Problems solved by technology

[0004] However, oxygen has combustion-supporting properties. Therefore, when using a medical oxygen supply device, although smoke and fire are strictly prohibited around, the user (patient) or the user's family members or caregivers near the device may smoke when using the device or there is a stove, etc. Using the device near fireworks may cause the extension tube connected to the nasal oxygen tube and the mask to catch fire and cause a fire accident, etc.

no. 1 approach

[0056] figure 1 It is an external perspective view of the medical oxygen supply device 1 according to the first embodiment of the present invention viewed obliquely from the upper left front. In order to minimize the installation space, the medical oxygen supply device 1 has an appearance shape that is elongated in the vertical direction and looks like a small travel bag at first glance. Therefore, others do not know that it is the medical oxygen supply device 1 at first glance.

[0057] In addition, in addition to reducing the weight to about one-third of the weight of conventional devices and pursuing energy saving, the feature of the present invention is that the included rechargeable battery and household power supply can be used. In addition, the rechargeable battery can also be used as a backup power source during a power outage, so it can be used with peace of mind. Furthermore, in the rechargeable battery use mode, when the oxygen flow rate is set to 1.25 L per minut...

[0099] Figure 4 It is an external perspective view of the medical oxygen supply device 1001 according to the second embodiment of the present invention viewed obliquely from the upper left front.

[0100] Many structures of the medical oxygen supply device 1001 of the present embodiment are the same as those of the medical oxygen supply device 1 of the above-mentioned first embodiment, therefore, the same structures are assigned the same reference numerals and the description thereof is omitted, and the following description will focus on the differences. .

[0101] In this embodiment, the difference from the above-mentioned first embodiment is that the ultraviolet sensor 1221 is installed near the oxygen outlet 7 . The ultraviolet sensor 1221 uses a ZnO ultraviolet sensor, a GaN ultraviolet sensor, an AlGaN ultraviolet sensor, a diamond ultraviolet sensor, etc. Figure 5 The block diagram of the medical oxygen supply device 1001 shows that the ultraviolet sensor 1221 is lo...

[0112] Figure 7 It is an external perspective view of the medical oxygen supply device 2001 according to the third embodiment of the present invention viewed obliquely from the front and upper left.

[0113] Many structures of the medical oxygen supply device 2001 of the present embodiment are the same as those of the medical oxygen supply device 1 of the above-mentioned first embodiment, and therefore the same structures are assigned the same symbols and descriptions thereof are omitted, and the following description will focus on the differences. .

[0114] In this embodiment, in Figure 7 The top of the oxygen outlet 7 shows the step portion 71 formed on the oxygen outlet 7 (refer to Figure 9 , Figure 10 ) is snapped into an airtight state, and a resin-made coupling 13 that can be attached and detached freely.

[0115] In addition, in this embodiment, an infrared sensor 2221 is attached near the oxygen outlet 7 instead of the temperature sensor 221 of the first embod...

Abstract

The invention provides a clinical oxygen feeding device. An oxygen inhalation therapy using a conventional device at home may be caused to have a fire at the oxygen inhaling port of a nose cannula or a mouth mask by a smoking action or to have an ignition by using the device near the presence of a fire such as a stove, thereby inviting a fire. Provided is a clinical oxygen feeding device comprising a means for acquiring highly dense oxygen, a warning means for warning of an accident with voices when the accident occurs, and a control means for controlling those two means. The clinical oxygen feeding device further comprises a temperature sensor at a proper position of the body thereof, so that the device stops the feed of the highly dense oxygen and executes a voice guide when the temperature detected by the temperature sensor becomes a predetermined value or higher.

Description

technical field [0001] The present invention relates to a medical oxygen supply device which may cause a fire due to an accident etc., and more particularly relates to a medical oxygen supply device equipped with a mechanism for suppressing the spread of fire or preventing fire. technical background [0002] Conventionally, an adsorption method using zeolite as an adsorbent has been widely used in medical oxygen supply devices used in oxygen inhalation therapy, which is effective as a treatment method for patients with respiratory diseases such as asthma, emphysema, and chronic bronchitis. The zeolite permeates oxygen in the air and selectively adsorbs nitrogen. [0003] In addition, this kind of medical oxygen supply device is a device that is usually placed in the residence by home patients. Therefore, in order to ensure the safety of the operation of the medical oxygen supply device, it also has the function of detecting abnormal pressure, abnormal concentration of genera...
