Thus, the outer diameter of a catheter in millimeters can be calculated by dividing the French size by 3. [2] For example, a catheter with a French size of 9 would have an outer diameter of approximately 3.07 mm. While the French scale aligns closely with the metric system, it introduces redundancy and the potential for rounding errors.
The Birmingham gauge ranges from 5/0 or 00000, the lowest gauge number corresponding to the largest size of 0.500 inches (12.7 mm), to 36, the highest gauge number corresponding to the smallest size of 0.004 inches (0.10 mm). The increments between gauge sizes are not linear and vary. [2]
As opposed to low dead space syringes, high dead space syringes are conventional needle and syringe designs. The term "high dead space" refers to the fluid remaining within the needle and between the syringe hub and the plunger. This space can be as high as 84 micro liters in conventional syringes. [2]
Oral syringes are available in various sizes, from 1–10 mL and larger. An oral syringe is typically purple in colour to distinguish it from a standard injection syringe with a luer tip. [24] The sizes most commonly used are 1 mL, 2.5 mL, 3 mL, 5 mL and 10 mL. [25]
A syringe with a male luer lock fitting, and a needle with female luer lock fitting (purple) which screws into it. The Luer taper is a standardized system of small-scale fluid fittings used for making leak-free connections between a male-taper fitting and its mating female part on medical and laboratory instruments, including hypodermic syringe tips and needles or stopcocks and needles.
Equipment include syringes calibrated in tenths and hundredths of a milliliter. The dosage given is usually less than 0.5 mL, less than given subcutaneously or intramuscularly. A 1 ⁄ 4-to-1 ⁄ 2-inch-long (6 to 13 mm) and 26 or 27 gauge thick hypodermic needle is used. [1]

The needle on a safety syringe can be detachable or permanently attached. On some models, a sheath is placed over the needle, whereas in others the needle retracts into the barrel. Safety needles [1] serve the same functions as safety syringes, but the protective mechanism is a part of the needle rather than the syringe. Legislation requiring ...
