Abstract

PROBLEM TO BE SOLVED: To allow an operator manually and surely to turn on and off the device by installing a power on/off means close to the operator at the time of mounting on a vehicle in a device provided with a generating means generating enriched gaseous oxygen and a feeding means for feeding the enriched gaseous oxygen to use. SOLUTION: In a case when a respioratory disease patient uses a mobile gas feeding device 6 to be used for a home oxygen therapy on vehicle, a fuse 2 is fixed to a plus-side wiring from a battery 1 in an engine room to wire to the device 6 through a relay 3, an on/off means 4 and a power source connector 5. The relay 3 is made to turn on/off by synchronizing with on/off of an engine and wiring for on/off of this relay 3 is wired to the key switch of the vehicle so that the relay 3 may be turned on/off at the position of the ignition of the key switch. Thus, on/off is manually operated without regard to the installing position of the device.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile gas supply device used mainly for home oxygen therapy by patients with respiratory illness, and more particularly to a mobile gas supply device used in a vehicle. It relates to power ON-OFF.

[0002]

2. Description of the Related Art In recent years, medical respiratory gas supply apparatuses have been focused on oxygen therapy for providing oxygen-enriched gas to patients with respiratory diseases, especially oxygen therapy at home. became. As a result, they were released from hospitalization due to oxygen therapy at home, and many people returned to social life, such as going out, traveling, or working at a company.

[0003] In these oxygen therapies, means for supplying an oxygen-enriched gas include a high-pressure oxygen cylinder, a liquid oxygen cylinder, an oxygen concentrator, and the like. Oxygen concentrators have become widespread due to infinite supply.

When an oxygen concentrator is used, it is common to connect a nasal cannula called an oxygen cannula to the device to continuously send a constant flow of oxygen-enriched gas to a patient. In addition, the device is generally installed at home, so that no special consideration was given to the weight and size of the device, and it was impossible for the patient to use it when going out. Instead, portable small high-pressure oxygen cylinders and portable small liquid oxygen cylinders are often used when patients go out, but the amount of oxygen in these oxygen cylinders is limited, and Since the cylinder cannot be refilled, the usable time was limited by the set oxygen flow rate. As a result, the patient's range of action has been limited.

[0005] Therefore, recently, a mobile gas supply device which can be used with a battery and can be driven by a vehicle battery as a power source when mounted on a vehicle has been developed.
Long-term driving is possible without worrying about the remaining amount of oxygen. However, since the ON-OFF switch is attached to the device, depending on the position where the device is installed in the vehicle, turning ON / OFF the power supply is very painful for the patient. For example, in the case where the device is installed behind a vehicle that is out of reach, when turning on and off, it is necessary to go to the rear of the vehicle where the device that is out of reach is installed and perform ON-OFF each time. Was. Also, if the car engine is turned off with the device turned on, and if the car engine is started in that state, the device will start to drive together with the engine, resulting in a load on the car battery and causing a rise in battery and shortening the service life. I was

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem. When a mobile gas supply device is used in a vehicle, an operator can turn on the device at hand.
An object of the present invention is to provide a mobile gas supply device that can be turned off.

[0007]

SUMMARY OF THE INVENTION A pressure-variable oxygen concentrator having at least a generating means for generating an oxygen-enriched gas, and a supply means for using the oxygen-enriched gas, includes a power supply near the operator's hand when mounted on a vehicle. It is a mobile gas supply device characterized in that ON-OFF means is provided.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows wiring from a battery to a mobile gas supply device according to one embodiment of the present invention, which is wiring from an engine room to a vehicle interior.

As shown in FIG. 1, a fuse (2) is first attached to the + side wiring from the battery (1) in the engine room, and then a relay (3) and an ON-OF
The F means (4) is wired from the power connector (5) to the mobile gas supply device (6). First, it is preferable to select a fuse in accordance with the rated current of the device. Next is the relay, the relay is the engine ON-O
The relay is turned on and off in synchronization with the FF, and the wiring for turning the relay on and off is wired to the key switch of the car. The relay is turned on at the ignition position of the key switch.
It is preferable to perform wiring so as to be N-OFF. If the relay is turned on and off at this position, the battery does not run up because the engine is always running. If there is no relay, even if the ON-OFF means is installed, if it is in the ON state, it will be in the same state as that wired directly from the battery to the device, and even if the engine is not running, the battery will Is consumed, which causes the battery to run down. ON-OF for further wiring
Although a switch as F means is attached, the switch can be turned on and off by an operator at hand, and can be operated on and off at hand regardless of the installation position of the apparatus. Since the switch is used in a vehicle, it is preferable that the switch be turned on when ON so that ON-OFF can be clearly confirmed even at night. Further, it is preferable that the mounting position is fixed to the operator's hand. Thereafter, a power supply connector (5) is attached, and wiring for attaching the power supply connector to the mobile gas supply device (6) is provided.

[0010]

By using the present invention, when the power supply of the mobile gas supply device is turned on and off in a vehicle, the device can be reliably held by the operator regardless of the position in the vehicle. ON-OFF is possible, and it is an optimal device.
