Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical auxiliary equipment, and particularly relates to a safe low-pressure oxygen supplement cabin suitable for multiple people and a control method thereof. BACKGROUND

[0002] Human cells can perceive 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 process of the human body. For example, providing a negative pressure environment at the wound of the human body can make the wound become a closed state, so that external bacteria cannot run into the wound to cause secondary infection. In addition, continuous wound negative pressure assisted healing can make wound exudate be discharged to the outside of the body in time and not accumulate in the wound, which is more conducive to wound tissue growth. At the same time, the negative pressure state can also make the wound tissue release various growth factors, thereby promoting wound healing, which can often make the wound that is difficult to heal before grow significantly faster and ultimately 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 function, thereby causing all-round harm to human health, and even possibly endangering life in severe cases.

[0004] In view of the series of effects of negative pressure environment on human health, a series of negative pressure health cabins with the above-mentioned health care functions have appeared on the market. For example, a kind of isolation space micro negative pressure oxygen-rich state regulation method, system and isolation rehabilitation cabin are proposed in Chinese invention patent No. CN202210806944.2. When the gas is extracted from the isolation space and the oxygen is input, the external air enters the isolation space in the closed state through the negative pressure air inlet balancing 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 maintained at a balance value, that is, the device maintains the air pressure value and the oxygen concentration value in a fixed range to achieve its function.

[0005] However, different users may have different sensitivities to air pressure and oxygen concentration, etc. For example, people who have lived in high-altitude areas for a long time have already adapted to the low-pressure and low-oxygen environment, and when they enter a conventional negative pressure cabin, they are less sensitive to the low-pressure and low-oxygen environment therein. For example, some users may have underlying diseases or be taking medication, 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 to be extremely uncomfortable, and if not intervened in time, they may even have a safety accident such as shock.

[0006] Therefore, it is particularly important to ensure the safety of users while ensuring the use effect, and therefore, a safe low-pressure oxygen supplement cabin is urgently needed. SUMMARY

[0007] The present application aims to provide a safe low-pressure oxygen supplement cabin suitable for multiple people and a control method thereof, so as to improve the safety of users during the use of the low-pressure oxygen supplement cabin.

[0012] As an improvement, further comprising: A user type identification module configured to identify the user type according to the user information, and adjust the current environmental parameter according to a third preset increment if the current user is a first user who has long lived in a low-pressure and low-oxygen area.

[0013] The application also provides a control method of a safe low-pressure oxygen supplement cabin suitable for multiple people, based on the safe low-pressure oxygen supplement cabin suitable for multiple people, comprising the following steps: S103 When the user enters the low-pressure oxygen supplement cabin, match the physiological data standard index, initial oxygen supply mode and initial environmental parameter index for the current user according to the age of multiple users, and control the low-pressure oxygen supplement cabin to work according to the initial environmental parameter index; wherein the oxygen is supplied by the nasal oxygen device in the initial oxygen supply mode; S104 Determine whether the user has feedback, if yes, go to S105, otherwise continue to execute S104; S105 Determine whether the real-time physiological data of the feedback user collected by the vital sign monitoring device matches the physiological data standard index; and mark the user who meets the requirement as a normal user, and mark the user who does not meet the requirement as an abnormal user; S106 Take soothing measures for the normal user, and the soothing measures include at least one of voice prompt and subtitle prompt; S108 When there is an abnormal user, and it is judged that the difference between the physiological data of at least one abnormal user and the physiological data standard index is less than the set threshold value, the environmental parameter is adjusted by a first preset increment, and step S109 is performed; when there is an abnormal user, and it is judged that the difference between the physiological data of at least one abnormal user and the physiological data standard index is greater than the set threshold value, the environmental parameter in the oxygen supplement cabin is gradually restored to the atmospheric environmental parameter. S109 The image collected by the image acquisition device is used to determine whether anyone in the abnormal user is in a motion state, and if at least one of the abnormal users is in a motion state, the initial oxygen supply mode is switched to a diffuse oxygen mode.

