Abstract
The utility model relates to an auxiliary respiratory apparatus which is the form of an air storage cavity of an air inlet provided with a one-way air inlet mechanism and an air outlet provided with the structure of filter layer material which can alternatively separate nitrogen gas in air. The auxiliary respiratory apparatus can be used by a patient or workers in oxygen-deficient environment in the field by enhancing the oxygen content of the gas in the air storage cavity.
Description
The utility model be a kind of when improving the air oxygen content and solve anoxic the assisted respirator of human body respiration.
The anoxic that a variety of causes causes, as lung's illness of human body self, or extraneous anaerobic environment such as high mountain plateau all can greatly influence the health of people's health.Solution to this problem mainly is to increase the oxygen content that sucks gas by the oxygen that supplies such as oxygen cylinder or oxygen bag are stored in advance at present.And the storage oxygen amount of any storage oxygen container is always limited, in case use up and in time do not change then easily cause danger.These containers and auxiliary equipment are generally all heavy simultaneously, use just to seem very inconvenient under mobilities such as mountain-climbing, rescue require to try one's best with light packs situation greatly and again.
The purpose of this utility model is the assisted respirator that provides a kind of simple in structure and the improved air oxygen content that can use continuously for a long time for addressing the above problem.
The main body of the utility model assisted respirator is the gas storage chamber of a sealing, for easy to use, preferably has at least a sidewall to be made by the material with certain degree of hardness.At least should offer one on the perisporium of gas storage chamber and have working off one's feeling vent one's spleen of the filtering layer formed by gas separation material with the extraneous air inlet that has unidirectional air intake structure that communicates and one.Wherein unidirectional air intake structure is except that can using various breather cheek valves, and the simplest mode is provided with a unidirectional flap valve structure exactly.Here said gas separation material should be able to make that airborne nitrogen is separated to be opened, and for example can reach this purpose at the sodium aluminium silicon composition zeolite molecular sieve of the multiple different content ratio that uses at present.It can optionally make airborne nitrogen by being separated, thereby has improved the oxygen content in the residual gas.Because these materials itself are not consumed, and can be constantly activating and regenerating repeatedly, therefore can use continuously for a long time.In order to guarantee that enough air storage amounts are arranged in the gas storage chamber, some mechanisms that can initiatively supply gas in gas storage chamber are set at the air inlet place to suit, for example miniature plenum fan or manual compression air bag etc. all can, and to be provided with these the two kinds mechanisms of supplying gas simultaneously for well, to guarantee reliable use.This form that has the mechanism of initiatively supplying gas is used in the environment of rarefaction of air and especially can be demonstrated its superiority and importance.The required energy of mini-fan can be supplied with by battery or civil power.Certainly, except that said structure, also should offer on the suitable position of gas storage chamber perisporium with the gas outlet, to send the gas of rich oxygen content in the gas storage chamber.
Assisted respirator of the present utility model can be according to using needs make various different types, wherein especially with helmet-type for well, be particularly suitable under situations such as mountain-climbing, rescue, using.Be provided with suitable solar cell this moment in the hard shell of the helmet to make power supply also very convenient.
Below specifically introduce structure of the present utility model by the example of a helmet-type assisted respirator shown in the drawings.
Fig. 1 structural representation of the present utility model
The gas storage chamber 6 that this routine assisted respirator is formed a sealing by the shell 1 and the soft liner 5 of rigid plastics compacting, offer some air inlets 3 that have unidirectional flap valve on the shell 1, wherein air inlet has and has miniature plenum fan 4 and two kinds of being supplied gas by manual gasbag.In addition, also have some gas outlets 2 that are provided with the zeolite molecular sieve structure of filtering layer that to select to isolate nitrogen on the shell 1, can make its one after the other work during use.When using for field works such as mountain-climbing, plateaus, suitable solar cell also can be set in the shell 1, as plenum fan or other power supply that needs, then can use common batteries or mains supply at ordinary times.Have on the suitable position of gas storage chamber 6 perisporiums with gas outlet 7, connects with suitable face shield by flexible pipe, for the breathing use.
Claims (7)
1, a kind of assisted respirator, it is characterized in that having the gas storage chamber (6) of a sealing, at least should have each one of air inlet (3) that can communicate and the gas outlet (2) that has structure of filtering layer on the wall of chamber with the external world, wherein the air inlet place should have unidirectional air intake structure, the filter course at gas outlet place is made up of the separable material that goes out nitrogen in the air, also should have on the appropriate location of gas storage chamber (6) perisporium for what breathe usefulness and export (7) with gas.
2, device as claimed in claim 1 is characterized in that said air inlet (3) located miniature supply fan (4) and supplied gas in gas storage chamber (6).
3, device as claimed in claim 1 is characterized in that said air inlet (3) located intraocular balloon and supplied gas in gas storage chamber (6).
4, device as claimed in claim 1 is characterized in that said unidirectional air intake structure is unidirectional flap valve form.
5, device as claimed in claim 1 is characterized in that said filter course material is a zeolite molecular sieve.
6, as the described device of one of claim 1 to 5, it is characterized in that said gas storage chamber (6) is a helmet-type, air inlet and gas outlet all are opened on its shell of being made by hard material (1).
7, device as claimed in claim 6 is characterized in that can being provided with solar cell in the said shell (1).
