[0027] 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.

[0028] like Figure 1 and Figure 2 As shown, a prone position ventilation bed comprises a bed frame 1, a lifting assembly 2, a turning assembly 3, and a bed board assembly 4 which are arranged in an upper and lower manner in a mirror image of each other;

[0029] The lifting assembly 2 and the turning assembly 3 are both fixedly mounted on the bed frame 1, and the bed board assembly 4 is overlapped on the lifting assembly 2;

[0030] The lifting assembly 2 is used to drive the bed board assembly 4 to perform lifting actions;

[0031] The flip assembly 3 is used to flip the mirror-arranged bed board assembly 4 as a whole.

[0032] During use, when a patient lying in a supine position on the bed board assembly 4 needs to be turned into a prone position, the lifting assembly 2 drives the upper bed board assembly 4 to move downward to clamp the patient on the lower bed board assembly 4. After clamping, the turning assembly 3 turns the mirror-arranged bed board assembly 4 as a whole, so that the patient lying in a supine position on the bed board assembly 4 needs to be turned into a prone position. In this way, the patient in a supine position can be turned into a prone position, and similarly, the patient in a prone position can also be turned into a supine position; thereafter, the upper bed board assembly 4 rises to form a certain interval between the bed board assemblies 4, which is convenient for medical staff to observe or operate on the patient on the lower bed board assembly 4.

[0033] In this embodiment, the bed board assembly 4 includes a bed board frame 41 and a lap plate 42, wherein the lap plate 42 is matched with the cavity of the bed board frame 41, and the lap plate 42 and the bed board frame 41 are connected in an up-and-down sliding manner;

[0034] A driving frame 43 is provided at the end corner of the lower end surface of the lap plate 42, and a driving rod 44 corresponding to the driving frame 43 is provided on the lower end surface of the bed frame 41, wherein the driving rod 44 is rotatably connected to the bed frame 41, and an external thread is provided on the driving rod 44, wherein the driving frame 43 and the corresponding driving rod 44 are connected by threaded matching;

[0035] A coaxial external gear 45 is fixedly mounted on the driving rod 44, wherein the external gears 45 on different driving rods 44 are connected via a synchronous belt 46, and any driving rod 44 is fixedly connected to the output end of the first motor 47, wherein the first motor 47 is fixedly mounted on the lower end surface of the bed board frame 41.

[0036] When in use, the patient lies supinely or prone on the lap board 42 of the bed board assembly 4. When the patient needs to change the supine position and the prone position, the first motors 47 on the upper and lower bed board assemblies 4 both work, and the working first motors 47 drive the driving rod 44 to rotate. The rotating driving rod 44 uses the external gear 45 and the synchronous belt 46 to drive all the driving rods 44 to rotate synchronously. The synchronously rotating driving rod 44 uses the driving frame 43 to indirectly drive the lap board 42, so that a concave receiving groove is formed between the lap board 42 and the bed board frame 41, and the patient is in the receiving groove.

[0037] The lifting assembly 2 drives the upper bed board assembly 4 to move downward until the bed board frame 41 of the upper bed board assembly 4 is in contact with the bed board frame 41 of the lower bed board assembly 4. At this time, the patient is in the storage slot. At this time, the flipping assembly 3 flips the mirror-arranged bed board assembly 4 as a whole, so that the patient can switch between a supine position and a prone position.

[0038] The present invention utilizes the patient in the storage slot to flip over. Compared with directly clamping the patient to flip over, firstly, it avoids the patient from being separated from the bed board assembly 4 during the flipping process. Secondly, during the flipping process, there is no need to clamp the patient's body, avoiding the possibility of the patient being pinched due to excessive clamping force between the bed board assemblies 4, while also improving the patient's comfort.

[0039] In this embodiment, a through detection hole 421 is provided on the overlapping plate 42 ; when in use, when the patient is in a prone position, the patient's face can be observed conveniently through the detection hole 421 .

[0040] In the specific implementation process, the bed board assembly 4 with the patient on the bottom can be selected to be raised to a certain height by using the lifting assembly 2, so that the medical staff can observe the face of the patient in the prone position from below.

[0041] Alternatively, a detector 422 is provided directly below the detection hole 421 on the lower bed board assembly 4, and the face of the patient in the prone position is observed through the detector 422. The detector 422 is installed on the bed frame 1, wherein the detector 422 can be a camera.

