[0014] A method for using a patient limb protection and restraint device for an interventional catheterization laboratory comprises the following steps: Step 1: Before the operation, the angle of the movable bed can be adjusted by the electric push rod. When the electric push rod is started, it will push the movable bed to rotate; Step 2: The movable bed board rotates, which causes the push rod to move. When the movable bed board is flush with the fixed bed board, the side of the sliding plate close to the push rod does not contact the movable bed board; Step 3: When the movable bed board rotates to a certain angle, the sliding plate will slide along the inner wall of the sliding groove, and the sliding plate will push the push rod to slide, and the sliding of the push rod will push the pillow to move, so that the pillow is always under the patient's head to protect the patient's head.

[0015] The present invention provides a patient limb protection and restraint device for use in an interventional catheterization laboratory. It has the following beneficial effects: (1) In this invention, when the movable bed plate gradually rotates toward the fixed bed plate, the distance between the sliding plate and the rotating plate will gradually decrease, and the sliding plate and the rotating plate will push the support plate to move away from the fixed bed plate, and the support plate will lift the patient's waist to prevent the patient's waist from being in a suspended state during surgery. The support plate can lift the patient's waist to keep the patient's waist in a relaxed state during surgery and protect the patient's waist from injury. The movement of the rack will drive the inner rod to move away from the outer rod, and the movement of the inner rod will push the armrest to move, so that when the doctor adjusts the patient's body angle through the movable bed plate, the armrest will drive the patient's arm to a more comfortable position, avoiding a large adjustment angle of the movable bed plate when the patient's body is adjusted, which may cause the relative position between the arm and the armrest to change. If the armrest is not adjusted together, the arm may be excessively pulled or unnaturally twisted, causing discomfort or potential injury.

[0016] (2) In this invention, when it is necessary to fix the patient's arm, the drawer plate can be pulled to move. The movement of the drawer plate will drive the square block to move. The movement of the square block will lose contact with the inner wall of the slot. Pulling the drawer plate will release the limit on the sliding frame. The doctor can then adjust the position of the sliding frame so that the patient's arm is on the surface of the sliding frame, which can fix the patient's arm well and avoid the patient's arm being too long or too short so that the doctor cannot fix the arm well.

[0017] (3) In this invention, after adjusting the distance between the first arc-shaped clamp and the second arc-shaped clamp, the pin is pulled upward to move. When the pin moves upward, it will lose contact with the inside of the circular hole, and the limit of the fixed block will be released. After the limit of the fixed block is released, the doctor can move the position of the fixed block to control the final fixed position. By adjusting the distance between the first arc-shaped clamp and the second arc-shaped clamp, the thickness of the patient's arm can be adapted, so that the binding device can fix the patient's arm well, avoiding the binding device being tied too tightly to cause damage to the patient's arm, or being tied too loosely to prevent the patient's arm from being completely fixed.

[0018] (4) In this invention, when the elastic slider moves to the top of the elastic slider, the elastic slider will be pulled by the No. 8 spring to move toward the inner wall of the slider groove. When the elastic slider moves toward the inner wall of the slider groove, it will lose contact with the baffle, and the elastic slider will lose its obstruction to the baffle, and the limit of the pad will be released. Limiting the pad and the No. 1 arc-shaped cuff can avoid accidental contact before the binding device is tied to the arm, so that the distance between the No. 1 arc-shaped cuff and the pad is reduced, and the movable end of the No. 1 hydraulic device is squeezed, so that the reinforcement device is activated before the patient is tied.

[0019] (5) In this invention, when the fixing plate fits with the inner rod, the No. 3 torsion spring drives the rotating buckle to rotate, and the rotating buckle will contact the inner wall of the slot, so that the fixing plates on both sides fix the inner rod. The inner rod is fixed by the fixing plates to prevent the patient from struggling too violently and causing damage to the inner rod. When the patient struggles too violently, a large stress will be applied to the inner rod. When the stress is too large, it will cause a certain degree of deformation to the inner rod, making it impossible for the inner rod to return to the inner rod normally, causing certain property losses.

