Medical Technology
X-rays
– are a
form of electromagnetic radiation, just like visible light. In a health care
setting, a machines sends individual x-ray particles through the body. A
computer or special film is used to record the images that are created.
Stethoscope - an instrument used to detect and study
sounds produced in the body that are conveyed to the ears of the listener
through rubber tubing connected with a usually cup-shaped piece placed upon the
area to be examined.
magnetic resonance imaging (MRI)
- An
MRI (or magnetic resonance imaging) scan is a radiology technique that uses
magnetism, radio waves, and a computer to produce images of body structures. An
MRI scan can be used as an extremely accurate method of disease detection
throughout the body. In the head, trauma to the brain can be seen as bleeding
or swelling. Other abnormalities often found include brain
aneurysms, stroke,
tumors
of the brain, as well as tumors or inflammation of the spine.
angiosplasty
- is
a procedure used to open blocked or narrowed coronary (heart) arteries. The
procedure improves blood flow to the heart muscle.Atherosclerosis can affect
any artery in the body. When atherosclerosis affects the coronary arteries, the
condition is called coronary heart disease (CHD) or coronary artery disease.
electrocardiography
electrocardiography
- A
recording of the electrical activity of the heart. An electrocardiogram is a
simple, non-invasive procedure. Electrodes are placed on the skin of the chest
and connected in a specific order to a machine that, when turned on, measures
electrical activity all overaround the heart. Output is usually in the form of
a long scroll of paper displaying a printed graph of activity. Newer models
output the data directly to a computer and screen, although a print-out may
still be made.
To take a
specific situation, the initial diagnosis of a heart attack is usually made by
a combination of clinical symptoms and characteristic electrocardiogram
changes. The ECG can detect areas of muscle ischemia (muscle deprived of
oxygen) and/or dead tissue in the heart.
artificial pacemaker
- A device that uses electrical impulses
to regulate the heart rhythm or to reproduce that rhythm. An internal pacemaker
is one in which the electrodes into the heart, the electronic circuitry and the
power supply are implanted (internally) within the body.
bone marrow transplant
- A bone marrow transplant is a
procedure to replace damaged or destroyed bone marrow with healthy bone marrow
stem cells.
Bone
marrow is the soft, fatty tissue inside your bones. Stem cells are immature
cells in the bone marrow that give rise to all of your blood cells.
endoscopy
- a
doctor is able to see the inside lining of your digestive tract. This
examination is performed using an endoscope-a flexible fiberoptic tube with a
tiny TV camera at the end. The camera is connected to either an eyepiece for
direct viewing or a video screen that displays the images on a color TV. The endoscope
not only allows diagnosis of gastrointestinal (GI) disease but treatment as
well.
robotic surgery
robotic surgery
- Robotic
surgery, computer-assisted surgery, and robotically-assisted surgery are terms
for technological developments that use robotic systems to aid in surgical
procedures.
Robotically-assisted surgery was developed to overcome both the limitations of minimally invasive surgery or to enhance the capabilities of surgeons performing open surgery. In the case of robotically assisted minimally invasive surgery, instead of directly moving the instruments, the surgeon uses one of two methods to control the instruments ; either a direct telemanipulator or by computer control. A telemanipulator is a remote manipulator that allows the surgeon to perform the normal movements associated with the surgery whilst the robotic arms carry out those movements using end-effectors and manipulators to perform the actual surgery on the patient. In computer-controlled systems the surgeon uses a computer to control the robotic arms and its end-effectors, though these systems can also still use telemanipulators for their input. One advantage of using the computerised method is that the surgeon does not have to be present, indeed the surgeon could be anywhere in the world, leading to the possibility for remote surgery. In the case of enhanced open surgery, autonomous instruments (in familiar configurations) replace traditional steel tools, performing certain actions (such as rib spreading) with much smoother, feedback-controlled motions than could ever be achieved by a human hand

