2. • Medicine Taken into the body or administered in a manner oth
er than through the digestive tract, as by intravenous or intram
uscular injection.
• The term "Parenteral Devices" is used for the equipments
needed for the administration of parenteral drugs.

Introduction of parenteral

3. 3
Needs of parenteral
• Immediate therapeutic responses.
• Useful in non-cooperative patient.
• Accuracy of dose is achieved
• Therapeutic responses are more rapidly controlled.
• Immediate physiological action can be obtained.

4. 4
Different parental devices
• Syringes
• Needles
• Cannulae
• Catheter
• Infusion set
• Injection port

5. 5
Syringes
• A syringe is a simple reciprocating pump consisting of a plunger (though in
modern syringes it's actually a piston) that fits tightly within a cylindrical tube called
a barrel.
• Syringe sizes may vary from 0.25 ml to 450 ml, and can be made from glass or
assorted plastics.
• Types of syringe tips:
 Luer-lok tip.
 Luer-slip tip.
 Eccentric tip.
 Catheter tip.
• Examples: - medical syringe, insulin syringe, disposable syringe
& tuberculin syringe

6. 6
Needles
• Needles is a slender, sharply pointed instrument or devise used for suturing, ligaturing or
puncturing, removal of material from a clinically or radiologically identified mass by
aspirating it through hollow needle attached to a syringe.
• Made up of stainless steel or aluminium.
• Gauge: Diameter of opening use to designate six of lumen.
• Medical Use:7 to 33 where 7 is largest and 33 is smallest.
• Examples :Hypodermic needles, winged needles.

7. 7
Cannulae
• A cannulae is a tube that can be inserted into the body, often for the delivery or removal of fluid or for
the gathering of data.
• Cannulae normally come with a trocar attached, which allows puncturing of the body in order to get
into the intended space
• Its size mainly ranges from 14 to 24 gauge.
• Examples:- Intravenous (IV) cannulation & Nasal cannulation.
Catheter
• Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical
procedure.
• Catheters can be inserted into a body cavity, duct, or vessel. Functionally, they allow drainage,
administration of fluids or gases, access by surgical instruments,
• Examples: Balloon catheter.

8. 8
Infusion set
• The infusion set is most commonly used to administer fluids from an
intravenous container by gravity. The more basic sets are found to
contain a bottle or bag piercing pin, a sight chamber to allow the
counting of drops
• The stain less steel cannulas are used for I.V administration, an 18-21
gauge needle is commonly used.
Advantages:
 Provide accurate and timely delivery of fluids and drugs.
 Can change the flow rate when needed.

9. 9
Injection port
injection port is a medical device used for the administration of insulin or other
physician approved medicine into the subcutaneous tissue (the tissue layer just below the
skin).
The device is similar to infusion sets used by insulin pumps, except it is configured to
receive a syringe instead of a tubing system.
Immediately after insertion the needle is removed and the cannula remains below the
surface of the skin.
Advantages:
Reduces skin punctures
Reduces fear and anxiety associated with multiple daily.
Disadvantages:
Injection ports must be obtained in addition to syringes and medication.
