As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0035] In the present application, “and / or” refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0036] See also Figure 1 , is a schematic diagram of a breathing control system provided by an embodiment of the present application. Specifically, Figure 1 As shown, the system may include: a ventilator such as a non-invasive ventilator 10 and a server 20. Please refer to Figure 2 , is a structural schematic diagram of a non-invasive ventilator provided by the present application. The non-invasive ventilator 10 comprises a sealing ring 101, a foldable device 102 and a cover 103. The foldable device 102 can be connected to the sealing ring 101 and the cover 103 respectively. The foldable device 102 controls the cover 103 to move away from or approach the sealing ring 101 by stretching or contracting. That is, the foldable device 102 controls the cover 103 to move away from the sealing ring 101 by stretching, and controls the cover 103 to move close to the sealing ring 101 by contracting; wherein,

[0037] The non-invasive ventilator 10 is used to collect identity information and physiological characteristic information of a target user who uses the non-invasive ventilator, wherein the identity information includes any one or more of gender, age, and medical history information, and the physiological characteristic information includes any one or more of blood oxygen concentration, heart rate, respiratory rate, and blood pressure;

[0038] The non-invasive ventilator 10 is further used to send the identity information and the physiological characteristic information of the target user to the server;

[0039] The server 20 is used to receive the identity information and the physiological characteristic information of the target user from the non-invasive ventilator, determine a target parameter model matching the identity information according to the identity information of the target user, and input the physiological characteristic information of the target user into the target parameter model to obtain a target oxygen supply parameter corresponding to the physiological characteristic information of the target user, wherein the target oxygen supply parameter includes at least one oxygen supply concentration and an oxygen supply time corresponding to each oxygen supply concentration; the target parameter model is obtained by training based on each physiological characteristic information corresponding to the identity information matching the identity information of the target user in the historical data and its corresponding oxygen supply parameter;

[0040] The server 20 is further used to send the target oxygen supply parameter to the non-invasive ventilator;

[0041] The non-invasive ventilator 10 is used to receive the target oxygen supply parameter from the server and obtain gas with an oxygen supply concentration corresponding to the target oxygen supply parameter to supply oxygen to the target user.

[0042] Specifically, the server may store multiple parameter models, and the user identity information corresponding to each parameter model may be different. For example, the server may store multiple parameter models corresponding to different age groups, multiple parameter models corresponding to different types of diseases, or parameter models corresponding to different genders, etc., which are not listed here one by one. Thus, the server can use the parameter model corresponding to the age group as the target parameter model based on the received user's identity information, such as the age group to which the age belongs, and input the user's physiological characteristic information into the target parameter model to obtain the oxygen supply parameter, that is, the target oxygen supply parameter. Among them, each parameter model is trained based on the physiological characteristic information under the corresponding user identity information in the historical data and the oxygen supply parameters corresponding to each group of physiological characteristic information.

[0043] In the present application, the information obtained by the non-invasive ventilator can be obtained through components configured in the non-invasive ventilator, or can be obtained through detection equipment connected to the non-invasive ventilator, such as a wearable device, and this application does not limit this.

[0044] Optional, such as Figure 2 As shown, the non-invasive ventilator can be a triangle (the vertices can have amplitudes to improve the fit of the wearer), and buckles are provided at the three vertices of the non-invasive ventilator (i.e., the three vertices of the triangle), and the buckle may include one or more male parts, and / or one or more female parts, and the parts on the buckle at the three vertices are fixedly connected by mutual interlocking. If the buckle is provided with a male part and / or a female part, the male part and / or the female part can be movably provided on the buckle to fix the non-invasive ventilator according to the head size of different users. If the buckle includes multiple male parts and / or multiple female parts, the male parts and female parts on each buckle can be selected for interlocking according to the head size of different users, such as one male part can be interlocked with two female parts.

