Description

Technical Field

[0001] The present application relates to the field of medical auxiliary equipment, and in particular to an electrocardiogram chest lead fixing device. Background Art

[0002] Conventional electrocardiogram is a graph of various potential changes drawn from the body surface by an electrocardiograph. It is an objective indicator of the occurrence, propagation and recovery process of cardiac excitement. It can accurately and timely understand whether the patient has arrhythmia, and has positive value in the diagnosis and analysis of various arrhythmias and conduction blocks. It can also reflect myocardial ischemia events in a timely manner. The characteristic electrocardiogram changes and evolution are a reliable and practical method for diagnosing myocardial infarction. As an important auxiliary examination item, it is now widely used in clinical diagnosis and treatment.

[0003] Electrocardiogram electrodes are placed on different parts of the human body and connected to the positive and negative electrodes of the electrocardiograph through lead wires. This circuit connection method for recording electrocardiograms is called electrocardiogram leads. The internationally accepted lead system currently used in electrocardiogram examinations is called the conventional 12-lead system. For patients with chest pain, the 18-lead system is mostly used, which includes the above-mentioned 12-lead system and 3 right chest leads and 3 posterior wall leads.

[0004] The chest lead electrodes used in the electrocardiogram examination are attached to the corresponding parts of the chest by independent lead balls for examination. It is composed of a metal suction ball base and a silicone suction ball on it. There is a semicircle on the base to connect the wire pins. The wire is directly connected to the electrocardiograph for sampling. The lead ball is attached to the chest and needs to be kept fixed during the examination. It cannot shake or fall off to ensure the integrity and accuracy of the sampling. It is of great significance to quickly and easily fix the chest lead electrodes.

[0005] The chest lead electrode that combines a silicone suction ball with a metal base has a large and small suction base. The large suction balls are easy to interfere with each other when encountering patients with thin chests. The small suction ability is relatively weak and easy to fall off. The small ball is chosen between the two, but the small ball is easy to fall off and needs a fixed support. The suction ability of the chest lead electrode combined with a silicone suction ball and a metal base is relatively stable when facing patients with normal sebum, but it is basically not adsorbed when encountering thin patients with too little sebum, or patients with dry and wrinkled skin. It needs to be fixed with external force, otherwise it cannot be examined. For agitated patients or children, if the six leads in front of the chest are not fixed at the same time, it is easy to cause interference due to the swing of the chest, so it is particularly important to quickly provide a relatively firm device as a support in this case.

[0006] Among the many improvement plans, there are mainly two ways. One is to use an elastic band for fixation. However, using only one elastic band does not have enough fixing strength, especially for skinny patients who are not easy to cooperate. The suction ball is not stable enough. Moreover, there is only one elastic band, so the positions of six leads can only be fixed on one plane, which contradicts the fact that in actual operation, the electrodes need to be fixed on three horizontal planes.

[0007] Another method is to use a silicone layer on the elastic strap to fix the lead and then fix it with a cover with Velcro. However, only six fixing slots are reserved. If the chest shapes of different patients are too different, the slot positions are difficult to align. The lead electrode may not be accurately fitted, affecting the examination results. The Velcro cover will increase the friction between the electrode and may create unnecessary interference. Utility Model Content

[0008] In order to make up for the above shortcomings, the present application provides an electrocardiogram chest lead fixing device, which aims to improve the chest morphology of different patients. If the difference is too great, the position of the card slot is difficult to align, and the lead electrode is not accurately fitted, affecting the examination results. The Velcro cover will increase the friction between the electrode and may create unnecessary interference.

[0009] An embodiment of the present application provides an electrocardiogram chest lead fixing device, comprising a first elastic band, a second elastic band, a third elastic band and a silicone card block.

[0015] In a specific embodiment, a plurality of button slots are equidistantly provided at one end of the first elastic band, the second elastic band, and the third elastic band away from the button, and the distance between adjacent button slots is 5 mm.

[0034] The chest lead electrode is initially fixed on the thorax by using a high-elastic elastic band. The advantage of the elastic band is that it can be used for patients with different thoraxes. The fat and thin only need to adjust the position of the following buttons. Here, the elastic band is used to open holes from the end to the front.

For some thin patients, patients with bad skin or poor cooperation, the electrodes are easy to fall off. This fixing device firmly fixes the electrodes in the accurate position on the chest, has strong operability, strong practicality, high accuracy, and the tool can be reused. The electrocardiogram can be quickly performed on patients with thin bodies, wrinkled and dry skin, and agitated emotions.
