Description

Technical Field

[0001] This application relates to the field of medical technology, and in particular, to a control method, device, electronic device, and storage medium for a thoracic drainage device. Background Art

[0002] Thoracic drainage is an important medical procedure used to drain gas, liquid, blood, etc. from the thoracic cavity to restore the normal pressure and physiological function in the thoracic cavity. Clinically, it is necessary to monitor the drainage volume and air leakage volume of the patient through a thoracic drainage device, and determine the extubation time according to whether the monitoring data meets the extubation criteria. The current extubation criteria recommended by the thoracic surgery extubation guidelines are that the drainage volume is less than 500 ml in 24 hours, and the air leakage rate is less than 40 ml / min for 8 consecutive hours. The thoracic drainage device will start timing from the beginning of drainage until the above two conditions are met, and then stop drainage and extubation when the timing ends.

[0003] However, in the actual treatment process, medical staff cannot always take care of the patient, and the patient will not always remain quiet. If the patient gets out of bed and moves during the treatment, causing the device to be in a moving state and the liquid level in the drainage bottle to fluctuate up and down, or if the patient unconsciously touches the device, causing the drainage pipe to be blocked or the drainage bottle to fall off, these will all interfere with the monitoring of the drainage volume and air leakage rate, making the monitored data unable to reflect the normal treatment situation, thus interfering with the determination of the stop drainage and extubation time, resulting in an early or late determination time, increasing the treatment risk of the patient and the unnecessary workload of the medical staff.

[0004] Therefore, the current thoracic drainage device has the technical problem of inaccurate determination of the stop drainage time and needs to be improved. Summary of the Invention

[0005] Embodiments of this application provide a control method, device, electronic device, and storage medium for a thoracic drainage device to alleviate the technical problem of inaccurate determination of the stop drainage time by the current thoracic drainage device.

The thoracic drainage device includes a first timer, a second timer, and a drainage device. The drainage device includes a drainage tube and a drainage bottle. The drainage tube is connected to the chest cavity of the target patient. The drainage bottle includes an NFC tag. The device includes:

[0043] The acquisition module is used to obtain the tilt angle of the thoracic drainage device in real time, obtain the pressure difference between the thoracic pressure and the drainage bottle pressure of the target patient in real time, and obtain the NFC tag recognition result of the drainage bottle in real time.

[0044] The third judgment module is used to judge whether the drainage pause condition is satisfied at any moment, and the drainage pause condition is that the tilt angle is greater than the preset angle, and / or the pressure difference is greater than the threshold, and / or the NFC tag recognition result is that the tag is incorrect.

[0045] A fourth control module, configured to, if the result is negative, control the first timer to continue timing and control the drainage device to continue collecting the drainage volume of the target patient; if the result is positive, control the first timer to pause timing, control the drainage device to pause collecting the drainage volume of the target patient, and after pausing the timing, continue to perform the operation of judging whether the drainage pause condition is satisfied, the operation of pausing the timing and pausing the collection when the judgment result is positive, until the judgment result is negative, control the first timer to continue timing from the first pause moment, and control the drainage device to continue collecting the drainage volume of the target patient from the first pause moment;

[0050] The embodiment of the present application provides a computer-readable storage medium, which stores multiple instructions, and the instructions are suitable for being loaded by a processor to execute the steps in the control method of the thoracic drainage device described above.

[0051] Beneficial effects: The present application provides a control method, device, electronic device, and storage medium for a thoracic drainage device. The method uses a first timer to time the drainage volume and a second timer to time the air leakage rate. If the current drainage volume is not less than the reference drainage volume during the process, the first timer will be cleared, and the timing and collection of the drainage volume will be restarted. If not, the timing and collection will continue. If the current air leakage rate is not less than the reference air leakage rate during the process, the second timer will be cleared, and the timing and collection of the air leakage rate will be restarted. If not, the timing and collection will continue. In addition, at any moment, it will be determined whether the drainage pause condition is met. If so, the first timer will be paused, and the paused time will not be included in the cumulative duration, and the drainage volume will not be collected either. Subsequently, if not, the timing and collection will continue. At the same time, it will also be determined whether the air leakage pause condition is met. If so, the second timer will be paused, and the paused time will not be included in the cumulative duration, and the air leakage rate will not be collected either. Subsequently, if not, the timing and collection will continue. Finally, when the cumulative durations of the first timer and the second timer both meet the conditions, it is determined that it is time to stop the drainage, and the drainage device can be controlled to stop the drainage. Due to the setting of a reasonable timing clearing and timing pause mechanism, the timing is only determined based on the data fluctuations under normal conditions of the patient, excluding the interference of abnormal factors such as device tilt, drainage tube blockage, and drainage bottle detachment. Therefore, the determination of the timing to stop the drainage can be made more accurately. Description of the Drawings

