circuit diagram microcontroller based anesthesia injector
: In the hospitals, any major operation is performed; the patient must be in anesthetizing condition. If the operation lasts for a long time, say for suppose for 4 or 5 hours, anesthesia cannot be give in a single stroke to the patient. Over dosage may cause a critical condition for the patient s towards death. If lower amount of anesthesia is to the patient, they may wakeup at the middle of the operation. Overcome this problem, the anesthetist administers few millilitres of anesthesia per hour to the patient in a particular time period. If the anesthetist fails to administer the anesthesia to the patient at the particular time interval. Overcome this problems the design of an automatic operation of an anesthesia machine based on a microprocessor is effective. In this system a keypad is provided along with the Microprocessor and syringe infusion pump. The anesthetist can set the level of anesthesia in terms of millilitres per hour to administer anesthesia to the patient with the help of keypad. when signal is received. After receiving the signal from the keypad, the Microprocessor controls the signal to the desire level and fed into the stepper motor to drive the infusion pump in proper manner. The anesthesia is administered to the patient according to the stepper motor rotation .if any uncertain condition the alarm will on.Automatic anesthesia injector (AAI), is an virtual reality system creating new dimensions the field of medical sciences, in our project we implemented an micro controller based automatic anesthesia injector system, operates under the supervision of the 8051 micro controller .
which acts as an processing unit for the entire system, in this computer simulated environment everything is controlled by the artificial devices without any manual operations.
In order to control pain and stress for the patient undergoing surgery anesthesia plays a vital role. In recent times due rapid advancement of embedded systems in real time computing, having ability to control many devices at a time, these embebdded systems paved path to the invention of micro controller, this micro controller is a real time operating system can read data and can perform various calculations based on the varying conditions, it consists of memory device in which the entire program is stored to perform various tasks, this integrated single chip consists every parts of an controller on it, this painkilling anesthesia is to be properly injected in to the patient s body based upon the requirement any variations in the content of dose may leads to emergency condition.
