Syringes

Description

The administration of drugs to the body can occur through various routes, including enteral, parenteral, transdermal, and inhalation. Parenteral routes offer advantages like rapid drug effects, 100% bioavailability, protection from the gastrointestinal system, and prevention of drug inactivation before reaching the desired site. Plastic syringes, classified as Class IA medical devices, are commonly used for parenteral drug administration.

General-purpose syringes are often disposable and constructed from materials like polypropylene, although other materials may be used. These versatile syringes have a wide array of applications, but it’s important to note that not all uses are suitable for disposable, single-use general-purpose syringes. General-purpose syringes are designed with versatility in mind, making them suitable for a wide range of applications. They are not limited to a single specific use but can be effectively employed in various settings. These syringes are used in compounding pharmacies and industrial manufacturing to healthcare settings, including vaccine injections and intravenous (IV) treatments.

Types of Syringes:

Syringes come in various types, classified based on their volume and intended usage. The two main categories are disposable syringes and non-disposable syringes. Disposable syringes are sterile, pre-packaged, ready for use, non-toxic, non-pyrogenic, and carry a lower risk of transmitting diseases like AIDS or Hepatitis B, making them the preferred choice. Non-disposable syringes are typically constructed from heat-resistant materials such as borosilicate glass and are less commonly used.

Syringes are categorized into two main types based on their intended use: oral and hypodermic syringes.

Oral Syringes: These syringes are specifically designed for efficiently administering drugs via the oral or enteral route. They are also suitable for preparing drugs with very small volumes.

Hypodermic Syringes: Hypodermic syringes are calibrated in cubic centimetres (cc), millilitres (ml), or units. Syringes with small volumes, such as 1, 2, 2.5, and 3 ml, are used for intramuscular (i.m.) or subcutaneous (s.c.) injections. Syringes with larger volumes, typically 5, 6, 10, and 12 ml, are employed for drawing blood from patients or for preparing drugs for intravenous (i.v.) injections. Syringes with volumes exceeding 20 ml are utilized for injecting larger volume sterile solutions. The choice of syringe volume depends on the specific medical procedure and dosage requirements.

Based on their special intended use, there are three main types of syringes: Insulin syringes, Tuberculin syringes, and pre-filled syringes.

Insulin Syringes: These syringes are designed specifically for the injection of insulin hormone. They are commonly used in the treatment of Insulin Dependent Diabetes Mellitus and are calibrated by units.

Tuberculin Syringes: This type of syringe is used primarily for the diagnosis of tuberculosis. These syringes typically have a volume of 1 ml, and the syringe barrel is marked with 100 lines, each representing 0.01 ml. Tuberculin syringes are primarily used for intradermal (i.d.) injections of very small volume drugs, commonly employed in tuberculosis and allergy tests. They are also a preferred choice for intramuscular (i.m.) injections of drugs with volumes less than 1 ml.

Pre-filled syringes: They are designed for the administration of various liquid drugs, such as insulin or vaccines. These are single-dose cartridges that come with fixed needles. Pre-filled syringes offer several advantages over traditional vials and ampoules, benefiting both patients and healthcare workers.

How to discover the right syringe for your use?

When choosing a syringe type, it’s crucial to consider several factors to ensure it suits your specific application and requirements. Here are key considerations when selecting a syringe type:

• Select a syringe that can hold the required volume of liquid or substance, ranging from microliters to millilitres.
• Syringes can be made of plastic, glass, or metal, each with its own advantages. Plastic syringes are lightweight and disposable, glass syringes are durable and can be sterilized, and metal syringes are used for specialized applications.
• For high-precision applications, choose a syringe with minimal dead volume and a gas-tight feature, ensuring proper handling of sub-microliter samples.
• Decide if you need a syringe with an attached needle or one with Luer lock or Luer slip tips for attaching separate needles.
• Different applications have specific requirements. For example, insulin syringes are for subcutaneous injections, while gas-tight syringes are used in gas chromatography and subcortical infusions in small-animal models.
• Substance viscosity affects syringe choice. Highly viscous liquids may require a syringe with a larger diameter, a robust plunger mechanism, and a compatible needle with a larger inner diameter.
• Consider whether you need a disposable syringe for single use or a reusable one that can be sterilized. This decision impacts cost, environmental impact, and application quality.
• Some syringes come with safety features, mechanisms for preventing overfilling, gas-tight seals for volatile substances, or needle sleeves to minimize dead volume.
• Choose syringes from reputable manufacturers known for quality. High-quality syringes are less likely to leak, break, or provide inaccurate measurements.

Care and Handling Tips for Syringes and Needles:

Syringe Inspection & Maintenance:

• Regularly check for damage and needle tip smoothness.
• Replace PTFE tips with exposed metal.
• Flush the syringe for cleanliness and store it dry.

Cleaning & Unclogging:

• Use appropriate solvents to clean.
• Avoid full submersion to protect adhesive parts.
• Unblock needles with solvent and follow heating instructions.

Syringe Lubrication:

• Do not use grease; opt for compatible solvents.

Accuracy & Precision Tips:

• Hold the syringe by the flange and plunger button.
• Expel air by pumping the plunger with the needle submerged.
• If plunger is removed, clean and reinsert it.
• Be cautious with PTFE tips and avoid touching the plunger.