[0059] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0060] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the application scenario of the control method of the thoracic drainage device provided by the embodiment of the present application. This scenario includes a thoracic drainage device. The thoracic drainage device includes a drainage device, and the drainage device includes a drainage tube, a drainage bottle, and other software and hardware units related to drainage. When a patient needs treatment, the drainage device drains the patient's thoracic cavity through the drainage tube, and the drainage fluid will enter the drainage bottle. When the patient does not need treatment, the drainage device needs to stop drainage. The thoracic drainage device includes a first pressure sensor, a second pressure sensor, an inclination angle sensor, an NFC identification device, a first timer, and a second timer, etc. By combining the above-mentioned hardware with an embedded algorithm unit, the timing of stopping drainage can be accurately determined. In the following embodiments, the process of how to determine will be described in detail.

[0061] Please refer to Figure 2 , Figure 2 which is the first flowchart of the control method of the thoracic drainage device provided by the embodiment of the present application. The method specifically includes:

[0062] S1: Control the first timer to start timing from the first initial moment, and control the drainage device to start collecting the drainage volume of the target patient in real time from the first initial moment; control the second timer to start timing from the second initial moment, and control the drainage device to start collecting the air leakage rate of the target patient in real time from the second initial moment.

[0063] After starting treatment, the first timer starts timing from the first initial moment. At the same time, the drainage device can start collecting the drainage volume of the target patient in real time from the first moment. Specifically, the liquid level of the drainage bottle is identified by a liquid level sensor provided on the drainage bottle to obtain the drainage volume. At the first initial moment, the liquid level in the drainage bottle is preferably 0. Subsequently, as the drainage fluid increases, the liquid level will gradually rise, and the value of the identified drainage volume will also increase continuously. The unit of the drainage volume is ml. The second timer starts timing from the second initial moment. At the same time, the drainage device starts collecting the air leakage rate of the target patient in real time from the second initial moment. The air leakage rate can be calculated based on a preset algorithm after collecting data such as thoracic cavity pressure and the duty cycle of the pressure negative pump. The unit of the air leakage rate is ml / min.

[0064] S2: When the accumulated duration of the first timer is less than the first duration, determine whether the drainage zeroing condition is satisfied at any moment. The drainage zeroing condition is that the current drainage volume is not less than the reference drainage volume.

[0065] The accumulated duration of the first timer is continuously increasing. Before the accumulated duration reaches the first duration, it is necessary to determine whether the drainage zeroing condition is satisfied at any moment. This condition is that the current drainage volume is not less than the reference drainage volume. The extubation indicators defined in the extubation guidelines include that the drainage volume in 24 hours is less than 500 ml, and the peak air leakage rate in 8 consecutive hours is less than 40 ml / min. Based on this, the first duration is set to 24 hours, and the reference drainage volume is set to 500 ml.

[0066] S3: If so, reset the first timer, control the first timer to restart timing from the first reset moment, and control the drainage device to restart collecting the drainage volume of the target patient from the first reset moment; if not, control the first timer to continue timing, and control the drainage device to continue collecting the drainage volume of the target patient.

[0067] If the judgment result is yes, it means that it has not reached 24 hours but the current drainage volume has reached or exceeded 500 ml. Continuing to time cannot meet the extubation indicators. At this time, it is necessary to reset the first timer, use the current moment as the first reset moment, control the first timer to restart timing from this moment, and at the same time the drainage device will also start to restart collecting the drainage volume of the target patient from this moment. It should be noted that since there is previously collected drainage fluid in the drainage bottle, when restarting to collect the drainage volume, the calculated value is the increment starting from this moment.

