Various embodiments of the present invention will be described below with reference to the drawings. These embodiments are merely exemplary and are not intended to limit embodiments of the present invention.
Example 1
This embodiment 1 provides a method for detecting respiration. The method may be used to generate a specified type of gas and provide the gas to a user's gas supply, which may be, for example, an oxygen generator, an atomizer, or the like.
Fig. 1 is a schematic diagram of a respiration detection method according to the present embodiment. As shown in fig. 1, the method includes:
and 102, judging whether the user is in an inspiration state or not according to the air pressure value and the air pressure change degree in the air delivery device.
In the above method of the present embodiment, whether the user is in an inhalation state is determined according to the air pressure value and the degree of change in air pressure in the air delivery device, and whether to supply air to the user can be controlled based on the state of the user, whereby the air supply efficiency can be improved. Further, the inspiratory status of the user can be determined with high accuracy by comprehensively considering the relationship between the two factors and the respiratory status of the user, not only by the detected air pressure value in the air delivery device, but also by the degree of change in the air pressure.
In this embodiment, the gas delivery device is a device that provides gas to a user. For example, it may be an air delivery tube or mask. Specifically, the gas to be delivered may be oxygen gas, gas for atomization, or the like. The embodiment is not limited to this, and the specific type of the gas transmission device can be selected according to actual needs.
In step 101, the air pressure in the air delivery device may be detected by providing a pressure detection means such as a pressure sensor in the air delivery device.
In step 102, the degree of change in the air pressure may be expressed using any index that characterizes the change in the air pressure.
For example, the degree of change in air pressure may be a slope of the air pressure value within the air delivery device. Here, the slope of the air pressure value in the air delivery device is the amount of change in the air pressure value in the air delivery device per unit time. The slope of the air pressure value in the air conveying device can be a slope value calculated according to the air pressure values in the air conveying device corresponding to different time points; or may be a weighted average of a plurality of slope values calculated from the air pressure values in the gas delivery device at different points in time, wherein the weights used for weighting may be determined from experimental data.
The above description is only an example, and the present embodiment is not limited to the slope of the air pressure value in the air delivery device as the air pressure change degree, and the air pressure change degree may be a change amount of the air pressure value within a predetermined time in the air delivery device, a change time corresponding to a unit air pressure change amount in the air delivery device, or the like.
In one embodiment, if the degree of change in the air pressure is less than a first predetermined threshold value and the air pressure value is less than the standard atmospheric pressure, it is determined that the user is in an inhalation state.
In another embodiment, if the degree of change in the air pressure is greater than or equal to a first predetermined threshold value and less than a second predetermined threshold value, and the average of the plurality of measurements of the air pressure value is less than a third predetermined threshold value, it is determined that the user is in an inspiratory state.
The two embodiments can be executed independently or in combination. That is, the determination may be performed by either one of the embodiments, or may be performed by both embodiments. In the case of adopting both the two embodiments, the execution order of the two embodiments is not limited, that is, the two embodiments may be executed in parallel, or may be executed sequentially, and the order is not limited.
By comparing the degree of change in the air pressure with the first threshold value and/or the second threshold value, it is possible to classify the user based on the degree of inhalation intensity of the user, and to compare the air pressure value with the correlation value based on the classification result, whereby it is possible to set the determination conditions of the inhalation state that are in accordance with the characteristics thereof for the user who has inhaled intensely and the user who has inhaled shallowly, respectively, thereby improving the accuracy of the determination result.
In this embodiment, the pressure sensor may measure the air pressure in the air delivery device a plurality of times, and the measured values obtained by the plurality of times of measurement may be averaged to obtain the average value of the plurality of times of measurement of the air pressure value in step 101. The influence of short-term sudden fluctuations in the gas pressure in the gas delivery device on the measured values can thereby be reduced. The number of measurements may be arbitrarily determined according to actual needs, for example, 3 times, 4 times, 5 times, and the like, but the embodiment is not limited thereto.
In this embodiment, the first, second and third thresholds may be set according to actual conditions. For example, the first threshold value may be set based on a statistical value of the degree of change in air pressure when a user inhales with an inhalation intensity greater than or equal to a predetermined intensity, the second threshold value may be set based on a statistical value of the degree of change in air pressure when a user inhales with an inhalation intensity less than a predetermined intensity, and the third threshold value may be set based on a statistical value of the air pressure when a user inhales with an inhalation intensity less than a predetermined intensity. Here, the intensity of inhalation refers to the intensity of inhalation. Thus, the first threshold corresponds to the degree of change in air pressure when the user inhaling more intensely breathes in, and the second threshold corresponds to the degree of change in air pressure when the user inhaling less intensely breathes in.
By setting the threshold value in this manner, the set threshold value can be matched with an objective statistical result, and therefore, the accuracy of the determination result can be further improved.
In one embodiment, the first threshold value may be set, for example, in a range of-300 Pa/sec (pascal/second) to-90 Pa/sec, the second threshold value may be set, for example, in a range of-89 Pa/sec to-40 Pa/sec, and the third threshold value may be set, for example, in a range of-39 Pa to-10 Pa. By setting the first, second, and third thresholds in this manner, the state of inhalation can be determined with high accuracy. However, the present embodiment is not limited to this, and the above value range may be appropriately modified as needed in actual circumstances.