[0042] In this embodiment, four lifting assemblies 2 are provided, wherein the four lifting assemblies 2 are independently distributed at the end corners of the bed board frame 41 of the bed board assembly 4;

[0043] like Figure 3 As shown, the lifting assembly 2 includes a second motor 21, a vertical driving rod 22, a vertical guide rod 23, a mounting seat 24, a third motor 25 and a rotating frame 26, wherein the output end of the second motor 21 is fixedly connected to the vertical driving rod 22, the vertical driving rod 22 is provided with an external thread, the mounting seat 24 and the vertical driving rod 22 are connected by threaded matching, the vertical guide rod 23 passes through the mounting seat 24, the mounting seat 24 is fixedly mounted with the third motor 25, the driving shaft of the third motor 25 is fixedly connected to the rotating frame 26, wherein the second motor 21 and the vertical guide rod 23 are both fixedly mounted on the bed frame 1;

[0044] At the same time, the upper end surface of the corner of the bed frame 41 and the lower end surface thereof are provided with a supporting groove 411;

[0045] The bed board assembly 4 at the bottom overlaps the supporting groove 411 of the lower end surface of the adjacent bed board frame 41 through the rotating frame 26 of any lifting assembly 2 at the diagonal line, so that the bed board assembly 4 at the bottom overlaps the lifting assembly 2;

[0046] The upper bed board assembly 4 overlaps the supporting groove 411 of the lower end surface of the adjacent bed board frame 41 through the rotating frame 26 of the lifting assembly 2 on the diagonal line, so that the upper bed board assembly 4 overlaps the lifting assembly 2.

[0047] When in use, the second motor 21 drives the vertical driving rod 22 to rotate, so that the mounting seat 24 is lifted and lowered, and then the corresponding bed board assembly 4 is driven to be lifted and lowered through the rotating frame 26 .

[0048] like Figure 3 As shown, in this embodiment, the flip assembly 3 includes a rotating shaft 31, a U-shaped groove rod 32, a fourth motor 33, a cylinder 34 and a limit block 35, wherein the rotating shaft 31 is arranged as a pair, and the pair of rotating shafts 31 are respectively located at the two ends of the lower bed board assembly 4, wherein the rotating shaft 31 is rotatably connected with the bed frame 1, and one end of the rotating shaft 31 close to the bed board assembly 4 is fixedly installed with a U-shaped groove rod 32, and a pair of cylinders 34 are fixedly installed on the back side of the U-shaped groove rod 32, and one end of the piston rod of the cylinder 34 is fixedly installed with a limit block 35, wherein the limit block 35 penetrates the U-shaped groove rod 32, and part of the limit block 35 extends into the U-shaped groove of the U-shaped groove rod 32;

[0049] One end of any rotating shaft 31 is fixedly connected to the driving shaft of the fourth motor 33;

[0050] At the same time, fixedly connected overlapping blocks 412 are provided at both ends of the bed board frame 41. When the adjacent bed board assembly 4 needs to be flipped over as a whole, the overlapping blocks 412 are located in the U-shaped groove of the U-shaped groove rod 32, and the overlapping blocks 412 are located between the limit blocks 35 on the same side.

[0051] When in use, when the patient needs to be changed between the supine position and the prone position, the lifting assembly 2 drives the bed board assembly 4 at the same time, so that the upper bed board assembly 4 is lowered to be attached to the lower bed board assembly 4, at which time the patient is in the storage groove, and at the same time, the lap block 412 on the bed board frame 41 of the bed board assembly 4 is in the U-shaped groove of the U-shaped groove rod 32, and the lap block 412 is located between the limit blocks 35 on the same side;

[0052] The third motor 25 is driven, so that the driving shaft of the third motor 25 drives the rotating frame 26 to rotate, so that the rotating frame 26 is separated from the lifting groove 411. At this time, the lifting assembly 2 of the mirror distribution is integrally overlapped on the limit block 35 at the bottom. At this time, the fourth motor 33 is driven, and the fourth motor 33 drives the U-shaped groove rod 32 to rotate through the rotating shaft 31. The U-shaped groove rod 32 drives the lifting assembly 2 of the mirror distribution to flip as a whole, so that the patient can switch between the supine position and the prone position;

[0053] After the transformation is completed, the driving shaft of the third motor 25 drives the rotating frame 26 to rotate, so that the rotating frame 26 returns to the supporting groove 411 of the bed board assembly 4 to lift the bed board assembly 4, and the piston rod of the cylinder 34 drives the limit block 35 to move until the limit block 35 is separated from the U-shaped groove of the U-shaped groove rod 32. Thereafter, the upper bed board assembly 4 is raised through the lifting assembly 2, so that a certain interval is formed between the bed board assemblies 4, which is convenient for medical staff to observe or operate on the patient on the lower bed board assembly 4.

[0054] Working principle:

[0055] During use, when a patient lying in a supine position on the bed board assembly 4 needs to be turned into a prone position, the lifting assembly 2 drives the upper bed board assembly 4 to move downward to clamp the patient on the lower bed board assembly 4. After clamping, the turning assembly 3 turns the mirror-arranged bed board assembly 4 as a whole, so that the patient lying in a supine position on the bed board assembly 4 needs to be turned into a prone position. In this way, the patient in a supine position can be turned into a prone position, and similarly, the patient in a prone position can also be turned into a supine position; thereafter, the upper bed board assembly 4 rises to form a certain interval between the bed board assemblies 4, which is convenient for medical staff to observe or operate on the patient on the lower bed board assembly 4.
