Description

TECHNICAL FIELD

[0001] The present application relates to the medical technical field, and in particular to a chest drainage flow data display method and device, electronic equipment and storage medium. BACKGROUND

[0002] Monitoring the drainage flow of the drainage liquid by a digital chest drainage device has very important clinical significance in the treatment process, and can provide quantitative basis for the judgment of the extubation opportunity. When monitoring the drainage flow, the liquid level sensor is first used to measure the liquid level height in the drainage bottle, and then the drainage flow data is calculated and displayed on the display screen of the chest drainage device.

[0003] There are various schemes in the prior art for measuring the liquid level height by the liquid level sensor. For example, patent CN102121844B discloses that a plurality of giant magnetoresistance sensors are arranged on one side of the container, and a magnetic floating ball is arranged in the container. The liquid level height in the container is obtained by calculating the position of the magnetic floating ball by the giant magnetoresistance sensor. This scheme is used to measure the horizontal liquid level height. When it is necessary to measure the liquid level height of the inclined liquid surface placed in the horizontal state (hereinafter referred to as the inclined liquid level height), the prior art usually combines an inclination sensor to first measure the inclination angle, and then calculates the inclined liquid level height according to the inclination angle and the magnetic ball height. However, due to the data feedback delay and insufficient accuracy of the inclination sensor itself, the calculated inclined liquid level height is not accurate enough. To solve this problem, patent CN105004402B discloses that three ultrasonic sensors are arranged above the container. The liquid level of three different points of the inclined liquid surface is first calculated by the three ultrasonic sensors, and the inclination angle is calculated based on this. Finally, the inclined liquid level height is calculated. This scheme cancels the inclination sensor and uses the ultrasonic sensor itself to obtain the inclination angle, so that the accuracy is improved to a certain extent.

[0004] However, the above schemes calculate the inclined liquid level according to the inclined liquid surface as a flat inclined surface, and the digitalized chest drainage device is a portable device. If the patient moves during use, the liquid in the drainage bottle will shake. From the start of the shaking to the end of the shaking, the entire liquid surface does not directly transition from a flat horizontal surface to a flat inclined surface, but will produce irregular fluctuations. Therefore, the liquid surface is not always flat in the shaking state, and the more severe the shaking, the more uneven the liquid surface. When the liquid is in a shaking state, if the digitalized chest drainage device adopts the scheme in patent CN102121844B, the magnetic floating ball will be offset in the liquid due to the influence of shaking, which will cause inaccurate calculation of the position of the magnetic ball, and further cause large errors in the calculation of the inclined liquid level, which is not the true liquid level. If the digitalized chest drainage device adopts the scheme in patent CN105004402B, the inclined liquid level calculated based on the liquid level of three points still has a large error due to the uneven liquid surface in the shaking state. Therefore, when the liquid in the drainage bottle is in a shaking state, the above errors will cause the measured inclined liquid level to change frequently, and further cause the drainage volume displayed on the display screen of the chest drainage device to also fluctuate frequently, which is unstable. In fact, the drainage volume does not change much, which makes it difficult for the patient or medical staff to obtain data of reference value.

[0005] Therefore, the current chest drainage device has the technical problem of inaccurate display of drainage volume data, which needs to be improved. SUMMARY

[0048] Beneficial Effects: This application provides a method, device, electronic device, and storage medium for displaying chest drainage volume data. The method involves setting magnetoresistive sensor groups on opposite sides of the drainage bottle. The height data of the magnetic float is acquired using these two magnetoresistive sensor groups, and the tilt angle is calculated accordingly. When the tilt angle is not greater than a preset angle, it is determined that the drainage bottle is not in a state of violent shaking. The chest drainage volume data for each moment is directly calculated based on the height data groups and displayed at a first frequency, ensuring the accuracy and timeliness of the chest drainage volume data display.

