[0001] The present invention relates to the technical field of electrocardiogram equipment, and in particular to an anti-interference electrocardiogram examination device. Background Art
[0002] In order to monitor and evaluate the health status and disease development of patients, it is necessary to regularly examine and record relevant data during the rehabilitation process of chronic disease patients. This process involves collecting, sorting, and analyzing a series of medical data related to chronic diseases, aiming to help doctors formulate more accurate treatment plans, optimize rehabilitation plans, and timely adjust treatment plans to address possible problems. An electrocardiograph can provide important information about heart function, which is crucial for evaluating the heart condition of chronic disease patients.
[0003] During the use of an electrocardiograph, there are often many wires. If the wires are bent or twisted, it may cause noise interference or signal attenuation, resulting in the distortion of the electrocardiogram waveform.

One end of the horizontal cavity is fixedly connected to one side of the support frame, and the vertical cavity is fixedly connected to one side of the support frame and is located below the horizontal cavity; A plurality of circular cavities are slidably connected to the upper side wall of the vertical cavity. The upper end of the circular cavity is fixedly connected to a concave plate, the lower end of the circular cavity is fixedly communicated with an inflatable bag, one end of the concave plate away from the circular cavity is rotatably connected to a guide wheel, and a combing component is installed on the horizontal cavity. The combing component includes a moving cavity, a telescopic rod, and a limiting plate. A plurality of moving cavities are all slidably connected to the horizontal cavity. Sliding grooves are provided on both the horizontal cavity and the moving cavity. One end of each of the plurality of telescopic rods is rotatably connected to the moving cavity through a rotating shaft, and a plurality of limiting plates are respectively fixedly connected to one end of the moving cavity. A plug rod is fixedly connected to the telescopic rod; A pressing plate is slidably connected in the chute. One end of the pressing plate is slidably connected in the moving cavity, and a pulling plate is hinged between the other end and the rotating shaft. An air delivery pipe is fixedly connected between the moving cavity and the telescopic rod.
[0006] Preferably, the carding component further includes a connecting pipe, a square cavity, and a piston plate. A plurality of the square cavities are fixedly connected to the support frame. One end of the piston plate is slidably connected in the square cavity. The connecting pipe is fixedly communicated between the square cavity and the circular cavity. One end of the piston plate away from the square cavity is slidably connected to the limiting plate. A torsion spring is fixedly connected between the rotating shaft and the moving cavity.
[0007] Preferably, a plurality of mounting grooves are installed in the transverse cavity. A cylinder is fixedly connected in the mounting groove. A conical block is slidably connected in the cylinder. One end of the cylinder is fixedly communicated with a sleeve. A return spring is arranged between the conical block and the inner wall of the cylinder. One end of the conical block is fixedly connected with a cylinder, and the cylinder slides in the sleeve.
[0008] Preferably, a support rod is slidably connected to the upper side wall of the cylinder. One end of the support rod away from the cylinder passes through the transverse cavity, and the support rod is fixedly connected with a protective plate. One end of the cylinder is fixedly communicated with a spray pipe, and a one-way valve is installed on the spray pipe.
[0009] Preferably, two grooves are formed in the support frame. Clamping plates are respectively slidably connected in the two grooves. A sliding cavity is slidably connected to the clamping plate. A straight spring is fixedly connected between the inner wall of the sliding cavity and the clamping plate.
[0010] Preferably, a measuring instrument is installed between the two clamping plates. A plurality of wires are inserted into the measuring instrument. One end of the wire away from the measuring instrument is fixedly connected to one end of the telescopic rod.
[0011] Preferably, a lead screw is rotatably connected to the support frame. The two clamping plates are respectively threadedly connected to both ends of the lead screw.
[0012] Preferably, one end of the support rod away from the protective plate is slidably connected to the outer side wall of the conical block.
[0013] Preferably, a plurality of through grooves are formed in the upper end of the support frame. A plurality of the limiting plates are respectively slidably connected in the through grooves.
[0014] Preferably, a plurality of drawers are arranged in the support frame, and the vertical cavity is filled with water.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. During the movement of the splint in the middle position, the sliding cavity contacts the measuring instrument. As the splint continues to move, when the sliding cavity is restricted by the measuring instrument and stops moving, it can stretch the straight spring. Therefore, the clamping effect on the measuring instrument is achieved by using the pulling force of the straight spring on the sliding cavity to ensure the stability of the measuring instrument during use.
