DETAILED DESCRIPTION

[0037] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0038] Example 1

[0039] A lower limb positioning device for gynecological examination, Figure 1-4 As shown in the figure, it includes a base 1, a lifting plate 2, a return spring 3, a bed board 4, a support mechanism 5 and a backrest mechanism 6. A lifting plate 2 is slidably provided on the top of the base 1, and four return springs 3 are evenly connected between the bottom of the lifting plate 2 and the top of the base 1. A bed board 4 for the patient to lie on is welded on the top of the lifting plate 2. A cotton pad is attached to the middle of the top of the bed board 4 to facilitate the patient to sit accurately in the designated position. It can be replaced and is more hygienic. A support mechanism 5 for limiting the patient's legs is provided on the front inner side of the base 1, and a backrest mechanism 6 for the patient to lean on with his back is connected between the lifting plate 2 and the rear side of the bed board 4.

[0040] exist Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown in the figure, the supporting mechanism 5 includes a top frame 51, a supporting rod 52, a rotating plate 53, a first torsion spring 54, a movable frame 55 and a supporting plate 56. The top frame 51 is welded on the front side of the lifting plate 2, and a supporting rod 52 is provided on the inner front side of the base 1. A rotating plate 53 is rotatably provided on the support rod 52. The top frame 51 is in contact with the rotating plate 53. The first torsion spring 54 is connected between the left and right sides of the rotating plate 53 and the supporting rod 52. A movable frame 55 is rotatably provided on the left and right front side of the top of the rotating plate 53. Support plates 56 for supporting the patient's legs are provided on the top of the two movable frames 55. The support plates 56 are arc-shaped, and the two support plates 56 are both located at the bottom of the bed board 4.

[0041] exist Figure 1 , Figure 2, Figure 8 and Fig. 9 As shown in the figure, the backrest mechanism 6 includes a support block 61, a cushion 62, a guide frame 63, a support frame 64, an electric push rod 65 and a guide rod 66. The support block 61 is symmetrically provided on the upper rear side of the base 1, and a cushion 62 for a backrest is rotatably provided between the upper sides of the two support blocks 61. The bottom of the cushion 62 is symmetrically connected to the guide frame 63 by bolt connection. A support frame 64 is provided on the rear side of the bottom of the lifting plate 2, and an electric push rod 65 is installed on the support frame 64. A guide rod 66 is provided on the telescopic rod of the electric push rod 65, and the guide rod 66 is connected to the two guide frames 63 in a sliding and rotatable manner.

[0042] When people need to use the device for gynecological examination, they can first sit in the middle of the bed board 4. At this time, the bed board 4 will move downward under the action of gravity, thereby driving the lifting plate 2 to move downward, and the return spring 3 will be compressed accordingly. The lifting plate 2 moves downward and drives the top frame 51 to move downward, so that the top frame 51 pushes the rotating plate 53 to rotate, and the first torsion spring 54 is deformed accordingly. The rotation of the rotating plate 53 drives the movable frame 55 and the supporting plate 56 to move upward, and the patient's legs can be supported on the supporting plate 56, so that the supporting plate 56 props up the patient's legs. The downward movement of the lifting plate 2 and the bed board 4 can drive the backrest mechanism 6 moves downward. After people's legs lean on the support plate 56, people can start the electric push rod 65, so that the telescopic rod of the electric push rod 65 extends to drive the guide rod 66 to move upward, so that the guide rod 66 pushes the guide frame 63 and the cushion 62 to rotate. The cushion 62 rotates to facilitate the patient's back to lean on it. After the angle of the cushion 62 is adjusted to a suitable angle, people can close the electric push rod 65, so that the patient's back leans on the cushion 62 more comfortably, so as to better cooperate with the doctor for examination. The patient can half lie on the cushion 62, and the doctor can examine the patient's lower body. The support plate 56 can be used to check the patient's double-legged body. The legs are limited, which is convenient for medical staff to check and prevent the patient from moving his legs around due to pain, which affects the examination. After the patient is examined, the medical staff can lift the patient up from the bed board 4, so that the bed board 4 is no longer stressed, and the lifting plate 2 will drive the bed board 4 to move upward under the reset action of the return spring 3. The lifting plate 2 and the bed board 4 move upward and then drive the backrest mechanism 6 to move upward and reset as a whole. The lifting plate 2 moves upward and drives the top frame 51 to move upward, so that the top frame 51 no longer presses the rotating plate 53, so that the rotating plate 53 is reversely rotated and reset under the reset action of the first torsion spring 54, thereby driving the movable The frame 55 and the support plate 56 move downward and reset, so that the support plate 56 is located below the lifting plate 2. In this way, one patient has been examined and can be examined by other patients. When the device is not in use, in order to reduce the overall area of ​​the device, people can control the electric push rod 65 to operate in the reverse direction, so that the telescopic rod of the electric push rod 65 retracts and drives the guide rod 66 to move downward, so that the guide rod 66 drives the guide frame 63 and the cushion 62 to rotate in the opposite direction, so that the cushion 62 reverses and resets to a horizontal state, and people can close the electric push rod 65. In this way, the overall area of ​​the device is reduced and will not occupy more space in the ward.

