Document Type and Number:
Japanese Patent JP2017018335
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve safety property to a patient who uses a respiration auxiliary device.SOLUTION: A respiration auxiliary device 1 for assisting respiration of a patient comprises a pressure release part 8 for releasing abnormal pressure, when a control circuit part C of the respiration auxiliary device 1 becomes in a control loss state, and pressure of gas discharged from the respiration auxiliary device 1 is abnormal pressure. The pressure release part 8 comprises a pressure release valve V2 and a packing Pk. The pressure release valve V2 is for example, formed of a leaf spring, and is configured to open by the abnormal pressure generated due to control loss of the respiration auxiliary device 1. Therefore, if the control circuit part C of the respiration auxiliary device 1 becomes in the control loss state, gas of abnormal pressure is prevented from being supplied to a patient, so that safety property to a patient who uses the respiration auxiliary device 1 is improved.SELECTED DRAWING: Figure 4
