Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an offline control method and device for medical equipment. Background Art

[0002] Inhalation therapy is to supply medical gases to patients through ventilators and other equipment to achieve medical effects. Taking nitric oxide gas as an example, inhaled nitric oxide will inhibit the production of endogenous nitric oxide. If the delivery (inhalation) of exogenous nitric oxide is suddenly stopped, the body cannot immediately secrete enough endogenous nitric oxide, which will lead to very serious pulmonary vasoconstriction, increased pulmonary artery pressure, and even pulmonary hypertension crisis. Clinically, it is called "rebound phenomenon". In clinical practice, in order to avoid the "rebound phenomenon" as much as possible, the nitric oxide offline process (some manufacturers' equipment also call it "withdrawal") is very cumbersome. Medical staff need to frequently adjust the concentration of exogenous inhaled nitric oxide, which is time-consuming and laborious. Moreover, during the entire operation process, due to factors such as insufficient manpower and hospital handovers, it cannot be guaranteed that the offline process is strictly executed in accordance with the standardized process, which is very arbitrary and reduces the accuracy of control.

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Inhalation therapy is to supply medical gases to patients through ventilators and other equipment to achieve medical effects. Taking nitric oxide gas as an example, nitric oxide has been found in recent years to play a role in transmitting important information and regulating cell functions in the human body. It can help promote blood circulation in the body. It can quickly diffuse through biological membranes without any intermediary mechanism and transmit the information generated by a cell to the cells around it. Nitric oxide has the characteristics of multiple biological functions and is very easy to participate in the transfer of electron reactions and join the body's redox process. Direct inhalation of nitric oxide therapy can be used as a treatment for persistent pulmonary hypertension in newborns, and it has been proven to improve the body's oxygenation capacity and reduce the high-risk extracorporeal cardiopulmonary support therapy for critically ill patients. Artificial administration of appropriate and controlled nitric oxide can specifically reduce pulmonary hypertension and improve oxygenation. At present, nitric oxide inhalation therapy has been widely used in neonatal respiratory medicine, and is also suitable for clinical medicine fields such as critical care, cardiothoracic vascular surgery, respiratory medicine and anesthesia.

[0038] Inhaled nitric oxide will inhibit the production of endogenous nitric oxide. If the delivery (inhalation) of exogenous nitric oxide is suddenly stopped, a "rebound phenomenon" will occur. To prevent this phenomenon from occurring, when stopping the inhaled nitric oxide treatment, the concentration of exogenous inhaled nitric oxide needs to be gradually reduced to allow the body to have an adaptation process and gradually increase the secretion of endogenous nitric oxide. In clinical practice, in order to avoid the "rebound phenomenon" as much as possible, medical staff need to frequently adjust the concentration of exogenous inhaled nitric oxide, which is cumbersome, time-consuming and laborious. Moreover, during the entire operation process, it is difficult to ensure the accuracy of control due to factors such as insufficient manpower and hospital handovers; more importantly, in order to ensure safety during the entire offline process, the clinic basically adheres to the principle of preferring safety over time, which increases the time of nitric oxide treatment for patients, thereby increasing the cost of treatment and increasing the medical burden. Based on this, an embodiment of the present invention provides an offline control method and device for medical equipment, which can be applied to applications that require intelligent offline control of medical equipment.

[0039] To facilitate understanding of this embodiment, firstly, an offline control method of a medical device disclosed in an embodiment of the present invention is introduced. Figure 1 As shown, the method comprises the following steps:

[0040] Step S102, obtaining the current therapeutic gas concentration and preset time period output by the medical device;

[0041] The above-mentioned therapeutic gas can be a gas used in medical treatment, such as nitric oxide; the above-mentioned preset time period can be set according to actual needs, for example, the range of the preset time period can be 1 minute to 10 hours, and the preferred range can be 0.1 hours to 4 hours; in actual implementation, in order to realize the intelligent offline of the medical equipment, it is necessary to first obtain the current therapeutic gas concentration and preset time period output by the medical equipment.

[0042] Step S104, adjusting the current therapeutic gas concentration based on the preset time period to obtain an adjusted therapeutic gas concentration;

[0043] In actual implementation, if the above-mentioned preset time period is relatively short, such as 1 minute, the therapeutic gas concentration can be adjusted every 1 minute to obtain the adjusted therapeutic gas concentration; if the preset time period is relatively long, such as 30 minutes, in order to improve the accuracy of the adjustment, the patient's physical condition can be evaluated every 1 minute within the 30 minutes, so as to adjust the therapeutic gas concentration in time according to the patient's physical condition and obtain the adjusted therapeutic gas concentration.

