1.1 Introduction
Telemonitoring is a medical practice that involves remotely monitoring patients who are not at the same location as the health care provider. In general, a patient will have a number of monitoring devices at home and the result of these devices will be transmitted via a telephone to the health care provider.
A Telemonitoring system incorporates innovation technology with in-home, self-monitoring assistances to collect real time updates regarding your loved ones vital signs. The self-monitoring test result are captured and transmitted to a central database that stores the information that can be accessed remotely by the patient, family and their healthcare team. Actions and modifications can be made with the results and can be utilized for on-going care recommendations.
General Packet Radio Service (GPRS) is a data transfer specification used by the Time Division Multiple Access (TDMA) and Global System for Mobile communications (GSM) networks. The GPRS system makes use of the entire coverage area and frequency of its host networks to transmit data packets. Data packets are segments of data sent between computers or network devices. The GPRS system provide subscribers uninterrupted data connection instead of a dial-up connection.
Global Positioning System (GPS) is a navigation system for portable devices. It uses a network of satellites surrounding the planet. A compactible device such bas a smartphone or a dedicated navigation device has a built-in receiver chip that picks up regular signals from the satellites. Each signal is time-coded so the device can calculate how far away it is from the satellite based on the time the signal takes to arrive. By combining the distances from at least four satellites, the device can calculate its position to within a few feet. It can also cross-reference this with map data to provide navigation such as driving directions.
Emergency patient Transportation is handled with an ambulance which is a vehicle for transportation of sick or injured people to, from or between places of treatment for an illness or injury especially in emergency and I some instance will provide out-of-hospital medical care to the patient.
1.2 Background of Study
Mater Misericordiae hospital, Afikpo is a voluntary agency built and opened by catholic bishop of Abakaliki diocese, Late Bishop Thomas Macgettrick in1946 with 24beds which has evolved over the years to 300beds. It is now managed by the Catholic Diocese of Abakaliki under the proprietor, His |Lordship most rev. Dr. Michael Nnachi Okoro, heading the hospital board which supervises and coordinates the activities of the hospital.
The hospital stands on 18.5 acres of undulating land leased to her since 1946 by the people of Evuma and Ugwuegu in Afikpo North Local Government Area Ebonyi State. It is situated away from the centre of Afikpo town, but with easy accessible road network.
The hospital has a large theatre and most of the latest medical equipments needed to serve you better. Most of these equipments are rarely seen in private hospitals around and even the public ones. It also has ambulances and other buses to facilitate the work in the hospital.
1.3 Statement of the Problem
The number of road accidents victims in every busy city like Afikpo(with the presence of a higher institution) can be unimaginable. Immediate medical attention to critically ill patients and accident victims followed by transportation to a well equipped local facility within the golden hour can save many lives.
Ambulances are specifically designed to carry emergency drugs and instruments. The inner area of an ambulance is fabricated in such a way that it houses emergency medicine, sterilizer, stretcher and so forth. The personnel inside the ambulances are specially trained to be emergency technicians. There exist a need to augment the skill of such paramedics with the Central Monitoring Station(CNS). The CNS helps in identifying the nearest and appropriate hospital and coordinating with the medical personnel of the hospital.
1.4 Objective of the Study
The purpose of this project work is to design and implement a system that cater the specific requirement of acquiring physiological data, keyed-in data, patient snapshot, and voice signals and transmitting them using a cellular network to a Central Monitoring Station that helps in identifying the nearest and appropriate hospital and coordinating with the medical personnel of that hospital. Placing the system in an equipped ambulance that can take vital signs, assess oxygen saturation, monitor blood pressure etc. that will reduce the risk of death involved in Emergency Patient transportation.
The aim of this work is to design a data transfer and navigation system into a telemonitoring system for the purpose of facilitating information passage between the operators of the telemonitoring system and ambulance drivers in Mater Misericordiae Hospital for the emergency transportation of patients.
