This project proposes to build a multifunctional Telemedicine facility, which would see to the monitoring of the patient through a virtual instrument that was fed with physiological signals via appropriate hardware circuitry and henceforth connected to a Personal Computer (PC) loaded with the appropriate application. This yielded to the outcome that a bedside nurse was the only main criteria required in the monitoring of the patient’s parameters at the health care setting extremity. In case of abnormalities or critical conditions detected, the parameter waveforms could be transmitted to the physician’s Messenger service for his/her examination.
The “Web-based Multifunctional Virtual Instrumentation for Telemedicine” comprises of both a hardware implementation as well as the software implementation. The hardware implementation involves the process of obtaining the Electrocardiograph signals, the heart sounds, temperature, and pressure pattern and respiration signals of the patient in the Intensive Care Unit. Once the appropriate signals are obtained onto the kit, the signal is converted into digital signals by the Analog to Digital Converter. The output from the hardware is connected to the PC through the parallel port interface.
The software implementation, on the other hand, deals with the conversion of the digital signals obtained into their appropriate waveform and promoting them onto the application; it involves the calculation of the ECG, pressure, and temperature and respiration rate. The rate is calculated by using the digital signals fed through the parallel port. The major feature has it sending the signals over the Internet to a physician or specialist at a remote site for expert opinion. As a last step, the project also includes the feature of the physician being able to send back suggestions or recommendations for future monitoring to the bedside nurse via the Messenger service itself. In all the consultation scenario has been depicted by Fig. 1.The hardware kit is connected to the appropriate probes for the receiving of the various parameters from the patient. It is also connected to the PC through a parallel port interface. Using the parallel port gives the added advantage that a total of 0 to 255 data values can be sent. The system flowchart depicting connection between remote physicians and the patient monitoring system is shown in Fig. 2. The PC loaded with the virtual instrument is connected to the network and Internet at the Sender side as and when required. At the receiver’s or doctor’s end, only the application and a connection to the Internet are sufficient.