[0044] Step S106: If the adjusted therapeutic gas concentration is less than the first concentration threshold, and the output duration of the adjusted therapeutic gas concentration reaches a preset duration, the medical device is controlled to stop offline in a preset manner.

[0045] The above-mentioned first concentration threshold can be set according to actual needs, and is usually a smaller concentration value. For example, the range of the first concentration threshold can be 0.1ppm to 10ppm, and the preferred range is 0.1ppm to 5ppm. More preferably, the first concentration threshold is 1ppm. The above-mentioned preset time length can be set according to actual needs. For example, the range of the preset time length can be 1 minute to 10 hours, and preferably, it can be 1 hour to 4 hours. In actual implementation, when it is monitored that the adjusted therapeutic gas concentration is less than the first concentration threshold, and the duration reaches the preset duration, the medical device can be controlled to stop the offline action in a preset manner. For example, the medical device can be controlled to stop continuing to adjust the therapeutic gas concentration, or the medical device can be controlled to stop outputting therapeutic gas, etc.

[0046] The offline control method of the above-mentioned medical device obtains the current therapeutic gas concentration and the preset time period output by the medical device; based on the preset time period, the current therapeutic gas concentration is adjusted to obtain the adjusted therapeutic gas concentration; if the adjusted therapeutic gas concentration is less than the first concentration threshold, and the output duration of the adjusted therapeutic gas concentration reaches the preset duration, the medical device is controlled to stop offline in a preset manner. This method can automatically adjust the current therapeutic gas concentration based on the preset time period, thereby automatically controlling the offline progress, reducing labor costs, and improving offline efficiency and the accuracy of offline control.

[0047] The embodiment of the present invention further provides another offline control method for medical equipment, which is implemented on the basis of the method in the above embodiment, and comprises the following steps:

[0048] Step 1, obtaining the current therapeutic gas concentration and preset time period output by the medical device;

[0049] Step 2: Obtaining the patient's physical index information;

[0050] The above-mentioned patient physical indicator information can be used to indicate the patient's physical health status. For example, the patient's physical indicator information may include: the patient's inhaled oxygen concentration, blood oxygen saturation, blood oxygen partial pressure, airway pressure, mean airway pressure, etc.; in actual implementation, in order to realize the intelligent offline of medical equipment, it is usually necessary to obtain the patient's physical indicator information.

[0051] Step 3, for each first time period within the current preset time period, calculate the current calculated value of the patient's physical index information within the current first time period; wherein the first time period is less than or equal to the preset time period;

[0052] The above-mentioned first time period is usually a short period of time. If the preset time period is shorter, the first time period can be the same as the preset time period, that is, only one first time period is included in the preset time period; if the preset time period is longer, the first time period is usually shorter than the preset time period, that is, multiple first time periods are included in the preset time period. For example, the preset time period is 10 minutes, and the first time period is 10 seconds. Then, within the 10 minutes of the current preset time period, the current calculated value of the patient's physical index information within the current 10 seconds is calculated every 10 seconds; in actual implementation, the patient's physical index information can be obtained according to the preset collection frequency, for example, it can be real-time collection or collection once per second, etc., then multiple patient physical index information can be collected in the current first time period, and based on these patient physical index information, the current calculated value corresponding to the current first time period can be calculated according to the preset calculation method, and the current calculated value is usually a specific value.

[0053] In one embodiment, the patient's physical index information includes: the patient's blood oxygen saturation and inspired oxygen concentration; blood oxygen saturation is the percentage of the volume of oxygenated hemoglobin bound by oxygen in the blood to the total volume of hemoglobin that can be bound, that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of the respiratory cycle; inspired oxygen concentration refers to the concentration of inspired oxygen; then step three can be implemented by following steps 30 to 31:

[0054] Step 30, for each first time period within the current preset time period, calculating a first average value of a plurality of blood oxygen saturations of the patient within the current first time period, and a second average value of a plurality of inspired oxygen concentrations;

[0055] For example, taking the first time period as 1 minute, the patient's physical indicator information is collected once every second. In the current first time period, 60 blood oxygen saturation data and 60 inhaled oxygen concentration data can be collected, and the first average value of the 60 blood oxygen saturations and the second average value of the 60 inhaled oxygen concentrations can be calculated.

