Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a safe low-pressure oxygen supplementation chamber and a control method thereof. Background Art

[0002] Human cells can sense and respond to external environmental stimuli such as low pressure, and play a key role in the metabolic process. Based on this, local low pressure plays an indispensable role in the growth and development of the human body. For example, providing a negative pressure environment at the wound of the human body can make the wound become closed, so that no external bacteria can enter the wound and cause secondary infection; coupled with continuous negative pressure to assist wound healing, the wound fluid can be discharged to the body in time and will not accumulate in the wound, which is more conducive to the growth of wound tissue; at the same time, the negative pressure state can also enable the wound tissue to release various growth factors, thereby promoting wound healing, which can often make wounds that were previously difficult to heal grow significantly faster and eventually heal.

[0003] However, while providing a low-pressure environment, the oxygen concentration in the air will decrease, and a low-oxygen environment can easily lead to a decline in human body functions, thereby causing all-round harm to human health, and in severe cases may even be life-threatening.

[0004] In view of the series of effects of negative pressure environment on human health, a series of negative pressure health care cabins with the above-mentioned health care functions have appeared on the market. For example, the Chinese invention patent with application number CN202210806944.2 proposes a method, system and isolation rehabilitation cabin for regulating the micro-negative pressure and oxygen-rich state in an isolation space. When gas is extracted into the isolation space and oxygen is input, external air enters the closed isolation space through the negative pressure air intake balance device, so that the isolation space is in a micro-negative pressure state; by setting the amount of extracted gas, the amount of oxygen input and the oxygen concentration, the oxygen concentration in the isolation space is at a balanced value. That is to say, the device achieves its function by maintaining the air pressure value and the oxygen concentration value within a fixed range.

[0005] However, different users may have different sensitivities to air pressure and oxygen concentration. For example, people who have lived in plateau areas for a long time have adapted to the low-pressure and low-oxygen environment. When they enter a conventional negative pressure cabin, they are less sensitive to the low-pressure and low-oxygen environment. For another example, some users may have underlying diseases or are taking medications, and they are more sensitive to external environmental stimuli. At this time, the low-pressure and low-oxygen environment in the negative pressure cabin may cause them extreme discomfort. If not intervened in time, even safety accidents such as shock may occur.

[0006] It can be seen that how to ensure the safety of users while ensuring the use effect is particularly important. Therefore, a safe low-pressure oxygen supplementation chamber is urgently needed. Summary of the invention

[0007] The object of the present invention is to provide a safe low-pressure oxygen supplementation chamber and a control method thereof, so as to improve the safety of users when using the low-pressure oxygen supplementation chamber.

[0008] In order to solve the above-mentioned technical problems, the present invention specifically adopts the following technical solutions: A safe low-pressure oxygen supplementation cabin comprises a cabin body, wherein an isolation space is arranged in the cabin body, wherein oxygen supply equipment, air extraction equipment, environmental monitoring equipment for monitoring environmental parameters in the cabin body, vital sign monitoring equipment for monitoring physiological data indicators of users, and feedback equipment for users to actively provide feedback are arranged in the isolation space, wherein the oxygen supply equipment comprises nasal oxygen equipment and diffuse oxygen equipment; It also includes a main control device, which includes: Data matching module: configured to match corresponding physiological data standard indicators and initial environmental parameter indicators for the current user according to the age group of the current user when the user enters the low-pressure oxygen supplementation chamber; the physiological data standard indicators include heart rate and blood pressure; the initial environmental parameter indicators include oxygen concentration, carbon dioxide concentration and air pressure; A physical sign judgment module: configured to judge whether the real-time physiological data collected by the physical sign monitoring device matches the physiological data standard indicator when receiving a feedback signal from the user; The control module is configured to control the operation of the low-pressure oxygen supplementation chamber according to the initial environmental parameter index; and when the real-time physiological data does not match the physiological data standard index, trigger the environmental monitoring device to obtain the actual current environmental parameters in the low-pressure oxygen supplementation chamber, and adjust the current environmental parameters according to a first preset increment, or control the environmental parameters in the low-pressure oxygen supplementation chamber to gradually return to the atmospheric environmental parameters; The soothing module is configured to take soothing measures for the user when the real-time physiological data matches the physiological data standard indicator; the soothing measures include turning on the nasal oxygen device to provide auxiliary oxygen to the user, and performing at least one of voice prompts and subtitle prompts.

