Description

[0002] Chest drainage is an important medical treatment method for draining gas, liquid, and the like in the chest cavity to restore the normal physiological function of the chest cavity. Current chest drainage devices mainly monitor the drainage volume and air leakage volume during the drainage process, and then determine whether the tube needs to be removed according to whether the two meet the reference indicators. After the tube is removed, in order to understand the treatment effect, a separate puncture is often performed to measure the pleural pressure of the patient after treatment, so as to determine the recovery of the patient.

[0003] However, on the one hand, if the measured pleural pressure does not meet the recovery indicators, it may be necessary to drain again, and the current reference of the drainage volume and the air leakage volume to determine the tube removal time is not accurate enough; on the other hand, the above pleural pressure measurement process and the drainage process are independent of each other, and the obtained pleural pressure data is discrete data, which is not accurate enough to determine whether the patient has recovered based on the data.

Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0048] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a chest drainage device applicable to the chest cavity data monitoring method provided in this application embodiment. The chest drainage device includes a drainage bottle 100, a main unit 200, a drainage component 300 connected to the main unit 200 and the drainage bottle 100, and a breathing component 400 connected to the main unit 200. The drainage component 300 and the breathing component 400 are used to access the chest cavity. The chest drainage device includes an alternating drainage mode and a breathing mode. The drainage component 300 is used to perform drainage in the drainage mode and to pause drainage in the breathing mode. The breathing component 400 is used to monitor respiratory pleural pressure in the breathing mode.

[0049] The main unit 200 has control functions, which can control related hardware to execute relevant programs according to user input commands to complete the drainage of the pleural cavity and monitor various pleural data during the drainage process until the patient's indicators return to normal and drainage is stopped. The drainage bottle 100 is assembled with the main unit 200 and is used to collect pleural fluid. The main unit 200 has a drainage mode and a breathing mode, which alternate multiple times during the period from the start to the stop of drainage. The first end of the drainage assembly 300 is used to connect to the pleural cavity, the second end is connected to the main unit 200, and the third end is connected to the drainage bottle 100. The first end of the breathing assembly 400 is used to connect to the pleural cavity, and the second end is connected to the main unit 200.

[0050] The drainage mode is used to manually drain pleural fluid from the patient's chest cavity, allowing the patient's chest function to gradually recover. In the drainage mode, the main unit 200 can control the drainage component 300 and other related components to work together to complete the drainage of pleural fluid, so that the pleural fluid flows along the first end of the drainage component 300 to the third end, and finally enters the drainage bottle 100. As the drainage proceeds, the patient's chest function gradually recovers. During the drainage process, the main unit 200 can control the drainage component 300 to measure real-time drainage volume data and real-time air leakage volume data.

[0051] The breathing mode is used to monitor the pleural pressure data of a patient after a period of drainage treatment, without the aid of external power from the device, relying solely on their own breathing. For ease of representation, the pleural pressure data in this state will be referred to as real-time respiratory pleural pressure data in the following embodiments of this application. In the breathing mode, the host 200 can control the drainage component 300 and other related components to work together to pause drainage, so that the breathing component 400 is not disturbed by the drainage component 300, and at the same time control the breathing component 400 to measure the patient's real-time respiratory pleural pressure data.

[0052] After obtaining the aforementioned pleural data, the host computer 200 will process this data to determine the appropriate time for the pleural drainage device to stop operating and generate a corresponding stop-operation prompt message. In the following embodiments, this will be combined with... Figure 1 The process of determining when to stop working is explained in detail.

[0053] Please see Figure 2 , Figure 2 This is a schematic flowchart of the first method for monitoring thoracic cavity data provided in the embodiments of this application. The method specifically includes:

[0054] S1: In drainage mode, real-time drainage volume data and real-time leakage volume data are obtained from the drainage component; in breathing mode, real-time respiratory pleural pressure data are obtained from the breathing component.

[0055] In drainage mode, the drainage component 300 can drain pleural fluid and monitor real-time drainage volume and leakage flow rate data. The main unit 200 can acquire this data from the drainage component 300. The unit for real-time drainage volume data can be ml, and the unit for real-time leakage flow rate data can be ml / min. In respiratory mode, the respiratory component 400 can monitor real-time respiratory pleural pressure data, and the main unit 200 can acquire this data from the respiratory component 400. Real-time respiratory pleural pressure data includes end-expiratory and end-inspiratory data, and the unit is mmHg.