[0068] If the judgment result is no, it means that the current drainage volume has not reached 500 ml within 24 hours, which is a normal situation. At this time, directly control the first timer to continue timing, and control the drainage device to continue collecting the drainage volume of the target patient.

[0069] S4: Determine whether the air leakage zeroing condition is satisfied at any moment. The air leakage zeroing condition is that the current air leakage rate is not less than the reference air leakage rate.

[0070] At any moment, it is also necessary to determine whether the air leakage zeroing condition is satisfied. This condition is that the current air leakage rate is not less than the reference air leakage rate. The extubation indicators defined in the extubation guidelines include that the drainage volume in 24 hours is less than 500 ml, and the peak air leakage rate in 8 consecutive hours is less than 40 ml / min. Based on this, the reference air leakage rate is set to 40 ml / min.

[0071] S5: If yes, clear the second timer, control the second timer to restart timing from the second clearing moment, and control the drainage device to restart collecting the air leakage rate of the target patient from the second clearing moment; if no, control the second timer to continue timing and control the drainage device to continue collecting the air leakage rate of the target patient.

[0072] If the judgment result is yes, it means that the current air leakage rate has reached or exceeded 40 ml / min, and continuing to time cannot meet the extubation index. At this time, the second timer needs to be cleared, and the current moment is used as the second clearing moment. Control the second timer to restart timing from this moment. At the same time, the drainage device will also start to restart collecting the air leakage rate of the target patient from this moment.

[0073] If the judgment result is no, it means that the current air leakage rate has not reached 40 ml / min, which is a normal situation. At this time, directly control the second timer to continue timing and control the drainage device to continue collecting the air leakage rate of the target patient.

[0074] S6: Real-time obtain the tilt angle of the thoracic drainage device, real-time obtain the pressure difference between the thoracic pressure and the drainage bottle pressure of the target patient, and real-time obtain the NFC tag recognition result of the drainage bottle.

[0075] The main factor that easily causes abnormal fluctuations in the drainage volume and air leakage rate is the activity of the target patient. Specifically, if the patient makes a movement of getting out of bed during the treatment, causing the thoracic drainage device to be in a moving state, it is easy to cause the device to tilt, and the drainage bottle will also tilt accordingly, resulting in short-term dynamic fluctuations in the drainage volume recognized by the liquid level sensor. Both excessive and too small drainage volumes may occur. If the patient touches the device unconsciously, such as pressing on the drainage pipeline during sleep, causing the drainage pipeline to be blocked, it will lead to a decrease in the liquid drainage rate and air leakage rate, which will affect the collection of both the drainage volume and the air leakage rate. Another example is accidentally dropping the drainage bottle from the device, which will also affect the collection of the drainage volume and the air leakage rate.

[0076] Under normal circumstances, if it is monitored that the drainage volume of the target patient reaches or exceeds 500 ml, or the air leakage rate reaches or exceeds 40 ml / min, the corresponding timer needs to be cleared and restarted so that all timings of the timer are valid timings. If it is monitored that the drainage volume in 24 hours is less than 500 ml and the air leakage rate for 8 consecutive hours is less than 40 ml / min, the drainage can be stopped.

[0077] However, if the above situation occurs, the collected data cannot reflect the true physical condition of the target patient. If a judgment is made based on this, it may cause the determination timing of stopping drainage to be advanced or delayed. For example, if the drainage volume of the target patient itself is less than 500 ml and the first timer should continue to count, but due to the tilting of the thoracic drainage device, the collected drainage volume is greater than 500 ml, which will cause the first timer to be cleared and start counting again, and ultimately lead to an extension of the determination timing of stopping drainage. Another example, if the drainage volume of the target patient itself is greater than 500 ml and the first timer should be cleared and start counting again, but due to the tilting of the thoracic drainage device / the drainage tube being compressed and blocked / the drainage bottle falling off, the collected drainage volume is less than 500 ml, then the first timer will not be cleared, resulting in an earlier determination timing of stopping drainage. Another example, if the air leakage rate of the target patient itself is greater than 40 ml / min, but due to the drainage tube being compressed and blocked or the drainage bottle falling off, the collected air leakage rate is less than 40 ml / min, it will cause the determination timing of stopping drainage to be delayed.

