INTRODUCTION :INTRODUCTION The concept of telemedicine is to compensate the spatial distance between patient and physician using telecommunication devices GSM modem transfer the measurements of capillary BG concentration, to health care provider Leads to better glycemic control and hospitalization cost in diabetes therapy


Slide 3:Telemedicine also integrated in diabetes education. Another way of telemanagement is the remote control of drug delivery such as an insulin pump using telecommunication system. Effective monitoring phase and accurate realization of therapy.


MATERIALS AND METHODS :MATERIALS AND METHODS Insulin pump via the global system for mobile communication Control commands are transferred in encrypted form via (smsc) GSM modem equipped for connecting sms

Control of insulin release :Control of insulin release Infrared detector signal binary counter Eight impulses of IR detector relates 44 motor steps and release 1I.U of insulin from the reservoir Every 8th signal from binary counter of I.R detector transferred to the GSM modem SMS connect the computer for programming the insulin release

CONCLUSION :CONCLUSION In the future the drug delivery using telemetric techniques will become more and more important In the present investigations an experimental insulin has been developed which is remote controlled via computer program and GSM The pump can be programmed in advance for a time period of 24h


PERSPECTIVE :PERSPECTIVE Telemedicine program effective in diabetes monitoring & reducing diabetes related crisis. Intervention program design more essential than technology in program success. Change theories may enhance program success.


Slide 17:Telemedicine has the potential for larger scale community based tele-diabetes intervention. Collaboration may involve organizations with interoperable personal health record systems. Large scale intervention has the potential of efficiency of scale
