Abstract
The utility model discloses a constant-pressure oxygen inhaler. The constant-pressure oxygen inhaler comprises a valve seat, a high pressure chamber is arranged in the valve seat, a low pressure chamber is positioned outside the valve seat, the lower end of the high pressure chamber is provided with an oxygen inlet, a spring is positioned in the high pressure chamber, the top of the spring is pressed by the lower end of a push rod, the upper part of the push rod is connected with a low pressure chamber diaphragm, a constant-pressure spring pad is positioned on the upper end surface of the push rod, a constant-pressure spring is positioned upon the constant-pressure spring pad, the low pressure chamber is connected with a safety valve and a humidifying bottle, the humidifying bottle is connected with a humidifying tube, the upper end of the humidifying tube is connected with an oxygen output regulation knob, and the humidifying bottle is provided with an oxygen outlet. The constant-pressure oxygen inhaler can depressurize the higher-pressure oxygen in a central oxygen supply pipeline and then keep the working pressure of the outputted oxygen constant at a preset value before the oxygen is supplied for oxygen therapy. Under the working condition that the inputted pressure and the outputted flow are changed, the constant-pressure oxygen inhaler can keep the outlet pressure stable, and can continuously regulate the flow of the oxygen outlet. The constant-pressure oxygen inhaler is used for treating patients in hospitals, and is applicable to the inhalation of the oxygen supplied by the central pipeline.
Description
Technical field
This utility model relates to the oxygen inhalation apparatus that a kind of hospital patient treatment is suitable for the central tube air feed.
Background technology
The oxygen inhalation apparatus that uses is mainly by table body, Pressure gauge, effusion meter, humidification bottle, Flow-rate adjustment knob at present, and compositions such as relief valve are controlled the gas output flow by regulating the Flow-rate adjustment knob, and patients oxygen sucks treatment.Do not possess voltage stabilizing function.When supply gas pressure changed, output gas pressure will be subjected to very big influence, and the air pressure shakiness influences patient.
Summary of the invention
In order to overcome the unsteady defective of existing oxygen inhalation apparatus air pressure, this utility model provides a kind of constant voltage oxygen inhalation apparatus, and this constant voltage oxygen inhalation apparatus has the constant voltage function, guarantees the air pressure steady air current.
The technical solution of the utility model is: this constant voltage oxygen inhalation apparatus comprises valve seat, be provided with the altitude chamber in the valve seat, low-pressure chamber is positioned at the valve seat outside, the lower end, altitude chamber is provided with air inlet, spring is positioned at the altitude chamber, the push rod lower end is pressed in above the spring, push rod top links to each other with the low-pressure chamber thin film, the constant force spring cushion block is positioned at the push rod upper surface, constant force spring is positioned at above the constant force spring cushion block, and low-pressure chamber is connected with relief valve and humidification bottle, and humidification bottle is connected with the humidifying pipe, humidifying pipe upper end is connected with the adjusting knob of giving vent to anger, and humidification bottle is provided with the gas outlet.
Advantage of the present utility model: the oxygen of the elevated pressures in the central gas-supply pipeline will be able to be exported the constant oxygen supply gas treatment use behind preset value of aero operating pressure after decompression.Under the working condition that input pressure and output flow change, all can keep stable outlet pressure, and can adjust the flow of gas outlet continuously.

The specific embodiment
In Fig. 1, this constant voltage oxygen inhalation apparatus comprises valve seat 15, is provided with altitude chamber 2 in the valve seat 15, and low-pressure chamber 4 is positioned at valve seat 15 outsides.2 lower ends, altitude chamber are provided with air inlet 1, spring 10 is positioned at altitude chamber 2, valve push rod 9 lower ends are pressed in above the spring 10, valve push rod 9 tops link to each other with low-pressure chamber thin film 5, and constant force spring cushion block 6 is positioned at valve push rod 9 upper surfaces, and constant force spring 7 is positioned at above the constant force spring cushion block 6, low-pressure chamber 4 is connected with relief valve 3 and humidification bottle 14, humidification bottle 14 is connected with humidifying pipe 13, and humidifying pipe 13 upper ends are connected with the adjusting knob 11 of giving vent to anger, and humidification bottle 14 is provided with gas outlet 12.
Under the pressure effect of constant force spring 7 and altitude chamber spring 10, the throttle clearance between valve push rod 9 and the valve seat 15 is in normally open.After the constant voltage oxygen inhalation apparatus is connected in the concentrated oxygen supply system, gases at high pressure enter altitude chamber 2 through high pressure admission mouth 1, throttle clearance between valve push rod 9 and valve seat 15 enters low-pressure chamber 4, through the adjusting knob 11 of giving vent to anger, humidifying pipe 13, humidification bottle 14, gas outlet 12 gas is exported.
Along with gases at high pressure enter low-pressure chamber 4, Pneumatic pipe cleaner crosses low-pressure chamber thin film 5 and constant force spring cushion block 6 promotes constant force spring 7 compressions, make valve push rod 9 in the throttle clearance of closing under the effect of altitude chamber spring 10 between valve push rod 9 and the valve seat 15, gases at high pressure can't enter low-pressure chamber 4.
Along with the output of the gas in the low-pressure chamber 4, low-pressure chamber 4 internal gas pressures reduce, constant force spring 7 oppositely promotes constant force spring cushion block 6, low-pressure chamber thin film 5, make valve push rod 9 in the throttle clearance of opening under the effect of altitude chamber spring 10 between valve push rod 9 and the valve seat 15, gases at high pressure enter low-pressure chamber 4, throttle clearance between valve push rod 9 and the valve seat 15 is switch repeatedly, and gas pressure in the stabilizing low voltage chamber 4 guarantees job demand.Adjust controlled atmosphere joint knob 11, the control output gas flow of gas changes, and reaches job demand.When quitting work, close the adjusting knob 11 of giving vent to anger.
Relief valve 3 is relief arrangements of safe handling and breaks down and send the device of signal.Because the valve sealing gasket damages or other reasons pressure when rising to 1.15-1.5 times of maximum output pressure voluntarily, relief valve 3 can be opened aerofluxus automatically when output pressure.When being reduced to allowable value, pressure then can close automatically.
