Ideal loggers for biomedical studies

The Star-Oddi loggers are small implantable recorders that measure heart rate and/or temperature with high accuracy and provide real time telemetry with live data to a PC or logging, where real-time data is stored in their internal memory, accessible after the trial. For several years the Star-Oddi loggers have been used by the biomedical industry in virology, vaccinology and in studies that require accurate measurements. All DSTs are delivered with calibration certificates to ensure compliance with GLP.

Heart rate measurements

The DST-HRT loggers, in micro and milli size simultaneously measure long term heart rate and core temperature. This makes them ideal for studies in which baseline and immunology responses are recorded; they are also suitable for toxicological, metabolic and thermoregulation studies.

The heart rate is derived from a leadless single channel ECG in which the electrodes are part of the housing material, making the logger especially easy to implant. The logger takes a burst measurement on any set time interval and calculates the mean heart rate for each recording. For validation purposes, each individual burst is graded with a certain quality index (QI) accessible in the accompanying application software.

Temperature measurements

The Star-Oddi DST temperature loggers in nano, micro, milli and centi cizes, are well suited for recording constant temperature throughout your research with no disturbance to the animal or the subject. Being able to measure core temperature without human interference reduces the stress placed on the animal circumventing any consequential fluctuations in the temperature profile. This may also result in a reduction of the number of laboratory animals used, with fewer animals needed to obtain reliable temperature data.

Compact leadless design

Researchers appreciate the loggers small size, high accuracy and biocompatible material suitable for implantation. With the completely leadless design of the loggers the implantation surgery becomes minimally invasive.

Easy to use and reusable

The Star-Oddi loggers are simple in use, from setup and surgery to data retrieval. The measurement data can be analyzed in graphic and tabular form and exported to most statistical analysis programs. The same logger can be reused as long as the battery lasts. When data has been retrieved the temperature logger can easily be sterilized and reset for new recordings. We recommend using gas or ethanol sterilization for our loggers.
