Embodiment Construction

[0057] According to the invention, an induction plethysmographic vest for a small mammal comprises a tube of elastic fabric configured to surround the torso of said mammal.

[0058] The tube includes a longitudinal axis substantially parallel to the animal's spine.

[0059] The tube may have a longitudinal closure, eg, along the spine of the animal, to facilitate placement of the tube on the torso. Such closures may include hook and loop type fastening elements (better known as VELCRO™), snap buttons, zippers, and the like.

[0060] Alternatively, the tube closes itself in a permanent manner, such as by welding, gluing, or sewing; it then has to be slipped over the animal's torso, with the elasticity of the fabric chosen so that it can be adjusted to slide over the animal's torso.

[0061] The tube serves as a support for at least one inductive winding formed by a bundle of conductive wires arranged in wavelet form along the circumference of said tube.

[0062] For this purp...

Abstract

The present invention concerns an inductance plethysmography vest for a mammal having a mass less than 6 kg, comprising: - a tube (10) made of resilient fabric configured to surround the trunk of said mammal, the tube (10) extending along a longitudinal axis (X) parallel to the vertebral column of the mammal; - at least one inductive turn formed of a strand (20) of electrically conductive wire arranged in the form of wavelets along the circumference of the tube (10); the vest being characterised in that it comprises at least one strap (11) made of resilient fabric, arranged along the circumference of the tube, defining a plurality of longitudinal loops (111), each wavelet being formed by the passage of the strand (20) of conductive wire successively in each loop (111).

Description

technical field [0001] The invention relates to an induction plethysmography vest for small mammals and a manufacturing method thereof. Background technique [0002] Inductive plethysmography is a tool for measuring changes in the trunk volume of a mammal (human or animal), for respiratory and / or cardiac applications. [0003] The principle of this measurement is an induction winding formed by winding at least one or more bundles of conductive wires around the subject's torso. Changes in torso volume, especially due to breathing and / or cardiac activity, cause changes in the inductance of each winding, which is measured by sensors. [0004] The reliability of the measurement requires ensuring that the position of the winding relative to the object is constant over time. In particular, any sliding of each winding relative to the subject's torso must be avoided. Furthermore, in the case of multiple consecutive recordings, it is necessary to position each winding at the same ...
