Insulin Syringes .5ml

Insulin Syringes 0.5ml are precision-engineered medical devices designed for safe, accurate, and comfortable insulin administration. With a 0.5ml (50 units) capacity, these syringes are ideal for patients who require smaller, more precise insulin doses.

A 0.5 mL insulin syringe is a medical device designed specifically for the subcutaneous (under the skin) injection of insulin.

High Quality – Made of durable plastic material, clear & well-printed measuring marks, and smoothly working plunger.

 

Key Characteristics

Volume Capacity: The syringe can hold a maximum of 0.5 milliliters (mL) of fluid, which is equivalent to 50 units of U-100 insulin.

Purpose: It is used by people with diabetes to precisely measure and inject their prescribed dose of insulin.

Gauge and Length: Like all insulin syringes, it features a very fine needle (high gauge) and is typically short to ensure the injection is delivered into the subcutaneous fat layer and not into muscle, which can affect insulin absorption.

Needle Permanence: The needle is permanently fixed to the syringe barrel, which minimizes medication waste and helps ensure sterility.

Measurement Markings

The 0.5 mL syringe is specifically designed for smaller to moderate insulin doses.

Markings: The syringe barrel is marked with lines to indicate the units of insulin.

Scale: Because its maximum capacity is 50 units, the markings are usually more widely spaced than those on a 1 mL (100-unit) syringe, making it easier for users, especially those with visual difficulties, to draw up precise doses. Each line on the scale typically represents 1 unit of insulin.

When It’s Used

This size is commonly recommended for individuals whose typical single insulin dose is 50 units or less. Using a syringe that closely matches the dose size helps ensure greater accuracy.

Detailed Description of a 0.5 mL Insulin Syringe

A 0.5 mL insulin syringe is a specialized, sterile, single-use, disposable medical instrument crucial for diabetes management.

Dosing Accuracy and Scale

Capacity: It holds a maximum of 50 units of U-100 insulin (0.5 mL).

Graduation: The barrel features a clear, black graduated scale with markings typically representing 1-unit intervals.

Precision: This smaller capacity barrel with widely spaced lines is specifically chosen to improve dosing accuracy for individuals who take 30 to 50 units in a single injection. If a person’s dose is consistently 50 units or less, using the 0.5 mL syringe over a larger 1 mL (100-unit) syringe reduces the risk of misreading the markings.

Needle Specifications (Common)

The needle is permanently fixed (crimped or welded) to the syringe body, which eliminates dead space—the small volume of medication that can be left in the hub of a detachable-needle syringe.

Feature	Common Specifications	Implication
Gauge (G)	29G, 30G, or 31G	High gauge indicates a very thin needle, which is designed to minimize pain and discomfort during injection.
Length	8 mm (5/16 inch) is most common, but can range from 6 mm to 12.7 mm.	Shorter lengths (e.g., 6 mm or 8 mm) are preferred for insulin to ensure the medication is delivered into the subcutaneous fat layer and avoids the muscle, regardless of the patient’s BMI.
Design	Ultra-sharp, triple-beveled	The needle tip is sharpened from three angles to allow for smoother, easier penetration of the skin.

Material and Construction

Composition: Syringes are non-toxic, non-pyrogenic, and often latex-free. They are typically made from medical-grade materials such as polypropylene (barrel, plunger) and stainless steel (needle).

Barrel Transparency: The clear, transparent barrel allows the user to easily inspect the insulin for cloudiness (if using mixed insulins) and accurately check for air bubbles before injection.

Lubrication: The needle is often coated with a Micro-Bonded lubrication to facilitate a smoother and more comfortable entry and withdrawal from the skin.

Plunger/Piston: The syringe uses a snug, dual-lip seal (gasket) on the plunger to ensure a perfect seal for controlled aspiration and injection.

Safety and Disposal

Sterility: Each syringe is individually packaged in a sterile blister pack (often in boxes of 100).

Single-Use: Insulin syringes are designed for one-time use only to maintain sterility, needle sharpness, and to prevent infection or needle blunting.

Disposal: Used syringes must be disposed of immediately in a designated sharps disposal container (a puncture-proof receptacle) according to local medical waste regulations.

In summary, the 0.5 mL insulin syringe is a high-precision tool tailored for moderate insulin doses (up to 50 units), designed with ultra-fine, short needles for optimal comfort and the safest possible subcutaneous injection.
