[0056] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0057] The embodiment of the present invention provides a control method for an oxygen production system, which is used to automatically control the oxygen production pressure and oxygen output rate of the oxygen production system in a timely manner according to the changes in the physiological parameters of the user, so that the physiological parameters of the user change to the expected normal state. The process is as follows: Figure 1 As shown, the following steps are included:

[0058] Step 1: Obtain the threshold interval of normal pulse rate and the threshold of normal blood oxygen saturation;

[0059] Step 2: receiving a pulse rate monitoring value and a blood oxygen saturation monitoring value of a user of the oxygen generation system;

[0060] Step 3: Control the oxygen output of the oxygen generation system according to the threshold range, the threshold, and the received pulse rate monitoring value and blood oxygen saturation monitoring value.

[0061] It should be noted that the pulse rate and blood oxygen saturation monitoring values ​​are the pulse rate and blood oxygen saturation values ​​of the oxygen production system user collected by the monitoring equipment, for example, the pulse rate of the user is monitored by a pulse rate monitor or a pulse diagnosis instrument, the blood oxygen saturation of the user is monitored by a blood oximeter, or the pulse rate and blood oxygen saturation of the user are monitored by a pulse oximeter. The oxygen output of the oxygen production system can be the oxygen production pressure and / or the oxygen output rate.

[0062] Compared with the prior art, the technical advantages of this embodiment are:

[0063] 1. It can automatically adjust the performance parameters of the oxygen production system in a timely manner, which is convenient for users with limited expression or mobility, and does not require real-time care from nursing staff;

[0064] 2. Automatically adjust according to monitoring data, and adjust system parameters in time when the user's physical condition changes. When it is detected that the user's physical condition does not meet the requirements, adjust the system parameters in time to meet the needs of the user at the current moment. When it is detected that the user's physical condition is normal, maintain the parameters unchanged to reduce system power consumption.

[0065] With reference to the normal threshold values ​​of pulse rate and blood oxygen saturation parameters set according to the user's basic physical condition, by monitoring the changes in the user's pulse rate and blood oxygen saturation parameters, the oxygen production pressure and oxygen output rate of the oxygen production system are automatically adjusted in a timely manner to meet the needs of the user at the current moment.

[0066] In some embodiments, in order to accurately control the oxygen output of the oxygen production system, the control logic is set as follows:

[0067] When the blood oxygen saturation monitoring value is less than the threshold value, the oxygen production pressure of the oxygen production system is controlled to increase, and the oxygen output rate of the oxygen production system is controlled to increase;

[0068] When the blood oxygen saturation monitoring value is greater than or equal to the threshold, it is determined whether to adjust the oxygen production pressure and oxygen output rate of the oxygen production system according to whether the pulse rate monitoring value is within the threshold interval.

[0069] That is to say, first determine whether to adjust the oxygen output of the oxygen production system based on whether the blood oxygen saturation monitoring value meets expectations. If the actual monitoring value of the blood oxygen saturation does not meet expectations, the oxygen output of the oxygen production system needs to be increased regardless of whether the pulse rate monitoring value meets expectations. If the actual monitoring value of the blood oxygen saturation meets expectations, further determine whether to adjust the oxygen output of the oxygen production system based on whether the actual monitoring value of the pulse rate is within the expected range. If the actual monitoring value of the pulse rate is within the expected range, reduce the oxygen output of the oxygen production system; otherwise, keep the oxygen output of the oxygen production system unchanged.

[0070] In this solution, the two parameters of blood oxygen saturation and pulse rate are used as the basis for regulating the oxygen output of the oxygen production system. This can not only fully reflect the user's health status, but also adjust the oxygen output of the oxygen production system in time to meet the user's current needs when it is monitored that the user's physical condition does not meet the health requirements, thereby preventing blind adjustment of the oxygen supply from harming the user. At the same time, when it is monitored that the user's physical condition meets the health requirements, the oxygen output of the oxygen production system can be kept unchanged, so as to achieve the purpose of saving power consumption of the oxygen production system.

[0071] It should be noted that adjusting the oxygen output of the oxygen production system may be to synchronously adjust the oxygen production pressure and the oxygen output rate of the oxygen production system, that is, to increase or decrease them synchronously so that the oxygen output reaches the expected value as soon as possible.

[0072] In some embodiments, in order to save power consumption, the physiological parameters of the user of the oxygen production system are monitored in real time, and the oxygen production pressure and oxygen output rate of the oxygen production system are controlled in real time according to the real-time monitoring results, which are changed to periodic monitoring and control, and the control method is changed to step control.

[0073] The periodic monitoring and control includes: Step 4: Execute the above steps 2-3 every preset time period.

