（第１の実施の形態）
　図１は、本発明の第１の実施形態に係る医療用酸素供給装置１を前方左斜め上から見た外観斜視図である。この医療用酸素供給装置１は、設置場所を最小にするために上下方向に細長いスマートな、一見して小型旅行カバン風の外観形状を備えている。このため一瞥しただけでは他人に医療用酸素供給装置１であることが知られないように配慮している。 (First embodiment)
FIG. 1 is an external perspective view of a medical oxygen supply device 1 according to the first embodiment of the present invention as viewed from the upper left diagonal. The medical oxygen supply apparatus 1 has a smart and seemingly small travel bag-like appearance that is slender in the vertical direction in order to minimize the installation location. For this reason, consideration is given so as not to let others know that the device is a medical oxygen supply device 1 with a glance.
　また、特徴としては従来の装置の約三分の一の重さの軽量化、省エネを追求したことの他に、付属された充電式バッテリと家庭用電源で使用できることなどがある。また、充電式バッテリは停電時におけるバックアップ電源としても使用できるので安心して使える。さらに、充電式バッテリ使用モードでは酸素流量が毎分１．２５Ｌ以上に設定された場合には、バッテリ節約のために吸気に同調して酸素を送り出す「同調モード」に自動的に切り替わる機能を備えている。 Also, as a feature, in addition to pursuing light weight and energy saving of about one third of the conventional device, it can be used with the attached rechargeable battery and household power supply. The rechargeable battery can also be used as a backup power source in the event of a power failure. Furthermore, in the rechargeable battery usage mode, when the oxygen flow rate is set to 1.25L or more per minute, it has a function to automatically switch to the “tuned mode” in which oxygen is sent in synchronization with the intake air in order to save battery power. ing.
　表面カバー２ａと裏面カバー２ｂを射出成形樹脂部品とし、さらに吸着筒を含む他の構成部品についても極力軽量化することで総重量が約１０ｋｇの軽量化（ＡＣ電源使用でキャリアを設けない場合）とした。 The front cover 2a and back cover 2b are made of injection-molded resin parts, and other components including suction cylinders are also made lighter as much as possible to reduce the total weight to about 10kg (when using AC power supply and no carrier is provided) It was.
　この結果、大人が片手で持ち運べる、所謂可搬型にするための取手部分となるとともに、医療用酸素供給装置１を持ち上げる力に十分に耐え得る強度を備えるハンドル４を上方に設けており、デザイン的な特徴を演出している。 As a result, the handle 4 has a handle portion for making it a so-called portable type that can be carried by an adult with one hand, and provided with a handle 4 having a strength sufficient to withstand the force of lifting the medical oxygen supply device 1. Has produced a special feature.
　この医療用酸素供給装置１の外形寸法は、全体が丸みを帯びており、具体的には幅Ｗが３５０ｍｍ×奥行きＤが２５０ｍｍ×高さＨが５５０ｍｍである。このため、床面上の占有面積を極力小さくできることから上記の軽量化とともに小型化を図っている。 The outer dimensions of the medical oxygen supply device 1 are rounded as a whole. Specifically, the width W is 350 mm × the depth D is 250 mm × the height H is 550 mm. For this reason, since the occupation area on a floor surface can be made as small as possible, it is aiming at size reduction with said weight reduction.
　また、医療用酸素供給装置１のデザイン上の特徴点としては、設置床面から医療用酸素供給装置１の前面を３次元的に覆うようにした表面カバー２ａを、図１に示すようにハンドル４の底面に連続するアクセントラインを左右に上下方向に凹状に一体形成し、さらにこれらのアクセントラインで挟まれる部分を淡い暖色系とし、この上方に同色系の操作パネル５を配置する一方で、裏面カバー２ｂを含む残りの部分をベージュないしクリーム系の色としている。 Further, as a design feature of the medical oxygen supply apparatus 1, a surface cover 2a that covers the front surface of the medical oxygen supply apparatus 1 three-dimensionally from the installation floor is handled as shown in FIG. While the accent line continuous to the bottom surface of 4 is integrally formed in a concave shape in the vertical direction on the left and right, the portion sandwiched between these accent lines is a light warm color system, and the operation panel 5 of the same color system is disposed above this, The remaining part including the back cover 2b has a beige or cream color.
　以上のようなデザインおよび配色を施した所謂ツートンカラーの近代的なデザインとすることで、室内に医療用酸素供給装置１を設置したときに家具などの他の調度品との調和を図れるように配慮している。また、表面カバー２ａと裏面カバー２ｂは、耐衝撃性を有する熱可塑性樹脂である例えばＡＢＳ樹脂製とすることでデザイン的自由度を確保している。また、キヤリア１２上にボルト１２ａを介して医療用酸素供給装置１を載置し、キヤリア１２に一体的に設けられたキャスタ１２ｂにより室内などで移動を容易にしている。 By adopting a so-called two-tone modern design with the above design and color scheme, when the medical oxygen supply device 1 is installed indoors, it can be harmonized with other furniture such as furniture. Consideration. Further, the front cover 2a and the back cover 2b are made of, for example, ABS resin, which is a thermoplastic resin having impact resistance, thereby ensuring a degree of design freedom. Further, the medical oxygen supply device 1 is placed on the carrier 12 via a bolt 12a, and the caster 12b provided integrally with the carrier 12 facilitates movement in a room or the like.
　操作パネル５は、表示部１２８を備えており、ハンドル４の下方の開口部において裏面カバー２ｂとの接合面まで、例えば約１０度の角度で斜め上に延設され、その上に左から順に、電源スイッチ６と、酸素出口７と、酸素流量設定ボタン８が配置されている。この酸素出口７の上方には、酸素出口７に形成された段差部に対して気密状態に係合されるとともに、着脱自在に設けられる樹脂製のカプラ１３が示されている。このカプラ１３には長さ１～１５ｍ程度の延長チューブ１５の開口部が連通し、鼻カニューラ（酸素吸入具）１４の開口部が連通するようにセットされる。なお、延長チューブ１５は、塩化ビニル樹脂等で外径５～１０ｍｍ、内径３～６ｍｍ程度に形成されている。 The operation panel 5 includes a display unit 128. The operation panel 5 is extended obliquely upward at an angle of, for example, about 10 degrees up to the joint surface with the back cover 2b at the opening below the handle 4, and in order from left to right. A power switch 6, an oxygen outlet 7, and an oxygen flow rate setting button 8 are arranged. Above the oxygen outlet 7 is shown a resin coupler 13 which is engaged with a stepped portion formed in the oxygen outlet 7 in an airtight manner and is detachably provided. The coupler 13 is set so that the opening of the extension tube 15 having a length of about 1 to 15 m communicates with the opening of the nasal cannula (oxygen inhaler) 14. The extension tube 15 is made of vinyl chloride resin or the like and has an outer diameter of 5 to 10 mm and an inner diameter of 3 to 6 mm.
　操作パネル５は、標準身長（１６０～１７０ｃｍ）の患者が起立状態で両手を下げた腰部分に略該当する高さ付近に設けられているので、立ったままの姿勢で医療用酸素供給装置１の運転操作を行なうことができる。このため従来の装置のようにいちいち座ったり、覗き込んだりする必要がなくなる。したがって、特に患者の胸腹部への負担は大きく軽減される。さらには、左利きの人であっても酸素出口７を中央にして左右対称位置に各ダイヤルが配置されているので、何ら違和感なく操作できることになる。 Since the operation panel 5 is provided at a height approximately corresponding to a waist portion where a patient having a standard height (160 to 170 cm) stands and both hands are lowered, the medical oxygen supply device 1 is kept standing. Can be operated. For this reason, it is not necessary to sit down and look into each other like a conventional device. Therefore, the burden on the chest and abdomen of the patient is greatly reduced. Furthermore, even a left-handed person can operate without any sense of incongruity because the dials are arranged in symmetrical positions with the oxygen outlet 7 at the center.