[0045] Further optionally, the width of the buckle belt is adjustable. This can improve user comfort and prevent the user's head and face discomfort caused by insufficient buckle belt width. For example, the width of the buckle belt can be 2-8 cm (such as 2 cm, 4.5 cm or 6 cm, etc.). The lengths of the buckle belts can be the same or different. For example, the length of each buckle belt can be 6-20 cm (such as 8 cm, 12 cm or 15 cm, etc.), and the positions of the components on the buckle belt (such as the male component and / or the female component) on the buckle belt can be adjusted. Alternatively, the buckle belt can be made of elastic material to improve user comfort.

[0046] Further optional, such as Figure 2As shown, the foldable device can be a triangle, and stretch ropes (or stretch rods or other stretching parts) are respectively arranged on the three sides of the foldable device, one end of the stretch ropes arranged on the three sides is detachably connected to the foldable device, and the other end is fixedly connected to a stretch ring, so as to control the stretching of the foldable device through the stretch ring. This makes it possible to conveniently and quickly realize the stretching or contraction control of the foldable device, so as to better adapt to the face of the user wearing it, enhance the user experience, and improve the oxygen supply effect.

[0047] Optionally, the non-invasive ventilator may be connected to an oxygen regulating device, and the oxygen regulating device is used to adjust the oxygen concentration;

[0048] The non-invasive ventilator is specifically used to receive the target oxygen supply parameter from the server and start the oxygen regulating device to adjust the oxygen concentration through the oxygen regulating device to obtain gas with an oxygen supply concentration corresponding to the oxygen supply parameter to supply oxygen to the target user.

[0049] Further optionally, the non-invasive ventilator may also be connected to an oxygen storage device, and the oxygen storage device is connected to an oxygen regulating device, that is, the non-invasive ventilator may be connected to the oxygen regulating device through the oxygen storage device, and the oxygen storage device is used to store the gas after the oxygen concentration is adjusted by the oxygen regulating device; the target oxygen supply parameter also includes the oxygen supply speed;

[0050] The non-invasive ventilator can be specifically used to receive the target oxygen supply parameter from the server, start the oxygen regulating device to adjust the oxygen concentration through the oxygen regulating device to obtain gas with an oxygen supply concentration corresponding to the target oxygen supply parameter, and transmit it to the oxygen storage device, and the oxygen storage device outputs the gas with an oxygen supply concentration corresponding to the target oxygen supply parameter according to the oxygen supply speed to supply oxygen to the target user.

[0051] Further optionally, the non-invasive ventilator may also be used to obtain the time interval between inhalation and exhalation of the target user, and send the time interval to the server;

[0052] The server may also be used to determine the oxygen supply speed of the non-invasive ventilator according to the time interval between inhalation and exhalation of the target user, and send the oxygen supply speed to the non-invasive ventilator;

[0053] The non-invasive ventilator can be specifically used to receive the target oxygen supply parameter and oxygen supply speed from the server, obtain gas with an oxygen supply concentration corresponding to the target oxygen supply parameter, and output gas with an oxygen supply concentration corresponding to the target oxygen supply parameter at the oxygen supply speed to supply oxygen to the target user.

[0054] Optionally, the foldable device and the sealing ring are connected via a connecting piece, and the connecting piece includes a fastener and a movable device;

[0055] The non-invasive ventilator can also be used to control the opening of the buckle when it is detected that the non-invasive ventilator is in a power-off state, and the movable device drives the foldable device and the cover body to move in a direction away from the sealing ring to open the cover body. This helps to prevent the user from being unable to breathe due to oxygen outage caused by sudden disconnection, thereby improving safety. Alternatively, a backup battery can be set for the non-invasive ventilator in advance. If the power is off, the backup battery can be switched to power the non-invasive ventilator to achieve continuous oxygen supply to the user and ensure the user's breathing safety.

[0056] Further optionally, the foldable device and the sealing ring are connected by a connecting piece, which may be a storage device. An extension belt is arranged in the storage device, one end of the extension belt is connected to the connecting piece, and the other end is connected to the sealing ring. Stretching pieces are respectively arranged on the three sides of the triangle corresponding to the sealing ring. By stretching the stretching pieces, the extension belt can be unfolded, the triangle can be enlarged, and the non-invasive ventilator can be enlarged.

