Insulin is a hormone that helps the body process sugar, or glucose. It’s used to treat diabetes and manage blood sugar levels.
An insulin pump closed loop is a type of medical device used to deliver insulin to people with diabetes. Much like a traditional pump, the user can create an infusion set and program their own doses. As per Tandem Diabetes experts, “Closed-loop system is sometimes referred to as an artificial pancreas.”
The difference between this type of pump and other types is that it works in tandem with a continuous glucose monitor (CGM), which monitors blood sugar levels and delivers insulin when needed. This technology effectively prevents hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar), as it knows exactly how much insulin should be delivered based on current data from the CGM.
Flowing liquid insulins
Flowing liquid insulins are delivered by insulin pens, jet injectors, and syringes. Insulin pens are small devices that hold a cartridge of insulin and look like a pen. They’re used to inject the right amount of insulin into your body in one quick motion.
Insulin jet injectors contain a reservoir for storing insulin and an advanced needle system that uses air pressure to push out the exact amount of insulin you need for each injection. To use this device, you place it on your thigh or abdomen, then press down firmly until you feel a slight prick from delivering the correct dose of medication into your body.
Inhaled insulin is a new type of insulin delivery device that allows the body to absorb insulin directly into the bloodstream through the lungs. It can be used to treat diabetes in people who have difficulty injecting or who want to avoid injections altogether.
The FDA has approved inhaled insulin, which delivers a high concentration of fast-acting insulin into your lungs when you breathe out. When you inhale, air flows through a device containing dry particles of human recombinant (synthetic) rapid-acting insulin analogs, which are absorbed directly into your bloodstream without going through your stomach or intestines.
Implantable insulin pump
An implantable insulin pump is implanted under the skin to deliver insulin continuously. It can be programmed to deliver a set amount of insulin over a set period of time, or it can deliver different amounts at different times. For example, if you’re eating something high in carbohydrates and need more insulin to counteract their effects, you can program your pump to give you an extra burst before or during the meal.
Like other types of delivery devices, an implantable pump continues delivering insulin until all the excess sugar has been cleared from your bloodstream (which takes about four hours). The device is typically removed through surgery once its use is no longer needed (for example, after someone has recovered from surgery).
Insulin delivery devices are an important part of diabetes management, and it’s important to know which one is right for you. For example, if you have a busy schedule and don’t want to carry around multiple pens or syringes, then using an insulin pen might work well for you. But, on the other hand, if your daily routine allows time and convenience aren’t as much of an issue—or if your budget can support it—then an insulin pump may be better suited for your needs.
