Abstract

PURPOSE:To provide a hermetically sealed oxygen can which is useful for the emer gency countermeasures against the human respiratory oxygen defficiency when it occurs by generating oxygen in a portable can filled with water through charging the can with an oxygen generating agent contg. Na2CO3.3/2H2O2 as the principal ingredient, then hermetically sealing the can and opening it and releasing the oxygen at the time of needing oxygen. CONSTITUTION:As an example of the blending formulations of the oxygen generating agent to be enclosed in the hermetically sealed can, an agent contg. 42.73% Na2CO3.3/2 H2O2, 4.27% MnO2, 47.43% CaH2P2O7 and 5.57% expanded graphite is formed into its tablets by using a tablet machine. A portable, comparatively small sized can made of aluminum, etc., is filled with water to about 60% level of its inner volume and then charged with the oxygen generating agent tablets. When the generation of oxygen is started, the can is hermetically sealed to use as the oxygen can. When an emergency of the oxygen defficiency causing abnormal conditions of the human body occurs, oxygen is immediately released by opening the can and subsequently generated continuously over a considerably long period of time to protect the safe human respiration. The blending formulation consisting of 65.54% Na2CO3.3/2H2O2, 25.50% C4H6O4 and 8.96% soluble starch is an example of the formulations which form no residue.

Description

Detailed Description of the Invention

[0001]

[Industrial application] Oxygen sealing that is effective in easily replenishing oxygen by opening the can when urgently needing oxygen inhalation, such as mountain climbing, extreme exercise, and other oxygen deficiency conditions. Regarding cans.

[0002]

2. Description of the Related Art When it is urgently necessary to inhale oxygen, it is used to open the oxygen cylinder to release oxygen and use it. It is necessary to increase the compression rate, which is inconvenient to carry and handle.

[0003]

SUMMARY OF THE INVENTION In view of the conventional circumstances, it is an object of the present invention to provide an oxygen generating container which is easy to carry and handle and which can continue to release oxygen for a long time.

[0004]

By introducing an oxygen generating agent to about 60% in the main agent of ^{_{NaCO 3 3/2 H 2 O}} 2 in a water-filled portable possible aluminum cans having an inner volume of [SUMMARY OF] oxygen A sealed can of oxygen that can be generated and sealed to release oxygen as needed.

[0005]

[Function] An easy-to-carry oxygen-sealed can that stores a drug that generates oxygen by dissociation and decomposition in a sealed can, and opens the can in an emergency to generate oxygen for a long time.

EXAMPLES canned the oxygen of about 60% equivalent amount of water of the internal volume of the can readily sealed aluminum leave earlier Dzu injected, this in a ^{_{Na 2 CO 3 3/2 H}} 2 O 2 When this can is sealed when an oxygen generating agent consisting of organic acids such as succinic acid and an excipient is added and the reaction begins, the oxygen generated in the can is hardly dissolved in water, so it is mainly the void part of the aluminum can. Are accumulated under pressure. The inner surface of the can is preferably anticorrosion coated. The solubility of oxygen in water follows the common law for gases and is as follows.

A) Solubility under pressure When a gas dissolves in water, it is related not only to the temperature but also to the applied pressure. According to Henry's law, the solubility of a gas is that the mass of a gas dissolved in water of a constant volume and a constant temperature is proportional to the pressure of the gas in equilibrium with that water. The higher the partial pressure, the faster the dissolution rate and the higher the solubility. However, in water at a constant temperature, it does not dissolve above saturation.

(B) Temperature and solubility When a solid dissolves in water, its solubility usually increases with increasing temperature, whereas that of gas decreases with increasing temperature and conversely increases with decreasing temperature. . Therefore, as for oxygen, if the water temperature is low, the amount of dissolved oxygen will increase.
The relationship between oxygen and water in a sealed can follows the above rules. Secondly, it is often necessary to urgently supplement oxygen in a situation where the human body is deficient in oxygen.

The amount of respiration to maintain human life is blood 10
With an air volume that requires about 20 mL of oxygen per 0 mL, it is an average for an adult to produce about 3000 KcaL of energy per day.
It is said that 600L (normal temperature and normal pressure) of oxygen is required. Therefore, per hour (600 L) / 24 = 25 L, and per minute (25 L) / 60 = 416 mL. Next, the abnormal condition of the human body due to the decrease in oxygen concentration is as follows.

[Table 1] Compounding of the oxygen generating agent sealed in sealing can of the present invention is ^{_{Na 2 CO 3 3/2 H}} 2 O 2 42.73% MnO 2 4.27 CaH 2 P 2 O 7 47.43 expanded graphite 5.57 above formulation The oxygen generating agent that was made into a tablet by applying the above drug to a tablet machine was filled with water before filling about 60% of the internal volume of a relatively small portable can such as aluminum, and oxygen was begun to be generated. Seal the cod can to make a can of oxygen. If this can is opened in an emergency when an oxygen deficiency that causes abnormalities in the human body is opened, oxygen is immediately released and oxygen is subsequently generated, which is useful for maintaining breathing safety for a considerably long time.

Although the generator solution is neutralized in the above oxygen generating agent, since a residue is generated, the oxygen generating agent according to the following formulation does not generate a residue and becomes PH 6 to 7, which is easily discarded. Its formulation is convenient to handle if the tablets at ^{_{NaCO 3 3/2 H 2 O}} 2 65.54% C 4 H 6 O 4 25.50 Soluble starch 8.96 in the same tableting machine.
If the sealing can is a double lid and the oxygen generating agent is housed between the lids and the oxygen generating agent falls into the water immediately before use, the deterioration of the agent is small and the effect can be maintained for a long time. .

[0012]

As described above, this oxygen-sealed can is effective as an emergency measure in the case of oxygen deficiency of human breathing, and after vigorous exercise,
It is effective for mountain climbing, in tanks where there is a risk of oxygen deficiency, in fires, etc., which can be easily used in an emergency when oxygen needs to be supplied promptly.
