M262157

[Technical field to which the new type belongs] This creation is about "improving the structure of chest-type ECG sensors", especially ^ type of ECG sensors installed on the chest, which can be used to transmit the measured ECG number from the body to the wireless value Connect directly to the receiver by cable or cable. [Prior art] According to the organs composed of muscles by ‘~ viscera’, the muscles that make up the heart are different from ordinary muscles and are called myocardium. When the myocardium is active, it is the heart. An electric current is generated when I record the change of the current as a picture, and then an electrocardiogram can be diagnosed. Through the electrocardiogram examination, we can diagnose arrhythmia and changes in heart shape caused by various diseases. From the changes in the electrocardiogram, we can clearly know Whether the heart beats regularly and is used to investigate the origin of various heart diseases, such as: if the conduction system is defective, it is easy to cause arrhythmia, and the changes on different electrocardiograms can provide medical and related information to understand the heart system Which part of the node may have a problem. In addition to this, when the shape of the heart changes due to various reasons, the electrocardiogram is also simplified. For example, the myocardium increases due to long-term high gray pressure or heart valve disease. When the workload of the heart is increased, the myocardium is enlarged to cope with the increased work. At this time, the cardiac current also changes and the shape of the electrocardiogram also changes. Therefore, from the changes in the electrocardiogram, we can know whether the myocardium is hypertrophic or not. Diseases that increase myocardial workload; in acute myocardial infarction When, due to the damage of myocardial infarction part, it will also appear on the ECG apparent specific changes out, so the ECG for the diagnosis of myocardial infarction is very important, even if not to the heart attack away

M262157 IV. Creation description (2) degrees, but special changes in the electrocardiogram also occur when the stenosis or coronary insufficiency is caused by the contraction of the coronary arteries. Therefore, the ECG Town provides many information for medical personnel. Patients with related diseases are quite important. β Therefore, the author provides a device that can be directly worn on the chest of the body. This device can be wirelessly transmitted by the signal of the electrocardiogram read on the body or directly connected with a signal cable. This signal is sent to the receiver. The user's ECG is monitored at any time, and it is very convenient to use, eliminating the trouble of measuring the ECG only after arriving at the hospital. [Content] The author of this case has learned the lack of the above-mentioned conventional structure, and carefully studied it, and accumulated many years of personal experience in this business, and finally designed a kind of chest ECG sensor structure improvement. " a The main purpose of this creation is to provide a chest-type ECG sensor structure that can be carried around and obtains 2 ECG data immediately, which is quite convenient to use and assemble. In order to achieve the above purpose, this creation "The structure of the chest ECG sensor is changed. It consists of a housing, a circuit board, two fixing straps, and two pieces each on the fixing strap. It is composed of a rubber conductive sheet, which is composed of a top case, and has other baskets on the left and right ends of the bottom case. More than one piece of metal plate or M ^ .1 electrical effect is independently separated from each other. The circuit The board contains a measuring circuit and a terminal: i: The circuit board is installed in the housing, and the electrically conductive rubber or metal spring of the circuit board respectively contacts the above-mentioned corresponding ones.

Page 6 M262157 4. Creation instructions (3) Metal plates or other materials with conductive effect, and the bottom surface of the fixing band is provided with two or more pieces of rubber-like conductive strips that are separated from each other and do not communicate with each other. And the fixing bands are respectively installed at the two ends of the casing, so that the outermost measured ends of the long sheet-shaped rubber conductive sheet are pressed against the metal plates on the left and right ends of the bottom case or other substances having a conductive effect The electrodes of the measuring circuit are connected to the corresponding rubber conductive sheets to prevent them from conducting each other. After the assembly according to the above structure, the ECG sensor is directly placed at the appropriate position on the chest of the user. After the two sets of rubber conductive pads on the fixed end of the end are respectively connected to the electrodes of the measurement circuit, the rubber conductive pads will directly contact the skin to obtain the value of the change in the heart current. 'This value is sent to the measurement circuit on the circuit board. To perform calculations and convert them into digital signals of the electrocardiogram. This digital signal can be transmitted through the transmitting circuit inside the casing or directly connected with a signal line. Value is transferred to the receiver to display the ECG, and the receiver can be equipped with hand or hung in at the waist, can not only portable and very convenient to use. [Implementation] The structure, device, and features of this creation are described as a preferred feasible embodiment and illustrated in detail as follows: Please match with the first, second, and third illustrations. "Structural improvement" is composed of a casing 10, a circuit board 20, two fixing bands 30, and two left and right ends of the fixing band, which are independently separated and do not communicate with each other, and the shell 10 'It is composed of the bottom shell 12 and the top shell 11, and is to the left of the bottom shell 12,
