Insulin Syringe – Terumo

Description

An insulin syringe is a medical device specifically designed for the precise injection of insulin into the body. It is used by individuals with diabetes to manage blood sugar levels by administering insulin, a hormone that helps regulate glucose. Insulin syringes are typically used for subcutaneous (under the skin) injections and are designed for single-use.

Key Components of an Insulin Syringe:

1. Barrel:
   • The barrel is the hollow, cylindrical part of the syringe that holds the insulin. It has markings in units to help measure the exact dose of insulin, usually in increments of 1 or 2 units, depending on the syringe size.
2. Plunger:
   • The plunger is a movable rod inside the barrel that is used to draw insulin into the syringe and push it out during injection. Pulling the plunger back draws insulin into the syringe, and pushing it forward delivers the insulin into the body.
3. Needle:
   • The needle is attached to the end of the syringe and is used to penetrate the skin for the injection of insulin. Insulin syringes have very fine, short needles designed to minimize pain and discomfort during use.
4. Hub:
   • The hub is the part of the syringe where the needle is attached to the barrel. On an insulin syringe, the needle is typically permanently attached.
5. Cap:
   • A cap covers the needle to keep it sterile before use and prevent accidental needle sticks.

Types of Insulin Syringes:

Insulin syringes come in different sizes, depending on the dose of insulin a person needs to inject. The capacity is measured in units, and common syringe sizes include:

1. 0.3 mL Syringe (for up to 30 units of insulin):
   • Suitable for people who require smaller doses of insulin.
2. 0.5 mL Syringe (for up to 50 units of insulin):
   • For individuals who need moderate doses of insulin.
3. 1 mL Syringe (for up to 100 units of insulin):
   • Designed for those who require larger doses.

Needle Length and Gauge:

• Needle Length: Insulin syringes typically have shorter needles, ranging from 4mm to 12.7mm, to ensure that insulin is injected into the subcutaneous layer of the skin rather than deeper into muscle tissue.
• Needle Gauge: The gauge refers to the thickness of the needle. Common gauges for insulin syringes range from 28G to 31G, with higher gauge numbers representing thinner needles that cause less discomfort.

How to Use an Insulin Syringe:

1. Prepare the Syringe:
   • Wash your hands to ensure cleanliness.
   • Remove the cap from the insulin vial and clean the rubber stopper with an alcohol pad.
   • Draw air into the syringe by pulling the plunger to match the number of insulin units you need.
2. Draw Insulin:
   • Insert the needle into the insulin vial and push the plunger to release the air into the vial. This makes it easier to draw insulin.
   • Turn the vial upside down and pull the plunger to draw the prescribed amount of insulin into the syringe.
3. Remove Air Bubbles:
   • Tap the syringe gently to move any air bubbles to the top, and then push the plunger slightly to remove them.
4. Injection:
   • Choose an injection site (typically the abdomen, thighs, or upper arms).
   • Pinch the skin and insert the needle at a 45-degree or 90-degree angle, depending on the length of the needle and the patient’s body type.
   • Slowly push the plunger to inject the insulin, and then remove the needle.
5. Dispose Properly:
   • After use, dispose of the syringe and needle in a sharps container to avoid injury and contamination.

Advantages of Insulin Syringes:

1. Precise Dosing:
   • Insulin syringes have clear unit markings that allow for precise measurement of insulin doses, essential for effective diabetes management.
2. Ease of Use:
   • They are designed to be simple and easy to use, even for people with minimal medical training or dexterity issues.
3. Minimized Pain:
   • Insulin syringes use ultra-fine, short needles that reduce the pain and discomfort associated with injections.
4. Cost-Effective:
   • Insulin syringes are relatively inexpensive compared to other insulin delivery devices such as insulin pens or pumps.

Disadvantages:

1. Single Use:
   • Insulin syringes are designed for single use, which means they need to be replaced frequently.
2. Manual Dosing:
   • Unlike insulin pens or pumps, insulin syringes require manual measurement of the dose, which can be prone to user error if not done carefully.
3. Disposal Issues:
   • Improper disposal of needles and syringes can pose health risks, so it’s important to use appropriate sharps containers.

Conclusion:

An insulin syringe is a vital tool for people with diabetes who require insulin injections to control their blood sugar levels. It provides a simple, cost-effective, and precise way to administer insulin, helping patients manage their condition effectively. Proper use and disposal are essential to ensure safety and