[0057] In some optional embodiments, the server may also be used to detect whether the setting parameters of the non-invasive ventilator (such as the parameters being used) match the parameters recorded by the server at a preset time interval. If they do not match, it indicates that they may have been illegally tampered with, and an alarm may be issued;

[0058] The server can also be used to send the recorded parameters to the non-invasive ventilator when receiving a parameter recovery instruction for the non-invasive ventilator, so as to control the setting parameters of the non-invasive ventilator to be restored to the recorded parameters.

[0059] Specifically, the matching parameters may be certain key indicators, such as oxygen concentration. The key indicators currently used by the non-invasive ventilator and the key indicators recorded by the server may be compared. If the two are the same, it may indicate a match; or, in some embodiments, the difference between the two may be within a preset threshold range to determine a match. Alternatively, in some embodiments, if multiple parameters are to be matched separately, the weight of each parameter may be set separately (the weight of each parameter may be set to be the same or different). By comparing each parameter to see if it matches, if it matches, the weight of the matched parameter is taken, otherwise the weight is 0, and the sum of the weights of each parameter is calculated. If the sum exceeds the preset weight threshold, it can be determined that the setting parameters of the non-invasive ventilator match the parameters recorded by the server, thereby improving the reliability of the matching determination.

[0060] Optionally, the non-invasive ventilator may also be used to collect environmental information of the non-invasive ventilator when detecting that the cover is opened, the environmental information including information of the user who originally wore the non-invasive ventilator, information of the user who opened the cover, and system time when the cover was opened;

[0061] The non-invasive ventilator is also used to send an alarm message to the server, the alarm message is used to indicate that the cover body is opened, and the alarm message includes the environmental information. Therefore, it is possible to determine whether the opening operation is reasonable based on the environmental information, and to promptly discover the unreasonable situation when it is unreasonable, and the environmental information can be retained as evidence. The user's information may include the user's facial image, iris features, voiceprint features, etc. Optionally, the environmental information may also include recording information, department information, etc.

[0062] Optionally, in other optional embodiments, the non-invasive ventilator may be further provided with at least one oxygen input port, each oxygen input port may be respectively connected to an oxygen storage device, each oxygen storage device is respectively connected to an oxygen regulating device, the oxygen regulating device may be used to adjust the oxygen concentration (oxygen supply concentration), the oxygen storage device may be used to store the gas after the oxygen concentration is adjusted by the oxygen regulating device, and the oxygen concentration (oxygen supply concentration) (range) provided by each oxygen input port may be different;

[0063] The non-invasive ventilator 10 may also be used to detect gas composition information of each gas exhaled by the target user, and send the gas composition information to the server, wherein the gas composition information may include any one or more of the content of each gas, the percentage of each gas in all exhaled gases, and the concentration of each gas;

[0064] The server 20 may also be used to receive the gas composition information;

[0065] The server 20 can be specifically used to input the physiological characteristic information and the gas composition information into the target parameter model to obtain the target oxygen supply parameter corresponding to the physiological characteristic information and the gas composition information of the target user, and the target parameter model is trained based on the physiological characteristic information and gas composition information corresponding to the identity information matching the identity information of the target user in the historical data and the corresponding oxygen supply parameter. Optionally, the target oxygen supply parameter can also be used to indicate the target oxygen inlet port of the at least one oxygen inlet port. Alternatively, the server can send a first control instruction to the non-invasive ventilator, and the first control instruction is used to instruct the non-invasive ventilator to supply oxygen to the user through the selected target oxygen inlet port, and the first control instruction can carry the target oxygen supply parameter;

[0066] The non-invasive ventilator can be specifically used to receive the target oxygen supply parameter from the server, and obtain the gas with the oxygen supply concentration corresponding to the target oxygen supply parameter to supply oxygen to the target user. In other words, the non-invasive ventilator can be specifically used to receive the first control instruction of the server, and according to the first control instruction, open the target oxygen input port indicated by the first control instruction and start the oxygen regulating device corresponding to the target oxygen input port to supply oxygen to the user through the target oxygen input port and according to the target oxygen supply parameter. Among them, the oxygen regulating device corresponding to the target oxygen input port is used to adjust the oxygen concentration to obtain the gas with the oxygen concentration corresponding to the target oxygen supply parameter, and transmit it to the oxygen storage device corresponding to the target oxygen input port, and the oxygen storage device supplies oxygen to the user through the target oxygen input port. The target input port can be one or more.

