Real-time telemedicine system based on ADLINK MIX-110

For disaster relief operations or emergency medical services (EMS), time is more important than money because it is about life and death. An ambulance equipped with a telemedicine system is one of the best examples of mobile technology saving lives. On the way to the hospital, the ambulance can provide real-time patient information through wireless communication technology. It can also realize remote diagnosis and primary care, thereby greatly reducing the response time of rescue and winning precious time for further rescue of patients.

Telemedicine is a concept proposed by the American Telemedicine Association (ATA, American Telemedicine AssociaTIon). It uses electronic communication technology to exchange medical information from one location to another remote end, thereby effectively improving the clinical health of patients.

Telemedicine includes more and more various applications and services, such as remote health testing and medical education. In these applications, telemedicine-based ambulances use the most advanced automotive electronics and mobile communication technologies, which have obvious time advantages, can make critical treatment faster, and improve patient survival.

For example, when rescuing an injured person in a car accident, with the aid of the remote medical system on the ambulance, the vital signs of the injured person (such as ECG, blood pressure, respiratory rate, etc.) can be measured and passed through a wireless communication network (3G / Wi-Fi) to the remote hospital headquarters. In addition, the digital camera installed in the ambulance can shoot video and transmit it to the remote hospital in real time.

At the far end, doctors and nurses in the emergency room can use computers or mobile devices (such as tablets or smartphones) to receive and view the data collected from the ambulance and conduct a preliminary evaluation before the patient arrives at the hospital. The doctor in the emergency room can also enlarge the image to observe the patient's wound, discuss the treatment plan with the emergency medical ambulance personnel (EMT, Emergency Medical Technician) in the ambulance, and guide the emergency medical ambulance personnel to perform basic treatment and emergency medical services, such as injection Or provide treatment for fractures.

Emergency personnel and trauma doctors can also be remotely shunted for treatment. If necessary, the surgical team can be prepared before the patient arrives at the hospital. If they determine that the existing medical resources of the hospital cannot satisfy the patient, they can also recommend an alternative medical center to save time for transfer.

The goal of a telemedicine ambulance is to save every minute as much as possible to save lives. For stroke or heart disease patients, such a pre-hospital emergency system is very important. Early diagnosis and treatment can save the patient's life at a critical moment and reduce sequelae.

Telemedicine ambulances are also very valuable to residents in remote areas, because usually the patient ’s place of residence is still a long distance away from the hospital. Telemedicine ambulances can use radio communication technology for treatment and professionalization in advance Caregiver.

Application architecture

Ambulances based on telemedicine systems need to be equipped with a rugged computer platform to support multiple on-board wired and wireless devices (including medical devices) and provide wireless connection to remote hospitals.

Digital cameras must also be installed on ambulances to record how emergency medical services are managed and send real-time images of patients to the hospital. The microphone must also be equipped to facilitate the communication between emergency medical personnel in the ambulance and the hospital doctors.

It is also recommended to deploy GPS, so that the hospital can locate the location of the ambulance and provide the shortest route to connect the patient to the hospital for treatment as soon as possible.

In addition to a reliable hardware platform, advanced software is also necessary. Only in this way can a seamless and reliable connection be achieved when executing many applications.

The telemedicine system must be integrated into the hospital's outpatient information system, so that ambulance personnel on the ambulance, hospital doctors and nurses can obtain the patient's medical records at any time to speed up medical diagnosis.

In addition, the patient's latest physiological data and test results can be transmitted to the hospital's information system in real time, avoiding repeated examinations and treatments to speed up the patient's treatment.

Features

Remote patient monitor

The patient's vital signs data are measured on the ambulance and transmitted to the remote hospital for real-time monitoring and subsequent reference. These data include blood pressure, blood sugar, blood gas and electrocardiogram.

Real-time doctor "remote diagnosis and treatment"

Doctors in hospitals can make remote preliminary diagnosis and shunt decisions on the way from patients to hospitals through real-time voice and video transmission, and can prepare surgical equipment in advance if necessary.

Mobile emergency medical services and remote trauma treatment

According to the guidance of the doctors in the emergency room, emergency medical aid personnel can perform basic treatment and emergency medical services, such as injections or pre-treatment of fractures. The pre-stroke assessment and intensive care services can also be carried out in advance at critical life-saving moments.

GPS tracking

The vehicle-mounted GPS system can provide unparalleled accuracy in scheduling and navigation. The system allows the hospital to re-plan the optimal route to shorten the response time.

Electronic patient care report (e-PCR, Electronic paTIent care reporTIng)

The ambulance telemedicine system can transmit important ECG and other patient information to the hospital's information system in real time, establish or update the patient's electronic health report, avoid repeated detection and care procedures, save treatment time and save lives.

Expert recommendation service

Because the patient's information is available before he arrives at the hospital, the hospital can make a triage decision in advance and notify a professional doctor. If the existing resources of the hospital can not meet the current situation of the patient, the patient can be transferred to other hospitals or medical centers in advance to save time for transfer.

ADLINK Technology Solutions

ADLINK MIX-110 is a compact industrial computer (234.4mm x 191.2mm x 56.6mm).
