The method sets an alternating drainage mode and a breathing mode in a thoracic cavity drainage device, and adds a breathing component. The original drainage component performs drainage in the drainage mode and suspends drainage in the breathing mode. The added breathing component performs breathing pleural pressure monitoring in the breathing mode.

Description

TECHNICAL FIELD

[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 DESCRIPTION

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.

[0048] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the chest drainage device to which the chest data monitoring method provided by the embodiments of the present application is applicable, the chest drainage device comprising a drainage bottle 100, a host computer 200, a drainage assembly 300 connected with the host computer 200 and the drainage bottle 100, and a breathing assembly 400 connected with the host computer 200, the drainage assembly 300 and the breathing assembly 400 being used for accessing a chest cavity, the chest drainage device comprising an alternating drainage mode and a breathing mode, the drainage assembly 300 being used for performing drainage in the drainage mode and suspending drainage in the breathing mode, and the breathing assembly 400 being used for performing breathing pleural pressure monitoring in the breathing mode.

[0049] The host computer 200 has a control function, can control relevant hardware to execute relevant programs according to various instructions input by a user, so as to complete the drainage of the chest cavity and the monitoring operation of various chest data in the drainage process, until the patient indicators are normal and the drainage is stopped. The drainage bottle 100 is assembled with the host computer 200, and is used for collecting chest cavity liquid. The host computer 200 has the drainage mode and the breathing mode, and the drainage mode and the breathing mode are alternately performed multiple times in the time period from starting drainage to stopping drainage. The first end of the drainage assembly 300 is used for accessing the chest cavity, the second end is connected with the host computer 200, and the third end is connected with the drainage bottle 100. The first end of the breathing assembly 400 is used for accessing the chest cavity, and the second end is connected with the host computer 200.

[0050] The drainage mode is used to artificially provide power to drain the patient's chest cavity liquid, so that the patient's chest cavity function gradually recovers. In the drainage mode, the host 200 can control the drainage assembly 300 and other related components to jointly complete the drainage of the chest cavity liquid, so that the chest cavity liquid flows along the first end to the third end of the drainage assembly 300, and finally enters the drainage bottle 100. As the drainage proceeds, the patient's chest cavity function gradually recovers. During the drainage process, the host 200 can control the drainage assembly 300 to measure real-time drainage volume data and real-time air leakage flow data.

[0051] The breathing mode is used to monitor the pleural pressure data of the patient in a state of relying only on self-breathing without the aid of external power after a period of drainage treatment. For convenience of representation, the pleural pressure data in this state are referred to as real-time breathing pleural pressure data in the following embodiments of the present application. In the breathing mode, the host 200 can control the drainage assembly 300 and other related components to jointly suspend the drainage, so that the breathing assembly 400 is not disturbed by the drainage assembly 300, and simultaneously control the breathing assembly 400 to measure the real-time breathing pleural pressure data of the patient.

[0052] After monitoring the above chest cavity data, the host 200 processes the chest cavity data to determine the stopping working time of the chest drainage device and generate corresponding stopping working prompt information. In the following embodiments, the process of how to determine the stopping working time will be described in detail. Figure 1 The process of how to determine the stopping working time will be described in detail.

[0053] Please refer to Figure 2 , Figure 2 is the first flowchart of the chest cavity data monitoring method provided by the embodiments of the present application, and the method specifically comprises:

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

[0055] In the drainage mode, the drainage assembly 300 can drain the chest cavity liquid and monitor the real-time drainage volume data and the real-time air leakage flow data of the drainage process, and the host 200 can obtain these data from the drainage assembly 300. The unit of the real-time drainage volume data can be ml, and the unit of the real-time air leakage flow data can be ml / min. In the breathing mode, the breathing assembly 400 can monitor the real-time breathing pleural pressure data, and the host 200 can obtain these data from the breathing assembly 400. The real-time breathing pleural pressure data include the end of expiration and the end of inspiration, and the unit is mmHg.

[0056] In an embodiment, the breathing assembly comprises a breathing pressure pipeline and a breathing pressure sensor, a first inlet end of the breathing pressure pipeline is used for accessing the thoracic cavity, a first outlet end of the breathing pressure pipeline is connected with the breathing pressure sensor, the breathing pressure sensor is connected with the host computer, and S1 specifically comprises:

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

[0058] The first inlet end 41 of the breathing pressure pipeline 401 and the first end of the drainage assembly 300 are both accessed into the thoracic cavity, the first outlet end 42 can be connected with the breathing pressure sensor 402 through the first connecting pipeline 21, the breathing pressure sensor 402 is arranged in the host computer 200 and is electrically connected with the host computer 200. The host computer 200 controls the breathing pressure sensor 402 to measure the real-time respiratory pleural pressure data through the breathing pressure pipeline 401 in the breathing mode, and the host computer 200 can acquire the data. In the drainage mode, the host computer 200 controls the breathing pressure sensor 402 to suspend measurement.

