Device for evaluating respiratory data

Abstract

Title: Device for evaluating respiratory data The invention relates to a device for evaluating respiratory data comprising: • a body (10) extending along a longitudinal direction (L) between a proximal end (11), intended to be placed opposite the face of a user, and a distal end (12) opposite the proximal end, the body (10) having an internal passage opening at said ends (11, 12); • a grid (13) extending in the internal passage transversely to the longitudinal direction (L), the grid (13) comprising holes (131) each comprising a first opening (133) opening on the side of the proximal end (11) and a second opening (134) opening on the side of the distal end (12). A portion of the wall of each hole (131) of the grid (13) includes a chamfer (132), said portion extending to the second opening (134). Figure for the abbreviation: Fig. 4.
