A wireless sensor technology' application in clinical nursing of hospital internet of things

ABSTRACT

Background: With the continuous development of sensing technology, people begin to use all kinds of sensors to monitor the human condition, such as early rising ECG instrument. Although this kind of equipment has the characteristics of high precision and high sensitivity, it has the defects of large volume, high power consumption, harsh use conditions and high cost. With the continuous development of wireless sensor network technology and integration technology, it is more and more possible to design a device with small size, high mobility and greatly reduced cost on the premise of maintaining the advantages of dual height. The purpose of this study is to explore how to apply wireless sensor network technology to clinical field, and to study the exact benefits of wireless sensor network technology for clinical neighborhood. Methods: Body temperature is an important monitoring index of whether there is abnormality in human body. Taking this as a breakthrough, we designed a real- time temperature acquisition device that can be worn on the arm of patients for a long time by using wireless sensor network technology and high- sensitivity sensor (sensitivity < 0.1°C). In addition, in order to complete the normal transmission of body temperature data, we also designed data aggregation node, gateway node and data processing platform. Through the system, the patient's temperature data can be monitored by the medical staff in real time. Results: Compared with the traditional methods of body temperature measurement (mercury thermometer, infrared thermometer), With the same accuracy, it can record the patient's temperature change in more detail (usually the temperature measurement in the hospital is tested every 6 hours, while the system can be tested every 30 minutes, 1 hour and 2 hours, and the test interval only needs to be completed through the system setting). The use of the system can greatly reduce the workload of medical staff (from the perspective of temperature measurement alone, it subverts the traditional way of temperature measurement, from a way of medical staff to a way of patient to a way of system automatically recording the patient's temperature data, which can be viewed by medical staff when they need to), and it can realize the non- contact temperature monitoring between doctors and patients, which can control infectious diseases such as SARS, novel coronavirus is of great significance Conclusions: The combination of sensor technology, low power consumption technology, integration technology and wireless sensor network makes it possible to realize medical grade physical examination equipment with high precision, long time and easy to carry. This kind of equipment can greatly reduce the nursing workload of medical staff for patients. Reliable and accurate data also provides powerful data support for the treatment of patients later.