[0059] In an embodiment, the drainage assembly comprises a drainage main pipeline, a drainage pressure pipeline, a first drainage pressure sensor, a second drainage pressure sensor, a liquid level sensor and a negative pressure pump, a second inlet end of the drainage main pipeline and a third inlet end of the drainage pressure pipeline are used for accessing the thoracic cavity together, a second outlet end of the drainage main pipeline, the first drainage pressure sensor and the negative pressure pump are all connected with the drainage bottle, a third outlet end of the drainage pressure pipeline is connected with 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 with the host computer, and S1 specifically further comprises:

[0060] S12: acquiring real-time liquid level data of the drainage bottle from the liquid level sensor, and acquiring real-time drainage flow data according to the real-time liquid level data;

[0061] S13: acquiring real-time driving data of the negative pressure pump, 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, and acquiring real-time air leakage flow data according to the real-time drainage bottle pressure data, the real-time drainage pleural pressure data and the real-time driving 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 the existing chest drainage device, the drainage pressure pipeline 302 needs to be connected with the air release valve (not shown in the figure) in the host 200 for measuring real-time drainage pleural pressure data. To ensure safety, a one-way valve 306 needs to be arranged inside the drainage pressure pipeline 302, that is, the one-way valve 306 is an indispensable component.

[0073] Generally, the pleural pressure is negative pressure, and the one-way valve 306 is in an open state at this time. At this time, the drainage pressure pipeline 302 forms a passage with the drainage main pipeline 301 and the chest cavity. Since the pressure inside the drainage bottle 100 is lower than the pressure inside the drainage pressure pipeline 302, when the one-way valve 306 is in the open state, the chest cavity liquid will not enter the drainage pressure pipeline 302. The second drainage pressure sensor 304 can measure the real-time drainage pleural pressure data of the patient through the drainage pressure pipeline 302, and the measured real-time drainage pleural pressure data is all negative pressure. However, if the pleural pressure abnormally appears positive pressure, the one-way valve 306 will be closed. At this time, the drainage pressure pipeline 302 does not form a passage with the drainage main pipeline 301, and the liquid in the drainage main pipeline 301 and the drainage bottle 100 will be blocked by the one-way valve 306 and cannot enter the drainage pressure pipeline 302, so as to ensure the safety of the drainage pressure pipeline 302 and other components connected thereto. Therefore, by using the above structure, the second drainage pressure sensor 304 can only measure the negative pressure pleural pressure, and cannot measure the positive pressure pleural pressure. The real-time drainage pleural pressure data obtained by the host 200 from the second drainage pressure sensor 304 is always negative pressure.

[0074] From the above content, it can be seen that due to the existence of the one-way valve 306, the original drainage pressure pipeline 302 and the second drainage pressure sensor 304 in the device can only measure negative pressure. If only the breathing mode is added in the original device, the negative pressure breathing pleural pressure can also be measured by the original drainage pressure pipeline 302 and the second drainage pressure sensor 304, but the positive pressure breathing pleural pressure cannot be obtained, which will make the measured real-time drainage pleural pressure data not accurate and complete. That is, based on the hardware structure of the current chest drainage device, the positive pressure breathing pleural pressure cannot be obtained only by setting the software algorithm, and the hardware structure must be changed.

[0075] Therefore, in the embodiments of the present application, without changing the original drainage assembly 300, by adding the respiratory pressure pipeline 401 and the respiratory pressure sensor 402 in the existing chest drainage device, and without setting the one-way valve 306 inside the respiratory pressure pipeline 401, whether the pleural pressure is positive pressure or negative pressure, it can be measured by the respiratory pressure sensor 402, and accurate and complete real-time drainage pleural pressure data can be obtained, and the host 200 can obtain real-time respiratory pleural pressure data of positive pressure or negative pressure from the respiratory pressure sensor 402. Since the scheme does not need to make great changes to the structure of the existing chest drainage device, the cost is low, and the practicability is high.

[0076] The second drainage pressure sensor 304 of the chest drainage device in the prior art can only measure negative pressure, so the type is only a negative pressure sensor, and the respiratory pressure sensor 402 in the embodiments of the present application needs to measure positive pressure and negative pressure, so the type needs to be set as a positive and negative pressure sensor to meet the clinical needs.

