Plastic syringe

Tip – needle attaches
Barrel – body of syringe
Plunger –part that fits into the barrel
Vary in size: 1 – 50 mL size capacity

62

Luer-Lok syringes

Locking device on the tip to hold needle firmly in place

63

Needle

Stainless steel

64

3 Components of needle

Hub
Cannula or shaft
Bevel

65

Part that attaches to the syringe

Hub

66

Length of metal part

Cannula or shaft

67

Sharp slanted tip of the needle

Bevel

68

Gauge

(viscosity of fluid determine size)
Thickness or diameter of the needle
14 to 28

69

Length (area for injection/condition of patient determine)

Measurement in inches of the shaft portion
½ to 4 ½ inches

70

The smaller the diameter of the shaft of the needle

the larger the gauge number will be.
25 gauge needle has a very small diameter
18 gauge needle has a large diameter

71

Which gauge is often used to draw a drug or solution into a syringe but seldom used to inject into the patient

18 gauge

72

Package labeled 20g/1 ½ indicates that

the needle is 20 gauge and 1 ½ inches long (length)

73

Bevel Varies from

long to short

74

subcutaneous & intramuscular injections

Long bevel

75

intravenous injections

Short bevel

76

Bevel always

up

77

Sealed glass container designed to hold a single dose
Intended for one use

Ampule Container

78

Small glass bottle with a sealed rubber cap and metal band; plastic cap
Different sizes; multiple doses within one

Vial container

79

Opening an Ambule

Hold upright and flick top with a finger until all the drug is in the bottom of the ambule
Gauze is wrapped around the indented neck and the top is snapped off
Discard any unused contrast

80

Opening A Vial

Remove plastic cap from top of vial
Determine amount to be withdrawn and draw up same amount of air into syringe
Attach needle to syringe

81

Insert needle into vial and inject air

Fluid will replace air in syringe
Place tip of needle above level of fluid before injection of air to prevent air bubbles in the solution

82

Vein Selection

Carefully assess area to determine best location for venipuncture

83

Things to consider for Vein Selection

Type of contrast
Length of procedure
Bolus or infusion
Age and physical condition of patient
Medical history

84

Never use .........for Vein Selection

the anterior wrist
Extreme pain and damage may result to radial nerve

85

Venipuncture Procedure

Retract and anchor vein distally with finger.
Hold needle @ a 20 to 30 degree angle with bevel up for proper insertion (hold the vein tie w/fingers)
Look for blood return in flashback chamber and advance catheter into vein (separate the needle ??
Secure catheter and release tourniquet
Connect syringe or tubing to catheter
