According to the anti-leakage oxygen breathing machine, the oxygen output and the exhaust air discharging are effectively controlled by the one-way valves at the joint of the oxygen exit pipe and the constant pressure chamber and on the side wall of the oxygen exit pipe; the oxygen leakage is prevented even under a non-breathing state; a circle of lint is arranged at the inner edge for breathing, so that the wearing comfort level of the respirator is greatly increased.
Description
Technical field
This utility model relates to respirator technical field, relates in particular to a kind of anti-gas-leak oxygen respirator.
Background technology
The patients such as the crowd who works in anaerobic environment and cardiovascular and cerebrovascular disease asthma often need oxygen uptake, once yet current oxygen respirator will given vent to anger after opening always, when patient does not need oxygen uptake again sometimes because self is handicapped or other reasons cannot be closed respirator immediately, cause leaking outside of oxygen, caused unnecessary waste.
Utility model content
In order to solve existing the problems referred to above, this utility model provides a kind of anti-gas-leak oxygen respirator, and under respirator duty, patient's respirator can not leak gas even without wearing yet, and patient and air-breathingly just can not give vent to anger, need how much gas just to go out how much gas, can not waste.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of anti-gas-leak oxygen respirator, it is characterized in that: comprise air accumulator, constant voltage chamber, escape pipe, between described air accumulator and constant voltage chamber, by airway, be connected, airway is provided with constant pressure valve, the indoor pressure inductor that is provided with of constant voltage, one end of escape pipe is connected with constant voltage chamber, and the other end is provided with respirator, on escape pipe and the joint portion of constant voltage chamber and the sidewall of escape pipe, is equipped with unidirectional valve.
Preferably, described unidirectional valve comprises ventilation sheet and cover plate and sidewall, and ventilation sheet and cover plate are all arranged in the middle of sidewall, and cover plate covers on ventilation sheet, and the two connects by micro-power spring axle, and described ventilation sheet is provided with some passages.
Preferably, described escape pipe is comprised of outer tube and inner tube, and described inner tube sidewall is provided with air-vent, in the interlayer forming, is provided with granular active carbon between outer tube and inner tube, and its particle diameter is greater than air-vent diameter.
Preferably, described respirator inside edge part is provided with a circle flannelette pad.
Preferably, described cover plate is circle with ventilation sheet.
The beneficial effect that this utility model reaches is: by the unidirectional valve between constant voltage chamber and escape pipe and on escape pipe sidewall, effectively controlled the output of oxygen and the discharge of waste gas, even if guaranteed also can not cause oxygen to leak under the state of no breathing, and by greatly having improved the comfort level that respirator is worn breathing the circle flannelette shop that inside edge arranges.

The specific embodiment
In order to further describe technical characterstic of the present utility model and effect, below in conjunction with the drawings and specific embodiments, this utility model is described further.
Referring to figs. 1 through Fig. 5, a kind of anti-gas-leak oxygen respirator, comprise air accumulator 1, constant voltage chamber 2, escape pipe 3, between described air accumulator 1 and constant voltage chamber 2, by airway 4, be connected, airway 4 is provided with constant pressure valve 5, is provided with pressure inductor 8 in constant voltage chamber 2, and one end of escape pipe 3 is connected with constant voltage chamber 2, the other end is provided with respirator 6, on escape pipe 3 and the joint portion of constant voltage chamber 2 and the sidewall of escape pipe 3, is equipped with unidirectional valve 7.
In order to guarantee the unidirectional turnover of air-flow, described unidirectional valve 7 comprises ventilation sheet 71 and cover plate 72 and sidewall 73, ventilation sheet 71 is all arranged in the middle of sidewall 73 with cover plate 72, cover plate 72 covers on ventilation sheet 71, the two connects by micro-power spring axle 75, described ventilation sheet 71 is provided with some passages 74, and described cover plate 72 is circle with ventilation sheet 71.
In order to guarantee cleaning and being dried in escape pipe, described escape pipe 3 is comprised of outer tube 31 and inner tube 32, described inner tube 32 sidewalls are provided with air-vent, in the interlayer forming, are provided with granular active carbon between outer tube 31 and inner tube 32, and its particle diameter is greater than air-vent diameter.
In order to make the wearing more comfortable of respirator 6, described respirator 6 inside edge parts are provided with a circle flannelette pad 61.
During use, under original state, unidirectional valve 7 is in air-tight state, oxygen in air accumulator 1 slowly enters constant voltage chamber by airway 4, by indoor pressure inductor 8 induction air pressures of constant voltage, by the constant pressure valve 5 on airway 4, constant voltage chamber 2 internal gas pressures are adjusted to identical with external atmosphere pressure and are kept always, now because inner and outer air pressure equates, the unidirectional valve 7 of the joint portion of escape pipe 3 and constant voltage chamber 2 is still in air-tight state, the air pressure that respirator starts escape pipe 3 one sides when air-breathing on patient wear starts to reduce, with respect to constant voltage chamber 2 one sides, produce negative pressure, because the torsion of micro-power spring axle 75 is very little, the negative pressure pressure producing is easy to its counteracting, cover plate 72 on unidirectional valve 7 between constant voltage chamber 2 and escape pipe 3 is opened to escape pipe 3 one sides, oxygen enters escape pipe by the passage 74 on ventilation sheet 71, by patient, sucked, when patient exhales, negative pressure disappears, effect lower cover slip 72 at micro-power spring axle 75 covers rapidly on ventilation sheet 71, path between constant voltage chamber 2 and escape pipe 3 is blocked, now along with patient continues to exhale, pressure in escape pipe 3 constantly increases, air-flow backs down outside the cover plate 72 of unidirectional gas 7 on escape pipe 3 sidewalls is thought, waste gas is discharged, unidirectional valve when again air-breathing on sidewall is because escape pipe 3 internal pressures reduce and close rapidly, unidirectional valve 7 between constant voltage chamber and escape pipe 3 is opened again, along with continuing of breathing, this process moves in circles.
Above-described embodiment does not limit this utility model in any form, all take to be equal to replace or technical scheme that the form of equivalent transformation obtains, within all dropping on protection domain of the present utility model.