[0043] Example 2

[0044] On the basis of Example 1, Figure 1 , Figure 2 , Fig.10 and Fig.11As shown in the figure, a headrest mechanism 7 is also included, which includes a connecting rod 71, a head pad 72, a fixed frame 73, a sliding frame 74 and a return spring 75. Two connecting rods 71 ​​are slidably provided on the left and right sides of the cushion 62, and five oblique grooves are evenly opened on the four connecting rods 71. A head pad 72 for resting the head is connected between the rear sides of the four connecting rods 71. A fixed frame 73 is provided on the rear side of the bottom of the cushion 62. A sliding frame 74 that can clamp the connecting rod 71 is slidably provided on the fixed frame 73. Return springs 75 are connected between the left and right sides of the sliding frame 74 and the fixed frame 73. The upper front wall of the sliding frame 74 is an inclined surface, and the sliding frame 74 is engaged with the oblique groove.

[0045] When the patient sits on the bed board 4, the bed board 4 and the lifting board 2 are forced to move downward, and the backrest mechanism 6 moves downward as a whole, which will also drive the headrest mechanism 7 to move downward. When people adjust the angle of the cushion 62, the rotation of the cushion 62 will also drive the headrest mechanism 7 to rotate as a whole. After the angle of the cushion 62 is adjusted, the angle of the head pad 72 can be adjusted next. People can directly pull the head pad 72 upward to drive the connecting rod 71 to move upward, so that the oblique groove on the connecting rod 71 pushes the sliding frame 74 to move backward, and the reset spring 75 is compressed accordingly. When the next oblique groove on the connecting rod 71 is aligned with the sliding frame 74, the sliding frame 74 will move forward and reset under the reset action of the reset spring 75, and then be stuck in the oblique groove. The connecting rod 71 continues to move upward, which will intermittently push the sliding frame 74, and then The sliding frame 74 is staggered, and after the head pad 72 moves to a suitable height, the sliding frame 74 can be reset and stuck in the oblique groove, thereby fixing the head pad 72, and the patient's head can rest on the head pad 72. Similarly, if the height of the head pad 72 needs to be adjusted downward, people can pull the sliding frame 74 backward so that it no longer gets stuck in the oblique groove, and the reset spring 75 is compressed accordingly, and people can pull the head pad 72 downward, driving the connecting rod 71 to move downward, and then the height of the head pad 72 can be adjusted. After the adjustment is completed, the sliding frame 74 is released, so that the sliding frame 74 moves forward and resets and gets stuck in the oblique groove under the reset action of the reset spring 75. In this way, the patient's head has a supported position, which can improve comfort. When people adjust the angle of the back cushion 62 to the horizontal state, it will drive the headrest mechanism 7 to reverse and adjust as a whole.

[0046] exist Figure 1 , Figure 2 , Fig.12 , Fig.13 and Fig.14As shown in the figure, it also includes a dustproof mechanism 8, which includes a rotating shaft 81, a spiral spring 82 and a rotating frame 83. The rotating shafts 81 are connected to the left and right sides of the front of the bed board 4. The two rotating shafts 81 are rotatably provided with rotating frames 83 that can play a dustproof role. The two rotating frames 83 are connected to the two rotating shafts 81 with spiral springs 82. The two rotating frames 83 are both rotatably matched with the bed board 4, and the two rotating frames 83 are both in contact with the support plate 56 on the same side.

[0047] The support plate 56 will no longer push the rotating frame 83, and the rotating frame 83 will rotate in the opposite direction under the resetting action of the spiral spring 82, and the rotating frame 83 can play a dustproof role for the support plate 56 to prevent external dust from entering the interior of the bed board 4.

