Description
本発明は、酸素吸入方法及び酸素吸入具に係り、特に、体内の血液を効率よく冷却するための酸素吸入方法及び酸素吸入具に関する。ここで「酸素吸入」とは、高濃度酸素の吸入でもよいが、酸素を含む空気等の気体の吸入でもよく、その範囲内であれば酸素濃度は問わない。 The present invention relates to an oxygen inhalation method and oxygen inhalation device, and in particular to an oxygen inhalation method and oxygen inhalation device for efficiently cooling blood in the body. Here, "oxygen inhalation" can mean the inhalation of high-concentration oxygen, or the inhalation of a gas such as air that contains oxygen, and the oxygen concentration does not matter as long as it is within that range.
毎年、熱中症が大きな問題になっている。熱中症は、医学的には身体の温度変化に起因して発症し、呼吸困難などを伴って重篤化することが知られている。病院では、酸素吸入により処置を行うが、その際、血中酸素（酸素飽和度ＳｐＯ２）の数値指標が重要な判断基準とされている。 Heat stroke is becoming a big problem every year. Medically, heat stroke is caused by a change in body temperature, and it is known that it can become serious due to breathing difficulties. In hospitals, patients are treated by oxygen inhalation, and the numerical index of blood oxygen (oxygen saturation SpO2 ) is an important criterion for making judgments.
一方、本願発明者は、熱中症への対処にあたり、酸素吸入器から供給される酸素の温度が重要であることを見出した。一般的に、酸素吸入器から供給される酸素の温度は、通常３７度前後に加温加湿の設定がなされている。しかし、熱中症の場合、身体の温度が関係するため、酸素吸入器から供給する酸素の温度をコントロールすべきである。 Meanwhile, the inventors of the present application have discovered that the temperature of the oxygen supplied from an oxygen inhaler is important when dealing with heat stroke. In general, the temperature of oxygen supplied from an oxygen inhaler is usually set to around 37 degrees with heating and humidification. However, in the case of heat stroke, the body temperature is involved, so the temperature of the oxygen supplied from the oxygen inhaler should be controlled.
身体を冷やす場合、現在は、大きい血管がある脇などを冷やすことが推奨されている。しかし、実際は毛細血管が密集する肺で血液は冷やされる。熱中症は、身体温度よりも熱い外気を吸い込むことで生じる。入浴で４０度に身体が温められても、露天風呂では熱中症になりづらいのは、外気が身体温度よりも低いことが多いためだと考えられる。この機序は、呼吸器専門医に確認したところ、理論的に正しいということである。ここで、本願の出願人は、上記に関連する先行技術文献の存在を知らない。 When cooling the body, it is currently recommended to cool areas such as the armpits where large blood vessels are located. However, in reality, blood is cooled in the lungs where capillaries are densely concentrated. Heat stroke is caused by inhaling outside air that is hotter than the body temperature. Even if the body is warmed to 40 degrees in a bath, it is thought that heat stroke is less likely to occur in an open-air bath because the outside air is often colder than the body temperature. This mechanism was confirmed by a respiratory specialist and is found to be theoretically correct. Here, the applicant of the present application is not aware of the existence of prior art documents related to the above.
本発明は、上記の知見に基づき、酸素吸入具から肺に供給する酸素の温度をコントロールすることで、体内の血液を効率よく冷却し、熱中症等の症状の改善をサポートすることを課題とする。 Based on the above findings, the present invention aims to efficiently cool blood in the body and help improve symptoms such as heat stroke by controlling the temperature of oxygen supplied to the lungs from an oxygen inhaler.
上記課題を解決するため、本発明の酸素吸入方法は、酸素の温度を外気温より低い１０度から３０度の範囲に冷却する冷却ステップと、当該冷却した酸素を患者の肺に吸入させる吸入ステップとを備えている。 To solve the above problems, the oxygen inhalation method of the present invention includes a cooling step in which the temperature of the oxygen is cooled to a range of 10 to 30 degrees Celsius, which is lower than the outside air temperature, and an inhalation step in which the cooled oxygen is inhaled into the patient's lungs.
