Description

Technical Field

[0001] This invention relates to the field of ventilators, and more particularly to a test method and test apparatus for adaptive adjustment parameters of ventilators. Background Technology

[0002] Patent application (publication number CN103908715A) discloses a ventilator device, parameter setting and adjustment method, applicable to emergency care, anesthesia, ICU, and respiratory therapy. The ventilator parameter setting and adjustment method includes steps for setting or adjusting four ventilator parameters: tidal volume (Vt), inspiratory time (Ti), breath-holding time (Tp), and respiratory rate (f). It also includes a step to verify the set or adjusted parameters. If the set or adjusted parameters meet the set constraints, the setting or adjustment is valid; otherwise, the setting or adjustment is rejected and a prompt message is given. When the user sets the above four parameters and they do not meet the constraints, recommended values ​​for the four parameters are given. Disadvantages of the prior art: 1. The above technical solution is only applicable to doctors or users, and not suitable for testers who frequently need to adjust or want to test the maximum or minimum value of a single control parameter. 2. During the testing phase, especially when testers want to test whether adjusting a single control parameter can achieve a preset value, they need to manually adjust several other constraint parameters continuously, reducing work efficiency. 3. When adjusting other control parameters, it is necessary to continuously and manually calculate whether the currently adjusted value satisfies the constraint relationship. This is especially complex and tedious when several parameters need to be adjusted to satisfy one parameter, and it lacks intelligence. 4. When the adjustment cannot satisfy the constraint relationship, only a recommended value is given; in actual operation, it is still necessary to manually adjust other related parameters. Summary of the Invention

[0003] This invention application discloses a testing method and apparatus for adaptive adjustment parameters of a ventilator, which aims to solve the problem of insufficient intelligence in the parameter adjustment of ventilators.

[0004] The technical solution of this invention is as follows:

[0005] A test method for adaptive adjustment parameters of a ventilator includes the following steps:

[0006] Step 1: The tester enters the adaptive adjustment parameter test environment. When the current ventilation mode is determined to be PCV ventilation mode, the constraint relationship formula Paw>10+△int.PEEP+PEEP is called from the constraint relationship table in the background database.

[0007] Step 2: Increase or decrease PEEP. Calculate the current PEEP parameter value under the condition that the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP is satisfied. When PEEP is at its maximum, record and store the maximum critical value of Paw and the maximum critical value of △int.PEEP. When PEEP is at its minimum, record and store the minimum critical value of Paw and the minimum critical value of △int.PEEP.

[0008] Step 3: When Paw is between the minimum and maximum critical values, adjust PEEP and recalculate.

[0009] The values ​​of △int.PEEP and Paw are determined, and the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP is satisfied. PEEP, △int.PEEP and Paw are stored one by one for easy use in subsequent tests.

[0010] Step 4: Exit the adaptive parameter adjustment test environment.

[0011] Where: Paw represents airway pressure, △int.PEEP represents sigh pressure, and PEEP represents positive end-expiratory pressure.

[0012] Furthermore: In step 2, the maximum and minimum critical values ​​of Paw exceed their own limits under the test environment; the maximum and minimum critical values ​​of △int.PEEP exceed their own limits under the test environment.

[0013] Furthermore: In step 1, a password is required to enter the adaptive parameter adjustment test environment; in step 4, a password is required to exit the adaptive parameter adjustment test environment.

[0014] Furthermore, there are voice prompts when entering the adaptive parameter adjustment test environment in step 1 and when exiting the adaptive parameter adjustment test environment in step 4.

[0015] Furthermore, PEEP can be adjusted by the operator triggering buttons on the UI interface.

[0016] Furthermore: In step 3, after adjusting PEEP, the recalculated Paw and △int.PEEP, which correspond one-to-one with PEEP, are communicated to the testers through voice broadcast and text display.

