20.2 Different Machinery in the Medical Field
Key Takeaway
Many different machines have been invented and have influenced the medical field in recent years. One major invention was the X-Ray which is the machine that takes pictures of the bones in your body, which tells the doctors if there is a fracture or break of certain bones. This machine can be used in small injuries such as a hairline fracture in a finger to major injuries such as a broken femur bone. Before x-ray imaging was invented, doctors had to use physical examination and straight-up guess if the bone was broken with the naked eye. These machines have taken the stress off all the doctors and made it easier to examine bones.

A computed tomography scan (CT scan) is a diagnostic tool that is used to detect certain diseases and injuries. These are mainly used when a doctor is looking for certain diseases such as cancer, heart disease, and many different medical conditions. They are also used for complex fractures and different joint problems. People tend to mistake CT scans for Magnetic Resonance Imaging (MRI Scan), but an MRI scan is a type of machine that uses a massive magnet and radio waves in order to look at different organs and structures inside the body. This type of machinery is typically used on someone who needs examining on their brain or their spinal cord. MRI scans are also used widely in sports because players will tend to get an MRI if they believe they have a torn ligament such as an ACL or MCL. The main difference between the CT scan and MRI scan is that CT scans use x-ray imaging from different angles of your body to get results while the MRI scan uses magnetic and radio waves to get results.
Electrocardiograms (ECG) are also used often in hospitals. These machines are used to evaluate someone’s heart rhythm and also the heart’s electrical activity. Different sensors that are attached to the ECG monitor are placed on the patient’s skin that reads the heartbeat of the patient and detects the electrical signals produced by the heart. The heartbeat is then shown on a graph connected to a machine so that the doctors can evaluate the heartbeat and signal that the heart is giving off. This is one of the easiest machines to work and read for a doctor.

20.3 History of Medical Devices
Key Takeaway
The 19th century is seen to be one of the greatest advancements in medical technology. One of the most major advancements in this century was the invention of the stethoscope. This tool is used to listen to the heartbeat of a patient and even to listen to lungs. Prior to this innovation, Doctors mostly had to rely on the stories that the patients told and the visual inspection of the patient’s body. Now, doctors can listen to the heart, this gives them more information about what could possibly be a certain condition the patient is dealing with. It ultimately reduced the significance of the patient’s story and the doctors learned to rely on what they could hear themselves through stethoscopes. Another massive invention in the 19th century was the clinical thermometer. This made it possible for doctors to get the temperature which would help them determine what sickness they possibly had.
Mechanical robots were invented in the late 1980s but were not actually introduced into the medical field until the 1990s. These certain robots were invented to be used in certain surgeries and also used for different things such as brain biopsies. These robots have been proven to be very helpful in certain surgeries and situations in the medical field. Laparoscopic surgery is a surgery that robotic devices have been used in all the time. There is a robotic arm that is synced up with a monitor that the doctor controls and the small arm goes through a small incision on the patient in order to get a view of the body. The doctor then controls the arm to make the certain cuts needed. These are mainly used when it is simple to make too big of a cut so they use small robotic arms in order to be safe and not risk the life of the patient.
Different robots have been invented recently to monitor certain patients that may have infections or different illnesses. The robots use non-contact methods such as using infrared light in order to read the patient’s body temperature. The robot is also able to take pictures of the patients so that the doctors can read the images of them and determine what is wrong. The robots are present to people who are in quarantine because they do not want to spread the virus or whatever illness they have and if the patient is in need of an urgent request, the robot can call the doctor and the patient can speak directly to the doctor.

20.4 Impact of Medical Devices on Society
Key Takeaway
Society has been greatly impacted as a whole by the different inventions of new medical technology. The new inventions have given doctors more clarity and made them more confident in what they diagnose. These machines have also given the evidence that they can prove to the patients instead of them having to go off a gut feeling and the naked eye, they have proof with pictures. The inventions have also made it so that there are better treatment options in hospitals and urgent care. This can be from the new inventions of a drug that can treat certain illnesses and better living conditions in the hospitals. The inventions have also given doctors the ability to research certain diseases and illnesses so that one day they can maybe form a cure for diseases like cancer or Alzheimers.
Society has also been greatly impacted by the advancements in technology because these inventions have saved many lives. This ultimately has increased the life expectancy for many people because if we did not have the machines used to find certain illnesses, doctors would never know how to treat someone. The increase in life expectancy has also made it so that certain people with jobs can work those jobs for a longer period of time. This all impacts the economy greatly. Inventions of new drugs through research has also been shown to be of great use because people have been cured of many diseases. This makes it so that they can live out their lives without the worry of suddenly passing which takes off the stress of many individuals.

20.5 Future of Medical Technology
Key Takeaway
The future of medical technology is bright, but there can be some things to keep an eye on. Some medical jobs may be taken in the near future by certain machines taking over the medical realm.
The future of medical technology is amazing for society and also for hospitals. Different advancements have come into the picture recently and one of those is the use of virtual reality in the medical field. Virtual reality is used widely in medical school for students to learn the anatomy of the body and to also learn about certain diseases up close. It is also used for treating certain patients in physical therapy. Another medical advancement that is looking bright in the future is prosthetic limbs. These devices are always being improved and improvised so that it fits the patient perfectly. Research is continuously being conducted to improve these devices. 3D printing has also taken a step into the medical field and improved some of the little things. Certain drugs have been improved to be 3D printed and this makes the pill dissolve faster in the body ultimately putting the drug to work faster. Some companies are also 3D printing some pills in different shapes so that it is easier for kids to swallow the pills.
Jobs may also be taken from too much advancement of technology in the medical field as well. Certain robotic advancements have been proven to be more reliable than the naked eye in some situations. So these hospitals have turned from using doctors to using robots for certain procedures instead. Robots have also been shown to be cheaper over time than having a human on a salary. Businesses may look at this as a business move and move more towards robotic advancements instead of hiring certain people for jobs. The way the government and certain companies look at it is “why would I hire a person for the job when a robot is more reliable and also cheaper than a human?”. This will cripple many blue-collar jobs such as surgeons and could hurt the medical field for job openings. Something about having a doctor perform complicated surgeries is also better though because if a robot has a malfunction, it could possibly end someone’s life. But overall, the future of medical technology is in the right hands and is moving in the right direction.