[0016] 2. As the gas in the inflatable bag increases, it expands. The expanded inflatable bag generates buoyancy in the water in the vertical cavity and pushes the cylinder, concave plate, and guide wheel upward. At this time, the wire wound around the guide wheel becomes loose and is no longer taut, facilitating the end of the wire to fit against the human body for measurement.
[0017] 3. Since the wire is inside the telescopic rod, and the telescopic rod can be made of anti-interference material. When it extends, the wire is inside the telescopic rod at this time, thus achieving the effect of separating multiple wires, avoiding entanglement and crossing of multiple wires, reducing interference between each other, and improving the signal transmission quality.
[0018] 4. After the gas inside the inflatable bag flows back into the square cavity, the buoyancy of the inflatable bag decreases. Under the gravity of the concave plate, it moves downward and resets together with the inflatable bag and the circular cavity. As the concave plate and the guide wheel move downward, the wire can be pulled again and tightened. During the process of the wire being tightened, the telescopic rod can be pulled to contract, achieving the effect of automatically tightening the wire and avoiding entanglement and excessive bending between the wires.
[0019] 5. As the moving cavity resets, one end of the wire is under the protective plate. At the same time, the insertion rod slides into the sleeve and pushes the cylinder and the conical block to move in the cylinder. The conical block can squeeze the disinfectant water in the cylinder to spray out through the spray pipe to the end of the wire in contact with the human body for disinfecting the wire.

Detailed implementation manners
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0023] Refer to Figures 1 - 10 , an anti-interference electrocardiogram examination device, the anti-interference electrocardiogram examination device includes a support frame 1, a transverse cavity 7 and a vertical cavity 12. One end of the transverse cavity 7 is fixedly connected to one side of the support frame 1, and the vertical cavity 12 is fixedly connected to the side of the support frame 1 below the transverse cavity 7. The vertical cavity 12 is arranged in a concave shape. A plurality of drawers are provided in the support frame 1, and the drawers can place the components of the detection device. The vertical cavity 12 is filled with water.
[0024] A plurality of circular cavities 19 are slidably connected to the upper side wall of the vertical cavity 12. A concave plate 13 is fixedly connected to the upper end of the circular cavity 19. The lower end of the circular cavity 19 is fixedly communicated with an inflatable bag 18. The inflatable bag 18 is stretchable and will expand when filled with gas, increasing the buoyancy in water. When the gas inside the inflatable bag 18 is discharged, the buoyancy decreases. One end of the concave plate 13 away from the circular cavity 19 is rotatably connected to a guide wheel 14. The downward movement of the guide wheel 14 can pull the wire 11 and has a tightening effect on the wire 11. A combing component is installed on the transverse cavity 7. The combing component includes a moving cavity 10, a telescopic rod 9, and a limiting plate 17. The middle part of the limiting plate 17 is inclined and the two ends are horizontal. When the limiting plate 17 moves and the inclined surface slides onto the piston plate 16, it can squeeze the piston plate 16 to move downward. A plurality of moving cavities 10 are all slidably connected to the transverse cavity 7. Chute grooves are opened on both the transverse cavity 7 and the moving cavity 10. One end of each of the plurality of telescopic rods 9 is rotatably connected to the moving cavity 10 through a rotating shaft 23. The inside of the telescopic rod 9 is hollow. The wire 11 passes through one end of the telescopic rod 9 and exits from the other end. At the same time, the wire 11 is fixedly connected to one end of the telescopic rod 9. Therefore, when the gas inside the telescopic rod 9 increases, it can elongate and drive the wire 11 to move, facilitating the staff to adsorb the wire 11 on the human body. A plurality of limiting plates 17 are respectively fixedly connected to one end of the moving cavity 10. A plug rod 32 is fixedly connected to the telescopic rod 9. When the plug rod 32 enters the sleeve 25, it can limit the telescopic rod 9. A plurality of through grooves are opened at the upper end of the support frame 1. A plurality of limiting plates 17 are respectively slidably connected in the through grooves.
