Description

System for providing emergency telemedicine for ships using international maritime satellites {a system providing a remote emergent medical examination for a ship in using a marine satellite}

The present invention is a system that can be used for medical treatment of patients in remote medical institutions using basic bio signals, video images and audio such as ECG, NIBP, blood oxygen saturation, pulse rate, respiratory rate, etc. It is intended to improve the poor medical environment of ships at sea.

In the present invention, it is composed of a system for controlling and integrated management of a remote system for ships, a remote system for medical institutions, and a biosignal measurement equipment so that the patient can be remotely diagnosed between the ship and the medical institution by transmitting various biological signals capable of detecting the patient's state. When applied to ships, it is possible to efficiently transmit important medical information even at low transmission speeds of the International Maritime Satellite, which can prevent the ships from sailing in the event of an emergency and can save significant costs. Accurate prescriptions can be made to provide advanced medical services.

The development status of remote medical devices in Korea has been developed for the silver industry and home remote medical devices, but there is no development of remote medical services for marine vessels. The construction of the Internet or wireless infrastructure, which is essential for telemedicine and home health care, is progressing so rapidly that it cannot be found anywhere in the world. The production technology of bio signal measuring system has reached the level of advanced countries in terms of function, but the development of miniaturization and wireless low power type measuring system is still insufficient. It is essential to develop an information system that automatically handles many tasks for the dissemination of remote and home medical care. Since this field is in the early stage of development in the world, if you start early, you will have an advantage.

At present, there are no remote medical devices in the ocean at home, and introduce home remote medical devices, patient monitoring devices, and network medical service systems. As home remote medical devices, Elbio's Webdoc and Telemed's HelloDocs measure various biosignals such as ECG, NIBP, SpO2, blood alcohol concentration, body fat analysis, blood sugar, electronic stethoscope, and body temperature at home. Transfer, save and manage to the computer connected to the network. In addition, the physicians are required to report the test data, diagnose the test result and notify the tester. Monitoring equipment from Mek, Madison Devices have been developed to monitor ECG, SpO2, non-vascular blood pressure, body temperature, respiration, and pulse rate. The systems of these companies are also suitable for moving ambulances or in-home care, and there are also devices that can be used for a long time. In the network medical service system, an online virtual hospital where an appointment of a medical institution online, a virtual medical treatment, or a prescription thereof is performed, is performed by a medical examination or a remote medical device. Representative examples include the Department of Family Medicine, Seoul National University Hospital (http://mydoctor.snu.ac.kr/telehomecare), Medidas-Healthsem (www.healthkorea.net), Hanmedi (www.hanmedi.com) and Dr.Cregio (www. drcrezio.co.kr).

Let's look at the domestic technical level. The level of core technologies related to remote medical devices in Korea are the same as in FIGS. 28 and 29. (Korea Electrotechnology Research Institute, Silver Medical Devices PM, 2004, 3. Excerpt)

Fig. 28 shows the level of domestic technology relative to developed countries related to remote (home) medical devices, and Fig. 29 shows domestic and foreign comparisons of key technologies related to remote (home) medical devices.

Next, consider Germany. In Germany, the Marine Remote Medical Center (RMA) provides professional medical services 24 hours a day, 365 days a year. All doctors directly provide medical responses to emergencies. Digital photo transmission has been available since 2000. Recently, video image transmission methods such as 12 lead ECG, NIBP, CO (2), blood oxygen saturation, pulse rate and respiratory rate have been developed. The system provides world wide communication using GMS or international maritime satellite (ISDN or Iridium) satellite transmission. Recently, the system was installed on a SAR rescue boat in Germany.

In Greece, MERMAID, an EU-funded project for the maritime telemedicine project for the health of multinational crews in the world's oceans, was carried out based on video conferences using ISDN, as well as medical treatment in the absence of doctors. To make it possible. It is built from satellite to infrastructure system in ships and can call specialists from all over the world using broadband network.

In Spain, all seafarers receive the same medical services under the “Maritime Health Program.” Mariner's Social Institute, established in 1919, provides medical advice on ships and medical services for marine workers. In Madrid, there is a Radio Medical Advice Center, which is located in the port to enable the exchange of hospitals and centers.

