Erosion effectively extends stainless steel steel wire filter screen 10.
In use, by power switch 31 measuring device 3 is powered, the gas with hand extruding gasbag 1, inside air bag 1
The inside that L-type bend pipe 5 enters cylindrical type cylinder 8 is passed sequentially through, filtering will be passed through under the action of stainless steel steel wire filter screen 10
The gas of device 2 is filtered purification, and purified gas enters the inside of tube body 13, sequentially enters pressure gauge 27 and gas stream
Pressure inside tube body 13 is shown and is referred to for medical staff by quantity sensor 24, pressure gauge 27, while gas flow senses
Device 24 will be uploaded to dsp controller 26 by its internal gas flow data, and dsp controller 26 is by received gas flow number
According to after handling by analysis, with the data of tidal volume, touching display screen 28 is come out simultaneously, convenient for medical staff according to touching display screen
28 data shown accurately grasp the tidal volume of patient's sucking, aobvious by touch-control to obtain preferably therapeutic effect
The alarm parameters of buzzer 29 are arranged in display screen 28, and when the tidal volume for supplying patient is greater than the set value, dsp controller 26 controls bee
The device 29 that rings is alarmed, and can effectively prevent the gas flow amount of overstepping the extreme limit supplied to patient, the safe treatment to patient is effectively ensured.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
