Medical hypodermic needles

Types of medical hypodermic needles

Medical hypodermic needles are available in various types to suit different medical needs and preferences. Some essential types of these needles include:

• Regular Hypodermic Needle

  This is the most common type of hypodermic needle, used for general-purpose injections and blood withdrawals. They are available in various gauges and lengths to suit different needs.

• Insulin Needle

  These are short, very fine needles used with insulin syringes or insulin pens to inject insulin into diabetic patients. They are specially designed to deliver insulin with minimum pain and discomfort.

• Blunt Needle

  These needles have a blunt tip and are primarily used for reconstituting vials, transferring fluids between containers, or any procedure that does not require penetrating the skin or tissue. Their bluntness reduces the risk of damage to the tissues or the vials.

• Epidural Needles

  These are specially designed for epidural and spinal anesthesia injections. They have a unique cutting edge or a pencil point tip to facilitate a precise puncture of the dura mater in the spinal column.

• Spinal Needles

  These are used for lumbar punctures (spinal taps) to collect cerebrospinal fluid or administer medications. They have varying lengths and gauges, with some featuring a stylet to protect the needle tip during insertion.

• Safety Needles

  These needles have a safety mechanism that either retracts the needle after use or covers it with a sheath. They are designed to reduce the risk of needlestick injuries to healthcare workers and are often used in conjunction with other safety devices.

• Winged Infusion Needles (Butterfly Needles)

  These consist of a plastic or metal hub with two plastic "wings" attached to the needle shaft, commonly used for short-term venous access, such as during blood draws or IV insertions. The wings facilitate better control and stability during needle insertion.

How to choose medical hypodermic needles

Medical professionals should consider the following factors when choosing medical hypodermic needles:

• Intended Use

  Consider what the needle will be used for. Needles with small gauges are suitable for drawing blood or transferring thick medicine. Larger-gauge hypodermic needles will be needed for IV fluids, injections, or blood donations. Needles with larger gauges are better for IV fluids, injections, and blood donations.

• Length and thickness

  Think about the needle's length and thickness. Needles that are too long can hurt muscle or nerve tissue. Shorter needles may not reach the muscle or vein if the skin is thick. Needles with thicker shafts (the part above the needle) may cause more pain when inserted, but they work better for drawing blood. Needles that are thicker may also be needed for thicker medicine or IV fluids.

• Needle design

  Some needle designs can make the process easier and more comfortable for patients. Needles with a sharper point can reduce tissue damage and pain. Special coatings on the needle, like silicone, can make it easier to insert and reduce friction.

• Professional training

  The healthcare professional's training and experience also matter. A doctor who specializes in injections may be able to use a larger-gauge needle with less discomfort than a nurse who only gives occasional injections. Consider the person's past experience and training when deciding on needle gauge.

• Needle disposal

  Think about how the needle will be disposed of after use. Needles that are reused many times, like those used for insulin, should have a special disposable sheath that covers the needle safely. This prevents needle-stick injuries to patients and staff. For single-use needles, there should be a sharp container nearby for proper disposal. Used needles should never go into the regular trash.

How to use, install, and product safety

To ensure the safe delivery of medication or fluid through a syringe, the hypodermic needle must be used correctly. Below is a step-by-step process on how to use it safely:

• Prepare the Syringe and Needle

  Carefully remove the needle cap without bending the needle. Do not touch the exposed part of the needle. Attach the needle to the syringe firmly. Ensure there are no air bubbles in the syringe by holding it upwards and tapping it with a finger.

• Clean the Injection Site

  Use an alcohol swab to clean the area where the needle will be injected. Wait for the alcohol to dry. This will help prevent any form of infection from entering the body during the injection.

• Insert the Needle

  Pinch or stretch the skin around the injection site. At the desired angle (usually 90 degrees for muscle injection and 45 degrees for fat tissue), insert the needle swiftly into the skin. Do not hesitate while inserting the needle as it will cause pain.

• Inject the Medication

  Once the needle is inserted, push the plunger on the syringe to inject the medication. Observe for blood return in the syringe. If there is a blood return, it means the needle is in a blood vessel. Pull out the needle and insert a new one, then repeat the injection process.

• Withdraw the Needle

  After injecting the medication, remove the needle swiftly. Do not bend or twist it. Apply pressure to the injection site with a cotton ball or gauze to stop the bleeding. Dispose of the needle in a sharps container.

Product Safety

The 16 gauge hypodermic needle is sharp and poses a risk of injury if not handled properly. Therefore, it is recommended that users follow these safety precautions.

• Always use the needle for its intended purpose. Do not attempt to use it for any other reason.
• Ensure the needle is sterile before use. Any sign of contamination means the needle should not be used.
• Avoid bending or recapping the needle after use. This increases the risk of injury.
• Always dispose of the needle in a designated sharp container.
• Follow the manufacturer's instruction on the packaging to avoid mistakes during the injection process.

Functions, features, and design of medical hypodermic needles

Medical hypodermic needles have many vital functions and features that help medical professionals perform various medical procedures. Below are some of them:

• Needle gauge: The gauge size determines how thick or thin the needle is. Hypodermic needles come in different sizes to suit various medical procedures. Needles with a thicker gauge draw blood easily and administer drugs, while thinner needles offer painless injections during vaccinations.
• Needle length: The length of the needle determines how deep it will penetrate into the body. Needles with a longer length are used for deep intramuscular injections, while shorter needles are used for subcutaneous and intramuscular injections.
• Needle tip: Needle tips are designed to perform different medical procedures. The procedure determines the kind of needle tip that medical professionals will use. Some needle tips include a bevel tip, a cutting wedge, and a blunt tip.
• Bevel angle: The bevel angle is mainly used in needle tips. It determines how the needle will penetrate the skin. A smaller angle with a sharper bevel makes the needle penetrate the skin quickly and cause less pain to the patient.
• Safety features: Some hypodermic needles have safety features to prevent needle stick injuries. This includes self-sheathing needles that cover the needle after use or locking mechanisms that prevent the needle from being detached from the syringe.
• Packaging: Hypodermic needles are sterilized and packed in different kinds of packaging. The packaging helps prevent the needle from getting contaminated before use. Needles are packed in single and double packaging, which is often plastic or foil.

Q&A

Q1: What is the shelf life of a disposable hypodermic needle?

A1: The hypodermic needle's shelf life depends on its type and how it's stored. Generally, the needle is usable within 2 to 3 years from its date of manufacture. However, those stored under extreme temperatures may degrade faster than those stored at room temperature.

Q2: Can hypodermic needles be reused?

A2: Hypodermic needles are designed for single use only. Using them more than once compromises their safety and effectiveness. In some cases, reusing a hypodermic needle can increase the risk of infection and cause more pain to the patient during the injection.
