Abstract

According to National Fire Administration statistics, 92 years, the number of the emergency ambulance and escort injury statistics about 41 million. ^{So many}

unexpected emergency patients to an accident, emergency first aid course of time is a very important project, this study integrates the voice and

communication technology, using Microsoft Visual Basic 6.0, Speech SDK 5.1, mobile devices TREO-600, the system modem AOPEN FM56-EXV, development of remote voice emergency triage support system, through escort input data to provide triage triage classification, classification, area of the proposed value, can be classified as an emergency room nursing staff reference. The system total of 26 images, voice, vocabulary 338. The system built in this study averaged 106 seconds to complete a triage operation, at 63 dB noise environment of up to 94%

of the speech recognition rate.

Background

According to National Fire Administration statistics, 92 years, the number of the

emergency ambulance and escort injury statistics about 41 million people, of

which 40% do 36% of the acute disease and accidents [1], how by the appropriate

medical staff, at the right time location, fast, accurate distinction between patients and provide appropriate care to take care to protect patient care and increase well-being of the effectiveness of emergency medical care will become a very important responsibility and the impact that this responsibility first and foremost task is to triage [2], Ru Ci emergency treatment in the previous studies are mostly set in the ambulance or GPRS voice GPS navigation system to enable smooth escort can find the nearest hospital for emergency treatment time for patients admitted to hospital as soon as possible, but in addition to other early hospital , escort patients to the hospital if the further processing before such as triage, and synchronization to the emergency room medical staff the patient's situation can help patients with medical personnel to grasp more information and to give patients with early preparation treatment of environment and equipment, prime time for first aid is bound to have a better grasp.

Research Methods

First, the research environment

Because the hospital's call center inquiry services are mostly used for patients with hard physical Shebeijiage expensive, and not a Yiliaoxiaoyong, this study Caiqu simple economic hardware design, Kaifa issued by the practical value of medical communications call center.

Second, development tools

The system uses a program development tool for the Microsoft of Microsoft Visual Basic 6.0 and RS-232 interface, with its speech recognition development tools, Microsoft Speech SDK 5.1 and Simplified Chinese Language Pack [19], NS Basic PDA development tools. Remote telephone for the TREO-600, as shown in Figure 1, modem to AOPEN FM56-EXV, as shown in Figure 2. The concept design calls for the remote transmission module GPRS module and dual mode.

Third, the system architecture

1. Remote communications module

The system for remote hand-held telephone devices in accordance with the Agreement TAPI telephony signal transmission through the telecommunications company switches to the emergency room modem module device through the circuit chip from the RS-232 interface to connect the host to detect caller ID, automatic answer phone, record voice messages.

2. Voice triage module

Triage was an intelligent agents module, triage patients by monitoring the properties of objects and events, the decision for the proposed classification and disposal, and can perform a number of built-in actions, such as the transmission of information related processes, or notify the relevant emergency doctors. ^Voice

module using the Microsoft Speech SDK 5.1 of SOC, which provides speech

recognition and text to speech function. Lexical database for the XML file, store and vocabulary needed to identify relevant information.

3.GPRS transmission module

Hand-held mobile devices to run triage action, classification and disposal of a resolution, through the built-in GPRS systems will aid the message transmitted to the emergency room patients with the host system.

Outcome

This study developed a remote emergency triage voice system, able to use the

remote communications module, and through voice control, the interface protocol

based on TAPI, with caller ID, message date and time of main functions such as

auto-answer, similar to the in a small call center

Development of interfaces shown in Figure 1, telephone messages entered, the automatic identification of the caller, the caller starts the basic information (see Figure 3).

Entered through voice recognition immediately after the triage system, escort and began to describe the basic information of patients for signs of life (see Figure 4), then after the completion of the triage system identification procedure (see Figure 5), hospital care by triage to immediately single ( reference Figure 11), prepare patients required emergency environment, personnel and equipment to the most rapid process will make the best first aid treatment of patients.

Implementation of hand-held mobile system triage program, enter the identity confirmation (see Figure 6) into the emergency room triage of patients fill out basic information and vital signs (see Figure 7, 8), the completion of data collection and storage (see Figure 9) through the GPRS data transfer mode will be transmitted to the emergency room triage host to receive and print single (see Figure 10, 11), medical personnel can get to understand triage of patients after a single case to make emergency preparations.

This system is dual-mode remote emergency triage system operations to provide voice communications transmission and GPRS communications transmission.

Traditionally, patients to the emergency room triage started doing the work of great need for 2 to 3 minutes and later to prepare the necessary first aid equipment and medical personnel, emergency room itself is messy noisy

environment, a large number of emergency patients give emergency room staff provided assistance to all flawless condition, so if from the ambulance to the triage process is complete classification of their disease, can be prepared in the emergency room to reduce the time required, whether to use voice input or remote transmission through the GPRS first aid can reduce the waiting time for patients, but now needs to complete a voice for about 106 seconds, the

recognition rate of about 94%, while the use of GPRS transmission requires 3 to 5 minutes, although all need a few minutes the time, but the process of using the time delivery of multiple use is the creation of the system.
