Medical Auto-Injector Design

Abstract:

A kind simple structure and convenient operation of automatic injector is designed in the paper. It can be placed on the desk with the friendly interface. Its core components are AT89C51 and stepping motor. SCM can be controlled by the corresponding key to send the logic control signal through software programming. In order to achieve the automatic injection function under different speeds at 20 ml, 30 ml and 50 ml liquid level, automatic injector is drove by the different statuses of stepping motor, such as open and stop, acceleration and deceleration, turning and reversal, etc. For driving stepping motor more better, the drive chip ULN2003 is used. The speed, the turning direction and the injection dose of stepping motor is displayed with LED. It realizes the well-proportioned injection, avoids the error caused by artificial operation and uncertainty, and reduces the pressure of the medical staff.