また、本発明の酸素吸入具は、上記の酸素吸入方法に用いる酸素吸入具であって、外気温より低い１０度から３０度の範囲に冷却された酸素入りボンベと、当該酸素入りボンベの酸素を患者が吸入する吸入口とを備えている。ここで、「酸素入り」とは、高濃度酸素の封入でもよいが、酸素を含む空気等の気体の封入でもよく、その範囲内であれば酸素濃度は問わない。 The oxygen inhaler of the present invention is an oxygen inhaler used in the above-mentioned oxygen inhalation method, and is equipped with an oxygen cylinder cooled to a temperature between 10 and 30 degrees Celsius, which is lower than the outside temperature, and an inhalation port through which the patient inhales the oxygen from the oxygen cylinder. Here, "oxygen-containing" may mean high-concentration oxygen or a gas such as air that contains oxygen, and the oxygen concentration does not matter as long as it is within that range.
本発明によれば、酸素吸入具から肺に供給する酸素の温度をコントロールすることで、体内の血液を効率よく冷却し、熱中症等の症状の改善をサポートすることができる。 According to the present invention, by controlling the temperature of the oxygen supplied to the lungs from an oxygen inhaler, it is possible to efficiently cool the blood in the body and help improve symptoms such as heat stroke.
［第１実施形態］
以下、本発明の第１実施形態を図１を参照して説明する。
[First embodiment]
A first embodiment of the present invention will now be described with reference to FIG.
酸素吸入具（酸素吸入器）が、体内に供給する酸素の温度を設定する機能を有している場合を説明する。当該温度を設定する機能により、体内に供給する酸素の温度を外気温（熱中症を生じた気温）よりも低い温度に設定する（ステップＳ１）。例えば、１０度から３０度の範囲で設定する。設定温度は、温度の設定機能にも依存するが、例えば、１０度から３０度の範囲で０．５度刻みの温度を選択的に取り得る。 The following describes a case where an oxygen inhaler (oxygen inhaler) has a function for setting the temperature of oxygen supplied to the body. The temperature setting function sets the temperature of oxygen supplied to the body to a temperature lower than the outside air temperature (the air temperature at which heat stroke occurs) (step S1). For example, it is set to a range of 10 to 30 degrees. The set temperature depends on the temperature setting function, but for example, it can be selected to be a temperature in 0.5 degree increments in the range of 10 to 30 degrees.
そして、酸素吸入具を作動させ、外気温よりも低い温度に設定した酸素を肺に供給する（ステップＳ２）。これにより、毛細血管が密集する肺から体内の血液を冷却し、熱中症の改善を図る。 Then, the oxygen inhaler is activated and oxygen set to a temperature lower than the outside air temperature is supplied to the lungs (step S2). This cools the blood in the body from the lungs, where capillaries are densely concentrated, and aims to improve heat stroke.
［第２実施形態］
酸素吸入具は、コンビニエンスストア等で市販されている酸素入りボンベ（酸素缶や空気缶）でもよい。この場合、酸素の冷却方法は種々考えられるが（後述）、酸素入りボンベの温度は外気温（熱中症を生じた気温）よりも低い温度に調節する（ステップＳ１）。例えば、１０度から３０度の範囲で調節する。調整温度は、冷却方法に依存するが、例えば、１０度から３０度の範囲で０．５度刻みの温度を選択的に取り得る。
[Second embodiment]
The oxygen inhaler may be an oxygen cylinder (oxygen can or air can) that is commercially available at convenience stores, etc. In this case, various methods for cooling the oxygen are possible (described later), but the temperature of the oxygen cylinder is adjusted to a temperature lower than the outside air temperature (the air temperature at which heat stroke occurred) (step S1). For example, it is adjusted to a range of 10 to 30 degrees. The adjusted temperature depends on the cooling method, but for example, it can be selected to a temperature in 0.5 degree increments within the range of 10 to 30 degrees.
