Types of Medical Needles

Sep 12, 2021

There are six major types of syringe needles. Four have a sharp bevel shape stainless steel tip for piercing the skin and tissue. The fifth type is a blunt needle used for cannula. Blunt tips come in plastic or metal. The last type is a safety tip that shields the needle from accidental sticks.

1. Regular bevel is the most common tip type. Subcutaneous and intramuscular injections are the typical use of this bevel type.

2. Short bevel tips offer specialty applications such as arterial blood gas sampling or nerve blocks. Its design supports minimal injection depth and rapid withdrawal and fluid dispersion.

3. Intradermal bevel provides for shallow and low angle insertions just below the epidermis. This needle tip offers a good method for testing skin for allergies.

4. 5-bevel has a flatter, thinner surface found to be less painful for patients.

5. Blunt tips or dispensing needles prepare and dispense medications to patients usually through an IV device instead of being injected directly into the patient. These tips are safer for caregiver use since they do not have a sharp tip.

6. Safety tips protect the user from accidental stick injuries. They are available in retracting, shielding, and sliding sleeves.