[0074] The step-by-step control method includes: the oxygen production pressure and oxygen output rate of the oxygen production system are designed as multi-level control, and the oxygen production pressure and oxygen output rate are controlled to increase or decrease by one level at most in each time period. That is, when the oxygen output does not reach the corresponding rated output maximum value, the oxygen output is controlled to increase by one level at most in each time period; when the oxygen output does not reach the corresponding rated output minimum value, the oxygen output is controlled to decrease by one level at most in each time period.

[0075] The oxygen output at different levels is determined according to the rated output maximum value, the rated output minimum value and the number of levels of the multi-stage control.

[0076] The time period may be set and adjusted based on experience, or may be set and adjusted based on actual needs of a specific user or a specific type of user. For example, the time period may be initially set to 1 minute, and then the monitoring period may be modified to 2 minutes based on user needs.

[0077] The oxygen production pressure and oxygen output rate at different levels can be determined according to their respective rated output maximum values, rated output minimum values ​​and the number of multi-level control levels. For example, when the multi-level control is 8 levels, the difference between the outputs of levels 1 to 8 is set between the rated output minimum values ​​and rated output maximum values ​​of the oxygen production pressure and oxygen output rate, and the output Δ of the i-th level is i for: That is to say, in each time period, for example, every minute, the latest monitoring value is checked to see whether it meets the corresponding expectations. If it does not meet the expectations, the output level is raised or lowered, and the difference between each level is a standard value. If it meets the expectations, the current output level remains unchanged.

[0078] However, the present invention is not limited to this. According to the actual functional requirements of the oxygen production system, the differences between the multi-level outputs of the oxygen production pressure and the oxygen output rate may also be different. For example, the first-level output is the rated output minimum value, the difference between the second level and the first level is a standard value, the difference between the third level and the second level is a multiple of the standard value, the difference between the fourth level and the third level is a multiple of the difference between the third level and the second level, and so on, until the highest-level output is the rated output maximum value.

[0079] In some embodiments, according to different models of oxygen production systems, for example, those specifically used for specific users or specific types of users, initial values ​​of oxygen production pressure and oxygen output rate of the oxygen production system are also set, which can reduce the frequent input of pulse rate and blood oxygen saturation normal value thresholds and further save power consumption.

[0080] In some embodiments, the values ​​set by the user are also used as the initial values ​​of the oxygen production pressure and oxygen output rate of the oxygen production system. For example, the threshold interval of the normal pulse rate is [60, 120], and the threshold of the normal blood oxygen saturation is 95%.

[0081] The present invention provides a controllable oxygen production system, the composition structure of which is as follows: Figure 2 As shown, including:

[0082] Oxygen generation unit;

[0083] The pulse rate and blood oxygen saturation monitoring unit monitors the pulse rate and blood oxygen saturation of the user of the oxygen generation system and outputs the pulse rate monitoring value and the blood oxygen saturation monitoring value;

[0084] The system control unit obtains the threshold interval of the normal pulse rate value and the threshold of the normal blood oxygen saturation value, and controls the oxygen output of the oxygen production unit in combination with the received pulse rate monitoring value and blood oxygen saturation monitoring value, wherein the oxygen output is the oxygen production pressure and / or the oxygen output rate.

[0085] The technical features of the oxygen production system of this embodiment correspond to the embodiment of the control method of the oxygen production system described above, and its technical advantages are the same as those of the above embodiment, which will not be described in detail here.

[0086] In some embodiments, in order to accurately control the oxygen production output rate of the oxygen production system, the control logic of the system control unit is set to:

[0087] When the blood oxygen saturation monitoring value is less than the threshold value, the oxygen production pressure of the oxygen production unit is controlled to increase, and the oxygen output rate of the oxygen production unit is controlled to increase;

[0088] When the blood oxygen saturation monitoring value is greater than or equal to the threshold, it is determined whether to adjust the oxygen production pressure and oxygen output rate of the oxygen production system according to whether the pulse rate monitoring value is within the threshold interval.

[0089] The system control unit controls the oxygen output of the oxygen production unit, which can be:

[0090] If the pulse rate monitoring value is within the threshold range, the oxygen production pressure of the oxygen production unit is controlled to decrease, and the oxygen output rate of the oxygen production unit is controlled to decrease;

[0091] If the pulse rate monitoring value is not within the threshold range, the oxygen production pressure of the oxygen production unit is controlled to remain unchanged, and the oxygen output rate of the oxygen production unit is controlled to remain unchanged.