[0056] In one embodiment, the breathing assembly includes a breathing pressure tubing and a breathing pressure sensor. A first inlet end of the breathing pressure tubing is connected to the pleural cavity, and a first outlet end of the breathing pressure tubing is connected to the breathing pressure sensor. The breathing pressure sensor is connected to the main unit. S1 specifically includes:

[0057] S11: Acquire real-time respiratory pleural pressure data from the respiratory pressure sensor.

[0058] Both the first inlet end 41 of the respiratory pressure tubing 401 and the first end of the drainage assembly 300 are connected to the pleural cavity. The first outlet end 42 can be connected to the respiratory pressure sensor 402 via the first connecting tube 21. The respiratory pressure sensor 402 is installed in the host unit 200 and electrically connected to the host unit 200. In respiratory mode, the host unit 200 controls the respiratory pressure sensor 402 to measure real-time respiratory pleural pressure data through the respiratory pressure tubing 401, and the host unit 200 can acquire this data. In drainage mode, the host unit 200 controls the respiratory pressure sensor 402 to pause measurement.

[0059] In one embodiment, the drainage assembly includes a main drainage pipe, a drainage pressure pipe, a first drainage pressure sensor, a second drainage pressure sensor, a liquid level sensor, and a negative pressure pump. The second inlet end of the main drainage pipe and the third inlet end of the drainage pressure pipe are used to connect to the pleural cavity. The second outlet end of the main drainage pipe, the first drainage pressure sensor, and the negative pressure pump are all connected to a drainage bottle. The third outlet end of the drainage pressure pipe is connected to the second drainage pressure sensor. The first drainage pressure sensor, the second drainage pressure sensor, the liquid level sensor, and the negative pressure pump are all connected to the main unit. S1 further includes:

[0060] S12: Obtain real-time liquid level data of the drainage bottle from the liquid level sensor, and obtain real-time drainage volume data based on the real-time liquid level data;

[0061] S13: Obtain real-time drive data of the negative pressure pump, and obtain real-time drainage bottle pressure data from the first drainage pressure sensor and real-time drainage pleural pressure data from the second drainage pressure sensor. Based on the real-time drainage bottle pressure data, real-time drainage pleural pressure data and real-time drive data, obtain real-time air leakage flow data.

[0062] The first end of the drainage assembly 300 includes a second inlet end 31 of the main drainage pipe 301 and a third inlet end 33 of the drainage pressure pipe 302, which are interconnected and connected to the patient's pleural cavity. The second end of the drainage assembly 300 includes a third outlet end 34 of the drainage pressure pipe 302. A second drainage pressure sensor 304 is disposed in the main unit 200 and electrically connected to the main unit 200. The third outlet end 34 of the drainage pressure pipe 302 can be connected to the second drainage pressure sensor 304 through a second connecting pipe 22. The third end of the drainage assembly 300 includes the second outlet end 34 of the main drainage pipe 301. The second outlet end 34 of the main drainage pipe 301, the second drainage pressure sensor 304, and the negative pressure pump 305 are all connected to the drainage bottle 100. A liquid level sensor ( Figure 1 (Not shown) is set inside and / or outside the drainage bottle 100. The type and setting method of the liquid level sensor can be selected as needed. The second outlet end 34, the second drainage pressure sensor 304, the liquid level sensor and the negative pressure pump 305 are all electrically connected to the main unit 200.

[0063] In drainage mode, the host 200 controls the negative pressure pump 305 to operate under set negative pressure, so that the pressure inside the drainage bottle 100 is lower than the pleural pressure. Under the pressure difference, the pleural fluid will flow into the drainage bottle 100 through the main drainage pipe 301. As drainage proceeds, the liquid level in the drainage bottle 100 gradually rises. The real-time changes in the liquid level can be monitored by the liquid level sensor to obtain real-time liquid level data. The host 200 can obtain this data from the liquid level sensor and process it to obtain real-time drainage volume data.

