Insulin pen is a device which is used to alleviate the condition of type 1 diabetes, which is caused due to deficiency of insulin in the body. It is generally taken by patients when their blood sugar levels fall below 70mg/dL. Let us discuss in brief the components of this pen followed by its working mechanism.

Components of insulin pen

There are mainly five components in insulin pen

1. Cartridge: It is used to hold specified insulin prescribed by a physician to his/her patient.

2. Cartridge holder: It is the body of the pen which supports cartridge to be in a position.

3. Needle: Used to inject insulin. It disposable in nature which is screwed to the cartridge every time a patient injects insulin.

4. Dial: It is used to set and measure the required dosage of insulin

5. Knob: When a knob of insulin pen is pushed, needle injects the insulin into our body.

How does insulin pen work?

Insulin pen is generally injected into the subcutaneous tissue. It is a kind of fatty tissue located under the skin between our skin and muscle. It is preferred to inject insulin in the fatty tissues because these tissues absorb insulin quickly and enhances the chances of getting a right dosage. Therefore, they must be injected into fatty tissues besides muscles as it might hinder the performance of insulin.

Steps to follow while using insulin pen

There are necessary steps to be followed before using insulin pen

1. You need to wash our hands and choose a hygienic place for injecting insulin.

2. You need to be sure of the kind of insulin you are prescribed to take.

3. You need to check whether insulin is clear or cloudy, if cloudy you need to rub it between your palms for 1 minute to make it clear. Shaking of insulin pen must be avoided

4. You need to get alcohol wipes and disposable needles

5. Insert the needle into the cartridge carefully by removing its paper tab. Remove the outer cap after fixing the needle and then remove the inner cap.

6. You need to prime the pen. Priming is a phenomenon which is used to remove air bubbles in needle to make sure that the needle is working properly. In order to prime the needle you need to push the knob of pen and should allow at least 1-2 drops to appear. Then, adjust the required dosage level with the help of knob.

7. You need to select the appropriate area for injecting insulin. Mostly insulin is injected in abdomen, front and side of thighs, upper arm and outer arms. You need to rotate your injection sites because using the same area for injection might harden the tissue under the skin and can affect the working of insulin. Also, areas with scars and moles must be avoided as this might hinder the performance of insulin. After selecting your perfect site, inject the insulin carefully into the body.

8. Then you need to wipe the injected area with an alcohol wipe and place a bandage over the spot if necessary when you observe bleeding.

9. You need to unscrew the used needle and replace the outer cap. Discard the needle into your bin.

10. Store your pen at room temperature and avoid too hot and too cold areas as this might affect the functioning of insulin.

As soon as the insulin enters our body it starts working and controls the blood glucose/sugar levels. It makes the whole process very easy to a type-1 diabetic patient. What he/she needs is a simple shot of insulin from his/her pen.
