Physiobelt

The Physiobelt system is designed for long-term recording and transmission of an ECG signal with 500 Hz frequency via the radio channel and is used as part of a computer system that provides wireless reception of data and their processing in ECG researches of animals of the average and medium size (rabbits, guinea pigs, rats).

Key features and benefits of the system:

• 10 hours from a fully charged battery,
  more than 100 days in standby mode
• Transmission range - 10 meters
• Weight not more than 50 grams

The kit includes:

• Wireless amplifier Physioball
• The set of electrodes
• Radio module with USB interface
• Application software
• Vest for the animal

Areas of use:

• Testing of pharmaceuticals
• Training of students in courses of human and animal physiology
• Long-term monitoring of physiological parameters
• Veterinary Medicine

New features of the system:

• It is as easy as possible to work with the system because on the body of the amplifier there are no buttons more
• The amplifier can be recharged by wireless charging (a wireless charger is purchased separately), the amplifier recharges via a USB cable
• The amplifier allows you to use more channels of registration (optional)
• Ability to change the sampling frequency, reducing the number of used channels: thus it is possible to register up to 8 channels with a frequency of 120 Hz and one channel with a maximum frequency of 946 Hz, also, there are intermediate values of frequencies for each selected number of leads
• The software allows to analyze heart rate (R-R intervals) of the animal in real time and keep the values of R-R intervals in textual or tabular (Excel) file
