ABSTRACT
The purpose of this paper is to overcome the patient’s death and to provide necessary first aid in ambulance until the patient is brought to the hospital. As Ambulance is the first to handle emergency situations and they do not have the required theoretical knowledge and experience. Also Financial and practical reasons do not allow the participation of specialized physicians on ambulance vehicles. So we have implemented a portable medical device that allows telediagnosis, long distance support and teleconsultation of mobile health care providers by specialized physicians and provide them early and specialized pre hospital management during emergency case survival.This device allows the transmission of vital biosignals and still images of the patient from the incident place to the hospital. The transmission is performed through the GSM mobile
INTRODUCTION
Especially in cases of serious injuries of the head, the spinal cord ,internal organs and also in the case of cardiac disease the way of transporting and generally the way of providing care is crucial for the future of the patient.Among them cardiac disease is common killer. Much can be done today to resuscitate a victim of sudden cardiac death (SCD). Time is the enemy in the acute treatment of a heart attack or SCD. a rapid response time in the pre-hospital setting resulting in treatment of acule cardiac events increases mortality and improves patient outcomes dramatically [3-8].12-lead ECGs performed in the ambulance increase time to treatment of thrombolytic therapy effectively stopping a heart attack in progress and preserving heart muscle function [9]. This means that the patient is more likely to return to a normal lifestyle after a cardiac event.
METHOD
We have developed a portable medical device, which allows telediagnosis, long distance support, and teleconsultation of mobile health care providers by specialized physicians, located at a hospital or a specialized health center. This complete system (figure 1) consists of two sites: the ambulance site (mobile station) and consultation site (hospital station). To ensure maximum portability, communications are performed via cellular (mobile) networks and particularly using the GSM standard which has a pan European coverage
MOBILE STATION
The mobile station mainly consists of two components, a Johnson & Johnson - Dinamap plus III biosignal monitor used for biosignals acquisition and a portable PC; the two components communicate using the RS232 interface. The portable PC used is a powerful (Pentium class) PC containing a frame grabber card, a CCD camera (SONY CCB-GC5/P) to capture still images and a Siemens M1 GSM modem for communication with the server.
The mobile station as shown in Figure 2, captures still images of the patient or gets data from the biosignal monitor. The information is stored on the local hard disk displayed on the screen of the PC and transmitted through the GSM modem to the hospital station.
HOSPITAL STATION
The hospital station mainly consists of a dedicated workstation named as the Telemedicine Consultation Terminal (see fig.1.1) which is used as a processing terminal in the hands of the acting expert doctor, called to monitor an emergency case. On this station, the doctor sees the biosignals and still images received from the portable device, online from the emergency scene. Along with this extremely crucial data he has the ability to retrieve additional information on the patient’s past history given that a HIS / PACS system is available. In this case, the system can be customized to exchange data with them. Otherwise, it handles the patient’s medical record by itself. The data received are displayed on the server screen and stored in the Ambulance.
CONTROL PROGRAM
The control program is used by the doctor at the hospital side so as to observe the signals send by the mobile station. The doctor can also send commands concerning the mode of the transmission (Figure 4.1); still image mode or biosignal mode, GSM network and sends commands concerning the mode of the transmission
DATABASEAND ADMINISTOR
Security and confidentiality of stored information are very critical issues to medical archiving systems. Thisapplication database is fully protected from unauthorized access. This database itself is password protected andfully encrypted
CONCLUSION
We have developed a portable medical device to be used for emergency telemedicine applications. The device uses GSM mobile telephony links and allows the collection and transmission of vital biosignals, still images of the patient and bi-directional telepointing capability. This advance man-machine interface enhances the system functionality by allowing the paramedics to operate in hands-free mode while receiving data and communicating with specialists in a hospital, where all relevant data are stored in the ambulance database system. This system is implemented as a part of the ambulance project