[0026] A method for using a patient limb protection and restraint device for an interventional catheterization laboratory comprises the following steps: Step 1: Before the operation, the angle of the movable bed plate 3 can be adjusted by the electric push rod 5. When the electric push rod 5 is started, it will push the movable bed plate 3 to rotate; Step 2: The movable bed board 3 rotates, causing the push rod 10 to move. When the movable bed board 3 is flush with the fixed bed board 2, the side of the sliding plate 11 close to the push rod 10 does not contact the movable bed board 3; Step 3: When the movable bed board 3 rotates to a certain angle, the sliding plate 11 will slide along the inner wall of the sliding groove, and the sliding plate 11 will push the push rod 10 to slide. The sliding of the push rod 10 will push the pillow 9 to move, so that the pillow 9 is always under the patient's head to protect the patient's head.

[0027] When the present embodiment is working, when it is necessary to perform surgery on the patient, the patient is first allowed to lie on the fixed bed board 2 and the movable bed board 3, and then the patient is allowed to rest his head on the pillow 9. After the patient lies down, the patient is tied up with the restraint belt 4 and the patient's hands are fixed on the top of the armrest 8 to prevent the patient from sliding down when the patient cannot support the body due to anesthesia during the operation. Before the operation, the angle of the movable bed board 3 can be adjusted by the electric push rod 5. When the electric push rod 5 is started, it will push the movable bed board 3 to rotate, and the rotation of the movable bed board 3 will drive the push rod 10 to move. When the fixed bed board 2 is flush, the side of the sliding plate 11 close to the push rod 10 does not contact the movable bed board 3. When the movable bed board 3 rotates to a certain angle, the sliding plate 11 will slide on the inner wall of the sliding groove, and the sliding plate 11 will push the push rod 10 to slide. The sliding of the push rod 10 will push the pillow 9 to move, so that the pillow 9 is always under the patient's head to protect the patient's head. The movement of the sliding plate 11 will contact the movable bed board 3. When the movable bed board 3 continues to rotate, the movable bed board 3 will push the sliding plate 11 to move toward the supporting plate 12. When the movable bed board 3 gradually moves towards the fixed bed board 2, the distance between the sliding plate 11 and the rotating plate 13 will gradually decrease, and the sliding plate 11 and the rotating plate 13 will push the supporting plate 12 to move away from the fixed bed plate 2, so that the supporting plate 12 will support the patient's waist, preventing the patient's waist from being in a suspended state during surgery. The supporting plate 12 supporting the patient's waist can keep the patient's waist in a relaxed state during surgery to protect the patient's waist from injury. When the movable bed plate 3 rotates, it drives the gear shaft 14 to rotate, and the rotation of the gear shaft 14 drives the transmission gear 15 to rotate. The rotation of the transmission gear 15 drives the rack 16 to move, and the movement of the rack 16 drives the inner rod 7 to move away from the outer rod 6. The movement of the inner rod 7 pushes the armrest 8 to move, so that the armrest 8 drives the patient's arm to a more comfortable position when the doctor adjusts the patient's body angle through the movable bed plate 3, avoiding a large adjustment angle of the movable bed plate 3 when the patient's body is adjusted, which may cause the relative position between the arm and the armrest 8 to change. If the armrest 8 is not adjusted together, the arm may be excessively pulled or unnaturally twisted, causing discomfort or potential injury.

