Lab 5 Syringes & Needles

Anatomy of a Syringe with Needle

• Common Needle & Syringe Sizes

Syringes:

• 1 cc (TB)

• 3 cc

• 6 cc

• 12 cc

• 20 cc

• 35 cc

• 60 cc

  Needles:

• 14 gauge

• 16 g

• 18 g

• 20 g

• 22 g

• 25 g

• 27 g

Lower the number the thicker diameter needle

Syringes

• 1st (left): 3cc

• 2nd: 6cc

• 3rd: curved tip

• 4th: 60cc

Catheter Tips

TB Syringe (1cc) Tuberculin Syringe

• 1mL total volume

• Largest increments are 1/10th of mL (0.1)

• Smallest increments are 1/100th of mL (0.01)

TB Syringe continued..

• Watch the hub for bubbles

• Can “tap” to help remove air trapped in liquid

• Need to be very careful about bubbles in liquid because they can greatly alter the amount of actual medication given to small animals

• Values of Lines on Different Syringes

• Each line for: 1 cc TB syringe: Between 0.1 cc and 0.2 cc = 0.01 cc = 1/100 cc

• Each line for: 1cc syringe 0.02 cc = 2/100 cc

• Each line for: 3cc syringe 0.1 cc 1/10 cc

• Each line for: 6 cc & 12 cc = 0.2 cc = 2/10 cc

• Each line for: 20 cc each line = 1cc

Needles

22 gauge:

• Very commonly used in small animal medicine

• Different lengths

25 gauge:

• Very commonly used in small animal medicine

27 gauge - tiny

• TB size

Insulin Needles and Syringes

• 28-30 gauge needle attached to end of syringe, cannot detach

• Units of insulin, increments of cc’s on barrel of syringe

• U40 or U100

  • Use only insulin in U40

• 10 units = 0.1 cc

Needle and Syringe Use

• Administer injection of a sterile fluid (medication, vaccine, etc.)

• Venipuncture and blood collection

• Needles get dull easily, particularly the smaller gauge

• Need to keep sterile prior to injecting pet

  • No fingers on needle

• Prior to SQ or IM injection into pet, aspirate to make sure do not get blood

  • When giving vaccines pull back to make sure you’re not in a vein or artery

• Dispose of needle in sharps container

Sharps Container

In veterinary medicine, non-infectious (to humans) blood tainted syringes do not need to go into sharps container, but needles do go into sharps container

Syringe Use

“No darts” no “cigarettes”

A syringe is a one handed instrument