[0064] In drainage mode, the host 200 controls the first drainage pressure sensor 303 to measure real-time drainage bottle pressure data, and controls the second drainage pressure sensor 304 to measure the patient's pleural pressure data during drainage via the drainage pressure tubing 302. For ease of representation, in the following embodiments, the pleural pressure data in this state will be referred to as real-time drainage pleural pressure data. This data can be used to reflect whether the patient's pleural pressure has reached the aforementioned set negative pressure during drainage. After measurement, the host 200 can obtain these two types of data from the first drainage pressure sensor 303 and the second drainage pressure sensor 304.

[0065] Furthermore, when the host 200 controls the negative pressure pump 305 to operate under negative pressure, it needs to control the negative pressure pump 305 based on pre-set real-time drive data. The real-time drive data can be drive power or the duty cycle corresponding to the drive power, etc. The real-time leakage flow rate data is mainly calculated based on the real-time drainage pleural pressure data and the real-time drive data. Specifically, a model is pre-established based on the drainage bottle pressure data, drainage pleural pressure data, drive data, and leakage flow rate data. After obtaining the real-time drainage bottle pressure data, real-time drainage pleural pressure data, and real-time drive data, the host 200 inputs these three data into the model to calculate the real-time leakage flow rate data.

[0066] In one embodiment, the chest drainage device further includes a hollow connector 500, which includes three first interfaces 51 and at least one second interface 52. The three first interfaces 51 are respectively connected to a second inlet end 31, a third inlet end 33 and a first inlet end 41, and the second interface 52 is used to access the chest cavity.

[0067] Because connector 500 is hollow, the three tubes can be connected inside connector 500 through three first interfaces 51, and then connected to the pleural cavity through a single second interface 52. Connector 500 may or may not have a sampling port 53, depending on the specific needs. Since connector 500 can connect three tubes to the pleural cavity simultaneously through a single puncture point, no additional puncture point is needed when measuring real-time respiratory pleural pressure data, thus reducing the risk of infection and improving safety. It should be noted that... Figure 1 The structure of the connector 500 is only one schematic diagram. The connector 500 can also be other models. This application does not limit the model of the connector 500, as long as it can simultaneously connect three tubes to the thoracic cavity.

[0068] In one embodiment, a one-way valve is provided inside the drainage pressure tubing. The one-way valve opens when the current pleural pressure is negative and closes when the current pleural pressure is positive. No one-way valve is provided inside the respiratory pressure tubing. S13 specifically includes:

[0069] S131: Obtain real-time drainage pleural pressure data of negative pressure from the second drainage pressure sensor.

[0070] S132: Acquire real-time respiratory pleural pressure data (positive or negative) from a respiratory pressure sensor.

[0071] like Figure 3 As shown, Figure 1 Please also refer to the cross-sectional diagram at point A. Figure 1 and Figure 3 When the current pleural pressure is negative, the one-way valve 306 opens; when the current pleural pressure is negative, the one-way valve 306 closes. The breathing pressure line 401 does not have a one-way valve 306 installed inside.

[0072] In existing chest drainage equipment, in addition to measuring real-time pleural pressure data, the drainage pressure line 302 also needs to be connected to the vent valve (not shown in the figure) inside the main unit 200. To ensure safety, a one-way valve 306 needs to be installed inside the drainage pressure line 302. In other words, the one-way valve 306 is an indispensable component.

[0073] Normally, when the pleural pressure is negative, the one-way valve 306 is open. At this time, a passage is formed between the drainage pressure tubing 302, the main drainage tubing 301, and the pleural cavity. Because the pressure inside the drainage bottle 100 is lower than the pressure inside the drainage pressure tubing 302, pleural fluid will not enter the drainage pressure tubing 302 when the one-way valve 306 is open. The second drainage pressure sensor 304 can measure the patient's real-time drainage pleural pressure data through the drainage pressure tubing 302, and the measured real-time drainage pleural pressure data is always negative. However, if the pleural pressure is abnormally positive, the one-way valve 306 will close. At this time, no passage is formed between the drainage pressure tubing 302 and the main drainage tubing 301. Fluid in the main drainage tubing 301 and the drainage bottle 100 will be blocked by the one-way valve 306 and cannot enter the drainage pressure tubing 302, thus ensuring the safety of the drainage pressure tubing 302 and its connected components. Therefore, with the above structure, the second drainage pressure sensor 304 can only measure negative pleural pressure, but cannot measure positive pleural pressure. The real-time drainage pleural pressure data obtained by the host 200 from the second drainage pressure sensor 304 is always negative.