[0056] Step 31, calculate the ratio of the first average value to the second average value to obtain a current calculated value.

[0057] For example, taking the first average value of multiple blood oxygen saturations as SpO2 and the second average value of multiple inspired oxygen concentrations as FiO2 as an example, the current calculated value can be calculated according to the following formula:

[0058] Sa / F=SpO2 / FiO2.

[0059] In another embodiment, the patient's physical index information includes: the patient's blood oxygen saturation, airway pressure and inspired oxygen concentration; airway pressure can be understood as the airway pressure generated or measured by the patient's spontaneous breathing and the ventilator's air supply when the ventilator is used for mechanical ventilation. Then step three can be implemented by following steps 32 to 34:

[0060] Step 32, for each first time period within the current preset time period, calculating a third average value of multiple airway pressures, a fourth average value of multiple inspired oxygen concentrations, and a fifth average value of multiple blood oxygen saturations of the patient within the current first time period;

[0061] For example, still taking the first time period as 1 minute, the patient's physical index information is collected once per second. Then, in the current first time period, 60 airway pressure data, 60 blood oxygen saturation data, and 60 inspired oxygen concentration data can be collected, and the third average value of the 60 airway pressures, the fourth average value of the 60 inspired oxygen concentrations, and the fifth average value of the 60 blood oxygen saturations can be calculated.

[0062] Step 33, calculating the product of the third average value, the fourth average value and the preset value to obtain a first product result;

[0063] Step 34, calculating the ratio of the first product result to the fifth average value to obtain a current calculated value.

[0064] The above preset value can be set according to actual needs, for example, the preset value can be 100, etc. For the convenience of explanation, taking the third average value of multiple airway pressures as Pmean, the fourth average value of multiple inspired oxygen concentrations as FiO2, and the fifth average value of multiple blood oxygen saturations as SpO2 as examples, the current calculated value can be calculated according to the following formula:

[0065] OSI=(Pmean*FiO2*100) / SpO2.

[0066] In practical applications, any one of the above methods can be selected to calculate the current calculation value, or the current calculation values ​​obtained by the two calculation methods can be combined to determine the final current calculation value. For example, the current calculation value obtained by the two calculation methods that is more different from the first calculation value of the previous preset time period can be used as the final current calculation value.

[0067] Step 4, determining the concentration adjustment amount of the treatment gas according to the current calculated value and the first calculated value of the patient's physical index information obtained in advance within the last preset time period;

[0068] The fourth step can be implemented by following steps 40 to 45:

[0069] Step 40, calculating a first difference between the current calculated value and a first calculated value of the patient's physical indicator information obtained in advance within a previous preset time period;

[0070] If the preset time period includes multiple first time periods, multiple calculation values ​​can be calculated in the last preset time period, and each calculation value can be calculated in the same preset calculation method as the current calculation value. The above-mentioned first calculation value can be any calculation value in the last preset time period, preferably, it can be the calculation value corresponding to the last first time period in the last preset time period; for example, the preset time period is 30 minutes, and the therapeutic gas output concentration is 50ppm from 0 to 30 minutes; after 30 minutes, it is lowered to 45ppm, and the calculation value is calculated every 10 seconds. Then the first calculation value here can be a calculation value within 0 to 30 minutes, considering that the patient's physical indicators change relatively slowly. When the concentration of the therapeutic gas changes, the later data can better reflect the patient's physical adaptation under the current therapeutic gas concentration. Therefore, preferably, the calculation value from 29 minutes 50 seconds to 30 minutes in the last preset time period can be used as the first calculation value. From 30 to 60 minutes, the current calculation value calculated every 10 seconds is compared with the first calculation value corresponding to 29 minutes 50 seconds to 30 minutes.

[0071] According to the current calculated value and the first calculated value, the stability of the patient's physical condition can be evaluated. For example, if the current calculated value is significantly different from the first calculated value, it means that the patient's physical condition is more unstable. The concentration adjustment amount of the therapeutic gas can be determined according to the current calculated value and the first calculated value. The concentration adjustment amount can be to increase, decrease or maintain the current therapeutic gas concentration. Usually, the therapeutic gas concentration in the same first time period remains unchanged, and the therapeutic gas concentration in different first time periods may be the same or different; it should be noted that if the current preset time period is the first preset time period, that is, there is no previous preset time period, in this case, the medical device can be controlled to output the therapeutic gas according to the preset therapeutic gas concentration. The preset therapeutic gas concentration can be the therapeutic gas concentration set by the user, or the default initial therapeutic gas concentration of the medical device, etc.

