Description

Technical Field

[0001] This invention relates to the field of auxiliary training equipment technology, specifically to a hypoxia pre-acclimatization training device. Background Technology

[0002] Hypoxia and ischemia can trigger various bodily responses, including damaging reactions such as metabolic, functional, and morphological disorders caused by tissue hypoxia, and compensatory responses to improve tolerance to hypoxia. Damaging reactions refer to those caused by insufficient compensation due to severe or rapid hypoxia, such as pulmonary edema and cerebral edema. Compensatory responses refer to the protective compensatory responses triggered by mild or slow hypoxia caused by high-altitude living, polar expeditions, human diseases, and aging. Prolonged hypoxia can lead to excessive compensatory responses, which can induce changes in the function and structure of multiple systems, causing various diseases such as high-altitude heart disease. Hypoxia also contributes to decreased athletic performance at high altitudes. However, due to the body's adaptive mechanisms, people living at high altitudes have significantly greater resistance to hypoxia than those living at low altitudes, demonstrating that the body's physiological compensatory capacity can be improved through appropriate scientific training.

[0003] Existing hypoxia training methods commonly include hypoxia-hypobaric training equipment and portable hypoxia devices. Conventional hypoxia-hypobaric training equipment primarily creates a hypoxic environment to support training, such as the CN214344293U multi-functional hypoxia training device. This type of device, which creates a hypoxic environment, is costly and not suitable for widespread adoption. Conventional wearable hypoxia devices typically combine oxygen and nitrogen generators to regulate the oxygen concentration in the air during use, such as the CN110575596A intermittent hyper-hypoxia training system. These devices offer limited adjustability of the oxygen concentration in the training gas, making them inconvenient for training other activities. Furthermore, all hypoxia training devices lack the ability to provide rapid emergency treatment when the trainee experiences hypoxia symptoms, and cannot quickly switch between high and low oxygen levels, which can easily cause harm to the trainee.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] Example 1

[0043] A hypoxia preconditioning training device, such as Figure 1-5As shown, it includes: an electric air pump 1, which is connected to a molecular sieve 2 and an oxygen inhalation bottle 6; the other end of the oxygen inhalation bottle 6 is connected to a filling tube 7, wherein the oxygen inhalation bottle 6 contains reduced iron powder and activated carbon; the filling tube 7 is filled with cotton for filtering reduced iron powder and activated carbon or iron(III) oxide after reacting with oxygen; a high-oxygen storage tank 3, which is connected to the other end of the molecular sieve 2 through a first control solenoid valve, wherein the molecular sieve 2 contains artificially synthesized zeolite material; a low-oxygen storage tank 8, which is connected to the other end of the filling tube 7 through a second control solenoid valve; an air supply pipe 10, the air inlet of which is connected to the high-oxygen storage tank 3 and the low-oxygen storage tank 8 respectively, and an adjusting solenoid valve 4 is installed on the pipe connecting it to the high-oxygen storage tank 3; and a control pipe 14, the air inlet of which is connected to the air outlet of the air supply pipe 10 through a switch solenoid valve 5, and one side of which is connected to the high-oxygen storage tank 3 through a high-oxygen conduit 12. The device continuously supplies low oxygen at the output end of the low oxygen storage tank 8. The high oxygen storage tank 3 is connected to the low oxygen storage tank 8 through a pipe with a control valve. By controlling the opening of the solenoid valve, the oxygen content at the gas supply end can be further fine-tuned.

[0044] Furthermore, when trainees experience symptoms of hypoxia, they require immediate emergency treatment and rapid removal from the training environment. Therefore, if... Figure 2-5 As shown, it also includes: an adjusting plate 18, which passes through the control tube 14 perpendicular to the axis of the control tube 14, and has a rack 23 on its side; the two outer ends of the adjusting plate 18 are elastically connected to the outer wall of the control tube 14, and each set of elastic components includes: a mounting plate, which is fixedly installed at the end of the adjusting plate 18; a guide rod 21, which is fixedly installed on the mounting plate; and a limiting spring 17, which passes through the guide rod 21, and whose two ends are fixedly connected to the mounting plate and the outer wall of the control tube 14 respectively; wherein, a fixing rod 16 is fixedly installed at the bottom of the lower mounting plate, and a pull ring 15 is fixedly installed at the lower end of the fixing rod 16.

[0045] Also includes:

[0046] A fixed plate 25 is fixedly installed inside the control tube 14, near the air inlet end, and has a first sector-shaped notch on its surface; a sector gear 24 is rotatably mounted on the fixed plate 25 via a rotating shaft and meshes with a rack 23; a rotating plate 26 is fixedly installed on the rotating shaft, abutting against the fixed plate 25, and has a second sector-shaped notch that matches the first sector-shaped notch; a crank-slider structure has its crank rotating end fixedly connected to the rotating shaft, and its end fixedly equipped with an I-shaped piston 20; the I-shaped piston 20 is slidably installed at the connection between the high-oxygen conduit 12 and the control tube 14; a mask 11 is connected to the other end of the control tube 14; wherein, when the rack 23 drives the sector gear 24 to rotate, it drives the rotating plate 26 to rotate, closing the channel with the fixed plate 25, and pushes the I-shaped piston 20 to open the channel of the high-oxygen conduit 12 through the crank-slider structure. The crank-slider structure includes: a first connecting rod 27, one end of which is fixedly connected to the rotating shaft; and a second connecting rod 13, one end of which is rotatably connected to the other end of the first connecting rod 27, and the other end of which is rotatably connected to one end face of the I-shaped piston 20. To ensure transmission stability and avoid jamming, the rotating joints of the second connecting rod 13 with the first connecting rod 27 and the I-shaped piston 20 are all spherical joints.

