[0032] As Figure 1 , Figure 2 , Figure 6 and Figure 7 , a movable postoperative position chair for ophthalmology of the embodiment includes base 1, four rollers 2 hingedly arranged at the four corners of base 1, a rotating belly board 3 movably arranged above base 1, a face placement slot 4 arranged in the middle of rotating belly board 3 in the thickness direction, a cavity 5 arranged in rotating belly board 3, a support position adjusting assembly 6 arranged in cavity 5 and used for changing the support position of face, a pair of height adjusting assemblies 7 respectively arranged between base 1 and rotating belly board 3 on the left and right sides and used for adjusting the height position of rotating belly board 3, a pair of corner adjusting assemblies 8 respectively arranged between each height adjusting assembly 7 and rotating belly board 3 on the upper part and used for adjusting the rotating angle of rotating belly board 3, a fixed hot compress assembly 9 arranged on rotating belly board 3 and used for attaching hot compress towel on the non-supported and pressed part, and four locking assemblies 10 respectively arranged on each roller 2.

[0033] The support part adjusting assembly 6 comprises a pair of front and rear sliding grooves 61 arranged on the front and rear sides of the inner wall of the face placing groove 4 along the front and rear directions and connected with the cavity 5, a pair of first face support plates 62 movably arranged in the front and rear sliding grooves 61 along the front and rear directions, a pair of front and rear transmission rods 63 fixedly arranged at the ends of the first face support plates 62 away from the center of the face placing groove 4 and towards the left side in the cavity 5, a front and rear distance adjusting screw 64 rotatably arranged between the front and rear transmission rods 63, a pair of front and rear transmission sleeves 65 threadedly arranged on the front and rear ends of the front and rear distance adjusting screw 64 and fixedly connected with the front and rear transmission rods 63, a first driving turntable 66 fixedly arranged on the middle part of the front and rear distance adjusting screw 64 and extending downwards below the rotating deck 3, an avoidance track 67 arranged in the rear first face support plate 62 along the left and right directions, a pair of left and right sliding grooves 68 arranged on the left and right sides of the inner wall of the face placing groove 4 along the left and right directions and connected with the cavity 5, a pair of second face support plates 69 movably arranged in the left and right sliding grooves 68 along the left and right directions, a pair of left and right transmission rods 610 fixedly arranged at the ends of the second face support plates 69 away from the center of the face placing groove 4 and towards the rear side in the cavity 5, a left and right distance adjusting screw 611 rotatably arranged between the left and right transmission rods 610 and arranged in the avoidance track 67, a pair of left and right transmission sleeves 612 threadedly arranged on the left and right ends of the left and right distance adjusting screw 611 and fixedly connected with the left and right transmission rods 610, and a second driving turntable 613 fixedly arranged on the rear part of the left and right distance adjusting screw 611 and extending downwards below the rotating deck 3.

[0034] The two front and rear transmission sleeves 65 are threadedly connected with the front and rear distance adjusting screw 64 in opposite directions, and the two left and right transmission sleeves 612 are threadedly connected with the left and right distance adjusting screw 611 in opposite directions.

[0035] When the product is used, the bottom of the rotating stomach board 3 is rotated to the lower part of the first driving turntable 66, which drives the front and rear distance adjusting screw rod 64 to rotate, thereby driving the front and rear transmission sleeves 65 at both ends of the front and rear distance adjusting screw rod 64 to move towards the front and rear distance adjusting screw rod 64, so that the front and rear transmission rods 63 on both sides are driven by the corresponding front and rear transmission sleeves 65 to move towards the center of the face placing groove 4, and the first face supporting plates 62 on both sides move synchronously with the front and rear transmission rods 63, until they are extended to the corresponding front and rear sliding grooves 61 to respectively correspond to the patient's forehead position and chin position, and the first driving turntable 66 is stopped. At this time, the patient stretches his face into the face placing groove 4, and the patient's forehead position and chin position respectively abut against the first face supporting plates 62 on both sides, which supports the patient's forehead and chin to support the patient's face. After the patient's forehead and chin are supported for a long time, the patient lifts his head, reversely rotates the first driving turntable 66, drives the first elastic support wrapping head 621 on both sides to extend into the corresponding front and rear sliding grooves 61, and then rotates the second driving turntable 613, drives the left and right distance adjusting screw rod 611 to rotate, thereby driving the left and right transmission sleeves 612 at both ends of the left and right distance adjusting screw rod 611 to move towards the left and right distance adjusting screw rod 611, so that the left and right transmission rods 610 on both sides are driven by the corresponding left and right transmission sleeves 612 to move towards the center of the face placing groove 4. The second face supporting plates 69 on both sides move synchronously with the left and right transmission rods 610, until they are extended to the corresponding left and right sliding grooves 68 to respectively correspond to the patient's cheeks on both sides, and the second driving turntable 613 is stopped. At this time, the patient again stretches his face into the face placing groove 4, and the patient's cheek position on both sides respectively abuts against the second elastic support wrapping head 691 on both sides, which supports the patient's cheeks on both sides to support the patient's face, thereby releasing the pressure on the patient's forehead and chin. Thus, the discomfort of the patient caused by long-term support and compression at the same skin position is solved.

