Description

The breathing equipment of air-flow differential can be detected

Technical field

The present invention about relating to a kind of breathing equipment, espespecially a kind of breathing equipment of pressure directly detecting the air-flow that filtered device filters.

Background technology

Continuous positive airway pressure (ContinuousPositiveAirwayPressure, hereinafter referred to as CPAP) breathing equipment is widely used in armarium, for treating the major way of sleep apnea at present, there is provided continuous print pressure by CPAP breathing equipment to user's respiratory tract, breathe smooth and easy avoiding to make user and block.

CPAP breathing equipment is connected with group by the face shield of air tube and user, and pressure transducer is set in CPAP breathing equipment, the state that pressure transducer is breathed in order to detect user, namely the pressure of the air-flow produced when the user of importing in CPAP breathing equipment by air tube breathes is detected, correct and continuous print pressure when CPAP breathing equipment then provides user to breathe according to the testing result of pressure transducer.In addition, CPAP breathing equipment is directly touched by air tube due to the spittle may be produced when user is breathed, therefore between CPAP breathing equipment and air tube, defecator can be installed additional in air-flow transfer channel, enter in CPAP breathing equipment in order to intercept the spittle produced when user breathes by air tube, thus, just CPAP breathing equipment can be avoided to be subject to the spittle pollute, can reuse to make CPAP breathing equipment.

But, because defecator is arranged in the air-flow Transfer pipe between CPAP breathing equipment and air tube, the air-flow that the pressure of the air-flow detected by pressure transducer therefore in CPAP breathing equipment produces when being actually user breathing is by the pressure after filtration devices, but the pressure of air-flow when not passing through defecator by pressure and air-flow during defecator side is in fact different because of the obstruct of defecator, therefore the testing result of pressure transducer be in fact subject to defecator filtering effects and cannot directly and correctly reflect that user is breathed time the pressure of air-flow that produces, thus, CPAP device cannot control the pressure supplying user accurately.

In addition, in part CPAP device except there is pressure detector, also there is Fluistor and flow detector, wherein Fluistor flows through in order to allow air-flow, therefore air-flow is made to go out between air intake vent to produce pressure differential at Fluistor, pressure when flow detector is in order to detect the air intake vent of air-flow not by Fluistor and air-flow are by the pressure after the air outlet of Fluistor, with the difference of both calculating pressure, and then calculate the flow of air-flow, but Fluistor is set improves additionally causing the production cost of CPAP device.
