Description
Technical field
The present invention relates to a kind of Medical oxygen bags to supply oxygen amount control device, more particularly to a kind of for Medical oxygen bag oxygen supply
The medical supplies of flow control.
Background technology
Oxygen therapy technology：Oxygen is the necessary material that body carries out aerobic metabolism, generates energy, and oxygen therapy is to pass through difference
Oxygen-supplying technology, make the fraction of inspired oxygen (FiO of patient2) it is higher than the oxygen concentration (21%) of air, correct body anoxic to reach
Purpose, have medical oxygen source be implement oxygen therapy technology premise.
Medical oxygen source：The oxygen source that Hospitals at Present implements clinical oxygen supply includes mainly low-temperature liquid oxygen tank, oxygen bottle, oxygen bag
Deng.Low-temperature liquid oxygen tank (- 183 DEG C, 1MPa) oxygen storage capacity is very high, volume 1m3The releasable atmospheric oxygen capacity of liquid oxygen tank be about
860m3, the equipment process for using is more complex, and oxygen supply oxygen source uses centered on being typically mounted at the oxygen station of hospital.Hospital is normal
40L oxygen bottles are high pressure oxygen source (maximum working pressure 15MPa), and releasable atmospheric oxygen capacity is about 6000L, oxygen
Steel cylinder have the characteristics that oxygen storage capacity it is high, can oxygen supply time length, but the equipment there are weight big (50kg or more), it is not easily shifted,
The shortcomings of needing to be oxygenated using special high-pressure equipment, therefore generally mostly used as fixed oxygen source or Central oxygen-supply oxygen source.It is small-sized
Oxygen bottle can be used as the mobile interim oxygen supply oxygen source used, but the equipment equally exists that weight is larger, it is special to need to use
The shortcomings of high-tension apparatus is oxygenated generally is only used as the oxygen source that lung ventilator supplies oxygen temporarily and uses.Medical oxygen bag belongs to low pressure oxygen source,
Has the characteristics that oxygenation use convenient, light-weight, easy to remove, but its oxygen storage capacity is less, is supplied oxygen temporarily frequently as the short time
Oxygen source use.
Medical oxygen bag oxygen-supplying technology：Medical oxygen bag is that clinical most common low pressure moves oxygen source at present.Do not having
It is patients accepting oxygen inhalation using Medical oxygen bag in the medical area of high power capacity oxygen source (such as in transport process of urgent patient),
It is the major way that current clinical implementation supplies oxygen temporarily.(maximum working pressure after domestic 50L Medical oxygen bags are full of to greatest extent
10kp), atmospheric oxygen capacity is usually 55L or so, generally usable 20min or so.
The shortcomings that existing Medical oxygen bag oxygen-supplying technology：Oxygen bag belongs to low pressure oxygen source, does not have what oxygen exported automatically
Function, clinic commonly use manual compression method to maintain the output of oxygen, its usual oxygen flow is difficult to constant.Therefore, existing oxygen
Airbag oxygen-supplying technology, which exists, needs the drawbacks such as manual compression, oxygen flow are unstable, effective oxygen supply time is uncertain.
The improved technology of Medical oxygen bag oxygen supply：In December, 2016, Wang Fengqing disclose EOP auxiliary device
(CN205796184U), including sheet frame, the first pressing mechanism and the second pressing mechanism, oxygen bag is put into device so that oxygen
Bag can keep constantly exporting；In April, 2017, Cao Xinghua disclose Medical oxygen bag pressure device (CN206081250U),
Add sandwich bag body on oxygen bag bag body, exhaled gas collector is arranged in breathing bag head end, using the gas of exhalation by interlayer
Bag body is blown afloat, and to generate pressure, automatic compressed oxygen airbag carries out supplemental oxygen to breathing bag；2 months 2018, the public affairs such as Wang Jie
Opened it is a kind of can Automatic-boosting and controllable gas flow oxygen bag (CN206964858U), including outer cover, spring, pushing
The structures such as plate, oxygen bag, gas outlet, adjustable valve, outtake tube, oxygen bag is put into the outer cover of the utility model, can
It realizes the supercharging effect of oxygen bag, and regulates and controls the output flow of oxygen by adjustable valve.
The deficiency of above-mentioned improved technology：Above-mentioned utility model technology has used external pressurized mode to maintain oxygen bag
Pressure, can overcome the shortcomings that oxygen cannot export automatically in the prior art, but the operating pressure of above-mentioned technology be difficult to it is constant,
It is difficult to solve existing oxygen bag oxygen-supplying technology there are oxygen output flows unstable, effective uncertain drawback of oxygen supply time,
And above-mentioned facility haves the shortcomings that volume is big, cumbersome.