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

[0078] S14: In the drainage mode, the isolation switch is controlled to be opened, so that a passage is formed between the drainage bottle and the respiratory pressure pipeline, and real-time drainage flow data and real-time air leakage flow data are obtained from the drainage assembly.

[0079] S15: In the breathing mode, the isolation switch is controlled to be closed, so that no passage is formed between the drainage bottle and the respiratory pressure pipeline, and real-time respiratory pleural pressure data are obtained from the breathing assembly.

[0080] Since the drainage main pipeline 301 and the respiratory pressure pipeline 401 are connected with the chest cavity, and the drainage main pipeline 301 is connected with the drainage bottle 100, a passage is formed between the drainage bottle 100 and the drainage main pipeline 301 and the respiratory pressure pipeline 401. In the breathing mode, although the drainage assembly 300 stops drainage, the above passage will cause the gas in the drainage bottle 100 and the drainage main pipeline 301 to interfere with the measurement of the respiratory pleural pressure, resulting in inaccurate measurement results.

[0081] In the embodiment of the present application, the isolation switch 307 is arranged on the drainage path of the drainage main pipe 301. When the drainage mode is entered, the host 200 controls the isolation switch 307 to open, and the above-mentioned path is maintained, which does not affect the normal drainage work of the drainage assembly 300. At this time, the real-time drainage flow data and the real-time air leakage flow data can be normally obtained from the drainage assembly 300. When the breathing mode is entered, the host 200 controls the isolation switch 307 to close, which can cut off the above-mentioned path, eliminate the above-mentioned interference, and improve the accuracy of the real-time respiratory pleural pressure data obtained by the host 200. On the premise of not affecting the normal drainage function, the isolation switch 307 can be arranged as close as possible to the second inlet end 31 of the drainage main pipe 301 to reduce the influence of the drainage main pipe 301 on the respiratory pleural pressure as much as possible. The isolation switch 307 can be an electromagnetic valve, which is arranged on the drainage path of the drainage main pipe 301 through the switch base 308. The electromagnetic valve can receive the electrical signal of the host 200 to automatically realize the opening and closing functions without manual opening and closing.

[0082] S2: Obtain continuous drainage flow data, continuous air leakage flow data and continuous respiratory pleural pressure data according to the real-time drainage flow data, the real-time air leakage flow data, the real-time respiratory pleural pressure data and the current working duration.

[0083] The real-time drainage flow data, the real-time air leakage flow data and the real-time respiratory pleural pressure data are all discrete data. The continuous drainage flow data, the continuous air leakage flow data and the continuous respiratory pleural pressure data can be obtained by collecting and classifying the discrete data at each time under the current working duration. The current working duration refers to the total duration from the starting time of the first time entering the drainage mode to the current time.

[0084] S3: Determine whether any time meets the stop working condition, and the stop working condition is that the continuous drainage flow data, the continuous air leakage flow data and the continuous respiratory pleural pressure data all meet the corresponding reference indicators.

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

[0086] The judgment can be made at any time after the device starts running in this step, but the application is not limited thereto. To reduce the amount of calculation, the judgment can also be made only once at the end of each breathing mode, and only data is monitored at other times. Those skilled in the art can choose to make the judgment at any time or only at the end time according to actual needs.

[0087] S4: If yes, a stop working prompt information is generated.

[0088] If the judgment result is yes, it indicates that the drainage effect is good, and the drainage can be stopped. At this time, the host 200 can generate a stop working prompt information, and output the information in the form of text, sound, image, etc. through the man-machine interaction device of the chest drainage device alone or in combination, so that relevant personnel can obtain the information in time and perform subsequent extubation operation according to the information.

[0089] In an embodiment, before S1, further comprising:

[0090] Sa: Obtain mode switching parameters of the drainage mode and the breathing mode.

[0091] Sb: According to the mode switching parameters, determine the switching sequence of the drainage mode and the breathing mode, and the first time length of the drainage mode and the second time length of the breathing mode, the first time length being greater than the second time length.

[0092] The mode switching parameters include the entering sequence and the entering time length of each mode, which need to be preset and stored in the host 200. Before performing step S1, the host 200 first obtains the parameters, and then determines according to the parameters that the first entering mode is the drainage mode, the drainage mode needs to last for the first time length, and the switching mode is the breathing mode, which needs to last for the second time length. After determining these information, the host 200 controls the related components in the chest drainage device to perform the first mode entering operation and mode switching operation according to the information. If the stop working condition in S3 is not met after the end of this time two modes, the host 200 will control the related components in the chest drainage device to continue to perform the second mode entering operation and mode switching operation according to the above information, and the subsequent is the same. In order to balance the better drainage efficiency and sufficient respiratory pleural pressure data, the first time length will be greater than the second time length. For example, the first time length is 5 min, and the second time length is 30 s.

