DETAILED DESCRIPTION

[0029] like Figure 1-3 , 10-11, a colonoscopy screening bed with an auxiliary abdominal pressurizer, comprising a bed board 1 and a clamping mechanism arranged on one side of the bed board 1, through which the patient's legs can be locked on the bed board 1, so as to facilitate the medical staff to perform colonoscopy;

[0030] Further, the clamping mechanism includes an upper clamping plate 3 and a lower clamping plate 5, and the upper clamping plate 3 and the lower clamping plate 5 are connected by a telescopic assembly. Specifically, the telescopic assembly includes a slide bar 7 hinged to the upper clamping plate 3 and a rod sleeve 8 hinged to the lower clamping plate 5. One end of the slide bar 7 away from the upper clamping plate 3 extends into the rod sleeve 8 and slidably cooperates with the slide bar 7. The rod sleeve 8 is provided with a limit assembly that cooperates with the slide bar 7.

[0031] A Velcro 301 is fixedly provided on the upper splint 3, and the patient's thigh can be fixed to the upper splint 3 through the Velcro 301, and a connecting belt 502 is fixedly provided on the lower splint 5. In actual use, the patient first sits on the side of the bed board 1 so that the thigh is located on the upper splint 3, and the thigh is locked by the Velcro 301, while the calf is aligned with the lower splint 5, and the patient's calf is locked to the lower splint 5 by the connecting belt 502. When the patient bends his knees and lies on his side on the bed board 1, one end of the connecting belt 502 is fixed to the side of the bed board 1, so that the lower splint 5 can remain stable relative to the bed board 1, and when the patient lies on his side, the sliding rod 7 and the rod sleeve 8 can be locked by the limiting assembly, thereby positioning the patient's leg.

[0032] like Figure 2-9 As shown, in actual use, the limit assembly includes a connecting block 9 elastically connected to the rod sleeve 8, the connecting block 9 is circular, and the end surface of the connecting block 9 close to the rod sleeve 8 protrudes downward to form a plug-in portion 902, and a plug-in groove 701 matching the plug-in portion 902 is opened on one side surface of the sliding rod 7 close to the plug-in portion 902, and a collar 10 is sleeved on the outer side of the plug-in portion 902, and the collar 10 is set in a T-shape, and the collar 10 and the rod sleeve 8 can be rotatably matched through a bearing, and a first magnetic plate 901 is fixedly installed on the end surface of the connecting block 9 close to the collar 10, and a second magnetic plate 1001 matching the first magnetic plate 901 is fixedly arranged on the end surface of the collar 10 close to the connecting block 9. In the initial state, the first magnetic plate 901 and the second magnetic plate 1001 are staggered with each other, and the first magnetic plate 901 and the second magnetic plate 1001 have different magnetic poles on the opposite sides;

[0033] An annular plate is sleeved on the outer side of the collar 10, and the annular plate is fixedly connected to the rod sleeve 8. A coil spring 13 is sleeved on the outer side of the collar 10, and the two ends of the coil spring 13 are respectively fixedly connected to the inner wall of the annular plate and the outer wall of the collar 10;

[0034] Furthermore, a slider 15 is slidably mounted on the lower clamping plate 5 that cooperates with the rod sleeve 8. Figure 8 As shown, the slider 15 is elastically matched with the lower clamping plate 5, and a traction rope 6 is fixedly arranged between the slider 15 and the ring 10. Figure 5 as well as Figure 8 As shown, a pin 14 is fixedly provided at one end of the rod sleeve 8 close to the lower clamping plate 5, and a base rotatably matched with the pin 14 is fixedly provided on the lower clamping plate 5, and one end of the above-mentioned traction rope 6 is fixedly connected to the outer circumferential surface of the ring 10, and a section of the traction rope 6 close to the ring 10 is wrapped around the outside of the ring 10, and the other end of the traction rope 6 extends to the pin 14 and passes through the pin 14 along the axial direction of the pin 14, and one end of the traction rope 6 passing through the pin 14 extends into the lower clamping plate 5 and is fixedly connected to the slider 15, and the above-mentioned traction rope 6 is slidably matched with the rod sleeve 8, the pin 14 and the lower clamping plate 5.