Cornea Transplant
- also known as corneal grafting, is a
surgical procedure where a damaged or diseased cornea is replaced by donated
corneal tissue (the graft) in its entirety or in part . The graft has been
removed from a recently deceased individual with no known diseases or other
factors that may affect the viability of the donated tissue or the health of
the recipient. The cornea is the transparent front part of the eye that covers
the iris, pupil and anterior chamber. The surgical procedure is performed by
ophthalmologists, medical doctors who specialize in eyes, and is often done on
an outpatient basis.
hemodialysis
- is a method for extracorporal removing
waste products such as creatinine and urea, as well as free water from the
blood when the kidneys are in renal failure. Hemodialysis is one of three renal
replacement therapies (the other two being renal transplant; peritoneal
dialysis). An alternate method for extracorporal separation of blood components
such as plasma or cells is apheresis.
Hemodialysis can be an outpatient or inpatient therapy. Routine hemodialysis is conducted in a dialysis outpatient facility, either a purpose built room in a hospital or a dedicated, stand alone clinic. Less frequently hemodialysis is done at home. Dialysis treatments in a clinic are initiated and managed by specialized staff made up of nurses and technicians; dialysis treatments at home can be self initiated and managed or done jointly with the assistance of a trained helper who is usually a family member

CT scan
- A
CT scan stands for Computed Tomography scan. It is also known as a CAT
(Computer Axial Tomography) scan. It is a medical imaging method that employs
tomography. Tomography is the process of generating a two-dimensional image of
a slice or section through a 3-dimensional object (a
tomogram). The medical device (the machine) is called a CTG scanner; it is a
large machine and uses X-rays. It used to be called an EMI scan, because it was
developed by the company EMI. Undergoing a CT scan is a painless
procedure.
ultrasound
- Ultrasound
imaging, also called ultrasound scanning or sonography, involves exposing part of the
body to high-frequency sound waves to produce pictures of the inside of the
body. Ultrasound examinations do not use ionizing radiation (as used in x-rays).
Because ultrasound images are captured in real-time, they can show the
structure and movement of the body's internal organs, as well as blood flowing
through blood vessels.
cardiac defibrillator
- is a
common treatment for life-threatening cardiac
arrhythmias, ventricular fibrillation and pulseless ventricular
tachycardia. Defibrillation consists of delivering a therapeutic dose of
electrical energy to the affected heart with a device called
a defibrillator. This depolarizes a critical mass of the heart muscle,
terminates the arrhythmia, and allows normal sinus rhythm to be
reestablished by the body'snatural pacemaker, in the sinoatrial
node of the heart. Defibrillators can be external, transvenous, or
implanted, depending on the type of device used or needed. Some external units,
known as automated external defibrillators, automate the diagnosis of
treatable rhythms, meaning that lay responders or bystanders are able to use
them successfully with little, or in some cases no training at all.
kidney transplant
kidney transplant
- is
the organ transplant of a kidney into a patient
with end-stage renal disease. Kidney transplantation is typically
classified as deceased-donor or living-donor transplantation depending on the
source of the donor organ. Living-donor renal transplants are further
characterized as genetically related (living-related) or non-related
(living-unrelated) transplants, depending on whether a biological relationship
exists between the donor and recipient.
Incubator
- An apparatus in which environmental conditions, such as
temperature and humidity, can be controlled, often used for growing bacterial
cultures, hatching eggs artificially, or providing suitable conditions for a
chemical or biological reaction. An apparatus for maintaining an infant,
especially one that is ill or born before the usual gestation period, in an
environment of controlled temperature, humidity, and oxygen concentration.
Nebulizer
-
In medicine, a nebulizer is a device used to administer medication in
the form of a mist inhaled into the lungs.
A Jet nebulizer is attached to a compressor.
Nebulizers are commonly used for treatment of cystic fibrosis, asthma, COPD and other respiratory diseases

Respirator
- a respirator is a device designed to
protect the wearer from inhaling harmful dusts, fumes, vapors, or gases.
Respirators come in a wide range of types and sizes used by the military,
private industry, and the public. Respirators range from cheaper, single-use,
disposable masks to reusable models with replaceable cartridges.
Heart Transplant
- a
heart transplant, or a cardiac transplantation, is a surgical transplant
procedure performed on patients with end-stage heart failure or severe coronary
artery disease. As of 2007 the most common procedure was to take a working
heart from a recently deceased organ donor and implant it into the patient. The patient's
own heart is either removed or, less commonly, left in place to support the
donor heart, both were controversial solutions to an enduring human ailment.
Post-operation survival periods averaged 15 years.
Skin Grafting
- Among the indications for skin grafting are promotion
of accelerated healing of burns and other wounds, reduction of scar
contracture, enhancement of cosmesis, reduction of insensible fluid loss, and
protection from bacterial invasion.
