Title:
BREATH MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/150738
Kind Code:
A1
Abstract:
A flow rate detector (12) in a breath measurement device (1) has: a pipe body (20), a first-end side of which is provided with an inflow port (21) through which breath flows in, and a second-end side of which is provided with an outflow port (22) through which breath flows out; and a differential pressure sensor (23) which is connected to the pipe body (20). The pipe body (20) has: a partitioning packing (28) that partitions the interior of the pipe body (20) into a breath inflow space (32) and a breath outflow space (33); a connection hole (35) that is provided on the inflow space (32) side and connects the differential pressure sensor (23) with the inflow space (32); a connection hole (36) that is provided on the outflow space (33) side and connects the differential pressure sensor (23) with the outflow space (33); and a thin and long air pipe (29) which penetrates the compartment packing (28) so as to connect the inflow space (32) and the outflow space (33).