[0017] The present invention also discloses a testing device for adaptive adjustment parameters of a ventilator, comprising:

[0018] The module is used to: when the ventilation mode before the tester enters the adaptive adjustment parameter test environment is determined to be PCV ventilation mode, the module calls the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP from the constraint relationship table in the background database.

[0019] The critical value recording module is used to: increase or decrease PEEP, calculate whether the current PEEP parameter value satisfies the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP, record the maximum critical value of Paw and the maximum critical value of △int.PEEP when PEEP is at its maximum, and record the minimum critical value of Paw and the minimum critical value of △int.PEEP when PEEP is at its minimum.

[0020] The adaptive parameter adjustment module is used to: adjust PEEP when Paw is between the minimum and maximum critical values, recalculate the values ​​of △int.PEEP and Paw, and satisfy the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP. It then stores PEEP, △int.PEEP, and Paw in a one-to-one correspondence for easy use in subsequent tests. The function of calling this module is the same as in step 1, and will not be repeated here.

[0021] Furthermore, the testing device also includes a login / logout module, used for: testers to enter the adaptive parameter adjustment test environment by entering a password, and to exit the adaptive parameter adjustment test environment by entering a password again after completing the parameter test.

[0022] Furthermore, the testing device also includes a voice broadcast module, used for: voice broadcasting when entering and exiting the adaptive adjustment parameter testing environment, and, after adjusting PEEP, broadcasting the recalculated Paw and Δint.PEEP, which correspond one-to-one with PEEP, to the test personnel via voice.

[0023] Furthermore, the testing device also includes a display module for displaying the adjusted PEEP value, as well as the recalculated Paw value and Δint.PEEP value that correspond one-to-one with PEEP.

[0024] The technical effects achieved by this method and apparatus are as follows: When the parametric mode constraint relationship formula Paw > 10 + △int.PEEP + PEEP is met, by adjusting the value of PEEP, the other two values ​​△int.PEEP and Paw also adaptively adjust. That is, adjusting one parameter allows the other two parameters to adjust adaptively, and all three parameters still satisfy the parametric mode constraint relationship formula Paw > 10 + △int.PEEP + PEEP. Therefore, this apparatus and method can achieve the following technical effects:

[0025] 1. When adjusting the control parameter PEEP, under the constraint condition Paw>10+△int.PEEP+PEEP, the values ​​of parameters △int.PEEP and Paw are adaptively adjusted.

[0026] 2. The passively adjusted constraint parameter values ​​△int.PEEP and Paw still satisfy the constraint relationship Paw>10+△int.PEEP+PEEP;

[0027] 3. When frequently adjusting a single parameter PEEP, it cannot be adjusted to the target value due to constraints from other parameters. Adaptive adjustment can quickly and automatically calculate the values ​​of other related parameters △int.PEEP and Paw, satisfying the constraint relationship Paw>10+△int.PEEP+PEEP, and automatically adjust to meet the parameter constraint relationship of active adjustment.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] refer to Figure 1 , Figure 1 A test method for adaptive adjustment parameters of a ventilator is disclosed, including:

[0034] Step 1: Retrieve the parameter mode constraint formula: The tester enters the adaptive parameter adjustment test environment and retrieves the parameter mode constraint formula Paw>10+△int.PEEP+PEEP from the constraint relationship table in the background database. In this step, Paw represents airway pressure, △int.PEEP represents sigh pressure, and PEEP represents positive end-expiratory pressure. Before retrieving the constraint formula Paw>10+△int.PEEP+PEEP from the background database constraint relationship table, it is necessary to first determine that the current ventilation mode is PCV ventilation mode.