[0035] In the initial state, the clamping mechanism is hung on one side of the bed. When in use, the patient sits on one side of the bed, and the patient's two legs are placed on the clamping mechanisms on the left and right sides respectively. The patient's thigh is fixed to the upper splint 3 by the Velcro 301, and the patient's calf is initially locked to the lower splint 5 by the connecting belt 502. Then the patient is allowed to lie on his side with his knees bent. When the patient lies on his side with his legs together, the lower splint 5 and the upper splint 3 at the two clamping structures will fit each other, and when the patient lies on his side, the slider 15 on the lower splint 5 is changed from a horizontal state to a vertical state. At this time, the slider 15 will move downward relative to the lower splint 5 under the action of gravity. In this process, the slider 15 can pull the traction rope 6, thereby driving the ring 10 to rotate through the traction rope 6, so that the second magnetic plate 1001 on the ring 10 is aligned with the first magnetic plate 901 on the connecting block 9. The suction force between plate 901 and the second magnetic plate 1001 can drive the connecting block 9 to move downward, so that the plug-in portion 902 on the connecting block 9 can move toward the direction of the sliding bar 7, and when the plug-in portion 902 is inserted into the plug-in slot 701 on the sliding bar 7, the sliding bar 7 and the rod sleeve 8 are locked with each other, so that the angle between the patient's thigh and calf cannot be adjusted. During the period when the plug-in portion 902 and the plug-in slot 701 are matched, the medical staff has sufficient time to adjust the patient's leg posture, and after the adjustment, the medical staff does not need to perform other operations, and only needs to wait for the plug-in portion 902 to be inserted into the plug-in slot 701 to lock the sliding bar 7. In order to further lock the patient's legs on the bed, one end of the connecting belt 502 can be fixed to the bed. At this point, the patient's legs are locked on the bed, which is beneficial for medical staff to perform colonoscopy.

[0036] In summary, this device sets two sets of clamping mechanisms on one side of the bed board 1. When the patient sits on one side of the bed board 1, the patient's legs can be fixed to the upper splint 3 and the lower splint 5 by using the connecting belt 502 and the Velcro 301. When the patient lies flat on the bed board 1, the sliding bar 7 and the rod sleeve 8 are in a sliding cooperation relationship. At this time, the patient's legs can be bent freely. When the patient adjusts his posture and bends his knees and lies on his side, the plug-in part 902 can gradually move downward and insert into the plug-in groove 701, so that the sliding bar 7 and the rod sleeve 8 are locked with each other. At this time, the patient's legs are in an unbendable state, so that the patient's legs can remain stable during the examination. After that, the connecting belt 502 can be used to further lock the patient's legs on the bed board 1. The overall operation is relatively convenient and does not require excessive operation by medical staff. In addition, this device can maximize the integrity of the bed board 1 structure when in use, so that a disposable spacer can be laid on the surface of the bed board 1 during the examination, making the overall examination more hygienic.

[0037] like Figure 5-9As shown, as a further development of the above scheme, the two lower clamping plates 5 can be matched with each other on opposite sides through a positioning unit. Specifically, the positioning unit includes a positioning block 1501 fixedly connected to one of the sliders 15. The positioning block 1501 can be provided in plurality. The positioning block 1501 passes through the lower clamping plate 5 and slidably cooperates with it. A plurality of positioning holes 501 are provided on the side of the other lower clamping plate 5 close to the positioning block 1501. The cross section of the positioning hole 501 is provided in a T-shape.

[0038] A pull rod 18 is elastically mounted on the slider 15, and a clamping block 16 is elastically mounted on the outer peripheral surface of the positioning block 1501. A pull rope 17 is fixedly mounted between the clamping block 16 and the pull rod 18. The pull rope 17 passes through the positioning block 1501 and slidably cooperates with the positioning block 1501.

[0039] In specific application, the positioning block 1501 can be installed on the lower splint 5 that matches the patient's left leg, and the positioning hole 501 is opened on the lower splint 5 that matches the patient's right leg. When the patient bends his knees and lies on his side to the right, the lower splint 5 on the patient's left leg will be placed above the lower splint 5 on the right leg, and the two lower splints 5 fit each other. In the process of the patient bending his knees and lying on his side, the slider 15 and the pull rod 18 are changed from horizontal to vertical. Under the influence of gravity, the pull rod 18 is relative to the positioning block 150 1 moves downward, so that the block 16 can pop out relative to the positioning block 1501. As the slider 15 moves downward, the positioning block 1501 will be inserted into the positioning hole 501, so that the two lower splints 5 can be locked. In addition, when the block 16 is inserted into the positioning hole 501, the block 16 can pop out and cooperate with the positioning hole 501. At this point, the patient's legs are locked, so that the patient's legs can remain stable in the horizontal and vertical directions, which is conducive to examining the patient.

