Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oxygen cabin equipment, in particular to a single-person oxygen cabin pulse type oxygen inhalation adjusting system and an adjusting method thereof. BACKGROUND

[0002] The oxygen cabin is a special medical equipment for high-pressure oxygen therapy, and its principle is to place the user in an environment with higher than normal atmospheric pressure and rich oxygen. Under the action of high pressure, oxygen is input into the respiratory and microcirculation system to reach all organs of the human body, thereby improving the arterial blood oxygen partial pressure and oxygen saturation level to promote human metabolism.

[0003] The current common high-pressure oxygen cabin oxygen inhalation mode is divided into closed oxygen inhalation and open oxygen inhalation. Among them, the closed oxygen inhalation refers to using a special oxygen inhalation mask, the oxygen inhalation mask is connected with an air inlet pipe and an air outlet pipe, the air inlet pipe is connected with a large-flow oxygen source outside the cabin, and the air outlet pipe is directly connected to the air outside the cabin. The large-flow oxygen enters from the air inlet pipe and is discharged from the air outlet pipe, and the oxygen is always in internal circulation. After the user wears the oxygen inhalation mask, an independent space is formed inside the oxygen inhalation mask, which is not affected by the pressure in the oxygen cabin. Since the independent space is always in oxygen internal circulation, the user can inhale fresh oxygen when inhaling, and the waste gas such as carbon dioxide is discharged outside the cabin along with the oxygen circulation. This scheme can ensure that the user always inhales high-concentration oxygen, but has a disadvantage that a large enough oxygen flow is required to ensure that the oxygen circulation with sufficient flow can supply the user to inhale oxygen. The current common household oxygen generator cannot meet this flow requirement, and often needs an industrial oxygen generator or centralized oxygen supply in a hospital or other place to meet the requirement, which is not suitable for household single-person use. Another oxygen inhalation mode is open oxygen inhalation, that is, a nasal oxygen tube or earphone type oxygen inhalation tube is used to place the oxygen outlet in the nasal cavity or around the nasal cavity, and the oxygen provided is inhaled into the user's body together with the surrounding air. Although this oxygen inhalation mode does not require large-flow oxygen, the inhaled oxygen is mixed with air, and the oxygen concentration cannot be guaranteed, which will affect the treatment effect. SUMMARY

[0004] The present application provides a single-person oxygen cabin pulse type oxygen inhalation adjusting system and an adjusting method thereof to solve the technical problem that the household oxygen cabin in the prior art cannot meet the closed oxygen inhalation.

[0005] To solve the above problems, the single-person oxygen cabin pulse type oxygen inhalation adjusting system provided by the present application adopts the following technical scheme: a cabin body is provided, the cabin body is installed with a cabin door and an automatic pressure relief valve for pressure relief to maintain the stability of the air pressure in the cabin body;

[0006] An oxygen buffer tank is also included for temporarily storing oxygen, which is installed outside the cabin and has one end connected to the cabin and the other end connected to the external high-pressure oxygen generator through a pipeline.

[0007] An oxygen outlet electromagnetic valve and an oxygen tank exhaust valve are sequentially installed on the pipeline between the oxygen buffer tank and the external high-pressure oxygen generator, the oxygen outlet electromagnetic valve is used for discharging oxygen, and the oxygen tank exhaust valve is used for exhausting air in the oxygen buffer tank.

[0008] An oxygen inhalation mask is arranged in the cabin, which is used for oxygen inhalation by the user, and has an air inlet pipe and an air outlet pipe, both of which extend to the outside of the cabin.

[0009] An air electromagnetic valve is also connected to the pipeline between the external air compressor and the oxygen inhalation mask, and the other end of the oxygen outlet electromagnetic valve is connected to the pipeline between the air electromagnetic valve and the oxygen inhalation mask through a pipeline.

[0010] A micro pressure difference sensor is connected to the pipeline between the external air compressor and the oxygen inhalation mask through a pipeline, which is used for detecting the change of air pressure in the oxygen inhalation mask.

[0011] As a further improvement, the sealing slide is fixedly connected with a sealing ring.

[0012] As a further improvement, one end of the oxygen buffer tank is provided with an air pipe interface for connecting with the external high-pressure oxygen generator, and the other end of the oxygen buffer tank is fixedly connected with a curved connecting pipe.

[0013] By adopting the above technical scheme, the currently commonly used household high-pressure oxygen generator can be used for closed oxygen inhalation treatment at home.

[0014] The sealing slide in the oxygen buffer tank divides the space in the tank into two independent cavities, and the sealing slide can slide axially along the oxygen buffer tank to change the volume of the two cavities.

