The utility model can also reach by following measure:

In the middle of the described envelope air cushion pit is arranged, there is an annular recess at the back side

Described pressure regulator is made up of adjustable tracheae and air valve pipe, the bottleneck middle part of bottle loam cake upper end is provided with inside annular projection, adjustable tracheae is arranged at bottleneck top threadably, air valve pipe upper end passes annular projection and part is set in the adjustable tracheae, the underpart is that the cylindric of amplification of one is stuck in below the annular projection, the pit of underpart inner fovea part and envelope air cushion forms vaporizing chamber, breathing pipe in adjustable tracheae and the air valve pipe communicates, and adjustable tracheae and air valve pipe are made by nonmetallic material.

Described engage thread is realized by the screw that tapped nut that places bottleneck top and one are fixed on adjustable tracheae corresponding site, being provided with bottle cap outside bottleneck threadably is limited to nut in the bottleneck, on the air valve pipe, be with the cushion rubber that can prevent the gas leakage effect, cushion rubber be squeezed in the purpose that reaches sealing on the annular projection upper surface by adjustable tracheae lower end surface.

The cap of the affixed standard interface in adjustable tracheae upper end.

The utility model has following advantage compared to existing technology:

1. easy to operate;

2. safe in utilization, prevent irrelevant personnel's improper operation;

3. gas output is easy to adjust, gives vent to anger evenly;

4. can not produce harmful matter.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in the figure, this intravenous injection formula medical oxygen bottle structure, comprise body 1, cap 11, be fixed in the bottle loam cake 2 on the body, the affixed breathable protective lid 3 in outlet port in the bottle loam cake 2, its special way is, the bottle loam cake 2 that is positioned at above the breathable protective lid 3 has been wholely set a ring platform 12, be placed with an envelope air cushion 4 on the ring platform 12, in the middle of the envelope air cushion 4 pit 16 is arranged, there is an annular recess 17 at the back side, between envelope air cushion 4 and bottle loam cake 2 inwalls slit 19 is arranged, envelope air cushion 4 is provided with pressure regulator, regulate the slit 19 little purposes that adjust tolerance that reach greatly by controlling the size that this pressure regulator acts on the power of envelope on the air cushion 4, pressure regulator is made up of adjustable tracheae 10 and air valve pipe 5, the bottleneck middle part of bottle loam cake 2 upper ends is provided with inside annular projection 13, adjustable tracheae 10 is arranged at bottleneck top threadably, air valve pipe 5 upper ends are by passing in the bottleneck and part is set in the adjustable tracheae 10, air valve pipe underpart 14 is cylindric annular projection 13 lower surfaces that are stuck in of the amplification of one, the pit 16 of underpart inner fovea part 15 and envelope air cushion forms vaporizing chamber 20, breathing pipe in adjustable tracheae 10 and the air valve pipe 5 communicates, described engage thread is realized by the screw 9 that tapped nut 8 that places bottleneck top and one are fixed on adjustable tracheae 10 corresponding sites, being provided with bottle cap 7 outside bottleneck threadably is limited to nut 8 in the bottleneck, on air valve pipe 5, be with the cushion rubber 6 that can prevent the gas leakage effect, cushion rubber 6 is squeezed on annular projection 13 upper surfaces cap 11 of the affixed standard interface in adjustable tracheae 10 upper ends by adjustable tracheae 10 lower end surfaces.
