Description

Technical Field

[0001] The present invention relates to the technical field of medical rescue, and in particular to providing oxygen for people with altitude sickness or for emergency treatment or safety assurance in toxic areas or confined spaces where oxygen cannot be produced due to power supply, and providing a required and portable micro-sized liquid oxygen storage and supply device. Background Art

[0002] With the increase of retired elderly people, more and more people are traveling to the Yunnan-Guizhou Plateau or the Qinghai-Tibet Plateau. Since everyone's physical condition or physical condition varies greatly, the degree of adaptation to the air on the plateau is different, and the slightest negligence may endanger life. Therefore, it is necessary to have oxygen storage and supply equipment to meet the needs of emergency treatment. At present, when traveling in plateau areas, "Oxygen Ankang brand portable oxygen respirator" and similar products are generally used. The capacity of each bottle is about 450 ml. Because of the small storage capacity and low pressure, it can only be inhaled for about 15-25 seconds. If the altitude reaction is severe, it is far from enough; and the 40-liter standard medical oxygen cylinder weighs about 55 kilograms and is 150 centimeters high, which is particularly bulky; even a 10-liter small oxygen cylinder weighs 14 kilograms and is 45 centimeters high. It is not convenient for oxygen inhalers to carry, nor can it be operated by themselves, and it is very troublesome to use. Therefore, people are eager to have a convenient and lightweight oxygen supply device with a certain storage capacity to ensure the first aid effect and meet the needs of altitude sickness. People working in small spaces or toxic places also hope to have lightweight oxygen supply equipment to ensure safe production. In addition, there are more than 200 million elderly people over the age of 70 in my country. When these people go out temporarily or take a car, they hope to have an oxygen supply device that is particularly light, easy to operate, does not need to be plugged in, and can provide sufficient oxygen with them to ensure first aid in case of hypoxia. Summary of the invention

[0003] The purpose of the present invention is to design a miniature oxygen storage and supply device that is easy to carry, easy to operate, has advanced performance, novel structure, and is economical and practical in response to the above-mentioned actual situation, so as to provide patients with sufficient oxygen when there is no oxygen supply facility, or to provide people with the convenience of oxygen inhalation when oxygen supplement is needed in the absence of electricity (toxic occasions or confined spaces, in the wild or on the road), so as to improve the quality of life, ensure life safety, and reduce the occurrence of accidents.