[0067] In some embodiments, the operations of the server may also be performed by a non-invasive ventilator.

[0068] In an optional embodiment, the server can also simulate the user's breathing image based on the physiological characteristic information and gas composition information, and mark abnormal indicators to help doctors or family members understand the patient's current condition more clearly.

[0069] In an optional embodiment, the non-invasive ventilator can also supply oxygen to the user by switching different oxygen supply concentrations and combining the oxygen supply durations of different oxygen supply concentrations, such as supplying oxygen for 2 minutes at oxygen supply concentration 1 and supplying oxygen for 5 minutes at oxygen supply concentration 2 as a cycle. This makes the oxygen supply more flexible, improves the oxygen supply effect, and helps save oxygen. The switching scheme can be determined based on the user's physiological characteristics information, the user's exhaled gas composition information and / or the user's identity information. For example, the corresponding relationship between the physiological characteristics information and the gas composition information and the switching scheme can be preset; or multiple sets of switching schemes can be pre-set, and the user's physiological characteristics information, gas composition information, etc. can be monitored. According to the monitoring results, a switching scheme is determined from the multiple switching schemes to achieve oxygen supply to the user, and so on. They are not listed here one by one.

[0070] Optionally, the server or non-invasive ventilator can obtain the volume of gas stored in the oxygen storage device (for example, the volume is determined based on the speed at which the oxygen regulating device inputs gas to the oxygen storage device and the duration of the input). When it is detected that the volume of gas stored in the oxygen storage device exceeds a preset first volume threshold, the server or non-invasive ventilator can control the oxygen regulating device corresponding to the oxygen storage device to stop working and no longer deliver gas to the oxygen storage device. Further optionally, if it is detected that the volume of gas stored in the oxygen storage device is lower than a preset second volume threshold, the oxygen regulating device corresponding to the oxygen storage device can be controlled to restart and deliver gas to the oxygen storage device. This helps to improve the reliability of oxygen supply to users. Among them, the first volume threshold is greater than the second volume threshold, and the first volume threshold is less than the capacity of the corresponding oxygen storage device. The capacity of each oxygen storage device can be the same or different. For example, the usage frequency of gases of various oxygen supply concentrations can be determined based on the oxygen supply concentration records of each user in the historical database, and each oxygen storage device can be set according to the usage frequency corresponding to each oxygen supply concentration. The capacity of the oxygen storage device corresponding to the gas with a high usage frequency is greater than the capacity of the oxygen storage device corresponding to the gas with a low usage frequency. That is, the higher the usage frequency corresponding to a gas, the larger the capacity of the oxygen storage device corresponding to the gas.

[0071] Optionally, the at least two oxygen input ports may be provided on the cover body. Further optionally, each oxygen input port may be provided with a sliding cover that matches its shape and size. Then the non-invasive ventilator may be specifically used to control the opening of the sliding cover corresponding to the target oxygen input port upon receiving the first control instruction, so as to supply oxygen to the user through the target oxygen input port. For example, the non-invasive ventilator includes three oxygen input ports, namely oxygen input port 1, oxygen input port 2 and oxygen input port 3, and each input port may be provided with a corresponding sliding cover.

