Design of a Programmed Oxygen Delivery System

Abstract

This research aims to program a data base of prominent and the most

common diseases, which require supplementary oxygen care, by

determining the specific range between the maximum and minimum dose,

those can give a satisfied result. The minimum level will be given

automatically, to increase the oxygen level and to determine the patient

timing that will be subject to medical consultation and doctor's

recommendations.

The main objectives of this thesis are, over dose risk to be prevented,

medical mistakes to be avoided, hypoxemia to be relived andadequate

oxygenation of tissues to be maintained.

The methodology of the research is based on, designing the control circuit,

through which the oxygen dose can be controlled via a stepper motor with

valve, programming that is opened according to the signal coming from the

microcontroller, will be determined the stepper motor steps . The

microcontroller Atmage 32 is programmed by using the basic compiler

language (BASCOM) to control the stepper motor KP35FM2-027.

Through The observation The results are confined in 10 L/min is the

maximum output from the total open valve ,can be obtained by 39 steps

from the stepper motor , according to this result the mathematical segmentation is done, finally the outputs obtained are acceptable.
