  1. 1. Biomedical Equipments Compiled by: Prof.G.B.Rathod EC Department, BVM Email: ghansyam.rathod@bvmengineering.ac.in
  2. 2. ECG Machine and Its lead connections • This test is usually done by a trained technicians. • Small metal disks (electrodes) which have wires that hook to an electrocardiograph machine are placed on the chest as you lie on the exam table. • A lubricating gel is applied on the chest to help sound waves pass through the skin. The lubricating gel may feel cold. Selected sites are shaved, if necessary. • During the test, you may be asked to remain motionless or hold your breath at times. • The electrical activity is recorded as waves on a graph, with different patterns corresponding to each electrical phase of the heartbeat. • Lets see how to perform ECG test using vesta 300i Prof.G.B.Rathod, EC Dept.BVM-EC453 2

  4. 4. EMG Test 4 Prof.G.B.Rathod, EC Dept.BVM-EC453
  5. 5. EMG Test • Electromyography (EMG) is a diagnostic procedure that evaluates the health condition of muscles and the nerve cells that control them. These nerve cells are known as motor neurons. They transmit electrical signals that cause muscles to contract and relax. An EMG translates these signals into graphs or numbers, helping doctors to make a diagnosis. • A doctor will usually order an EMG when someone is showing symptoms of a muscle or nerve disorder. These symptoms may include tingling, numbness, or unexplained weakness in the limbs. EMG results can help the doctor diagnose muscle disorders, nerve disorders, and disorders affecting the connection between nerves and muscles. • Lets see how to perform EMG test. 5 Prof.G.B.Rathod, EC Dept.BVM-EC453
  6. 6. Brain and Brain Waves • The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. • Lets see the parts and functions of the human brain Prof.G.B.Rathod, EC Dept.BVM-EC453 6
  7. 7. Brain and Brain Waves • Neurons are the building blocks of the nervous system. They receive and transmit signals to different parts of the body. This is carried out in both physical and electrical forms. There are several different types of neurons that facilitate the transmission of information. • Lets see basic working or neurons Prof.G.B.Rathod, EC Dept.BVM-EC453 7
  8. 8. EEG • An electroencephalogram (EEG) is a test used to evaluate the electrical activity in the brain. Brain cells communicate with each other through electrical impulses. An EEG can be used to help detect potential problems associated with this activity. • Lets understand the basic of EEG measurement. Click here Prof.G.B.Rathod, EC Dept.BVM-EC453 8
  9. 9. Pace Makers • A pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses low-energy electrical pulses to prompt the heart to beat at a normal rate. Pacemakers are used to treat arrhythmias. Arrhythmias are problems with the rate or rhythm of the heartbeat. Prof.G.B.Rathod, EC Dept.BVM-EC453 9
  10. 10. Block diagram of Early R-wave Synchronous Pacemaker Prof.G.B.Rathod, EC Dept.BVM-EC453 10 Click here to see the How pacemaker works.
  11. 11. Defibrillator • Fibrillation is the rapid, irregular, and unsynchronized contraction of muscle fibers. An important occurrence is with regard to the heart. • Defibrillators are devices that restore a normal heartbeat by sending an electric pulse or shock to the heart. They are used to prevent or correct an arrhythmia, a heartbeat that is uneven or that is too slow or too fast. Defibrillators can also restore the heart's beating if the heart suddenly stops. Prof.G.B.Rathod, EC Dept.BVM-EC453 11 Automated External Defibrillator
  12. 12. Defibrillator Block Diagram Prof.G.B.Rathod, EC Dept.BVM-EC453 12
  13. 13. Procedure to use Defibrillator • Step 1: Turn the defibrillator on by pressing the green button and follow its instructions. • Step 2: Peel off the sticky pads and attach them to the patient's skin, one on each side of the chest, as shown in the picture on the defibrillator. • Step 3: Once the pads have been attached, stop CPR and don't touch the patient. • Step 4: The defibrillator will assess whether a shock is needed and if so, it will tell you to press the shock button. An automatic defibrillator will shock the patient without prompt. Do not touch the patient while they are being shocked. • Step 5: The defibrillator will tell you when the shock has been delivered and whether you need to continue CPR. • Step 6: Continue with chest compressions and rescue breaths until the patient shows signs of life or the defibrillator tells you to stop so it can analyse the heartbeat again. • Lets see the CPR and use of Defibrillator.

