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 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. The pressure in both occlusion cuff and
sensor cuff can be adjusted according to the size of the tail. If you need more
information, please e-mail your address and phone number, I will send you all
related information.
