TECHNICAL FIELD

[0001] The present application relates to the technical field of auxiliary devices for electrocardiogram clinical examination, in particular to an auxiliary device for electrocardiogram clinical examination. BACKGROUND

[0002] An auxiliary device for electrocardiogram clinical examination aims to improve the convenience and operation efficiency in the process of electrocardiogram examination. Electrocardiogram is an important examination method for assessing the health status of the heart by collecting the electrical activity signals of the human heart through electrodes. In order to ensure the accuracy and comfort of the examination results, the auxiliary device is usually designed to help the clinician fix the electrodes and manage the cables more easily. Common auxiliary devices include electrode fixation supports, cable management systems, patient comfort pads, and adjustment devices, etc. The working principle of such auxiliary devices is usually to fix the electrodes through a series of cleverly designed supports or brackets to reduce the deviation or sliding of the electrode position. At the same time, the cable management system keeps the electrode cables neat and avoids entanglement. The supports or brackets can help fix the electrodes at different positions on the patient's body to ensure the accuracy of each examination. The cable management system can guide the electrode cables to distribute along the predetermined path to avoid the messy or bundled phenomenon of the cables during the examination process, thereby reducing the interference of the cables with the collection of electrocardiogram signals. In addition, the auxiliary device usually considers the comfort of the patient and is designed to be ergonomically shaped to help the patient maintain a comfortable posture and reduce discomfort during the long examination process.

[0003] However, the existing electrocardiogram examination auxiliary devices still have some problems in actual use, especially in the management of electrode cables. The electrode cables are prone to form entanglements or adhere to the surface of the patient's body. Especially when the patient needs to move or adjust the posture, the entanglement of the cables will not only cause the change of the electrode position, thereby affecting the accuracy of the electrocardiogram, but also if the cables adhere to the surface of the patient's skin, it may cause unclear or interference in signal collection, thereby affecting the subsequent examination effect. Therefore, there is still room for improvement in the design and management of electrode cables in the existing technology to improve the stability and accuracy of electrocardiogram examination.

[0031] Further, the ends close to each other of the two side plates 56 and the left end and the right end of the middle plate 52 are respectively linearly arrayed with five wire laying grooves 591, the inner arc surfaces of the ten wire laying grooves 591 are linearly arrayed with a plurality of ball bearings 592, the side edges close to each other of the two side plates 56 and the left and right side edges of the lower end of the middle plate 52 are linearly arrayed with five semicircular blocks 593, and the upper side edges of the ten wire laying grooves 591 are fixedly connected with arc-shaped plates 594.

[0032] Further, the surfaces of the five semicircular blocks 593 on the same side are arc surfaces, and the five arc-shaped plates 594 on the same side are semicone-shaped.