[0009] As an improvement, it also includes: Reminder module: configured to prompt the user to provide feedback again after a first preset time t1 has been reached after the user has been comforted.

[0010] As an improvement, the control module is further configured to adjust the first preset increment to a second preset increment greater than the first preset increment when the user again reports discomfort after being soothed for a first preset time t1.

[0011] As an improvement, it also includes: Active monitoring module: configured to start the vital sign monitoring device to actively monitor the real-time physiological data of the user when the user has not provided any feedback for a second preset time period t2.

[0012] As an improvement, it also includes: User type identification module: configured to identify the user type according to the user information, and if the current user is the first user who lives in a low-pressure and low-oxygen area for a long time, adjust the current environmental parameters according to the third preset increment.

[0013] The present invention also provides a control method for a safe low-pressure oxygen supplementation chamber, based on the above oxygen supplementation chamber, comprising the steps of: S103: when the user enters the low-pressure oxygen supplementation chamber, matching physiological data standard indicators and initial environmental parameter indicators for the current user according to the age group of the current user, and controlling the low-pressure oxygen supplementation chamber to work according to the initial environmental parameter indicators; S104 determines whether the user provides feedback, if so, proceeds to S105, otherwise, S104 is repeatedly executed; S105 determines whether the real-time physiological data collected by the vital sign monitoring device matches the physiological data standard indicator. If so, enter S106. Otherwise, according to the user's feedback, trigger the environmental monitoring device to obtain the actual current environmental parameters in the low-pressure oxygen supplementation chamber, and adjust the current environmental parameters according to the first preset increment, or control the environmental parameters in the low-pressure oxygen supplementation chamber to gradually restore to the atmospheric environmental parameters; S106: taking soothing measures for the user, and turning on the nasal oxygen device to provide auxiliary oxygen to the user, wherein the soothing measures include at least one of voice prompts and subtitle prompts.

[0014] As an improvement, the steps are also included: S107: When the user is comforted for a first preset time t1, the user is prompted to give feedback again. If the user gives feedback that the user feels comfortable, S104 is executed. If the user gives feedback that the user feels uncomfortable, the oxygen concentration of the nasal oxygen device is increased and S105 is executed.

[0015] As an improvement, the step after S104 further includes: S108 When the user has not provided feedback for a second preset time period t2, the vital sign monitoring device is turned on to monitor the real-time physiological data of the user, and it is determined whether the real-time physiological data matches the physiological data standard indicators. If so, the current environmental parameters are maintained, otherwise the current environmental parameters are adjusted according to the first preset increment.

[0016] As an improvement, the following steps are further included before S107: S109 If, after the user is comforted, the user gives feedback again before the first preset time t1 is reached, the process proceeds to S105.

[0017] As an improvement, the steps are also included: S110 identifies the user type according to the user information, and if the current user is a first user who lives in a low-pressure and low-oxygen area for a long time, adjusts the current environmental parameters according to a third preset increment.

[0018] The principle and beneficial technical effects of the present invention are: The present application comprehensively provides an energy-saving, personalized, safe, low-pressure oxygen supplementation chamber, which can be adjusted in real time according to the different feelings and physiological reactions of different users during use, so that the oxygen supplementation chamber can adapt to different users while effectively improving the safety of use of the oxygen supplementation chamber.

[0019] On the one hand, different users have different sensitivities to low-pressure environments. For example, even under the same environmental parameters, some users may feel uncomfortable due to different sensitivities, while some users may not feel uncomfortable. Therefore, if an undifferentiated unified standard is used to regulate the environmental parameters in the cabin, it is very likely to cause extreme discomfort to users with higher sensitivity, and even safety accidents. In this solution, users can actively provide feedback through feedback devices, and at the same time, the physiological indicators of the feedback users are monitored through the physical sign judgment module to identify the user's active feedback type in combination with the physiological indicator parameters. Different measures are taken for users with different sensitivity levels through the oxygen supplementation chamber for different situations (such as real feedback when physiological discomfort occurs, and false feedback when psychological discomfort occurs), so that the oxygen supplementation chamber can be "personalized" for different users to more accurately adapt to the current user's sensitivity to environmental changes and ensure the user's safety.