[0025] The combing component further includes a connecting pipe 2, a square cavity 15, and a piston plate 16. A plurality of square cavities 15 are all fixedly connected to the support frame 1. One end of the piston plate 16 is slidably connected inside the square cavity 15. The connecting pipe 2 is fixedly communicated between the square cavity 15 and the circular cavity 19. The end of the piston plate 16 away from the square cavity 15 is slidably connected to the limiting plate 17. When the limiting plate 17 no longer squeezes the piston plate 16 and the gas inside the inflatable bag 18 flows back into the square cavity 15, it can push the piston plate 16 to move upward and reset. A torsion spring 21 is fixedly connected between the rotating shaft 23 and the moving cavity 10.
[0026] A pressing plate 20 is slidably connected in the chute groove. One end of the pressing plate 20 is slidably connected inside the moving cavity 10. One end of the pressing plate 20 is slidably connected to the inner wall of the moving cavity 10. When the pressing plate 20 moves, it can squeeze the gas inside the moving cavity 10. The other end is hinged to a pulling plate 24 with the rotating shaft 23. The torsion spring 21 can drive the rotating shaft 23 and the telescopic rod 9 to flip. An air delivery pipe 22 is fixedly connected between the moving cavity 10 and the telescopic rod 9.
[0027] A plurality of mounting grooves are installed in the transverse cavity 7. A cylinder 26 is fixedly connected in the mounting groove. A conical block 28 is slidably connected in the cylinder 26. One end of the cylinder 26 is fixedly communicated with a sleeve 25. A return spring is provided between the conical block 28 and the inner wall of the cylinder 26. One end of the conical block 28 is fixedly connected with a cylinder 31. The cylinder 31 slides in the sleeve 25. The conical block 28 can squeeze the disinfectant water in the cylinder 26 into the spray pipe 29 and atomize the disinfectant water to spray it on the end of the wire 11 to disinfect the part where the wire 11 contacts the human body. A support rod 27 is slidably connected to the upper side wall of the cylinder 26. One end of the support rod 27 away from the protection plate 8 is slidably connected to the outer side wall of the conical block 28. One end of the support rod 27 away from the cylinder 26 passes through the transverse cavity 7, and the support rod 27 is fixedly connected with a protection plate 8. The protection plate 8 has a protection effect on the end of the wire 11 and can reduce the diffusion of the disinfectant water sprayed by the spray pipe 29 to ensure that the disinfectant water sprayed by the spray pipe 29 is sprayed on the end of the wire 11 as much as possible for disinfection. One end of the cylinder 26 is fixedly communicated with a spray pipe 29, and a one-way valve is installed on the spray pipe 29.
[0028] Two grooves are formed in the support frame 1. Clamping plates 5 are respectively slidably connected in the two grooves. A sliding cavity 4 is slidably connected to the clamping plate 5. A straight spring 30 is fixedly connected between the inner wall of the sliding cavity 4 and the clamping plate 5. A measuring instrument 6 (the measuring instrument 6 is an electrocardiogram measuring device in the prior art and will not be explained in detail here) is installed between the two clamping plates 5. A plurality of wires 11 are inserted into the measuring instrument 6. One end of the wire 11 is electrically connected to the measuring instrument 6, and the other end is adsorbed to the human body to be detected. One end of the wire 11 away from the measuring instrument 6 is fixedly connected to one end of the telescopic rod 9. A lead screw 3 is rotatably connected to the support frame 1. The two clamping plates 5 are respectively threadedly connected to both ends of the lead screw 3. When the lead screw 3 rotates, it can drive the two clamping plates 5 to move centrally. When the lead screw 3 rotates in the reverse direction, it can drive the two clamping plates 5 to move away from each other.
[0029] In the present invention, during use, first place the measuring instrument 6 on the upper end of the support frame 1 and between the two clamping plates 5. Then rotate one end of the lead screw 3. The rotation of the lead screw 3 can drive the two clamping plates 5 to move centrally. During the central movement of the clamping plate 5, the sliding cavity 4 contacts the measuring instrument 6. As the clamping plate 5 continues to move, when the sliding cavity 4 is limited by the measuring instrument 6 and no longer moves, it can stretch the straight spring 30, and use the pulling force of the straight spring 30 on the sliding cavity 4 to achieve the clamping effect on the measuring instrument 6 to ensure the stability of the measuring instrument 6 during use.
