System (DBRS) facilitates refusion of erythrocyte
concentrates while wound drainage is ongoing.
This procedure is employed in the first 6 hours
- Place the drain I with the DRAINTEC®-Spear
with no risk of contamination (see leaflet).
- Activate the device. Based on the
inserted DBRS disposable material, the device
identifies the operation mode and switches to WD
(wound drainage mode).
- Activate the addition of additives on button area
A+ and select the desired ratio of drainage-versus
- The additives (sedimentation
accelerating agent) are infused through the
second infusion tube II.
- Both drainage and additive fluids are guided by
the change-over clamp H to the instillation
chamber J, and the dosage is controlled by
optical-electronic drop counting.
- The peristaltic roller pump D draws in the blood mixture.
- The blood mixture is then directed to the
sedimentation bag K, where the erythrocytes
separate from the plasma by sedimenting.
- The erythrocyte concentrate is drained into the
refusion bag L and can be retransfused to the
Wound drainage is conducted according to the
Wound Drainage procedure described above.
Therefore wound drainage never is interrupted,
also during refusion!!
Properly operated, DRAINTEC®
Drainage-Blood Refusion ensures:
- 80-85% erythrocyte concentrate
- no risk of contamination
- minimisation of the risk of contamination by HIV, hepatitis, etc.
- cost reduction (regards donor blood and staff costs)