[0014] As an improvement, S106 further includes the following steps: S107 When the normal user is soothed for a first set time t1, the normal user is prompted to feedback again, and if the feedback result is comfortable, S104 is performed, and if the feedback result is uncomfortable, the oxygen supply concentration of the nasal oxygen equipment is increased and S105 is performed.

[0017] As an improvement, the following steps are further included: S112 The user type is identified according to the 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 parameter is adjusted by a third preset increment.

[0018] The principle and beneficial technical effects of the present application are: The present application comprehensively provides an energy-saving safe low-pressure oxygen supplement cabin, which can timely regulate according to different feelings and physiological reactions of different users with different sensitivity to low-pressure environment during use, so that the oxygen supplement cabin can adapt to different users while effectively improving the use safety of the oxygen supplement cabin.

[0019] On the one hand, different users have different sensitivities to low-pressure environment, when multiple people of the same age group are in the same cabin at the same time, if the cabin environment parameters are regulated by a unified standard without differentiation throughout the process, it is likely to cause extreme discomfort to the user with higher sensitivity, and even safety accidents. In the present scheme, each user can actively feedback through their respective feedback device, and the physiological indicators of the feedback user are monitored by the vital sign judgment module to identify the type of active feedback of the feedback user in combination with the physiological indicator parameters, different measures are taken for the oxygen supplement cabin according to different situations (for example, real feedback when physiological discomfort, and false feedback when psychological discomfort), for example, the user with the highest sensitivity is taken as the benchmark for regulation, so that the oxygen supplement cabin can ensure the safety of the user with the highest sensitivity, to more accurately adapt to the sensitivity of the current user to environmental changes, and ensure the safety of the user.

[0020] On the other hand, in the case of no feedback from the user, the vital sign judgment module actively intervenes, and the physiological data of the user is monitored in a timely manner, and the working mode of the oxygen supplement cabin is adjusted according to the physiological data, which can effectively avoid safety conditions in the case of physiological discomfort but no feedback from the user.

[0021] Generally, for users with different sensitivities, a large number of tests can be performed in advance on different users, or the environmental parameters are monitored in real time during use. However, although the individual sensitivity difference is large, it is not realistic to perform a large number of tests to find the environmental parameters that are comfortable for each user, and the physiological state of the user at different times also affects the sensitivity, so even if the aforementioned environmental parameters are obtained in advance, they are not suitable for any time. The way of monitoring the environmental parameters in real time to regulate the parameters in the cabin in real time not only requires a large amount of data processing by the system, but also requires a high system performance, which increases the energy consumption of the system, thereby increasing the cost. The environmental monitoring device and the vital sign monitoring device in the present application adopt an "intermittent" working mode, and data is collected in a targeted manner (i.e. there is a corresponding trigger mechanism), which not only effectively saves energy, but also greatly reduces the data processing amount of the system, reduces the requirement for system performance, thereby reducing the cost, and is more convenient for popularization.

[0022] Further, based on the more complex conditions in the multi-person oxygen supplement cabin, the present scheme divides the feedback users into normal and abnormal conditions, and introduces a motion state judgment, so that the oxygen supplement cabin can provide a more suitable oxygen supply mode for different states of the user.

The working principle of the diffuse oxygen device is to deliver oxygen into the isolation space of the low-pressure oxygen supplement cabin through a pipeline system, so that the oxygen is uniformly distributed in the isolation space; and the working principle of the nasal oxygen device is to deliver oxygen to an oxygen terminal, and then deliver the oxygen to the nasal cavity of a patient through a nasal catheter or a mask.

[0029] The application further comprises a master control device, and the master control device comprises: A data matching module is configured to match corresponding physiological data standard indicators, an initial oxygen supply mode and initial environmental parameter indicators for a current user according to the age of the current user when the user enters the low-pressure oxygen supplement cabin; the physiological data standard indicators comprise heart rate and blood pressure; the initial environmental parameter indicators comprise oxygen concentration, carbon dioxide concentration and air pressure; and oxygen is supplied through the nasal oxygen device in the initial oxygen supply mode. The physiological data standard indicators can also comprise body temperature, respiratory rate and the like; and the initial environmental parameters can also comprise temperature, humidity and the like.