[0092] In some embodiments, in order to save power consumption, the system control unit periodically obtains the physiological parameters of the user of the oxygen production system, including the pulse rate monitoring value and the blood oxygen saturation monitoring value, and determines the control signal of the oxygen production pressure and oxygen output rate of the oxygen production unit according to the obtained values ​​and the expected values ​​of the user's pulse rate and blood oxygen saturation. Compared with real-time monitoring of the physiological parameters of the user of the oxygen production system and real-time control of the oxygen production pressure and oxygen output rate of the oxygen production system according to the real-time monitoring results, periodic monitoring and control can effectively reduce power consumption. The monitoring period can be set according to the actual situation of the user.

[0093] Specifically, the pulse rate and blood oxygen saturation monitoring unit collects and outputs the pulse rate monitoring value and the blood oxygen saturation monitoring value collected by the monitoring device at every preset time period, and in consideration of changes in the user's basic physical condition, it can also receive and output the threshold interval of the normal pulse rate value and the threshold of the normal blood oxygen saturation value at every other preset time period;

[0094] The system control unit receives the output signals of the pulse rate and blood oxygen saturation monitoring units at preset time intervals, and controls the oxygen output of the oxygen production unit, including the oxygen production pressure and the oxygen output rate, according to the threshold interval, the threshold and the received pulse rate monitoring value and the blood oxygen saturation monitoring value.

[0095] In some embodiments, in order to achieve fine control over the oxygen output, improve the user's comfort, and further reduce power consumption, the control signals of the oxygen production pressure and the oxygen output rate are adjusted in a step-by-step manner.

[0096] Among them, the step-by-step control of the control unit includes: the oxygen production pressure and oxygen output rate of the oxygen production system are designed as multi-level control, and the oxygen production pressure and oxygen output rate are controlled to increase or decrease by at most one level in each time period. That is, in each time period, the system control unit receives the current pulse rate monitoring value and blood oxygen saturation monitoring value once. If the pulse rate and blood oxygen saturation monitoring values ​​both meet the preset corresponding expected values, the oxygen production pressure and oxygen output rate are lowered by one level; if only the blood oxygen saturation monitoring value meets the preset expected value, the current oxygen production pressure and oxygen output rate level are maintained unchanged; if the pulse rate and blood oxygen saturation monitoring values ​​both meet the preset corresponding expected values, the oxygen production pressure and oxygen output rate are lowered by one level.

[0097] It should be noted that, according to different models of oxygen production systems and actual configurations of the oxygen production units of the oxygen production systems, the system control unit may directly control the oxygen production pressure and oxygen output rate of the oxygen production unit through control signals, or the system control unit may also Figure 3 As shown, the control signal is transmitted to the control device of the oxygen production pressure and the oxygen output rate accordingly, and then the oxygen output amount is actually controlled by the control device of the oxygen production pressure and the oxygen output rate respectively.

[0098] In order to enable technicians to more clearly understand how to adjust and control the oxygen output of the oxygen production system during use, the following Figure 3 The present invention introduces how the adjustable oxygen production system of the present invention is combined with an existing oxygen production system and acts on oxygen users.

[0099] In this embodiment, the pulse rate and blood oxygen saturation monitoring unit 200 monitors the actual pulse rate and blood oxygen saturation of the user (i.e., the user of the oxygen production system) in real time or periodically, and transmits the monitored values ​​to the system control unit 100. The system control unit 100 adjusts the oxygen output of the oxygen production unit according to the received monitored values ​​and the expected values ​​of the pulse rate and blood oxygen saturation set for the current user. Figure 3 Only the core component of the oxygen production unit, the adsorption unit 400, is shown. It should be noted that the adsorption unit 400 is not a necessary component of the present application. For oxygen production systems of other signals, it can be replaced by the core component of oxygen production. In this embodiment, after starting the oxygen production system, a gas with a certain pressure and containing oxygen is input into the adsorption unit through a compressor (not shown). The adsorption unit enriches the oxygen in the input gas through an adsorbent and outputs it to the user for use.

[0100] The controllable oxygen production system of the present invention further comprises a pressure generation and control unit 300, an oxygen output and control unit 500, a gas transmission pipeline 600 and a housing 700 on the basis of the previous embodiment. The pressure generation and control unit 300 is used to receive the oxygen production pressure level output by the system control unit 100, and control the pressure of the gas input by the adsorption unit 300, for example, it can be a pressure control signal that converts the oxygen production pressure level into a control valve that acts on the gas input by the adsorption unit; the oxygen output and control unit 500 is used to receive the oxygen output rate level output by the system control unit 100, and control the oxygen output rate of the adsorption unit, for example, it can be a control signal that converts the oxygen output rate level into a control valve that acts on the oxygen output of the adsorption unit; the gas transmission pipeline 600 is used to transmit the oxygen prepared by the oxygen production system to the user; the housing 700 is used to encapsulate the above oxygen preparation and control components.

