Telemedicine is the application of computer network technology in the medical field. With the rapid development of computer network technology and information technology, telemedicine systems have received extensive attention. Detailed analysis of the telemedicine consultation activity process, designed a B / S mode-based telemedicine real-time consultation program, and using 1N ET technology to achieve remote diagnosis, consultation, online guidance and other functions. Tests show that the system is simple and convenient to operate, easy to maintain and manage, and can complete the consultation work well. Telemedicine is the product of the combination of network technology and medical technology. Today, with the rapid development of information, it has become a beautiful landscape in medical communication. Telemedicine is the use of information and telecommunications technology to exchange medical clinical data and expert opinions of patients who are apart. It is the use of computers, communications, medical technology and equipment, through the long-distance transmission of data, text, voice and image data, to achieve the "face-to-face" consultation between experts and patients, experts and medical staff. The concept of a telemedicine system was originally proposed by the United States. An open telemedicine system usually includes: remote diagnosis, expert consultation, information service, online inspection and remote communication. It is based on computer and network communication. , Realize the transmission, storage, query, comparison, display and sharing of medical data (including data, text, pictures and audiovisual materials) and remote video and audio information. At present, in this field, the United States and Western European countries have developed fastest, with a history of nearly 40 years. China started late, and modern telemedicine activities only began in the 1980s and have only received attention and development in recent years. In this paper, a detailed analysis of the telemedicine consultation activity process is carried out, and a real-time telemedicine consultation solution based on the B / S mode is designed. The 1NET technology is used to realize the functions of remote diagnosis, consultation and online guidance. 1 The overall system design and technical methods adopted The choice of system architecture mode is crucial in an application. If not properly constructed, it may lead to increased complexity and inefficient applications. The system architecture mode has client (Clien t) / server (Server) mode, that is, C / S mode or fat client; browser (Browser) / server (Server) architecture mode, that is, B / S mode or thin client. The B / S structure (Browser / Server structure) is an improved structure for the C / S structure with the rise of Internet technology. The biggest feature of the B / S mode is: users can directly access the text, data, images, animation, video and sound information on the Internet through the WWW browser without installing any client program. In addition, the B / S mode also has Use, development, business expansion, simple and convenient maintenance, strong sharing, etc. Under the B / S structure, the user operation interface is implemented through the WWW browser. The front end (Browser) only contains a very small part of the transaction logic. The main transaction logic is implemented on the server side (Server), which concentrates all Development, maintenance and upgrade work, thereby simplifying the client software, users only need to install a browser as their operating platform. The client uses a browser to access the Internet, makes a request to the Web server, the Web server processes the request, queries the database, and then organizes the queried information into HTML pages to be returned to the user and displayed on the user's browser, thereby forming a B / S mode of three-layer structure. Therefore, the use of B / S mode is more in line with actual application requirements. The B / S structure diagram is shown in Figure 1. This system uses Visual Studio 2008 as the development platform, uses C # language to complete system development, and uses SQL Server 2000 large-scale relational database management system to manage the storage and archiving of background image information, as well as medical history data, medicine and management information. Store. C # (C Sharp) is a programming language tailored by Microsoft for 1N ETF ramework. C # has the powerful functions of C / C ++ and the features of easy use of V isual Basic. It is the first component-oriented (Component- oriented programming language, like C ++ and Java is also an object-oriented programming language. Since Visual Studio 2008 integrates many languages ​​in one, it is convenient for the communication and inter-operation of interfaces between languages. In addition, Visual Studio enables developers to use ASP.NET AJAX's seamless integration and familiar programming model as well as Internet Explorer browser extensions and enhancements to easily create more interactive, more responsive and Web application with more efficient client execution capabilities. 2 Realization of telemedicine real-time consultation system 2.1.1 Consultation work mode In the telemedicine system, the working mode of consultation can be divided into non-real time consultation and real-time consultation. Non-real-time consultation is a remote medical expert's non-real-time diagnosis of remote patients by viewing the patient's medical records, including text, pictures, voice, and image data. Patients and consultation experts can conduct remote medical consultations or consultations via e-mail or other methods. This consultation method is not limited by time, does not require the presence of both parties at the same time, and does not require high real-time network transmission. With greater flexibility, it is ultimately up to the consulting specialist or hospital to make the diagnosis and determine the treatment plan. Real-time consultation refers to the patient or family members and the patient's attending doctor and remote consultation experts through various video conferencing systems or camera devices to conduct "face-to-face" remote real-time consultation and even surgical guidance and other medical activities. Through this face-to-face communication, both parties and even multiple consultation experts can use the same patient consultation data for remote consultation at the same time And the personnel of all parties to the consultation can use voice and video devices for real-time dynamic communication, discuss together, and finally determine the result of the consultation. Compared with non-real-time consultations, real-time consultations have certain requirements for the real-time nature of network transmission, but for this reason, the communication of consultation experts is more real-time interactive, and it can achieve clear, intuitive, accurate, and fast communication effects. Therefore, the treatment efficiency is effectively improved, and it has strong practical application.
NTC temperature surface mount sensors are non intrusive type sensors consisting of a probe section designed for mounting to flat or curved surfaces.
Cables can be supplied with insulation or jacket in PVC, Teflon or Silicon. Some cables are also available with a stainless steel over-braid or stainless steel armor for additional protection.
With the properties of easy installation, surface temperature measurement, surface mount type NTC Temperature Sensor has been used to power supply, radiator, electric motor and generator. Temperature range is from -30°C to 105°C.