[0030] A feedback recognition module is configured to judge whether a user has feedback and output a feedback signal; A judgment module is configured to judge whether real-time physiological data collected by the vital sign monitoring device matches the physiological data standard indicators when receiving the feedback signal of the user; and a user who meets the requirements is marked as a normal user, and a user who does not meet the requirements is marked as an abnormal user. a soothing module configured to take soothing measures for the normal user when there is at least one normal user, the soothing measures including turning on the nasal oxygen equipment to assist the user with supplementary oxygen supply, and at least one of voice prompting, subtitle prompting; a control module configured to control the low-pressure oxygen supplement cabin according to the initial environmental parameter index, and when it is judged that the difference between the physiological data of at least one abnormal user and the physiological data standard index is less than a set threshold, adjusting the environmental parameter by a first preset increment, and when there is an abnormal user and it is judged that the difference between the physiological data of at least one abnormal user and the physiological data standard index is greater than a set threshold, gradually restoring the environmental parameter in the oxygen supplement cabin to the atmospheric environmental parameter; That is, when the discomfort level of the abnormal user is relatively mild or general, the environmental parameter can be adjusted by appropriate adjustment, and when the discomfort level of one of the abnormal users is relatively serious, the environmental parameter in the cabin is restored to the atmospheric environmental parameter, which can effectively avoid safety accidents such as shock caused by continuing to be in a low-pressure and low-oxygen environment.

[0031] The judgment module is further configured to judge whether a person in the abnormal user is in a motion state through the image collected by the image collection device when there is an abnormal user. Correspondingly, the control module is further configured to switch the initial oxygen supply mode to a diffuse oxygen mode when at least one of the abnormal users is in a motion state.

[0032] In some embodiments, the image collection device can be a camera installed inside the low-pressure oxygen supplement cabin.

[0033] Wherein, "gradual recovery" means that the recovery is at a speed that the human body can adapt to, and does not cause adverse reactions due to too fast changes in environmental parameters, for example, adjusting the air pressure at a speed that the human body can adapt to, for example, 20 cmHg~25 cmHg air pressure change speed, wherein the speed can be determined in combination with the gas exchange flow rate of the low-pressure oxygen supplement cabin and the atmosphere.

[0034] In some embodiments, when the environmental parameter is gradually restored to the atmospheric environmental parameter, the environmental parameter can be adjusted by adjusting the air extraction rate, oxygen concentration, etc., and in other embodiments, the isolation space can be directly communicated with the outside, for example, opening the cabin door of the low-pressure oxygen supplement cabin for ventilation.

[0035] In some embodiments, it further includes a reminding module configured to prompt the user to feedback again after a first preset time t1 after soothing the user.

[0036] In some embodiments, the feedback device comprises at least two operation buttons, and the feedback signal comprises at least comfort and discomfort; when the user presses one of the buttons (e.g. the first button), it indicates that the user is currently comfortable; when the user presses the other button (e.g. the second button), it indicates that the user is uncomfortable; of course, in some specific embodiments, the second button can also comprise a plurality of sub-buttons, and the uncomfortable feedback signal can also be specifically divided into slight, general and severe, etc., and the plurality of sub-buttons represent different uncomfortable degrees, and the control module can take different control measures according to the feedback of the user.

[0037] In some embodiments, the control module is further configured to, when the user again feedbacks discomfort after being comforted for a first preset time length t1, adjust the first preset increment to a second preset increment, and the value of the second preset increment is greater than the value of the first preset increment.

[0038] In some embodiments, the method further comprises: a proactive monitoring module configured to, when the user has not feedback for a second preset time length t2, trigger the environment monitoring device to acquire the actual current environment parameter in the low-pressure oxygen supplement cabin, and start the vital sign monitoring device to monitor the real-time physiological data of the user.