[0072] Step 41, calculating the ratio of the first difference value to the first calculated value to obtain a variation range;

[0073] In actual implementation, the change between the current calculated value and the first calculated value corresponding to the previous preset time period can be determined by calculating the above-mentioned first difference, and then the ratio of the first difference to the first calculated value can be calculated to obtain the change range, which can be expressed as a percentage, such as 4%, 8%, etc.

[0074] Step 42, if the change range is within the first interval, taking the next first time period as the new current first time period, and repeatedly executing the step of calculating the current calculated value of the patient's physical index information in the current first time period until the last first time period in the current preset time period, and determining that the concentration adjustment amount of the treatment gas is the first preset value;

[0075] Step 43, if the variation range is within the second interval, determining the concentration adjustment amount of the therapeutic gas to be a second preset value;

[0076] Step 44, if the change range is within the third interval, determining the concentration adjustment amount of the therapeutic gas to be a third preset value;

[0077] Step 45, if the change range is within the fourth interval, determine the concentration adjustment amount of the therapeutic gas to be the fourth preset value; wherein the second interval is greater than the first interval and less than the third interval, and the fourth interval is greater than the third interval; the third preset value is greater than the second preset value and less than the fourth preset value.

[0078] The first interval, the second interval, the third interval and the fourth interval can be set according to actual needs, and the ranges of these four intervals increase in sequence, for example, the first interval is ±5%, the second interval is ±5% to ±10%, the third interval is ±10% to ±20%, and the fourth interval is greater than ±20%. The first preset value, the second preset value, the third preset value and the fourth preset value can be set according to actual needs. For example, the first preset value can be the treatment gas concentration C in the previous time period. i-1 Half of the first preset value a=C i-1 / 2; or, the first preset value is a fixed value, preferably in the range of 0.1ppm to 5ppm, more preferably 1ppm, which can be set according to actual needs and is not limited here. The second preset value, the third preset value and the fourth preset value can be fixed values, preferably in the range of 0.1ppm to 5ppm, and usually these three preset values ​​increase in sequence, which can be set according to actual needs and are not limited here.

[0079] In actual implementation, when the above-mentioned change range is within the first interval (such as within ±5%), it can be considered that the patient's physical condition is relatively stable. At this time, it can be determined whether to lower the current treatment gas concentration to the first preset value according to the situation of the first time period within the current preset time period; for example, the preset time period is 30 minutes, and from 0 to 30 minutes, the treatment gas output concentration is 50ppm, and after 30 minutes, it is adjusted down to 45ppm; if 10 seconds after 30 minutes, the monitoring finds that the current calculated value of SpO2 / FiO2 has changed compared with the first calculated value of the previous preset time period, If the change range is not large, that is, it belongs to the first interval, no downward adjustment will be made first, but wait until 60 minutes. If it is monitored that the current calculated value calculated every 10 seconds has not changed much, that is, the change range corresponding to each current calculated value calculated belongs to the first interval, then it can be adjusted down to 40ppm after 60 minutes; if 10 seconds after 30 minutes, it is monitored that the current calculated value of SpO2 / FiO2 has a large change compared with the first calculated value of the previous preset time period, the concentration of the therapeutic gas can be adjusted back immediately instead of waiting until 60 minutes.

[0080] When the above-mentioned change range is within the second interval (the second interval is larger than the first interval, for example, between ±5% and ±10%), in order to further improve the accuracy of control, the current therapeutic gas concentration may not be adjusted temporarily, and a first time period may be observed. If the change range is still within the second interval, the current therapeutic gas concentration may be increased by the second preset value. When the above-mentioned change range is within the third interval (the third interval is larger than the second interval, for example, between ±10% and ±20%), the current therapeutic gas concentration may be increased by the third preset value. When the above-mentioned change range is within the fourth interval (the fourth interval is larger than the third interval, for example, greater than ±20%), the current therapeutic gas concentration may be increased by the fourth preset value. It can be understood that generally, the larger the change range (whether it is larger or smaller), the more unstable the patient's physical condition is. In this case, the therapeutic gas concentration needs to be increased, and the larger the change range, the larger the range that needs to be increased.

