Remote Monitoring Solution


Author: Wang XingHong

With the development of science and technology, monitoring is needed not only inside hospitals. Traditional doctor-face-to-face-with-patient diagnosis no longer satisfies peoples increasing demand of health care and it also needs improving in the usage of time and resources, which is a huge challenge to medical care industry. Luckily, wearable physiological detection technology emerges in the right moment. It can not only monitor for a long and continuous time, but also display user’s health condition and physiological information in real time, which helps doctors to regularly monitor users and conduct remote diagnosis.

Remote monitoring technology is a hot spot in recent tele-medical research and also a relatively weak link. Western countries are researching remote monitoring all along and China also starts to develop this technology in recent years. Remote monitoring can be defined as a mean to transmit physiological information and medical signals via communication network to monitoring center for medical workers to analyze and diagnose. Remote monitoring system generally contains three parts: monitoring center, remote monitoring devices and communication network. According to the requirements of Hunan Xiangya Hospital, Comen put forward the following solution:

1. Remote monitoring devices

According to monitoring subjects and purposes, there are various types of devices. They can be divided into three types based on their functions.

The first category is detecting and remote monitoring system for physiological parameters, such as Comen’s ECG machines, monitors and fetal monitors. This type of devices are the most widely used, which can help doctors learn the conditions of the subject and provide timely medical instruction. Physiological information monitored includes ECG, EEG, HR, BP, PR, RESP, SAP, SpO2, TEMP, GLU etc.

The second category is monitoring devices for daily activities, such as living facilities used in daily routines and when the subject is at active state like sitting, lying down and walking, mainly used in children, elder people and the disabled.

The third category is monitoring devices for nursing patients, such as urine monitoring device for paralyzed patients, which can save nursing staff lots of work.

2. Monitoring center

Monitoring center can be set in emergency center, social community hospital, central hospital and other places which gather medical workers. Its purpose is to receive medical information transmitted from the remote monitoring devices so as to provide multiple medical services to the faraway patients.

3. Communication networks

Communication networks that connect the monitoring center and the remote monitoring devices mainly include public switched telephone network (PSTN), interactive TV (ITV), integrated services digital network (ISDN), asymmetric digital subscriber line (ASDL), asynchronous transfer mode (ATM), microwave communication, satellite communication, cellular radio communication (global system for mobile communications [GSM]) etc.

Technologies supporting remote monitoring include sensor technology, medical telemetry technology, electronic technology, communication technology, computer technology and informatics etc.

Database selection

Oracle/SQL Servers are for you to choose based on user scale and maintenance ability. The built-in database engine can control right to access and process data quickly. Search engine can index data in the database, support inquiry under multiple conditions and response very fast. It is convenient to manage firewall logs and access to rules. It also facilitates database administrators and developers to manage database and write relevant SQL statements.

Devices selection for monitoring center

Monitoring center is mainly used by medical workers. One host can have four displays (16 patients each) so that 64 patients’ information can be seen at the same time.
