• The Blood Collection Mixer CM735 provides efficient mixing of the blood with the
anticoagulant in the blood bags.
• It is a lightweight mobile unit with maximum portability.
• The panel display indicates the net volume of blood collected in the blood bag. It
automatically closes the tube clamp when the collected volume reaches the preset
selected figure. The display shows the total weight on the tray at the end of the
donation and elapsed collection time.
• Various audible and visual alarms are provided to ensure accurate and safe collection
and mixing.
The mixing motion is controlled by a microcomputer. When the blood collection is
started, the tray rocks for 3 cycles and pauses for 2 seconds, then resumes rocking. As
the collection approaches the preset donation amount, the tray stops rocking to ensure an
accurate donation. When the preset amount is reached, the clamp closes and tray resumes
rocking.
The Blood Collection Mixer monitors blood flow rate during the collection and donation
draw time. When the draw is less than 30 ml/minutes, the machine will alarm. The alarm
is both audible and visual. The alarm repeats every 60 seconds if blood flow remains low.
The LCD panel displays pertinent information.
The following information can be viewed on the LCD:
- total weight [gram] of blood and blood bags
- collected volume [ml] of blood
- target volume to collect [ml]
- elapsed time [min : sec]
- low battery voltage condition
- unit of displayed figure ([ml] or [gram])
- alarming condition
The unit can be powered by either a battery pack or an AC power adaptor.
A Nickel-Cadmium battery pack of 12 Volts/2AH capacity is used. It is replaceable and
rechargeable. An audible alarm sounds when battery voltage drops to its lower limit.
The battery can be recharged while in the mixer or with a separate battery charger unit.
The battery can be recharged while the mixer is in use if the AC power adaptor is
attached at rear panel jack of main unit. The battery can also be recharged by removing it
from the mixer and connecting it to a separate battery charger unit.

(A large battery charger, model BC162, which charges 6 battery packs same time, is
available for purchase from your distributor. With this charger, one pack among 6 is
recharged fast in 3 hours, and other 5 packs in 10 hours.)
It takes about 10 hours to recharge a pack from exhausted level to fully charged level.
A fully charged battery will operate the mixer continuously for approximately 8 hours.
The blood collection mixer unit can also be powered directly by using the AC power
adaptor. When both a battery pack and a power adaptor are connected at the same time,
the power adaptor supplies operating power and the battery is under recharging.
The tube clamp module can be positioned on either the left side or the right side of the
tray. It can easily be remounted on either side of the tray by the user.
The equipment is stored in a soft carrying bag, and weighs less than 4 kilograms.
When the power switch is turned on, the machine requires 30 seconds to stabilize
weight-sensing circuits. During this time the display shows a 30-second count down.
