Telemetry – used to monitor temperature,

gross motor activity and heart rate data.

Physiological and behavioral monitoring oftransgenic mice and other laboratory animals has never been simpler. Through the use of biotelemetry and a variety of available sensors, it is possible for VitalView to monitor up to seven different physiological or behavioral parameters from a single laboratory subject.

With VitalView software you can view incoming data and process and export ASCII data to your favorite analytical software package.

Combinations of the following parameters may be monitored for multiple laboratory subjects using VitalView:

  • Body Core Temperature
  • Heart Rate
  • Gross Motor Activity
  • Running Wheel Turns
  • Drinking/Licking Frequency
  • Feeding Behavior
  • Ambient Temperature
  • Ambient Light

VitalView Series 3000 and 4000

The VitalView system is made up of a series of components that work together to monitor a wide variety of sensors: VitalView Series 3000 and Series 4000. These sensors are assigned to one of these two series by the input device they require.

VitalView Series 3000 components use parallel data inputs that must be routed through a DP-24 DataPort to the PC. Each DP-24 DataPort is capable of accepting 24 channels of incoming data. Up to 10 DP-24 DataPorts may be combined in one VitalView System.

VitalView Series 4000 components use serial data inputs that must be routed through the serial port on your PC. Up to 32 receivers and 96 channels of incoming data may be received in this fashion.

Vitalview Series 4000 System

New Addition to the G2 Family!!
Due to the popularity of our G2 E-Mitter, released a year ago, our engineers have developed a G2 Heart Rate (HR) E-Mitter that is nearly half the size (by volume) of the original (Standard) HR E-Mitter. Ideal for use in mice, the new G2 HR E-Mitter uses the same ER-4000 Energizer/Receiver and VitalView data acquisition components as all other E-Mitters.

Standard E-Mitters and G2 E-Mitters monitor temperature and gross motor activity. Heart Rate E-Mitters monitor heart rate, temperature, and gross motor activity.

ER-4000 Energizer Receiver

No batteries are required to operate this revolutionary system. These special transponders (E-Mitters) allow you to forget about batteries and the recalibration necessary after battery changes. By allowing you to dispense with the time and money required for refurbishment and recalibration, they increase your productivity and allow you to follow animal care and use protocols more closely.

Temperature Monitoring

Mini Mitter has been the source for small animal temperature telemetry for over 30 years. With our Series 4000 E-Mitters, monitoring body core temperature can be performed with a minimum of effort. These temperature sensitive devices alter their pulse rate in response to temperature changes. The VitalView system records the average rate and converts this to temperature using temperature calibration values specific to each unit.

Activity Monitoring

The Gross Motor Activity Measure provides a basic index of movement for subjects implanted with an E-Mitter. As the subject moves, movement of the implanted E-Mitter results in subtle changes in the transmitted signal. These small changes are detected by an ER-4000 Receiver via telemetry and noted as activity counts. VitalView records these counts to produce a longitudinal record of m, ovement.

Circardian rhythms analyses recently got better! Due to your requests, VitalView 4.1 software now includes an additional filter that gives you a clearer view of ER-4000 activity rhythms. Click on the examples below to see the difference!

Heart Rate Monitoring (only available with Standard and G2 HR E-Mitters)

VitalView can record Heart Rate information reported in Beats Per Minute using the PDT-4000 HR and G2 HR E-Mitters. Heart Rate is determined by recognition of the electrical signals that stimulate the heart muscle to contract. These signals are processed and interpreted by the E-Mitter. The results are transmitted to the ER-4000 Energizer Receiver via telemetry.

Behavioral Monitoring

VitalView is capable of monitoring input from lab animals using several types of switch closure sensors. These types of sensors are commonly used for recording subject behaviors simultaneously with temperature, gross motor activity and heart rate recordings.

These types of behaviors can be monitored with VitalView:

Some sensors will require special caging arrangements.

Behavioral monitoring is accomplished using Series 3000 data inputs through a DP-24 DataPort. Each DataPort is capable of accepting 24 channels of incoming data. Up to 10 DP-24 DataPorts may be combined in one VitalView System.

Series 3000 and 4000 components may be used in the same VitalView system.

For a diagram of how these components may be assembled to form a system capable of meeting your needs, please download a VitalView brochure or fill out our information request form and we will send one to you.


Running Wheel Turns

Running Wheel Turns are recorded using a Magnetic Switch. The switch itself is mounted to the support frame of the running wheel. A magnet is attached to the wheel itself. As the wheel turns, the switch silently counts the number of times it is passed by the magnet.

Running wheel turns may be recorded using our new Mini Mitter Running Wheels or Nalgene Running Wheels.

Drinking/Licking Frequency

Lick Sensing is an index of drinking behavior. It is accomplished by counting the number of times that the subject touches the water bottle nipple. This is accomplished whenever the subject completes a very low current electrical circuit between the water bottle nipple and a metal floor plate or wire grid floor.

The Mini Mitter lick sensor is a complete solution for this type of monitoring. It includes the floor plate, mounting brackets, water bottle and the special non-conductive coverings required for successful use. It is necessary to make a small modification to animal domicile cages in order to mount the lick sensor floor plate. 100 and 250 ml water bottles are available.


Feeding Behavior

Our Infrared Feeding Monitors are positioned over a Nalgene Feeding Assembly so whenever the subject moves to feed, an infrared beam is broken. The number of times that this beam is broken provides feeding frequency information while the period of time that the beam is broken provides feeding bout duration information. This combination provides an index of feeding behavior.

Infrared feeding monitors are designed for use with Nalgene Feeding Assemblies. These assemblies come as a standard part of Nalgene Metabolic Cages or may be fit to Customized Nalgene Domicile Cages.

Mini Mitter Running Wheels

This 11.5 cm (4.5 inch) diameter wheel is inexpensive and durable. It is constructed entirely of stainless steel support system components: wheel, frame, axles, collars, fasteners, and clips. The new design uses bronze bushings for low friction and squeak-free.

A unique magnetic switch counts turns and slides into a spring clip for easy assembly and dissassembly making cage changes and cage washing simple and effortless. A glass tube protects the components from gnawing teeth for worry free recordings.

Mini Mitter Running Wheel Features

  • Designed to be fully contained within your standard home cage
  • Hangs from most any wire grid lid
  • Accurately counts wheel turns from voluntary wheel running
  • Fully compatible with our VitalView data acquisition system and ER4000 transponders
  • Simple and easy to use
  • Tool-free assembly and disassembly