In the United Kingdom, the National Health Service offers remote medical services via wireless LAN. The development of telemedicine devices in the ship-to-shore concept.

In the U.S., the Department of Defense is the mainstay of telemedicine, which brings a wide range of benefits in terms of accessibility and cost (extracted from PubMed).

Trauma is the main cause of disease in marine vessels, but the range is very diverse. The present invention allows a more accurate prescription by allowing a patient to diagnose a patient's disease after checking the patient's basic condition (blood pressure, pulse, respiration, electrocardiogram, body temperature, imaging, etc.) rather than medical advice by simple questions and answers. It aims to be able to provide medical services.

Currently, the era of high-speed information communication network is coming, but the external communication means in ships that operate for a long time through the sea depends on the international maritime satellite, and the basic condition information of the patient is smoothly transmitted to the remote doctor in the limited environment of low transmission speed. There is a need for a system that allows transmission to allow for diagnosis of the patient. Therefore, another object of the present invention is to develop a system capable of remote medical treatment based on a basic state received within a limited bandwidth.

5 shows a measurement module and a user interface of a remote instrument. As shown in FIG. 5, the biosignal measuring unit is a core module commonly applied to all service models, and measures electrocardiogram, respiration, non-invasive blood pressure, arterial saturation, and body temperature. The ECG module is output as a 1-channel limb-lead waveform, the Respiration module is output as a 1-channel respiratory waveform and respiratory rate, and the noninvasive blood pressure (NIBP) module is a systolic / diastolic / average blood pressure. Output, the arterial saturation degree (SpO2) module is output to the light-only red-wave waveform and oxygen saturation, the temperature module (Temperature) module outputs the body temperature.

Respiratory monitoring is sensed through ECG leads, so that signals are digitized and displayed on the screen by a 12-bit A / D converter without attaching a separate sensor. 6 is a PC-based remote instrument.

Bio-signal measurement module integrated management unit (bio-signal measurement unit) is integrated management of the measurement module for integrated management of the signal value measured from each bio-signal measurement equipment to output to the monitor. Among the data used in the biosignal measurement module integrated management unit, ECG, ECG, and pulse, which are automatically measured by the biosignal measuring equipment, are sampled and output as shown in FIG. The value SpO2 (oxygen saturation) is entered automatically, and the Temperature and Glucose are entered directly.

When the signal measuring equipment is connected to the remote control system for ships by cable under heavy vibration conditions such as ships, noise is generated in the data received through the cable due to the ship's vibration, which makes it difficult to acquire stable signals. In order to obtain a stable signal, the connection between the signal measuring equipment and the ship's remote system controller is wirelessly transmitted using Bluetooth to minimize data noise.

The biosignal measurement module integrated management unit (biosignal measurement unit) is Windows XP SP2, the framework is .NET Framework 2.0, and the programming language is implemented in C # and C ++.

Hereinafter, the Data Library will be described in order to describe the implementation in detail. To understand the Data Library, let's look at the signal structure definition. As shown in FIG. 8, the structure for the signal input from the device is designated as DeviceSignal, and ClinicalSignal and EventSignal are converted for network transmission. Signals used in this system can be classified into three types. It is a general signal measured in the measurement module, an event signal input whenever an event occurs, such as respiration and blood glucose levels, and a raw signal from the device. Signal type classification is as shown in FIG. 9. The state of blood pressure equipment and oxygen saturation measuring equipment to indicate the state of the biosignal measuring equipment is defined in advance. 10 shows the definition of the state of the biosignal measuring apparatus.

Next, let's look at the Data Library class diagram. The TimeStamp class is a part of the time stamp on the data. It is added to atomic data and used for network and drawing. The Buffer Thread class handles hardware and buffers for storing atomic data during network transfers. The necessary thread buffer uses a template from a list. The filter class is a filter for calculating the average value of data. 11 shows the structure of time stamps, butter threads, and filter classes.

