Evaluate the importance of various technologies, including Canadian contributions, to our understanding of internal body systems (digestive, circulatory or respiratory)
Technology. What is Technology? Technology is the usage and knowledge of tools, techniques, and, or is systems or methods of organization, or is a material product (such as clothing) of these things.Technology has evolved so much and can be found in almost everything. The use of technology has branched and expanded to help people in everyday life. From eating your breakfast in the morning, to brushing your teeth at night, technology helps our everyday routine easier. Technology has contributed to our everyday lives but the most important field that the technology does is medicine. Technology and Medicine have helped aid the sick people, find new cures, and so much more. Technology has also helped us find out about the different systems in our bodies, such as the circulatory, cardiovascular, digestive, respiratory, etc. All of this knowledge technology has given us has contributed so much to explore the human body and how it works.
The Endoscope
When surgery is needed your doctor may say that she'll be using an endoscope during your surgery. What is an endoscope? An endoscope is a small surgical video device used during procedures. The endoscope instrument is a lighted flexible instrument in which it contains a camera so a medical professional can use it to inspect interior organs. The first endoscope that was ever created was by Philip Bozzini in 1806 and was first introduced into a human in 1822 by William Beaumont, an army surgeon. It allows the surgeon to work with very small incisions by giving him visual access underneath the skin. During the procedure of using and endoscope, the doctor usually inserts the tube through an opening in the body, such as the mouth or the anus. In different situations the endoscope can also be inserted through a small incision. This endoscope procedure is to see inflammation or bleeding that don`t show up properly on x-rays. The main reasons to perform an endoscopy include symptoms such as bleeding, pain, or any change in bowel (Bowel: the canal between the mouth and anus) habits.
The Stethoscope
What is a stethoscope? It is an instrument for listening inside the body for external and diagnostic purposes. Stethoscopes are also often considered as a symbol of the doctor's profession. Before the Stethoscope was invented the patients were very limited to external observations. It was first invented by Rene Laeneec in France in 1816. Laennac developed a wooden stethoscope. As years pass the American doctor George P. Cammann developed the abinaural stethoscope in 1852 which then became the standard until 1940`s in which Rappaport and Sprague invented a new acoustic stethoscope which was two sided. The two sides were made to listen to the respiratory system or the cardiovascular system, each side only sends out high or low frequencies to the listener`s ears. The Rappaport-Sprague was later produced by Hewlett-Packard. HP's medical products then went to Agilent Technologies, where it became Agilent Healthcare. Agilent Healthcare was purchased by Philips which became Philips Medical Systems. Today here are still cardiologists who consider the original Rappaport-Sprague to be the best acoustic stethoscope. Today Rappaport-Sprague copies are now made in China currently sold for about $20.00US. The Rappaport-Sprague model stethoscope is heavy and short (18–24 in (46–61 cm)).
The Sphygmomanometer
What is a Sphygmomanometer? It is an instrument for measuring blood pressures, particularly in arteries. The Sphygmomanometer was invented by Samuel Siegfried Karl Ritter von Basch in 1881 and in 1896 Scipione Riva-Rocci invented a more easily used version. Later on, Harvey Cushing discovered this device in 1901 and popularized it. This instrument is consisted of an inflatable cuff, a measuring unit, and inflation bulb and valve. The inflatable cuff is to be put around your upper right arm and the inflation bulb is then to pump the cuff to restrict blood flow around the arm. Slowly, the doctor releases the air in the cuff to let the blood flow properly as he/she reads your blood pressure in the measuring unit. All of these machines have helped us cure millions of people and have been continuing doing so till this very day.