[0004] To achieve the above-mentioned purpose, the present invention is implemented by adopting the following effective and sophisticated design and technical solutions: a portable oxygen supply bottle for eliminating altitude sickness, which is composed of a sheath, a bottle body, a bolt assembly, a bottle cap, a safety valve, a self-unloading valve seat, a cryogenic working fluid valve body, a sealing ring, a spare vaporizer, a spring, a pressure plate and a sealing gasket. The connection relationship between the various parts of the portable oxygen supply bottle for eliminating altitude sickness is as follows: the sheath of the oxygen supply bottle can be placed stably on a table or on the ground, and can also be carried on the shoulder through the ear holes on the upper part of the sling. The bottle body is made of two layers, inner and outer, welded by strict and meticulous argon arc welding. First, dozens of layers of high-efficiency heat-reflecting layers are tightly wrapped around the outside of the inner layer, and then the inner and outer layers are welded together by argon arc welding. After strict non-destructive testing, it is determined to be a qualified product, so that it has a highly efficient ultra-low temperature effect. A vacuum joint is welded on the bottom of the outer layer of the bottle body. After the bottle body is vacuumed, the ultra-low temperature effect is more stable and lasting; the bolt assembly is used to connect the bottle body and the bottle cap, and the bolt assembly is installed. The whole valve is installed at the corresponding position on the bottle cap, the self-pressure relief valve seat is welded in the middle of the bottle cap, and the cryogenic working medium valve body is installed in the self-pressure relief valve seat; when the pressure in the bottle exceeds the set pressure of the safety valve, and the discharge volume of the safety valve cannot reduce the pressure in the bottle, the special design structure of the self-pressure relief valve seat allows the oxygen in the bottle to pass through the 6 φ4 holes on the self-pressure relief valve seat to automatically lift the sealing gasket and the pressure plate on the self-pressure relief valve seat, and compress the spring to quickly discharge the oxygen in the bottle to reduce the pressure in the bottle. When the pressure drops to the set pressure, it can be automatically closed by the elastic force of the spring, thus ensuring the safety of the oxygen supply bottle; the bottle cap is screwed in The plug assembly is connected with the sealing ring and the bottle body. The bottle cap also adopts an inner and outer two-layer structure, which is welded by meticulous argon arc welding and rigorous non-destructive testing. After being judged as qualified products, the valve seat of the safety valve and the self-unloading valve seat are welded to specific positions on the bottle cap respectively, and dozens of layers of special heat reflection layers are tightly stacked on the inside of the outer layer of the bottle cap. The inner and outer layers are welded together by argon arc welding. After non-destructive testing, it is qualified products, so that it can have better ultra-low temperature effect; during assembly, the safety valve and the cryogenic working fluid valve body are screwed into their respective valve seats respectively; the rotating valve core on the cryogenic working fluid valve body is used to adjust the inlet of liquid oxygen (or outlet of oxygen) Speed, there is a liquid inlet (gas outlet) joint on the side of the cryogenic working fluid valve body to connect with the outer sleeve nut of the liquid filling tube. Tighten the outer sleeve nut on the liquid filling tube to start the liquid oxygen filling work; when oxygen needs to be output, connect the outer sleeve nut of the medical oxygen micro pressure reducer assembly to the liquid inlet (gas outlet) joint; the sealing ring is made of special glue to ensure that the bottle cap and the bottle body have a good sealing effect when they are closed; the spare vaporizer is when the vaporization capacity in the liquid oxygen bottle is not enough to provide the oxygen required by the patient, then unscrew the safety valve and install the spare vaporizer into the valve seat of the safety valve to accelerate the vaporization speed of the liquid oxygen in the bottle and ensure the oxygen supply demand.There are two methods for filling the oxygen supply bottle with liquid oxygen: Method 1, after the safety valve and the cryogenic working fluid valve body are respectively assembled into their respective valve seats on the bottle cap, the bottle cap is not assembled on the bottle body temporarily, and the liquid oxygen is dripped directly from the Dewar tank into the bottle body through the filling pipe. When the liquid oxygen surface reaches the scale shown on the bottle body, the valves of the Dewar tank and the filling pipe are immediately closed, and the sealing ring and the bottle cap are assembled on the bottle body. The bottle cap and the bottle body are tightened evenly with 6 sets of bolts as soon as possible, the valve core of the cryogenic working fluid valve body is closed to prevent leakage, and then the safety valve is adjusted to the safety scale. Method 2: Install the cryogenic working fluid valve body into the self-unloading valve seat on the bottle cap, and open the valve core on the cryogenic working fluid valve body, check whether the bottle cap and the bottle body are evenly tightened with the bolt assembly, do not install the safety valve first to discharge the gas in the bottle, put the outer nut of the filling pipe on the liquid inlet (gas outlet) joint on the side of the cryogenic working fluid valve body, and tighten it, then you can fill liquid oxygen from the Dewar tank into the bottle body. When the amount of gas overflowing from the valve seat mouth of the safety valve is small, it means that the filling of liquid oxygen is completed. You should first close the control valve on the Dewar tank and the valve on the filling pipe, then install the safety valve in the valve seat, adjust it to the safety scale, close the cryogenic working fluid valve body, loosen the outer nut, remove the filling pipe, and the filling work is completed. When it is necessary to supply oxygen to a patient who cannot take care of himself, first connect the medical oxygen micro-pressure reducer assembly to the oxygen inhalation tube on the nostrils (or mouth) of the person being rescued, turn off the oxygen supply switch, then connect the outer sheath nut to the liquid inlet (gas outlet) joint on the side of the cryogenic working fluid valve body, tighten the outer sheath nut, slowly unscrew the valve on the cryogenic working fluid valve body, slightly open the safety valve knob on the medical oxygen micro-pressure reducer assembly, and adjust the pressure and flow to meet the needs of first aid for the person receiving oxygen; if the person is conscious and has altitude sickness, he can slowly open the valve on the cryogenic working fluid valve body by himself, and directly inhale oxygen with his face facing the liquid inlet (gas outlet) joint on the side of the cryogenic working fluid valve body.