　また、鼻カニューラ（酸素吸入具）１４に接続された延長チューブ１５を引っかけるための不図示のフックを設けてもよい。鼻カニューラ１４に接続された延長チューブ１５は、患者が生活する同じ部屋内で移動する範囲に略相当する全長を有しており、未使用時は、延長チューブ１５を数回巻き付けた後に、延長チューブ１５をフックに引っかける。 Further, a hook (not shown) for hooking the extension tube 15 connected to the nasal cannula (oxygen inhaler) 14 may be provided. The extension tube 15 connected to the nasal cannula 14 has a total length substantially corresponding to the range of movement in the same room where the patient lives. When the extension tube 15 is not used, the extension tube 15 is wound several times and then extended. The tube 15 is hooked on the hook.
　また、例えば患者が躓くなどして操作パネル５に対して激しくぶつかった場合でも、怪我などをしないように安全上の配慮がされている。この電源スイッチ６のオン位置に相当する位置には緑と赤に点灯する例えば発光ＬＥＤを内蔵した運転状態ランプ１２８ａが設けられている。また、この運転状態ランプ１２８ａの上にはバッテリ残量表示部１２８ｄが設けられている。 Also, for example, even if a patient hits the operation panel 5 violently, safety considerations are taken so as not to be injured. At a position corresponding to the ON position of the power switch 6, for example, an operation state lamp 128 a incorporating a light emitting LED that is lit in green and red is provided. Further, a battery remaining amount display portion 128d is provided on the operation state lamp 128a.
　また、中央の酸素出口７についても図示のように殆どの囲い部分が操作パネル５の操作面から奥側（図面の裏面側）に引っ込むように設けられており、さらに温度センサ２２１が酸素出口７に取り付けられている。この温度センサ２２１は、サーミスタ又は熱電対などが使用されており、また図２の医療用酸素供給装置１のブロック図を見ると、温度センサ２２１は、医療用酸素供給装置１本体内部に存在するが、一部或いは全体が本体表面に面していても構わない。この酸素出口７の上には「点検」の文字を印刷した警報表示部１２８ｃが設けられている。この警報表示部１２８ｃの下方には緑と赤に点灯する例えば発光ＬＥＤを内蔵した酸素ランプ１２８ｂが設けられている。また、設定した酸素流量（Ｌ／分）表示部１２８ｅも備えている。バッテリ残量表示部１２８ｄは、電源オンで約２秒間全点灯する。その後に、内蔵電池２２８の残量が１００％であると、５段階の発光ＬＥＤの全てが点灯表示される。また、バッテリ残量が２０％減るごとに、右側から消灯して点灯数が少なくなり、残り１つになると内蔵のブザーで警告する。 As shown in the figure, the central oxygen outlet 7 is also provided so that most of the enclosed portion is retracted from the operation surface of the operation panel 5 to the back side (the back side in the drawing), and the temperature sensor 221 is further provided. Is attached. The temperature sensor 221 uses a thermistor or a thermocouple, and the block diagram of the medical oxygen supply device 1 in FIG. 2 shows that the temperature sensor 221 exists inside the medical oxygen supply device 1 main body. However, a part or the whole may face the main body surface. On the oxygen outlet 7, an alarm display portion 128 c printed with “inspection” characters is provided. Below this alarm display portion 128c, there is provided an oxygen lamp 128b that incorporates, for example, a light emitting LED that lights in green and red. Moreover, the set oxygen flow rate (L / min) display part 128e is also provided. The battery remaining amount display portion 128d is fully lit for about 2 seconds when the power is turned on. Thereafter, when the remaining amount of the built-in battery 228 is 100%, all of the five levels of light emitting LEDs are turned on. Also, every time the remaining battery level is reduced by 20%, the light is turned off from the right side and the number of lights is reduced.
　そして、内蔵電池２２８の残量が１０％以下になると左側に設けられた発光ＬＥＤを内蔵したランプが赤色に点滅（間欠的に光る）するとともに、５分おきに内蔵のブザーで警告する。このようにして、特に外出時におけるバッテリ駆動モードでの使用上の安全性を確保している。警報表示部１２８ｃは「点検」の文字が印刷されており、酸素濃度が低下したときに内蔵のランプが点灯して知らせるようにしている。また装置側の異常発生時にはブザーが鳴り知らせるようにしている。また、停電で装置が停止したときには、点滅して知らせる一方で、ブザーを鳴らすことで特に視覚障害者に知らせるようにしている。酸素ランプ１２８ｂは、酸素が正常に流れているときには内蔵のＬＥＤが緑色に点灯し、酸素が出ていない時には消灯する。そして、呼吸同調モードのときに一定時間、呼吸状態を検出できなかったときに赤色に点灯し、ブザーを鳴らすようにしている。 And when the remaining amount of the built-in battery 228 becomes 10% or less, a lamp with a built-in light emitting LED provided on the left side flashes red (intermittently lights) and warns with a built-in buzzer every 5 minutes. In this way, safety in use in the battery drive mode is ensured particularly when going out. The alarm display section 128c is printed with the letters “check”, and a built-in lamp is lit to notify when the oxygen concentration is lowered. In addition, a buzzer sounds when an abnormality occurs on the device side. In addition, when the device stops due to a power failure, it blinks and notifies the visually impaired person by sounding a buzzer. The oxygen lamp 128b is turned off in green when the oxygen is flowing normally, and is turned off when oxygen is not emitted. When the respiratory state is not detected for a certain time in the respiratory synchronization mode, the light turns red and the buzzer sounds.
　なお、電源スイッチ６をオンすると、ブザーが鳴り、全てのランプが２秒間緑色に点灯する。そして、バッテリ駆動モードで使用するときには、その後に５段階の発光ＬＥＤにおいて残量に応じて点灯表示される。患者は医師の処方にしたがって酸素流量設定ボタン８で所定流量に設定すると、酸素供給が開始される。停止時には、電源スイッチ６をオフすると、酸素ランプ１２８ｂが消灯し、しばらくの間、運転ランプ１２８ａが点滅した後に自動的に終了する。患者が毎日行う作業として、裏面カバー２ｂに設けられた外気導入フィルタ２２に付着したゴミ、埃を掃除機で取り除くことがある。この作業を簡単にできるようにするために外気導入フィルタ２２を容易に着脱できるように構成されている。 When the power switch 6 is turned on, a buzzer sounds and all the lamps light up in green for 2 seconds. And when using it in battery drive mode, it lights up according to the remaining amount in 5 steps | paragraphs of light emission LED after that. When the patient sets the predetermined flow rate with the oxygen flow rate setting button 8 according to the doctor's prescription, the oxygen supply is started. At the time of stop, when the power switch 6 is turned off, the oxygen lamp 128b is turned off, and the operation lamp 128a flashes for a while and then automatically ends. As an operation performed by the patient every day, there is a case where dust and dirt attached to the outside air introduction filter 22 provided on the back cover 2b are removed with a vacuum cleaner. In order to facilitate this operation, the outside air introduction filter 22 is configured to be easily detachable.