[0030] Then, one end of the wire 11 is inserted into the measuring instrument 6, and the other end bypasses the guide wheel 14 and is fixedly connected to the end of the telescopic rod 9 far from the moving cavity 10. When the wire 11 needs to be connected to the human body, first pull the moving cavity 10 to move away from the support frame 1. Since the lower end of the limiting plate 17 is arranged as an inclined surface, when the limiting plate 17 moves with the moving cavity 10, it can squeeze the piston plate 16 to move downward in the square cavity 15, and compress the gas in the square cavity 15 to enter the circular cavity 19 through the connecting pipe 2, and enter the inflatable bag 18 through the circular cavity 19. The inflatable bag 18 expands as the gas increases. The buoyancy of the inflated inflatable bag 18 in the water in the vertical cavity 12 increases, and pushes the cylinder 19, the concave plate 13 and the guide wheel 14 to move upward. At this time, the wire 11 wound around the guide wheel 14 becomes loose and is no longer taut. At the same time, when the insertion rod 32 moves with the moving cavity 10 and disengages from the sleeve 25 on the transverse cavity 7, when the insertion rod 32 and the telescopic rod 9 are no longer limited by the sleeve 25 on the transverse cavity 7, the telescopic rod 9 and the rotating shaft 23 rotate from the inclined state to the horizontal state under the reset of the torsion spring 21. Since the rotating shaft 23 is arranged in an L shape, after rotation, the pressing plate 20 is pulled to move in the moving cavity 10 through the pull plate 24, and the gas in the moving cavity 10 is squeezed into the telescopic rod 9 through the air delivery pipe 22. The telescopic rod 9 elongates due to the increase of gas inside. The end of the telescopic rod 9 far from the moving cavity 10 pulls the loose wire 11 to move, so that the end of the wire 11 can be attached to the human body for measurement. Since the wire 11 is inside the telescopic rod 9, the effect of separating multiple wires 11 is achieved, avoiding winding and crossing of multiple wires 11 during use, reducing interference between each other, and thus improving the signal transmission quality.
[0031] When the detection is completed, push the moving cavity 10 to reset. At this time, when the limiting plate 17 moves with the moving cavity 10, it no longer squeezes the piston plate 16. Since the inflatable bag 18 has elasticity, at this time, the inflatable bag 18 contracts and the internal gas flows back to the square cavity 15 through the circular cavity 19 and the connecting pipe 2, and pushes the piston plate 16 to move upward and reset. At this time, after the internal gas of the inflatable bag 18 flows back to the square cavity 15, the buoyancy of the inflatable bag 18 is less. Therefore, under the gravity of the concave plate 13, it moves downward and resets together with the inflatable bag 18 and the circular cavity 19. As the concave plate 13 and the guide wheel 14 move downward, the wire 11 can be pulled again, and the wire 11 is tightened. As the wire 11 is tightened, the telescopic rod 9 can be pulled to contract, achieving the effect of automatically tightening the wire 11, avoiding winding and bending of the wires 11 and causing damage, and at the same time being able to complete the automatic arrangement of the wires 11 to ensure that each wire 11 can be placed in an orderly manner.
[0032] While pushing the telescopic rod 9 in the horizontal state and turning it to the inclined state, when the moving cavity 10 is reset, one end of the wire 11 is located under the protection plate 8. At the same time, the insertion rod 32 slides into the sleeve 25 and pushes the cylinder 31 and the conical block 28 to move in the cylinder 26, connecting the cylinder 26 with the external disinfection box. As the conical block 28 moves in the cylinder 26 and compresses the return spring, the one-way valve at the connection between the cylinder 26 and the external disinfection box closes, and the one-way valve on the spraying pipe 29 opens. The conical block 28 can squeeze the disinfection water in the cylinder 26 to spray out through the spraying pipe 29 to the end of the wire 11 in contact with the human body, disinfecting the wire 11. If it is used again, when the moving cavity 10 is pulled out and the insertion rod 32 no longer squeezes the cylinder 31, the cylinder 31 and the conical block 28 are reset and move under the push of the return spring. At this time, the one-way valve at the connection between the cylinder 26 and the external disinfection box opens, and the one-way valve on the spraying pipe 29 closes. The disinfection water in the external disinfection box can flow into the cylinder 26 to prepare for disinfecting the retracted wire 11 again.
[0033] As described above, only the preferred specific embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
