Abstract
In today's era when precise, accurate and timeefficient systems are in great demand, automated techniquessupersede manual practices. As a need of time, we introduce awireless, automated, cost effective, yet reliable and efficientsystem of fluid dispensing. Our prototype system can dispensevarying amounts of fluids in milliliters (maximum 1L) as perdemand of the user. It uses the principle of time based fluiddispensing achieved through the built-in timer property of theAT89C51 microcontroller. To satisfy the principle used andverify the system's accuracy, fluids of varying viscosities weredispensed and monitored. The experimental results of thewireless fluid dispensing system when tested showed linearrelationship between the dispensing time and desired volumes offluids having differing viscosities. The added feature of wirelesscontrol using HM-TRP series transceiver module along with onsitecontrol via a keypad eliminated the need of physical presenceof operator within the range of 10 meters in order to make thesystem operational. This system can be used in pharmaceuticaland beverage industries as well as in different laboratories fordispensing and filling volumes of fluids with varying viscosities.
Highlights
A normal heart beats 60 to100 times per minute in order to pump blood to the body but this pumping action requires electrical conduction
To treat ventricular fibrillation a therapeutic device defibrillator is used to deliver high electric voltages to the heart which causes depolarization of abnormal contraction of the heart muscles and against obelized normal conduction of the heart’s electrical impulse and normal activity of heart can be restored with proper delivery of shocks
Doctors use different types of defibrillators, which include external defibrillators and implanted defibrillators. These defibrillators sometimes failed to restore the cardiac functions due to the charging and discharging failure or by inadequate device operation by paramedical staff. It has been confirmed from previous researches that early defibrillation is very important because immediate defibrillation can result in increasing the survival rates of more than 90%, as cardiac arrest leads to a 10% reduction in survival each minute, so early treatment of patient is very vital [4]
Summary
A normal heart beats 60 to100 times per minute in order to pump blood to the body but this pumping action requires electrical conduction. An automated external defibrillator requires minimal training to use It automatically diagnoses the heart rhythm via ECG machine and determines if a shock is needed via LabVIEW, it is highly feasible for patient who requires urgent care in case of a sudden cardiac arrest and the unavailability of a physician at that time. Another main advantage is that, this system is cost efficient. Electric shock is discharged across the chest by pushing the button when action is desired so that patient is provided with proper dosage of electric shock within instant duration