＜医療用酸素供給装置１の配管およびブロック図の説明＞
　図２は、医療用酸素供給装置１のブロック図を兼ねて図示した配管の模式図である。本図において、既に説明済みの構成部品については同様の符号を附して説明を割愛する。図中の二重線は空気、酸素、窒素ガスの流路となる配管２４であり概ね配管２４で示されている。また、細い実線は電源供給または電気信号の配線を示している。 <Description of piping and block diagram of medical oxygen supply device 1>
FIG. 2 is a schematic diagram of the piping illustrated also serving as a block diagram of the medical oxygen supply apparatus 1. In the figure, components that have already been described are denoted by the same reference numerals and description thereof is omitted. The double line in the figure is a pipe 24 that is a flow path for air, oxygen, and nitrogen gas, and is generally indicated by the pipe 24. A thin solid line indicates power supply or electric signal wiring.
　ここで、以下の説明ではコンプレッサ１０として水平対向２筒式のコンプレッサを使用した場合について述べる。また、外気（空気）を吸気口２ｃ、フィルタ２２を介してコンプレッサ１０に導入し、排気口２ｄを介して外部に排出する主筐体２については密閉容器として図中において概ね破線で図示されている。 Here, in the following description, a case where a horizontally opposed two-cylinder compressor is used as the compressor 10 will be described. In addition, the main housing 2 that introduces outside air (air) into the compressor 10 through the intake port 2c and the filter 22 and discharges it to the outside through the exhaust port 2d is shown as a sealed container in the figure by a broken line. Yes.
　図２において、導入空気の流れに沿って順次述べる。吸気口２ｃ、フィルタ２２、配管２４を介して原料空気（外気）が図１に破線で図示した防音室３内に位置するコンプレッサ１０に入る。 In FIG. 2, description will be made sequentially along the flow of introduced air. The raw material air (outside air) enters the compressor 10 located in the soundproof chamber 3 shown by a broken line in FIG. 1 through the air inlet 2c, the filter 22, and the pipe 24.
　濾過された原料空気は、後述するコンプレッサ１０の圧縮機構で加圧されて圧縮空気となるが、このとき温度上昇した状態で配管２４が形成されたアルミ製の下部マニホルドＭ１（破線で示す）に送り出され下部マニホルドＭ１の放熱効果により冷却されるため、送風ファン３０の小型化が図れる。冷却された圧縮空気が第１吸着筒体１０８ａと第２吸着筒体１０８ｂに導入される。こうして、高温では機能低下してしまう吸着剤であるゼオライトが十分に機能できるようになる結果、酸素を９０％程度以上にまで濃縮できるようになる。 The filtered raw material air is pressurized by a compression mechanism of the compressor 10 to be described later to become compressed air. At this time, the temperature is raised in an aluminum lower manifold M1 (shown by a broken line) in which the pipe 24 is formed. Since it is sent out and cooled by the heat radiation effect of the lower manifold M1, the blower fan 30 can be downsized. The cooled compressed air is introduced into the first adsorption cylinder 108a and the second adsorption cylinder 108b. Thus, as a result of the function of zeolite, which is an adsorbent whose function deteriorates at high temperatures, oxygen can be concentrated to about 90% or more.
　圧縮空気は、配管２４を介して並列に２本分が上記のように配置された、第１吸着筒体１０８ａと第２吸着筒体１０８ｂに対して交互に供給されることになる。このため切換弁である３方向切換弁１０９ａ、１０９ｂが図示のように接続されている。これらの３方向切換弁１０９ａ、１０９ｂと、さらに第１吸着筒体１０８ａと第２吸着筒体１０８ｂの不要ガスを脱離させるための浄化工程を行うために、３方向切換弁１０９ａ、１０９ｂに対して配管２４が図示のように接続されている。 Compressed air is alternately supplied to the first adsorption cylinder body 108a and the second adsorption cylinder body 108b, which are arranged in parallel as described above via the pipe 24. For this reason, the three- way switching valves 109a and 109b, which are switching valves, are connected as shown in the figure. In order to perform a purification process for desorbing unnecessary gases from these three- way switching valves 109a and 109b and the first and second adsorption cylinders 108a and 108b, the three- way switching valves 109a and 109b The pipe 24 is connected as shown in the figure.
　以上の第１吸着筒体１０８ａと第２吸着筒体１０８ｂ内に夫々貯蔵されている触媒吸着剤であるゼオライトは、Ｓｉ０２／Ａｌ２Ｏ３比が２．０～３．０であるＸ型ゼオライトであり、かつこのＡｌ２Ｏ３の四面体単位の少なくとも８８％以上をリチウムカチオンと結合させたものを用いることで、単位重量当たりの窒素の吸着量を増やせるようにしている。特に約０.３～０.６ｍｍ程度の顆粒測定値を有するとともに、四面体単位の少なくとも８８％以上をリチウムカチオンと融合させたものが好ましい。 Or of the first adsorption cylinder 108a and zeolite catalyst adsorbent are respectively stored in the second adsorption column body 108b is, X-type Si0 2 / Al 2 O 3 ratio of 2.0-3.0 The amount of nitrogen adsorbed per unit weight can be increased by using zeolite which is obtained by binding at least 88% or more of the tetrahedral unit of Al 2 O 3 with a lithium cation. In particular, a granule measurement value of about 0.3 to 0.6 mm and a fusion of at least 88% or more of tetrahedral units with a lithium cation are preferable.
　このようなゼオライトを使用することで、同じ酸素を生成するために必要となる原料空気の使用量を削減できるようになる。この結果、圧縮空気を発生するためのコンプレッサ１０をより小型のタイプとすることができ、一層の低騒音化を図ることができる。 Using such a zeolite makes it possible to reduce the amount of raw material air required to generate the same oxygen. As a result, the compressor 10 for generating compressed air can be of a smaller type, and further noise reduction can be achieved.
　一方、第１吸着筒体１０８ａと第２吸着筒体１０８ｂの上方の出口側には逆止弁と、絞り弁と開閉弁とからなる均等圧弁１０７が図示のように分岐接続されている。分離生成された９０％程度以上の濃度の酸素を貯蔵するための容器となる製品タンク１１１が、図示のように配管２４に対して接続されている。 On the other hand, an equal pressure valve 107 including a check valve, a throttle valve and an on-off valve is branched and connected to the outlet side above the first adsorption cylinder 108a and the second adsorption cylinder 108b as shown in the figure. A product tank 111 serving as a container for storing separated and produced oxygen having a concentration of about 90% or more is connected to the pipe 24 as shown in the figure.