In the above embodiment, the normal atmospheric pressure may be obtained by any means. For example, it may be set in advance, or may be obtained by measuring using a pressure sensor disposed in the outside air environment or a pressure sensor disposed inside the air supply apparatus.
In the case where the standard atmospheric pressure is obtained by measurement, the standard atmospheric pressure may be an atmospheric pressure value obtained by one measurement or may be an average value of a plurality of measurements of the atmospheric pressure. That is, the atmospheric pressure may be measured by the pressure sensor a plurality of times, and the measurement values obtained by the plurality of times of measurement may be averaged to obtain an average value of the plurality of times of measurement. Thereby, the influence of short-term sudden fluctuations in atmospheric pressure on the measurement value can be reduced. The number of measurements can be determined according to actual needs, for example 5.
In this embodiment, the standard atmospheric pressure may be detected in advance, or may be detected in real time before the comparison is performed each time the standard atmospheric pressure is used. By detecting the standard atmospheric pressure in real time, more accurate current standard atmospheric pressure can be obtained, and therefore the accuracy of a judgment result is improved.
Fig. 2 is another schematic diagram of the respiration detection method according to the embodiment. As shown in fig. 2, the method includes:
in step 206, it is determined that the user is not in an inspiratory state.
In fig. 2, the steps 201 and 204 are executed according to the sequence shown in the figure, but the execution manner is only an example, and the embodiment is not limited thereto, and the execution sequence of the steps 201 and 204 is not limited as long as the judgment results of "whether the air pressure change degree is smaller than the preset first threshold and the air pressure value is smaller than the standard atmospheric pressure" and "whether the air pressure change degree is larger than the preset first threshold and smaller than the preset second threshold and the multiple measurement average of the air pressure value is smaller than the preset third threshold" can be obtained.
The present embodiment is not limited to the above two embodiments for determining whether the user is in the inhalation state, and the above embodiments may be simply modified and/or expanded.
Through the breath detection method of the embodiment, whether the user is in the inspiration state can be judged according to the air pressure value and the air pressure change degree in the air delivery device, so that whether the air is provided for the user can be controlled based on whether the user is in the inspiration state, the air supply efficiency can be improved, the volume of the air supply equipment can be reduced, the production cost of the air supply equipment is reduced, and the carrying by the user is facilitated.
Example 2

Fig. 3 is a schematic view of the gas supply method of the present embodiment. As shown in fig. 3, the method includes:
and step 303, if the user is determined to be in the inspiration state, opening a conveying passage of the gas conveying device so that the gas is provided to the user through the gas conveying device.
By the method of the embodiment, whether the user is in the air suction state is judged according to the air pressure value and the air pressure change degree in the air delivery device, and the air is provided for the user under the condition that the user is in the air suction state, so that the air supply efficiency can be improved, the volume of the air supply equipment can be reduced, the production cost of the air supply equipment is reduced, and the air supply equipment is convenient to carry by the user. Further, the inhalation state of the user can be determined with high accuracy.
In this embodiment, the gas transmission device is the same as the gas transmission device in embodiment 1, and the implementation manners of the steps 301 and 302 are the same as those of the steps 101 and 102 in embodiment 1, and are not described again here.
In step 303, if it is determined that the user is in the inhalation state, the valve capable of opening and closing the delivery passage of the gas delivery device is controlled to open the delivery passage of the gas delivery device, so that the gas is provided to the user through the gas delivery device.
In this embodiment, when it is determined in step 302 that the user is not in the inhalation state, the delivery passage of the gas delivery device is closed, and the above-described step 301 may be continuously executed. Thus, it is possible to improve gas supply efficiency and reduce the volume of the gas supply apparatus by not supplying gas to the user when the user does not inhale.
In this embodiment, the method may further include:
determining an opening time of the conveying path;
maintaining the open state of the transportation path for the open time when it is determined that the user is in the inhalation state; and
when the opening time is reached, the conveying passage is closed, the air pressure of the air conveying device is detected, whether the user is in an inhalation state is judged according to the air pressure value and the air pressure change degree in the air conveying device, and when the user is judged to be in the inhalation state, the conveying passage is opened so that the air is provided for the user through the air conveying device.
In this way, even when the one-time inhalation time of the user is long and longer than the set opening time, the delivery passage of the gas delivery device can be opened a plurality of times by determining the inhalation state a plurality of times within the inhalation time of the user, thereby ensuring that sufficient gas is supplied to the user.
The opening time may be preset or may be determined in real time based on the air pressure in the air storage part of the air supply apparatus.
In one embodiment of this embodiment, the timing may be started when the step 303 is completed, the open state of the gas transmission path is maintained until the timing result reaches the open time, the gas transmission path is closed when the timing result reaches the open time, and the step 301 and the step 303 are executed again after returning to the step 301. If it is determined in step 302 that the user is not currently inhaling, the closed state of the gas delivery passage is maintained; if it is determined in step 302 that the user is still inhaling, the transportation path is opened again.
According to the gas supply method, whether the user is in the air suction state or not is judged according to the air pressure value and the air pressure change degree in the gas transmission device, and whether the gas is supplied to the user or not is controlled based on whether the user is in the air suction state or not, so that the gas supply efficiency can be improved, the volume of the gas supply equipment can be reduced, the production cost of the gas supply equipment is reduced, and the gas supply equipment is convenient to carry.
