12 LEAD ECG TRAINER-BIOMEDICAL PROJECTS

Computer Engineering electronics Engineering Civil Engineering

Electrocardiograms (ECG) are used to measure the electrical activity of the heart and diagnose arrhythmia. Currently there is no training mannequin that teaches both 12-lead electrode placement and ECG signal interpretation in one device. The purpose of this project is to develop an adult mannequin that teaches placement of electrodes based on anatomical landmarks and provides the student with feedback about the accuracy of their placement. The same mannequin should also produce a variety of ECG output signals to teach diagnostics using 12

16 CHANNEL BRAIN TISSUE STIMULATOR

The pathways of brain circuitry can be studied by delivering current impulses to brain tissue and observing the tissue response. The goal of this project is to develop a current source to be used for in vitro stimulation of rodent neural tissue. The current source must deliver independently controlled currents to 16 separate electrodes on a 16 microelectrode array. In addition, the currents must be controllable via TTL computer logic and have a short response time to the initial signal. The design described in this report uses a transformer to supply a large isolated voltage to 16 circuits which will convert the voltage to an appropriate current. The current on each channel will be controlled by a potentiometer which varies the magnitude of the impulse received from a TTL computer signal. When the computer program supplies an impulse, a corresponding square wave current pulse will be applied to the tissue.

BIO-TECH PROJECT ON NANOTECHNOLOGICAL PROPOSAL OF ARTIFICIAL RBC

Molecular manufacturing promises precise control of matter at the atomic and molecular level, allowing the construction of micron-scale machines comprised of nanometer-scale components. Medical nanomachines will be among the earliest applications. The artificial red blood cell or "respirocyte" proposed here is a bloodborne spherical 1-micron diamondoid 1000-atm pressure vessel with active pumping able to deliver 236 times more oxygen to the tissues per unit volume than natural red cells and to manage carbonic acidity. An onboard nanocomputer and numerous chemical and pressure sensors enable complex device behaviors remotely reprogrammable by the physician via externally applied acoustic signals.

BIO-TECH PROJECT ON TREATMENT OF BRAIN TUMOR USING NANOROBOTS

The nanotechnology provides the sophisticated way to eliminate the brain tumor completely by using the nanorobots without any side effects. These nanorobots are programmed in order to perform the operation efficiently. These nanorobots are injected into the body of the patient. The moment they get injected, they form a reference point of that spot and are allowed to navigate through the blood vessels. The sensors inside the nanorobots are used to locate the tumor areas in the brain. The tumor cells are scooped by the nanorobots and return to the spot, where it actually enters the body of the patient. Receiving the signal that is produced by the nanorobots while they navigate inside the blood vessels could also sense the position of the nanorobots. This technique could be implemented in future, which assures for a complete remedy from the brain tumors.

BIOMECHANICS OF THE INTERVERTEBRAL DISC- THE EFFECTS OF LOAD HISTORY ON MECHANICAL BEHAVIOR

Degenerative disc disease is associated with back pain, and can be a debilitating disorder. In addition to the biological contributions of genetics and aging, mechanical factors have been implicated in accelerating the progression of disc degeneration. Two studies were performed in order to explore the effects of various loading conditions on disc biomechanics. The first study explores the effects of compressive historical loads and disc hydration on subsequent creep loading and recovery. The second study investigates the restorative powers of creep distraction between compressive loading periods. In both cases three commonly applied mathematical models were employed to characterize disc behavior and the effectiveness of each model was validated. The studies confirm that hydration level has a significant impact on disc stiffness and time dependent behavior. Distraction and conditioning phases are shown to have a significant impact on hydration level and thus subsequent mechanical behavior. Introduction- The Intervertebral Disc- The intervertebral disc (IVD) is found between two subsequent vertebral bodies allowing the spine to flex and twist while supporting gravitational and muscular loads. A motion segment is comprised of an intervertebral disc and its two neighboring vertebral bodies. The mechanical properties of the disc are imperative to its normal operation. The disc is comprised of several components that each contribute to the mechanical properties. Degradation of these components can lead to reduced mechanical performance as well as pain. The disc degenerates naturally as a normal part of aging, but the relationship between degeneration and pain is not fully understood. Studies are focused on differentiating between natural aging and the debilitating effects of more extreme degeneration. The effects of degeneration on the mechanical behavior of the disc may be a contributing factor to pain. Degeneration can lead to degraded biomechanics in terms of increase

