TECHNICAL FIELD

[0001] The present application relates to the technical field of medical emergency hyperbaric oxygen supply equipment, in particular to a portable air film hyperbaric oxygen cabin for highland environment. BACKGROUND

[0002] In high-altitude areas of highlands, the oxygen content in the air is low. People who have long lived in low-altitude areas have difficulty in quickly adapting to the low-pressure and low-oxygen content atmospheric environment of high-altitude areas after entering the highlands, thereby causing a series of acute high-altitude reaction symptoms, and even endangering life and health in serious cases.

[0003] A large number of residents, soldiers and engineering personnel from low-altitude areas in China travel to high-altitude areas such as Tibet every year for tourism, garrison, engineering construction and maintenance, and emergency rescue. How to effectively deal with high-altitude reactions in high-altitude areas has become an important problem to be solved. The conventional measures for dealing with high-altitude reactions include oxygen inhalation, drug treatment, and descent of altitude. When high-altitude pulmonary edema, high-altitude cerebral edema and other critical conditions occur, due to the imbalance of the internal and external pressure of the human body, the effect of oxygen inhalation and drug treatment is limited.

A support rod base 34 is set at the bottom of the support rod 33.

[0030] The gas film hyperbaric oxygen cabin 1 is provided with a solar energy storage device 15, an inflation assembly, a ventilation device 19, and an oxygen generator device 20; the inflation assembly includes a gas pressure monitoring device 16, an automatic inflation device 17, and a control device 18. The automatic inflation device 17 inflates the gas film hyperbaric oxygen cabin 1 to provide rigidity to the film surface.

[0031] The gas film hyperbaric oxygen cabin 1 is provided with an inner film 11, which is in the shape of a gas bag, each gas bag is provided with an inflation nozzle for connecting or deflating a handheld inflation pump 35, and the inner film 11 is thermally bonded with the gas film hyperbaric oxygen cabin 1. The handheld inflation pump 35 inflates the gas bag quickly, and the gas in the gas bag has a heat insulation effect, which prevents the temperature in the cabin from changing significantly due to the drastic change of the outside temperature.

[0032] The bottom surface of the gas film hyperbaric oxygen cabin 1 is provided with a base film 7, and the outer bottom surface of the gas film hyperbaric oxygen cabin 1 is provided with a skirt film 12. The gas film hyperbaric oxygen cabin 1 is connected with a transition cabin 2; the gas film hyperbaric oxygen cabin 1, the inner film 11, the skirt film 12, the base film 7, and the transition cabin 2 form a sealed space as a whole, which prevents the change of the cabin pressure caused by gas leakage.

[0033] The outer surface of the gas film hyperbaric oxygen cabin 1 is covered with a flexible photovoltaic film 13, which supplies power to the oxygen generator device 20 to produce oxygen by electrolyzing water. The oxygen generator device is connected with a hydrogen pipe 29, an oxygen pipe 30, and an oxygen mask 31. The gas film hyperbaric oxygen cabin 1 is provided with an inflatable bed 22 inside; the gas film hyperbaric oxygen cabin 1 has a folding storage function.

[0034] The transition cabin 2 is provided with a first aluminum alloy sealing door 3 at the communication part with the outside, the first aluminum alloy sealing door 3 is covered with a photovoltaic panel, and the photovoltaic panel is provided with a photovoltaic control device 25.

[0035] When the gas film hyperbaric oxygen cabin is used in construction sites, military bases and other occasions, the carbon fiber framework is built to form a three-dimensional support rod to prevent external strong winds and heavy snow from causing excessive deformation of the gas film hyperbaric oxygen cabin 1. The gas film hyperbaric oxygen cabin 1 is reinforced by placing aluminum alloy pressure plates 21 on the skirt film 12 and piling up stones and sand on the spot to press the skirt film 12, and setting up a cable 14 connected to an embedded cone 9 inserted into the soil, to prevent excessive deformation of the gas film hyperbaric oxygen cabin 1 under strong winds and heavy snow.

The control device 18 uses a dynamic pressure adjustment algorithm to dynamically adjust the inflation amount according to the real-time air pressure in the cabin. When the oxygen generator device 20 is working, hydrogen is discharged outside the oxygen cabin, and oxygen is supplied to the personnel through the oxygen mask 31.

[0038] Therefore, the application adopts the above-mentioned portable air film pressurized oxygen cabin for highland environment, and the personnel suffering from high altitude reaction are placed in the fully-closed air film high pressure oxygen cabin, water is electrolyzed to generate oxygen by photovoltaic device power generation to supply oxygen for the personnel suffering from high altitude reaction; the air pressure inside the air film is adjusted to the air pressure in low altitude area by the air pressure monitoring device and the automatic inflation device, without reducing the altitude, to prevent and relieve the serious high reaction diseases such as brain edema and pulmonary edema caused by the imbalance of the pressure difference between the inside and outside of the body of the personnel suffering from high altitude reaction; the device is convenient to install, disassemble and carry, the transition cabin is used as a storage box, and after storage, it can be fixed on the roof and supply oxygen for the personnel in the vehicle.
