胞内のガス交換を活発にする呼吸刺激性を有している。2. Description of the Related Art Oxygen is indispensable to the life of living cells. In humans, arterial blood contains 19-20% by volume oxygen (O 2 ) and 48-50% by volume carbon dioxide (CO 2 ), and venous blood contains 12-14% by volume oxygen and 56-58% by volume. Containing carbon dioxide, venous blood exchanges gas with the air in the alveoli. If, for some reason, the oxygen in the air cannot be taken up sufficiently, or if the arterial blood cannot carry the amount of oxygen required by living tissue, or if the activity of cellular oxidase is impaired, Oxygen deficiency (anoxia) causes the function of the body to be impaired. In particular, the central nervous system and heart respond sensitively to lack of oxygen. Therefore, in such a case, it is necessary to artificially supply oxygen. Further, as mentioned above, carbon dioxide is usually dissolved in the arterial blood at 48 to 50% by volume.
An autonomic mechanism works to stimulate the respiratory center and reduce the amount of carbon dioxide. As a result, breathing becomes faster and larger, which promotes gas exchange in the alveoli. When breathing volume is several times higher than usual, it causes vomiting, loss of thinking, and increased blood pressure. It also affects the vascular center of the brain and causes systemic vasoconstriction, but cerebral blood vessels expand to increase blood flow. Heart rate and stimulus conduction are suppressed, but cardiac output is increased. On the other hand, when the amount of carbon dioxide is decreased, the respiratory rate is decreased, and peripheral vasodilation and accompanying hypotension, rapid heartbeat and decreased cardiac output occur. As the respiratory rate decreases, carbon dioxide accumulates in the body, and the stimulation of the respiratory center accelerates breathing again. Thus, carbon dioxide has a respiratory stimulant that stimulates the respiratory center to increase the number of respirations and activates gas exchange in the alveoli.

いられている。このように、呼吸刺激を考慮した場合に
は、純酸素の吸入よりも、二酸化炭素を混合した酸素の
吸入の方が望ましい。When hypoxemia in high mountains, dyspnea attacks caused by stress (hyperventilation), and induction of ether anesthesia, carbon dioxide deficiency reduces the excitability of the respiratory center. Since breathing autonomy does not occur when there is, it is necessary to give both carbon dioxide and oxygen to make breathing. Usually, a gas in which 5 to 10% by volume of carbon dioxide is mixed with pure oxygen is used. Thus, in consideration of respiratory stimulation, inhalation of oxygen mixed with carbon dioxide is preferable to inhalation of pure oxygen.

がある。[0004] Conventionally, when inhaling oxygen mixed with carbon dioxide in consideration of respiratory stimulus at the time of oxygen inhalation, in equipment such as a hospital, a large fixed oxygen cylinder or carbon dioxide cylinder is used. Gas is sent to various places through piping,
The gas mixed at a predetermined mixing ratio is inhaled by the patient. In addition, there is a device that is easily transported by mounting an oxygen cylinder or a carbon dioxide cylinder on a truck or the like in order to support emergency medical care such as mounting on an ambulance. On the other hand, oxygen cans in which light cans are filled with pure oxygen (100% O 2 ) are commercially available as oxygen cans that can be easily inhaled in daily life. This oxygen can easily inhales oxygen and is effective in recovering from fatigue and refreshing after sports and climbing.

However, it was practically impossible to use this gas easily. In addition, the oxygen can allows easy oxygen inhalation, which helps to recover from fatigue after sports or when climbing mountains.
Although it is effective for refreshing, carbon dioxide in arterial blood decreases (about 20% by volume) as in dyspnea (hyperventilation), and the symptoms may worsen.

Oxygen can be easily inhaled, and oxygen can be replenished while activating breathing as compared with conventional pure oxygen inhalation, so the effect of replenishing oxygen is high. It can also be used for the emergency treatment of dyspnea symptoms (hyperventilation) accompanied by a decrease in blood CO 2 concentration, which is ineffective with conventional pure oxygen inhalation. Further, it is filled with a gas in which carbon dioxide and oxygen are mixed in advance at a predetermined composition ratio, and since the composition ratio of carbon dioxide and oxygen is constant regardless of the time of use, safety is high. Also, by attaching a suction mask to the injection nozzle, it is possible to suck the mixed gas without waste,
In addition, the mixed gas jetted from the jet nozzle and air are mixed in the mask so that the oxygen concentration at the time of inhalation is 25 to 70% by volume.
By providing the air introduction hole for the purpose, it is possible to prevent unpleasant symptoms (numbness of limbs, decrease in vital capacity, joint pain, etc.) that occur when a high concentration of oxygen is inhaled for a long time.

As the mixed gas 4, a gas having a composition of 5 to 10% by volume of carbon dioxide and the balance of oxygen is used. When the amount of carbon dioxide is less than 5% by volume, when the mixed gas 4 is inhaled, the respiratory stimulating action of carbon dioxide cannot be sufficiently obtained, and the same as inhalation of pure oxygen is obtained.
Further, if the amount of carbon dioxide exceeds 10% by volume, when the user inhales except when he / she has difficulty breathing, the respiratory stimulating action of carbon dioxide may be strongly exerted to cause discomfort, which is not preferable. It should be noted that a mixed gas 4 having a composition of 10 to 20% by volume of carbon dioxide and the balance of oxygen may be filled and used as a dedicated gas especially for dyspnea such as hyperventilation.
