Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrocardiogram (ECG) recorder technology, and in particular to a dynamic ECG recorder. Background Technology
[0002] Cardiovascular disease (also known as heart disease) is a class of diseases involving the heart, blood vessels (arteries, capillaries, and veins), or both. Cardiovascular disease can refer to any disease affecting the cardiovascular system, primarily heart disease, cerebrovascular disease, kidney disease, and peripheral artery disease. Cardiovascular disease is one of the leading causes of death, and many heart disease patients are highly susceptible to death due to the failure to detect lesions in time and provide early intervention. Electrocardiogram (ECG) is the most direct means of detecting heart disease. An ECG is a technique that uses an ECG machine to record the changes in electrical activity of the heart during each cardiac cycle from the body surface. ECG can diagnose rhythm abnormalities caused by damage to the heart's electrical conduction tissues and changes in heart rhythm due to electrolyte imbalances. A dynamic ECG recorder, as a type of ECG recorder, can operate under dynamic conditions, bringing significant convenience to medical treatment. Dynamic ECG recorders have an internal Bluetooth module, and external visual devices connect to the Bluetooth module of the dynamic ECG recorder via Bluetooth to acquire the dynamic data of the subject in real time.
[0003] In existing dynamic electrocardiogram (ECG) recorders, to ensure the electrodes fit snugly against the body at the measurement site, the electrodes are positioned on the side of the circuit board away from the main unit and power supply. The circuitry on the circuit board connects the electrodes, the main unit, and the power supply. Therefore, printed circuitry is required on both sides of the circuit board. Since the ECG recorder needs to connect multiple electrodes, the circuit board requires multiple branches connected to the bottom circuitry. The circuitry on the side surface connects the circuitry on the top and bottom surfaces of the circuit board. This circuitry structure is not only difficult to print, but also, due to the thinness of the side surface of the circuit board, the high pressure during impact can break the circuitry on the side surface, requiring protective wrapping.

[0040] After the lower release film 1 is used to protect the medical cloth tape 3 and the conductive gel sheet 2, after the lower release film 1 is torn off, the second medical double-sided adhesive 12, the medical cloth tape 3 and the conductive gel sheet 2 can be directly pasted and fixed on the skin. Tearing off the release film 9 can make the second medical double-sided adhesive 12 more flexible and able to fully adhere to the uneven skin.
[0041] In a preferred embodiment of this utility model, the outer casing consists of a battery base 5 and a battery retaining cover 8 that is screwed onto the battery base 5; the outer side wall of the battery base 5 has multiple slots 502 evenly distributed around its circumference; the inner side wall of the battery retaining cover 8 has multiple retaining strips 801; the battery retaining cover 8 is fixed to the battery base 5 after being screwed onto the slots 502 by the retaining strips 801; the battery retaining cover 8 and the battery base 5 are fixed together by a screw, which facilitates the replacement of the button battery 11.
