PREAMBLE TO THE DESCRIPTION
The following specification describes the invention.



Field of the invention
The present invention relates to a method and device for Real time communication of human physiological data. More particularly it relates to a method and device capable of capturing the physiological data of a patient at any location and transmitting such data through internet to the place of analysis, e.g. Hospitals and the like.
Background of the invention
In recent times, the word "telemedicine" has acquired much importance. It actually means distant medicine. The object of "telemedicine" is to integrate the electronic communication systems to transmit patient data to the place of analysis even from remote locations. This is a step forward to enable the patient to send his correct physical condition details in the appropriate medical terms using sophisticated technologies in a very cost effective manner.
Currently the equipments used in hospitals provide the record of the patient's data by way of hard copy or paper prints. These contents are either sent by to the doctor by fax or alternatively the record is read out orally over phone by the medical attendant. The devices or equipments also send such data to a Central monitoring station, which is available only in Intensive Care Unit, through wired connections. But these systems suffer from Inherent (jrawba^s. They are highly prone to. hqrnan error. There pan be gross mistakes in reading out the data over phone.
In India, the mobility of such equipments is a big operational issue as such equipments are bulky and less mobile. Thick mesh of wires complicates things even further. Hence if the doctor is not available at the location of the patient, the patient's physical condition


details cannot be made available in real time and thus causes a lag in medical attention. This may prove very costly as it may be detrimental to the patient's health.
Therefore there is an urgent need to provide sophisticated electronic communications systems that are able to communicate the physiological data of a patient from any location to the point of analysis in real time. Such physiological data may be Electro Cardiogram [ECG] data and like patient data.
It is at least one object of the present invention to provide a method and device to achieve an efficient and effective telemedicine system.
It is also an object of the invention to transmit patient data in real time from one location to another.
It is also an object of the present invention to optimize large data and signal streams in order to use less communication bandwidth resulting in cost savings.
tt is yet another object of the present invention to provide a sophisticated technology driven solution to remotely access virtual-real time waveform and other critical data of a patient, directly from a device attached to the patient.
It is also an object of the present invention to provide ambulatory devices and connect them to health-care facilities using low cost telemedicine infrastructure and to enable deployment of such technology as an extension of the currently existing medical facilities available at such health-care facilities.

Brief description of the invention
The present invention relates to a method and device capable of capturing the physiological data of a patient at any location and transmitting such data through internet to the place of analysis. Such data may be ECG or the like. The device transmits the captured data wirelessly through the internet to a remote server that may be hosted within the premises of the point/location of analysis such as hospital or the like. Alternatively the server can be hosted at any other location. The device can also post the data directly to the Hospital Information Systems or to web-base electronic medical record systems.
Once the data reaches the server, it is converted into an image and transmitted for analysis to the location of the doctor, which can be the hospital or directly to a hand held device, such as but not limiting to a mobile device - a mobile phone. It can also be transmitted to a desktop PC. The hand held device is pre-equipped with the defined architecture and utilizes a wireless connection to securely receive the patient's data from the hospital network or the like. The data can also be transmitted in raw form to show live plotting of the waveform on the hand held device such as a mobile phone.
The device can be wirelessly connected to the internet either by Wi-Fi, bluetooth or GPRS modem. It can be battery operated thereby eliminating the need of electric supply. Additionally, the present invention provides for a protocol to transmit the patient's captured physiological data to a remote server, create an electronic record and store it in a data repository.

Advantages:
96
1. Real time acquisition or capturing of patient's physiological data such as ECG or the like, processing and transmittal to the location of analysis such as Hospital or the like. For example in case of an ECG, doctors are able to remotely view the ECG within 40 -60 seconds of its creation.
2. Multi-mode adaptable communication with handover - modules that can "communicate and switch" intelligently without user intervention, to ensure seamless mobility. Two communication media like GSM and Wi-fi can be connected at the same time and the system can sense and choose a working medium if either fails. This ensures connectivity at all times.
3. Optimization of battery usage to specific needs of medical devices resulting in better battery management.
4. Control of noise pollution to avoid possible interference with other sensitive medical equipment already in use.
5. The data capturing device is highly convenient due to its smaller shape.
6. The captured data records can be viewed on standard mobile phones giving tremendous flexibility to Doctors
7. Records can be accessed on mobile phones even outside the hospital premises.
8. In case of unavailability of network, device can be equipped with storage capacity of several months of records.
9. It can be used even in ambulances due to its size and telecom connectivity enabling emergency medical care services.
10. The present invention has special technobgical enablement provisions to ensure patient privacy with secured encryption techniques.

The present invention can also be extended to capture other data such as glucose monitors, blood pressure, fetal monitors and the like.