FINGER PLETHSYMOGRAPH TO MEASURE BLOOD RESISTIVITY

Impedance plethysmography can be used to measure arterial volume change that occurs with propagation of the blood pressure pulse in a limb segment. For this measurement, we assume a constant value of blood resistivity. However, blood resistivity may change under both physiological and pathological conditions. Use of an impedance plethysmograph on a finger immersed in a saline filled beaker may yield a method for determining this change in blood resistivity. This may develop into a method that diabetics can use to measure glucose levels non-invasively. The goal of our project is to design a finger plethysmograph to measure blood resistivity.

GUIDANCE OF WHEEL CHAIR USING ELECTROOCCULOGRAPHY

This involves a new method to control and guide mobile robots. In this case, to send different commands is used electrooculography techniques (EOG), so that, control is made by means of the ocular position(eye displacement into its orbit). This control technic can be useful in multiple applications, but in this work isused to guide a autonomous robot (wheelchair) as system to help to people with severe disabilities. The systemconsists of a standard electric wheelchair with an on board computer, sensors and graphical user interface running on a computer.

IMPROVED VERSION OF MUSCULAR BIO STIMULATOR

T1 is a small mains transformer 230 to 12V @ 100 or 150mA. It must be reverse connected, i.e. the 12V secondary winding across Q3 Collector and negative ground, and the 230V primary winding to P3 and output Electrodes. The circuit has been thoroughly tested, and it works nicely when supplied in the 3V - 9V range. Running on 3V supply with a 12V 1.2VA transformer it would be no more dangerous than the circuit already published. But please note that using 9V battery supply it can output 120V signals and could be very dangerous. Electrodes can be obtained by small metal plates connected to the output of the circuit via usual electric wire and can be taped to the skin. In some cases, moistening them with little water has proven useful. Commercial sets have frequently a built-in 30 minutes timer. For this purpose we can use the Timed Beeper the Bedside Lamp Timer or the Jogging Timer circuits, adjusting the timing components to suit your needs.

INFRARED HEART PULSE MONITOR

The invention herein described is intended to provide the user with a reliable heart rate monitor that is a completely self contained unit and is capable of providing accurate readings while the wearer is moving about. The use of piezoelectric sensing elements eliminates the power drain caused by LEDs and similar devices. The sensing element mounting means disclosed herein is devised to greatly reduce the noise introduced into the pulse signal by body motion. The use of optical sensors in a staring mode and optical sensors in a pulsed mode is also presented. The effects of noise are further reduced by employing digital signal processing algorithms to find the heart pulse intermixed with noise signals and present the heart pulse rate in beats per minute on a display. The resulting device permits the visual monitoring of the heart pulse rate in a human body in a consistent, error-free manner.

LOW COST ECG MACHINE DESIGN USING 8-BIT MICROCONTROLLER

Electrocardiogram (ECG) is considered to be the backbone of cardiology. In this we have explored a suitable way of designing an ECG machine using 8-bit microcontroller and certain discrete components. Proposed system consists of AD624 as instrumentation amplifier to amplify the bio potential received from body using electrodes. This signal is then passed through analog filters to filter out unwanted signal like baseline wander, power line noises etc. Microcontroller is used to process data digitally to send towards LCD screen to display or data logging unit to provide storage of ECG for future usage. Finally we explored a way to transfer data over GSM Model to the physician.

MAKE YOUR OWN EEG DEVICE

An EEG signal is usually acquired through silver-chloride covered electrodes, though sometimes other materials like pure silver, tin, steel or gold are used. The signal amplitude is only a few microvolt and needs to be amplified several thousand times before it can be captured. Because it is faint, the signal can very easily drown in noise, particularily 50/60Hz hum from the mains which is transmitted capacitively (i.e by an electric field) from the wiring in your house. To handle this, the signal is first amplified by a high quality instrumentation amplifier, which measures the voltage difference between two locations on the scalp. In the example in the previous section, we used C3 and P3. This ensures that a large percentage of the mains hum never enters the system, because the level of the mains hum on those two locations is essentially the same. Afterwards the signal strength is increased further by normal amplifiers, and passed through a low-pass filter which minimizes distortion caused by so-called aliasing that may occur when the signal is converted to digital samples.
