5 Medical devices which you might not have realized changed the world

Medical devices are key in today medical industry, we uses these devices in almost everything we do regarding medicine. For example, we use a thermometer to measure our temperature. However, here are 5 key medical devices that changed the world!

Hypothermic needle

This medical device has been around for centuries; it is constantly being updated and improved. Not many people know that the hypothermic needle was first invented by the ancient Greeks and Romans, well a precursor of the devices we know now. They used thin, hollow tools to introduce fluids into the body; from this the hypothermic needle was later invented in the mid-1800s by Charles Pravaz and Alexander Wood.

The next medical device is very interesting and probably something you would not guess, but it’s so simply, you might even be wearing them now…

Glasses

Yes glasses, so simple we use spectacles for two main reasons: vision correction and eye protection or maybe in some cases just a fashion statement. Regardless, the sole purpose is to improve our vision and general improve our quality of life.

The next device is very common just like glasses, it is also something to do with our senses; I’m absolutely sure that you’ve HEARD of it… Guessed what it is?

Hearing Aids

You guess it! The hearing aid, also known as a hearing instrument, is a device designed to amplify sound. Fun fact, Miller Reese Hutchinson invented the first electronic hearing aid made of a carbon microphone, battery and ear set in 1899. In Europe, about 71 million adults aged 18 to 80 years have a hearing loss greater than 25 db.

Onto the third device, what could it be?

PROSTHETICS AND IMPLANTS

This device is fantastic, the creation of prosthetic limbs has given amputees, who would otherwise be dependent on crutches or wheelchairs, a chance to regain their mobility. Given back their independence back and given them the chance to work in a industry which previously they were physically unable to. Now futuristic prosthetic limbs even have inbuilt myoelectric sensors that process brain signals to automatically carry out tasks such as gripping and walking.

The last medical device, what is it? Well here’s a clue, it involves blood sugar.

BLOOD GLUCOSE MONITOR

Did you guess it? Well this last device is very important when monitoring blood sugar levels. To keep their blood sugar levels as close to normal as possible, diabetics need to monitor the level of glucose in their blood at least three times a day, once in the morning, the afternoon and the evening. Doing so they can see were their levels are and whether or not they need to increase their sugar intake or decrease it. However, this device is not only for diabetics, when going to go into hospital they monitor your blood sugar to make sure it is in the right level.
