Based on wireless technology for next-generation medical video surveillance systems (1)

1, introduction

The use of advanced technologies to provide the most advanced and most timely and thoughtful services, establish a better image of the industry, and efficient patient care is the purpose of the medical industry.

At present, wireless network communication technology and image compression technology for rapid development, the security system and monitoring technical perfection and progress to build a new type of medical diagnostic care system. Particularly in telemedicine and medical monitoring applications, you can use the latest technology to build more adapted to the needs of teleconsultation, remote site monitoring, remote operation guidance, local regional intensive care, nursing care, emergency care, non-the-spot care monitoring system to complement and improve the existing medical monitoring means. WLAN (wireless local area network) technology continues to mature and perfect for a certain distance range building to wireless technology-based medical diagnostic care system possible. One based on wireless connectivity technologies WiFi IEEE 802.11 protocol family can in a certain space for medical images, data, wireless transmission, in particular the 802 .11n wireless technology is a wireless transfer HD image provides security, combining application interconnection agreements, DLNA, IGRS can implement various UPnP medical digital terminal equipment in particular removable device between the wireless identification, connectivity, networking and interconnection.

This article to WLAN wireless technology as the Foundation for future medical care diagnostic monitoring system, raised the application model and solution, an analysis of alternatives to traditional analog CCTV system and the possibility of digital DVR system, on the future of new medical diagnostic care system is described.

2, system design and implementation

With the increasing living standards, health concerns and requirements of the medical treatment is getting higher and higher.

From application demand, hospital outpatient, hospital building, security monitoring, Ward, care unit of intensive care for patients, operating 24 hours of surgery, doctors learn common consultation, etc., can not be separated from medical monitoring electronic equipment. In particular, the most direct application to a number of critical emergency wards and operating theatres and other places. The hospital is an urgent need to wards, operating rooms and other places for the primary monitor, on the operations and the ward patients as much as possible to implement real-time monitored. In this way, not only improves the efficiency of diagnosis and treatment, but also conducive to hospital standardized management, improve the patient's diagnosis, treatment and care, at the same time, the monitoring process videos save, help to resolve disputes, and blame.

Currently, most hospitals have been placed in medical monitoring system mainly wards call phone, video equipment, as well as alert e-mail button.

They constitute the current hospital medical monitoring system of the main frame, a point and a fixed monitoring features. The electronic monitoring device fixed installation mode of the medical diagnostic care monitoring system, with removable, randomly placed mode compared to medical treatment process may appear in various circumstances, has many shortcomings. 1, Ward is not enough, you cannot choose a random set placed temporary Ward; 2, new monitoring points, you cannot transfer to existing devices; 3, hospital information system is required for existing buildings chisel eye slotted wiring, construction process affecting its normal work; 4, wiring increase consumption and maintenance costs of wire rod. Using wireless technology to build medical diagnostic care monitoring system, you can avoid these problems, but also makes the hospital management, improve the environment.

2.1, next-generation medical monitoring system overall framework

Medical video surveillance system is a hospital information system, an important part.

Collected data for health policy and medical services. Video images of the patient record, preserve the maximum amount of data. From the simple call to the live transmission of video data, operation monitoring, remote consultation, bracelet, SMS, constitute a solid medical monitoring network. As shown in the figure.