[0078] In the embodiment of the present application, in order to eliminate the influence of the above factors on the drainage volume and air leakage rate, three types of data need to be obtained in real time. Among them, obtaining the tilting angle of the thoracic drainage device is to determine whether the device is tilted and whether the tilting degree has affected the collection of the drainage volume. Obtaining the pressure difference between the thoracic pressure of the target patient and the pressure of the drainage bottle is to determine whether the drainage tube is blocked and whether the blockage degree has affected the collection of the drainage volume and air leakage rate. Obtaining the NFC tag recognition result of the drainage bottle is to determine whether the drainage bottle has fallen off, thus affecting the collection of the drainage volume and air leakage rate.

[0079] In one embodiment, S6 specifically includes: obtaining the tilting angle of the thoracic drainage device in real time through a tilting angle sensor. A tilting angle sensor is set in the thoracic drainage device. When the device tilts, the tilting angle can be recognized by this sensor. The larger the tilting angle, the more serious the tilting degree.

[0080] In one embodiment, S6 specifically further includes: obtaining the thoracic pressure of the target patient in real time through a first pressure sensor; obtaining the pressure of the drainage bottle in real time through a second pressure sensor; calculating the pressure difference between the thoracic pressure and the pressure of the drainage bottle. A first pressure sensor and a second pressure sensor are set in the thoracic drainage device. The first pressure sensor collects the thoracic pressure p1 in real time, and the second pressure sensor collects the pressure p2 of the drainage bottle in real time. After collection, the pressure difference p1 - p2 between the two is calculated in real time. The larger the difference, the more serious the blockage degree.

[0081] In one embodiment, S6 specifically further includes: recognizing the NFC tag on the drainage bottle in real time through the NFC recognition device to obtain the recognition content; comparing the recognition content with the NFC tag database, and obtaining the NFC tag recognition result according to the comparison result. The thoracic drainage device includes an NFC recognition device, and an NFC tag is provided on the drainage bottle. The NFC tag contains the product serial number or serial number information of the drainage bottle to ensure its uniqueness. All information carried by each NFC tag will be stored in the server to form an NFC tag database, which can be read through the network. The NFC recognition device recognizes the content of the NFC tag in real time to obtain the recognition content, and the recognition content includes the product serial number or serial number information of the drainage bottle. After obtaining the recognition content, the pre-stored NFC tag database is read from the server and compared with the recognition content. If the comparison result indicates that the current NFC tag exists in the database, the obtained NFC tag recognition result is that the tag is correct. If the drainage bottle falls off, no content can be recognized, and the comparison result will be that the current NFC tag does not exist in the database, so the obtained NFC tag recognition result will be that the tag is incorrect.

[0082] S7: Determine whether the drainage pause condition is satisfied at any moment. The drainage pause condition is: the tilt angle is greater than the preset angle, and / or the pressure difference is greater than the threshold value, and / or the NFC tag recognition result is that the tag is incorrect.

[0083] As mentioned in the above steps, three factors are mainly considered to affect the drainage volume: device tilt, drainage tube blockage, and drainage bottle detachment. Therefore, three conditions are set: Condition 1 is that the tilt angle is greater than the preset angle, Condition 2 is that the pressure difference is greater than the threshold value, and Condition 3 is that the NFC tag recognition result is that the tag is incorrect. When the judgment result meets at least one of these three conditions, it is considered that the drainage pause condition is satisfied. Among them, the preset angle is set to 10 degrees. When the tilt angle is greater than 10 degrees, it means that the tilt degree has affected the collection of the drainage volume. Otherwise, it is considered that there is no effect or the effect degree is small and negligible; the threshold value is set to 2 kPa. When the pressure difference between the two is greater than 2 kPa, it means that the blockage degree of the drainage tube has affected the collection of the drainage volume. Otherwise, it is considered that there is no effect or the effect degree is small and negligible; the NFC tag recognition result can be that the tag is correct or the tag is incorrect. When the result is that the tag is incorrect, it means that the drainage bottle has fallen off, which will affect the collection of the drainage volume. Otherwise, it is considered that there is no effect.