In this case, n consecutive height data groups are first taken, and then m target height data groups are selected from them. The chest drainage volume data is calculated based on these and displayed at a second frequency. Since the second frequency is equal to 1 / n of the first frequency, it can solve the calculation error caused by the shaking of single-point values ​​and alleviate the display fluctuations caused by frequent changes in drainage volume data. The combination of these two factors makes the display of chest drainage volume data more accurate. Attached Figure Description

Detailed Implementation

[0058] 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.

[0059] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating a scenario in which the method for displaying chest drainage volume data provided in this application embodiment is applied. This scenario includes a chest drainage device. Figure 2 and Figure 3 These are the top and front views of a chest drainage device, respectively. Figures 1 to 3It is known that the chest drainage device includes a main unit 11 and a drainage bottle 12. The drainage bottle 12 is detachably connected to the main unit 11. The drainage bottle 12 includes a first side 121 and a second side 122 arranged opposite to each other. In the connection area between the two, a first magnetoresistive sensor group and a second magnetoresistive sensor group are respectively arranged on the outside of the first side 121 and the outside of the second side 122. The first magnetoresistive sensor group includes a first upper magnetoresistive sensor 1 arranged at the top and a first lower magnetoresistive sensor 2 arranged at the bottom. The second magnetoresistive sensor group includes a second upper magnetoresistive sensor 3 arranged at the top and a second lower magnetoresistive sensor 4 arranged at the bottom. A first float channel 7 and a second float channel 8 extending along the height direction of the drainage bottle 12 are respectively arranged inside the first side 121 and the second side 122. A first magnetic float 5 is arranged in the first float channel 7 and a second magnetic float 6 is arranged in the second float channel 8.

[0060] The host 11 obtains the first height data of the first magnetic float 5 and the second height data of the second magnetic float 6 through the first magnetoresistive sensor group and the second magnetoresistive sensor group, respectively, to obtain the height data group at each moment. The tilt angle is calculated based on this data. When the tilt angle is not greater than the preset angle, it is determined that the drainage bottle 12 has not entered a violent shaking state. The chest drainage volume data at each moment is directly calculated based on the height data group at each moment and displayed on the display screen 111 of the host 11 at the first frequency. This ensures the accuracy and timeliness of the chest drainage volume data display. When the tilt angle is greater than the preset angle, it is determined that the drainage bottle 12 has entered a violent shaking state. At this time, the height data group at n consecutive moments is taken first, and then m target height data groups are selected from them. The chest drainage volume data is calculated based on this data and displayed on the display screen 111 of the host 11 at the second frequency.

[0061] Since the second frequency is equal to 1 / n of the first frequency, it can both resolve the calculation error caused by the shaking of single-point values ​​and alleviate the display fluctuations caused by frequent changes in drainage volume data. The combination of these two factors makes the display of chest drainage volume data more accurate. In the following embodiments, the process of displaying chest drainage volume data will be described in detail in conjunction with the above structure.

[0062] Please see Figure 4 , Figure 4 This is a flowchart illustrating a method for displaying chest drainage data provided in an embodiment of this application. The method specifically includes:

[0063] S1: The first height data of the first magnetic buoy at each time moment is obtained by the first magnetoresistive sensor group at the first frequency, and the second height data of the second magnetic buoy at each time moment is obtained by the second magnetoresistive sensor group at the first frequency, so as to obtain the height data group at each time moment.

[0064] Combination Figures 1 to 3As shown, the drainage bottle 12 is connected to the human chest cavity via a drainage tube. Under the control of the main unit 11, the drainage fluid in the chest cavity can flow into the drainage bottle 12. As drainage proceeds, the fluid level gradually rises. The first magnetic float 5 and the second magnetic float 6, installed in the first float channel 7 and the second float channel 8, also rise with the fluid level. The dotted line between the first magnetic float 5 and the second magnetic float 6 indicates an inclined fluid surface. The first float channel 7 and the second float channel 8 can confine the first magnetic float 5 and the second magnetic float 6 within the channel, but drainage fluid from other areas can freely enter and exit the first float channel 7 and the second float channel 8. Therefore, the fluid levels inside and outside the two channels can be kept basically level. The height of the first magnetic float 5 and the second magnetic float 6 can be used to determine the fluid level at the location of the float.

