DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0025] Example 1

[0026] An electrocardiogram examination couch, such as Figure 1-Figure 5 As shown, it includes a movable base 1, a first sliding block 2, a support rod 3, a second sliding block 4, a bed board 6, a rotating frame 7, an electrocardiograph 8, a guide assembly, an adjustment assembly and a replacement mechanism 12. The top of the movable base 1 is symmetrically slidably connected to the first sliding block 2, the top left side of the movable base 1 is symmetrically rotatably connected to the support rod 3, the first sliding block 2 is also rotatably connected to the support rod 3, the support rod 3 on the front left side is rotatably connected to the support rod 3 on the front right side, the support rod 3 on the rear left side is rotatably connected to the support rod 3 on the rear right side, a bed board 6 is provided above the movable base 1, the left side of the bottom of the bed board 6 is rotatably connected to the two support rods 3 on the same side, and the right side of the bottom of the bed board 6 slides symmetrically front and back. The second sliding block 4 is rotatably connected to the two support rods 3 on the other side. The rear side of the bed board 6 is rotatably connected to a rotating frame 7. An electrocardiograph 8 is installed on the rotating frame 7. The electrocardiograph 8 consists of a host 81, a signal line 82 and an electrode 83. When the subject lies on the bed board 6, the electrocardiograph 8 is located above the subject. By pulling out the signal line 82 and sticking the electrode 83 to the corresponding position of the subject's chest, the subject can be subjected to an electrocardiogram examination through the electrocardiograph 8. The guide component is used to guide the signal line 82. The movable base 1 is provided with an adjustment component for adjusting the height of the bed board 6. The bed board 6 is provided with a replacement mechanism 12. The guide component includes A wire-releasing box 91, a guide wheel 92 and a connecting ring 10 are installed on the main unit 81 at intervals in the circumferential direction. The wire-releasing boxes 91 correspond to the signal lines 82 one by one. The signal lines 82 are all wound around the adjacent wire-releasing boxes 91. A plurality of circular holes 71 are spaced circumferentially at the bottom of the rotating frame 7. The signal lines 82 extend from the adjacent circular holes 71. A connecting ring 10 is welded inside the rotating frame 7. A plurality of guide wheels 92 are rotatably connected to the connecting ring 10 at intervals in the circumferential direction. The signal lines 82 are in contact with the adjacent guide wheels 92. When the electrode 83 is separated from the subject's skin, the signal line 82 can be retracted through the wire-releasing box 91, thereby protecting the signal line 82. The guide wheel 92 and the circular hole 71 play a guiding role to prevent The signal line 82 is entangled, and the adjustment component includes a second motor 51 and a screw 52. The second motor 51 is symmetrically bolted to the front and back of the right side of the top of the movable base 1. The output shaft of the second motor 51 is connected to the screw 52 through a coupling. The left end of the screw 52 is rotatably connected to the movable base 1, and the first sliding block 2 is threadedly connected to the adjacent screw 52. By controlling the second motor 51 to drive the screw 52 to rotate, the first sliding block 2 moves to the left, driving the support rod 3 to rotate, so that the bed board 6 can be lifted. Similarly, by controlling the second motor 51 to drive the screw 52 to reverse, the first sliding block 2 moves to the right, and under the action of the support rod 3, the bed board 6 can move downward, thereby adjusting the height of the bed board 6.

[0027] like Figure 1 、 Figure 4 and Figure 5 As shown, the replacement mechanism 12 includes a first connecting frame 121, a rotating roller 122, a medical film 123, a mounting shell 124, a first motor 125, a spline shaft 126 and a spline sleeve 127. The first connecting frame 121 is symmetrically connected to the front and back of the right end of the bed plate 6. The rotating roller 122 is placed between the two first connecting frames 121. The left end of the bed plate 6 is connected to the mounting shell 124. The rear side of the mounting shell 124 is bolted to the first motor 125. The output shaft of the first motor 125 is connected to the spline shaft 126 through a coupling. A spline sleeve 127 is slidably connected to the spline shaft 126, and a medical film 123 is wound between the rotating roller 122 and the spline sleeve 127. The medical film 123 covers the top of the bed board 6. By controlling the first motor 125 to drive the spline shaft 126 to rotate, the spline sleeve 127 is driven to rotate, and the used medical film 123 can be folded up. At the same time, the medical film 123 will pull the rotating roller 122 to rotate, and the new medical film 123 can be loosened, thereby replacing the medical film 123.

