Syringes for Injection and Aspiration
Plastic syringes with Luer or Luer-Lock connectors are essential consumables used across nearly all medical disciplines. Available as two-part or three-part syringes, they offer versatile applications for both clinical and procedural use.
Medical syringes are not only used for injecting medications and vaccines but also for blood collection and wound irrigation. Most syringes are sterile, single-use products, ensuring safe disposal after use and reducing the risk of infections and cross-contamination.
At Praxisdienst, we provide a wide range of syringes in various sizes and volumes for use in clinics, hospitals, and medical practices. Options include sterile individually packed syringes as well as non-sterile syringes available in bulk packs.
Single-Use Syringes
Conventional single-use syringes are available in two-part or three-part designs. Two-part syringes consist of a transparent barrel and plunger, usually starting at volumes of 2–3 ml, and are often sterile. They are ideal for routine medication injections in daily clinical work.
Three-part syringes include additional sealing rings that enhance smooth operation, making it easier to draw and inject small volumes accurately. Standard syringes do not come with pre-attached needles and are individually sterile-packed. Both Luer-slip and Luer-Lock versions are available, as well as PVC- and latex-free options.
Syringes for Irrigation
Wound and bladder syringes feature large volumes of typically 50 or 100 ml and are primarily used for irrigation rather than injections. They are ideal for rinsing wounds after surgical procedures or for flushing catheters and bladders in urological applications. These syringes often come with a catheter connector and can be converted to a Luer fitting using an included adapter.
Syringes for Oral Administration
Disposable oral syringes are specifically designed for administering liquids and medications orally and are not suitable for subcutaneous, intramuscular, or intravenous use. Oral syringes are easily distinguishable by a distinctively coloured plunger—for example, the Exadoral syringes from B. Braun have a purple plunger for clear identification.
Fine Dosing Syringes
For medications requiring very small volumes, offer scales accurate to hundredths of a millilitre. Many feature a spare plunger to minimize residual liquid.
Common examples include heparin syringes, which use unit-based scales rather than millilitres. Pressure injectors are also considered precision dosing syringes and provide a needle-free method for subcutaneous injection at 4–6 mm depth, forming a small wheal.
Insulin Syringes
Insulin syringes are a type of precision dosing syringe. They are widely used in hospitals and clinics as an alternative to insulin pens or pumps. Insulin syringes allow for combined dosing of short-acting and long-acting insulin, reducing the number of daily injections for patients.
Special U-40 insulin syringes are designed for patients requiring small doses, often children. Both U-100 and U-40 syringes feature integrated needles for direct drawing and administration.
Applications
Syringes are used for:
- Medication injections
- Irrigation (e.g., wounds, catheters)
- Collection of body fluids (blood, cerebrospinal fluid)
- Sampling of tissue (needle biopsies)
- Fixation of catheters, balloon probes, or tracheal tubes
- Infusion of fluids
- Analytical procedures (biomonitoring)
