt, and is locked with the connecting frame through the locking bolt. The structural design makes the connection between the second shaft 52 and the connecting frame 23 more firm and stable.

[0045] like Figures 1 to 3 , Figure 5 As shown, in an exemplary embodiment, the rear end flip transmission mechanism 5 also includes a second bearing cover 54 connected to the second bearing seat 51, and the inner side of the second bearing cover 54 is circumferentially provided with a second limiting groove 542, and the first end outer wall of the second rotating shaft 52 is installed with a second limiting pin 55 for cooperating with the second limiting groove 542 to limit the circumferential rotation range of the second rotating shaft 52, so that the retaining device rotates within the circumferential range set by the second rotating shaft, ensuring the safety of the position adjustment. The first end of the second rotating shaft 52 passes through the second bearing cover and is connected to the driving device 1 through the key 57, and the driving device 1 drives the second rotating shaft 52 and the connecting frame 23 to rotate together. Among them, the second bearing cover 54 is provided with a second through hole 541 for the first end of the second rotating shaft to pass through, and the second limiting groove 542 is arranged on the inner wall of the second through hole 541. In this embodiment, the second limiting groove 542 can be arranged along the circumference of the inner wall of the second through hole 541, and half of the circumference, so that the human body can be turned over at 0 to 180 degrees to achieve switching from supine position to prone position.

Among them, the rear support frame 31 includes two support rods of a rod-shaped structure, the two support rods are arranged in parallel, and the two support rods are connected by a slide 32. A plurality of slides 32 are distributed at intervals along the length direction of the human body. The slides 32 can slide along the support rods and be locked or unlocked by a locking member 33. The locking member 33 can be a bolt. One end of the bolt passes through the threaded hole on the slide and then presses the support rod to achieve locking. A clamping assembly for pressing different parts of the human body is installed on the slide. The pressing component includes a pressing head cover 35 for pressing the human head. The pressing head cover 35 is annular and has a certain thickness. The pressing head cover can be made of sponge, plastic, silicone and other materials with a certain deformation ability, so that when the pressing head cover presses the human head, the side of the pressing head cover in contact with the human head and neck is depressed by force, thereby protecting the human head and neck and preventing the human head and neck from shaking; the pressing component also includes a pressing plate, which can be used to press the back, buttocks, legs and other parts of the human body. The side of the pressing plate 34 in contact with the human body can be a curved surface, which is conducive to improving the fit when in contact with the human body, making the human body more firmly fixed.

Connecting frames 23 are provided on both ends of the front support plate 21, and the connecting frames 23 are used to connect with the rear support mechanism, the front flip transmission mechanism 4 and the rear flip transmission mechanism 5. In this embodiment, the side of the front support plate 21 that contacts the human body can be a curved surface structure, which is conducive to the human body fitting therewith and improving the comfort. The front support plate 21 can be made of a material with a certain deformation ability such as sponge, plastic, memory foam, etc., so that when the human body is placed on the front support plate 21 and clamped with the rear support mechanism, the front support plate 21 can be recessed into a recessed cavity matching the human body to prevent the human body from sliding, thereby improving the comfort and safety performance.

[0049] like Figures 1 to 6As shown, in an exemplary embodiment, a mounting hole 231 is provided on the connecting frame 23, and a plurality of first locking holes 232 distributed along the depth direction of the mounting hole 231 are provided on the side wall of the mounting hole 231, and a connecting rod 311 corresponding to the mounting hole 231 is provided on the rear support frame 31, and a second locking hole 312 is provided on the connecting rod 311, and the connecting rod 311 extends into the mounting hole 231, and the front support mechanism is locked and connected with the rear support mechanism through the elastic pin 24 passing through the first locking hole 232 and the second locking hole 312.

For example, when the power input mechanism 12 is a handle, amplifying the input torque by the reducer 11 is conducive to making manual operation more labor-saving; when the power input mechanism 12 is a motor, reducing the input torque by the reducer 11 is conducive to smoother flipping of the fixing device and improved flipping safety performance.

[0054] In an exemplary embodiment, the driving device may also be directly connected to the retaining device so as to be able to drive the retaining device to flip.

[0055] like Figures 1 to 3 As shown, in an exemplary embodiment, the support structure 6 can be a bed frame, which is a square frame, and the retaining device is rotatably connected to the bed frame and suspended on the inner side of the bed frame, which not only ensures the stability of the structure, but also avoids the retaining device from interfering with the bed frame during the flipping process, and has a simple structure, convenient manufacturing, and low cost.
