Non-Invasive Blood Pressure Monitor "Semi-Automatic"
|
- Ideal whenever smaller numbers of animals are to be measured
- Pressure in tail cuff is increased and decreased stepwise by the user
- The control unit is ready for connection to a chart recorder in order to display the pulsation
curve picked up by the sensor
- The systolic blood pressure values can then be easily read off from the calibrated pressure
waveform
- Available for a variety of laboratory animals
|
In the development of this non-invasive measuring system for determining the systolic blood pressure in
small laboratory animals the main aim was to be able to offer a small, favorably-priced and mobile
instrument.
It is based on the time-proven "Tail-Cuff Method" - this has been continually developed and improved by
our technicians for more than thirty years. Instead of the piezo-transducer used previously, a new
optical blood pressure sensor is used that allows reliable signal recognition even in very small
animals. In this way a technologically high-quality measuring system has been created; it can be
supplied for use with all small laboratory animals (mice, rats).
Non-Invasive Blood Pressure Monitoring System "Fully Automatic"
|
- MRI-compatible
- Warming up the animals can be done by using the measuring platform with integrated heating or
with the TSE Heating Box with built-in electronic temperature control and continuous fresh air
supply (for up to 6 animals)
- The pulse curves are output during measurement and pressure values are stored for subsequent
statistical analysis
- The system is also available in laptop configuration
|
For determining the systolic and diastolic blood pressure in a variety of laboratory animals (mice,
rats, dogs and others). Accurate and reliable determination of systolic, diastolic and mean pressure
value as well as heart rate is performed simultaneously in up to 72 channels facilitating rapid
screening of large animal populations.
Invasive Blood Pressure Monitoring System
|
- In the basic version it is configured with one pressure (sys, dia & mean aortal pressure or
LVP Min/LVP Max) and one rate display per channel
- It can be upgraded to calculate dpdt or extended with flow and ECG channels
- Real-time waveforms may also be incorporated to store signals with high resolution
|
This package is based on our versatile BioSys data acquisition software. It comes complete with one or
more blood pressure transducers or Millar tip catheters for arterial or left-ventricular pressure
measurements.
Telemetry
 |
- System for telemetric recording of physiological data such as the biopotentials ECG, EEG, EOG,
EMG, temperature and activity
- Can be used for the monitoring of conscious, freely moving laboratory animals - from small up
to large size
- Hardware components: transmitter, antenna with receiver and control unit for converting analog
signals to digital signals
- Software for recording and evaluating biosignals - with a special mode for fast signals in the
millisecond range
|
The system can be equipped with the transmitter for the required biosignals - different models with
different transmitter signal ranges are also available. Up to three animals can be placed per cage for
interaction measurements.
Special solutions to meet individual customer requirements are possible - e.g. telemetric measurements
while simultaneously recording the drinking & feeding behavior or the use of transmitters during
inhalation studies in a Whole Body Exposure Unit.

Drinking & Feeding.
Volume Meter
 |
This fully computerized volume meter allows the plethysmometric determination of rodent paw volume
(rats & mice). It is also suited for any other solid specimen. In the basic configuration volumes
up to 9.99 ml can be measured accurately and reproducibly.
The system provides a high precision sensor used to determine the change in level of a fluid column.
The measuring values are directly transferred into an Excel Sheet. |
Bronchospasm Measuring System
|
The bronchospasm measuring setup allows to easily determine changes in airway resistance of an
anaesthetized animal that is artificially ventilated at a fixed pump volume. Spasmodic or spasmolytic
effects of a test drug will induce variations in the so-called "respiratory overflow" that can be
measured as changes in air flow rate by a sensitive electronic air flow transducer.
After filtering and amplification the flow signal is output on a chart recorder. The drug induced
effect on ventilatory performance can be read off from the waveform amplitude. The system can also
be connected to a data acquisition system if
desired. |