　製品タンク１１１の下流側には、出口側の酸素の圧力を一定に自動調整する所謂レギュレータである圧力調整器１１２が配管されている。この圧力調整器１１２の下流側には、後述する酸素濃度センサ１１４が配管２４を介して接続されており、酸素濃度の検出を間欠（１０～３０分毎）または連続で行うようにしている。この下流側には上記の酸素流量設定ボタン８に連動して開閉する比例開度弁１１５が配管２４を介して接続されており、その下流側には酸素流量センサ１１６がさらに接続されている。また、酸素流量センサ１１６の下流には呼吸同調制御のための負圧回路基板１１８を介してデマンド弁１１７が接続されており、滅菌フィルタ１１９を経て、医療用酸素供給装置１の酸素出口７に対して接続されている。以上の構成により、鼻カニューラ１４等を経て患者に対する最大流量５Ｌ／分で約９０％程度以上に濃縮された酸素の吸入が可能になる。 A pressure regulator 112, which is a so-called regulator that automatically adjusts the oxygen pressure on the outlet side to a constant level, is piped downstream of the product tank 111. An oxygen concentration sensor 114, which will be described later, is connected to the downstream side of the pressure regulator 112 via a pipe 24 so that the oxygen concentration is detected intermittently (every 10 to 30 minutes) or continuously. A proportional opening valve 115 that opens and closes in conjunction with the oxygen flow rate setting button 8 is connected to the downstream side via a pipe 24, and an oxygen flow rate sensor 116 is further connected to the downstream side. A demand valve 117 is connected downstream of the oxygen flow sensor 116 via a negative pressure circuit board 118 for breathing synchronization control, and passes through the sterilization filter 119 to the oxygen outlet 7 of the medical oxygen supply device 1. Are connected to each other. With the above configuration, it is possible to inhale oxygen concentrated to about 90% or more through the nasal cannula 14 and the like at a maximum flow rate of 5 L / min.
　次に、電源系統は、コネクタ１３０を中継して接続されるＡＣアダプタ１９と、主筐体２の底部に内蔵される内蔵電池２２８と、上記のコネクタ１３１を介して着脱自在可能に設けられる外部電池２２７と電源制御回路２２６から構成されている。内蔵電池２２８および外部電池２２７は繰り返し充電可能な２次電池であり、内蔵電池２２８は電源制御回路２２６からの電力供給を受けて充電される。なお、内蔵電池２２８は、少なくとも５００回程度の繰り返し充放電が可能で、電池残量、使用充放電サイクル数、劣化程度、出力電圧等のマネジメント機能を有するものが使用され、電池残量、残充電容量、充放電回数を外部の携帯端末などで確認可能なマネジメント機能を有するものが好ましい。また、外部電池２２７については、コネクタ１３１を介する接続状態において、電源制御回路２２６からの電力供給を受けて充電することもできるが、通常は別途準備される電池充電器を用いて繰り返し充電されることになる。または、専用設計された電池充電器を一体化した外部電池２２７として準備しても良い。 Next, the power supply system includes an AC adapter 19 that is connected via the connector 130, an internal battery 228 that is built in the bottom of the main housing 2, and an external that is detachably provided via the connector 131. A battery 227 and a power supply control circuit 226 are included. The internal battery 228 and the external battery 227 are rechargeable secondary batteries, and the internal battery 228 is charged by receiving power from the power supply control circuit 226. The built-in battery 228 can be repeatedly charged and discharged at least about 500 times, and has a management function such as the remaining battery level, the number of charge / discharge cycles used, the degree of deterioration, and the output voltage. What has a management function which can confirm charge capacity and the frequency | count of charging / discharging with an external portable terminal etc. is preferable. In addition, the external battery 227 can be charged by receiving power from the power supply control circuit 226 in a connected state via the connector 131, but is normally repeatedly charged using a separately prepared battery charger. It will be. Or you may prepare as the external battery 227 which integrated the battery charger designed exclusively.
　以上の電源系統の構成において、医療用酸素供給装置１はＡＣアダプタ１９からの電力供給を受けて作動する第１電力供給状態と、内蔵電池２２８からの電力供給を受けて作動する第２電力供給状態と、外部電池からの電力供給を受けて作動する第３電力供給状態との３系統の電力供給状態の内の一つに自動切換えして使用されることになる。 In the configuration of the power supply system described above, the medical oxygen supply device 1 operates in response to the power supply from the AC adapter 19 and the second power supply that operates in response to the power supply from the internal battery 228. The state is automatically switched to one of three power supply states, ie, a third power supply state that operates by receiving power supply from an external battery.
　この自動切換えのための優先順位は上記の第１電力供給状態、第３電力供給状態、第２電力供給状態の順序で自動決定するように中央制御部２００により電源制御回路２２６が制御される。 The power supply control circuit 226 is controlled by the central control unit 200 so that the priority order for the automatic switching is automatically determined in the order of the first power supply state, the third power supply state, and the second power supply state.
　また、電源制御回路２２６には、ＩＤタグコード識別回路２３０がさらに接続される場合があり、後述するように携帯時に充電式電池切れとなる事態を防止できるようにしている。すなわち、携帯時に充電式電池切れとなる事態を防止するためには、複数の内蔵電池２２８を接続するモジュラー電源装置とすると良いが、このように複数の電池を接続すると電源切り替えの手段が複雑になる上、さらに個別に電力消費をモニタすることができなくなる。 In addition, an ID tag code identification circuit 230 may be further connected to the power supply control circuit 226 to prevent a situation where the rechargeable battery runs out when being carried, as will be described later. That is, in order to prevent a situation where the rechargeable battery runs out when being carried, a modular power supply device that connects a plurality of built-in batteries 228 may be used. However, when a plurality of batteries are connected in this way, the power switching means becomes complicated. Moreover, it becomes impossible to monitor power consumption individually.
　そこで複数の内蔵電池２２８、・・・２２８の内で、放電済の電池からフル充電された充電式電池に自動的に切り換える制御を可能にするために個別に識別ＩＤタグコード及び充電状態検出手段を設けておき、放電済の電池を確認可能にしてフル充電された電池に切り換えるようにしている。さらにまた、電池使用したい時間に合致させて、接続する電池の数を自由に選択し、利便性を高めるようにしている。 Therefore, among the plurality of built-in batteries 228,... 228, an identification ID tag code and a charge state detection means are individually provided to enable control to automatically switch from a discharged battery to a fully charged rechargeable battery. Is provided so that a discharged battery can be confirmed and switched to a fully charged battery. Furthermore, the number of batteries to be connected is freely selected according to the time when the battery is desired to be used, thereby improving convenience.
　また、中央制御部２００は、生成する酸素量に応じた、最適な動作モードに切り替えるプログラムが記憶されており、多くの酸素生成をする場合は自動的にコンプレッサ１０、送風ファン３０を高速駆動し、少ない酸素生成時の場合には低速に回転駆動する制御を行うモータ制御部２０１、ファンモータ制御部２０３を介して夫々行うことで、特に、内蔵電池２２８を温存させるようにしている。この結果、外部電池２２７を充電し忘れた場合であっても突然の外出時や停電時等の対応が可能になる。 The central control unit 200 stores a program for switching to an optimal operation mode according to the amount of oxygen to be generated. When generating a large amount of oxygen, the central control unit 200 automatically drives the compressor 10 and the blower fan 30 at high speed. In the case of generating a small amount of oxygen, the built-in battery 228 is particularly conserved by performing the control through the motor control unit 201 and the fan motor control unit 203 that perform the rotation drive at a low speed. As a result, even when the external battery 227 is forgotten to be charged, it is possible to cope with sudden outings or power outages.
　この中央制御部２００には所定動作プログラムを記憶したＲＯＭが内蔵されるとともに、外部記憶装置２１０と、揮発メモリと一時記憶装置とリアルタイムクロックからなる回路２０７がさらに接続されており、外部コネクタ１３３を介して通信回線などと接続することで記憶内容へのアクセスが可能となるように構成されている。 The central control unit 200 incorporates a ROM that stores a predetermined operation program, and is further connected to an external storage device 210, a circuit 207 including a volatile memory, a temporary storage device, and a real-time clock. The stored contents can be accessed by connecting to a communication line or the like via the communication line.
