• BLOOD DRAWING STATION


  • Primarily used for outpatient department.
  • It has table for supplies, chair, & a bed/padded table.
• PHLEBOTOMY CHAIR


  • comfortable w/an adjustable arm rest.
• EQUIPMENT CARRIER


  • makes collection portable.
• NEW PAIR OF GLOVES AND GLOVE LINERS


  • used for performing blood collection.
• WHAT GLOVES ARE ALLOWED/USED IN VENIPUNCTURE?

  • non sterile
  • disposable latex
  • nitrile
  • neoprene
  • polyethylene
  • vinyl
• ANTISEPTICS


  • used to prevent sepsis. (harmful bacteria that enters human body through the wounds)
• DISINFECTANTS


  • used in killing microorganisms on surfaces & instruments
• HAND SANITIZER & WALL MOUNTED HAND SANITIZER DISPENSER


  • substitute for hand washing w/ exception of visibly soiled hands.
• GAUZE PADS


  • are clean 2x2 inch gauzed folded in fourths.
  • used to hold pressure after blood collect and used instead of cotton balls & are fluid proof. (prevent contamination)
• BANDAGES


  • can be used on the blood collection site once the bleeding stop.
• 1x3 INCHES GLASS MICROSCOPE SLIDES FOR BLOOD FILMS


  • used in hematology determinations.
• PEN WITH NON SMEAR INK


  • used for labeling specimens
• WATCH WITH TIMER


  • determining collection times and to time tests
• NEEDLE AND SHARP DISPOSAL/CONTAINERS


  • known as sharp containers
  • used as receptable for needles, lancets, & other sharp objects.
• BIOHAZARD BAGS


  • used to transport blood & other specimen.
  • they are leak proof bags marked w/biohazard logo.

   
• BLACK


  Non-infectious dry waste
• GREEN


  Non-infectious wet waste
• YELLOW


  Infectious & pathologic waste
• YELLOW W/ BLACK BAND


  Chemical waste w/ heavy metals
• ORANGE


  Radioactive waste
• RED


  Sharps and pressurized containers
• VENIPUNCTURE EQUIPMENT

  • VEIN-LOCATING DEVICES
  • TORNIQUET
  • NEEDLES
  • NEEDLE GAUGE
  • EVACUATED TUBE SYSTEM (ETS)
• VEIN LOCATING DEVICES


  • transillumination portable devices
  • uses infrared light to locate & assess veins
• TORNIQUET


  • constricting device applied to patient's arm
  • it restricts venous blood for a period of time.
• NEEDLES


  • used to withdrawing blood sample.
  • these are sterile and for single use only.
• 3 TYPES OF NEEDLE

  1. multi-sample
  2. hypodermic
  3. winged infusion
• NEEDLE GAUGE


  • classified according to the diameter of lumen.
  • higher gauge number = smaller the actual needle diameter
• WHAT IS THE APPROPRIATE GAUGE?

  • 20-23
• WHAT IS THE COMMON/IDEAL GAUGE?

  21
• EVACUATED TUBE SYSTEM (ETS)


  • closed collection system composed of multi-sample needle, tube holder, and evacuated tubes.
  • it prevents exposure to contaminants.
  • allows numerous tubes to be collected in a single venipuncture.
• WHAT IS THE RELATIONSHIP OF GAUGE & NEEDLE NUMBER?

  The relationship of the gauge number of needles to the diameter of the needle is inversely proportional.
• LENGTH OF THE NEEDLE USED IN VENIPUNCTURE?

  1-1.5 INCHES
• WHAT IS THE DIFFERENCE OF ANTISEPTIC & DISINFECTANT?

  • ANTISEPTIC- disinfect the skin
  • DISINFECTANT- disinfect the surface
• ANTISEPTIC USED IN VENIPUNCTURE?

  • 70% ethyl alcohol
  • 70% isopropyl alcohol,
  • Benzalkonium chloride,
  • Chlorhexidine gluconate
  • Hydrogen peroxide
  • Povidone-iodine and tincture iodine
• DILUTION OF DISINFECTANT

  • Environmental Protection Agency (EPA)- registered sodium hypochlorite with 1:100 dilution.
  • 1:100 1mL of household bleach to 100mL distilled water
  • 1:10 1mL of household bleach to 10mL distilled water (spill)
• HOW MANY DILUTION USED IN SPILLS?

  1:10 dilution is used
• 3 TYPES OF PHLEBOTOMY NEEDLES

  • Multi-sample
  • Hypodermic (Syringe)
  • Winged Infusion (Butterfly)
• SYRINGE SYSTEM


  used as an alternative method when drawing blood from patients with small or difficult veins.
