For most of us, when we think of a syringe, we think of a needle sticking out of a small plastic body but there’s a lot more to know about needles and syringes! Together, they are usually used either to inject medication into the body or withdraw some fluid from it. Not all syringes are the same and there are different requirements for different purposes.
Types of Syringe and Needles
Syringes come in a variety of designs and specifications. While some are disposable, there are also others with an attached needle or no needle at all. The right type of syringe is selected based on the exact requirement and the amount of medication that it needs to carry. On the other hand, needles are selected based on the length and size of gauge. The location of the body where the injection needs to be administered is the prime determinant of the gauge type and thickness of the needle. One of the most commonly used syringes is the U-100 insulin syringe, mostly used to administer diabetic medication. This type of syringe is only meant for single use and is thus, highly cost effective when coupled with the needle.
How to select the right syringe
To select the right syringe, the first question to be asked is the volume of medicine that needs to be administered and what the ideal pressure flow must be. Volumes are generally measured in centimeters or millimeters – both of which are considered equal in value. In other words, a 1 mm syringe carries the same volume as a 1 cc syringe. Naturally, higher volume of medicine requires a large syringe size while low-pressure flow works better with a relatively small size. Additionally, the purpose of the syringe is also extremely important – is it to be used for an injection, irrigation or medical tubing. One must keep these small details into consideration when making a medical equipment online purchase.
Selecting the right needle
Commonly used needle tips include the slip tip, eccentric tip, Luer lock and the catheter tip.
- A Luer Lock tip syringe is most widely used around the world, mostly because installing and removing the needle requires minimum time and effort. The needle comes with an easy twist mount that helps secure it onto the syringe and ensure better safety.
- The Luer lock needle can only be used with the barrel of a Luer lock syringe while the slip tip needle hub can be matched with all other types of syringes. The latter is designed to easily slip over the barrel’s tip and allow easy removal and installation.
- A slip tip syringe is another common variant that can be simply fit by pushing the needle hub on the syringe.
- A catheter slip tip is commonly used for medical tubing like feeding tubes or catheters.
- Eccentric tips are best fit when an injection needs to administered parallel to the patient’s skin. It is also advised in case medication needs to be injected into a vein on the surface of the skin, such that the needle penetrates both walls of the vein.
Needle thickness and length
Needles are categorized into different types based on their length and thickness. While short needles are mostly used to inject medication underneath the skin surface, long length needles are a better fit when the injection needs to reach the patient’s body muscles.
Thick gauges come with long needles and are used for patients with relatively thicker skin. Naturally, fine gauge needles are lesser painful. Another important consideration in picking the right needle is the medication’s viscosity. If the viscosity is thick, the gauge number should be lower. High viscosity medications would require a needle with a low gauge number or one with a wide width.
When buying syringes, it is extremely important to keep in mind your exact requirements. Only trust reputable online stores such as Smart Medical Buyer to buy syringes online. Additionally, follow this quick list to understand your specifications and shop accordingly:
- Volume of medicine determines the right size of the syringe
- Type of syringe hub is based on needle hub – Slip Tip, Luer Lock, Eccentric Tip or Catheter Tip
- Needle gauge and needle length vary with location of injection
- Viscosity of medication determines needle gauge
