Insulin is a hormone that is manufactured in the pancreas and then released into the bloodstream to help the body use glucose for energy. Insulin was discovered in 1921 by Canadian doctor Frederick Banting and medical student Charles Best, who was trying to find a cure for diabetes. Since this time, many advances have been made in insulin delivery systems, including pens, pumps and continuous glucose monitoring (CGM) devices.
The discovery and development of insulin
Insulin was first discovered by Frederick Banting and Charles Best in 1921. They were awarded the Nobel Prize for Physiology or Medicine in 1923 for their discovery. In 1922, insulin was first used on humans, who experienced a fast recovery from their diabetes symptoms.
The hormone is produced by the pancreas and helps balance blood sugar levels by sending glucose into cells that need it to produce energy. In people with Type 1 diabetes (formerly known as Juvenile Diabetes), there is no longer any insulin production within their bodies—this can be due to genetics, trauma or another unknown cause. So they have no way of controlling their blood sugars without an external source of insulin being introduced into the body via injection or infusion pump systems like those pictured above.
Insulin Pens & Pen needles
Insulin pens were first introduced in the early 1980s. These first-generation pens used a glass cartridge with a plunger to deliver the insulin. The cartridges could only be used once and had to be discarded after use. However, they did give diabetics the ability to carry their insulin around with them, which was a big improvement over having to inject themselves before each meal or snack.
The next generation of insulin pens came onto the market in the late 1990s and used an aluminum cartridge instead of glass. This change made it possible for diabetics to reuse their cartridges multiple times before discarding them (though you should still keep track of how many times you've used your pen so that you can replace it before it expires).
Insulin Pumps
An insulin pump is a small device that delivers insulin through a catheter under the skin. It can be used to provide basal insulin and bolus insulin for meals.
A diabetes insulin pump is programmed to deliver basal and bolus insulin on a schedule or can only deliver basal insulin. Tandem Diabetes professionals say, "Stylish and easy to operate insulin pumps are available for you."
Continuous Glucose Monitoring (CGM) systems
If you have diabetes, you may be familiar with the use of CGM systems. These devices can help you better understand how food and exercise affect your glucose levels.
CGM systems are used to monitor blood glucose levels and can help people manage their diabetes by giving them real-time information about their glucose levels. CGM systems are usually worn on the body, but some systems can be worn on the finger instead of a body part.
Insulin delivery systems have come a long way since their original introduction into the market. From pens to pumps, these devices are helping people manage their diabetes on a daily basis.
Continuous glucose monitoring (CGM) systems are also making their debut, offering new ways for patients with type 1 diabetes to manage their disease. It's exciting times ahead as more options become available and improve the lives of people who suffer from this condition!
