Furthermore, the door control devices of described detection variations in flow, wherein, also arrange a LED lamp on described gating device, flicker report fault when described controlling device for doors breaks down.
Adopt such scheme, by arranging on the connection tube at oxygen face mask and oxygen supply end, detect and control device, realize when oxygen intake and the agent of medicament mixed mist, open the valve on connection tube, in the exhalation body during gas, valve closing on connection tube, can guarantee the accurate consumption of medicine, and avoid drug waste simultaneously.
The accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the present invention;
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of door control devices for detection of variations in flow, comprises oxygen face mask 1; Be provided with connection tube 2 on described oxygen face mask 1 and be wholely set with oxygen face mask 1, and setting is connected with outside oxygen supply end, wherein, be provided with checkout gear 4 and gating device 5 on described connection tube 2;
Described checkout gear 4, for detection of the flow direction of gas in described connection tube 2, and compare with default gas flow, the comparing result of output gas flow;
Described gating device 5 is connected with described checkout gear 4, be controlled by the by-pass valve control of closing or open described connection tube 2 that described comparing result is corresponding, by-pass valve control is arranged on the inside of gating device 5, when closing control valve, the gas channel of connection tube 2 is closed, and when opening by-pass valve control, the gas channel of connection tube 2 is opened.
Described checkout gear 4 and described gating device 5 all adopt the button cell power supply.
Furthermore, described default gas flow, for upwards, namely deviates from the direction of force of gravity, namely air-breathing direction.
Furthermore, the flow direction of gas in detecting described connection tube 2, and when identical with default gas flow, described controlling device for doors 5 is opened the by-pass valve control of described connection tube 2.
Furthermore, the flow direction of gas in detecting described connection tube 2, and when contrary with default gas flow, described controlling device for doors 5 is closed the by-pass valve control of described connection tube 2.
Preferably, described checkout gear 4 is a gas sensor, can detect the flow direction of sensing gas.
Furthermore, a round hole 3 in described oxygen face mask 1, the pressure of breath is born in the below that is arranged in described oxygen face mask 1 one sides for reducing oxygen face mask 1, prevent that connection tube 2 from coming off.
Furthermore, the diameter of described round hole is 0.2-0.3CM, 0.3CM preferably, the diameter of this opening, can average rate discharge gas in the body of breathing out, the oxygen of hybrid medicine can not discharged again, the more important thing is that opening is arranged on a side of connection tube 2, this angle is applicable to average rate and discharges gas in the body of breathing out, and the oxygen of hybrid medicine can not discharged again.