[0081] Step five, adjusting the current therapeutic gas concentration according to the concentration adjustment amount to obtain an adjusted therapeutic gas concentration, so that the medical device outputs the therapeutic gas according to the adjusted therapeutic gas concentration in the next first time period.

[0082] In actual implementation, after the concentration adjustment amount is determined, the current therapeutic gas concentration can be adjusted according to the concentration adjustment amount to obtain the adjusted therapeutic gas concentration; for example, if the concentration adjustment amount is 3ppm, the current therapeutic gas concentration can be adjusted up by 3ppm, and if the concentration adjustment amount is -1ppm, the current therapeutic gas concentration can be adjusted down by 1ppm; then in the next first time period, the therapeutic gas can be output according to the adjusted therapeutic gas concentration. The next first time period is taken as the new current first time period, and the above steps are repeated to automatically determine the therapeutic gas concentration required for each subsequent first time period.

[0083] The step five can be implemented by following the steps 50 to 52:

[0084] Step 50, sending a first prompt message to the user to prompt the user to confirm the concentration adjustment amount;

[0085] Step 51, if a confirmation indication of the concentration adjustment amount is received from the user, the current therapeutic gas concentration is adjusted according to the concentration adjustment amount to obtain an adjusted therapeutic gas concentration; so that the medical device outputs the therapeutic gas according to the adjusted therapeutic gas concentration in the next first time period;

[0086] In this embodiment, you can choose the function without manual intervention, and then execute the full closed-loop offline process. You can also choose the manual intervention function. If you choose to require manual intervention, a semi-closed-loop offline process will be executed. The user can switch the semi-closed-loop process to a full closed-loop process during the offline stage. The full closed-loop process means that the concentration is adjusted automatically by the system. When the treatment gas concentration needs to be adjusted during the offline stage, it will be automatically adjusted according to the logic without manual confirmation, but manual intervention can be made at any time. The semi-closed-loop process means that the action of adjusting the concentration requires manual intervention or confirmation.

[0087] In actual implementation, after the concentration adjustment amount is determined, when the current therapeutic gas concentration needs to be adjusted according to the concentration adjustment amount, the user can be prompted to perform the operation. Specifically, the concentration adjustment amount can be displayed to the user, and the user can be prompted to confirm the concentration adjustment amount. If the user clicks the confirmation control, the above confirmation indication can be received. At this time, the current therapeutic gas concentration can be directly adjusted according to the concentration adjustment amount to obtain the adjusted therapeutic gas concentration.

[0088] Step 52: If a modification instruction for the concentration adjustment amount is received from the user, the concentration adjustment amount is modified according to the modification instruction, and the current therapeutic gas concentration is adjusted according to the modified concentration adjustment amount to obtain the adjusted therapeutic gas concentration, so that the medical device outputs therapeutic gas according to the adjusted therapeutic gas concentration in the next first time period.

[0089] In actual implementation, after the concentration adjustment amount is displayed to the user, if the user thinks that the concentration adjustment amount is inappropriate, the user can also modify the concentration adjustment amount. At this time, the user's modification instruction for the concentration adjustment amount can be received, and the above-generated concentration adjustment amount can be modified according to the modification instruction. The current treatment gas concentration can be adjusted according to the modified concentration adjustment amount to obtain the adjusted treatment gas concentration.

[0090] In another embodiment, the present solution may also support users to independently set the concentration adjustment amount, that is, the concentration adjustment amount is not displayed to the user, but the user independently increases, maintains or decreases the current treatment gas concentration according to actual needs.

[0091] Step six, if the adjusted therapeutic gas concentration is less than the first concentration threshold, and the output duration of the adjusted therapeutic gas concentration reaches a preset duration, control the medical device to continuously output the therapeutic gas at the adjusted therapeutic gas concentration; or, control the medical device to stop outputting the therapeutic gas; or, send a second prompt message to the user to prompt the user to operate the medical device to stop outputting the therapeutic gas.

[0092] In actual implementation, when the adjusted therapeutic gas concentration is less than the first concentration threshold and the duration reaches a preset duration, the medical device can be controlled to stop the offline action in a preset manner. The offline stop action can be to control the medical device to continuously output the therapeutic gas at the adjusted therapeutic gas concentration and no longer automatically adjust the therapeutic gas concentration; or, the offline stop action can be to control the medical device to stop outputting the therapeutic gas; or, the offline stop action can be to prompt the user to perform an operation to stop outputting the therapeutic gas. In specific applications, the appropriate offline stop action can be selected according to the actual application scenario, so as to meet a variety of different application requirements.