[0040] To sum up, in this device, the patient's thigh and calf are first locked by the limiting assembly between the sliding rod 7 and the rod sleeve 8, so that the patient's legs cannot be bent, and then the patient's legs can be locked by the cooperation between the positioning block 1501 and the positioning hole 501, which can further improve the stability of the patient's legs on the bed board 1. When the patient's leg posture needs to be adjusted, the connecting belt 502 can be untied to release the lock between the patient's legs and the bed board 1, and the overall operation is relatively convenient.

[0041] like Figure 1As shown, a supporting leg is fixedly provided at the bottom of the bed board 1, a pressing plate 2 is provided on the side of the bed board 1 away from the clamping mechanism, a U-shaped connecting rod is fixedly provided on the pressing plate 2, a boss is fixedly provided at the bottom of the bed board 1, the connecting rod passes through the boss and slides with the boss, and a hydraulic rod is fixedly provided at the bottom of the bed board 1, the telescopic end of the hydraulic rod is fixedly connected to the connecting rod, and the pressing plate 2 can be automatically controlled through this structure to apply pressure to the patient's abdomen. Of course, the pressing plate 2 can also be manually controlled during specific use.

[0042] like Figure 1-3 As shown in 10-11, the upper splint 3 and the lower splint 5 are both configured to be L-shaped as a whole, and the opposite sides of the upper splint 3 and the lower splint 5 are provided with a through groove, and a limiting rod 19 is fixedly provided at the through groove; the two ends of the Velcro 301 are respectively provided with a furry surface 3011 and a hook surface 3012. During specific application, the Velcro 301 is attached to the patient's thigh, and the end of the Velcro 301 with the hook surface 3012 is passed around the outside of the limiting rod 19 and then bonded to the furry surface 3011 at the other end of the Velcro 301, so as to fix the patient's thigh on the upper splint 3.

[0043] There are many ways to fix the bed board 1 and the connecting belt 502. One implementation method is given here. Specifically, the end of the connecting belt 502 away from the lower splint 5 can also be set to a hook surface structure, and the bottom surface of one side of the bed board 1 is fixedly installed with a lower hanging 4, and the lower hanging 4 is provided with a bonding surface 401 that matches the connecting belt 502. The bonding surface 401 is a rough surface structure. In actual use, when the patient bends his knees and lies on his side on the bed board 1, the patient's calf can be placed on the side of the bed board 1 close to the lower hanging 4, and then, one end of the connecting belt 502 is passed around the limit rod 19 and bonded to the lower hanging 4.

[0044] like Figure 3-5 As shown, a connecting hole is provided on one side of the lower clamping plate 5 close to the bed board 1, and a hook matching the connecting hole is fixedly provided on the bed board 1. This structure facilitates hanging the clamping mechanism on one side of the bed board 1.

[0045] A base is fixedly mounted on the upper clamping plate 3, and one end of the slide rod 7 away from the rod sleeve 8 is rotatably matched with the base. A pulley is fixedly mounted on the base, and the traction rope 6 is passed around the outside of the pulley.

[0046] A slide plate 11 is fixedly sleeved on the outside of the connecting block 9, and guide rods 12 are arranged at both ends of the slide plate 11. The guide rod 12 is arranged in a T shape as a whole. The guide rod 12 passes through the slide plate 11 and slides with it, and a support spring is sleeved on the outside of the guide rod 12, and the support spring is located between the slide plate 11 and the rod sleeve 8.

[0047] like Figure 8As shown, the lower clamping plate 5 is provided with a sliding groove that slidably cooperates with the slider 15, and a first spring is fixedly arranged between the inner bottom surface of the sliding groove and the slider 15, and a circular hole that slidably cooperates with the pull rod 18 is provided at the junction of the slider 15 and the positioning block 1501, and a second spring is arranged between the inner bottom end of the circular hole and the pull rod 18, and a groove that slidably cooperates with the clamping block 16 is provided on the outer circumferential surface of the positioning block 1501, and a spring is fixedly arranged between the inner end surface of the groove and the clamping block 16. In actual use, the outer diameter of the positioning block 1501 can be smaller than the inner diameter of the positioning hole 501, which is conducive to inserting the positioning block 1501 into the positioning hole 501.

[0048] Reference Figure 3 In this solution, a limiting assembly is provided between the two groups of rod sleeves 8 and the sliding rod 7. However, in specific applications, a limiting assembly may be provided only between the upper sliding rod 7 and the rod sleeve 8.