[0084] S8: If not, control the first timer to continue timing, and control the drainage device to continue collecting the drainage volume of the target patient; if so, control the first timer to pause timing, and control the drainage device to pause collecting the drainage volume of the target patient. After pausing the timing, continue to perform the operation of judging whether the drainage pause condition is met. When the judgment result is yes, pause the timing and the collection operation. Until the judgment result is no, control the first timer to continue timing from the first pause moment, and control the drainage device to continue collecting the drainage volume of the target patient from the first pause moment.

[0085] When the judgment result is no, it means that none of the above three conditions are met, and there are no such three interference factors currently. At this time, the first timer can continue to time, and the drainage device can also continue to collect the drainage volume of the target patient.

[0086] When the judgment result is yes, it means that at least one of the above three conditions is met, and there is an interference factor currently. At this time, the first timer needs to pause timing, and the drainage device also needs to pause collecting the drainage volume. After pausing, the judgment of whether the drainage pause condition is met continues. If the judgment result is no, it means that the above interference factor has been removed, and both timing and data collection can be carried out normally. At this time, control the first timer to continue timing from the first pause moment, and control the drainage device to continue collecting the drainage volume of the target patient from the first pause moment.

[0087] S9: Judge whether the air leakage pause condition is met at any moment. The air leakage pause condition is: the pressure difference is greater than the threshold value, and / or the NFC tag recognition result is that the tag is incorrect.

[0088] As mentioned in the above steps, two factors are mainly considered for the drainage volume: drainage tube blockage and drainage bottle detachment. Therefore, two conditions are set: Condition 1 is that the pressure difference is greater than the threshold value, and Condition 2 is that the NFC tag recognition result is that the tag is incorrect. When the judgment result meets at least one of these two conditions, it is considered that the air leakage pause condition is met. Among them, the threshold value is set to 2 kPa. When the pressure difference between the two is greater than 2 kPa, it means that the blockage degree of the drainage tube has affected the collection of the air leakage rate. Otherwise, it is considered that there is no effect or the effect degree is small and can be ignored; the NFC tag recognition result can be that the tag is correct or the tag is incorrect. When the result is that the tag is incorrect, it means that the drainage bottle has fallen off, which will affect the collection of the air leakage rate. Otherwise, it is considered that there is no effect.

[0089] S10: If not, control the second timer to continue timing and control the drainage device to continue collecting the air leakage rate of the target patient; if so, control the second timer to pause timing, control the drainage device to pause collecting the air leakage rate of the target patient, and after pausing the timing, continue to perform the judgment operation on whether the air leakage pause condition is met. When the judgment result is yes, pause the timing and the collection operation until the judgment result is no, then control the second timer to continue timing from the second pause moment, and control the drainage device to continue collecting the air leakage rate of the target patient from the second pause moment.

[0090] When the judgment result is no, it means that neither of the above two conditions is met, and there are no such two interference factors currently. At this time, the second timer can continue to time, and the drainage device can also continue to collect the air leakage rate of the target patient.

[0091] When the judgment result is yes, it means that at least one of the above two conditions is met, and there is an interference factor currently. At this time, the second timer needs to pause timing, and the drainage device also needs to pause collecting the air leakage rate. After pausing, the judgment on whether the air leakage pause condition is met continues. If the judgment result is no, it means that the above interference factor has been removed, and both timing and data collection can proceed normally. At this time, control the second timer to continue timing from the second pause moment, and control the drainage device to continue collecting the air leakage rate of the target patient from the second pause moment.

[0092] S11: When the cumulative duration of the first timer is equal to the first duration and the cumulative duration of the second timer is not less than the second duration, control the drainage setting to stop drainage, where the second duration is less than the first duration.

[0093] The first timer times based on the above mechanism, and all timings are valid timings. When its cumulative duration is equal to the first duration, it means that the drainage volume less than 500 ml has been counted for 24 hours. During this period, all timings of the second timer are also valid timings. Based on the extubation guideline, the second duration is set to 8 hours. If the cumulative duration of the second timer is not less than 8 hours at this time, it means that the state of the air leakage rate less than 40 ml / min has lasted for at least 8 hours. When both of the above two conditions are met, it is considered that the condition for stopping drainage has been met, and at this time, the drainage device can be controlled to stop drainage.

[0094] In one embodiment, after S1, it further includes:

[0095] S12: Monitor in real time whether a shutdown signal is received.

