Document Type and Number:
Japanese Patent JP7020666
Kind Code:
B2
Abstract:
To allow detection of the amount of air discharged from a chest cavity to a chest cavity drainage unit without being affected by light from the outside.SOLUTION: A gas flow rate measuring device includes a flow rate calculating unit for calculating the flow rate of gas that has passed through a water sealing unit on the basis of the measured value of pressure measured by a pressure sensor in a water sealing unit or by a pressure sensor located above a suction pressure adjusting unit and below the water sealing unit.SELECTED DRAWING: Figure 3
