Detailed Introduction

The Whole-body Plethysmograph (WBP) developed by Tow-Int Tech is capable of measuring respiratory parameters of laboratory animals in conscious state and under unrestrained condition, such as respiratory rate, tide volume, Airway Hyperresponsiveness (AHR) test, etc.

Product Description

The Whole-body Plethysmograph (WBP) developed by Tow-Int Tech is capable of measuring respiratory parameters of laboratory animals in conscious state and under unrestrained condition, such as respiratory rate,tide volume, Airway Hyperresponsiveness (AHR) test, etc. WBP avoids the trauma of aerosols tube incision and the effects of anesthesia, making the whole experimental process simpler. It is used to study the reaction of animal models to drugs, the pharmacology and toxicology of respiratory drugs, especially suitable for a large badge animal models for rapid initial screening test, long-term follow-up research and repetitive screening.

Product Features

lNo operation is required and the instrument is easy to use

lMulti-channel simultaneous monitoring

lIt can be used in the study of respiration of animals in the natural state and long-term follow-up experiment, which is suitable for initial screening of drugs

lDrug aerosol atomization module is available

lAutomatic calibration function

lThere are drinking water and food ports for long-term continuous monitoring

lOptional functions are available, for example the measurements of ECG, blood pressure, body temperature, heart rate and other vital signs, which can be combined with implantable telemetry equipment

lEquipped with analysis software, data can be saved in Excel or TXT format
