Wi-Fi technology realizes new medical monitoring system

Introduction

In recent years, the widespread application of information technology in various fields has brought great convenience to people's lives and production. In particular, its application in the medical field has reduced the workload of medical workers, improved the level of medical care, and reduced the burden and pain of patients. More importantly, it has brought about a series of medical models and promoted the development of the medical industry. For example, the increasingly mature hospital information system and telemedicine system are constantly updating people's impression of medical care.

At the same time, the highly developed electrical technology has enabled more and more patients to have small diagnostic and treatment equipment corresponding to their own conditions, such as elderly monitors, blood pressure monitors, blood glucose meters, etc. However, at present, personal diagnosis and treatment has always remained in an independent and closed state, and information technology has not been fully utilized. Therefore, almost all patients face the following problems:

(1) When encountering some physical abnormalities or even emergencies, they cannot get timely professional guidance and assistance;

(2) It is difficult to accurately record the data fed back by the treatment equipment for a long time;

(3) It is impossible to scientifically analyze the data recorded by themselves and it is difficult to detect changes in the condition.

In view of the above problems, combined with the development of current information technology and wireless transmission technology, information technology can be applied to personal medical equipment through WIFI technology, and the Internet and social medical resources can be integrated to establish a new community medical information system for patients and around patients.

1 WIFI technology

WIFI stands for Wireless Fidelity, also known as the 802.11b standard, which is an industrial standard for wireless network communication defined by IEEE. This technology uses a frequency band near 2.4GHz, which is currently an unlicensed wireless frequency band. Its main features are: fast speed, high reliability, and a communication distance of up to 305m in an open area and 76~22m in a closed area. It is convenient to integrate with the existing wired Ethernet network, and the cost of networking is lower.

2 System Description

2.1 Implementation of Wireless Transmission

Since the WIFI of this system is used in a mobile monitoring system, it can be called embedded WIFI. The structure of embedded WIFI is different from that on the standard PC/OS platform. To implement WIFI communication on an ordinary microprocessor/microcontroller, its hardware structure and software level must be tailored. Here we use a perfect WIFI module, and the software level tailors the protocol as needed to adapt to embedded requirements. Because the system uses embedded WIFI technology and supports digital grouping, it can group the objects under test as needed and transmit real-time data at the same time; it ensures the reliability and accuracy of monitoring and has a good effect in actual use.

2.2 Implementation of remote monitoring

The function of the entire system is to collect, analyze, and process the physiological signals returned by the monitored users remotely. The above-mentioned WIFI technology is used to connect the entire user end to the remote medical system. Although there are many user signals collected here and the amount of data is relatively large, the current high-capacity channel of WIFI can fully handle it. At home, we can use a wireless router, and WIFI can directly connect to the Internet; and outside, as long as there is WIFI coverage, users can also access it for a fee or for free, so as to upload the signal through the Internet. From then on, the cost of running the system is very low and it is also very reliable. Moreover, with the development of modern society, more and more cities have achieved "city-wide wireless coverage", and the scope of use of this system is becoming wider and wider, and the effect it produces will become greater and greater.

When data is transmitted to the medical system, we use IBM's high-end servers, which can adapt to large amounts of data throughput and store and back up data. Connected to the server are several minicomputers or PC terminals, which can access or analyze the data in the database and perform routine operations, and can also take corresponding measures (such as alarms, suggestions, etc.) on the processing results, so that remote users can be monitored or diagnosed.

2.3 Implementation of data transmission

This system uses personal medical equipment with communication functions to collect patient vital sign data, and then transmits the data to the community medical center, which stores and performs real-time analysis, and then feeds back the analysis results and doctor's instructions to the patient through the mobile terminal, completing a complete information exchange.

This system is divided into two components: personal health real-time monitoring equipment and network information transmission.

(1) Personal health real-time monitoring device

This component collects various health indicators of the human body (blood pressure, pulse, etc.) through peripherals and stores them in the storage element inside the instrument. The CPU of the instrument then analyzes and organizes the user data and stores the conclusions drawn;

(2) Network transmission device

This part extracts and transmits the data stored in the memory to the terminal in the jurisdiction of the instrument, and transmits the conclusions drawn by the terminal to the user's monitoring device in a timely manner. The beneficial effect of this system is that it can collect patient vital sign data, conveniently transmit the data to the community medical center, store it and complete instant analysis by the center, and feedback the analysis results and doctor's instructions to the patient through the mobile terminal, which is convenient for medical institutions to monitor and record patients at all times, and has a simple structure.

3 Conclusion

This system embodies the humanistic spirit of science and technology caring for life, and will inevitably show its unique advantages in the deepening medical reform. It completes the full-time and individualized medical care, realizes the all-weather monitoring of individual patients, makes the medical force spread to every individual in society, and strongly guarantees the concept of health first and life first. This system

has a good development prospect, which can be reflected in two aspects:

1. This system represents the future development direction of medical care, conforms to the latest spirit of medical system reform, and has good policy support;

2. Related industries such as network operation and hardware market are mature and have many existing resources that can be used.

The key to the success of this system lies in the good integration of various social resources and the establishment of good cooperative relations between companies and communities, governments, hospitals and large mobile operators. To establish a good cooperative relationship, the key lies in establishing and improving various cooperation plans and improving the value of services themselves, optimizing the resources of all parties and striving to promote the maximization of interests of all parties.
