Long ago, when our ancestors were still young, one word about common illnesses, like a cold, caught everyone’s attention. With no medicine to take, it was strong enough to wipe out a whole population since people didn’t have much knowledge on how to cure it. As the years went by, technology in medication improved greatly. Even if someone got cancer, it would be more possible to cure. Doctors would be able to discover the type of cancer and then will be able to treat the patient. Of course, the sooner the disease is discovered, the higher chance of survival.
One of the greatest Canadian inventions of all time is insulin invented by Dr. Fredrick Banting and Dr. Charles Best . Insulin is a hormone located in the pancreas which removes and uses the glucose from the blood. It is used to treat patients with type 1 and type 2 diabetes. Type 1 diabetes is when insulin is no longer produced by the pancreas while type 2 diabetes is when the pancreas doesn’t produce enough insulin or the body doesn’t use the insulin they produced properly. By using insulin, it helps increase the ability to take the glucose of the cells and reduces the long – term complications of diabetes.

People with diabetes would use the insulin injection to control the blood sugar. |
Another Canadian invention would be the inhaler, which is used to treat asthma. It was invented by H.R. Shepperd. It is a very common illness where it is a “chronic inflammatory disease of the airway” that causes people with asthma to have a shortness of breath, tightness in the chest, coughing and/or wheezing. This is where the inhaler comes in. From the mouth, it releases a certain amount of medication in aerosol form. It settles onto the walls of the airways of the lungs, relaxing the muscles to open them up which gives the user a short term relief.

Last but not least, another Canadian contribution to medical technology would be the artificial heart pacemaker. It was invented by John Hopps, designed to do two things; regulate the frequency of the heartbeat so that it beats efficiently; and to correct the bradycardias (slow arrhythmias), which can cause weakness, fatigue or even death. The pacemaker sends tiny precisely – timed electrical signals to the heart whenever the rhythm is slow. Check out the video below to learn more about the pacemaker.
Fortunately for us, with the technology and knowledge today, people are able to develop life saving inventions, even for the simplest illnesses. Maybe in the near future, there would be more inventions by Canadians that can greatly change the medical world.

I agree that technology are changing causing us human to cure almost anything. I like your example about the common flue that could wipe out the whole population. I didn't know what an inhaler does until i read this blog. I think that the inhaler helps many people because wherever i go i see at lease one person with a inhaler. I think that in the future there would be invention that could cure even cancer!
ReplyDeleteI think that all of these inventions mentioned are wonderful and have greatly helped the human race. It is great to see that there are Canadian contributions which proves that we are serious about our health. I think that if technology keeps progressing at this pace, we soon may be able to find a cure for almost any disease or illness. I really enjoyed your post and have learned a lot about the different medical technologies.
ReplyDeleteHey Valerie,
ReplyDeleteI enjoyed reading your blog entry about how the technology increase is starting to help humans stay healthy and cure any complications that humans might have with their health. I do believe that if technology does continue to increase they way it is there will definately be a cure for any sort of disease. I also learned something new from your blog! I did not know that insulin was invented by Dr. Fredrick Banting and Dr. Charles Best.
It's true that the older generations were more concerned about illnesses; nowadays, thanks to free healthcare, we can all afford to go to the doctor and have ourselves checked, in which case we're given a prescription even for the simplest illness. It's almost frightening!
ReplyDeleteEven though progress is great, it's important to remain aware of the side effects--for instance, one of the precautions of antibiotics is that you're not supposed to take antibiotics too often, since the bacteria develop resistance. Here's to more advancements in medical technology!
You have some really good ideas in this article Valerie. Thanks for sharing.
