Development Of Infrared Infusion Alarm System

Intravenous infusion as a route of administration, more and more applied to clinical medicine, but, as among the widespread use of intravenous infusion, its inconvenience are gradually revealed.Medical personnel need to observe two kinds of infusion information during the infusion processes, it includes the speed and if the infusion is finish or not. The transfusion speed is determined by the illness, transfusion amount, and infusion purpose and medication profiles. Infusion too fast or slow is possible to causes the patient discomfort even endanger their life. After the infusion patient requires immediate treatment by medical care personnel, it will damage the life and health of patients if the treatment is not timely. But intravenous infusion is a lengthy process, easy to make patients and medical care personnel produces negligence, not timely find and deal with the situation mentioned above, will increased medical accidents hidden trouble.Infrared infusion alarm system is developed to solve the problem, reduce medical staff's intensity and protect the patient's life and property.Infrared infusion alarm system's main function is to infusion processes of transfusion speed monitoring and the alarm of improper speed and the end of the infusion. The system is compromised by the nurse station host and ward extension. The ward extension acquisition and processing infusion information by infrared sensor, using wireless sent the information to the nurse station host, nurse station using computer software to host real-time display infusion speed, when the speed value overrun or infusion end for the police. Make medical care workers can timely handling the situation. PC software is also the patient information management system, convenient for patient information medical personnel management.The core of infrared infusion alarm system is made up of STC89C52RC, contain wireless communication module, USB communication module, human-computer interaction module and other major modules. Wireless communication module chose the Nordic companies nRF24L01 as the core chip, the chip works in 2.4 GHz international general ISM frequencies, less component with peripheral, development easy low cost etc, and can be through replacement of antenna improve the performance of the system, facilitate system upgrade; USB communication module chose homebred CH372, high performance, stable work. PC software development is using Visual C++ 6.0; realize the infusion of the process of monitoring and patient information management. Infrared infusion alarm system has the characteristics of high performance, low cost and can easily according to the actual situation of system upgrades, has strong market competitiveness, suitable to spread the use of it.
