About RatPaak™
The RatPaak™incorporates state-of-the-art wireless technology for viewing and recording physiological
signals such as electroencephalogram (EEG), electromyogram (EMG), electrocardiogram (ECG), or
electroculogram (EOG), in small laboratory animals, weighing 100 grams or more.
This two-channel general purpose signal monitor is the most unobtrusive, flexible, and convenient way of
measuring and transmitting physiological signals. Subjects can now be untethered. This allows behaviors
such as feeding, nesting, sleeping, and sexual activity to be observed without having the animal wired to a
cage. The remote monitoring and real-time data viewing capabilities of the RatPaak™ offer new
opportunities for researchers and scientists in the wireless monitoring of lab animals.
The RatPaak™ wireless physiological signal monitor consists of a Transmitter, a Receiver Assembly (the
receiver, receiver cable, and power supply), accessories (mounting band, screwdriver, batteries, and
harness), and a PC Operator Interface Software program. The integrated transmitter is compact enough that
it can fit comfortably on rats and other small animals without impeding their activities. The RatPaak™
transmitter weighs about one-quarter of an ounce and can transmit signals to a nearby receiver up to a
distance of 50 feet.
The RatPaak™ collects signals from wires attached to the subject, performs analog-to-digital conversion,
encoding, formatting, and transmitting of all signals. The signals are communicated using a 902-928 MHz
radio transmitter. Over one hundred transmitters can be used in the same area without interference with
one another. The Receiver Assembly receives the transmitted data packets, performs extensive error
detection and correction, and then sends the data through a Receiver cable to the PC Operator interface
where data can be stored, monitored in real time, or analyzed at a later time.
The RatPaak™ Capture program consists of several software components which allow the user to acquire,
store, view, and export physiological data as acquired by the RatPaak™ Transmitter. The software
provides a simple graphical interface for setting up and controlling data acquisition. In addition, several
functions are available to allow data acquired from the RatPaak™ Transmitter to be used in other software
applications, such as Matlab
®
, LabView
™
, and Excel. Programmability at the time of manufacture allows
various applications to be integrated into one system, allowing Cleveland Medical Devices to customize the
number of input channels, sampling rates, filters, gains and RF frequencies according to your research
needs.(is this correct?) As a flexible research tool by design, the RatPaak™ offers a new, low cost
monitoring solution for unrestrained animals, simplifying traditional monitoring applications.
This device is not FDA approved to market and is available for non-medical use only unless it is to be
used in an IRB approved program
