DETAILED DESCRIPTION

[0036] To make the technical solution of the present invention clearer, the following Figure 1-9 The present invention is further described in detail with reference to the specific embodiments.

[0037] A relaxation device for pregnant women during MRI examination, comprising a slide 1, a base frame 2 is fixed on the upper surface of the slide 1, a middle plate 3 is fixed on the upper inner side of the base frame 2, the left and right ends of the middle plate 3 are rotatably connected with a rotating shaft 4, an upper body plate 5 is fixed on the outer surface of the rotating shaft 4 on the right side, a lower body plate 6 is fixed on the outer surface of the rotating shaft 4 on the right side, a middle column 7 is fixed on the front and rear surfaces of the middle plate 3, a turntable 8 is rotatably connected to the outer surface of the middle column 7, a gear ring 9 is fixed on the side of the turntable 8 close to the middle plate 3, a spur gear 10 is fixed on the front and rear ends of the rotating shaft 4 located inside the two gear rings 9, a slide plate 11 is slidably connected to the inside of the middle column 7, and a screw rod 12 is threadedly connected to the end of the middle column 7 away from the middle plate 3, and the screw rod 12 is threadedly connected to the end of the middle column 7 away from the middle plate 3. One end of 12 near the middle plate 3 penetrates into the middle column 7 and is rotatably connected with the slide plate 11. The end of the slide plate 11 near the turntable 8 is symmetrically fixed with an insertion rod 13. A plurality of insertion holes 14 are opened inside the middle column 7. The plurality of insertion holes 14 are distributed in a circular array, and the insertion holes 14 are adapted to the insertion rod 13. The device has three forms for pregnant women to use, namely, sitting, lying flat, and lying on the side, which can greatly improve the comfort of pregnant women, relax them, and reduce tension. The device is slidably connected with the external straight rail through the slide seat 1 at the bottom. When the pregnant woman lies on the device, the device can drive the pregnant woman to move into the MRI instrument for examination through the slide seat 1.

[0038] The personnel rotate the turntable 8 and the gear ring 9 on one side, and the two spur gears 10 are rotated under the transmission of the gear ring 9, and the lower body plate 6 on the left side is turned down through the rotating shaft 4, and the upper body plate 5 on the right side is turned up and tilted. The two rotate counterclockwise at the same time, but in different states, forming a seat state. The slide plate 11 and the insertion rod 13 are moved by rotating the screw rod 12, and the insertion rod 13 is inserted into the insertion hole 14 to fix the shape. The pregnant woman can sit on the device. After calming down, the reverse operation is performed to make the device a lying device, and the pregnant woman can lie down flat.

[0039] After pregnancy, the pregnant woman's body will undergo many changes, such as an enlarged abdomen and a change in center of gravity. Lying down directly may cause greater pressure on the abdomen and waist, causing discomfort. However, if you slowly lie down from a sitting position, the center of gravity of the body will gradually shift, and the pressure on various parts will gradually change. Pregnant women will have time to adjust their body posture and find a more comfortable position to reduce discomfort.

[0040] Reference Figure 1-2 A bottle rack 15 is fixed to the lower surface of the upper body board 5, and an oxygen cylinder 16 is arranged inside the bottle rack 15. When the pregnant woman sits or lies down, the oxygen cylinder 16 is connected to the oxygen cylinder 16 through the oxygen inhalation tube to supply oxygen to the pregnant woman; for some pregnant women who have breathing difficulties, chest tightness and other discomfort symptoms, oxygen inhalation can relieve these symptoms and make the body feel more comfortable; during the examination, the comfort of the body can help pregnant women relax their tense emotions; pregnant women can focus on the rhythm of breathing and the feeling of oxygen entering the body, so that their mood gradually calms down.

