In all of the examples shown and discussed herein, any specific values are to be construed as illustrative only and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that similar reference numerals and letters indicate similar items in the following figures, and therefore, once an item is defined in one figure, it is not required to be further discussed in the subsequent figures.

In order to solve the problem that the modification of the positive pressure ventilation treatment parameter is not intuitive and the professional requirement is high, the present invention provides a method for adjusting the positive pressure ventilation treatment parameter. As shown in FIG. 1, the method of the present invention includes the following steps. :

Step S1: Obtain the current value of the treatment parameter.

The current value of the treatment parameter is updated in real time according to the adjustment of the treatment parameter by the user. In order to facilitate management, acquisition, and update of the treatment parameter, a list of treatment parameters may be maintained, and corresponding treatment parameters are recorded in the list. The current value, such that when updating the value of the treatment parameter, simply change the current value in the list to the updated value, and when the current value of the treatment parameter is obtained, it can be directly looked up from the list.

Wherein, the current value of the treatment parameter at the time of starting up, that is, the initial value of the treatment parameter, can be obtained according to the setting by sending a request for obtaining the value of the treatment parameter to the corresponding positive pressure ventilation therapy machine by means of wired or wireless connection. To obtain the initial value of the treatment parameter from the positive pressure ventilation therapy machine; or, to find the latest value of the treatment parameter at the last shutdown as the initial value of the treatment parameter in the stored treatment parameter list; or, to obtain the default value of the treatment parameter The numerical value is used as the initial value of the treatment parameter, and the like, which is not specifically limited in the embodiment of the present invention.

The treatment parameters will vary according to different positive pressure ventilation modes, for example, for single-level positive pressure ventilation, the treatment parameters include, but are not limited to, treatment pressure and expiratory decompression; for bi-level positive pressure ventilation, the Treatment parameters include, but are not limited to, inspiratory pressure, expiratory pressure, expiratory decompression, inspiratory time, expiratory time, ascending time from expiratory pressure to inspiratory pressure, ascending time from inspiratory pressure to expiratory pressure, Inspiratory pressure trigger sensitivity, and exhalation pressure trigger sensitivity.

Step S2: Draw a waveform according to the current value of the treatment parameter and display the output amount with time by the display device for the user to adjust the waveform.

The output is a variable for reflecting the positive pressure ventilation condition, including the output pressure, and may also include air flow, aeration, and the like.

Figure 2 is the waveform of output pressure and airflow of single-level positive pressure ventilation with time. Figure 3 is the waveform of output pressure and airflow of bi-level positive-pressure ventilation with time. The vertical axis on the left represents the flow value. The vertical axis on the right side represents the pressure value, the horizontal axis represents the time, the broken line represents the waveform of the output pressure as a function of time (hereinafter referred to as the pressure waveform), and the solid line represents the waveform of the flow of the air flow with time (hereinafter referred to as the flow waveform). Based on these waveforms, the user can visually observe whether the corresponding output meets the usage requirements, thereby enabling the user to intuitively adjust the corresponding waveform according to the usage requirements.

Step S3: It is detected whether the above waveform has been adjusted, and if so, step S4 is performed, and if not, step S3 is continued.

Whether the detected waveform has been adjusted in this step may include at least one of the following methods:

Method 1: Detect whether the effective adjustment point on the waveform has been effectively dragged, and if so, determine that the waveform has been adjusted.

Here, an effective adjustment point that is easy for the user to understand and operate, and a corresponding effective drag mode can be set according to the output amount corresponding to the waveform.

Taking the pressure waveform shown by the broken line in FIG. 2 as an example, all the points of the suction section L1 can be set as an effective adjustment point for adjusting the output pressure value, and the corresponding effective drag mode is set to generate upward. Or drag down, so that as long as it detects that the user drags any point of the inspiratory segment L1 up or down by mouse, finger, touch pen, etc., it can be determined that the user adjusts the pressure waveform and can according to the drag end point. A waveform parameter of the adjusted waveform is determined. For the effective adjustment point, the adjusted waveform parameter is an output pressure value, and the treatment pressure in the treatment parameter can be determined by the output pressure value.

Still taking the pressure waveform shown by the broken line in FIG. 2 as an example, the point on the middle position of the exhalation section L2 (the intermediate position can correspond to a range) can be set as an effective adjustment for adjusting the expiratory pressure reduction setting. Point and set the corresponding effective drag mode to generate a downward drag, so as long as it detects that the user drags down the effective adjustment point for adjusting the expiratory pressure reduction setting by a mouse, a finger, a touch pen or the like, It can be determined that the user adjusts the pressure waveform, and the minimum value of the expiratory decompression can be determined according to the end point of the drag. FIG. 4 shows the waveform diagram of adjusting the expiratory decompression setting by the pressure waveform, wherein the left side of the figure is vertical. The axis represents the flow value, the right vertical axis represents the pressure value, and the horizontal axis represents the time. In between, the dotted line is the pressure waveform, and the solid line is the flow waveform.

