A DUAL MODE ECHOCARDIOGRAM
FIELD OF INVENTION:
The present invention relates to the field of medical technology and more particularly relates to the Electro Cardiogram monitoring.
BACKGROUND OF THE INVENTION:
An Electro Cardiogram Machine is used for recording the Electro Cardiogram signals of a patient during resting phase using a resting Electro Cardiogram and during activity phase using a stress Electro Cardiogram machine. These tests are conducted with specific time duration only. However, during emergencies when patients are admitted, they are monitored using an Electro Cardiogram Monitor which continuously monitors the Electro Cardiogram signals of the patient with alarms being provided to have timely medical intervention when the patient's physiological signs breach the limits set by the attending physicians.
In emergency cases the usual practice is to take a 12 lead Electro Cardiogram first for diagnosing the problem and then the patient is connected to cardiac monitor. And also it is necessary to take periodic resting Electro Cardiograms of the patients in addition to doing the monitoring of his Electro Cardiogram signals. Normally, 2 different equipment are used for this purpose - one for the resting Electro Cardiogram (a complete 12 lead Electro Cardiogram taken on a patient during resting phase for a specific time duration) and the other for Electro Cardiogram Monitoring (The Electro Cardiogram is displayed and read on a continuous basis and will capture the signals as the patient is connected to the machine). An integrated Resting Electro Cardiogram-cum-Electro
Cardiogram Monitor would be of great importance in "saving the time to treatment during critical moments" as both the applications will be available in the same system.
Inventor searched regarding novelty of invention using various databases including USPTO and found a document relevant to our invention namely United States Patent 6,440,067. On perusal of this specification it is found that our invention is different from the cited document.
SUMMARY OF THE INVENTION:
The present invention provides a unique 2-in-1 Resting Electro Cardiogram Machine and an Electro Cardiogram Monitor in the same medical device that allows switching between a Resting Electro Cardiogram machine and an Electro Cardiogram monitor by a software switch. The medical devices are connected to the computer in which the Resting Electro Cardiogram, Electro Cardiogram Monitor software operate in Windows environment.
Cardiac monitors produced in India do not have the in built case sheet that can be transmitted to a remote location for specialist review & opinion. The monitors do not have the capability of transmitting to a remote location using low bandwidth technology like plain telephone line.
But, it would also be highly desirable to have the electronic case sheet of the patient integrated with the Electro Cardiogram signals for display on the monitor for review by the attending doctor. There will be enormous value, addition to the system if the Electro Cardiogram signals as well as the Electronic case sheet of the patient along with resting Electro Cardiogram could
be transmitted on-line in real-time using available low bandwidth telephone technology to a specialist doctor for further reference. This would give the advantage of remote monitoring of the patient condition for enabling appropriate treatment under the guidance of the specialist doctor anywhere anytime, especially whenever such specialist facility is not available locally. This gives the much-needed real-time telemedicine application for a country like India where majority of the population lives in the rural areas.
Dual use Electro Cardiogram with its transmitting capability is a type of realtime telemedicine application providing enormous benefits to society by bridging the gap between the availability of the medical service by competent medical personnel as well as the acute need for the medical service in rural and remote areas.
Appropriate treatment for emergency case, patients will be available anywhere, anytime & can be affordable with the above invention.