Looking at the signal class, DeviceSignal class obtains ClinicalSignal and EventSignal from atomic class DeviceSignal of raw data input from hardware and delivers them to network, file and screen. The ClinicalSignal class defines 0.1 seconds as the signal unit. ECGs import 30 samples at a time, NIBPs, SPO2, and PULSE 10 sample data at a time. (ClinicalSignal is the atomic object of the pulse biosignal.) The EventSignal class includes NIBP, SPO2, Temperature, and Glucose. Keypad events are also treated as event signals. Update once every second or whenever an event occurs. 12 shows a structure of class information for each signal. After defining the biosignals by type, the raw signals from the measurement module are stored in the buffer, and the signals are taken from the buffer to divide the signals by the measurement module by type.

Next, let's look at the main interface of the integrated device for ship emergency. 13 shows the main control interface unit of the integrated device for ship emergency. The main control interface of the integrated device for ship emergency is an interface to control the operation of the biosignal measurement equipment, which is hardware in the integrated device, and is a user interface included in the remote medical S / W for ship emergency. And a part for controlling the state. It is an interface that anyone can use if the size of the button is large and the user knows how to operate it.

Blood pressure is measured using a measurement button and oxygen saturation and respiratory readings are automatically activated when the device is attached to the patient. In the case of temperature (body temperature) and blood glucose, there is an automatic measuring device. However, since the error of measurement value is large, it is relatively inaccurate compared to manual measurement, and even small errors can affect the patient's diagnosis and prescription. It was developed to measure the blood glucose and input the value. The development environment of the main control interface of the ship's integrated device is Windows XP SP2, the framework is .NET Framework 2.0, and the programming language is implemented in C # and C ++. The hardware control of the biosignal measuring equipment used in this study is written in C ++ and connected to the user interface in C # to control the hardware.

The biological signal measurement analysis and algorithm will be described. In order to measure bio signals for each module, equipment connection and data are first received. Communicate with the device's USB module. Data transmission to the device uses a function (recorded in the send-related functions-header), and reception uses a thread. In addition to receiving, the thread checks whether the communication function of the device survives, retransmits in case of error, and also receives the device configuration data (ECG_Amp1 ~ 3). Received data is organized and queued, and the main dialog class (here C blood pressure meter Dlg) is informed whether or not it is received using the user-defined message WM_QUEUE_FILLED. In the main dialog class, the received data is received using the BLU_cont.Read_Queue () function at the place where the WM_QUEUE_FILLED message is received, and the device is opened, and the ECG_Amp1 to 3 values are processed.

Let's look at signal analysis and processing. First, for the biosignal filtering, the average of the number of samples is calculated and the data is stored in the buffer. It is used to remove the offset of ECG / breathing through filtering. However, since a large signal is considered to be not related to an offset, a value above a certain threshold is ignored. The filtered signal is received by the biosignal measurement module.

Let's take a look at the remote medical care S / W part for ship emergency (ship remote system control unit). Bio-signal measuring equipment, image camera, and micro-inputted information are converted into data type suitable for TCP / IP communication in each module to transmit to remote medical S / W of medical institution.

ECG, ECG, Pressure, and Pulse, which are automatically measured by the biosignal measuring equipment in the vessel, are sampled as shown in FIG. 30, and the data is automatically output. As other numerical values, SpO2 (Oxygen Saturation) is It is automatically converted into numerical values and the Temperature and Glucose should be entered directly from the vessel. A biosignal data structure is illustrated in FIG. 30.

In ships, the measured bio-signals are stored in the database file by the time the signal is measured and by the type of incoming data. The database file creates a file by designating a file name with the date and time of the day and the identification number of the ship each time the remote medical service S / W unit for the emergency is executed and stores the measured signal value.

25 is a configuration diagram of the remote medical care S / W part for ship emergency. Chat messages are sent and received by doctors, and audio, video, and image (Snapshot) messages are sent and received. The biosignal transmits three ECG channels: Pressure, Pulse, SpO2, Temperature, and Glucose. The structure of the data sent from the medical emergency remote medical care S / W to the medical institution remote medical care S / W is shown in FIG. Data is sent first by priority, and still images, texts, and other notification signals are transmitted in a flexible size within a range of 40 Kbps. Since the International Maritime Satellite supports low bandwidth, it is composed of a structure that can send as much data as possible.

