We have recently developed a 8 channel noninvasive blood pressure(NIBP)
monitoring device that is controlled by microprocessor and has WindowsTM
application program. This newly invented system can measure systolic, diastolic
and mean pressure along with heart rate in both rats and mice. It uses two tail
cuffs: occlusion cuff and sensor cuff. The occlusion cuff is used to occlude
the caudal artery of tail in animals while the sensor cuff, positioned behind
the occlusion cuff is used to detect the pulsation of the artery. The system
has an associated restrainer (variable sizes) and heating compartment that
heats the animals tail and thereby maintain blood flow through the tail without
affecting the animals body temperature.  If you are interested, please send
your address, I will mail you all necessary information.