　また、上記の３方向切換弁１０９ａ、１０９ｂと均等圧弁１０７とをオンオフ制御することで、第１吸着筒体１０８ａと第２吸着筒体１０８ｂ内の不要ガスを脱離させるように制御する制御回路２０８と、上記の酸素濃度センサ１１４と比例開度弁１１５と、流量センサ１１６とデマンド弁１１７とを駆動制御する流量制御部２０２が中央制御部２００に接続されている。なお、酸素濃度センサ１１４にはガルバニ電池式、超音波式、ジルコニア式等のセンサが使用可能だが、大きさの点や測定精度の点からもジルコニア式酸素濃度センサが好ましい。 In addition, a control circuit that controls to desorb unnecessary gas in the first adsorption cylinder body 108a and the second adsorption cylinder body 108b by performing on / off control of the three- way switching valves 109a and 109b and the equal pressure valve 107. 208, a flow rate control unit 202 that drives and controls the oxygen concentration sensor 114, the proportional opening valve 115, the flow rate sensor 116, and the demand valve 117 is connected to the central control unit 200. The oxygen concentration sensor 114 may be a galvanic cell type, an ultrasonic type, a zirconia type, or the like, but a zirconia type oxygen concentration sensor is preferable in terms of size and measurement accuracy.
　総重量が約５００ｇのコンプレッサ１０は、モータ制御部２０１に内蔵される可変速度制御部により正弦波駆動波形でアウターロータ式の電動モータを含む直流モータの駆動制御が行われることで運転音を低くしている。 The compressor 10 having a total weight of about 500 g is driven by a variable speed control unit built in the motor control unit 201 so that the driving sound of the DC motor including the outer rotor type electric motor is controlled with a sinusoidal drive waveform. is doing.
　このコンプレッサ１０は、上記のように圧縮空気発生のみの機能を備えるものであり、取り出される酸素流量に応じて回転数が自動制御され、回転速度が５００ｒｐｍから３０００ｒｐｍの間で制御される。また、このコンプレッサ１０は、空気を６０～１５０ｋＰａ程度に圧縮する性能を備えている。 The compressor 10 has a function of generating only compressed air as described above, and the rotation speed is automatically controlled according to the oxygen flow rate taken out, and the rotation speed is controlled between 500 rpm and 3000 rpm. The compressor 10 has a performance of compressing air to about 60 to 150 kPa.
　このコンプレッサ１０を取り巻く操作温度は、０℃～４０℃であり、コンプレッサ１０の駆動電圧は、自動車やトラックなどのシガーライターアダプタから得られる電源である直流１２Ｖまたは２４Ｖであって、電力使用量は、約３０Ｗ程度である。このため、最悪の場合にはコネクタ１３１に接続して電源供給することもできる。下部マニホルドＭ１に放熱・冷却効果があるため、必要最小限のファンでよく騒音の低下、電力の低減に貢献する。 The operating temperature surrounding the compressor 10 is 0 ° C. to 40 ° C., and the driving voltage of the compressor 10 is DC 12V or 24V, which is a power source obtained from a cigarette lighter adapter such as an automobile or truck, and the power consumption is , About 30W. For this reason, in the worst case, the power can be supplied by connecting to the connector 131. Since the lower manifold M1 has a heat dissipation / cooling effect, a minimum necessary fan is sufficient, which contributes to noise reduction and power reduction.
　３方向切換弁１０９ａ、１０９ｂには、一般的に直動式と呼ばれる弁の動作を通電時の磁力で行う電磁弁が使用可能である。この種の電磁弁は電気の力だけで主弁を動作させるため消費電力が高いという問題点がある。そこで、３方向切換弁１０９ａ、１０９ｂとしてパイロット式３方向切換弁を使用することもできる。このパイロット式３方向切換弁によれば、僅かな消費電力とコンプレッサからの空気圧を有効利用して動作させることが出来るために従来の８Ｗから０．５Ｗにまで低減されるので大幅な電力低減が図れることになる。 As the three- way switching valves 109a and 109b, electromagnetic valves that perform a valve operation generally called a direct acting type by a magnetic force during energization can be used. This type of solenoid valve has a problem of high power consumption because the main valve is operated only by electric power. Therefore, a pilot-type three-way switching valve can be used as the three- way switching valves 109a and 109b. According to this pilot-type three-way selector valve, since it can be operated by using a little power consumption and the air pressure from the compressor, it is reduced from the conventional 8W to 0.5W, so the power consumption is greatly reduced. It will be planned.
　以上の各構成部品は、低騒音化された医療用酸素供給装置１の組立作業性および点検整備性の向上を配慮して、一方向から主に主筐体２をその取り付け部として固定できるように設計されている。すなわち、各種制御基板と、上記のように酸素の圧力を一定に自動調整する圧力調整器１１２と、圧力調整器１１２の下流側の酸素濃度センサ１１４と比例開度弁１１５と、酸素流量センサ１１６と呼吸同調制御のための負圧回路基板１１８に接続されるデマンド弁１１７を、全て一方向から固定できるように構成されている。特に振動または騒音発生の伴う構成部品は防音室３の内部において防音状態かつ防振状態で設けることで、圧縮空気の供給音と、外部空気の導入音と、原料空気を作るための濾過空気の導入音と周期的に発生する排気音が外部に漏れないようにして騒音低減を図っている。また、３方向切換弁の作動音は上記のように防音材（防音シート）１１で覆うことで防音している。さらに主筐体２は、その吸気口２ｃを介して内部に導入し、排気口２ｄを介して外部に排出する必要最小限の開口を備えた密閉カバーとして構成されることから、さらなる騒音低減を図ることが可能になる。 Each of the above components can be fixed mainly from one direction as its mounting portion in consideration of the improvement of assembly workability and inspection maintainability of the medical oxygen supply device 1 with reduced noise. Designed to. That is, various control boards, the pressure regulator 112 that automatically adjusts the oxygen pressure to be constant as described above, the oxygen concentration sensor 114, the proportional opening valve 115 on the downstream side of the pressure regulator 112, and the oxygen flow rate sensor 116. The demand valves 117 connected to the negative pressure circuit board 118 for breathing synchronization control can all be fixed from one direction. In particular, components that generate vibration or noise are provided in the soundproof room 3 in a soundproof and vibration-proof state, so that the supply sound of compressed air, the introduction sound of external air, and the filtered air for producing raw air Noise is reduced by preventing the introduction sound and the periodically generated exhaust sound from leaking outside. Further, the operation sound of the three-way switching valve is soundproofed by covering with the soundproofing material (soundproofing sheet) 11 as described above. Further, since the main housing 2 is configured as a hermetic cover having a minimum necessary opening that is introduced into the inside through the air inlet 2c and discharged to the outside through the air outlet 2d, further noise reduction is achieved. It becomes possible to plan.
