Title
(EN) BREATH MEASUREMENT DEVICE
(FR) DISPOSITIF DE MESURE DE L'HALEINE
(JA) 呼気測定装置
Abstract
(EN) 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).
(FR) L'invention concerne un détecteur de débit (12) dans un dispositif de mesure d'haleine (1) comprenant : un corps de tuyau (20), dont un côté première extrémité est pourvu d'un orifice d'entrée (21) à travers lequel s'écoule l'haleine, et dont un côté seconde extrémité est pourvu d'un orifice de sortie (22) à travers lequel s'écoule l'haleine ; et d'un capteur de pression différentielle (23) qui est relié au corps de tuyau (20). Le corps de tuyau (20) comprend : une garniture de séparation (28) qui divise l'intérieur du corps de tuyau (20) en un espace d'entrée d'haleine (32) et un espace de sortie d'haleine (33) ; un trou de raccordement (35) qui est disposé sur le côté de l'espace d'entrée (32) et relie le capteur de pression différentielle (23) à l'espace d'entrée (32) ; un trou de connexion (36) qui est disposé sur le côté de l'espace de sortie (33) et relie le capteur de pression différentielle (23) à l'espace de sortie (33) ; et un tuyau d'air mince et long (29) qui pénètre dans l'emballage de compartiment (28) de façon à relier l'espace d'entrée (32) et l'espace de sortie (33).
(JA) 呼気測定装置(1)の流量検出器(12)は、第1端側に呼気が流入する流入口(21)、第2端側に呼気が流出する流出口(22)が設けられたパイプ体(20)と、パイプ体(20)に接続された差圧センサ(23)と、を有している。パイプ体(20)は、パイプ体(20)の内部を呼気の流入空間(32)と呼気の流出空間(33)とに分割する分割パッキン(28)と、流入空間(32)側に設けられており差圧センサ(23)を流入空間(32)に接続する接続孔(35)と、流出空間(33)側に設けられており差圧センサ(23)を流出空間(33)に接続する接続孔(36)と、分割パッキン(28)を貫通して流入空間(32)と流出空間(33)とを連通させる細長形状の通気管(29)と、を有している。
