Slar small animal implantable telemetry system

Animal Physiology Remote Sensing Systemtelemetry

The measurement technology for remote wireless collection of implanted electron emission data in animals is called telemetry technology. The TSE Slar telemetry system adopts advanced technology to improve system performance, convenience, and stability, surpassing any telemetry acquisition system in the existing basic research field.

The pressure sensor of the catheter can solve various problems of traditional liquid filled catheters, such as slow frequency response, pressure, and noise generated by animal movement.

A receiver can monitor up to 256 animals. And 256 animals can be in one area or multiple areas at the same time.

The emission range of implanted particles in animals is 5 meters, without the need for a special platform or removal of the animal from the feeding cage for data collection.

The price of the rat Slar telemetry system is only a fraction of similar products. The price of implants is only equivalent to the maintenance cost of similar products. Based on the TSE * manufacturing process, all Slar emitters are disposable products, so they can be directly discarded after the experiment without any maintenance costs. This can save both repair time and repair costs. When conducting large-scale experiments, this advantage becomes particularly evident and can help you save a significant amount of money. The implanted memory chip can store data for 2 hours. The Slar telemetry system control program can independently control the acquisition parameters and time of each implanted subunit. After the program is completed, each implant can upload the collected data to the computer according to the main program. The core technology of Slar implants is that each implant contains its own memory. This is adopted in telemetry technology, where data collection can continue even if the animal is moved out of the receiving range, and when the animal is returned to the receiving range, the collected data can be uploaded to the computer on its own. Therefore, users can collect data without worrying about whether animals are within the collection range.

Analyze software modules

ECG module

The ECG software module can automatically analyze electrocardiogram data from multiple species. Professional analysis templates can accurately record the occurrence, duration, and amplitude of PQRST.

Users can also customize analysis templates based on electrocardiogram files and save them for future use.

The main parameters include average heart rate, heart rate classification, as well as the ability to remove outliers and extract raw data. Data can be exported as images or text files.

The software module is compatible with all data acquisition and analysis systems of Slar telemetry systems.

The ASCII text import module can convert electrocardiogram data collected by other programs into text format.

The standard PV data for rats includes: left ventricular pressure (LVP), left ventricular volume (LVV), phase, amplitude, rise/fall rate (dP/dt), and XY distribution maps of left ventricular pressure and volume. The blood pressure volume loop (PV Loop) automatic annotation function can also be used to display key descriptions and upload edited data in real-time to online journals for comparison.