[0020] On the other hand, when there is no feedback from the user, the vital sign judgment module actively intervenes, regularly monitors the user's physiological data, and adjusts the working mode of the oxygen supplementation chamber according to their physiological data, which can effectively prevent the user from encountering unsafe conditions when there is physiological discomfort but no feedback.

[0021] Usually, for users with different sensitivity levels, a large number of tests can be conducted on different users in advance, or the environmental parameters can be monitored in real time during use. However, although the individual sensitivity levels vary greatly, it is not realistic to conduct a large number of tests to find environmental parameters that are comfortable for each user, and the different physiological states of users at different times will also affect the sensitivity. Even if the aforementioned environmental parameters are obtained through advance testing, they are not suitable for any time. The method of real-time monitoring of environmental parameters to regulate various parameters in the cabin in real time not only requires a large amount of data to be processed by the system, but also has high requirements on system performance, and will also increase the energy consumption of the system, thereby causing higher costs. The environmental monitoring equipment and vital sign monitoring equipment in this application adopt an "intermittent" working mode, and carry out data collection in a targeted manner (that is, there is a corresponding trigger mechanism), which can not only effectively save energy, but also greatly reduce the data processing volume of the system, reduce the requirements for system performance, thereby reducing costs, and making it easier to promote.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two components.

[0027] Embodiment 1 The present invention provides a safe low-pressure oxygen supplementation cabin, comprising a cabin body, an isolation space is arranged in the cabin body, oxygen delivery equipment, air extraction equipment, environmental monitoring equipment for monitoring environmental parameters in the cabin body, vital sign monitoring equipment for monitoring physiological data indicators of users (such as JP2011 series multi-parameter monitors sold on the market), and feedback equipment for users to actively provide feedback, wherein the oxygen delivery equipment includes nasal oxygen equipment and diffuse oxygen equipment; Among them, the working principle of the diffused oxygen equipment is to transport oxygen to the isolated space of the low-pressure oxygen supplementation chamber through a pipeline system, so that the oxygen is evenly distributed in the isolated space; the working principle of the nasal oxygen equipment is to transport oxygen to the oxygen terminal, and then transport the oxygen to the patient's nasal cavity through a nasal catheter or mask.

[0028] It also includes a main control device, which includes: Data matching module: configured to match corresponding physiological data standard indicators and initial environmental parameter indicators for the current user according to the age group of the current user when the user enters the low-pressure oxygen supplementation chamber; the physiological data standard indicators include heart rate and blood pressure; the initial environmental parameter indicators include oxygen concentration, carbon dioxide concentration and air pressure; Among them, the physiological data standard indicators may also include body temperature, respiratory rate, etc.; the initial environmental parameters may also include temperature, humidity, etc.; Feedback identification module: configured to determine whether the user provides feedback; A physical sign judgment module: configured to judge whether the real-time physiological data collected by the physical sign monitoring device matches the physiological data standard indicator when receiving the feedback signal of the user; The control module is configured to control the operation of the low-pressure oxygen supplementation chamber according to the initial environmental parameter index; and when the real-time physiological data does not match the physiological data standard index, trigger the environmental monitoring device to obtain the actual current environmental parameters in the low-pressure oxygen supplementation chamber, and adjust the current environmental parameters according to a first preset increment, or control the environmental parameters in the low-pressure oxygen supplementation chamber to gradually return to the atmospheric environmental parameters; Here, "gradual recovery" means recovery at a speed that the human body can adapt to without causing adverse reactions due to rapid changes in environmental parameters. For example, the air pressure is adjusted at a speed of 20 cmHg to 25 cmHg that the human body can adapt to. The speed can be determined in combination with the gas exchange flow rate between the low-pressure oxygen supplementation chamber and the atmosphere.