[0093] In the above manner, after the mode switching parameters are set, the chest drainage device can automatically complete each mode entering operation and mode switching operation, without the need for manual participation, and the efficiency is high.

[0094] In an embodiment, after S4, further comprising:

[0095] S5: If no, judge whether the current moment continuous respiratory pleural pressure data meets the corresponding reference index.

[0096] S6: If yes, lengthen the first time length or shorten the second time length to obtain updated mode switching parameters.

[0097] If the judgment result in S3 is no, it means that at least one of the above three types of data does not meet the corresponding reference index. At this time, it can be judged which one does not meet the condition. If the current moment continuous respiratory pleural pressure data meets the corresponding reference index, but other types of data do not meet the corresponding reference index, it means that the demand for drainage is more urgent at this moment relative to the acquisition of real-time respiratory pleural pressure data, or in other words, based on the current moment continuous respiratory pleural pressure data, it can be represented that the respiratory pleural pressure is not abnormal, and the drainage process can be accelerated to achieve early extubation. Therefore, for this kind of situation, the host 200 can lengthen the first time length, for example, 5 min to 8 min, or shorten the second time length, for example, 30 s to 15 s, and use the lengthened first time length or shortened second time length to update the initially set mode switching parameters. In the next execution of the mode entering operation and the mode switching operation, the host 200 controls the relevant components to operate based on the updated mode switching operation.

[0098] In the above manner, the host 200 can automatically accelerate the drainage process according to the actual situation, thereby improving the work efficiency.

[0099] As shown in FIG. 2, it is a second flowchart of the thoracic cavity data monitoring method provided by the embodiment of the present application, and the working process of the above embodiment will be described as a whole. Figure 4 Figure 4

[0100] ​​At the beginning, the host 200 first initializes the drainage flow data, the air leakage flow data and the respiratory pleural pressure data, and then enters the drainage mode based on the preset mode switching parameter, at this time, the isolation switch 307 is in the open state, so as to form a path between the drainage bottle 100 and the chest cavity, and the host 200 controls the drainage assembly 300 to obtain real-time drainage flow data and real-time air leakage flow data. The host 200 judges whether the switching time of the respiratory mode is reached based on the mode switching parameter, if the judgment result is no, the real-time drainage flow data and the real-time air leakage flow data are continuously monitored, if the judgment result is yes, the host 200 controls the drainage assembly 300 to suspend the drainage, and enters the respiratory mode, at this time, the isolation switch 307 is in the closed state, so as to form no path between the drainage bottle 100 and the respiratory assembly 400, the host 200 controls the respiratory assembly 400 to obtain real-time respiratory pleural pressure data, and judges whether the stop working condition is met, the stop working condition is that the continuous drainage flow data, the continuous air leakage flow data and the continuous respiratory pleural pressure data under the current working time length all meet the respective reference indexes. If the judgment result is no, the drainage mode is entered again, and the above steps are executed circularly, if the judgment result is yes, a stop working prompt information is generated, and the information is output through the human-computer interaction device, and the process is ended. The relevant personnel can obtain the information in time, and perform subsequent extubation operation according to the information.

[0101] It can be known from the above embodiment that the chest cavity data monitoring method provided by the application sets the drainage mode and the respiratory mode which are alternately performed in the chest drainage device, and adds the respiratory assembly, the original drainage assembly performs drainage in the drainage mode and suspends the drainage in the respiratory mode, the added respiratory assembly performs respiratory pleural pressure monitoring in the respiratory mode, the host first obtains real-time drainage flow data and real-time air leakage flow data from the drainage assembly in the drainage mode, and obtains real-time respiratory pleural pressure data from the respiratory assembly in the respiratory mode, then according to the real-time drainage flow data, the real-time air leakage flow data, the real-time respiratory pleural pressure data and the current working time length, the continuous drainage flow data, the continuous air leakage flow data and the continuous respiratory pleural pressure data are obtained, whether the stop working condition is met at any time is judged, the stop working condition is that the continuous drainage flow data, the continuous air leakage flow data and the continuous respiratory pleural pressure data all meet the corresponding reference indexes, if yes, a stop working prompt information is generated. The application determines that the chest cavity drainage device needs to stop working only when the continuous drainage flow data, the continuous air leakage flow data and the continuous respiratory pleural pressure data all meet the reference indexes, and the determination is based on the continuous respiratory pleural pressure data rather than discrete data, so that secondary drainage is not needed, that is, the determination of the working stop time of the chest cavity drainage device is more accurate.