[0074] As can be seen from the above, due to the presence of the one-way valve 306, the original drainage pressure line 302 and the second drainage pressure sensor 304 in the device can only measure negative pressure. However, respiratory pleural pressure can be both positive and negative. If only a breathing mode is added to the existing device, the original drainage pressure line 302 and the second drainage pressure sensor 304 can only measure negative respiratory pleural pressure, not positive respiratory pleural pressure. This will make the measured real-time drainage pleural pressure data inaccurate and incomplete. In other words, based on the current hardware structure of the chest drainage device, it is not possible to obtain positive respiratory pleural pressure solely through software algorithms; the hardware structure must be modified.

[0075] Therefore, in this embodiment, without modifying the original drainage component 300, by adding a respiratory pressure line 401 and a respiratory pressure sensor 402 to the existing chest drainage device, and without installing a one-way valve 306 inside the respiratory pressure line 401, the respiratory pressure sensor 402 can measure both positive and negative pleural pressure, obtaining accurate and complete real-time drainage pleural pressure data. The host 200 can obtain real-time respiratory pleural pressure data (positive or negative) from the respiratory pressure sensor 402. Since this solution does not require significant modifications to the existing chest drainage device structure, it is low-cost and highly practical.

[0076] In the prior art, the second drainage pressure sensor 304 of the chest drainage device can only measure negative pressure, so it is only a negative pressure sensor. However, the respiratory pressure sensor 402 in this embodiment needs to measure both positive and negative pressure, so it needs to be set as a positive and negative pressure sensor to meet clinical needs.

[0077] In one embodiment, the drainage assembly further includes an isolating switch, which is disposed on the drainage path of the main drainage pipeline, and S1 specifically includes:

[0078] S14: In drainage mode, control the isolation switch to open so that a passage is formed between the drainage bottle and the breathing pressure tubing, and obtain real-time drainage volume data and real-time leakage flow data from the drainage assembly.

[0079] S15: In breathing mode, control the isolation switch to close so that no passage is formed between the drainage bottle and the breathing pressure line, and obtain real-time respiratory pleural pressure data from the breathing assembly.

[0080] Since both the main drainage line 301 and the respiratory pressure line 401 are connected to the pleural cavity, and the main drainage line 301 is also connected to the drainage bottle 100, a pathway is formed between the drainage bottle 100, the main drainage line 301, and the respiratory pressure line 401. In respiratory mode, although the drainage assembly 300 stops drainage, this pathway causes the gas in the drainage bottle 100 and the main drainage line 301 to interfere with the measurement of respiratory pleural pressure, resulting in inaccurate measurement results.

[0081] In this embodiment, by setting an isolating switch 307 on the drainage path of the main drainage pipe 301, when entering the drainage mode, the host 200 controls the isolating switch 307 to open, thus maintaining the aforementioned pathway and not affecting the normal drainage operation of the drainage component 300. At this time, real-time drainage volume data and real-time leakage flow data can be normally obtained from the drainage component 300. When entering the breathing mode, the host 200 controls the isolating switch 307 to close, cutting off the aforementioned pathway, eliminating the aforementioned interference, and improving the accuracy of the real-time respiratory pleural pressure data obtained by the host 200. Without affecting the normal drainage function, the isolating switch 307 can be positioned as close as possible to the second inlet end 31 of the main drainage pipe 301 to minimize the impact of the main drainage pipe 301 on respiratory pleural pressure. Specifically, the isolating switch 307 can be a solenoid valve, set on the drainage path of the main drainage pipe 301 via a switch base 308. The solenoid valve can receive electrical signals from the host 200 and automatically open and close, eliminating the need for manual opening and closing.

[0082] S2: Based on real-time drainage volume data, real-time air leakage volume data, real-time respiratory pleural pressure data, and current working time, obtain continuous drainage volume data, continuous air leakage volume data, and continuous respiratory pleural pressure data.