[0048] exist Figure 1 , Figure 2 and Fig.15 As shown in the figure, it also includes a fixing mechanism 9, which includes a mounting frame 91, a movable block 92, a second torsion spring 93 and a handle 94. The tops of the two rotating frames 83 are connected to the mounting frames 91 by bolts. The front and rear sides of the two mounting frames 91 are rotatably provided with movable blocks 92 that can prevent the patient's legs from moving around. The two movable blocks 92 on the left and right sides are in contact with the support plate 56 on the same side. The second torsion spring 93 is connected between the movable blocks 92 on the left and right sides and the mounting frame 91 on the same side. The handle 94 is connected between the two movable blocks 92 on the left and right sides, and the movable blocks 92 are in contact with the bed board 4.

[0049] exist Figure 1 , Figure 2 , Fig.16 and Fig.17As shown in the figure, it also includes a transmission mechanism 10, which includes a pushing frame 101, a block 102, a compression spring 103, a rotating rod 104 and a third torsion spring 105. The two mounting frames 91 are both slidably provided with a pushing frame 101, and two compression springs 103 are connected between the two pushing frames 101 and the mounting frames 91 on the same side. Blocks 102 are connected to the inner sides of the two mounting frames 91, and the two blocks 102 are engaged with the handles 94 on the same side. The front parts of the two pushing frames 101 are both rotatably provided with rotating rods 104, and the two rotating rods 104 are connected to the pushing frames 101 on the same side with third torsion springs 105, and the two rotating rods 104 are in contact with the bed board 4.

[0050] When the patient needs to undergo a lower body examination, initially the third torsion spring 105 is in a deformed state. After the patient sits on the bed board 4, the bed board 4 and the lifting board 2 are forced to move downward, so that the support plate 56 gradually moves upward, thereby causing the rotating frame 83 to drive the fixing mechanism 9 to rotate as a whole, and the fixing mechanism 9 will also drive the transmission mechanism 10 to rotate. The rotation of the pushing frame 101 will gradually reset the third torsion spring 105, and the rotating rod 104 is in a horizontal state at this time, and no longer contacts the bed board 4. At this time, the patient can lean his legs on the support board 56, and at the same time, the patient's legs will squeeze the rotating rod 104, thereby driving the rotating rod 104 and the pushing frame 101 to move downward, and the compression spring 103 will be compressed accordingly, so that the pushing frame 101 drives the card block 102 to move downward. Initially, the third torsion spring 105 is in a deformed state. The second torsion spring 93 is deformed, and the block 102 moves downward and no longer blocks the handle 94. The movable block 92 will rotate and reset in the opposite direction under the reset action of the second torsion spring 93, thereby driving the handle 94 to reverse and reset. In this way, the movable block 92 will contact the support plate 56, thereby limiting the patient's legs, which can prevent the patient's legs from shaking during the examination. After the patient's examination is completed, the medical staff can manually pull the handle 94 to drive the movable block 92 to rotate, and the second torsion spring 93 is deformed. The movable block 92 rotates and no longer contacts the support plate 56, and the patient can get up and leave the bed board 4. The patient's legs are separated from the rotating rod 104 and the support plate 56. At the same time, the bed board 4 and the lifting plate 2 move upward. After the rotating rod 104 is no longer subjected to force, the push frame 101 Under the restoring action of the compression spring 103, the block 102 and the rotating rod 104 will be driven to move upward and reset. At this time, people can loosen the handle 94, so that the movable block 92 drives the handle 94 to rotate in the opposite direction and reset due to the restoring action of the second torsion spring 93. At this time, the handle 94 is not stuck by the block 102. After the patient leaves the bed board 4, the rotating frame 83 will drive the fixing mechanism 9 and the transmission mechanism 10 to rotate in the opposite direction as a whole, so that the movable block 92 gradually contacts the bed board 4. The movable block 92 will be blocked by the bed board 4, and the mounting frame 91 continues to reverse with the rotating frame 83, so that the second torsion spring 93 is deformed, and the block 102 and the pushing frame 101 continue to rotate, the block 102 will push the handle 94, and the handle 94 cannot move, so that the block 1 02 moves outward due to its own inclined surface, thereby driving the pushing frame 101 and the rotating rod 104 to move outward, and the compression spring 103 is compressed accordingly. After the block 102 passes over the handle 94, the pushing frame 101 will drive the block 102 and the rotating rod 104 to move inward and reset under the reset action of the compression spring 103, so that the block 102 will jam the handle 94. At the same time, when the pushing frame 101 reverses and resets to a certain extent, the rotating rod 104 contacts the bed board and cannot rotate, causing the third torsion spring 105 to gradually deform and then return to the initial state. In this way, under the action of the transmission mechanism 10, the movable block 92 can automatically reverse to limit the patient's legs after the patient's legs are placed, thereby reducing the operating burden of medical staff.

[0051] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
