NEEDLE 22G

How NEEDLE 22G Works

• The 22G needle is a hypodermic needle characterized by its gauge, which indicates the diameter of the needle bore. The 'G' stands for Gauge, and the number 22 refers to a specific diameter. A 22G needle has a relatively small bore, making it suitable for various medical procedures. This size strikes a balance between minimizing patient discomfort and allowing for efficient fluid transfer. The functionality of a 22G needle centers around its ability to pierce the skin and underlying tissues to deliver medication, draw blood, or administer fluids directly into the body. The sharp, beveled tip of the needle facilitates smooth and atraumatic insertion, reducing pain and tissue damage. The hollow bore allows for the passage of fluids, whether it's injecting a drug, withdrawing a blood sample, or delivering intravenous fluids.
• The effectiveness of a 22G needle depends on several factors, including proper technique and the specific application. When used for injections, the needle is connected to a syringe containing the medication. Upon insertion into the targeted tissue (e.g., subcutaneous or intramuscular), the plunger of the syringe is depressed, forcing the medication through the needle's bore and into the body. For blood draws, the needle is typically attached to a vacutainer or syringe. Once the needle is inserted into a vein, the vacuum in the vacutainer or the manual pull of the syringe plunger draws blood through the needle and into the collection tube or syringe. The precise gauge of the 22G needle ensures that the flow rate is appropriate for most common medical applications. Its diameter minimizes the risk of hemolysis (rupture of red blood cells) during blood collection while still enabling relatively quick fluid transfer.
• The materials used in manufacturing 22G needles also contribute to their functionality and safety. Medical-grade stainless steel is the standard material due to its biocompatibility, strength, and resistance to corrosion. The needle's surface is often coated with silicone to reduce friction and further ease insertion. Sterilization is a crucial step in the manufacturing process to prevent infections. Needles are typically sterilized using methods like ethylene oxide gas or gamma irradiation. Proper disposal of used 22G needles is essential to prevent accidental needle sticks and the spread of bloodborne pathogens. Healthcare facilities follow strict protocols for needle disposal, using sharps containers to safely contain and dispose of used needles. The design, materials, and manufacturing processes of 22G needles are all geared toward ensuring safe and effective medical procedures.

While a 22G needle is generally well-tolerated, potential side effects at the injection site may include: pain, bruising, bleeding, redness, swelling, and infection. Less common side effects could involve nerve damage (resulting in temporary or, rarely, permanent numbness or tingling), allergic reactions (ranging from mild rash to severe anaphylaxis), and vasovagal syncope (fainting). Psychological distress such as anxiety or fear related to the injection procedure can also occur. It's crucial to consult a healthcare professional if you experience any concerning symptoms after needle use. Side effects depend greatly on the substance injected and the injection location.

• Since NEEDLE 22G is a medical device and not a medication, the concept of a 'missed dose' does not apply. This product is used for specific medical procedures as needed by healthcare professionals. If you have concerns about your procedure schedule, please consult with your doctor or healthcare provider.

• Keep NEEDLE 22G away from the reach of children and pets.
• Store NEEDLE 22G at room temperature.

• **Choose the Right Gauge:** A 22G needle is suitable for intramuscular (IM) and subcutaneous (SubQ) injections of moderately viscous solutions. Ensure it aligns with the medication's viscosity and your healthcare provider's guidance.
• **Prepare the Injection Site:** Clean the injection site thoroughly with an alcohol swab in a circular motion, moving outward from the center. Allow the alcohol to dry completely before injecting to minimize the risk of infection.
• **Master the Injection Angle:** For IM injections, use a 90-degree angle. For SubQ injections, a 45-degree angle is typically recommended. Consult your healthcare provider for the correct angle based on the injection site and needle length.
• **Minimize Discomfort:** Relax the muscles around the injection site to reduce pain. Inject the medication slowly and steadily. Apply gentle pressure to the injection site with a clean cotton ball after removing the needle.
• **Proper Disposal is Key:** Always dispose of used needles in a designated sharps container. Never recap, bend, or break needles before disposal to prevent accidental needlestick injuries. Contact your local waste management or healthcare provider for safe disposal options.
• **Inspect Before Use:** Before using a 22G needle, always inspect the packaging for any signs of damage or tampering. Ensure the needle is not bent or damaged. Do not use the needle if the packaging is compromised.
• **Check for Air Bubbles:** After drawing medication into the syringe, check for air bubbles. Gently tap the syringe barrel with your finger to move any air bubbles to the top, then expel them by slowly pushing the plunger until the medication reaches the tip of the needle.
• **Rotate Injection Sites:** If you require frequent injections, rotate injection sites to prevent lipohypertrophy (lumps under the skin) and skin irritation. Keep a record of your injection sites to ensure proper rotation.
• **Stay Hydrated:** Staying well-hydrated can help make injections less painful and easier to administer, particularly for subcutaneous injections. Proper hydration improves skin elasticity.
• **Consult Your Healthcare Provider:** If you experience persistent pain, redness, swelling, or any other unusual symptoms at the injection site, consult your healthcare provider immediately. Do not attempt to self-treat any complications.

• There are no known interactions between NEEDLE 22G and food. You can use NEEDLE 22G regardless of when you eat.