[0015] In specific use, the air compressor pressurizes the cabin, the sealing slide moves to the side of the air pipe interface, and at this time the oxygen tank exhaust valve is opened to exhaust; after the air near the side of the air pipe interface is exhausted, the high-pressure oxygen generator is started, the oxygen tank exhaust valve is closed, the high-pressure oxygen generator adds oxygen to the oxygen buffer tank, and the sealing slide slides to the side near the curved connecting pipe until the oxygen buffer tank is filled with oxygen.

[0016] When the user inhales, the micro pressure difference sensor detects that the air pressure in the oxygen inhalation mask decreases, the air electromagnetic valve is closed and the oxygen electromagnetic valve is opened, at this time the oxygen in the high pressure oxygen generator and the oxygen in the oxygen buffer tank enter the oxygen inhalation mask at the same time, ensuring the supply of large flow oxygen required for the oxygen inhalation mask.

[0017] Conversely, when the user exhales, the micro pressure difference sensor detects that the air pressure in the oxygen inhalation mask increases, the air electromagnetic valve is opened and the oxygen electromagnetic valve is closed, at this time the air enters from the air inlet pipe of the oxygen inhalation mask and is discharged from the exhaust pipe, carrying out the exhaust gas exhaled by the user.

[0018] The subsequent cycle switches the above two states to ensure that the user inhales high-concentration oxygen in a pulse mode.

[0019] The application also discloses a single-person oxygen cabin pulse oxygen inhalation adjusting method, which adopts the single-person oxygen cabin pulse oxygen inhalation adjusting system and comprises the following steps.

[0020] S1, pressure rise, the user enters the cabin body, wears the oxygen inhalation mask, and closes the cabin door; at the same time, the air compressor is started, the air electromagnetic valve is opened, one air path of the air compressor is connected with the air inlet pipe of the oxygen inhalation mask, air path circulation is provided, and normal breathing of the user is ensured; another air path of the air compressor is connected with the cabin body to increase the pressure of the cabin body;

[0021] At the same time, the oxygen tank exhaust valve is also opened, the oxygen tank exhaust valve is connected with air, and as the pressure in the cabin body increases, the sealing sliding block in the oxygen buffer tank moves towards the air pipe interface end, and after the air near the air pipe interface side of the sealing sliding block in the oxygen buffer tank is completely discharged, the oxygen tank exhaust valve is closed;

[0022] S2, oxygen is added to the oxygen buffer tank, the high pressure oxygen generator is started, at this time oxygen enters the oxygen buffer tank, and as the pressure provided by the high pressure oxygen generator is higher than the treatment pressure of the cabin body, the sealing sliding block in the oxygen buffer tank moves towards the curved connecting pipe end, oxygen gradually fills the oxygen buffer tank, and the pressure in the oxygen buffer tank is increased to balance with the outlet gas pressure of the high pressure oxygen generator, during the process, the cabin body is continuously pressurized and the user continuously inhales air to maintain breathing;

[0023] S3, pulse oxygen inhalation, when the pressure in the cabin body rises to the treatment pressure, at this time, the micro pressure difference sensor connected through the oxygen inhalation mask can detect the pressure change in the oxygen inhalation mask;

[0024] When the pressure in the oxygen inhalation mask begins to drop, it indicates that the user is starting to inhale, at this time, the air electromagnetic valve is closed and the oxygen electromagnetic valve is opened, the oxygen from the high-pressure oxygen generator and the oxygen in the oxygen buffer tank are simultaneously introduced into the oxygen inhalation mask, the flow of oxygen from the high-pressure oxygen generator is stable due to the flow meter control, and when the oxygen in the oxygen buffer tank decreases, the pressure in the oxygen buffer tank decreases, but is always higher than or equal to the cabin pressure, which can ensure continuous oxygen outflow, and the oxygen flow at this time is much larger than the oxygen flow of a single oxygen generator, which can ensure the supply of large-flow oxygen required for oxygen inhalation of the oxygen inhalation mask;

[0025] When the pressure in the oxygen inhalation mask begins to rise, it indicates that the user is starting to exhale, at this time, the air electromagnetic valve is opened and the oxygen electromagnetic valve is closed, at this time, air enters the oxygen inhalation mask from the air inlet pipe and is discharged from the exhaust pipe, carrying out the waste gas exhaled by the user, at the same time, the high-pressure oxygen generator fills the oxygen buffer tank with oxygen again to ensure the continuous operation of the oxygen buffer tank.

[0026] With the treatment, the subsequent cycle switches between the above two states to ensure that the user inhales high-concentration oxygen in a pulse manner.