[0065] Each magnetoresistive sensor operates based on the magnetoresistance effect, which refers to the change in resistivity of a magnetic material when placed in an external magnetic field. Specifically, each magnetoresistive sensor contains a sensing element, and each magnetic float provides the external magnetic field. When the sensing element is affected by the external magnetic field, its resistance changes. By measuring this change in resistance, the change in magnetic field can be determined. Since the change in magnetic field is related to the change in distance between the sensing element and the magnetic float, the data measured by each magnetoresistive sensor can be converted from digital to analog, outputting an AD value. This AD value is then used to obtain the distance data between the two elements, and thus the height data of each magnetic float.

[0066] In this embodiment, the first height data of the first magnetic float 5 can be obtained through the magnetoresistive effect between the first magnetoresistive sensor group and the first magnetic float 5, and the second height data of the second magnetic float 6 can be obtained through the magnetoresistive effect between the second magnetoresistive sensor group and the second magnetic float 6. The first height data and the second height data obtained at the same time constitute the height data set at that time. When acquiring the first height data and the second height data, a first frequency is used. The value of the first frequency can be set as needed. For example, a first frequency of 10Hz means that data from 10 moments are acquired per second, and the interval between any two adjacent moments in the 10 moments is equal. For ease of explanation, in the following embodiments, Hl and Hr are used to represent the first height data and the second height data, respectively.

[0067] In one embodiment, S1 specifically includes:

[0068] S11: When the drainage flow is zero, the first minimum magnetic signal data and the first maximum magnetic signal data of the first magnetic float are obtained by the first upper magnetoresistive sensor and the first lower magnetoresistive sensor, respectively. The second minimum magnetic signal data and the second maximum magnetic signal data of the second magnetic float are obtained by the second upper magnetoresistive sensor and the second lower magnetoresistive sensor, respectively.

[0069] The magnetic signal data measured by the magnetoresistive sensor is negatively correlated with the distance between the magnetoresistive sensor and the magnetic float; that is, the closer the distance, the stronger the magnetic signal. Initially, there is no drainage fluid in the drainage bottle 12, and the drainage flow is zero. At this time, the first magnetic float 5 is located at the bottom of the first float channel 7. The first upper magnetoresistive sensor 1 can acquire the first minimum magnetic signal data Vmin1 related to the first magnetic float 5, and the first lower magnetoresistive sensor 2 can acquire the first maximum magnetic signal data Vmax1 related to the first magnetic float 5. Similarly, the second upper magnetoresistive sensor 3 can acquire the second minimum magnetic signal data Vmin2 related to the second magnetic float 6, and the second lower magnetoresistive sensor 4 can acquire the second maximum magnetic signal data Vmax2 related to the second magnetic float 6.

[0070] S12: When the flow rate is not zero, the first magnetic signal data of the first magnetic float at each time is obtained through the first upper magnetoresistive sensor, and the second magnetic signal data of the second magnetic float at each time is obtained through the second upper magnetoresistive sensor.

[0071] At other times after the drainage begins, the drainage volume is not zero. At this time, the first magnetic float 5 is located between the top and bottom of the first float channel 7. The first magnetic signal data Va1 of the first magnetic float 5 can be obtained through the first upper magnetoresistive sensor 1, and the second magnetic signal data Va2 of the second magnetic float 6 can be obtained through the second upper magnetoresistive sensor 3.

[0072] S13: Based on the first minimum magnetic signal data, the first maximum magnetic signal data, the first magnetic signal data, and the maximum height data of the drainage bottle, obtain the first height data of the first magnetic float at each time point.