＜温度センサ２２１の説明＞
　温度センサ２２１は、検知された温度が所定値以上になると、中央制御部２００にコンプレッサ１０の動作と、デマンド弁１１７を閉じ直ちに、濃縮酸素の供給を停止させ、音声ガイドを行う電気信号を送るようにしてある。この温度異常を知らせる電気信号により、中央制御部２００はモータ制御部２０１に対して、コンプレッサ１０の動作を停止させる電気信号を、流量制御部２０２に対しては、デマンド弁１１７を閉じ濃縮酸素の供給を停止させる電気信号を、送ることとなる。また、温度センサ２２１の検知する所定値は、設定温度が高すぎると延焼の抑制が難しくなり、設定温度が低すぎると誤作動の原因となるので、鼻カニューラ１４や延長チューブ１５のチューブ素材が塩化ビニル樹脂、ウレタン樹脂などであり、それら樹脂の耐熱温度が６０℃～１００℃であることを考慮すると、温度センサ２２１の検知される所定値は６０℃～１００℃の範囲であることが好ましい。 <Description of Temperature Sensor 221>
When the detected temperature becomes equal to or higher than a predetermined value, the temperature sensor 221 sends the electrical signal for voice guidance to the central control unit 200, the operation of the compressor 10 and the demand valve 117 are immediately closed to stop the supply of concentrated oxygen. It is like that. Based on the electrical signal informing the temperature abnormality, the central control unit 200 sends an electrical signal for stopping the operation of the compressor 10 to the motor control unit 201. For the flow rate control unit 202, the demand valve 117 is closed to close the concentrated oxygen. An electric signal for stopping the supply will be sent. Further, the predetermined value detected by the temperature sensor 221 is difficult to suppress the spread of fire if the set temperature is too high, and if the set temperature is too low, it may cause malfunction, so the tube material of the nose cannula 14 or the extension tube 15 is Considering that the heat resistant temperature of these resins is 60 ° C. to 100 ° C., the predetermined value detected by the temperature sensor 221 is preferably in the range of 60 ° C. to 100 ° C. .
　図３は、温度センサ２２１により医療用酸素供給装置１の温度の異常変化を検知して、コンプレッサ１０の動作と、濃縮酸素の供給を停止させ、音声ガイドを行う動作説明のフローチャートである。はじめに医療用酸素供給装置１が起動されるとステップＳ１０に進み、温度センサ２２１の計測が行われる。温度センサ２２１は、連続的又は消費電力を考慮して５分毎など断続的に装置本体の温度を計測することができ、ステップＳ１１において、検出した温度が予め設定した温度例えば６０℃以上のとき、ステップＳ１２に進み、温度センサ２２１から温度異常を検知した中央制御部２００は、モータ制御部２０１にコンプレッサ１０の動作を停止させ、流量制御部２０２に濃縮酸素の供給を停止させる（ステップＳ１２）。この後、ステップＳ１３において音声ガイドを行い、処理を終了する。一方、ステップＳ１１において、温度センサ２２１の検出した温度が６０℃に満たないとき、ステップＳ１０に戻り、上記のステップＳ１０から繰り返す。ステップＳ１２とステップＳ１３において、コンプレッサ１０の動作と濃縮酸素の供給が停止され、音声ガイドが実行されれば目的は達成されるので、ステップＳ１２とステップＳ１３の順序が逆であっても、又同時に実行されてもよい。 FIG. 3 is a flowchart for explaining the operation in which the temperature sensor 221 detects an abnormal change in the temperature of the medical oxygen supply device 1, stops the operation of the compressor 10 and the supply of concentrated oxygen, and performs voice guidance. First, when the medical oxygen supply device 1 is activated, the process proceeds to step S10 and the temperature sensor 221 is measured. The temperature sensor 221 can measure the temperature of the apparatus main body continuously or every 5 minutes in consideration of power consumption. When the detected temperature is a preset temperature, for example, 60 ° C. or more in step S11. In step S12, the central control unit 200 that has detected the temperature abnormality from the temperature sensor 221 causes the motor control unit 201 to stop the operation of the compressor 10, and causes the flow rate control unit 202 to stop supplying the concentrated oxygen (step S12). . Thereafter, voice guidance is performed in step S13, and the process is terminated. On the other hand, when the temperature detected by the temperature sensor 221 is less than 60 ° C. in step S11, the process returns to step S10 and is repeated from the above step S10. In steps S12 and S13, if the operation of the compressor 10 and the supply of concentrated oxygen are stopped and voice guidance is executed, the objective is achieved. Therefore, even if the order of steps S12 and S13 is reversed, May be executed.
＜音声ガイドの説明＞
　音声ガイドは、中央制御部２００によって制御された音声合成IC２５０が、音声ガイド手段としてのスピーカー２５１を介して、音声ガイドを実行する。このときスピーカー２５１は、音声ガイドが聞き取りやすい位置に設けてあれば良いので、医療用酸素供給装置１本体内部に限定することはなく、表示パネル５や医療用酸素供給装置１の表面などに設けてあってもよい。 <Description of voice guide>
For voice guidance, the voice synthesis IC 250 controlled by the central control unit 200 executes voice guidance via the speaker 251 as voice guidance means. At this time, the speaker 251 only needs to be provided at a position where the voice guide can be easily heard. Therefore, the speaker 251 is not limited to the inside of the medical oxygen supply device 1, and is provided on the surface of the display panel 5 or the medical oxygen supply device 1. May be.

　本実施の形態の赤外線センサ２２２１は、炎を検知すると、中央制御部２００にコンプレッサ１０の動作と、デマンド弁１１７を閉じ直ちに、濃縮酸素の供給を停止させ、酸素出口７とカプラ１３との接続を自動で解除し、音声ガイドを行う電気信号を送るようにしてある。この炎を知らせる電気信号により、中央制御部２００はモータ制御部２０１に対して、コンプレッサ１０の動作を停止させる電気信号を、流量制御部２０２に対しては、デマンド弁１１７を閉じ濃縮酸素の供給を停止させる電気信号を、カプラ１３の解除手段に対しては、カプラ１３と酸素出口７との接続を解除させる電気信号を、送ることとなる。このとき、カプラ１３の解除手段は、酸素出口７とカプラ１３との接続が中央制御部２００の制御により、自動的に解除されればよいので、例えば圧縮バネ等の弾性体の弾性力を利用した自動解除や電磁力による反発を利用したソレノイド式の自動解除などと如何なる手段を用いてもよい。尚、本発明のカプラ１３の解除手段の一実施形態については後述する。また、赤外線センサ２２２１の検知する異常温度は、設定温度が高すぎると延焼の抑制が難しくなり、設定温度が低すぎると誤作動の原因となるので、鼻カニューラ１４や延長チューブ１５のチューブ素材が塩化ビニル樹脂、ウレタン樹脂などであり、それら樹脂の耐熱温度が６０℃～１００℃であることを考慮すると、赤外線センサ２２２１の検知される異常な温度上昇が６０℃を超えたときであることが好ましい。 <Description of Infrared Sensor 2221>
When detecting the flame, the infrared sensor 2221 of the present embodiment closes the operation of the compressor 10 and the demand valve 117 to the central control unit 200 and immediately stops the supply of concentrated oxygen, and connects the oxygen outlet 7 and the coupler 13. Is automatically released, and an electrical signal for voice guidance is sent. The central control unit 200 sends an electric signal for stopping the operation of the compressor 10 to the motor control unit 201 by the electric signal notifying the flame, and supplies the concentrated oxygen to the flow rate control unit 202 by closing the demand valve 117. An electrical signal for stopping the connection is sent to the release means of the coupler 13 for releasing the connection between the coupler 13 and the oxygen outlet 7. At this time, the release means of the coupler 13 only has to automatically release the connection between the oxygen outlet 7 and the coupler 13 under the control of the central control unit 200. For example, the elastic means of an elastic body such as a compression spring is used. Any means such as automatic release or solenoid type automatic release using repulsion due to electromagnetic force may be used. An embodiment of the releasing means for the coupler 13 of the present invention will be described later. Further, the abnormal temperature detected by the infrared sensor 2221 is difficult to suppress the spread of fire if the set temperature is too high, and if the set temperature is too low, it may cause malfunction, so the tube material of the nose cannula 14 or the extension tube 15 is Considering that the heat resistance temperature of these resins is 60 ° C. to 100 ° C., such as vinyl chloride resin and urethane resin, the abnormal temperature rise detected by the infrared sensor 2221 may be when the temperature exceeds 60 ° C. preferable.
