DR-II Auto-Blood Sampling

DR-II is a system for automated blood sampling from
laboratory animals with previously implanted catheters. This
system not only minimizes researchers’ work load but also
reduces the stress on the animals.

Prior to sampling, unused blood is aspirated
from animal to inserted an air gap.


Sample blood is aspirated and sandwiched by
air gaps.


The blood is collected via by a fraction collector.
The unused blood is returned to the animal

Parameter setting
Sampling parameters (kinds of animals, intervals, volume, administration conditions*,etc.) are set for each channel independently or collectively. Irregular sampling setting is
also available.

 

Operation
Each channel is controllable independently. Group of channles

are also controllable simultaneously by channel grouping.

 

Monitoring
Sampling history, status and end time for each channel can

be monitored.

 

Recording

Every sampling time, its status and administration time*

for each channel are recorded. These data can be exported
to other softwares.

Even if the PC freezes or is shut down, the parameters are

stored in the sampling unit and blood sampling isn’t interrupted.
(The sampling unit is equipped with Start/Stop button.)

 

* For administration, a syringe pump,

two way swivel, etc. are required.

Major Features


Any sampling interval or volume is programmable by users and this

makes irregular time setting possible. Timer function is also equipped.

Sample blood is sandwitched by air gaps. This prevents sample dilution

as minimum as possible and eliminates any cross contamination. For a

precise sampling, volume of catheter and tubing are taken account of.

Blood sampling from freely moving animals is possible. Optical senser

makes sampling volume control more precise than usual. The volume of catheter is measured and calibration with this volume is carried out automatically. At most 16 units of the DR-II can be controlled simultaneously
or independently by one PC (One DR-II carries out sampling from one catheter).