[0093] Step 7: if an offline action pause indication is received, obtain an offline action pause time period;

[0094] Step eight, during the offline action suspension time period, control the medical device to output the therapeutic gas according to the first therapeutic gas concentration; wherein the first therapeutic gas concentration is the therapeutic gas concentration before reaching the offline action suspension time period.

[0095] In actual applications, it is sometimes necessary to control the medical equipment to stop offline action, that is, to stop the action of automatically adjusting the treatment gas concentration. For example, when human resources and medical resources are limited at night, the user can issue the above-mentioned offline action pause instruction through operation. The offline action pause instruction usually carries an offline action pause time period. For example, the offline action pause time period can be 0:00-6:00. When the offline action pause time period is reached, the night pause function can be turned on. During the offline action pause time period, the offline stage action will be stopped, that is, the treatment gas concentration will remain unchanged, and the treatment gas concentration will no longer be adjusted according to the preset time period to reduce the risk of emergencies under limited resources.

[0096] Step nine, obtaining the total current treatment time of the treatment gas output by the medical device, and obtaining the standard usage time of the specified consumables in the medical device;

[0097] Step 10, determining the remaining usage time of the designated consumables according to the standard usage time and the current total treatment time;

[0098] The above-mentioned current total treatment time can be understood as the duration of treatment using the therapeutic gas output by the medical device up to the current time; the above-mentioned designated consumables can be consumables in the medical device that affect the quality of the therapeutic gas; the above-mentioned standard usage time can be understood as the service life of the designated consumables; for example, taking NO therapeutic gas as an example, the designated consumable is a filter. NO may be oxidized to NO2 during transmission. Therefore, a filter is required to remove NO2. During the use of the filter, the filter element material used to remove NO2 is continuously reacted and consumed. Therefore, the usage time of the filter is limited. After exceeding the standard usage time, the removal effect of NO2 may be reduced, which is not conducive to patient inhalation. In actual implementation, the difference between the obtained standard usage time and the current total treatment time can be calculated to obtain the remaining usage time of the designated consumable.

[0099] Step 11, calculating the offline prediction time consumption according to the current treatment gas concentration and the preset time period;

[0100] In actual implementation, the theoretical offline phase duration can be estimated based on the current therapeutic gas concentration and the preset time period, that is, the above-mentioned offline predicted time. For example, the current therapeutic gas concentration is 10ppm, the preset time period is 10 minutes, and each preset time period is reduced by 1ppm. It is estimated that the offline process will be completed after 100 minutes, that is, the offline predicted time is 100 minutes.

[0101] Step 12: Compare the remaining usage time with the offline predicted time to obtain a comparison result, and determine whether the life of the specified consumable is sufficient according to the comparison result.

[0102] The above-mentioned remaining usage time can be compared with the offline predicted time to obtain a comparison result, which may be that the remaining usage time is greater than, less than or equal to the offline predicted time. The comparison result can be displayed to the user to prompt the user in time; if the remaining usage time is greater than or equal to the offline predicted time, it can be considered that the life of the specified consumable is sufficient for this treatment process; if the remaining usage time is less than the offline predicted time, it can be considered that the life of the specified consumable is insufficient to support the current treatment process.

[0104] In this embodiment, the medical device may include: a therapeutic gas source, a therapeutic gas output path, an information acquisition module, and a concentration control module; wherein the therapeutic gas source is used to generate therapeutic gas; the therapeutic gas output path is connected to the inhalation branch of the ventilation device and is used to output the therapeutic gas; the information acquisition module is used to obtain relevant data information, and the data information may include: current therapeutic gas concentration, current total treatment time, blood oxygen saturation, blood oxygen partial pressure, inhaled oxygen concentration, preset time period, etc.; the concentration control module is used to step-by-step control the increase / decrease / maintenance of the output therapeutic gas concentration according to demand, thereby completing the offline action.

[0107] Step fourteen, displaying the sixth information area, the seventh information area, and the eighth information area through the display; wherein the sixth information area is used to set a preset time period; the seventh information area is used to switch interfaces; the eighth information area is used to set whether manual confirmation is required; the sixth information area and the eighth information area are displayed on the same second display interface or different second display interfaces.