[0028] When it is necessary to perform an electrocardiogram on the subject, the rotating frame 7 is manually rotated 180 degrees, driving the electrocardiograph 8 to rotate 180 degrees, thereby preventing the subject from being blocked by the electrocardiograph 8, and the initial height of the bed board 6 is low, which can facilitate the subject to lie on the bed board 6. After the subject lies on the bed board 6, the rotating frame 7 is manually reversed 180 degrees, driving the electrocardiograph 8 to rotate 180 degrees, so that the electrocardiograph 8 is located just above the patient's chest, and then the second motor 51 is controlled to drive the screw 52 to rotate. Under the action of the threaded connection, the first sliding block 2 moves to the left, driving the lower ends of the two support rods 3 on the right side to move to the left, thereby driving the support rods 3 to rotate, and the left The rotation of the two support rods 3 on the side will drive the second sliding block 4 to move to the left, so that the bed plate 6 can be lifted to a suitable height through the support rods 3, which is convenient for medical staff to perform electrocardiogram examination on the subject. Then, the signal line 82 is manually pulled downward to drive the electrode 83 to move downward so that the electrode 83 is attached to the corresponding position of the subject's chest. The guide wheel 92 will rotate under the action of friction. The guide wheel 92 and the circular hole 71 can guide the signal line 82 to separate the signal lines 82 from each other to prevent the signal lines 82 from being entangled. Then, the electrocardiogram examination can be performed on the subject by controlling the electrocardiograph 8. At this time, the signal line 82 is suspended vertically in the air, which can prevent the signal line 82 from hurting the subject. Causing compression, when the electrocardiogram examination is completed, the electrode 83 is separated from the subject's skin, and the signal line 82 can be reeled up through the wire box 91, thereby pulling the signal line 82 and the electrode 83 upward to reset and retract, which can protect the signal line 82, and then the rotating frame 7 and the electrocardiograph 8 are rotated 180 degrees, and the second motor 51 is controlled to drive the screw 52 to reverse, and similarly, the first sliding block 2 can be moved to the right to reset, driving the support rod 3 to reverse, thereby driving the bed board 6 to move downward to a lower position, making it easier for the subject to leave the bed board 6 and improving protection, and then controlling the first motor 125 to drive the spline shaft 126 to rotate counterclockwise, driving the spline sleeve 127 to rotate counterclockwise, The spline sleeve 127 can rewind the medical film 123, driving the rotating roller 122 to rotate counterclockwise. The rotating roller 122 will loosen the medical film 123, so that the medical film 123 can be automatically replaced. When the medical film 123 is used up, the spline sleeve 127 is pulled forward, the used medical film 123 is manually processed, and then the rotating roller 122 is taken out from the first connecting frame 121, and the new medical film 123 is put on the rotating roller 122, and the rotating roller 122 is placed on the two first connecting frames 121, and the new medical film 123 is passed around the top of the bed board 6 and then connected to the spline sleeve 127, so that the medical film 123 can be replaced.

[0029] Example 2

[0030] On the basis of Example 1, Figure 1 and Figure 6 As shown, it also includes an extension mechanism 11, which includes an extension plate 111, a connecting plate 112, a positioning block 113 and a first compression spring 114. The left part of the bed board 6 is slidably connected to the extension plate 111, and the medical film 123 passes through the extension plate 111. By pulling out the extension plate 111, the total length of the extension plate 111 and the bed board 6 can be increased, thereby facilitating the use of subjects with taller heights. A plurality of positioning blocks 113 are symmetrically and slidably connected to the bottom of the extension plate 111 at front and back intervals. The bottoms of the positioning blocks 113 are all curved surfaces. A first compression spring 114 is connected between the positioning blocks 113 and the extension plate 111. A connecting plate 112 is symmetrically welded to the lower left side of the bed board 6 at front and back. A plurality of positioning grooves 115 are spaced apart at the top of the connecting plate 112. The positioning blocks 113 are all stuck in adjacent positioning grooves 115. When the positioning blocks 113 are stuck in the positioning grooves 115 at different positions, the positioning blocks 113 can be positioned, thereby positioning the extension plate 111. When the subject lies on the bed board 6, the extension plate 111 is pulled to the left, driving the positioning block 113 to move to the left, and the connecting plate 112 will squeeze the positioning block 113 to move upward, and the first compression spring 114 is compressed. When the positioning block 113 is aligned with the next positioning groove 115, the first compression spring 114 returns to its original state, driving the positioning block 113 to move downward and reset, so that the positioning block 113 is stuck in the next positioning groove 115. By making the positioning block 113 stuck in the positioning groove 115 at different positions, the extension plate 111 can be positioned, so as to adjust the pulled-out length of the extension plate 111. At the same time, pulling out the extension plate 111 will drive the medical film 123 to extend, so that the medical film 123 covers the extension plate 111. In this way, it can adapt to the use of subjects with higher heights, and is convenient to use. When electrocardiogram examination is not needed, the extension plate 111 can be put away by pushing the extension plate 111 to the right to reset, thereby reducing the occupied space.