＜解除手段の構成の説明＞
　カプラ１３を自動で解除する解除手段の一実施形態について説明する。図９は、カプラ１３を自動で解除する解除手段の解除前、図１０は、カプラ１３を自動で解除する解除手段の解除後を示している。このカプラ１３は、前述したように、酸素出口７に形成された段差部７１に対して気密状態に係合されるようになっている（不図示）。解除手段の一実施形態として、圧縮バネ７２、ヒーター７３、バイメタル７４が解除手段に含まれるが、これに限定するわけではない。図９に示すように、圧縮バネ７２はL字形状を有するバイメタル７４によって、圧縮された状態で酸素出口７に備えられている。バイメタル７４は、熱膨張率の小さい金属板７４１（例えば、インバーなど）と、熱膨張率の大きい金属板７４２（例えば、FeとNiの合金に、Mn、Cr、Cu、Mgなどを添加したもの）とを貼り合わせたものである。バイメタルは温度の変化によって曲がり方が変化する性質があり、バイメタル７４は熱を加えると熱膨張率の小さい金属板７４１を内側に、熱膨張率の大きい金属板７４２を外側にして曲がる。この性質を利用し、バイメタル７４を変形させることで、圧縮された圧縮バネ７２を開放し、カプラ１３を自動解除する（図１０）。ヒーター７３は、バイメタル７４に熱を加える働きをし、中央制御部２００とつながっているため、中央制御部２００で温度調整や制御が可能である。これにより、中央制御部２００がヒーターを加熱制御することで、カプラ１３の自動解除を行なうこととなる。万が一、炎が発生した時に中央制御部２００がヒーターを加熱しなくとも、鼻カニューラや延長チューブに引火した炎によってバイメタル７４が温められるので、カプラ１３は自動解除される。本実施形態では、医療用酸素供給装置２００１本体部（この場合、酸素出口７）に解除手段を備えてあるが、カプラ１３に解除手段を備えていても構わない。本解除手段により、鼻カニューラや延長チューブに引火した炎の医療用酸素供給装置２００１本体部への延焼を未然に防ぐことができる。 <Description of configuration of release means>
One embodiment of the release means for automatically releasing the coupler 13 will be described. FIG. 9 shows before release of the release means for automatically releasing the coupler 13, and FIG. 10 shows after release of the release means for automatically releasing the coupler 13. As described above, the coupler 13 is engaged with the stepped portion 71 formed at the oxygen outlet 7 in an airtight state (not shown). As an embodiment of the release means, the compression spring 72, the heater 73, and the bimetal 74 are included in the release means, but are not limited thereto. As shown in FIG. 9, the compression spring 72 is provided in the oxygen outlet 7 in a compressed state by a bimetal 74 having an L shape. The bimetal 74 has a metal plate 741 (for example, Invar) having a low coefficient of thermal expansion and a metal plate 742 (for example, an alloy of Fe and Ni added with Mn, Cr, Cu, Mg, etc.) having a high coefficient of thermal expansion. ). The bimetal has a property of changing the way of bending according to temperature change. When heat is applied, the bimetal 74 bends with the metal plate 741 having a small thermal expansion coefficient on the inside and the metal plate 742 having a large thermal expansion coefficient on the outside. Utilizing this property, by deforming the bimetal 74, the compressed compression spring 72 is released and the coupler 13 is automatically released (FIG. 10). Since the heater 73 serves to apply heat to the bimetal 74 and is connected to the central control unit 200, temperature adjustment and control can be performed by the central control unit 200. As a result, the central control unit 200 controls the heating of the heater to automatically release the coupler 13. Even if the central control unit 200 does not heat the heater when a flame is generated, the bimetal 74 is heated by the flame ignited in the nasal cannula or the extension tube, so the coupler 13 is automatically released. In this embodiment, the medical oxygen supply apparatus 2001 main body (in this case, the oxygen outlet 7) is provided with the release means, but the coupler 13 may be provided with the release means. By this releasing means, it is possible to prevent the flame spread to the medical oxygen supply device 2001 main body from being ignited in the nasal cannula or the extension tube.
　図１１は、赤外線センサ２２２１により医療用酸素供給装置２００１及び/又は装置周辺の炎を検知して、コンプレッサ１０の動作と、濃縮酸素の供給を停止させ、酸素出口７とカプラ１３との接続が自動解除され、音声ガイドを行う動作説明のフローチャートである。
　はじめに医療用酸素供給装置１が起動されるとステップＳ２１０に進み、赤外線センサ２２２１の計測が行われる。赤外線センサ２２２１は、連続的又は消費電力を考慮して５分毎など断続的に装置及び/又は装置周辺の熱源を計測し、炎を検知することができ、ステップＳ２１１において、検出した異常な温度上昇が予め設定した温度例えば６０℃を超えたとき、ステップＳ２１２に進み、赤外線センサ２２２１から温度異常を知らせる電気信号を受けた中央制御部２００は、モータ制御部２０１にコンプレッサ１０の動作を停止させ、流量制御部２０２に濃縮酸素の供給を停止させ、酸素出口７とカプラ１３との接続を自動解除させる（ステップＳ２１２）。この後、ステップＳ２１３において音声ガイドを行い、処理を終了する。一方、ステップＳ２１１において、赤外線センサ２２２１の検出した異常な温度上昇が６０℃に満たないとき、ステップＳ２１０に戻り、上記のステップＳ２１０から繰り返す。ステップＳ２１２とステップＳ２１３において、コンプレッサ１０の動作と濃縮酸素の供給が停止され、酸素出口７とカプラ１３との接続が自動解除され、音声ガイドが実行されれば目的は達成されるので、ステップＳ２１２とステップＳ２１３の順序が逆であっても、又同時に実行されてもよい。また、上記のような赤外線センサによる温度測定以外にも、炎特有のＣＯ２共鳴放射や揺らぐ（ちらつく）現象などから炎を検知する赤外線強度測定により、異常な温度上昇を検知してもよい。その場合、ステップＳ２１１以外は赤外線センサによる温度測定と同様なフローチャート（不図示）となり、ＣＯ２共鳴放射による4.4μmの固有の波長を検知または揺らぐ現象による1～15Hzの間に集中した変動周波数を検知することで、炎であるかどうかを判定する（ステップＳ２１１）。ステップＳ２１１において、炎であると判定した場合、ステップＳ２１２へ進み、炎ではないと判定した場合、ステップＳ２１０に戻り、上記のステップＳ２１０から繰り返す。さらに、酸素出口７に不図示の閉鎖弁を配置することで、異常な温度上昇を検知したら直ぐに酸素出口７を閉鎖し、酸素供給を停止することができる（ステップＳ２１２或いはステップＳ２１３）。 In FIG. 11, the infrared sensor 2221 detects the medical oxygen supply apparatus 2001 and / or flame around the apparatus, stops the operation of the compressor 10 and the supply of concentrated oxygen, and the connection between the oxygen outlet 7 and the coupler 13 is performed. It is a flowchart of operation | movement description which is cancelled | released automatically and performs voice guidance.