[0039] In some embodiments, the method further comprises a user type identification module configured to identify the user type according to the user information, and if the current user is a first user who has been living in a low-pressure and low-oxygen area for a long time, adjust the current environment parameter according to a third preset increment. In this way, people with different living habits can be distinguished, and the best environment parameter for different users can be provided within a safe range, thereby improving the use effect of the low-pressure oxygen supplement cabin while ensuring the safety of the user.

[0040] In some embodiments, the control module is further configured to, when the user enters the low-pressure oxygen supplement cabin, trigger the environment monitoring device to perform a first monitoring; in the process of adjusting the environment parameter in the low-pressure oxygen supplement cabin according to the initial environment parameter, trigger the environment monitoring device to perform a second monitoring at a preset time; if the monitored current environment parameter reaches the initial environment parameter, control the devices of the low-pressure oxygen supplement cabin to maintain the current working state; if the monitored current environment parameter does not reach the initial environment parameter, adjust the power of the devices of the low-pressure oxygen supplement cabin; and when the user feedbacks (especially feedbacks discomfort), trigger the environment monitoring device to perform a third monitoring.

[0041] The scheme can effectively save energy and reduce the operation cost of the equipment under the premise of fully ensuring the safety of the user by adopting an intermittent working mode for the environmental monitoring equipment and the vital sign monitoring equipment and cooperating with a feedback device.

[0042] It should be noted that the first preset increment can be set differently for oxygen concentration, air pressure and carbon dioxide concentration, which are collectively referred to as "first preset increment" herein for the convenience of description; for example, when the current environmental parameters are adjusted according to the first preset increment, 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 according to the same rule as the first preset increment.

[0043] In some embodiments, the initial environmental parameters should meet the following basic parameter settings: the oxygen concentration is 21%-28%, the air pressure is-10kPa to-50kPa, and the carbon dioxide concentration is less than 0.5% (5000ppm); it should be noted that when the corresponding parameter range is selected according to the user's age, for example, the oxygen concentration is selected to be 24%-26%, for special users (for example, the first user in the plateau area), the current environmental parameters are not limited by the above range (oxygen concentration 24%-26%) when adjusting the current environmental parameters, but in principle, the adjustment should not exceed the control range of the basic parameters, so as to meet the individual needs of special users while ensuring user safety.

[0044] In some embodiments, an alarm module is further included for alarming when at least one of the environmental parameters (current environmental parameters) does not meet the basic parameters.

[0045] Embodiment two The application further provides a control method suitable for a safe low-pressure oxygen supplement cabin for multiple people, based on the safe low-pressure oxygen supplement cabin for multiple people of embodiment one, comprising the steps of: S103 when a user enters the low-pressure oxygen supplement cabin, matching physiological data standard indicators, an initial oxygen supply mode and initial environmental parameter indicators for the current user according to the age of multiple users, and controlling the low-pressure oxygen supplement cabin to work according to the initial environmental parameter indicators; wherein oxygen is supplied by the nasal oxygen equipment in the initial oxygen supply mode; S104 determining whether a user has feedback, if yes, entering S105, otherwise, continuing to execute S104; S105 determining whether the real-time physiological data of the feedback user collected by the vital sign monitoring equipment matches the physiological data standard indicators; and marking the user who meets the standard as a normal user and marking the user who does not meet the standard as an abnormal user; S106 taking a pacification measure on the normal user, the pacification measure comprising at least one of a voice prompt, a subtitle prompt; S108 when there is an abnormal user and it is judged that the difference between the physiological data of at least one abnormal user and the physiological data standard index is less than a set threshold, adjusting the environmental parameter by a first preset increment; when there is an abnormal user and it is judged that the difference between the physiological data of at least one abnormal user and the physiological data standard index is greater than a set threshold, gradually restoring the environmental parameter in the oxygen supplement cabin to an atmospheric environmental parameter.

[0046] wherein, "gradual restoration" refers to a speed that the human body can adapt to, and does not produce adverse reactions due to too fast changes in environmental parameters, for example, adjusting the air pressure at a speed of 20 cmHg~25 cmHg that the human body can adapt to, wherein the speed can be determined in combination with the gas exchange flow between the low-pressure oxygen supplement cabin and the atmosphere.

