 BP-1

  

  Analogue single-channel transducer signal conditioner  

An analogue signal conditioner for monitoring pressure, force, temperature, and other physical parameters provided by transducers, BP-1 Pressure Monitor is designed to monitor animal arterial or venous blood pressure, displaying systolic, diastolic or average blood pressure. BP-1 accepts WPI's BLPR blood pressure transducer (page 82) as well as other BP transducers.

An audio monitor provides a signal with variable pitch and amplitude, allowing you to hear changes in blood pressure. Digital LCD display provides average or peak signal values from 0 to 1999 mV. When supplied with an optional pressure gauge, the LCD shows pressure in mm Hg. Recorder output connector allows direct connection to a pen recorder, oscilloscope or computer front end.

BLOOD PRESSURE

BLPR can be used for the direct arterial and venous pressure measurement in animal blood vessels. Supplied non-sterile, BLPR is accurate, linear and stable with temperature. May be sterilized cold with Cidex or a similar bactericide. BLPR is equipped with a twelve-foot cable and connector compatible with WPI's four-channel signal conditioning unit, TBM-4 Transbridge, and the single-channel BP-1 blood pressure monitor. Cable has moisture-resistant locking connector. A continuous, uniform lumen eliminates places for bubbles to form and lodge. The clear fluid path is easy to inspect. Easy to mount - slotted transducer body accepts Velcro strap. To facilitate setup and operation, a four-way stopcock that allows easy filling, flushing, and zeroing of the transducer is included. Typically, the stopcock is located between the transducer and the animal catheter where it can be used to quickly zero, flush, or de-bubble the transducer.