Taking the pressure waveform shown by the broken line in FIG. 3 as an example, all the points on the horizontal line of the inhalation section or all the points except the end points a and b on the horizontal line of the inhalation section can be set to be used for adjustment. The effective adjustment point of the inspiratory pressure, and set the corresponding effective drag mode to generate an upward or downward drag, so as to detect that the user drags up or down by a mouse, a finger, a touch pen, etc., for example, a point c At this time, it can be determined that the user adjusts the pressure waveform, and the inspiratory pressure value of the adjusted waveform can be determined according to the end point of the drag. It is also possible to set the end point a on the horizontal line of the inspiratory section to be an effective adjustment point for adjusting the rise time of the exhalation air pressure to the suction air pressure, and set the corresponding effective drag mode to generate a leftward or rightward drag. In this way, as long as it is detected that the user drags the point a to the left or right by a mouse, a finger, a touch pen, or the like, it can be determined that the user adjusts the pressure waveform, and the rising section of the adjusted waveform can be determined according to the dragging end point. The slope, in turn, determines the rise time of the expiratory pressure to the inspiratory pressure based on the adjusted waveform. It is also possible to set the end point b on the horizontal line of the inspiratory section to be an effective adjustment point for adjusting the inhalation pressure to the falling time of the expiratory pressure, and set the corresponding effective drag mode to generate a leftward or rightward drag. In this way, as long as it is detected that the user drags the point b to the left or right by a mouse, a finger, a touch pen, or the like, it can be determined that the user adjusts the pressure waveform, and the descending segment of the adjusted waveform can be determined according to the end point of the drag. The slope, in turn, determines the drop time of the suction pressure to the expiratory pressure based on the adjusted waveform. It is also possible to set the end points d, f on the horizontal axis to be effective adjustment points for adjusting the inspiratory time and the exhalation time, respectively, and to set the corresponding effective drag mode to drag left or right, so that As long as it is detected that the user drags the points d and e to the left or right by a mouse, a finger, a touch pen, etc., it can be determined that the user adjusts the pressure waveform, and the inhalation time of the adjusted waveform can be determined according to the end point of the drag. Exhale time. It is also possible to set the point on the middle position of the exhalation section (the intermediate position can correspond to a range) to be an effective adjustment point for adjusting the expiratory pressure reduction setting, and set the corresponding effective drag mode as the generation direction. Drag down, so that as long as the user is detected to drag down by a mouse, a finger, a touch pen, etc., for example, a point e, it can be determined that the user adjusts the pressure waveform, and the minimum of expiratory decompression can be determined according to the end point of the drag. value. In addition, it is also possible to set an effective adjustment point and an effective drag mode corresponding to the setting of the inspiratory pressure trigger sensitivity and the expiratory pressure trigger sensitivity for the pressure waveform shown in FIG. 3.

Here, in order to facilitate the user to know the effective adjustment points so that the user can quickly perform effective adjustment, the method of the present invention may further include: highlighting the set effective adjustment point on the waveform by the display device, the highlighting The manner of the present invention is, for example, a method of changing colors, highlighting, superimposing a circle, and the like, which is not limited by the embodiment of the present invention.

Method 2: Check whether the waveform is replaced with other similar waveforms pre-stored in the waveform library. If yes, it is determined that the waveform has been adjusted. Among them, the similar waveforms in other similar waveforms represent waveforms corresponding to the same output, and other similar waveforms. The other indicates that there is at least one different waveform parameter between the replacement waveform and the replaced waveform.

This embodiment requires a waveform library to be created in advance, and a waveform with a higher usage rate is stored in the waveform library according to medical practice for the user to select. Here, in the embodiment in which the first mode and the second mode are used in combination, if the user uses the adjusted waveform to use the adjusted time to reach the set time, the waveform adjusted by the user through the mode 1 can be stored in the waveform gallery. In order to enable mode two to support user customization mode.

Step S4: Calculate the value of the treatment parameter related to the corresponding waveform according to the adjusted waveform.

Since the waveform of the output is determined based on at least one of the treatment parameters, the value of the treatment parameter associated therewith can also be determined by the waveform.

In addition, the step S4 may specifically include the following steps:

Step S401: Acquire waveform parameters of the adjusted waveform.

Step S402: Calculate the value of the treatment parameter related to the corresponding waveform according to the waveform parameter of the adjusted waveform.

Step S5: The current value of the treatment parameter related to the corresponding waveform is updated to the calculated value, and then step S1 is performed.

After the adjustment of the treatment parameter is completed by step S5, the latest value of the treatment parameter can be sent to the positive pressure ventilation treatment machine by the following step S6, so that the positive pressure ventilation treatment machine can achieve the adjustment of the corresponding output amount.

Step S6: The latest value of the updated treatment parameter is sent to the positive pressure ventilation therapy machine by means of a wired or wireless connection.

The wired connection is, for example, a network cable or various data lines, such as a WIFI connection, a Bluetooth connection, a Near Field Communication (NFC), and the like.

It can be seen that the method of the present invention supports the user to modify the treatment parameter by adjusting the waveform of the output amount changing with time. Here, since the waveform can reflect the corresponding output amount with time, the user can intuitively Adjusting the corresponding waveform for the requirement of the output, and then modifying the relevant treatment parameters by adjusting the waveform without understanding the meaning of each treatment parameter, which is compared with the prior art to obtain the output that meets the requirements by directly modifying the treatment parameters. The method obviously improves the intuitiveness, effectiveness and convenience of the modification, thereby reducing the error rate during the adjustment.

In order to enable the user to visually see the specific values of the treatment parameters related to the waveform, and thus visually reflect the change of the treatment parameters following the waveform, in a specific embodiment of the present invention, the method of the present invention may further include: While the device displays the waveform of the output as a function of time, the current value of the treatment parameter associated with the waveform is also displayed by the display device. For example, the waveform can be displayed on the right side of the screen by the display device, and the current value of the treatment parameter associated with the waveform can be displayed on the left side of the screen.

In order to improve the security of the method of the present invention, in a specific embodiment of the present invention, as shown in FIG. 5, after performing the above step S4, the method of the present invention first performs the following step S7, and then according to the judgment result of step S7. Whether to perform the above step S5, the step S7 is specifically: determining whether the calculated value is within the corresponding effective range, and if yes, performing step S5, otherwise the adjustment of the waveform will be ignored, wherein the effective range may be according to the corresponding treatment A reasonable range setting of the parameters.