  14. 14. Laser in Surgery(LASIK) • LASIK or Lasik (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia,hyperopia, and astigmatism. LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most people, LASIK provides a long-lasting alternative to eyeglasses or contact lenses. • Lets see How the Laser is useful in surgery Prof.G.B.Rathod, EC Dept.BVM-EC453 14

  17. 17. Robotic Surgery 17 Prof.G.B.Rathod, EC Dept.BVM-EC453 Robotic or Robot-assisted surgery integrates advanced computer technology with the experience of the skilled surgeons. This technology provides the surgeon with a 10x magnified, high- definition, 3D-image of the body's intricate anatomy.
  18. 18. Robotic Surgical Procedure • The surgeon uses controls in the console to manipulate special surgical instruments that are smaller, as well as more flexible and manoeuvrable than the human hand. The robot replicates the surgeon's hand movements, while minimizing hand tremors. The surgeon thus can operate with enhanced precision, dexterity and control even during the most complex procedures. • Lets see the robots in medical domain. Prof.G.B.Rathod, EC Dept.BVM-EC453 18
  19. 19. Intensive Care Unit(ICU) Equipments • An intensive care unit (ICU), also known as an intensive therapy unit or intensive treatment unit (ITU) or critical care unit (CCU), is a special department of a hospital or health care facility that provides intensive care medicine. • Intensive care units cater to patients with severe or life- threatening illnesses and injuries, which require constant care, close supervision from life support equipment and medication in order to ensure normal bodily functions. Prof.G.B.Rathod, EC Dept.BVM-EC453 19

  21. 21. Biotelemetry System • Biotelemetry is the use of telemetry methods in order to remotely observe, document, and measure certain physiological functions in human beings or other living organisms. • The field consists of several subfields, including medical and human research telemetry, animal telemetry, and implantable biotelemetry. • Medical telemetry is of particular note because it can be used to remotely track the vital signs of ambulatory patients. • Generally, a biotelemetry system used for this purpose measures functions like body temperature, heart rate, blood pressure, and muscle movement. Prof.G.B.Rathod, EC Dept.BVM-EC453 21
  22. 22. Biotelemetry system • A biotelemetry system consists of transmitter and receiver. The biotelemetry transmitter and receiver block diagram are shown here. Physiological (EEG, ECG, EMG, etc.) signals are obtained by a suitable transducer which is amplified and subjected to modulate the carrier waves for transmission. Prof.G.B.Rathod, EC Dept.BVM-EC453 22
  23. 23. Plasma Medicine • Plasma medicine is an emerging field that combines plasma physics, life sciences and clinical medicine. • It is being studied in disinfection, healing, and cancer. Most of the research is in vitro and in animal models. It uses ionized gas (physical plasma) for medical uses or dental applications. • Plasma, often called the fourth state of matter, is an ionized gas containing positive ions and negative ions or electrons, but is approximately charge neutral on the whole. • The plasma sources used for plasma medicine are generally low temperature plasmas, and they generate ions, chemically reactive atoms and molecules, and UV-photons. • These plasma-generated active species are useful for several bio-medical applications such as sterilization of implants and surgical instruments as well as modifying biomaterial surface properties. • Sensitive applications of plasma, like subjecting human body or internal organs to plasma treatment for medical purposes, are also possible. • This possibility is being heavily investigated by research groups worldwide under the highly- interdisciplinary research field called 'plasma medicine Prof.G.B.Rathod, EC Dept.BVM-EC453 23