[0035] Step 2, Record Critical Values: By increasing or decreasing PEEP, calculate whether the current PEEP parameter value satisfies the parameter mode constraint relationship formula Paw > 10 + Δint.PEEP + PEEP. When PEEP is at its maximum, record and store the maximum critical values ​​of Paw and Δint.PEEP. Similarly, when PEEP is at its minimum, record and store the minimum critical values ​​of Paw and Δint.PEEP. In other words, this step means that when PEEP is at its maximum, according to the formula Paw > 10 + Δint.PEEP + PEEP, Paw is at its maximum; when PEEP is at its maximum, according to the formula Paw > 10 + Δint.PEEP + PEEP, Paw is at its minimum. Therefore, it is easy to understand that when PEEP is at its maximum, given that Paw > 10 + Δint.PEEP + PEEP, both Δint.PEEP and Paw have maximum critical values. When PEEP is set to its minimum, under the condition that Paw > 10 + △int.PEEP + PEEP, both △int.PEEP and Paw have minimum critical values. The maximum and minimum critical values ​​of △int.PEEP and Paw are stored in a critical value storage table. It should be noted that the maximum and minimum critical values ​​of Paw exceed their own limits under the test environment. Similarly, the maximum and minimum critical values ​​of △int.PEEP exceed their own limits under the test environment.

[0036] Additionally, when adjusting PEEP (increasing or decreasing it), based on the existing parameter constraints, set the parameter limit values ​​Paw = 19, △int.PEEP = 5, and PEEP = 3. If PEEP is further adjusted, when PEEP exceeds 3, the increase in PEEP beyond its maximum value will be constrained by the relationship Paw > 10 + △int.PEEP + PEEP, preventing further automatic adjustment. The value of PEEP needs to be manually adjusted to ensure Paw is greater than 19. Alternatively, manual adjustment of PEEP can only continue if △int.PEEP is less than 5.

[0037] Step 3, Adaptive Parameter Adjustment: Within the range of Paw between the minimum and maximum critical values, adjust PEEP, recalculate the values ​​of Δint.PEEP and Paw, and satisfy the parameter mode constraint formula Paw > 10 + Δint.PEEP + PEEP. Store PEEP, Δint.PEEP, and Paw in a one-to-one correspondence for later testing. After determining the minimum and maximum critical values ​​of Paw in Step 2, readjust PEEP within the range of these values, and calculate the corresponding Δint.PEEP and Paw values ​​after each adjustment. In other words, each adjustment of PEEP yields a corresponding Δint.PEEP and Paw, satisfying the parameter mode constraint formula Paw > 10 + Δint.PEEP + PEEP. However, the adjustment range of PEEP can only ensure that the obtained Paw is between the minimum (inclusive) and maximum (inclusive) critical values. Each adjusted PEEP, along with the calculated △int.PEEP and Paw, are recorded as a set of data, allowing for the storage of several sets. These sets can then be directly accessed in subsequent tests.

[0038] Each time a parameter value changes after adaptive adjustment, a prompt message is displayed to inform the tester of the current automatically adjusted value, such as... Figure 2 As shown. In this step, if adjusting parameters requires satisfying two constraint formulas simultaneously, the program first calculates the second formula and then automatically adjusts according to the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP. In other words, if another constraint relationship appears during PEEP adjustment, the other constraint relationship must be satisfied first before satisfying Paw>10+△int.PEEP+PEEP.

[0039] Step 4: After completing Step 3, enter the password and exit the adaptive parameter adjustment test environment. At this point, the entire test process is complete.

[0040] Furthermore, in step 1, a password is required to access the test environment. This password is used to distinguish between the user environment and the test environment. The password in step 1 and the password in step 4 should be the same.

[0041] Furthermore, voice prompts are provided when entering the adaptive parameter adjustment test environment in step 1 and when exiting the adaptive parameter adjustment test environment in step 4, to remind testers to enter and exit the test environment.

[0042] Furthermore, in this application, the parameter PEEP is adjusted by the operator triggering button adjustments on the UI interface, such as... Figure 2 As shown. The trigger button can be adjusted by clicking and dragging the button on the UI interface to continuously increase or decrease the PEEP value; or, testers can directly press and drag the button on the UI interface with their finger to adjust PEEP.