[0083] Real-time drainage volume data, real-time air leakage volume data, and real-time respiratory pleural pressure data are all discrete data. By centralizing and classifying the discrete data at each moment within the current working time, continuous drainage volume data, continuous air leakage volume data, and continuous respiratory pleural pressure data can be obtained. The current working time refers to the total duration from the start time of first entering the drainage mode to the current moment.

[0084] S3: Determine whether the conditions for stopping operation are met at any given time. The conditions for stopping operation are that the continuous drainage flow data, continuous air leakage flow data, and continuous respiratory pleural pressure data all meet the corresponding reference indicators.

[0085] After obtaining the above three types of data, the host 200 can determine at any time whether the chest drainage device meets the conditions for stopping operation based on these three types of data and their respective three reference indicators. The condition is that the above three types of data simultaneously meet their respective three reference indicators. Specifically, the conditions for stopping operation can be that the drainage volume for 24 consecutive hours is less than 500ml, the air leakage flow for 8 consecutive hours is less than 40ml / min, the end-expiratory pressure for 24 consecutive hours is within the range of -5 to -3mmHg, and the end-inspiratory pressure for 24 consecutive hours is within the range of -10 to -5mmHg.

[0086] The above judgment can be performed at any time after the device starts running, but this application is not limited to this. To reduce the computational load, the judgment can also be performed only once after each breathing mode ends, with data monitored at other times. Those skilled in the art can choose to perform the judgment at any time or only at the above-mentioned end time, depending on actual needs.

[0087] S4: If so, generate a stop-work prompt message.

[0088] If the judgment result is yes, it means that the drainage effect is good and the drainage can be stopped. At this time, the host 200 can generate a stop working prompt message and output the message individually or in combination through the human-computer interaction device of the chest drainage device in the form of text, sound, images, etc., so that relevant personnel can obtain the information in a timely manner and perform subsequent tube removal operations based on the information.

[0089] In one embodiment, prior to S1, the following is also included:

[0090] Sa: Get the mode switching parameters for drainage mode and breathing mode.

[0091] Sb: Based on the mode switching parameters, determine the switching order of the drainage mode and the breathing mode, as well as the first duration of the drainage mode and the second duration of the breathing mode, with the first duration being longer than the second duration.

[0092] The mode switching parameters include the entry order and duration of each mode, which need to be preset and stored in the host 200. Before executing step S1, the host 200 first obtains these parameters, and then determines the mode to enter first as drainage mode, which needs to last for a first duration, followed by switching to respiratory mode, which needs to last for a second duration. After determining this information, the host 200 controls the relevant components in the chest drainage device to perform the first mode entry and mode switching operations based on this information. If the shutdown condition in S3 is not met after the two modes have ended, the host 200 will control the relevant components in the chest drainage device to continue performing the second mode entry and mode switching operations based on the above information, and so on. To balance better drainage efficiency and sufficient respiratory pleural pressure data, the first duration will be longer than the second duration. For example, the first duration is 5 minutes, and the second duration is 30 seconds.

[0093] Using the above method, after setting the mode switching parameters, the chest drainage device can automatically complete each mode operation and mode switching operation without manual intervention, which is highly efficient.

[0094] In one embodiment, after S4, the method further includes:

[0095] S5: If not, determine whether the current continuous respiratory pleural pressure data meets the corresponding reference indicators.

[0096] S6: If so, extend the first duration or shorten the second duration to obtain the updated mode switching parameters.

[0097] If the judgment result in S3 is negative, it means that at least one of the above three types of data does not meet the corresponding reference indicator. In this case, it is possible to further determine which specific situation is not met. If the current continuous respiratory pleural pressure data meets the corresponding reference indicator, but other types of data do not, it means that the need for drainage is more urgent than the acquisition of real-time respiratory pleural pressure data, or that the current continuous respiratory pleural pressure data already indicates that the respiratory pleural pressure is normal, and the drainage process can be accelerated to achieve early extubation. Therefore, in this situation, the host 200 can extend the first duration, for example, from 5 minutes to 8 minutes, or shorten the second duration, for example, from 30 seconds to 15 seconds, using the extended first duration or the shortened second duration to update the initially set mode switching parameters. In the next execution of the mode entry and mode switching operations, the host 200 controls the relevant components to perform the operations based on the updated mode switching parameters.