[0101] In this embodiment, the steps of using the adjustable oxygen production system include:

[0102] When the system is started, the system control unit 100 obtains the currently required oxygen output level and the expected values ​​of the pulse rate and blood oxygen saturation of the current user, and converts the oxygen output level into an oxygen production pressure control signal S1 and an oxygen output control signal S2, and sends them to the pressure generation and control unit 300 and the oxygen output and control unit 500, respectively, so as to provide the user with the corresponding oxygen supply according to the preset level. Among them, the currently required oxygen output level is the initial value of the oxygen production system, which can be a preset value of the system or a value set by the user or manager of the oxygen production system.

[0103] During operation, every other preset time period, the pulse rate and blood oxygen saturation monitoring unit 200 monitors the user's pulse rate and blood oxygen saturation in real time and sends them to the system control unit 100. The system control unit 100 compares the received monitoring values with the preset expected values, and adjusts the magnitudes of the control signals S1 and S2 according to the comparison results. The adjustment basis of the control signals S1 and S2 is shown in Table 1 below:

[0104] Table 1

[0105]

[0106]

[0107] In this embodiment, the user sets the expected value of the pulse rate PR in the range of 60 - 120, and the expected value of the blood oxygen saturation SpO 2 is set to 95%.

[0108] Correspondingly, in this embodiment, the adjustment basis of the pulse rate PR1 and the blood oxygen saturation SpO 2 1 is shown in Table 2 below:

[0109] Table 2

[0110]

[0111] Specifically, when the monitored value PR1 of PR is within the preset expected value range, that is, 60 < PR1 < 120, and the monitored value SpO 2 of SpO 2 1 < 95%, then the pressure control signal S1 increases by a standard amount ΔP, and the oxygen output control signal S2 increases by a standard amount ΔQ. In this embodiment, ΔP is set to 5% and ΔQ is set to 5%. Thereafter, every time a period of time t passes, for example, t is 1 minute, the monitored pulse rate value and blood oxygen saturation value are compared with the corresponding expected values again. If the above judgment result still holds, then continue to increase S1 and S2 by one standard amount ΔP and ΔQ respectively until the monitored PR1 and SpO 2 1 meet the preset expected value range, or S1 and S2 reach the rated maximum output of the system. Continuously monitor whether the pulse rate value and blood oxygen saturation value meet the expectations until the above judgment result no longer holds, and adjust the S1 and S2 signals according to the new judgment result.

[0112] When the monitored value PR1 of PR is within the preset expected value range, and the monitored value SpO 2 of SpO 2 1 is also within the preset expected range. In this embodiment, that is, SpO 21≥95%, the pressure control signal S1 is reduced by a standard amount ΔP, and the oxygen output control signal S2 is reduced by a standard amount ΔQ. After that, after a period of time t, the monitored pulse rate monitoring value and blood oxygen saturation monitoring value are compared with the corresponding expected value again. If the above judgment result is still obtained, S1 and S2 are further reduced by a standard amount ΔP, ΔQ until the monitored PR1 and SpO 2 1 is in line with the preset expected value range, or the S1 and S2 signals reach the minimum output specified by the system. Continue to monitor whether the pulse rate value and blood oxygen saturation value meet the expectations until the above judgment result is no longer valid, and adjust the S1 and S2 signals according to the new judgment result.

[0113] When the PR monitoring value PR1 is not within the preset expected value range and SpO 2 The monitoring value is also not within the preset expected value range, that is, SpO 2 1<95%, the pressure control signal S1 increases by a standard amount ΔP, and the oxygen output control signal S2 increases by a standard amount ΔQ. After a period of time t, the pulse rate monitoring value and blood oxygen saturation monitoring value are compared with the corresponding expected values. If the above judgment result is still obtained, S1 and S2 are increased by a standard amount ΔP and ΔQ respectively until the monitored PR1 and SpO 2 1 meets the preset expected value range, or S1, S2 reaches the rated maximum output of the system. Continue to monitor whether the pulse rate value and blood oxygen saturation value meet the expectations until the above judgment result is no longer valid, and adjust the S1, S2 signals according to the new judgment result.

[0114] When the PR monitoring value PR1 is not within the preset expected value range, that is, PR1>120, or PR1<60, and SpO 2 The monitored value is within the preset expected value range, that is, SpO 2 1≥95%, then S1, S2 signals remain unchanged. After that, every time a period of time t passes, the monitored pulse rate value and blood oxygen saturation value are compared with the corresponding expected values ​​again. If the above judgment result is still the same, S1, S2 signals continue to remain unchanged, and continue to monitor whether the pulse rate monitoring value and blood oxygen saturation monitoring value meet the expectations until the above judgment result is no longer valid, and adjust S1, S2 signals according to the new judgment result.