[0036] As shown in Figure 1 , Figure 2 and Figure 6 , the two first face supporting plates 62 are wrapped with first elastic support wrapping heads 621 at one end close to the center of the face placing groove 4, and the two second face supporting plates 69 are wrapped with second elastic support wrapping heads 691 at one end close to the center of the face placing groove 4.

[0037] When the product is used, the first elastic support wrapping head 621 flexibly abuts against the patient's forehead and chin, and the second elastic support wrapping head 691 flexibly abuts against the patient's cheeks, thereby reducing the discomfort of the patient when he is prone.

[0038] As shown in Figure 1 , Figure 2 and Figure 3As shown, the fixed hot compress assembly 9 includes an upper elastic compress strip 91 fixed to the upper side of the rotating face plate 3 along the left-right direction and placed in the face placing groove 4 at the position corresponding to the forehead, a lower elastic compress strip 92 fixed to the upper side of the rotating face plate 3 along the left-right direction and placed in the face placing groove 4 at the position corresponding to the chin, a middle elastic compress strip 93 fixed to the right side of the upper side of the rotating face plate 3 and placed in the face placing groove 4 along the left-right direction at the position corresponding to the cheek, a female buckle 94 fixed to the left side of the upper side of the rotating face plate 3, and a male buckle 95 fixed to the lower side of the free end of the middle elastic compress strip 93 and connected to the female buckle 94.

[0039] In use, in order to relax the facial muscles of the patient, when the second elastic support wrapping heads 691 on both sides are extended, hot compress towels are placed in the middle of the upper elastic compress strip 91 and the lower elastic compress strip 92, the patient places the forehead and the chin in the middle of the upper elastic compress strip 91 and the lower elastic compress strip 92 respectively, and relaxes, which drives the middle of the upper elastic compress strip 91 and the lower elastic compress strip 92 to press downward, and under the action of the elastic force, the hot compress towels on both sides are tightly attached to the forehead and the chin of the patient respectively.

[0040] When the first elastic support wrapping heads 621 on both sides are extended, the male buckle 95 is buckled on the female buckle 94, and a hot compress towel is placed in the middle of the middle elastic compress strip 93, the patient places the cheeks on the middle elastic compress strip 93, and relaxes, which drives the middle elastic compress strip 93 to press downward, and under the action of the elastic force, the hot compress towel is tightly attached to the cheek of the patient.

[0041] As shown in Figure 1 , Figure 2 and Figure 3 , each height adjusting assembly 7 includes a fixed sleeve 71 fixed to the base 1 along the height direction, a height adjusting rod 72 movably sleeved in the fixed sleeve 71 along the height direction, a plurality of pin holes 73 arranged on the side wall of the height adjusting rod 72 along the height direction and penetrating the height adjusting rod 72 along the front-rear direction, an alignment hole 74 penetrating the upper side wall of the fixed sleeve 71 along the front-rear direction, and a pin rod 75 arranged in the alignment hole 74 and fixedly connected with the corresponding pin hole 73.

[0042] In use, the pin rods 75 on both sides are pulled out, and then the corresponding height adjusting rods 72 are pulled upward respectively, and after being moved to the appropriate position, the pin rods 75 on the corresponding sides are inserted into the corresponding alignment holes 74 and fixedly connected with the corresponding pin holes 73, and the same operation is performed on the other side, so that after the height adjusting rods 72 on both sides are moved upward, the upper rotating face plate 3 is moved upward to the height position suitable for the patient.