[0041] Reference Figure 1-6 , plate grooves 17 are provided on the front and rear sides of the upper surface of the middle plate 3, and a side plate 18 is provided inside the plate groove 17. A frame plate 19 is fixed on the inner side of the bottom frame 2, and a rotating frame 20 is rotatably connected inside the frame plate 19. The front and rear ends of the top of the rotating frame 20 respectively penetrate into the lower surfaces of the two plate grooves 17. A support plate 21 is fixed on the left side of the lower surface of the bottom frame 2, and a rotating rod 22 is rotatably connected to the right side of the support plate 21. A gear cylinder 23 is fixed on the outer surface of the rotating rod 22 below the rotating frame 20, and a bevel gear 24 is fixed on the right end of the rotating rod 22. The front end of the bevel gear 24 is meshed and connected with a bevel gear 25. A rotating rod 26 is fixed at the center of the front surface of the bevel gear 25. The front end of the rotating rod 26 penetrates to the front of the bottom frame 2 and is fixed with an operating wheel 27;

[0042] The left side of the support plate 21 is rotatably connected to two spur gears 28, a rotating rod 3 29 is fixed in the middle of the spur gear 28, and the right ends of the two rotating rods 3 29 both penetrate to the right side of the support plate 21, and the outer surface of the rotating rod 1 22 is located on the left and right sides of the rotating frame 20 and are fixed with ratchets 30, and the outer surfaces of the two rotating rods 3 29 are fixed with pawls 31, the left pawl 31 is engaged with the left ratchet 30, and the right pawl 31 is engaged with the right ratchet 30, and the ratchet teeth of the two ratchet wheels 30 limit the rotation direction in opposite directions;

[0043] A guide rod 32 is fixed on the left side of the lower surface of the frame plate 19, and a lifting frame 33 is slidably connected to the outer surface of the guide rod 32. A tension spring 34 is arranged on the outer surface of the guide rod 32 above the lifting frame 33, and the tension spring 34 is fixedly connected to the lifting frame 33 and the frame plate 19 respectively;

[0044] A through arc groove 42 is provided on the lower surface of the plate groove 17, and an arc plate 43 is slidably connected inside the arc groove 42. The top of the arc plate 43 is fixedly connected to the lower surface of the side plate 18. The arc plate 43 and the arc groove 42 are coaxial with the rotating frame 20 to avoid dead points during rotation. When the rotating frame 20 rotates to push the side plate 18 to flip, the side plate 18 will slide along the arc groove 42 through the arc plate 43.

[0045] When the pregnant woman is lying down, the staff first presses the lifting frame 33 to lower it, and the spur gear 28 drives the rotating rod 3 29 and the ratchet 31 to rotate under the transmission of the lifting frame 33, and the ratchet 31 moves away from the corresponding ratchet 30 to release the lock on it. At this time, the staff can rotate the operating wheel 27 to rotate the rotating rod 26 and the bevel gear 25, and then rotate the rotating rod 1 22 and the gear cylinder 23 on its surface and the two ratchet wheels 30 under the transmission of the bevel gear 1 24. The gear cylinder 23 engages and drives the rotating frame 20 to move, rotate along its center of circle, and pushes to drive the side body board 18 in the corresponding direction to flip, and the side body board 18 will support the pregnant woman's hips and assist her in lying sideways for detection;

[0046] In the middle and late stages of pregnancy, the abdomen of pregnant women increases significantly. Lying on your back for a long time may cause great pressure on the abdomen, back and waist, causing discomfort. Lying on your side can disperse the weight of the pregnant woman's body to one side, reduce the pressure on the abdomen, make the pregnant woman feel more comfortable, and it is difficult for pregnant women to turn over. Lying on your side can save effort.

[0048] When the rotating frame 20 rotates to push one side plate 18 to flip, the other end will move away from the other side plate 18. When the guide block 40 on this side disengages from the extrusion groove 38, the compressed spring 39 will push the two spring blocks 37 into the card slot 41, so that the side plate 18 at this location is fixed, and the guide block 40 at the end where the rotating frame 20 pushes and flips the side plate 18 is inclined to squeeze the extrusion groove 38 so that the spring block 37 shrinks and disengages from the card slot 41, so that the side plate 18 can achieve the effect of flipping with the push of the rotating frame 20. The fixation of the side plate 18 and the middle plate 3 can prevent the pregnant woman from shaking the side plate 18 during the sideways process, thereby avoiding affecting the pregnant woman.