[0033] In use, first, the input end of the electrode cable to be used is inserted into the interface of the electrocardiograph 4, then the electrode cable is sequentially placed between the two wire laying grooves 591 close to each other on one side of the patient's body, when the placement is completed, the corresponding names can be marked on the ten writing plates 53, then after the electrode is attached to the patient's body, the knob 588 can be rotated to drive the gear 581 fixedly connected therewith to rotate, when the gear 581 rotates, because the upper and lower racks 583 are meshed with each other, and the surfaces of the two limiting plates two 582 are slidingly connected, and the rear ends of the limiting plates two 582 on the same side are fixedly connected with the front ends of the side plates 56 on the same side, therefore when the gear 581 rotates, the two racks 583 can drive the two side plates 56 to simultaneously move inward, when the two side plates 56 move inward, the push plates 586 fixedly connected with the front ends thereof also move; Further make two push plate 586 slide into the limiting hole 585, at the same time, by setting groove 587 on the end of two push plate 586 close to each other, make two push plate 586 slide into the limiting hole 585, the cavity formed by two grooves 587 will not affect the rotation of knob 588 after that; When the two side plates 56 are brought close to each other by rotating the gear 581, the two side plates 56 can drive the limiting plate 55 fixedly connected thereto to slide into the rectangular hole 54 on the same side, and when the two side plates 56 and the left and right ends of the middle plate 52 are in close contact, the gears 581 on the left and right sides are in close contact, thereby limiting the electrode cable placed in the inner cavity thereof; When the cable needs to be combed, only the two sides of the two side plates 56 need to be held, and then the whole line combing assembly 5 is lifted up by holding the grooves 57 on both sides with both hands, so that the several balls 592 rotatingly connected to the inner surface of the wire slot 591 roll on the surface of the electrode cable, thereby straightening the electrode cable; In the process of using the electrode cable, in order to avoid the electrode cable being placed at right angles when being pulled, the arc-shaped plate 594 is fixedly connected to the upper edge of each wire slot 591, so that when the arc-shaped plates 594 on the left and right sides are close to each other, as known from the above, the five arc-shaped plates 594 on the same side are all arranged in a half conical shape, so that the two arc-shaped plates 594 together form a complete inverted circular cone, and the edge of the upper side of the circular cone is rounded, so that when the electrode cable is pulled, the bending part will be in a circular arc shape after contacting the surface of the arc-shaped plate 594, thereby avoiding the electrode cable being bent at right angles for a long time, which causes cracks on the surface of the electrode cable; After the ECG examination of the patient is completed, the data is transmitted to the electrocardiograph 4 through the electrode cable. When the medical staff needs to store the electrode cable after recording the data, they only need to remove the electrode pads from the patient, hold the two side plates 56 downward, buckle the holding grooves 57 on both sides, and press the wire straightening assembly 5 downward. When the rectangular plate 51 moves downward, it can simultaneously squeeze the sliding plate 17 on the same side. As known from the above, the upper end of the rectangular plate 51 is provided with a circular hole matched with the two guide rods 16. Therefore, the rectangular plate 51 moves downward under the guidance of the guide rods 16 and the sliding plate 17, and the sliding plate 17 squeezes the spring 18 on the same side. After the two side plates 56 and the middle plate 52 are attached to the left and right ends, as known from the above, the surfaces of the five semicircular blocks 593 on the same side are arc-shaped. Therefore, the two semicircular blocks 593 on the same side can be attached to each other to form a complete arc shape. When the wire straightening assembly 5 is pressed downward, the arc surface formed by the two semicircular blocks 593 on the same side can straighten the electrode cable wound in a spiral shape on the same side. After the electrode cable is straightened, the pressure on the wire straightening assembly 5 is released. At this time, the spring 18 is no longer squeezed by the downward pressure, so that the sliding plate 17 drives the rectangular plate 51 to return to the initial position. Then, the knob 588 is rotated in the opposite direction, so that the knob 588 drives the gear 581 to rotate in the opposite direction, thereby driving the two side plates 56 to move outward. The process of moving the two side plates 56 outward is opposite to the process of moving inward. Therefore, this scheme will not be described in detail again. After the two side plates 56 move outward to the initial position, the electrode cable is pulled out of the output end of the electrocardiograph 4, and then the electrode cable is wound on the winding column 11 in sequence for subsequent use. Then, the wire straightening assembly 5 is lifted upward by holding the side plates 56 on both sides, so that the rectangular plate 51 is separated from the surfaces of the two guide rods 16. Then, the L-shaped baffle 35 is pulled apart, the semicircular blocks 593 on the same side are aligned with the placement grooves 33 on the same side, and the wire straightening assembly 5 is placed into the inner cavity of the cavity box 31. Then, the L-shaped baffle 35 is pushed forward to close the inner cavity of the cavity box 31, so that the atomizing disinfection mechanism 32 sprays atomized disinfectant gas to disinfect the wire straightening assembly 5. When the electrode cable wound on the surface of the winding column 11 needs to be used again, the scraper 12 can be lifted by holding the handles 14 on both sides. When the scraper 12 is lifted, the electrode cable wound on the surface of the winding column 11 can be scraped out because the sliding holes 13 on the upper end of the scraper 12 are matched with the winding columns 11. Then, the electrode cable on the upper end of the scraper 12 can be taken and used.

[0034] The atomizing disinfection mechanism 32 described above is a conventional setting in the prior art. Its specific structure and operating principle are as follows: The atomization disinfection machine first sends the disinfectant to the atomizer through the electric pump, and the atomizer uses the principle of ultrasonic wave, air pressure or high-frequency vibration to break the disinfectant into extremely fine droplets. These droplets can float in the air and penetrate into small gaps, instrument surfaces and other locations. Generally, the diameter of the mist droplets is between a few microns and tens of microns, which can effectively cover the surface of the object and quickly distribute the disinfectant evenly. The disinfectant contacts bacteria, viruses and other pathogenic microorganisms through these fine droplets in a short time, thereby achieving sterilization or disinfection.

[0035] For the disinfection of medical instruments, the use of the atomization disinfection machine has the advantage that it can comprehensively disinfect instruments with complex shapes and small gaps, which may be difficult for traditional disinfection methods to effectively cover due to irregular surfaces or inaccessible parts. Atomization disinfection can ensure that the disinfectant penetrates into these difficult-to-clean areas, thereby achieving complete disinfection. The mist droplets can not only disinfect the external surface of the instrument, but also enter the internal cavity of the instrument, such as catheters, needles, etc., effectively eliminating potential pathogenic microorganisms. The atomization disinfection machine uniformly distributes the disinfectant on the surface of the object through atomization technology, and with the high permeability of fine mist droplets, it can achieve comprehensive and efficient disinfection. Especially in the disinfection of medical instruments, the atomization disinfection machine can effectively overcome the dead angles that cannot be reached by traditional methods, and improve the comprehensiveness and thoroughness of disinfection.

[0036] Therefore, the atomization disinfection mechanism 32 in the above is a conventional design in the prior art, and its specific shape, mounting method, circuit connection method and control method are all conventional designs, so this scheme will not be described in detail.

[0037] It should be particularly noted that the specific mounting method, circuit connection method and control method of the electrocardiograph 4 used in the present application are all conventional designs, and the present application will not be described in detail.

[0038] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