[0043] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, each angle adjustment assembly 8 includes a fixed plate 81 fixed to the lower side of the rotating platform 3, a threaded hole 82 passing through the upper part of the height adjustment rod 72 corresponding to the fixed plate 81 in the left-right direction, a locking threaded rod 83 threadedly connected in the threaded hole 82 and passing through the fixed plate 81 in the thickness direction, an anti-slip plate 84 fixed to one end of the locking threaded rod 83 that protrudes from the fixed plate 81, and a rotating handle 85 fixed to the end of the locking threaded rod 83 away from the fixed plate 81.

[0044] When using this product, rotate the handles 85 on both sides to loosen the locking threaded rods 83 on both sides, causing the anti-slip plates 84 on both sides to move away from the corresponding fixed plate 81. This removes the friction restriction of the anti-slip plates 84 from the fixed plate 81, allowing the fixed plate 81 to rotate the rotating platform 3 back and forth. The patient lies on the rotating platform 3, and after adjusting the angle of the rotating platform 3 to a suitable position, rotate the handles 85 on both sides again to tighten the locking threaded rods 83 on both sides. This causes the locking threaded rods 83 to bring the anti-slip plates 84 on both sides into contact with the side wall of the fixed plate 81. The friction between the anti-slip plates 84 and the fixed plate 81 restricts the rotation of the fixed plate 81, thus fixing the rotating platform 3.

[0045] like Figure 1 , Figure 2 and Figure 8 As shown, each locking assembly 10 includes a fixed seat 101 fixed on the hinge seat of the roller 2 in the front-to-back direction, a brake plate 102 rotatably disposed on the fixed seat 101 in the up-down direction, and a friction pad 103 fixed on the lower side of the brake plate 102.

[0046] When using this product, after pushing the device to the appropriate position, stepping down on each brake plate 102 causes the friction pad 103 to abut against the side wall of the corresponding roller 2, thereby limiting the rotation of each roller 2 through friction and achieving the effect of fixing the device.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, two rotating sleeves 11 are respectively sleeved in the middle of the two height adjustment rods 72. Each rotating sleeve 11 has a limiting plate 12 fixedly connected to the corresponding height adjustment rod 72 on its upper and lower sides. Two hand supports 13 are fixedly mounted on the side wall of the corresponding rotating sleeve 11 near the face placement slot 4. Two elastic anti-slip parts 14 are fixedly mounted inside the rotating sleeve 11. Two anti-rotation screws 15 are threadedly connected to the rotating sleeve 11 on the side away from the center of the face placement slot 4 and with one end near the center of the face placement slot 4 extending into the rotating sleeve 11 and abutting against the corresponding anti-slip parts 14.

[0048] When using this product, the patient places their arm on the two hand supports 13, and then loosens the two anti-rotation screws 15 to disengage them from the anti-slip parts 14. This prevents the anti-slip parts 14 from contacting the outer wall of the height adjustment rod 72, allowing the rotating sleeve 11 to rotate on the height adjustment rod 72. This adjusts the rotation position of the hand support 13 until the patient is in a comfortable position. Then, the anti-rotation screws 15 are tightened again, causing them to be screwed into the rotating sleeve 11. This causes the ends of the anti-rotation screws 15 to contact and push the anti-slip parts 14 towards the height adjustment rod 72, increasing the friction between the anti-slip parts 14 and the height adjustment rod 72, thus limiting the rotation of the rotating sleeve 11.

[0049] The working principle of this device is as follows:

[0050] Step 1: Push the device in front of the patient, and then step on the brake plate 102 on each roller 2 to make each friction pad 103 stick to the corresponding roller 2, thereby locking the rotation of each roller 2 and preventing the device from sliding when the patient is lying down.

[0051] Step 2: Pull out the pins 75 on both sides, and then pull the corresponding height adjustment rods 72 upward to the appropriate position. Then insert the corresponding pins 75 into the corresponding alignment holes 74 and lock them into the corresponding pin holes 73. Perform the same operation on the other side. As the height adjustment rods 72 on both sides move upward, the upper rotating plate 3 will move upward to a height position suitable for the patient.

[0052] Step 3: Rotate the handles 85 on both sides to loosen the locking threaded rods 83 on both sides, causing the anti-slip plates 84 on both sides to move away from the corresponding fixed plate 81. This removes the friction restriction of the anti-slip plates 84 on the fixed plate 81, allowing the fixed plate 81 to rotate back and forth. The patient lies on the rotating platform 3. After adjusting the angle of the rotating platform 3 to a suitable position, rotate the handles 85 on both sides again to tighten the locking threaded rods 83 on both sides. This causes the locking threaded rods 83 to bring the anti-slip plates 84 on both sides into contact with the side wall of the fixed plate 81. The friction between the anti-slip plates 84 and the fixed plate 81 restricts the rotation of the fixed plate 81, thus fixing the rotating platform 3.

