1. Field of the Invention
The present invention is relates to an apparatus of an improvement on chest cardiogram sensor, especially refer to a device of cardiogram sensor fasten on chest and transmit measured digital signal of heartbeat by wireless or cable to receiver.
2. Background of the Invention
Human heart is organized from muscles which is different from usual muscles and called cardiac muscle. When cardiac muscles are in active, that means heart beat and generate electric current, cardiogram sensor detects and records electricity activity in the cardiac muscles of heart and translate into curve diagram. By the diagnosis of checking the curve reflects from the cardiogram sensor, heart disease and pathogenic like arrthymia, etc. can be found out immediately. That is, from the diagnosis of checking cardiogram curve, we can judge if the heart is regular or not. Arrthymia always caused by the problem of heart conductive system, a doctor can judge from the curve shown by the cardiogram sensor to analysis and find out which part of the heart organ may have problem; In addition, the heart status may be altered by various kinds of heart diseases and shown different cardiograms on the sensor. The burden of heart workload increased by the reason of long-term high blood pressure or valvular disease will cause thicker cardiac muscles to care about the premium workload, whereas under such condition the heart electricity activity changes and also changes the curve of the heart cardiogram, therefore checking the curve of the heart cardiogram can diagnose if the cardiac muscle is thicker or not, and by the way indirectly detects some other heart diseases which increase workload of cardiac muscles. When in acute cardiac muscle infarction, cardiogram sensor will also show special apparent curves, hence heart examination with cardiogram sensor is an important therapy to the patient of cardiac muscle infarction, even in the pre-stage of cardiac muscle infarction, the chest pang or coronary hypogenesis caused by coronary shrink will also detects by cardiogram sensor. In general, cardiogram sensor provides doctor many valuable information concerning related patients.
Accordingly, the present invention provides a portable apparatus which could fasten on chest to read the body digital signal of cardiogram, and send by wireless or cable cord to its receiver. It is not only monitor the user's cardiogram from time to time, but also ready and convenient to be used outside of hospital.
It is therefore a primary object of the present invention to provide an apparatus of improvement on the structure of chest cardiogram sensor.
It is the further object of the present invention to provide a portable and instantly measurement of cardiogram data of chest type cardiogram sensor mechanism, for convenient use and assembly.
The apparatus in accordance with the present invention primarily comprises a shell, electric board, two fixed belt, and two indecent mutual unconductivity rubber plate, and the shell is combined from bottom shell and top shell, and at the right and left edge of the bottom fixed two or multiple independent unconductivity metal plate or some other related conductive materials. Whereas, the electric board included measurement circuits and emitter circuits assemble into the shell, at both edges of circuit board contact respectively with above mentioned metal plate or some other related materials by conductive rubber or metal plate. At the bottom of fixed belt set up two or multiple independent mutually unconductive long rubber conductive plates, while the fixed belt fitted at both edges of the shell to make the outer edge of the long metal plate press under both edge of bottom shell, and electrode of measurement circuit board connect with opposite conductive rubber plates to avoid mutual conductive.
According to the description mentioned above, directly fasten the cardiogram sensor on the appropriate position of user's chest. Owing to the two sets of conductive rubber plate under the right and left ends of fixed belt connected with the electrode of measurement circuits respectively, and the conductive rubber plate further contacts with skin to get the signal data of heart electric activity, and send to measurement circuit board for calculation and translate the signal data into the digital signal, then transmit the digital signal to receiver so as to show the cardiogram. The receiver could fasten on the wrist or waist, not only portable, but also convenient.
Embodiments of the present invention will be described herein below by reference to the accompanying drawings and an adequate practical example:
First of all, referring to
Whereas, circuit board 20 includes measurement circuits 21 and emitter circuits 22, among which the two electrodes 21a at both ends of measurement circuits 21 designed to connect with conductive rubber plate or metal piece 21b, when assemble circuit board 20 into shell 10, each conductive rubber plate or metal piece 21b of electrode 21a contact with metal plate 11a; and then the emitter circuits 22 function as sending measuring data to the receiver 23 which can be fasten on wrist or waist.
Furthermore, fixed belts 30 arrange at both ends of the shell 10 and press the outer end of conductive rubber plate 40 onto the metal plate 11a at the shell 11 bottom so that conductive rubber plate can contact with circuit board 20 to form a loop circuit.
Please also refer to
In summary, the present invention “an apparatus of improvement on the structure of chest cardiogram sensor” fixed measurement circuits in the electric board to measure and get the calculated cardiogram data, and send to receiver which is portable for carry, assemble easily, convenient to use and receive cardiogram data immediately. Many changes and modification in the above-mentioned embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and intended to be limited only by scope of the appended claim.
