Types of syringes

Syringes come in various types and sizes, each designed for specific medical purposes. Here are common types of syringes:

1. **Standard Syringes:**
– **Luer Lock Syringes:** Feature a threaded tip that securely locks the needle in place, preventing accidental disconnection.
– **Luer Slip Syringes:** Have a smooth tip without threads, where the needle is pushed onto the syringe.

2. **Insulin Syringes:**
– **Insulin Syringes:** Specifically designed for administering insulin. They have a fine needle and are calibrated to allow for accurate dosage measurements.

3. **Tuberculin Syringes:**
– **Tuberculin Syringes:** Graduated in tenths of a milliliter and used for small-volume injections, such as tuberculin skin tests.

4. **Eccentric Syringes:**
– **Eccentric Syringes:** Feature an offset nozzle, allowing for more comfortable subcutaneous injections.

5. **Pre-Filled Syringes:**
– **Pre-Filled Syringes:** Come pre-loaded with a specific dosage of medication, making them convenient for self-administration.

6. **Safety Syringes:**
– **Retractable Safety Syringes:** Have a mechanism that retracts the needle into the syringe barrel after use, reducing the risk of needlestick injuries.

7. **Glass Syringes:**
– **Glass Syringes:** Made of glass and suitable for specific medical applications, often used in laboratory settings.

8. **Plastic Syringes:**
– **Plastic Syringes:** Made of plastic materials, commonly used for various medical purposes, including injections and fluid aspiration.

9. **Catheter Tip Syringes:**
– **Catheter Tip Syringes:** Have a larger opening at the tip, suitable for administering medications through catheters or feeding tubes.

10. **Becton Dickinson (BD) Syringes:**
– **BD Syringes:** A popular brand of syringes, offering various types including insulin syringes, tuberculin syringes, and more.

11. **High-Pressure Syringes:**
– **High-Pressure Syringes:** Designed to withstand high pressures and are often used for contrast media injection in medical imaging procedures.

12. **Safety Retractable Syringes:**
– **Safety Retractable Syringes:** Combine the features of safety syringes with a retractable mechanism for needle safety.

13. **Oral Syringes:**
– **Oral Syringes:** Designed for accurate measurement and administration of liquid medications orally, often used for pediatric or geriatric patients.

14. **Positive Displacement Syringes:**
– **Positive Displacement Syringes:** Used for accurate measurement and dispensing of highly viscous substances, such as oils or creams.

15. **Air-Tite Syringes:**
– **Air-Tite Syringes:** Designed to prevent air from entering the syringe during aspiration, ensuring accurate dosage measurements.

Selecting the appropriate type of syringe depends on the specific medical application, dosage requirements, and the nature of the medication being administered. Healthcare professionals consider factors such as needle gauge, syringe volume, and special features when choosing the most suitable syringe for a given situation.
