small animal tail noninvasive blood pressure monitor
Part #: NIBP250

The NIBP250 small animal tail noninvasive blood pressure monitor is a stand-alone device to measure the blood pressure of small animals and has a touch screen LCD user interface to control the system and display the data. The monitor does not require a data acquisition system or computer to analyze the data, but can interface with existing BIOPAC data acquisition platforms and third-party systems when combining other physiological signals. The NIBP250 is completely stand-alone; displaying, analyzing and saving the data for further use.

With a different Platform



The NIBP250 incorporates a built-in pump that automatically inflates the blood pressure cuff to occlude the vessel in the tail of a rat or similar small animal. Once the pump reaches the inflation point it slowly deflates the cuff, providing a linear drop in pressure.

A touchscreen LCD monitors the pressure and pulse signals. Use the simple touchscreen interface (or connect a USB mouse if preferred) to easily mark the points where systolic and diastolic blood pressure appear. The system uses a peak detection routine that locates the peak of each of the pressure pulses and marks it with an asterisk. The cursors jumps from peak to peak and provides instantaneous readings for systolic and diastolic blood pressure. The NIBP250 displays the marked values for the systolic and the diastolic blood pressures and the calculated values for the mean blood pressure and the heart rate in the results window. The values are also displayed adjacent to the cursors.

The maximum inflation point can be adjusted in the properties window. The NIBP250 also includes pressure calibration and validation tools to be able to refresh and check the factory calibration. The cuff assembly attaches to the equipment via a Luer lock connector and the pulse sensor attaches via a BNC connector. The equipment also has a gain adjustment control to amplify or attenuate the pulse signal. NIBP250 provides two analog outputs for uncalibrated pressure and pulse waveforms.

The NIBP250 module has a USB 1.1 compatible flash memory port and SD card slot to move data to a computer for further analysis and publishing. It reports the raw and analyzed data files in ascii format which can easily be imported into your favorite application (e.g. AcqKnowledge, Excel, SPSS, MATLAB, etc.).