[0033] When the embodiment is working, when the patient's arm needs to be fixed, the draw plate 24 can be pulled to move, and the movement of the draw plate 24 will drive the square block to move. The movement of the square block will lose contact with the inner wall of the slot, and then the draw plate 24 will release the limit of the sliding frame 20. The doctor can then adjust the position of the sliding frame 20 so that the patient's arm is on the surface of the sliding frame 20, which can fix the patient's arm well and avoid the patient's arm being too long or too short so that the doctor cannot fix the arm well. If the arm is too thin, the doctor can first press the button 29. When the button 29 is pressed, the curved plate 28 is pushed to move. The movement of the curved plate 28 drives the protrusion 291 to move. The movement of the protrusion 291 will lose contact with the limiting hole, and the limit of the second curved band 23 will be released. The doctor can pull the second curved band 23 toward the first curved band 21 to reduce the distance between the first curved band 21 and the second curved band 23, so that the first curved band 21 and the second curved band 23 can fit the patient's arm. After adjusting the first curved band 21, the doctor can adjust the second curved band 23 to fit the patient's arm. When the distance between the first and second curved straps 21 and 23 is adjusted, the latch 27 is pulled upwards. The latch 27 loses contact with the inside of the circular hole when moving upwards, and the limit of the fixing block 25 is released. When the limit of the fixing block 25 is released, the doctor can move the position of the fixing block 25 to control the final fixed position. When the position is fully adjusted, the fixing key is inserted into the inner wall of the fixing groove. After the fixing key is inserted into the fixing groove, it contacts the inclined surface of the fixing pin 26, and the fixing key pushes the fixing pin 26 to move away from the fixing block 25. When the fixing key is fully inserted, the fixing pin 26 is pulled back to its original position by the fourth spring, so that the fixing pin 26 contacts the top of the fixing key to limit the fixing key, and the fixing pin 26 also limits the second curved strap 23. By adjusting the distance between the first and second curved straps 21 and 23, the thickness of the patient's arm can be adapted, so that the binding device can fix the patient's arm well, avoiding the binding device being tied too tightly to cause damage to the patient's arm, or being tied too loosely to prevent the patient's arm from being completely fixed.

[0034] When the No. 1 curved band 21 is rotated to fix the arm, the rotation of the No. 1 curved band 21 will drive the curved block 32 to move. When the curved block 32 moves, the inclined surface of the curved block 32 will contact the pushing block 35, and the pushing block 35 will push the curved block 32 to move toward the elastic slider 33. The movement of the curved block 32 will drive the slider groove to move. When the binding device completely fixes the patient's arm, the curved block 32 will drive the slider groove to move above the elastic slider 33. When the elastic slider 33 moves above the elastic slider 33, the elastic slider 33 will be pulled by the No. 8 spring to move toward the inner wall of the slider groove. When the elastic slider 33 moves toward the inner wall of the slider groove, it will lose contact with the baffle 34, and the elastic slider 33 will lose its obstruction to the baffle 34, and the limit of the pad 31 will be released. If the patient is The arm 37 of the patient is tightened and the support 23 is tightened, and the support 23 is tightened. When the movable end moves toward the inner wall of the No. 1 hydraulic device 30, the upward movement of the pad 31 will squeeze the liquid inside the No. 1 hydraulic device 30 into the No. 2 hydraulic device 38 through the hose. When the liquid inside the No. 2 hydraulic device 38 increases, the liquid will squeeze the output end of the No. 2 hydraulic device 38 to move away from the No. 2 hydraulic device 38. The movement of the output end of the No. 2 hydraulic device 38 will push the long plate 393 to move. The movement of the long plate 393 will drive the limit block to move. The movement of the limit block will lose contact with the limit groove. The movement of the limit block will release the limit on the rotating plate 39. The rotating plate 39 will be driven by the No. 2 torsion spring to rotate. The No. 2 torsion spring will drive the rotating plate 39 to rotate in the direction of the inner rod 7. The rotation of the rotating plate 39 will drive the fixed plate 391 to move. The fixed plate 391 The movement will fix the inner rod 7, and the rotation of the fixing plate 391 will drive the rotating buckle 392 to move. The movement of the rotating buckle 392 will contact the fixing plate 391 on the other side, and the fixing plate 391 will push the rotating buckle 392 to rotate. When the fixing plate 391 is in contact with the inner rod 7, the No. 3 torsion spring will drive the rotating buckle 392 to rotate, and the rotating buckle 392 will contact the inner wall of the slot, so that the fixing plates 391 on both sides fix the inner rod 7. The inner rod 7 is fixed by the fixing plate 391 to prevent the patient from struggling too violently and causing damage to the inner rod 7. When the patient struggles too violently, a greater stress will be applied to the inner rod 7. When the stress is too great, a certain degree of deformation will be caused to the inner rod 7, making it impossible for the inner rod 7 to return to the inside of the outer rod 6 normally, causing certain property losses.
