IEEE PROJECT BIOMEDICAL APPLICATION-Automatic Anesthesia
Controller using Heart Beat Sensor
At the present time anesthetics, drugs which induce loss of
awareness, are often used for surgical operations. A general anesthetic should
cause a progressive depression of the central nervous system and cause the
patient to lose consciousness. In contrast, a local anesthetic will affect
sensation at the region to which it is applied.
To maintain an adequate depth of anesthesia without
compromising patient's health, an anesthesiologist usually works as a
multi-task feedback controller to roughly regulate the drugs titration while
observing a variety of patient outcomes. Automatic anesthesia controller design
aims to automatically regulate anesthesia levels by taking account on several
physiological measurements and then frees up anesthesiologists for more
important tasks in operation.
This project designed using the PIC Microcontroller aids in the control
of feeding Anesthesia for patients during Surgery times. This project Consists of a Heart Beat
sensor to detect the Heart beat rate and
a Mechanical Arrangement with syringe for feeding anesthesia to the patients.
Operation:
First the
Syringe is filled with anesthesia liquid and kept in the mechanical
arrangement. And the Heart beat rate is
calculated. Then the Liquid is slowly
injected into patients body and the changes in the Heartbeat rate is observed.
Then according to the Heart beat rate the Liquid is injected into the
body.
The injecting process is controlled by the movement of the
Stepper Motor.
The Complete Status is Indicated in LCD with online Updations.