First, when the medical oxygen supply device 1 is activated, the process proceeds to step S210, and the infrared sensor 2221 is measured. The infrared sensor 2221 can measure the device and / or the heat source around the device intermittently, for example, every 5 minutes in consideration of power consumption or continuously, and detect the flame. In step S211, the abnormal temperature detected. When the increase exceeds a preset temperature, for example, 60 ° C., the process proceeds to step S212, and the central control unit 200 that receives the electrical signal notifying the temperature abnormality from the infrared sensor 2221 causes the motor control unit 201 to stop the operation of the compressor 10. Then, the flow rate control unit 202 stops the supply of concentrated oxygen, and the connection between the oxygen outlet 7 and the coupler 13 is automatically released (step S212). Thereafter, voice guidance is performed in step S213, and the process is terminated. On the other hand, in step S211, when the abnormal temperature increase detected by the infrared sensor 2221 is less than 60 ° C., the process returns to step S210 and is repeated from step S210. In steps S212 and S213, if the operation of the compressor 10 and the supply of concentrated oxygen are stopped, the connection between the oxygen outlet 7 and the coupler 13 is automatically released, and voice guidance is executed, the objective is achieved. And the order of step S213 may be reversed or may be executed simultaneously. Besides temperature measurement by the infrared sensor as described above also, the flame-specific CO 2 resonance radiation and fluctuates (flicker) phenomenon by infrared intensity measurement for detecting a flame from such as it may detect an abnormal rise in temperature. In that case, except for step S211, the flow chart (not shown) is the same as the temperature measurement by the infrared sensor, and the fluctuation frequency concentrated between 1 and 15Hz due to the phenomenon of detecting or fluctuating the inherent wavelength of 4.4μm due to CO 2 resonance radiation. By detecting, it is determined whether it is a flame (step S211). If it is determined in step S211 that it is a flame, the process proceeds to step S212. If it is determined that the flame is not a flame, the process returns to step S210 and is repeated from step S210. Furthermore, by disposing a closing valve (not shown) at the oxygen outlet 7, the oxygen outlet 7 can be closed immediately after detecting an abnormal temperature rise, and the oxygen supply can be stopped (step S212 or step S213).

Is stopped, the supply of concentrated oxygen is stopped in the flow rate control unit 202, and the connection between the oxygen outlet 7 and the coupler 13 is automatically released (step S212). Thereafter, voice guidance is performed in step S213, and the process is terminated. On the other hand, in step S211, when the abnormal temperature increase detected by the infrared sensor 3221 is less than 60 ° C., the process returns to step S210 and is repeated from step S210.

The central control unit 200 sends an electric signal for stopping the operation of the compressor 10 to the motor control unit 201 and the flow control unit 202 closes the demand valve 117 by the electric signal informing the presence / absence of the flame. An electric signal for stopping the supply of the gas is sent to the releasing means of the coupler 13 for releasing the connection between the coupler 13 and the oxygen outlet 7. At this time, the release means of the coupler 13 only has to automatically release the connection between the oxygen outlet 7 and the coupler 13 under the control of the central control unit 200. For example, the elastic means of an elastic body such as a compression spring is used. Any means such as automatic release or solenoid type automatic release using repulsion due to electromagnetic force may be used. An embodiment of the releasing means for the coupler 13 of the present invention will be described later. As a flame detection method of the ultraviolet sensor 4221, for example, a flame burned with hydrogen emits light having a strong ultraviolet wavelength in the range of 185 to 260 nm. Thus, the presence or absence of a flame is determined.
＜解除手段の構成の説明＞
　カプラ１３を自動で解除する解除手段の一実施形態についての説明は、第３の実施の形態の＜解除手段の構成の説明＞と同様である。 <Description of configuration of release means>
An explanation of one embodiment of the release means for automatically releasing the coupler 13 is the same as <Description of Configuration of Release Means> in the third embodiment.
　図１６は、紫外線センサ４２２１により医療用酸素供給装置４００１及び/又は装置周辺の炎を検知して、コンプレッサ１０の動作と、濃縮酸素の供給を停止させ、酸素出口７とカプラ１３との接続が自動解除され、音声ガイドを行う動作説明のフローチャートである。はじめに医療用酸素供給装置４００１が起動されるとステップＳ３１０に進み、紫外線センサ４２２１の炎の有無判定が行われる。紫外線センサ４２２１は、連続的又は消費電力を考慮して５分毎など断続的に装置及び/又は装置周辺の炎の有無を判定し、炎の検知をすることができ、ステップＳ３１１において、炎が存在したとき、ステップＳ３１２に進み、紫外線センサ４２２１から炎の存在を検知した中央制御部２００は、モータ制御部２０１にコンプレッサ１０の動作を停止させ、流量制御部２０２に濃縮酸素の供給を停止させ、酸素出口７とカプラ１３との接続を自動解除させる（ステップＳ３１２）。この後、ステップＳ３１３において音声ガイドを行い、処理を終了する。一方、ステップＳ３１１において、炎を検知しないとき、ステップＳ３１０に戻り、上記のステップＳ３１０から繰り返す。ステップＳ３１２とステップＳ３１３において、コンプレッサ１０の動作と濃縮酸素の供給が停止され、酸素出口７とカプラ１３との接続を自動解除され、音声ガイドが実行されれば目的は達成されるので、ステップＳ３１２とステップＳ３１３の順序が逆であっても、又同時に実行されてもよい。さらに、酸素出口７に不図示の閉鎖弁を配置することで、異常な温度上昇を検知したら直ぐに酸素出口７を閉鎖し、酸素供給を停止することができる（ステップＳ３１２或いはステップＳ３１３）。 In FIG. 16, the ultraviolet sensor 4221 detects a medical oxygen supply device 4001 and / or a flame around the device, stops the operation of the compressor 10 and the supply of concentrated oxygen, and the connection between the oxygen outlet 7 and the coupler 13 is performed. It is a flowchart of operation | movement description which is cancelled | released automatically and performs voice guidance. First, when the medical oxygen supply device 4001 is activated, the process proceeds to step S310, and the presence / absence of flame of the ultraviolet sensor 4221 is determined. The ultraviolet sensor 4221 can detect the flame by continuously determining the presence or absence of a flame around the apparatus and / or the apparatus, for example, every 5 minutes in consideration of power consumption, and in step S311, the flame is detected. When present, the process proceeds to step S312, and the central control unit 200 that has detected the presence of flame from the ultraviolet sensor 4221 causes the motor control unit 201 to stop the operation of the compressor 10 and causes the flow rate control unit 202 to stop the supply of concentrated oxygen. Then, the connection between the oxygen outlet 7 and the coupler 13 is automatically released (step S312). Thereafter, voice guidance is performed in step S313, and the process is terminated. On the other hand, when no flame is detected in step S311, the process returns to step S310 and is repeated from step S310. In steps S312 and S313, if the operation of the compressor 10 and the supply of concentrated oxygen are stopped, the connection between the oxygen outlet 7 and the coupler 13 is automatically released, and voice guidance is executed, the objective is achieved. And the order of step S313 may be reversed or may be executed simultaneously. Furthermore, by disposing a closing valve (not shown) at the oxygen outlet 7, the oxygen outlet 7 can be closed as soon as an abnormal temperature rise is detected, and the oxygen supply can be stopped (step S 312 or step S 313).
