5-2. Operating Procedures
(1) Set target collection volume with the [PRESET]-[UP]-[DOWN] buttons.
(2) Place blood collection bag on tray.
(3) Route blood collection bag tubing through tube clamp.
[Note 3] The tubing length from the clamping point to the blood bag should not
be shorter than 30 centimeters (1 ft) to ensure proper rocking movement.
(4) Press [CLAMP] button to close tube clamp.
(5) Prepare phlebotomy site and stick donor.
(6) Press [
START
] button.
* Tube clamp is opened and the blood begins to flow into blood bag.
* Tray starts rocking.
* [BLEED] indicator is on.
* [ML] appears to indicate the number displayed is ‘net’ volume of
blood collected in blood collection bag, represented in milliliters.
[Note 4] Weight of blood bags and anti-coagulant, and any weights put on
tray are tared when [START] is pressed. All tared weights must remain
on the tray until the collection cycle ends. If any weights are removed,
blood volume will have an error of an equal amount.
[Note 5] Do not touch the tray or blood collection bags during the collection.
If the tray is pushed down, sensed weight may exceed the preset target
volume, then the clamp will close. When this happens, press [CLAMP]
button to re-open the clamp and continue collection. DO NOT press
[END] button, as it will clear the volume previously collected.
[Note 6] When the collected blood volume reaches 20 ml below the preset
target volume, the tray stops rocking until the preset target volume is
reached. This process assures accurate collection with a 1-2 ml tolerance.
For example, if the target volume is set at 500 ml, the tray stops rocking
at 480 ml and resumes rocking when the tubing is clamped at 500ml.