The remote emergency S / W for ship emergency delivers the patient's information using the developed S / W and various biosignal measurement equipment in front of the laptop, the image cam for video, and the microphone in the laptop itself. Fig. 14 shows a ship emergency system in which a remote medical care S / W unit for ship emergency is installed. The remote medical emergency S / W for ships was designed for Tablet PCs that can be used with on-screen touchpads to accurately perform various tasks even within a ship.

The main screen of the remote medical care S / W unit for emergency is as shown in FIG. When the remote emergency medical service for ship emergency is operated and the biosignal measuring equipment is connected, the plug-shaped icon between the video screen is changed to the connected state, and when the connection is normally connected to the international maritime satellite network, the broken icon of the network is connected. It will be changed to form. Buttons exist on the screen interface to turn on / off patient information such as various bio-signals, images, and voices. This function turns off unused functions in consideration of the limited transmission bandwidth of the international maritime satellite. The targets of the On / Off function are continuous biometric information, images, audio, and photo information, in which a lot of data are generated. There is an emergency button to inform the imminent situation of a ship, so when a user presses a button, the doctor can monitor the ship.

When accessing to the doctor from the ship, the address of the computer running the remote medical S / W unit for the medical institution, which is basically entered, is entered. If the user is connected to the doctor by entering the identification number of the current vessel, the remote medical S / W for the medical institution The department can check whether the ship is connected. As shown in FIG. 16, in the graph on the left, the ECG channel, the pulse (pulse), and the respiration (respiration) state are outputted while the waveform is drawn, and when the + and-on the graph are touched, the waveform of the graph is displayed. The Y-axis is enlarged and reduced. As shown in FIG. 17, the state of the doctor and the current vessel are output on two image panels located on the right side, and an icon indicating whether the measurement equipment is connected to the network is located next to the emergency button. When the button next to the blood pressure reading window is pressed, the blood pressure measuring device starts to operate. If the blood pressure measurement is measured without error, the blood pressure reading appears in the reading window and an error message appears if an error occurs. As shown in FIG. 18, by pressing the Speech On button at the bottom right of the main screen, the doctor can be notified of the current state by voice, and a simple chat can be performed using text. As shown in FIG. 19, the body temperature and the blood sugar are displayed by clicking a button of the body temperature and the blood sugar in the numerical display portion to display a numerical input window and input the measured body temperature and the blood sugar respectively.

As shown in FIG. 20, when the upper panel is selected among the image panels, a screen for taking a snapshot is displayed. The still image may be stored and transmitted to a doctor by a camera installed in the vessel. The ship's video can be turned on and off with the On / Off button above the top panel, but the ship's video cannot be controlled on or off.

Next, let's look at the remote medical care S / W department for medical institutions (remote system control unit for medical institutions). 26 is for medical institutions This is the configuration of remote medical S / W unit. Telemedicine S / W for medical institutions is basically connected to the Internet, and telecommunications operators operating the international maritime satellite used by ships can communicate remotely by supporting TCP / IP. It classifies the data coming through the network and displays it on the remote medical S / W for medical institutions. The doctor will look at the vital signs and measurements and understand the condition of the patient on board the vessel and instruct them to take appropriate action by voice or text.

Basically, it is possible to communicate with ships by telecommunication operators operating international maritime satellites supporting TCP / IP. It classifies the incoming data through TCP / IP and displays it on the remote medical S / W for medical institutions, and the doctor sees the bio-signals and various measurement values to understand the patient's condition and directs the appropriate prescription. The telemedicine system for medical institutions does not need any special equipment, and if there is a PC, image cam, microphone, etc. with general internet access, information from the ship can be checked.

21 is an execution screen when the remote medical care S / W for a medical institution is executed. 22 is a user interface of a remote medical care software for medical institutions.

The S / W created to allow the doctor to check the patient's status information and the ship's status from multiple ships is as follows.

When the remote medical service S / W for ship emergency is connected to the remote medical S / W for medical institutions to transmit data, the doctor can create a session on the doctor's PC to find out which vessel is connected. Since the remote medical S / W for medical institutions is basically installed in a hospital or medical center and used in a desktop environment, the basic interface is designed to be controlled by a mouse. In the same way as the remote medical treatment S / W part for ship emergency, the output of the graph is expanded and reduced based on the Y axis.