[0005] Comparison of the relevant technical parameters of this portable oxygen supply bottle for eliminating altitude sickness with standard medical oxygen cylinders and medical oxygen bags:

[0006] According to GB regulations, the dimensions of each 40 standard liter medical oxygen cylinder are: 22 cm in outer diameter, 150 cm in height, and 55 kg in weight. According to relevant data, the volume of liquid oxygen at the critical temperature (90K) is 0.8798 liters / kg (i.e. 1.13741 kg / liter), and when the temperature rises to 22°C (295K), the volume of 1 kg of oxygen is 766 standard liters. The pressure of a 40 liter standard medical oxygen cylinder is generally 12-13Mpa (calculated based on the middle value of 12.5Mpa, i.e. 125Kgf), and the amount of oxygen that can be provided is 40×125=5000 standard liters. A medical oxygen bag with a volume of 2 liters is filled with oxygen, because the oxygen bag is low-pressure, and can supply about 40 standard liters of oxygen.

[0007] The size of the portable oxygen supply bottle for eliminating altitude sickness is: outer diameter 11.2 cm (inner diameter 10 cm), outer height 20 cm (inner height 18 cm), the content of the bottle is 1.202 standard liters, calculated by the filling coefficient of 0.85, it can be filled with about 1.414 liters of liquid oxygen (about 1.367 kg of liquid oxygen), which is converted into the volume of oxygen 766 × 1.202 ÷ 0.8798 = 1046.524 standard liters, which is 0.21 times of the 40-liter standard medical oxygen cylinder; the weight of the portable oxygen supply bottle for eliminating altitude sickness is 1.53 kg, and the total weight (1.53 + 1.367) is 2.9 kg. Generally, a 40-liter standard medical oxygen cylinder can continuously deliver oxygen for about 60-84 hours (depending on the pressure and flow rate of oxygen supply required by the patient). The medical oxygen bag with a volume of 2 liters can only continuously provide oxygen for about 28.8-40.32 minutes because it is stored at low pressure. According to calculation, the oxygen supply bottle produced by the present invention can continuously deliver oxygen for about 13-18 hours (depending on the pressure and flow rate of the oxygen supply required by the patient), which can fully meet the first aid of altitude sickness. The portable oxygen supply bottle for eliminating altitude sickness has been tested under 22°C room temperature without the influence of shock and vibration, and the liquid oxygen in the bottle can be maintained for about 7-10 days (mainly affected by the pressure in the bottle set by the safety valve).

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This portable oxygen supply bottle for eliminating altitude sickness is sure to win the favor of patients with altitude sickness, medical staff and people who want safe production due to its excellent design and manufacturing, efficient ultra-low temperature effect and stable performance as well as its compact and light features. This portable oxygen supply bottle for eliminating altitude sickness has a novel design and reasonable structure, does not require batteries, is easy to fill with liquid oxygen and transport, is light and handy, easy to carry, simple to operate and very practical. It is sure to be a new type of oxygen supply equipment that is popular with everyone and is needed for first aid for altitude sickness. It is also suitable for oxygen supply needs when working in confined spaces or toxic places, and can also meet the oxygen inhalation needs of home health care, as well as first aid when working outdoors or traveling.