[0108] The above-mentioned second display interface can be an offline setting interactive interface, and the above-mentioned sixth information area and eighth information area can be located in the same second display interface at the same time, or can be located in different second display interfaces respectively; if the sixth information area and the eighth information area are located in the same second display interface at the same time, the seventh information area will be displayed in the second display interface; if the sixth information area and the eighth information area are located in multiple different second display interfaces respectively, the seventh information area will be displayed in each second display interface.

[0109] like Figure 6, in which the sixth area (corresponding to the sixth information area) is displayed separately on a second display interface, and the seventh area (corresponding to the seventh information area) is displayed on the right side of the figure. Figure 7 Another schematic diagram of the second display interface is shown, in which the sixth area and the eighth area (corresponding to the eighth information area) are located on the same second display interface, and the seventh area is displayed on the right side of the figure. A sixteenth area can also be displayed on the second display interface for selecting and / or setting the concentration adjustment amount.

[0110] The first information area, the second information area, the third information area, the fourth information area, the fifth information area, the sixth information area, and the seventh information area are operable areas, and interactive actions can be performed in the corresponding areas by touching or pressing keys. Interactive actions include inputting information, confirming information, etc.

[0111] Step fifteen, displaying the ninth information area, the tenth information area and the eleventh information area through the display; wherein the ninth information area is used to set whether to start the offline action pause function; the tenth information area is used to set the offline action pause time period; the eleventh information area is used for interface switching; the ninth information area and the tenth information area are displayed on the same third display interface or different third display interfaces.

[0112] The above-mentioned third display interface can be a night pause interactive interface. The above-mentioned ninth information area and tenth information area can be located in the same third display interface at the same time, or can be located in different third display interfaces respectively. If the ninth information area and the tenth information area are located in the same third display interface at the same time, the eleventh information area will be displayed in the third display interface; if the ninth information area and the tenth information area are located in different third display interfaces respectively, the eleventh information area will be displayed in each third display interface.

[0113] like Figure 8 A schematic diagram of a third display interface is shown, in which the ninth area (corresponding to the above-mentioned ninth information area) and the tenth area (corresponding to the above-mentioned tenth information area) are displayed on a third display interface, and the eleventh area (corresponding to the above-mentioned eleventh information area) is displayed on the right side of the figure.

[0114] Step sixteen, displaying the twelfth information area through the display; wherein the twelfth information area is used to display the offline prediction time; the twelfth information area is displayed on the second display interface or the third display interface.

[0115] For example, if the second display interface is an offline setting interactive interface and the third display interface is a nighttime pause interactive interface, the twelfth information area may be displayed in the offline setting interactive interface or the nighttime pause interactive interface. Fig. 9A schematic diagram of another third display interface is shown, in which the twelfth area (corresponding to the above-mentioned twelfth information area) is displayed in the same third display interface with the ninth area, the tenth area and the eleventh area, and the twelfth area is displayed in the upper right corner of the third display interface.

[0116] Step seventeen, displaying the thirteenth information area through the display; wherein the thirteenth information area is used to set whether to start offline.

[0117] The above-mentioned thirteenth information area can be displayed on the offline startup confirmation interface, such as Fig.10 A schematic diagram of an offline start confirmation interface is shown, in which "YES" and "NO" controls are displayed in the thirteenth area (corresponding to the above-mentioned thirteenth information area). When the user triggers the "YES" control, it indicates that the intelligent offline is started. The automatic offline process can be executed according to the aforementioned embodiment, and the "NO" control is triggered, indicating that the intelligent offline is not started.

[0118] Step eighteen, displaying the fourteenth information area and the fifteenth information area on the display; wherein the fourteenth information area is used to display information on changes in the concentration of the therapeutic gas over time during the offline process; and the fifteenth information area is used to display the duration of offline operation.

[0119] The fourteenth information area and the fifteenth information area can be displayed on the offline information summary interface, such as Fig.11 A schematic diagram of an offline information summary interface is shown, in which the fourteenth area (corresponding to the above-mentioned fourteenth information area) displays information on changes in therapeutic gas concentration over time during the offline process, and the fifteenth area (corresponding to the above-mentioned fifteenth information area) displays the offline duration.

[0120] The offline control method of the above-mentioned medical equipment, based on the current treatment status data (such as the set nitric oxide concentration, the current total treatment time) and real-time monitoring data (such as PaO2, FiO2, etc.), can accurately adjust the concentration of the therapeutic gas to reduce it at an appropriate speed until the inhalation of the therapeutic gas treatment is stopped, thereby avoiding the occurrence of the "rebound phenomenon".

