Understanding the components of syringes and needles

Knowing the engineering of syringes and needles will help you buy confidently online. 

A syringe is composed of three parts, the plunger, barrel, and tip. Keeping the needle tip immersed in the solution, you pull the plunger outwards thus filling the barrel with medication. 

A needle also consists of three parts, the hub, the shaft and the bevel. The hub fits onto the syringe tip, the shaft connects the needle to the hub and lastly the bevel (or slanted tip) creates a narrow slit when injected into body tissue. 

Syringe and needle size selection 

Syringes come in four main different tip types, each with its own job specialization.

Slip tip provides a friction-fit connection. For this tip type, the user has to push the needle hub onto the syringe. There is no locking function. This tip type can also be referred to as the Luer slip syringe and is commonly used for diabtetic uses, post-operative conditions, vitamin deficiencies and intramuscular medication.

Luer lock tip has a threaded tip to ensure the needle can be twisted and locked into place. A secure connection prevents accidental removal of the needle and injection of the medicine. This syringe type offers clear visual and audible confirmation of the locked position.

Eccentric tip are commonly used while administering medication parallel to the skin of a patient. Their main use is for aspiration of fluids. 

Catheter tip come with a tapered tip which forms a tight seal. These syringes are used for cleaning catheters, gastrostomy tubes, as well as other devices and used for wound irrigation.

Because syringes and needles work in partnership, it is essential to understand needle selection when purchasing online. The main factors to consider are the weight of the patient, the type of tissue and the medication to be injected. Shorter needles are used for subcutaneous injections, while longer ones are used for intramuscular injections. 

Understanding the structure and application of various syringes and needles will help you approach purchasing syringes and needles online with confidence and ease.