The doctor does not have the function of inputting various figures and can simply see the figures coming from the ship, and the image panel where he can simply display his own image and the image of the vessel is located on the right side of the main screen. The basic interface is the same as the remote medical service S / W for ship emergency, but the remote medical S / W part for medical institution does not have the control button of the biosignal measurement module, and it is implemented to monitor the waveform and value of the signal.

Fig. 23 shows a state of confirming a patient state using a remote medical care S / W unit for a medical institution. The doctor side is a platform that can transmit only voice, video, and input text, and a list of ships connected to the doctor is created in real time in the left list, and if the ship in this list is selected, the information is converted to the information of the corresponding ship.

27 is an operation screen of the system for remote medical care. Multi-access to remote medical care S / W for medical institutions enables one doctor to see several patients. The ship icon in the list will flash and the Emergency button will flash and an emergency beep will sound. The emergency function can be used to immediately change the situation of a ship requiring a doctor and make a diagnosis. The Beep button at the bottom of the list makes it possible to flash only the icon without sounding the alarm when the emergency button is pressed on the ship.

Next, let's look at the biosignal processing method of the system for providing emergency medical care for ships using the international maritime satellite (200). 4 illustrates a biosignal processing method.

Biosignal processing method of the present invention is the first step (S110) for connecting the biosignal measuring equipment to the ship remote system 100, the second step (S120) for receiving the setting data of the biosignal measuring equipment, and the biosignal measuring unit And a step (S130) of filtering the biosignal by removing the offset of the biosignal sample measured in the storage unit 170 and stored in the storage unit 170, wherein the biosignal has a certain period of time in which the biosignal is vibrated under a special condition with high vibration. It is a biosignal processing method of a system for providing emergency medical care for ships using the international maritime satellite 200, characterized in that detected during.

Finally, looking at the economic and technical effects through the present invention, the effect of the technical aspect is to secure the sensor and signal amplifier technology that can detect a bio-signal under special conditions with a lot of vibration of the ship through the improvement of the technology, the international maritime It is possible to secure medical information transmission system technology using satellite satellite system, to develop signal compression technology for multimedia communication, to miniaturize biosignal measurement module and secure unconstrained measurement technology, and to establish a marine remote medical system.

The ripple effect of other technologies is that miniaturization and wirelessization of the biosignal measurement module can contribute to related research such as medical engineering and physiology by providing the convenience of biosignal measurement, and the remote medical system using the international maritime satellite system provides disaster and disaster rescue. It can be used for the system, and it is possible to secure the base technology of the land and air mobile telemedicine system.

According to the Shipping Statistics Manual, more than 1,000 tons of ships sailing around the world amounted to 35,000 ships in 2002 and 45,000 ships in 2005. In Europe, satellite telemedicine is being introduced and related products are on the rise, but are still in the early stages of entry. Therefore, if the development of a competitive product is successful, it is predicted that the global ship will be sold.

Even if a marine remote medical system is introduced in Korea, there is no product made in Korea at present, so there is no choice but to rely on imports. However, if the ship's telemedicine system is mass-produced with domestic pure technology, import substitution can be effected. Competitive products look forward to worldwide sales. The global telemedicine market is still in the introductory stage, so if we have technological competitiveness, we will be able to develop the global market. This requires active investment in this.

In ship emergencies, the introduction of a remote telemedicine system can reduce costs due to the return of ships, the delay of time, and the misuse of drugs. For example, data from 1339 Busan Metropolitan Emergency Medical Center, cost analysis of 43 out of 53 cases between January 1, 2003 and May 30, 2004 resulted in a cost loss of US $ 2,283,773. In addition, the existing emergency medical treatment method is limited to a method of transmitting a picture using a telephone, a facsimile, or a digital camera, and causes an inefficiency of time delay. In an emergency that is directly related to life, shortening of time and accurate first aid are most important, and accurate first aid requires doctor's instructions to determine the patient's condition. To this end, it is necessary to develop a remote medical device that can send vital signs, basic data and photographs in a timely manner.
