SOLUTION: An air intake port 6 or an operation panel is provided to the top surface 7 of an apparatus main body 1 and set to the direct contact position with rainwater in the case of a rainy whether outdoor use in a state free from a cover 2. The cover 2 is not usually mounted and may be used only in a rainy weather case or may be always attached. In this case, the cover is mounted on the apparatus main body 1 by an attaching tool 3 and, in the case of the contact with the operation panel, the cover 2 is raised on its front side to achieve a purpose. In such a state that the cover 2 is mounted on the apparatus main body 1, an opening part 4 or a gap 5 is provided and the interior of the cover 2 is allowed to communicate with the open air by the opening part 4 or the gap 5. The cover 2 is made of any transparent material quality which may be colorless or colored and, for example, an acrylic resin or a polycarbonate resin is used.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a medical oxygen concentrator for supplying an oxygen-enriched gas having an oxygen concentration higher than that of air. More specifically, the present invention relates to a mobile oxygen concentrator capable of supplying an oxygen-enriched gas during movement.

2. Description of the Related Art Oxygen therapy for providing oxygen from an oxygen cylinder to a patient with respiratory disease has been performed. Recently, oxygen therapy using oxygen-enriched gas obtained by concentrating oxygen in the air has been developed. As a result, home oxygen therapy using a medical oxygen concentrator has become widespread. Many oxygen concentrators used in home oxygen therapy by patients with chronic respiratory disease are installed in homes and used. Home respiratory illness patients often go outside for the purpose of improving their quality of life, preventing their illness, rehabilitation, etc., rather than just staying at home. There is a demand for a suitable oxygen supply method. In order to satisfy this demand, portable small-sized high-pressure oxygen cylinders and portable small-sized liquid oxygen cylinders have been mainly used as necessary oxygen supply sources. However, the amount of oxygen in the oxygen cylinder or liquid oxygen container is limited, and the cylinder cannot be refilled when going out. Therefore, a demand for a mobile oxygen concentrator that can be used for a long time is increasing. The mobile oxygen concentrator is required to be small and light, to be mounted on a vehicle, to be mobile, and to be used for the purpose of use. Furthermore, for outdoor use, the position of the air intake is raised above the ground as much as possible so that cleaner air can be sucked in. In addition, the frequency of cleaning and replacement of the filter of the air intake is taken into consideration, and the replacement work is simplified. It is preferable to attach to a horizontal surface or an inclined surface of the top surface for the purpose of realization, and it is said that it is also preferable to arrange operation and display devices at the same position for operation. The function of the oxygen concentrator is particularly important for medical use, and its reliability is important.Since it is composed of sophisticated machinery and electrical circuits, the ingress of dust and rainwater in the event of outdoor use is limited by oxygen. There is a possibility that the concentrator will have a considerable adverse effect. In particular, the adsorbent in the adsorption cylinder used for oxygen concentration is necessary for patients with respiratory diseases because the nitrogen adsorption performance is extremely reduced when moisture is adsorbed, and as a result the original oxygen concentration performance of the device is reduced. This will cause a serious problem that the supply of oxygen-enriched gas cannot be performed. In consideration of workability and operability, it is desirable to provide an air inlet on the top surface of the apparatus main body as described above, but in this position, in case of rain, rainwater directly enters the air inlet.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mobile oxygen concentrator capable of securing a stable function by preventing dust and rainwater from entering the device when used outdoors, such as when moving a patient. is there.

SUMMARY OF THE INVENTION The present invention relates to a pressure fluctuation adsorption type oxygen concentrator having at least a generating means for generating an oxygen-enriched gas and a supply means for supplying the oxygen-enriched gas for use. A mobile oxygen concentrator characterized in that a cover is attached to the surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the drawings. FIG. 1 is a side view of one embodiment of the mobile oxygen concentrator according to the present invention. FIG. 2 is a top view of the mobile oxygen concentrator. An air inlet 6 and an operation panel are provided on a top surface 7 of the apparatus main body 1, and in a case where the cover 2 is not used, when it is used outdoors in rainy weather, it is a position directly hit by rainwater. The cover 2 may not be usually used and may be used only in rainy weather, or may be always attached as in the embodiment. In this case, the object is attached to the apparatus main body 1 by the attachment 3, and when touching the operation panel, the object is achieved by lifting the front of the cover 2. When the cover 2 is mounted on the apparatus main body 1, there are openings 4 and gaps 5 as shown in FIG.
And the gap 5 communicates with the outside air. When the mobile oxygen concentrator is used, the temperature of the apparatus main body 1 rises, and when the outside air temperature is lower than the temperature inside the cover, the water vapor contained in the air inside the cover is condensed on the inner surface of the cover to form a cover. Cloudiness. For this reason, there is a problem that the patient cannot check the instrument on the operation panel from outside. In order to prevent this problem, the outside air should easily enter the inside of the cover, and the temperature difference between the outside air and the inside of the cover should not be increased. Therefore, it is necessary to provide as many openings and gaps as possible between the cover 2 and the apparatus main body 1, and gaps and openings are provided substantially along the periphery of the cover as shown in FIG. 2. The opening is obtained by making a part of the cover into a convex shape, but the gap is obtained by making the cover dimension larger than the dimension of the top surface of the apparatus main body 1 by a predetermined gap. In this case, the cover is supported by several projections of the apparatus main body. The cover can be used as long as it is a transparent material. Even if the cover is not colorless but is colored, there is no problem if the transparency is maintained to the extent that the internal instruments can be confirmed.
For example, a commonly used acrylic resin, polycarbonate resin, or the like can be used.

As described above, the mobile oxygen concentrator according to the present invention enables a patient with chronic respiratory disease to easily go out even in bad weather and to act without worrying about time on the go.
As a result, the patient's rehabilitation can be quickened and the quality of life can be improved.