[0096] In addition to the above three interference factors, there is another factor that affects timing, which is equipment shutdown. The shutdown may be an active shutdown by medical staff for treatment purposes, or an accidental shutdown caused by the target patient's misoperation or equipment failure. In the prior art, once the timing starts, it will not stop. Even in the case of shutdown, the timing still continues, which may also lead to inaccurate determination of the timing for stopping drainage. In this step, after the timing starts, it is also necessary to continuously monitor whether a shutdown signal is received.

[0097] S13: If so, control the first timer and the second timer to pause timing, and control the drainage device to pause collecting the drainage volume and air leakage rate of the target patient until a power-on signal is received. Then, control the first timer and the second timer to continue timing from the third pause moment, and control the drainage device to continue collecting the drainage volume and air leakage rate of the target patient from the third pause moment.

[0098] If a shutdown signal is received, both the first timer and the second timer need to pause timing, and at the same time, the collection of the drainage volume and air leakage rate also needs to be paused. After the pause, if a power-on signal is received, it means that the equipment continues to work normally, and the timing and data collection work can also proceed normally. At this time, control the first timer and the second timer to continue timing from the third pause moment, and control the drainage device to continue collecting the drainage volume and air leakage rate of the target patient from the third pause moment.

[0099] Through this step, the interference of the shutdown factor on timing can be eliminated, making the timing more accurate.

[0100] In one embodiment, the thoracic drainage device further includes an alarm. If the drainage pause condition that is satisfied is that the pressure difference is greater than the threshold and / or the NFC tag recognition result is that the tag is incorrect, in addition to pausing timing and pausing the collection of the drainage volume, a first warning message can also be generated, and control the alarm to give an alarm based on the first warning message.

[0101] When at least one of the above two conditions for the drainage pause is satisfied, it means that the drainage tube is blocked and / or the drainage bottle has fallen off, both of which will affect the subsequent normal drainage work. Therefore, if these situations are monitored, a first warning signal can be generated and the alarm can be used to give an alarm, so that the patient himself or the medical staff can timely learn of this abnormal situation and deal with it, enabling the drainage work to resume normal as soon as possible.

[0102] In one embodiment, if the air leakage pause condition that is satisfied is that the pressure difference is greater than the threshold and / or the NFC tag recognition result is that the tag is incorrect, a second warning message can also be generated, and control the alarm to give an alarm based on the second warning message.

[0103] Similarly, when at least one of the above-mentioned air leakage pause conditions is met, it indicates that the drainage tube is blocked and / or the drainage bottle has fallen off, both of which will affect the subsequent normal drainage work. Therefore, if these situations are detected, a second warning signal can be generated and an alarm can be given through the alarm, so that the patient himself or the medical staff can be informed of the abnormal situation in a timely manner and take corresponding measures to resume the drainage work as soon as possible.

[0104] In one embodiment, after S11, it further includes:

[0105] S14: Generate extubation information and send the extubation information to the control platform.

[0106] The thoracic drainage device is connected to the control platform. The thoracic drainage device can send various data during the drainage process to the control platform. Medical staff can obtain these data from the control platform, understand the current drainage status of the target patient based on these data, and take corresponding measures. In the above steps, since the determination of the drainage volume and the air leakage rate both meet the extubation criteria, the thoracic drainage device can stop drainage, and at the same time, it can generate extubation information and send it to the control platform so that the medical staff can know that the current extubation conditions are met. After receiving this information, the medical staff can pull out the drainage tube from the target patient's chest cavity and stop the treatment.

[0107] As can be seen from the above embodiments, for the control method of the thoracic drainage device provided in the present application, due to the setting of a reasonable timing reset and timing pause mechanism, the timing will only be determined based on the data fluctuations under normal conditions of the patient, excluding the interference of abnormal factors such as device tilt, drainage tube blockage, and drainage bottle falling off. Therefore, the determination of the timing to stop drainage can be made more accurately.

[0108] As Figure 3 shown, it is a comparison schematic diagram of the timing methods of the prior art and the present application. Figure 3 Taking the timing of the drainage volume as an example, and assuming that the drainage volume of the patient under normal conditions is less than 500 ml and the air leakage rate is less than 40 ml / min.

