Recently, the wireless sensor network, as a data acquisition system, and the information communication technology is widely used to improve the medical environment. Online telemedicine systems are useful due to the possibility of timely and efficient healthcare services. Patient monitoring consumes the medical staff’s time and continuous monitoring was not possible. Furthermore, there is no reference database for previous patient’s data and no integrated linking of the physician, pharmacy, laboratory, and the hospital management. Moreover, the pharmacist cannot refer to a database to avoid treatment conflicts. This research developed new system to provide a capability for important physiological data, lab investigating, doctor’s notes’ diagnoses’ and treatments to improve the quality of healthcare services for patient and doctors. The methodology of this system is divided into two parts, 1) data entry and querying system and 2) wireless monitoring and acquisition system. The first part is a desktop application and database on the server. An employee will enter the information about the patient, doctor, lab doctor, and pharmacist through a desktop application. That information will be stored in the database. All queries about the patient’s statue and physiological signals come from that database. The simulation scenario has two nodes one patient node and hospital node. The patient node contains one of the temperature, blood pressure, heartbeat and pulse oximeter (SPO2) sensors. The sensors are placed on patient's body to collect the real-time physiological data about his health. Sensors connected to microcontroller and data from microcontroller are transmitted to the server through wireless communication. Proteus software was used as a simulation tool, and, visual studio 2010 VB.net and SQL server 2008 was used for the database and interfaces. The important experiential results of the system were the accuracy and a fully interconnected medical environment units with the patient. Furthermore, the system has provided a paperless system and the transmission of that data done with no errors in all conditions. All patient's data are stored on a single server and the doctor can continuously monitor the patient's condition and can access the information whenever needed and not need to be physically present. In conclusion, using this system will help the doctor continuously monitor the physiological signals of patients in real time. This study recommends adding more sensors like EMG and ECG sensor to measure other parameters. Furthermore, GSM can be used to send SMS alarming messages to a medical staff when the monitored data go outside their normal ranges.
