Description

[0002] With the accelerating aging of the population, the demand for health checkups among the elderly continues to grow. As a core component of cardiovascular disease screening, the safety, convenience, and comfort of the electrocardiogram (ECG) examination process are particularly important for elderly examinees. The elderly generally experience declining limb mobility, weakened musculoskeletal function, and poor balance; some very elderly individuals also suffer from partial disability and slow movement. Traditional ECG examination beds are no longer adequate to meet their specific needs, gradually revealing numerous technical shortcomings.

[0003] In current electrocardiogram (ECG) examinations, the long multi-lead leads are prone to tangling and knotting during use and storage. Some methods use spring-loaded winding wheels to pull and wind the leads, which means that one end of the lead is always under tension from the winding wheel during use, affecting the stability of the electrode adsorption and thus interfering with the test results. Existing height-adjustable ECG examination beds have cumbersome operating procedures and are particularly unsuitable for the convenience and comfort needs of elderly people during physical examinations.

[0023] Working principle: Initial state as shown in the attached figure Figure 2 As shown, the bed board 2 is in the lowered state, and the adsorption electrode 4 and clamping electrode 5 are both located at the bottom of the device box 3. At this time, multiple sets of heaters 6 are located on both sides of the adsorption electrode 4 and clamping electrode 5. The electrodes can be preheated by existing methods such as light heating or warm air heating to reduce patient discomfort caused by excessive temperature difference. The fixing frame 38 has two sets located at the head and foot of the bed, respectively. The fixing frame 38 near the head of the bed is higher than the other fixing frame 38 to facilitate the identification of the head of the bed position. There are six sets of adsorption electrodes 4 evenly distributed near the head of the bed for adsorption detection on the patient's chest. There are four sets of clamping electrodes 5. Two sets are located in the middle of the device box 3 below for clamping detection on both wrists of the patient. The other two sets of clamping electrodes 5 are located near the foot of the bed for clamping detection on the patient's ankles. The clamping detection is performed by placing the electrodes in a relatively dispersed manner, which reduces the probability of wire 7 tangling during subsequent use and improves the winding and unwinding efficiency of wire 7 and the preheating efficiency of the electrodes. Two sets of conductive rods 12 are used to transmit data from the adsorption electrode 4 and the clamping electrode 5 to the detector 8. One set of conductive rods 12 has six sets of winding reels 9 on its side, and the other set of conductive rods 12 has four sets of winding reels 9 on its side. The six sets of winding reels 9 are connected to the six sets of wire 7 on the adsorption electrode 4 to receive the windings, and the four sets of winding reels 9 are connected to the four sets of wire 7 on the clamping electrode 5 to receive the windings. The winding direction of the wire 7 can be guided and controlled by the guide tube 39, so that the multiple sets of winding reels 9 can rotate synchronously and realize the winding and unwinding operation of multiple sets of wire 7 simultaneously.

[0024] When testing is required, the patient sits on the bed board 2 and lies flat with their head facing the head of the bed. Then, the scissor lift 37 is activated to slowly move the bed board 2 and the patient to the required height. During this process, the fixing block 25 moves upward synchronously with the bed board 2, reducing the tension on the tension spring 28. The tension spring 28 gradually contracts, and simultaneously, the tension on the connecting block 27 and the pull rope 23 decreases. The spring spring 35 rebounds in the opposite direction, driving the winding wheel 21 to rotate and wind up the pull rope 23. Simultaneously, the speed increaser 22 drives the belt pulley 18, and the two sets of... The pulley 18 drives the rotating rod 15 to rotate synchronously via the transmission belt 19. The rotating rod 15 drives the drive gear 16 to rotate the external gear ring 17. The external gear ring 17 drives the take-up reel 9 to rotate, gradually loosening the wire 7 from the take-up reel 9. The preheated adsorption electrode 4 and clamping electrode 5 gradually descend. During the upward movement of the connecting block 27, the inclined surface of the clamping block 31 is inclined upward, allowing it to slide against the outer wall of the inclined tooth groove 32. With the compression and rebound of the buffer spring 33, the upward movement of the connecting block 27 is not affected. When the bed board 2 moves to the required position... After placement, the adsorption electrode 4 and clamping electrode 5 are lowered to a position close to the patient's body for vertical suspension. Medical personnel then pull the adsorption electrode 4 and clamping electrode 5 one by one to fix them to their corresponding positions on the patient. The pulling of the lead wire 7 causes the winding reel 9 to continue rotating, which in turn causes the drive gear 16 to rotate the rotating rod 15 and the pulley 18. The pulley 18 then rotates the winding reel 21, which in turn causes the pull rope 23 to pull the connecting block 27 upwards. At this point, because the tension spring 28 is already in a state of low tension, the connecting block 27 is more easily... As the connecting block 27 continues to move upward, the locking block 31 continuously slides and locks in the locking groove, preventing the connecting block 27 from moving downward and pulling the wire 7 to rewind. This avoids the situation where the wire 7 continuously exerts tension on the adsorption electrode 4 during the fixing process, affecting the stability and accuracy of the detection. During this process, the spring 35 is always in the state of driving the wire 7 to be released from the rewinding reel 9. It is only under the tension of the tension spring 28 that the wire 7 can be released to a certain length. After that, medical personnel need to manually pull the wire 7.

[0025] After the test, medical staff release the fixation of the adsorption electrode 4 and clamping electrode 5 to the patient one by one. Pressing the button controls the electric telescopic rod 30 to pull back, causing the locking block 31 to move away from the locking groove and release the limiting state. Under the pull of the tension spring 28, the connecting block 27 moves down to the equilibrium position. At this time, the pull rope 23 drives the winding wheel 21 to rotate, causing the winding reel 9 to rewind the wire 7 for a further length, so that the adsorption electrode 4 and clamping electrode 5 return to the position close to the patient. At this time, the multiple sets of wires 7 are in a relatively vertical suspended state. Medical staff can perform preliminary sorting of the wires 7 according to their position to avoid tangling. This sorting is more efficient than when the wires 7 are longer, quickly separating the tangled wires 7 and allowing gravity to keep the multiple sets of wires 7 in a relatively vertical position, avoiding later... If tangling occurs during the winding process, the patient remains lying flat. Medical staff then control the scissor lift 37 to lower the bed board 2. The bed board 2 moves the fixing block 25, causing the tension spring 28 to pull the connecting block 27 downwards. The connecting block 27 pulls the pull rope 23, causing the winding wheel 21 to continue rotating. The fixing shaft 34 drives the spring 35 to continuously compress and store power. The pulley 18 and rotating rod 15 drive the winding reel 9 to simultaneously wind up multiple sets of wires 7. The adsorption electrode 4 and clamping electrode 5 are reset to a position near the bottom of the device box 3. The bed board 2 is also simultaneously lowered to the required position, allowing the patient to get off the bed board 2. Then, the electric telescopic rod 30 is controlled to push the buffer spring 33, causing the locking block 31 to contact the inner wall of the guide groove 26 again, completing the overall reset operation. Repeating the above operation allows for the ECG examination of the next patient requiring examination.

[0026] The device has a simple structure and is easy to operate. It can orderly wind up multiple sets of leads 7 while avoiding excessive tension on the leads 7, which would affect the stability of the test. This greatly improves the efficiency of the examination, makes it convenient for patients to get on and off, and reduces discomfort during the examination by preheating the electrodes, thus improving the accuracy of the test results.