[0027] The beneficial effects of the above technical solutions of the present application are as follows:

[0028] 1. The present application utilizes the characteristics of respiration, when the user exhales, air is used to discharge the waste gas exhaled by the user, at the same time, the oxygen from the high-pressure oxygen generator is temporarily stored in the oxygen buffer tank, which can reduce the waste of this part of oxygen and effectively utilize this part of oxygen; when the user inhales, the high-pressure oxygen generator and the oxygen buffer tank supply gas to the oxygen inhalation mask at the same time; thereby realizing that the user in the single-person cabin in the home scenario can inhale high-concentration oxygen by the closed pulse oxygen inhalation mode under the premise of using a household high-pressure oxygen generator, thereby achieving better treatment effect.

[0029] 2. By the closed oxygen inhalation mode, the accumulation of carbon dioxide concentration in the cabin can be greatly reduced to ensure the health and safety of the user.

[0030] 3. The present application realizes that the user inhales high-concentration oxygen without the need for an industrial oxygen generator or centralized oxygen supply in a hospital or the like, at the same time, the structure of the present technical solution is not complex, and the closed oxygen inhalation treatment in the home scenario can be realized without increasing too much cost, which is more practical and more conducive to popularization and use.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be known by those skilled in the art that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0042] Compared with open type oxygen inhalation treatment, closed type oxygen inhalation treatment can ensure sufficient oxygen and has relatively better treatment effect. In the prior art, closed type oxygen inhalation treatment needs industrial oxygen generator or centralized oxygen supply in hospitals and other places to meet the demand. The commonly used household oxygen generator is difficult to meet the flow demand and is not suitable for single-person household use.

[0043] In view of the above problems, the single-person oxygen cabin pulse type oxygen inhalation regulation system is designed, which realizes closed type oxygen inhalation treatment in a household scene without additional oxygen tank and other oxygen supply equipment.

[0044] The basic principle is that, by using the characteristics of the closed oxygen cabin and breathing, it is found that the existing closed oxygen cabin system is continuous oxygen supply, and the user is supplied with oxygen when inhaling; and the main role of the oxygen provided by the oxygen cabin system when the user exhales is to carry out the exhaust gas.

[0045] The oxygen buffer tank 200 for temporarily storing oxygen and the micro pressure difference sensor 600 for detecting the pressure change of the oxygen inhalation mask 700 are arranged, when the user exhales, the pressure in the oxygen inhalation mask 700 increases, the oxygen inhalation mask 700 is switched to the air compressor line, and the exhaust gas is discharged through air; at the same time in the process of exhaling, the high-pressure oxygen generator temporarily stores the oxygen generated to the oxygen buffer tank 200. When the user inhales, the pressure in the oxygen inhalation mask 700 decreases, the oxygen inhalation mask 700 is switched to the oxygen supply line, and the high-pressure oxygen generator and the oxygen buffer tank 200 simultaneously deliver oxygen to the oxygen inhalation mask 700, at this time, the oxygen flow is much larger than the oxygen flow of a single high-pressure oxygen generator, which ensures that the user inhales high-concentration oxygen.

[0051] The sealing sliding block 210 is used to divide the space in the tank into two cavities independent of each other, and the sealing sliding block 210 can slide along the oxygen buffer tank in the axial direction, so as to change the volume of the two cavities.

[0052] The oxygen buffer tank 200 and the pipeline between the external high-pressure oxygen generator are sequentially provided with an oxygen outlet electromagnetic valve 300 and an oxygen tank exhaust valve 400, the oxygen outlet electromagnetic valve 300 is used for discharging oxygen, and the oxygen tank exhaust valve 400 is used for exhausting air in the oxygen buffer tank 200, in the embodiment, the oxygen outlet electromagnetic valve 300 and the oxygen tank exhaust valve 400 are connected to the pipeline between the oxygen buffer tank 200 and the external high-pressure oxygen generator through a three-way pipe;

[0053] The oxygen inhalation mask 700 is arranged in the cabin body 100, and the oxygen inhalation mask 700 is used for the user to inhale oxygen, the oxygen inhalation mask 700 has an air inlet pipe and an air outlet pipe, and the air inlet pipe and the air outlet pipe extend to the outside of the cabin body 100; the external air compressor divides two air paths through a three-way pipe, one of the air paths of the external air compressor is connected with the air inlet pipe of the oxygen inhalation mask 700, and the other air path of the external air compressor is connected with the cabin body 100;

[0054] The pipeline between the external air compressor and the oxygen inhalation mask 700 is further connected with an air electromagnetic valve 500, and the other end of the oxygen outlet electromagnetic valve 300 is connected to the pipeline between the air electromagnetic valve 500 and the oxygen inhalation mask 700 through a pipeline;

[0055] The micro pressure difference sensor 600 is connected with the oxygen inhalation mask 700 through a pipeline, and the micro pressure difference sensor 600 is used for detecting the change of air pressure in the oxygen inhalation mask 700.