そして、酸素入りボンベを開弁し、外気温よりも低い温度に調節された酸素を肺に供給する（ステップＳ２）。これにより、毛細血管が密集する肺から体内の血液を冷却し、熱中症の改善を図る。 Then, the valve of the oxygen tank is opened, and oxygen adjusted to a temperature lower than the outside air temperature is supplied to the lungs (step S2). This cools the blood in the body from the lungs, where capillaries are densely concentrated, and aims to improve heat stroke.
［第３実施形態］
第２実施形態において、酸素入りボンベは、コンビニエンスストア等の販売店で、冷却装置により販売前に冷却されていてもよい。又は、酸素入りボンベは、購入後に、冷却装置により冷却されてもよい。
[Third embodiment]
In the second embodiment, the oxygen cylinder may be cooled by a cooling device at a store such as a convenience store before being sold, or the oxygen cylinder may be cooled by a cooling device after purchase.
［第４実施形態］
第２実施形態において、酸素入りボンベは、冷却機能を有するカバーで覆われることにより、冷却されてもよい。冷却機能を有するカバーとしては、図２に示すように、冷却機能を有するジェル１（冷却剤）を封入したカバー２が考えられる。また、ジェル１に変えて、冷却した水、氷又は氷水を封入するカバー２でもよい。
[Fourth embodiment]
In the second embodiment, the oxygen cylinder may be cooled by being covered with a cover having a cooling function. As a cover having a cooling function, a
［第５実施形態］
第２から第４の各実施形態において、酸素入りボンベは、使い捨てに限らず、酸素を再度充填して再利用が可能な構造でもよい。図２に示す酸素入りボンベ３は、吸入口部分４がボンベ本体から脱着可能となっている。このように吸入口部分を脱着可能とした酸素缶は、例えば、特開２０００－３３１２０号公報等に開示されている。ボンベ本体から吸入口部分４を取り外し、店舗で酸素入りボンベ３に酸素を再度充填するようにしてもよい。このとき、酸素の温度を予め外気温より低い１０度から３０度の範囲に調節してから酸素入りボンベ３に充填してもよい。
[Fifth embodiment]
In each of the second to fourth embodiments, the oxygen cylinder is not limited to being disposable, but may be structured so as to be refilled with oxygen and reusable. In the
［第６実施形態］
本発明の第６実施形態を図３に示す。筒状の送風体５は、一端部に吸気ファン６を備えると共に、他端部に吸入口７を備え、吸気ファン６から吸い込んだ空気を吸入口７に案内するようになっている。送風体５は、吸気ファン６から吸入口７に至るまでの通路に、冷却ジェルパック等の冷却体８を挿抜可能な取付部９を備えている。冷却体８に封入される冷却剤は、冷却したジェル、水、氷又は氷水でもよい。
Sixth Embodiment
A sixth embodiment of the present invention is shown in Fig. 3. A
利用者は、コンビニエンスストア等で冷却ジェルパック等の冷却体８を購入し、冷却体８を送風体５の取付部９に取り付ける。装置を稼働状態に設定すると、吸気ファン６から吸い込まれた空気が冷却体８の作用により送風体５を通過する間に熱を奪われ、吸入口７に至る。利用者は、吸入口７に鼻、口を寄せて空気を吸い込むと、吸気ファン６から吸入された外気よりも低い温度の空気を肺に送ることができる。これにより、毛細血管が密集する肺から体内の血液を冷却することが可能であり、熱中症の改善が可能となる。

The scope of the present invention is the scope of the invention described in the claims. In each embodiment, "oxygen" may refer to high-concentration oxygen or oxygen contained in a gas such as air, and the oxygen concentration does not matter within that range. The present invention is expected to be effective in supporting the treatment of not only heat stroke but also lung diseases.
