2. Introduction Parenteral product are medication or other preparation intended for adminstration by injection, either through the skin or gastrointestinal tract(GI) tract. Parenteral adminstration allows the active ingrediant to be delivered to an organ, a lesion, a muscle, a nerve or another body tissues. In addition to medication, fluids, electrolytes and nutrients may be adminstered parenterally .

3. Introduction to Needle A hypodermic needle, one of the category of medical tools which enter the skin, called sharps is a very thin, hollow tube with one sharp tip. It is commonly used with a syringe. A hypodermic needle is used for rapid delivery of liquids, or when the injected substance cannot be ingested, either because it would harm the liver. It is also useful to deliver certain medications that cannot be delivered orally due to vomiting.

5. Anatomy of Needle Needle Gauge Refer to the diameter of the needle The Point The Sharp end of the needle

6. Anatomy of Needle The Bevel The bevel is the flat, slanted surface near the point. The Lumen The hollow core of the needle that form an oval shaped opening at the beveled point.

7. Anatomy of Needle The Shaft The hollow steele tube that runs the entire length of the needle. The Hub The end of the needle that attaches the syringe

8. Size of the needle with colour code.

9. Penetration Point In the Body. Intravenous Drugs can be administered into almost any part of the body, including a vein Intramuscular IM injection are administered deep into skeletal muscle.

10. Penetration Point In the Body. Deltoid The common location are usually the deltoid(Upper arm). Dorsogluteal (Back Hip) Another common injection location is the back hip

11. Penetration Point In the Body. Subcutaneous The SubQ route of administration is used for small volumes of medication Intramedal ID injection are administered into the vascular layer of the skin between the dermis and epidermis

16. Syringe A syringe is a single pump consisting of a plunger that fits tightly in a tube to assist the liquid or solids into an object either to through a needle, tubing The most common use of syringe is to administer injections into the body.

17. Syringe A syringe consists of barrel , plunger and a tip

18. Anatomy of Syringe

19. Information about Syringe Parts. Barrel A hollow cyclinder that holds the medication. It has calibration on the outer surface.

20. Information about Syringe Parts. Plunger Fits in the barrel and is moved back and forth. Pulling back on the plunger draws the medication or air into the syringe. Pushing in the plunger forces air or medication out of the syringe.

21. Information about Syringe Parts. Tip The end of the syringe that holds the needle.

22. Types of Syringes Hypodermic Syringe Hypodermic Syringe are caliberated in cubic centimeters (cc) or mili -litres( mL ) or units. Practitioner often refer to syringes by the volume of cubic centimeter they contain for example 3cc syringe Although many syringe are still labeled in cubic centimeters , manufacturers are now phasing in syringes labeled in milimeters . The smaller capacity syringes are used most often for subcutaneous or intramuscular injection of medication. The larger size are commonly used to draw blood or intravenous administration Syringe 20mL and larger are used to inject volumes of sterile solution.

23. Types of Syringes Tuberculin Syringe The 1mL of syringe, also called tubeculin syringe, caliberated in hundreds of milimeters . Because there are 100 of lines each line represents 0.01 mL The syringe is used for intradermal injection of very small amounts of substance in test for tuberculosis and allergies The tuberculin syringe is the preferred syringe for use in medication less than 1mL.

24. Types of Syringes Insulin Syringes. It used for the subcutaneous injection of insulin and are caliberated in units rather than milimeters . The most commonly prepared concentration of insulin is 100 units per milliliter 100 units= 1ml

25. Types of Syringes A prefilled syringe. A prefilled, single dosed syringe contain the usual dose of a medication Some prefilled glass cartridges are available for a use with a special plunger called a tubex If the medication order is for the exact amount of drug in the prefilled syringe, the possibility of a measurement error by the person admiring the drug is decreased.

26. Types of Syringes Safety Syringes. In order to prevent the transmission of blood borne infections from contaminated needles, many syringes are now manufactured with various types of safety devices. For example a syringe may contain a protective sheath that can be used to protect the needle sterility. The sheath is then pulled forward and locked into the place to provide a permanent needle shield for disposal following injection Other may have a needle that automatically retracts into the barrel after injection