[0047] Furthermore, it also includes a central control unit, such as a microcomputer, single-chip microcomputer, or programmable logic controller; an oxygen concentration monitor is installed on the pipeline between the control pipe 14 and the air supply pipe 10; the central control unit is electrically connected to the first control solenoid valve, the second control solenoid valve, the regulating solenoid valve 4, the switching solenoid valve 5, and the oxygen concentration monitor, and adjusts the opening degree of each solenoid valve according to the oxygen concentration value obtained by the oxygen concentration monitor. In addition, the outlet end of the air supply pipe 10 and one end of the oxygen inhalation bottle 6 are directly connected to a circulation pump 9 through a flexible hose. The circulation pump 9 obtains low-oxygen air for circulation, further reducing the oxygen content of the gas inside the low-oxygen storage tank 8 and increasing the low-oxygen control range.

[0048] To ensure the overall structure's airtightness, such as Figure 3 As shown, a sealing groove 22 is fixedly provided on the side of the inner wall of the control tube 14, and the sealing groove 22 is provided with a slot for accommodating the rack facing the inside of the tube; a sealing plate is provided on the groove wall of the sealing groove 22.

[0049] In addition, a touch panel flow meter is installed on the hose connecting the oxygen mask and the gas supply pipe 10; the touch panel flow meter is electrically connected to the central control unit to control the gas delivery volume.

[0050] In this embodiment:

[0051] It consists of an electric air pump 1, a two-way valve, a molecular sieve 2 (for adsorbing non-oxygen gases), and an oxygen inhalation bottle 6 (containing reduced iron powder and activated carbon, with filters at the inlet and outlet). The input end of the air compressor is used to draw in ambient air and is connected to the inlet end of the two-way valve. The two output ends of the two-way valve are connected to the molecular sieve 2 and the oxygen inhalation bottle 6, respectively. The output end of the molecular sieve 2 is connected to the input end of the high-oxygen storage tank 3, and the output end of the oxygen inhalation bottle 6 is connected to the input end of the low-oxygen storage tank 8.

[0052] In use, the output of the low-oxygen storage tank 8 continuously supplies low oxygen. The high-oxygen storage tank 3 is connected to the low-oxygen storage tank 8 via a pipe equipped with a control valve. By controlling the opening of the solenoid valve, the oxygen content at the supply end can be further fine-tuned. Specifically:

[0053] S1: Determine and set the required oxygen concentration for hypoxia training, and monitor the oxygen content using an oxygen concentration monitor while the trainee wears a mask.

[0054] S2: The electric air pump 1 is turned on by the central control unit, and the first control solenoid valve and the second control solenoid valve are also turned on.

[0055] S3: The pressurized air enters the molecular sieve 2 and oxygen absorption bottle 6 through the first double-way valve. The molecular sieve 2 is used for water removal and nitrogen removal, and the oxygen absorption bottle 6 is used for deoxygenation through the reduced iron powder and activated carbon inside. The air is then compressed and collected through the high oxygen storage tank 3 and the low oxygen storage tank 8.

[0056] S4: The opening of the regulating solenoid valve 4 is controlled by the central control unit to control the output of high-pressure oxygen from the high-oxygen storage tank 3 into the air supply pipe 10 to mix with the low-oxygen air continuously output from the low-oxygen storage tank 8. The oxygen content measured by the oxygen concentration monitor is obtained in real time, and the opening of the regulating solenoid valve 4 is adjusted in feedback until the oxygen concentration of the air output from the air supply pipe 10 meets the oxygen concentration requirements for training.

[0057] The low-oxygen air is obtained through circulation pump 9, which further reduces the oxygen content of the gas inside the low-oxygen storage tank 8 and increases the low-oxygen control range.

[0058] Furthermore, this embodiment also provides an emergency oxygen supply structure. Specifically, as shown below... Figure 3-4 As shown.

[0059] In the initial state, the first and second sector-shaped notches between the fixed plate 25 and the rotating plate 26 coincide, supplying low-oxygen gas. When an emergency switch to high-oxygen mode is required, pulling the pull ring 15 causes the internal rack to move downward, simultaneously driving the sector gear 24 to rotate.

[0060] At this time, the rotation of sector gear 24 drives the rotation shaft to rotate, which in turn drives the rotation plate 26 to rotate, closing the channel between the rotation plate 26 and the fixed plate 25. The rotation of the rotation shaft drives the crank-slider structure, causing the I-shaped piston 20 to slide at the channel opening of the high-oxygen pipeline 12, realizing the opening and closing of the high-oxygen pipeline 12, and ultimately achieving emergency oxygen supply.

[0061] When the trainee releases their grip, the limiting spring 17 returns to its original position, the hypoxia channel opens and closes the hyperxia channel, and the trainee re-enters the hypoxia training mode.

[0062] This device dilutes the oxygen content by introducing outside air and mixing high-oxygen and low-oxygen gases to deliver the required oxygen concentration for training. From an application perspective, this device solves the problem of traditional oxygen generators (or storage devices) being generally large and heavy, hindering various training activities. By introducing outside air into the device through a self-designed mechanism to dilute the oxygen content for delivery, it meets the needs of various routine low-oxygen training programs. Furthermore, the device includes an emergency oxygen supply system. When a trainee experiences symptoms of low oxygen, requiring rapid intervention and removal from the training environment, the device can close the low-oxygen channel and switch to the high-oxygen channel via the drive adjustment plate 18. This emergency switching is simple and allows for timely delivery of high oxygen in emergencies while ensuring the smooth operation of low-oxygen training, preventing discomfort and confusion caused by prolonged low oxygen levels.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
