The system requires warming of rats and mice. The rodents should be warmed to an ambient temperature of 30°C for rats and 32°C for mice. The cuff has a built-in photoelectric sensor and the amplifier has an artifact filter, which minimizes the breathing and movement artifacts, enabling the user to pick out the endpoints easily.
The output is analog. The instrument has separate outputs for single channel and dual channel (superimposed and split) recording. The typical pulse amplitude is 100 mV to 1 V. The pressure amplitude is adjustable from 1 to 5 volts at 300 mmHg. If systolic and heart rate are desired, a single channel chart recorder (No. 58805) is sufficient. If the Mean and Diastolic are the desired reading then a dual channel chart recorder is recommended (No. 58806) or the Chart Recorder software package (No. 58801).
Linear Deflation Kit
We strongly recommend using the Linear Deflation Kit with this system. It is unique in that the valve allows the user to deflate the cuff at a constant rate. The rate is adjustable by means of the control screw in the valve head using the supplied screwdriver.
The valve's construction is made so that upon stopping inflation the deflation starts immediately at the set rate.
The Linear Deflation Kit consists of: A manual bulb with special valve, one air ballast, T connectors and one screwdriver.
This single channel and dual channel recorders are ideal instruments for use in recording non-invasive blood pressure in laboratory animals. Chart Recorder Software converts BP outputs to digital data and replaces chart recorders.
The "Plot" and "Home" function can set the pen back to the start for comparative measurements. The pen starts from exactly the same point of the chart in a repetitive form.
The Manual Inflation BP monitor system comes complete with an amplifier, single channel chart recorder, a tail cuff and sensor to accommodate a 250g rat, restrainer, cables, sphygmomanometer and accessory package. We strongly recommend using the Linear Deflation Kit with this system.