[0029] In some embodiments, when the environmental parameters are gradually restored to the atmospheric environmental parameters, the environmental parameters can be adjusted by adjusting the exhaust rate, oxygen supply concentration, etc. In other embodiments, the isolation space can also be directly connected to the outside world, for example, by opening the door of the low-pressure oxygen supplementation chamber for ventilation.

[0030] The soothing module is configured to take soothing measures for the user when the real-time physiological data matches the physiological data standard indicator; the soothing measures include turning on the nasal oxygen device to provide auxiliary oxygen to the user, and performing at least one of voice prompts and subtitle prompts.

[0031] In some embodiments, a reminder module is also included: configured to prompt the user to provide feedback again after a first preset time t1 has been reached after the user has been comforted.

[0032] In some embodiments, the feedback device includes at least two operation buttons, and accordingly, the feedback signal includes at least comfort and discomfort; when the user presses one of the buttons (for example, the first button), it indicates that the user's current state is comfortable, and when the user presses another button (for example, the second button), it indicates that the user feels uncomfortable; of course, in some specific embodiments, the second button may also include multiple sub-buttons, and accordingly, the uncomfortable feedback signal may be specifically divided into mild, general and severe, etc., and the multiple sub-buttons represent different degrees of discomfort, and the control module may take different control measures according to the user's feedback.

[0033] In some embodiments, the control module is further configured to adjust the first preset increment to a second preset increment greater than the first preset increment when the user again reports discomfort after a first preset time t1 has elapsed since the user was soothed.

[0034] In some embodiments, an active monitoring module is also included: the module is configured to start the vital sign monitoring device to actively monitor the real-time physiological data of the user when the user has not provided feedback for a second preset time period t2.

[0035] In some embodiments, a user type identification module is further included: configured to identify the user type according to the user information, and if the current user is the first user who has lived in a low-pressure and low-oxygen area for a long time, the current environmental parameters are adjusted according to the third preset increment. In this way, people with different living habits can be distinguished, and the best environmental parameters can be provided for different users within a safe range, thereby improving the use effect of the low-pressure oxygen supplementation chamber while ensuring the safety of the user.

[0036] In some embodiments, the control module is also used to trigger the environmental monitoring device to perform a primary monitoring when the user enters the low-pressure oxygen supplementation chamber; to trigger the environmental monitoring device to perform a secondary monitoring at a preset time during the process of adjusting the environmental parameters in the low-pressure oxygen supplementation chamber according to the initial environmental parameters; if the current environmental parameters monitored reach the initial environmental parameters, the various devices of the low-pressure oxygen supplementation chamber are controlled to maintain the current working state; if the current environmental parameters monitored do not reach the initial environmental parameters, the power of the various devices of the low-pressure oxygen supplementation chamber is adjusted; and to trigger the environmental monitoring device to perform another monitoring when the user provides feedback (especially feedback of discomfort).

[0037] This solution adopts an "intermittent" working mode for environmental monitoring equipment and vital sign monitoring equipment, and cooperates with feedback devices to effectively save energy and reduce equipment operating costs while fully ensuring user safety.

[0038] It should be noted that the first preset increment can be set separately for oxygen concentration, air pressure and carbon dioxide concentration, and they are collectively referred to as the "first preset increment" here just for the convenience of description; for example, when adjusting the current environmental parameters according to the first preset increment, while the oxygen concentration is increased by 5%, the carbon dioxide concentration is reduced by 3% and the air pressure is increased by 10%; similarly, the second preset increment and the third preset increment are set using the same rules as the first preset increment.

[0039] In some embodiments, the initial environmental parameters should meet the following basic parameter settings: the oxygen concentration is 21% to 28%, the air pressure is -10kPa to -50kPa, and the carbon dioxide concentration is less than 0.5% (5000ppm). It should be noted that after selecting the corresponding parameter range according to the user's age group, for example, the oxygen concentration is selected as 24%-26%, for special users (such as the first user in a plateau area), the current environmental parameters are not restricted by the above range (oxygen concentration 24%-26%) when adjusting, but in principle the adjustment should not exceed the control range of the basic parameters, so as to meet the personalized needs of special users while ensuring user safety.

