BD Ultra Fine 4mm Nano Pen Needles (32G) - Ultra-Thin Wall Pack, 50 Count

BD Ultra-Fine 4mm Nano Pen Needles - 32G (Pack of 50)

BD Ultra-Fine 4mm Nano Pen Needles are world-class, sterile subcutaneous injection interfaces engineered by Becton, Dickinson and Company (BD) to provide an incredibly comfortable, reliable, and anxiety-free drug delivery experience. This retail pack contains 50 individually sealed, single-use pen needles featuring an ultra-thin 32G (0.23mm) outer diameter and a micro-length of 4mm. Built with a standardized screw-on hub configuration, these needles offer a universal fit that locks securely onto all major diabetes insulin and GLP-1 receptor agonist pens.

For individuals requiring daily subcutaneous injections, needle anxiety and injection site pain can present significant hurdles to treatment adherence. Standard or thick needles often pull on skin nerve endings and can accidentally slide into deeper muscle tissue, causing bruising and unpredictable, rapid drug absorption. The BD Nano solves this issue by combining an ultra-short 4mm length with advanced Ultra-Thin Wall Technology. This allows the medication to flow quickly and comfortably into the safe fat layer just beneath the skin, maximizing clinical efficacy while minimizing tissue trauma.

Precision Engineering & Mechanical Attributes

These high-precision pen needles optimize subcutaneous drug delivery through advanced micro-structural engineering:

• Ultra-Thin Wall Technology: Features an expanded inner core diameter encased within a microscopically thin metal wall. This design allows for an uninhibited, fast flow of medication, reducing the thumb pressure and time required to plunge the injection button.

• PentaPoint™ 5-Bevel Needle Tip: Unlike traditional 3-bevel tips, this needle features five distinct, micro-engineered facets that create a slimmer, more aerodynamic profile. This allows the needle to glide through skin tissue with up to 23% less penetration force.

• Micro-Bonded Silicone Lubricant: Coated with a proprietary, smooth silicone formula that eliminates drag and mechanical friction during both insertion and withdrawal, preventing post-injection redness.

• Universal Contoured Screw Hub: Designed with a standard, easy-to-turn thread system that locks tightly onto major delivery devices, including pens from Novo Nordisk, Eli Lilly, Sanofi, and Owen Mumford.

Key Product Benefits

• Maximum Patient Comfort: The ultra-thin 32G gauge and 5-bevel engineering make daily injections virtually unnoticeable and highly tolerable.

• Reduces Intramuscular Risk: The ultra-short 4mm length safely drops medication straight into the subcutaneous fat layer, preventing painful accidental injections into the underlying muscle.

• Eliminates the Skin Pinch: The 4mm profile is clinically proven to be effective without requiring a skin pinch-up before injecting, simplifying your routine regardless of your body mass index ($BMI$).

• Optimized Medication Flow: Advanced internal diameter spacing cuts down injection hold times and guarantees a full, accurate dose with every click.

• Highest Sterile Integrity: Each individual needle is shielded by an outer paper tab and a dual-cap assembly, maintaining complete sterility until the moment of use.

Step-by-Step Injection Guidelines

To maintain complete sterility and ensure a comfortable, leak-free dose:

1. Prep the Site: Wash your hands thoroughly. Clean your chosen injection site (abdomen, thigh, or upper arm) with an alcohol swab and allow the skin to dry completely.

2. Attach the Needle: Peel off the sterile paper seal from the outer cap of the needle. Push and screw the needle straight onto the tip of your pen device until it is firmly secured.

3. Prime your Pen: Pull off the outer cap (save this for removal later) and the inner shield. Turn your pen dial to 2 units, point the needle upward, and tap the cartridge side gently. Depress the plunger fully until a drop of liquid appears to clear any hidden air bubbles.

4. Deliver the Dose: Dial your required units. Hold the pen at a direct $90^\circ$ angle relative to the skin surface and smoothly push the needle all the way in.

5. Count to Ten: Press the injection button down completely. Hold the needle in place for a full 10 seconds before pulling it out to ensure the entire dose is absorbed and to prevent medication leakage.

6. Safe Disposal: Carefully replace the outer needle cap, unscrew the needle counterclockwise, and drop it immediately into an approved sharps container.

Safety Information & Crucial Precautions

• Strictly Single-Use Only: Never reuse a needle. Pen needles are engineered to be used exactly once. Reusing a needle dulls the tip, strips away the lubricating silicone coating, and creates microscopic barbs that tear tissue, increasing the risk of infection and painful fatty lumps (lipodystrophy).

• Never Leave the Needle Attached: Do not store your delivery pen with the needle still screwed on. This can allow air bubbles to enter the cartridge, lead to medication leakage, and alter dosing accuracy.

• Site Rotation Routine: Always rotate your injection sites with every dose. Avoid injecting into areas with visible bruising, stretch marks, scars, or hardened skin lumps.

• Safe Disposal Protocols: Never toss used needles directly into household trash or recycling bins. Always slide them into a puncture-proof biohazard sharps container to prevent accidental needle sticks.

• Storage Protocols: Keep the retail box in a clean, dry cabinet away from high humidity, kitchen heat, or extreme cold. Never use a needle if the individual paper seal is broken or torn. Keep out of reach of children and pets.
