ERGOSPIROMETRY SYSTEM FOR ANIMALS, ESPECIALLY HORSES, CAMELS OR THE LIKE

摘要

The invention relates to an ergospirometry system for animals, especially horses, camels or the like. The inventive system comprises a funnel-shaped, cylindrical or hemispherically shaped respiratory gas mask (4), a gas volume flow sensor or flow sensor as well as a measuring unit comprising sensors for detecting the CO2/O2 concentration in the respiratory gas according to the mixing chamber or breath-by-breath principle. Said system also comprises connecting and/or signal transmitting means for further processing, representing and/or analysing measured values in a base station. According to the invention, means for fixing (4) a volume flow sensor housing (3) that can be detached from the mask are provided on the respiratory gas mask. Said housing is provided with flow chambers. Moreover, flow channels are formed within the flow chambers by parallel screens (19) which extend in the direction of flow, are spaced apart from each other and are provided with openings that are arranged in an offset manner and have a cross-section that can be predetermined. The centres of gravity or central points of said openings are essentially situated on an imaginary connecting line. Ultrasound converters (22) are located on the end points of the imaginary lines for detecting the volume flow. The invention also relates to a special pneumatic control that can be used according to the mixing chamber principle and in a continually operated gas suction pump (27).