[0098] Using the above methods, the host 200 can automatically speed up the traffic diversion process according to the actual situation, thus improving work efficiency.

[0099] like Figure 4 The diagram shown is a second flowchart illustrating the method for monitoring thoracic cavity data provided in this application embodiment. The following is a detailed explanation... Figure 4 The working process in the above embodiments will be described in general.

[0100] Initially, the host 200 initializes drainage volume data, air leakage flow data, and respiratory pleural pressure data. Then, based on preset mode switching parameters, it enters drainage mode. At this time, the isolation switch 307 is in the open state to create a pathway between the drainage bottle 100 and the pleural cavity. The host 200 controls the drainage component 300 to acquire real-time drainage volume data and real-time air leakage flow data. The host 200 determines whether the switching time for the respiratory mode has been reached based on the mode switching parameters. If the result is no, it continues to monitor the real-time drainage volume data and real-time air leakage flow data. If the result is yes, the host 200 controls the drainage component 300 to pause drainage and enter respiratory mode. At this time, the isolation switch 307 is in the closed state to prevent a pathway from being formed between the drainage bottle 100 and the respiratory component 400. The host 200 controls the respiratory component 400 to acquire real-time respiratory pleural pressure data and determines whether the stop-work conditions are met. The stop-work conditions are that the continuous drainage volume data, continuous air leakage flow data, and continuous respiratory pleural pressure data under the current working time all meet their respective reference indicators. If the judgment result is negative, the process re-enters the drainage mode and repeats the above steps. If the judgment result is positive, a stop-work prompt message is generated and output through the human-computer interaction device, ending the process. Relevant personnel can promptly obtain this information and perform subsequent tube removal operations based on it.

[0101] As can be seen from the above embodiments, the method for monitoring pleural data provided in this application sets up alternating drainage and breathing modes in the pleural drainage device, and adds a breathing component. The original drainage component performs drainage in the drainage mode and pauses drainage in the breathing mode. The newly added breathing component monitors respiratory pleural pressure in the breathing mode. The host first obtains real-time drainage volume data and real-time air leakage flow data from the drainage component in the drainage mode, and obtains real-time respiratory pleural pressure data from the breathing component in the breathing mode. Then, based on the real-time drainage volume data, real-time air leakage flow data, real-time respiratory pleural pressure data, and current working time, it obtains continuous drainage volume data, continuous air leakage flow data, and continuous respiratory pleural pressure data. Then, it determines whether the stop working condition is met at any time. The stop working condition is that the continuous drainage volume data, continuous air leakage flow data, and continuous respiratory pleural pressure data all meet the corresponding reference indicators. If so, a stop working prompt message is generated. This application determines that the operation needs to be stopped only when the continuous drainage volume data, continuous air leakage volume data, and continuous respiratory pleural pressure data all meet the reference indicators. Moreover, the determination is based on the continuous respiratory pleural pressure data rather than discrete data. Therefore, secondary drainage is not required. In other words, this application is more accurate in determining when the chest drainage device should be stopped.

[0102] Based on the methods described in the above embodiments, this embodiment will further describe the method from the perspective of a chest cavity data monitoring device. This device is suitable for chest drainage equipment, which includes a drainage bottle, a main unit, a drainage component connected to the main unit and the drainage bottle, and a breathing component connected to the main unit.

[0112] In one embodiment, the drainage pressure line is equipped with a one-way valve. When the current pleural pressure is negative, the one-way valve opens; when the current pleural pressure is positive, the one-way valve closes. The respiratory pressure line is not equipped with the one-way valve. The first acquisition unit is used to acquire real-time respiratory pleural pressure data (positive or negative) from the respiratory pressure sensor.

[0122] Unlike existing technologies, the pleural data monitoring device provided in this application only determines that it needs to stop working when the continuous drainage volume data, continuous air leakage volume data, and continuous respiratory pleural pressure data all meet the reference indicators. Moreover, the determination is based on the continuous respiratory pleural pressure data rather than discrete data, so secondary drainage is not required. In other words, this application is more accurate in determining when the pleural drainage device should stop working.
