Blood gas analyzer

The best application of electronics in the medical field is gas analyzer. It is used to calculate the pressure of the chemical elements like carbon monoxide, nitrogen, oxygen in blood. By analyzing results we able to understand if any disorder in blood, particularly after we feel sick quite 2days. By exploiting results we are able to observe if any disorder when we feel sickness within the basic level solely within the home. It is often enforced as medical electronics projects.

Blood Gas analyzer

Blood collected from the person is introduced within the chemical device strip that has particle selective electrodes, by exploitation by device amplifiers and analog electronic device, the results are going to be shown in a digital manner with ADC for a microcontroller. Then the output is going to be displayed within the digital display module in terms of millimeters of mercury (mmHg), kilopascals (kPa), typical values for the carbon monoxide and dioxide measure thirty four(34) to thirty five (35) mm Hg , which of Oxygen in between eighty(80) to ninety (90) mm Hg.

Blood Glucose Monitor

Blood glucose monitor is used to calculate glucose level of diabetic patients. These devices are often designed as medical electronic projects. The working of blood glucose monitor is, when a little drop of blood is placed on the chemical strip, the strip has sensors to live content of various chemical components, within seconds it will calculate the amount of glucose in the blood and displays by using a LED display.

Blood Glucose Monitor

It is very helpful to observe sugar levels with less prices and straight forward approach. It is a relief to a heap of diabetic patients. Making of Blood Glucose Monitor is easy by usual material which are available in the market.

Brain Wave Machine

Brain wave machine is one type of instrument in medical electronics which is used to  record the electrical activity of the scalp with Electroencephalography by firing of neurons within the brain. It processes the data that has taken from the electrodes which are placed on the scalp and can be displayed within the screen. It is helpful in the treatment of disorders of brains like sleeping disorder, brain death, and mental unhealthiness, also in emergency units at hospitals. These types of electronic devices are used in the medical field in the treatment of mental issues.

Brain Wave Machine

Electronic Cardiac Monitor

The Electronic Cardiac Monitor  is used in all medical electronics applications. This medical electronic device is used to display the electrical and pressure waveforms of the cardiac system. By inserting specific electrodes on the various elements of the body we can get ECG of the cardiac system. It will observe irregular activity within the cardiac system and heart issues. It is used throughout medical treatment and especially while surgery.

Electronic Cardiac Monitor

Digital Thermometers

The digital thermometers are used to sense the temperature of the body and these devices are portable, have permanent probes, and a convenient digital display. These devices are used in different industries to control processes in scientific research, the study of weather and in medicine.

Digital Thermometers

IR Thermometers

IR thermometer is used to measure the temperature by detective work with radiation generated by the body. These devices are often used in airports for defectively knowing the condition of passenger’s health from a distance to observe the diseases like viral hemorrhagic fever like EBOLA, SAARC etc. This system consists of a lens to focus the infrared (IR) energy onto a target body, and detects the energy, and displayed in the form of electrical signal which will be displayed in units of temperature.

IR Thermometer

Defibrillator

Defibrillator is used in emergency conditions like heart attack occurs. It affects the rhythm of the heart such as ventricular fibrillation, cardiac arrhythmia and pulseless ventricular tachycardia. The working procedure of the Defibrillator involves, when the electric shock delivers to the heart, it causes depolarization of the muscles of the heart and regenerates normal conduction of the electrical pulse of the heat. There are different types of defibrillators include implanted, trans venous and external defibrillators

Defibrillator

Sphygmomanometer

 The sphygmomanometer is a device used to measure blood pressure(BP), composed of an inflatable cuff to control blood flow and a mercury to measure the pressure.The standard unit of measurement of BP is millimeters of mercury (mmHg) as directly measured with  a manual sphygmomanometer. These devices are classified into two types they are Mercury Sphygmomanometers and Aneroid Sphygmomanometers.

Sphygmomanometer

MRI (Magnetic Resonance Imaging)

The medical resonance imaging technique is used in radiology, to review the natural object of inner elements of the body. They use strong magnetic fields to make pictures of the body. Magnetic resonance imaging includes a big selection of applications in diagnosing and there calculable to be over scanners in use worldwide. Magnetic resonance imaging has an effect on identification and treatment in several specialties, though the effect on improved health outcomes is unsure.

Magnetic Resonance Imaging

Since magnetic resonance imaging doesn’t use any radiation its use is usually recommended in preference to CT once either modality might yield a similar information. Image resonance is normally a security technique, however the amount of incidents inflicting patient damage has up. Contraindications to magnetic resonance imaging body most tube-shaped structure implants and cardiac pacemakers, shell gold and foreign bodies within the orbits. The protection of magnetic resonance imaging throughout the primary trimester of physiological condition is unsure; however, it’s going to be desirable to different choices. The sustained increase in demand for magnetic resonance imaging among the attention trade has died to considerations concerning price effectiveness and other medical specialty.

Stethoscope

The stethoscope is an audio medical device for listening to the internal sounds of the human body or an animal. It is frequently used to hear the sounds of the lung and heart. It is also used to listen to intestines and blood flow in veins and arteries. It is used In combination with a sphygmomanometer for measurements of blood pressure. Stethoscopes can also be used to check scientific vacuum chambers for leaks, and for various other small-scale acoustic monitoring tasks.

Stethoscope

Therefore, this is all about Medical Electronics Applications in Engineering which includes MRI, Stethoscope,Sphygmomanometer, Defibrillator,IR thermometers, Digital thermometers, Electronic cardiac monitor, Brain wave machine, Blood glucose monitor.
