Abstract

PURPOSE:To obtain a portable oxygen inhaler handy and with high portability by enabling the supply of oxygen enriched air without use of an oxygen cylinder. CONSTITUTION:An oxygen enriching module 10 is provided which concentrates oxygen of air to form an exygen enriched air. A pump 20 is connected to the oxygen enriched module 10 to suck air enriched by oxygen with the oxygen enrinching module 10. A battery 60 is provided to drive the pump 20 andan inhaling mask 50 is provided to which the oxygen enriched air sucked with the pump 20 is supplied.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable oxygen inhalation device that does not use an oxygen cylinder.

0002

BACKGROUND OF THE INVENTION Conventional portable oxygen inhalation devices use oxygen cylinders as a source of oxygen.

0003

[0006] Conventional portable oxygen inhalation devices that require an oxygen cylinder have poor portability due to the large weight of the oxygen cylinder, and require expense and effort to maintain and manage the oxygen cylinder. Furthermore, since the capacity of the oxygen cylinder is limited, there is also the drawback that the usable time is short. In view of this situation, an object of the present invention is to provide a portable oxygen inhalation device that is easy and highly portable and can supply oxygen-enriched air without using an oxygen cylinder.

0004

[Means for Solving the Problems] The present invention includes an oxygen enrichment module that condenses oxygen in air to produce oxygen-enriched air, and an oxygen enrichment module that is connected to the oxygen enrichment module, and that is connected to the oxygen enrichment module. The device is equipped with a pump that suctions the oxygen-enriched air, a battery that drives the pump, and an inhalation mask that is supplied with the oxygen-enriched air sucked by the pump.

[0005]

[Operation] By operating the suction pump, air is forcibly introduced into the oxygen enrichment module to generate oxygen enriched air. Oxygen-enriched air is then supplied to the inhalation mask by the suction force of the suction pump.

[0006]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The embodiment shown in FIG. 1 includes an oxygen enrichment module 10, a pump 20 whose suction port is connected to the oxygen enriched air outlet 11 of the oxygen enrichment module 10, and a blower 30 attached to the nitrogen-enriched air outlet 12; an inhalation mask 50 connected to the outlet of the pump 20 via an accumulator 40;
0 and a battery 60 for driving the blower 30, and a solar cell 70 connected in parallel to the battery 60.

The oxygen enrichment module 10 has a built-in oxygen enrichment membrane (not shown) and functions as follows. That is, when the switch 80 is closed and the pump 20 and the blower 30 are operated, the suction force of the pump 20 creates a pressure difference between one side and the other side of the oxygen enrichment membrane.
As a result, air is introduced into the module 10. The oxygen contained in the introduced air is dissolved, diffused and released by the action of the oxygen-enriching membrane, and as a result, the oxygen-enriched air outlet 11 contains a large amount of the released oxygen. Oxygen-enriched air, which is enriched with oxygen, is exhausted.

By the way, nitrogen contained in the air introduced into the oxygen enrichment module 10 has a slower dissolution speed than oxygen, and therefore the outside of the oxygen enrichment membrane becomes nitrogen enriched. If this nitrogen-enriched state is left unattended, the efficiency of generating oxygen-enriched air will decrease; however, the nitrogen-enriched air is sequentially discharged from the nitrogen-enriched air outlet 12 by the blower 30. , such inconveniences are prevented.

[0010] The oxygen-enriched air produced by the oxygen-enrichment module 10 is sent by a pump 20 to an accumulator 40, where it is pressured and smoothed. The oxygen-enriched air in the accumulator 40 is then supplied to the user via the inhalation mask 50. The accumulator 40 has a structure in which a container made of aluminum or an aluminum alloy is subjected to filament winding treatment, and therefore is lightweight and has high strength. Note that the battery 60 is a rechargeable battery, and is charged by a solar cell 70. Therefore, the pump 20 and the blower 30 can be operated for a long time.

The oxygen enrichment module 10 is arranged in a main body 91 of a carrying case 90 shown in FIG. are placed in each. The solar cell 70 is placed on the top surface of the lid 92 of the carrying case 90. Note that the oxygen enrichment module 1 is provided on the lower surface of the main body 91.
An opening (not shown) is provided for introducing air into the opening.

The oxygen inhalation device according to the above embodiment is highly portable since its weight including the carrying case 90 can be reduced to about 2 kg, and the oxygen inhalation device has a flow rate of 6 cm/min.
, air enriched with 30% oxygen can be supplied semi-permanently. Therefore, it is extremely effective as an oxygen supply means used to recover from fatigue in various sports and to refresh during meetings, studying, driving, etc. In addition, when it is fixedly installed in a car, an on-board battery can be used as the battery 60, and if the nitrogen-enriched air is discharged using so-called ram pressure, the blower 30 can be omitted. Can be done. however,
When used in a vehicle, it is necessary to provide a means for guiding nitrogen-enriched air outside the vehicle.

[0013]

[Effects of the Invention] The portable oxygen inhalation device according to the present invention does not require an oxygen cylinder, so it is highly portable and easy to handle. Therefore, it is ideal as an oxygen inhalation means for people who constantly need to inhale oxygen, and as an oxygen inhalation means that can be easily used at home, in a car, etc.