[0040] In some embodiments, an alarm module is further included, which is used to issue an alarm when at least one of the environmental parameters (current environmental parameters) does not meet the basic parameters.

[0041] Embodiment 2 The present invention also provides a control method for a safe low-pressure oxygen supplementation chamber, based on the low-pressure oxygen supplementation chamber in the first embodiment, comprising the steps of: S103: when the user enters the low-pressure oxygen supplementation chamber, matching physiological data standard indicators and initial environmental parameter indicators for the current user according to the age group of the current user, and controlling the low-pressure oxygen supplementation chamber to work according to the initial environmental parameter indicators; S104 determines whether the user provides feedback, if so, proceeds to S105, otherwise, S104 is repeatedly executed; S105 determines whether the real-time physiological data collected by the vital sign monitoring device matches the physiological data standard indicator. If so, enter S106. Otherwise, according to the user's feedback, trigger the environmental monitoring device to obtain the actual current environmental parameters in the low-pressure oxygen supplementation chamber, and adjust the current environmental parameters according to the first preset increment, or control the environmental parameters in the low-pressure oxygen supplementation chamber to gradually restore to the atmospheric environmental parameters; Here, "gradual recovery" means recovery at a speed that the human body can adapt to without causing adverse reactions due to rapid changes in environmental parameters. For example, the air pressure is adjusted at a speed of 20 cmHg to 25 cmHg that the human body can adapt to. The speed can be determined in combination with the gas exchange flow rate between the low-pressure oxygen supplementation chamber and the atmosphere.

[0042] In some embodiments, when the environmental parameters are gradually restored to the atmospheric environmental parameters, the environmental parameters can be adjusted by adjusting the exhaust rate, oxygen supply concentration, etc. In other embodiments, the isolation space can also be directly connected to the outside world, for example, by opening the door of the low-pressure oxygen supplementation chamber for ventilation.

[0043] S106: taking soothing measures for the user, and turning on the nasal oxygen device to provide auxiliary oxygen to the user, wherein the soothing measures include at least one of voice prompts and subtitle prompts.

[0044] In some embodiments, the step is further included: S107, when the user is comforted for a first preset time t1, the user is prompted to give feedback again. If the user gives feedback that the user is comfortable, S104 is executed. If the user gives feedback that the user is uncomfortable, the oxygen concentration of the nasal oxygen device is increased and S105 is executed.

[0045] In some embodiments, after S104, the following step is also included: S108: when the user has not provided feedback for a second preset time period t2, the vital sign monitoring device is turned on to monitor the real-time physiological data of the user, and it is determined whether the real-time physiological data matches the physiological data standard indicators. If so, the current environmental parameters are maintained, otherwise the current environmental parameters are adjusted according to the first preset increment.

[0046] In some embodiments, the step S109 is also included before S107: If the user gives feedback again after the user is comforted and before the first preset time t1 is reached, then enter S105.

[0047] In some embodiments, the step is further included: S110 performs user type identification based on user information, and if the current user is a first user who has lived in a low-pressure and low-oxygen area for a long time, the current environmental parameters are adjusted according to a third preset increment.

[0048] The present application can effectively improve the user experience by providing a feedback device for users to provide feedback, and adjusting the parameters in the low-pressure oxygen supplementation chamber within a safe range based on the user feedback. That is to say, the environmental parameters inside the isolation space are not "fixed", but can "float" within a safe range based on the user's situation; and, during the adjustment, by monitoring the user's physiological data to determine their health status, and adjusting the parameters based on their health status, it can effectively avoid the situation where users "give false feedback". Furthermore, when the user does not provide feedback due to reasons such as falling asleep or being slow to react, turning on the monitoring device for active monitoring can effectively avoid the user continuing to maintain the current state without feedback, thereby aggravating discomfort, or even causing safety accidents such as shock.

[0049] In summary, this application combines feedback mechanism, health monitoring mechanism, active control mechanism, etc. to regulate the internal parameters of the low-pressure oxygen supplementation chamber, and comprehensively provides a personalized and safe low-pressure oxygen supplementation chamber, which fully guarantees the safety of the user while ensuring the use effect.

[0050] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0051] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