[0031] like Figure 1 and Figure 4As shown, it also includes a pressing mechanism 13, which includes a pressing frame 131 and a second compression spring 132. The front and rear sides of the bed plate 6 are slidably connected with the pressing frames 131. The pressing frames 131 are in contact with the medical film 123 and can press the medical film 123 to prevent the position of the medical film 123 from moving. The second compression spring 132 is symmetrically connected between the pressing frame 131 and the bed plate 6. Initially, the pressing frame 131 can press the medical film 123 to prevent the medical film 123 from moving. The medical film 123 is limited to prevent the position of the medical film 123 from moving. When the medical film 123 needs to be replaced, the pressing frame 131 is manually pulled upward, and the second compression spring 132 is compressed to separate the pressing frame 131 from the medical film 123, so that the medical film 123 can be replaced. Then the pressing frame 131 is released, and the second compression spring 132 returns to its original state, driving the pressing frame 131 to move downward and reset, so that the replaced medical film 123 can be pressed.

[0032] like Figure 1 、 Figure 7 、 Figure 8 and Figure 9As shown, it also includes a pushing mechanism 14, which includes a second connecting frame 141, a full gear 142, a third connecting frame 143, a rotating rod 144, a missing gear 145, a torsion spring 146, a connecting box 147, a connecting rod 148, a piston frame 149, a ventilation pipe 1410, a connecting cylinder 1411 and a third compression spring 1412. The first connecting frame 121 is connected to the second connecting frame 141 by bolts, and the second connecting frame 141 is rotatably connected to the full gear 142 on the side close to each other. The full gear 142 is connected to the rotating roller 122. The third connecting frame 143 is welded to the right side of the bottom of the bed board 6. The third connecting frame 143 is rotatably connected to the rotating rod 144. The rotating rod 144 and the third connecting frame 143 are symmetrically connected with a torsion spring 146. Both ends of the rotating rod 144 are connected to the missing gear 145, and the missing gear 145 is meshed with the adjacent full gear 142. A connecting box 147 is welded on the top, and a piston rack 149 is slidably connected to the connecting box 147. The piston rack 149 is in sealing contact with the connecting box 147. A connecting rod 148 is rotatably connected between the piston rack 149 and the rotating rod 144. The connection between the rotating rod 144 and the connecting rod 148 deviates from the axis of the rotating rod 144. A third compression spring 1412 is symmetrically connected between the piston rack 149 and the connecting box 147. Connecting tubes 1411 are symmetrically welded on the front and back sides of the bed board 6. A ventilation pipe 1410 is connected to the two connecting tubes 1411 on the same side and the connecting box 147. The compression frame 131 is slidably and sealedly connected to the adjacent connecting tubes 1411. When the piston rack 149 moves to the left, the piston rack 149 can squeeze the gas in the connecting box 147 into the ventilation pipe 1410 and the connecting tube 1411, thereby pushing the compression frame 131 to move upward, so that the compression frame 131 is separated from the medical film 123.

[0033] When the rotating roller 122 rotates counterclockwise, it drives the full gear 142 to rotate counterclockwise, and the missing gear 145 rotates clockwise under the action of meshing, driving the rotating rod 144 to rotate clockwise, the torsion spring 146 is deformed, and the connection between the rotating rod 144 and the connecting rod 148 deviates from the axis of the connecting rod 148, so that the rotating rod 144 pushes the connecting rod 148 to move to the left, driving the piston frame 149 to move to the left, the third compression spring 1412 is compressed, and the piston frame 149 can squeeze the gas in the connecting box 147 into the ventilation pipe 1410 and the connecting cylinder 1411, thereby pushing the pressing frame 131 to move upward, automatically making the pressing frame 131 and the medical device The film 123 is separated. When the missing gear 145 is not engaged with the full gear 142, the torsion spring 146 returns to its original state, driving the rotating rod 144 to rotate counterclockwise, thereby driving the missing gear 145 to rotate counterclockwise, and the missing gear 145 will engage with the full gear 142 again. In this reciprocating operation, the missing gear 145 will intermittently engage with the full gear 142, thereby causing the clamping frame 131 to reciprocate up and down to prevent the medical film 123 from being pressed by the clamping frame 131 when it is replaced. When the rotating roller 122 needs to be removed from the first connecting frame 121, the rotating roller 122 can be removed by manually loosening the bolts using tools, thereby replacing the medical film 123.