[0043] Furthermore, in step 3, after adjusting PEEP, the recalculated Paw and △int.PEEP, which correspond one-to-one with PEEP, are communicated to the testers via voice announcement and text display.

[0044] refer to Figure 3 The present invention also discloses a testing device for adaptive adjustment parameters of a ventilator, comprising:

[0045] The calling module is used for: testers entering the adaptive parameter adjustment test environment, and calling the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP from the constraint relationship table in the background database.

[0046] The critical value recording module is used to: increase or decrease PEEP, calculate whether the current PEEP parameter value satisfies the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP, record the maximum critical value of Paw and the maximum critical value of △int.PEEP when PEEP is at its maximum, and record the minimum critical value of Paw and the minimum critical value of △int.PEEP when PEEP is at its minimum. The function of the critical value recording module is the same as that in step 2, and will not be repeated here.

[0047] The adaptive parameter adjustment module is used to: adjust PEEP when Paw is between the minimum and maximum critical values, recalculate the values ​​of △int.PEEP and Paw, and satisfy the parameter mode constraint relationship formula Paw>10+△int.PEEP+PEEP. It then stores PEEP, △int.PEEP, and Paw in a one-to-one correspondence for easy use in subsequent tests. The adaptive parameter adjustment module has the same function as step 3, and will not be repeated here.

[0048] Furthermore, the testing device also includes a login / logout module, used for: testers entering a password to enter the adaptive parameter adjustment test environment, and entering the password again to exit the adaptive parameter adjustment test environment after completing the parameter test. This login / logout module is mainly used to distinguish between the test environment and the user environment.

[0049] Furthermore, the testing device also includes a voice broadcast module, used for: voice broadcasting when entering and exiting the adaptive adjustment parameter testing environment, and for broadcasting the recalculated Paw and Δint.PEEP, which correspond one-to-one with PEEP, to the test personnel via voice after adjusting PEEP.

[0050] Furthermore, the testing apparatus also includes: a display module for displaying, for example... Figure 2 The values ​​of PEEP after adjustment are shown, as well as the recalculated values ​​of Paw and △int.PEEP that correspond one-to-one with PEEP.

[0051] Advantages of this device and method:

[0052] When the parametric mode constraint relationship formula Paw>10+△int.PEEP+PEEP is met, by adjusting the value of PEEP, the other two values ​​△int.PEEP and Paw will also adaptively adjust. That is, adjusting one parameter will adaptively adjust the other two parameters, and all three parameters will still satisfy the parametric mode constraint relationship formula Paw>10+△int.PEEP+PEEP. Therefore, this device and method can achieve the following technical effects:

[0053] 1. When adjusting the control parameter PEEP, under the constraint condition Paw>10+△int.PEEP+PEEP, the values ​​of parameters △int.PEEP and Paw are adaptively adjusted.

[0054] 2. The passively adjusted constraint parameter values ​​△int.PEEP and Paw still satisfy the constraint relationship Paw>10+△int.PEEP+PEEP;

[0055] 3. When frequently adjusting a single parameter PEEP, it cannot be adjusted to the target value due to constraints from other parameters. Adaptive adjustment can quickly and automatically calculate the values ​​of other related parameters △int.PEEP and Paw, satisfying the constraint relationship Paw>10+△int.PEEP+PEEP, and automatically adjust to meet the parameter constraint relationship of active adjustment.

[0056] Previously, inspectors or testers had to manually adjust each parameter to ensure it met its maximum and minimum limits. Adjusting one parameter often required manually adjusting three or four others to achieve the desired result. The method and apparatus of this invention allow testers or factory inspectors to easily check whether parameters can be adjusted to their maximum or minimum values ​​during large-scale factory testing in PCV ventilation mode. Only one parameter in the constraint relationship needs adjustment, and the others adjust automatically. This method significantly improves inspection efficiency and increases production capacity.

[0057] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