[0121] This method can monitor the patient's physical index information in real time during the entire offline process, and automatically determine the concentration adjustment of the therapeutic gas based on the acquired patient's physical index information, so that the medical device can output the therapeutic gas according to the adjusted therapeutic gas concentration in the next first time period, thereby automatically controlling the offline progress, reducing labor costs, and improving offline efficiency and offline control accuracy. During the entire offline process, clinical users can set whether manual confirmation is required before adjusting the therapeutic gas, and whether the decrease in the therapeutic gas concentration needs to be automatically suspended at night based on actual manpower conditions.

[0122] This method can realize a semi-closed loop offline process or a fully closed loop offline process, and follows the OODA concept (O: Observe, Observe; O: Orient, Adjust; D: Decide, Decision; A: Act, Action), which improves efficiency while ensuring safety. The offline function is no longer a simple fixed time and fixed speed to reduce the concentration of therapeutic gas. There is no need to increase the relevant settings of physical indicator information, clinical workers' manpower, and medical resources. The final generated offline plan is more in line with the actual situation and more intelligent. While efficiently utilizing resources, it also improves the safety of offline and the ability to respond to emergencies.

[0123] This approach can also provide more offline strategies: a fully closed-loop OODA process strategy that relies entirely on indicator detection and is controlled by the system; and a semi-closed-loop OODA process strategy that relies on auxiliary indicator detection and is controlled by both the system and manual intervention. The former is completely automatic throughout the offline process, and the decision-making process relies on monitoring indicators such as OI / OSI / PF ratio / SpO2, which is more efficient. The latter means that the decision-making process requires clinical users to make a judgment before entering the next stage. Although people are in the loop, it is relatively safe, but the execution efficiency is limited by manpower. This solution combines the two on the basis of the fully closed-loop OODA process, and introduces a "people in the loop" decision-making mechanism. Users can intervene in the OODA process at any time and make adjustments, which not only ensures efficiency but also increases safety.

[0124] In the fully closed-loop process, during the weaning process, when reducing the therapeutic gas concentration, it is necessary to observe the monitoring indicators of oxygenation (OI index or P / F or SpO2) to determine whether the patient's endogenous therapeutic gas has been sufficiently secreted. If the body meets the standard, the therapeutic gas concentration is reduced. If the body has not yet reached the standard, the therapeutic gas concentration needs to be increased to the original therapeutic concentration. Therefore, the whole process actually follows the OODA concept, that is, observation-adjustment-decision-action, over and over again until the patient is offline. The offline control method currently on the market is only a unilateral reduction in the therapeutic gas concentration, and there is no observation-decision-making process at all. There is a very large clinical risk. This solution realizes the complete OODA process for the first time.

[0125] In the process of reducing the concentration of therapeutic gas, due to the upper limit of human workload, in related technologies, each observation cycle of the treatment gas concentration reduction is as long as 4-6 hours, which means that an OODA process takes several hours, and only 5-10 OODA processes can be executed during the entire offline process, which is very inefficient. This solution shortens the OODA process to 5-10 minutes through computer automatic control, but greatly increases the number of cycles of the OODA process, and reduces offline time and clinical costs through a rapid observation-adjustment-decision-action process.

[0126] In the existing offline process, for convenience, the step-down treatment follows the "half-reduction principle", that is, the treatment gas concentration is reduced to half of the original concentration each time; this principle is simple to implement, but the gradient of the treatment gas concentration is too large each time, and the body may not be able to adapt quickly, so the observation period is very long. This scheme adopts the principle of rapid continuous decline, that is, the treatment gas concentration can be reduced by a small dose (such as 1ppm) each time, but the OODA frequency is increased, and the purpose of rapid and safe offline is achieved through more frequent small-dose treatment gas concentration adjustments (which can be increased or decreased).

[0127] The embodiment of the present invention provides an offline control device for medical equipment, such as Fig.12 As shown, the device includes: an acquisition module 120, used to obtain the current therapeutic gas concentration and a preset time period output by the medical device; an adjustment module 121, used to adjust the current therapeutic gas concentration based on the preset time period to obtain an adjusted therapeutic gas concentration; a control module 122, used to control the medical device to stop offline in a preset manner if the adjusted therapeutic gas concentration is less than a first concentration threshold and the output duration of the adjusted therapeutic gas concentration reaches a preset duration.
