Blood Banking Instrumentation Overview

Blood Banking Instrumentation

• Blood banking involves collecting, testing, and storing blood.
• A blood donor gives blood for transfusion.
• Blood transfusion is transferring blood or blood products from a donor to a recipient.
• The American Association of Blood Banks (AABB) was formed in 1947.
• AABB estimates 6.8 million volunteers donate blood annually.
• Approximately 13.6 million units of whole blood and red blood cells were donated in the US in 2013.
• A blood transfusion is needed every three minutes globally.
• One in ten hospital patients requires a blood transfusion.

Learning Objectives

• Define blood bank, blood transfusion, donor, recipient, and AABB.
• List instruments needed in a blood bank.
• Explain AABB standards for refrigerators, freezers, and ultra-deep freezers.
• Describe the functions of a blood monitor, plasma extractor, and platelet agitator.

Blood Bank Instrumentation Details

• Donation Chair: Used for blood collection.
• Blood Bags: Containers holding blood.
• Blood Collection Mixer: Mixes blood components.
• Tube Sealer: Seals blood bags for preventing leakage and hemolysis.
• Blood Bank Refrigerator: Stores blood at 1-8°C.
• Plasma Freezer: Stores plasma at -30°C.
• Platelet Agitator: A device for agitating platelet concentrates at 20-24°C.
• Plasma Extractor: Extracts plasma from blood.
• Plasma Thawing Water Bath: Used for thawing frozen plasma samples heated at 36 degrees Celsius.
• Refrigerated Centrifuge: Separates blood components (e.g. platelets, plasma, red blood cells) at 4°C.
• Blood Collection Monitor: A blood mixer for donation rooms and outdoor camps; ensures smooth mixing, volume accuracy, and precise monitoring of time and flow rate.
• Ultra-Low Freezer (ULT): Stores blood samples at -86°C for extended periods.

Additional Information

• The ideal temperature range for storing whole blood and most red blood cell components is 1°C to 6°C.
• The standard set point for blood bank refrigerators is 4°C.
• Plasma components must be stored at -18°C or below. The lifespan of plasma under these conditions is 12 months.
• Blood or blood component temperatures must be tracked continually and documented at least every 4 hours.
