Detailed description of the invention
Fig. 1 is the structural schematic diagram of the oxygen flow alarm in an embodiment of the present invention；
Fig. 2 is the operation principle schematic diagram of the oxygen flow alarm in embodiment described in the utility model.
Specific embodiment
It elaborates with reference to the accompanying drawing to the specific embodiment of oxygen flow alarm provided by the utility model.
Referring to figure 1 and figure 2, the utility model provides a kind of oxygen flow alarm comprising: a pedestal 1, described
One oxygen tubing string 2 is installed on pedestal 1.In the present embodiment, the oxygen tubing string 2 is made of transparent glass.Certainly, at other
In section Example, the oxygen tubing string 2 can also be made of other materials, but need to meet the condition of light transmission.The oxygen
Tubing string is the unified tubing string of clinical apparatus of oxygen supply.
Multiple scales are set on the tube wall of oxygen tubing string 2, and the scale includes one corresponding with safe oxygen flow maximum value
The first scale and second scale corresponding with safe oxygen flow minimum value.If oxygen flow in oxygen tubing string 2 is more than the
One scale is lower than the second scale, then oxygen concentration can be caused not to be inconsistent with clinical requirement.Therefore, it is necessary to control in oxygen tubing string 2
Oxygen flow is between the first scale and the second scale.
One floating ball 3 is set in the oxygen tubing string 2, and the floating ball 3 is by oxygen flow size variation and along the oxygen hose
The vertical direction of column 2 is mobile.When the oxygen flow in oxygen tubing string 2 is bigger, then make floating ball 3 along the vertical of oxygen tubing string 2
Direction rises, and when the oxygen flow in oxygen tubing string 2 is smaller, then declines floating ball 3 along the vertical direction of oxygen tubing string 2.
In the present embodiment, a regulating switch 7 is set on the pedestal 1, and the regulating switch 7 is for adjusting the oxygen tubing string 2
Oxygen flow.
A setting position (such as third graduation position) between the first scale and the second scale is equipped with a light sensor
Device 4, the photosensitive sensor 4 include a transmitting terminal and a receiving end (figure does not mark).The photosensitive sensor 4 and the floating ball
3 one detection circuits of formation (figure does not mark).The detection circuit is connected with a warning circuit.In the present embodiment, the alarm
Circuit further comprises a buzzer (figure does not mark), for playing tweeting sound.
Furthermore, the original position of the position of the photosensitive sensor 4 and floating ball 3 is same level.When described
Floating ball 3 is gradually increasing due to being become larger by the oxygen flow in oxygen tubing string 2, and the receiving end is described by initially having not been able to receive
The light that transmitting terminal is issued gradually becomes and can receive the part light that the transmitting terminal is issued, until becoming to receive
The whole light issued to the transmitting terminal.Therefore, in the process, the resistance value of detection circuit changes, and resistance value is by becoming greatly
It is small.
Equally, when the floating ball 3 is gradually reduced due to being become smaller by the oxygen flow in oxygen tubing string 2, the receiving end by
It initially has not been able to receive the light that the transmitting terminal is issued, gradually becomes and can receive the part that the transmitting terminal is issued
Light, until becoming that whole light that the transmitting terminal is issued can be received.Therefore, in the process, the resistance value of detection circuit
Also it changes, resistance value is also from large to small.
Therefore, the first threshold and second threshold of Standard resistance range, the first threshold and safe oxygen flow can be preset
The resistance value of detection circuit when maximum value is corresponding, the resistance value of the second threshold and detection circuit when safe oxygen flow minimum value
It is corresponding.
The detection circuit for detected resistance whether within a preset range, the preset range by first threshold and
Depending on second threshold.When resistance value is more than first threshold or second threshold, the detection circuit can trigger warning circuit and issue announcement
Alert sound, in this way, it is possible to during having ensured clinical care and home oxygen therapy with oxygen safety.
