Title:
BREATHING APPARATUS WITH BREATHING-INTERLOCKING ELECTRIC FAN
Document Type and Number:
Japanese Patent JP2018015168
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a breathing apparatus with a breathing-interlocking electric fan preventing a large current from flowing to an electric fan when starting energization for holding a face-body internal pressure to a prescribed target positive pressure value and preventing the face-body internal pressure from largely falling below the prescribed target positive pressure immediately after starting the energization for holding the face-body internal pressure to the prescribed positive pressure value.SOLUTION: A breathing apparatus with a breathing-interlocking electric fan includes: a face body 1 for covering a part or the whole of a face; an inhalation valve 2 and an exhalation valve 3 attached to the face body 1; an electric fan 4 for supplying an outside air to the inside of the face body 1 via the inhalation valve 2; a filter 5 for filtering the outside air to be sucked by the electric fan 4; a breathing monitor device 7 that has a membrane member 6e deformed according to fluctuation in the face-body internal pressure, and sensors 7a and 7b for detecting the deformation of the membrane member 6e; and a control device 8 that controls the actuation of the electric fan 4 in conformity with breathing, on the basis of a detection signal of the breathing monitor device 7. The control device 8 energizes the electric fan 4 with a minute electric current to rotate the electric fan 4 at a minute number of rotations.SELECTED DRAWING: Figure 2