[0053] Step 4: The patient places both arms on the hand supports 13 on both sides, and then loosens the anti-rotation screws 15 on both sides to disengage them from the anti-slip parts 14. This prevents the anti-slip parts 14 from contacting the outer wall of the height adjustment rod 72, allowing the rotating sleeve 11 to rotate on the height adjustment rod 72. This adjusts the rotation position of the hand supports 13 until the patient is in a comfortable position. Then, tighten the anti-rotation screws 15 again, causing them to be screwed into the rotating sleeve 11. This causes the end of the anti-rotation screws 15 to contact and push the anti-slip parts 14 towards the height adjustment rod 72, thereby increasing the friction between the anti-slip parts 14 and the height adjustment rod 72 and restricting the rotation of the rotating sleeve 11.

[0054] Step 5: Rotate the lower part of the first drive turntable 66 from the bottom of the rotating platform 3, which drives the front-to-back distance adjustment screw 64 to rotate. This causes the front-to-back transmission sleeves 65 at both ends of the front-to-back distance adjustment screw 64 to move in the direction of the front-to-back distance adjustment screw 64. As a result, the front-to-back transmission rods 63 on both sides are driven by the corresponding front-to-back transmission sleeves 65 to move towards the center of the face placement slot 4. The first face support plates 62 on both sides move synchronously with the front-to-back transmission rods 63 on both sides until they extend out of the corresponding front-to-back sliding grooves 61 to the positions corresponding to the patient's forehead and chin, respectively. Then stop rotating the first drive turntable 66. At this time, the patient puts their face into the face placement slot 4. The patient's forehead and chin positions abut against the first elastic support wrapping heads 621 on both sides, respectively. By supporting the patient's forehead and chin individually, the patient's face is supported.

[0055] Step 6: After the patient's forehead and chin have been supported for a long time, the patient raises their head and rotates the first drive turntable 66 in the opposite direction. This causes the first elastic support wrapping heads 621 on both sides to extend into the corresponding front and rear sliding grooves 61 for storage. Then, the second drive turntable 613 is rotated, causing the left and right distance adjustment screw 611 to rotate. This causes the left and right transmission sleeves 612 at both ends of the left and right distance adjustment screw 611 to move in the direction of the left and right distance adjustment screw 611. This causes the left and right transmission rods 610 on both sides to move towards the center of the face placement groove 4 by the corresponding left and right transmission sleeves 612. The second face support plates 69 on both sides move synchronously with the left and right transmission rods 610 on both sides until they extend out of the corresponding left and right sliding grooves 68 to the corresponding cheeks of the patient. The rotation of the second drive turntable 613 is then stopped. At this time, the patient puts their face into the face placement groove 4. The positions of the patient's cheeks are respectively abutted against the second elastic support wrapping heads 691 on both sides. By supporting the patient's cheeks individually, the patient's face is supported, thereby relieving the pressure on the patient's forehead and chin.

[0056] Step 7: Repeat steps 5 and 6 repeatedly, supporting the patient's forehead and chin or both cheeks in turn, thereby preventing discomfort caused by prolonged pressure on a single facial area.

[0057] Step 8: After a prolonged prone position, in order to soothe the patient's facial muscles, when the second elastic support wrapping heads 691 on both sides are extended, place hot compress towels in the middle of the upper elastic strip 91 and the lower elastic strip 92. The patient places their forehead and chin in the middle of the upper elastic strip 91 and the lower elastic strip 92 respectively, and relaxes, causing the middle of the upper elastic strip 91 and the lower elastic strip 92 to press down. Under the action of elasticity, the hot compress towels on both sides are pulled tightly and adhered to the patient's forehead and chin by the upper elastic strip 91 and the lower elastic strip 92 respectively.

[0058] Step 9: When the first elastic support wrapping head 621 on both sides extends, fasten the male buckle 95 onto the female buckle 94, and place a hot compress towel in the middle of the medium elastic dressing strip 93. The patient places their cheek on the medium elastic dressing strip 93 and relaxes, causing the medium elastic dressing strip 93 to press down. Under the action of elasticity, the hot compress towel is pulled tightly and adhered to the patient's cheek by the medium elastic dressing strip 93.

[0059] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