[0109] In the prior art, starting from time A, if the patient gets out of bed and moves at time B, resulting in the drainage volume monitored at time B being greater than 500 ml, the cumulative duration t1 from time A to time B needs to be reset to zero, and re-timing starts from time B. If the patient gets out of bed and moves again at time C, resulting in the drainage volume monitored at time C also being greater than 500 ml, the cumulative duration t2 from time B to time C needs to be reset to zero again, and re-timing starts from time C until time D is reached, and the cumulative timing t3 is equal to 24 hours, and it is determined that the timing of the drainage volume meets the stop drainage criteria. The total time consumed in the whole process is t1 + t2 + t3.

[0110] In the embodiment of the present application, starting from time A, if the patient gets out of bed and moves at time B, causing the tilt angle of the device to be greater than 10 degrees, the timing is paused at time B, and the collection of the drainage volume is suspended. The accumulated duration t1 is retained. After the tilt situation of the device is restored, the timing continues. If the patient gets out of bed and moves again at time C, causing the tilt angle of the device to be greater than 10 degrees again, the timing is paused at time C, and the collection of the drainage volume is suspended. The accumulated duration t1 + t4 is retained. After the tilt situation of the device is restored, the timing continues until time E is reached. The accumulated timing t1 + t4 + t5 is equal to 24 hours, and it is determined that the timing of the drainage volume meets the stop drainage index. The total time consumed in the whole process is t1 + t4 + t5. Compared with the prior art, the timing of stopping drainage is advanced by t1 + t2, and the treatment efficiency is improved and resources are saved.

[0111] As Figure 4 shown, it is the second process schematic diagram of the control method of the thoracic drainage device provided by the embodiment of the present application. The following will be described in detail Figure 4 the working process in the above embodiment as a whole.

[0112] At the beginning, first configure the stop drainage index, specifically that the drainage volume in 24 hours is less than 500 ml, and the air leakage rate in 8 consecutive hours is less than 40 ml / min. Determine whether the device is started. If so, start the first timer and the second timer and time respectively. If not, it means the device is paused. Pause the first timer and the second timer until the device is restarted, and then the first timer and the second timer continue to time.

[0113] Before 24 hours are reached, determine in real time whether the drainage volume is not less than 500 ml. If so, clear the first timer and start timing again. If not, continue timing. In addition, determine in real time whether the tilt angle of the device is greater than 10 degrees. If so, pause the first timer and continue to judge this condition until it is not greater than 10 degrees, and then continue timing. Determine in real time whether p1 - p2 is greater than 2 kPa. If so, it means the drainage tube is blocked. Pause the first timer and give an alarm, and continue to judge this condition until it is not greater than 2 kPa, and then continue timing. Determine in real time whether the NFC label of the drainage bottle is incorrect. If so, it means the drainage bottle has fallen off. Pause the first timer and give an alarm, and continue to judge this condition until the label is correct, and then continue timing. Finally, determine whether the accumulated duration of the first timer is not less than 24 hours. If not, continue timing. If so, it is determined that the drainage volume meets the stop drainage index.

[0114] Real-time judge whether the air leakage rate is not less than 40 ml / min. If so, clear the second timer and restart the timing. If not, continue the timing. In addition, real-time judge whether p1 - p2 is greater than 2 kPa. If so, it indicates that the drainage tube is blocked. Pause the second timer and give an alarm, and continue to judge this condition until it is not greater than 2 kPa, then continue the timing. Real-time judge whether the NFC tag of the drainage bottle is incorrect. If so, it indicates that the drainage bottle has fallen off. Pause the second timer and give an alarm, and continue to judge this condition until the tag is correct, then continue the timing. Finally, judge whether the cumulative duration of the second timer is not less than 8 hours. If not, continue the timing. If so, it is determined that the air leakage rate meets the drainage stop index.

[0115] When both the drainage volume and the air leakage rate meet the drainage stop index, it is determined that this moment is the drainage stop time point, control the device to stop drainage, and notify the medical staff to perform the tube removal operation. Through the above process, the determination of the drainage stop time point is relatively accurate, thus improving the efficiency and saving resources.

Therefore, the determination of the timing to stop drainage can be made more accurate.
