Instructions for use of Bloodloc™ Safety System

Procedures for Phlebotomists
Please note that patients are wearing a wristband with a three-letter Bloodloc™ code. This code is unique to each patient for the length of the hospital stay. Should the patient be readmitted, a new wristband with a new Bloodloc™ code will be issued. There are over 12,000 codes, and wrist TABS will be color-coded in batches to ensure that there are never any duplications in the hospital at any time.

After drawing a specimen for type and cross, the three-letter Bloodloc™ code is transcribed from wristband to specimen tube. Care should be taken to print the code in capital letters and circle it so that there is no confusion with the phlebotomist's personal initials.

The Blood Bank will accept only specimens so coded. In the event a specimen is received by the Blood Bank without an identifying three-letter Bloodloc™ code, the specimen will be rendered invalid and will be discarded. A fresh sample will be requested.

Procedures for Blood Bank personnel
When specimens are received by the Blood Bank they will have, in addition to the phlebotomist's initials, an identifying three-letter Bloodloc™ code, printed in capital letters and circled. Specimens without this code will be rendered invalid and discarded. A request would then be made for a fresh sample to be drawn and identified correctly.


The Bloodloc™ code is to be entered into the patient's current Blood Bank records where it should be readily accessible to a technician locking up blood. The following steps are then taken when the blood is ready for dispensing.
  • Three-letter Bloodloc™ code is obtained from patients Blood Bank records for current admission.
  • Bloodloc™ is set by lining up three-letter Bloodloc™ code from left to right, turning each dial CLOCKWISE, aligning with arrow marked CODE.
  • Lock is placed on level surface and all three dials are engaged by pressing down firmly with palm of hand on center. A plastic ring will separate from the bottom and is discarded. Bloodloc™ is not set permanently at this code.
  • Matched and typed packed red cells are placed into the provided outer plastic bag.
  • Back of lock is inserted through hole in bag and front section is pressed firmly together. Dials are scrambled by turning in either direction. Blood is now ready for dispensing.

Procedures for Nurses
Please note that patient's now wear the customary hospital wristband to which has been added a three-letter code. This code is unique to each patient for the length of the hospital stay. Should the patient be readmitted, a new wristband with a new code will be issued. There are over 12,000 codes, which will be color coded in batches to ensure that there are never any duplications in the hospital at any time.

When packed red cells are delivered to the floor, the usual checks are performed to correctly identify the patient.

The RBC units will be issued locked up in an outer plastic bag. In order to unlock the blood the following steps must be taken:

  • Three-letter Bloodloc™ code is read from patient's wristband.
  • Bloodloc™ dials are turned in either direction to align the patient's Bloodloc™ code letters from left to right with the arrow marked CODE.
  • Pull Bloodloc™ apart. If the lock does not open easily, recheck the code. If lock remains closed, assume there is an error and call the Blood Bank.
  • On removal of the unit of blood, discard the lock and bag.

We suggest eliminating the second person needed to check the wristband, blood unit and accompanying compatibility documents since the Bloodloc™ system is a secure system - if the Bloodloc™ will not open, it's a case of wrong blood or wrong patient.