[0056] The embodiment further discloses a single-person oxygen cabin pulse type oxygen inhalation adjusting method, and the single-person oxygen cabin pulse type oxygen inhalation adjusting system is used, and the method comprises the following steps:

[0057] S1, pressurization, as shown in Figure 2 and Figure 3 The user enters the inside of the cabin body 100, wears the oxygen inhalation mask 700, and closes the cabin door 120; at the same time, the air compressor is started, the air electromagnetic valve 500 is opened, one air path of the air compressor is connected with the air inlet pipe of the oxygen inhalation mask 700, the air path is circulated, and normal breathing of the user is ensured; the other air path of the air compressor is filled into the cabin body 100 to increase the pressure of the cabin body 100;

[0058] At this time, the oxygen outlet electromagnetic valve 300 is in a closed state;

[0059] The oxygen tank exhaust valve 400 is also opened at the same time, and the oxygen tank exhaust valve 400 is connected to the air. As the pressure in the cabin 100 rises, the sealing sliding block 210 in the oxygen buffer tank 200 moves to the air pipe interface end. Until the air near the air pipe interface side of the sealing sliding block 210 in the oxygen buffer tank 200 is completely exhausted, the oxygen tank exhaust valve 400 is closed.

[0060] S2, oxygen is added to the oxygen buffer tank 200, as shown in Figure 4 and Figure 5 The high-pressure oxygen generator is started, at which time the oxygen enters the oxygen buffer tank 200. Since the pressure provided by the high-pressure oxygen generator is higher than the treatment pressure of the cabin 100, the sealing sliding block 210 in the oxygen buffer tank 200 moves to the curved connecting pipe end. Oxygen gradually fills the oxygen buffer tank 200, and the pressure in the oxygen buffer tank 200 is increased to balance with the outlet gas pressure of the high-pressure oxygen generator. During this process, the pressure in the cabin 100 continues to increase, and the user continues to inhale air to maintain breathing;

[0061] S3, pulse oxygen inhalation, as shown in Figure 6 and Figure 7 When the pressure in the cabin 100 rises to the treatment pressure, the micro-pressure difference sensor 600 connected by the oxygen inhalation mask 700 can detect the pressure change in the oxygen inhalation mask 700 at this time;

[0062] When the pressure in the oxygen inhalation mask 700 begins to drop, it indicates that the user is starting to inhale. At this time, the air electromagnetic valve 500 is closed and the oxygen outlet electromagnetic valve 300 is opened. The high-pressure oxygen generator and the oxygen in the oxygen buffer tank 200 simultaneously enter the oxygen inhalation mask 700. The flow of the high-pressure oxygen generator is stable due to the flow meter control. When the oxygen in the oxygen buffer tank 200 decreases, the pressure in the oxygen buffer tank 200 decreases, but always remains higher than or equal to the cabin pressure, which can ensure continuous oxygen outflow. The oxygen flow at this time is much larger than the oxygen flow of a single oxygen generator, which can ensure the large-flow oxygen supply required by the oxygen inhalation mask 700. At the same time, as the oxygen in the oxygen buffer tank 200 is exhausted, the sealing sliding block 210 moves to the air pipe interface side;

[0063] When the pressure in the oxygen inhalation mask 700 begins to rise, it indicates that the user is starting to exhale. At this time, the air electromagnetic valve 500 is opened and the oxygen outlet electromagnetic valve 300 is closed. At this time, air enters the inhalation mask 700 from the air inlet pipe and is discharged from the exhaust pipe, carrying away the waste gas exhaled by the user. At the same time, the high-pressure oxygen generator again charges the oxygen buffer tank 200 with oxygen to ensure the continuous operation of the oxygen buffer tank 200;

[0064] As the treatment progresses, the subsequent cycle switches between the above two states to ensure that the user inhales high-concentration oxygen in a pulse manner.

[0065] While the specification has shown and described various embodiments of the present application, it is to be understood that these embodiments are merely illustrative of the many possible specific embodiments which embody the principles of the present application. Numerous and varied embodiments have been contemplated as being within the scope of the present application. It will be apparent to those skilled in the art that substantial modifications, changes and adaptations can be made in the application without departing from the spirit or scope of the application. It is understood that each of the features described herein can be replaced by alternative features serving the same, equivalent or similar purpose, resort being made to the disclosure of this application which is incorporated herein by reference.