[0072] In some optional embodiments, the opening sizes of different oxygen inlets can be set to be different, for example, the opening of the oxygen inlet with a high oxygen concentration is larger than the opening of the oxygen inlet with a low oxygen concentration, and the opening of the oxygen inlet with a specific oxygen concentration (such as the oxygen concentration suitable for emergency treatment or the oxygen concentration with the highest frequency of use calculated based on historical data) is set to the maximum, so that in an emergency, gas with a high oxygen concentration (or a specific oxygen concentration) can be quickly supplied to the user; and / or, the opening shapes of different oxygen inlets can be different, so that medical staff can quickly identify the currently used oxygen concentration (oxygen supply concentration). For example, the shapes of oxygen inlet 1 and oxygen inlet 2 are different, and the sizes of the three oxygen inlet ports are different, for example, the diameter of the circular inlet of oxygen inlet 1 is 0.6-1.2 cm (for example, 0.7 cm, 0.9 cm or 1.1 cm, etc.), the elliptical transverse diameter (longer diameter) of oxygen inlet 2 is 2.8-3.4 cm (for example, 2.8 cm, 3.1 cm or 3.3 cm, etc.), and the diameter of the circular inlet of oxygen inlet 3 is 2.7-3.3 cm (for example, 2.7 cm, 2.8 cm or 3.2 cm, etc.). Slide covers 1, 2 and 3 can be respectively provided on the oxygen inlet 1, oxygen inlet 2 and oxygen inlet 3, and the size of the opening can be further adjusted through the corresponding slide covers.

[0073] In some optional embodiments, the server may be further configured to determine a flow rate of the gas at the target oxygen inlet port (hereinafter referred to as a first flow rate) based on the physiological characteristic information and the gas composition information of each gas, and control an opening size of the sliding cover corresponding to the target oxygen inlet port based on the determined flow rate; and / or, the server may be further configured to determine a flow rate of the gas at the target oxygen inlet port based on the physiological characteristic information and the gas composition information of each gas, and control a speed at which the oxygen regulating device corresponding to the target oxygen inlet port transmits gas to the corresponding oxygen storage device (hereinafter referred to as a second flow rate) and / or a speed at which the oxygen storage device transmits gas to the target oxygen inlet port (hereinafter referred to as a third flow rate) based on the determined flow rate. The determined flow rate of the gas may be a flow rate level, a flow rate value, or other identification information for indicating the flow rate. For example, the correspondence between each physiological characteristic information, each gas composition information, and the flow rate may be preset, so that the server can determine the first flow rate according to the physiological characteristic information, the gas composition information, and the correspondence, and then control the opening size of the slide cover corresponding to the target oxygen inlet and / or the second flow rate and / or the third flow rate according to the first flow rate. Optionally, the correspondence between the first flow rate and the opening size of the slide cover may be preset, and / or the correspondence between the first flow rate and the second flow rate may be preset, and / or the correspondence between the first flow rate and the third flow rate may be preset, so as to determine the opening size of the slide cover corresponding to the target oxygen inlet and / or the second flow rate and / or the third flow rate according to each correspondence. Furthermore, when controlling the opening size of the slide cover corresponding to the target oxygen inlet port according to the determined flow rate, a second control instruction may be used to send information about the opening size of the slide cover to the non-invasive ventilator, or the information about the opening size of the slide cover may be carried in the first control instruction, etc., so that the non-invasive ventilator can obtain the opening size of the slide cover corresponding to the target oxygen inlet port and control the opening to be at the opening size; or the server may directly control the opening size of the slide cover corresponding to the target oxygen inlet port to open at the opening size corresponding to the flow rate.

[0074] In some optional embodiments, the server may also be used to determine the flow rate of the gas at the target oxygen inlet according to the time interval between the user's inhalation and exhalation, and control the opening size of the slide cover according to the determined flow rate; and / or, the server may also be used to determine the flow rate of the gas at the target oxygen inlet according to the time interval between the user's inhalation and exhalation, and control the speed at which the oxygen regulating device corresponding to the target oxygen inlet transmits gas to the corresponding oxygen storage device and / or the speed at which the oxygen storage device transmits gas to the target oxygen inlet according to the determined flow rate. The determined flow rate of the gas may be a flow rate level, a flow rate value, or other identification information for indicating the flow rate. For example, the corresponding relationship between each time interval and the first flow rate may be pre-set, so that the server can obtain the time interval between the user's inhalation and exhalation, determine the first flow rate according to the corresponding relationship, and then control the opening size of the slide cover corresponding to the target oxygen inlet and / or the second flow rate and / or the third flow rate according to the first flow rate.
