Title: DEVICE AND METHOD FOR NON-INVASIVE MEASUREMENT OF SUBDIAPHRAGMATIC AORTIC FLOW IN A SMALL LABORATORY MAMMAL
Abstract:
The invention relates to a device for non-invasive measurement of aortic flow in the subdiaphragmatic region in a small laboratory mammal, characterised in that it comprises: - a device for plethysmography of the thorax by inductance measurement, comprising two electrically conducting, extendible coils (2, 3) rigidly attached to an elastic garment (1) that is adjustable to the torso of said mammal (A), - a device (4) for acquiring the signal from variation in the cross-section of each coil, - a processor (6) configured to calculate the instantaneous subdiaphragmatic aortic flow of said mammal from said signals from the variation in cross-section of each coil and from a functional model of the cardiorespiratory system, according to which the exchanges of blood between the thorax and the rest of the body of said mammal consist of an output of blood via the abdominal aorta in the subdiaphragmatic region and an input of blood via the inferior vena cava.
