Abstract
With modern medical science and the rapid development of continuously updated medical supplies, disposable infusion set has been extensive clinical application, thus the safety of their products and the passing rate on the more important. Disposable Infusion Set for qualified, there are two major problems: First, turn-on, there is a leak it is not. At present, the leak detection devices in the home infusion industry widely used method of manual inspection, to have by the end of this process, this method regardless of the passing rate of the product or production efficiency can not reach the current market demand; and international Although there are advanced production lines ready to manage water but because of its goods, price, technology, under conditions of secrecy, etc. applies to domestic manufacturers and some unrealistic. In this context the development of a new leak detection system of the infusion set would be a good prospect.
This paper describes the infusion set of the control system leak detection system software, and some of the hardware design process. The device should have the following main features: (1) Subject to the use of artificial feeding, the testing process to achieve automation; (2) detection of the process of products with automatic sorting function failure; (3) high reliability, can be a 24-hour continuous rather than a fault detection; (4) has a small footprint, simple structure and so on. According to the functional requirements, the author of this article a lot of inspection and analysis of comparative literature at home and abroad the advantages and disadvantages of the current detection method based on the identified control system design and software design. The control system of detection system to PLC and single-chip microcomputer-based programming.
This paper is divided into five chapters. The first chapter is the Introduction, the main leak introduced the infusion set and an analysis of the status quo at home and abroad for such type of equipment, the development trend of the demand, made clear the contents of the graduation project in the context of engineering applications.
The main contents of Chapter II of detecting device system call for a detailed analysis, including detection, sorting unqualified products (and plugging the leaks), the positioning of sensors. Shape and structure of proposed programs and program control systems, and this analysis.
Chapter III introduced the detector control system hardware components, including main control part at the core of the motor and sensor, and shows the links between them. In addition, a part of hardware, such as, location, design and selection of sensors.
Chapter IV is the next focus of this thesis, the chapter on the infusion set detection system software of the control system design, including PLC and single-chip design their own control procedures. The main subroutines are: initialization procedures, waste detection procedures, measurement procedures for blocking, sorting procedures failed products. During the design process, as well as the problems encountered and take the detour, as well as methods to resolve. The author of the software in the past come into contact with the design of small, so in the course of the preparation of procedures encountered many difficulties, through to find relevant information and guidance to help teachers has been resolved, the section corresponding to the description of some of the problems.
The final chapter is the concluding remarks on the subject of this graduation project and the completion of the main harvest are summarized.