[0047] In some embodiments, when the environmental parameter is gradually restored to the atmospheric environmental parameter, the environmental parameter can be adjusted by adjusting the air extraction rate, oxygen supply concentration, etc., and in other embodiments, the isolation space can also be directly communicated with the outside, for example, opening the cabin door of the low-pressure oxygen supplement cabin for ventilation.

[0048] S109 judging whether at least one abnormal user is in a motion state through the image collected by the image acquisition device, and if at least one abnormal user is in a motion state, switching the initial oxygen supply mode to a diffuse oxygen mode (which can also be referred to as a second mode).

[0049] In some embodiments, S106 further comprises the following step: S107 after pacifying the normal user for a first set time t1, prompting the normal user to feedback again, if the feedback result is comfortable, executing S104, and if the feedback result is uncomfortable, increasing the oxygen supply concentration of the nasal oxygen equipment and executing S105.

[0050] In some embodiments, S104 further comprises the following step: S110 when the user has not fed back for a second set time t2, triggering the environmental monitoring device to obtain the actual current environmental parameter in the low-pressure oxygen supplement cabin, and starting the vital sign monitoring device to monitor the real-time physiological data of the user, and judging whether the real-time physiological data matches the physiological data standard index, if yes, maintaining the current environmental parameter, and otherwise adjusting the environmental parameter by a first preset increment.

[0051] In some embodiments, S107 further comprises the following step: S111If the normal user provides feedback again before the first set time t1 is reached after the normal user is appeased, go to S105.

[0052] In some embodiments, further comprising the step of: S112According to the user information, if the current user is the first user who has long-term lived in a low-pressure and low-oxygen area, adjust the current environmental parameter according to the third preset increment.

[0053] At present, the high-precision negative pressure cabin on the market usually uses monitoring equipment with high precision to monitor the environmental parameters in the cabin in real time, so that the production cost and use cost are greatly increased, and it is difficult to promote and use; and the present application actually provides a safe low-pressure oxygen supplement cabin with strong universality and low cost for multiple people.

[0054] Specifically, part of the equipment (such as environmental monitoring equipment and vital sign monitoring equipment) in the low-pressure oxygen supplement cabin in the present scheme adopts an intermittent working mode, which can effectively reduce the cost; on the one hand, the device supplies oxygen to the user through the nasal oxygen equipment in the initial mode, which can effectively deal with the situation that the number of people in the multi-person negative pressure cabin is large, the internal environmental influence factors are various and complex, and the environmental monitoring equipment and vital sign monitoring equipment cannot be adjusted in time when they are in standby state, thereby improving the safety of user use; on the other hand, in the case that the abnormal user moves, the oxygen supply mode is switched to the diffuse oxygen mode in time, which can effectively avoid the loosening of the nasal oxygen equipment or the pulling of the user when the user moves, further improve the user experience and ensure the safety of the user.

[0055] Further, the present application provides feedback equipment for user feedback, and adjusts the parameters in the low-pressure oxygen supplement cabin within a safe range according to the user feedback, which can effectively improve the user experience, that is, the environmental parameters in the isolation space are not "fixed", but "floating" within a safe range; and the physiological data of the user is monitored to determine the health status of the user when adjusting the parameters, and the parameters are adjusted according to the health status, which can effectively avoid the "misfeedback" of the user, and further, when the user does not provide feedback due to entering a sleep state or having a slow reaction, etc., the monitoring equipment is started to actively monitor, which can effectively avoid the user from continuing to maintain the current state without feedback and aggravating the discomfort, and even causing a safety accident such as shock.

[0056] In summary, the present application adjusts the internal parameters of the low-pressure oxygen supplement cabin in combination with the feedback mechanism, the health monitoring mechanism, the active adjustment mechanism, etc., and comprehensively provides a personalized safe low-pressure oxygen supplement cabin for multiple people, which ensures the use effect while fully ensuring the safety of the user.