[0073] In existing technology, a single magnetoresistive sensor is used to directly measure the magnetic signal between itself and a magnetic float. The height of the magnetic float is then calculated from the magnetic signal, and this data is used as the liquid level height at the location of the magnetic float. However, zero-point offset of the magnetoresistive sensor can lead to inaccurate liquid level monitoring. For example, when the drainage flow is zero, the actual liquid level height at the location of the magnetic float is also zero, but the magnetoresistive sensor may measure a non-zero value, resulting in errors in all subsequent height measurements, and thus a relatively large error in the liquid level height.

[0074] In this embodiment of the application, after obtaining the above data, relevant calculations are performed on the data at each time to remove the influence caused by the zero-point offset of the first magnetoresistive sensor group. The first height data Hl of the first magnetic float 5 can reflect the true liquid level height at that position.

[0075] S14: Based on the second minimum magnetic signal data, the second maximum magnetic signal data, the second magnetic signal data, and the maximum height data of the drainage bottle, obtain the second height data of the second magnetic float at each time point.

[0076] Similarly, after obtaining the above data, relevant calculations are performed on the data at each time point to remove the influence caused by the zero-point offset of the second magnetoresistive sensor group. The resulting second height data Hr of the second magnetic float 6 can reflect the true liquid level height at that position.

[0077] S15: Combine the first altitude data and the second altitude data at each time point to obtain the altitude data set at each time point.

[0078] By combining the first altitude data Hl and the second altitude data Hr at each time point, the altitude data set at each time point can be obtained.

[0079] In one embodiment, S14 specifically includes:

[0080] S141: Calculate the first difference between the first maximum magnetic signal data and the first minimum magnetic signal data at each time point, and the second difference between the first magnetic signal data and the first minimum magnetic signal data.

[0081] S142: Calculate the first ratio of the first difference and the second difference at each time point, and calculate the first product of the first ratio and the maximum height data of the drainage bottle at each time point.

[0082] S143: Determine the first product at each time point as the first height data of the first magnetic buoy at each time point.

[0083] The first difference Va1-Vmin1 represents the change in magnetic signal data measured by the first upper magnetoresistive sensor 1 from the moment when the drainage volume is zero to any moment when the drainage volume is not zero. The second difference Vmax1-Vmin1 represents the range of magnetic signal data that can be measured within the capability range of the first magnetoresistive sensor group. The first ratio of the two is (Va1-Vmin1) / (Vmax1-Vmin1), which represents the proportion of the change in magnetic signal data corresponding to the first magnetic float 5 within the entire magnetic signal data range. Since the magnetic signal data corresponds one-to-one with the height data, this ratio can be used to represent the proportion of the change in the height of the first magnetic float 5 within the entire height range. Multiplying this proportion by the maximum height data Hmax of the drainage bottle 12, the first product is determined as the first height data Hl of the first magnetic float 5. This process can be expressed by the following formula:

[0084] (Formula 1)

[0085] In one embodiment, S15 specifically includes:

[0086] S151: Calculate the third difference between the second maximum magnetic signal data and the second minimum magnetic signal data at each time point, and the fourth difference between the second magnetic signal data and the second minimum magnetic signal data.

[0087] S152: Calculate the second ratio of the third and fourth differences at each time point, and calculate the second product of the second ratio and the maximum height data of the drainage bottle at each time point.

[0088] S153: Determine the second product at each time point as the second height data of the second magnetic buoy at each time point.

[0089] Similarly, the third difference Va2-Vmin2 represents the change in magnetic signal data measured by the first upper magnetoresistive sensor 1 from the moment when the drainage volume is zero to any moment when the drainage volume is not zero. The fourth difference Vmax2-Vmin2 represents the range of magnetic signal data that can be measured within the capability range of the second magnetoresistive sensor group. The second ratio of the two is (Va2-Vmin2) / (Vmax2-Vmin2), which represents the proportion of the change in magnetic signal data corresponding to the second magnetic float 6 within the entire magnetic signal data range. Since the magnetic signal data corresponds one-to-one with the height data, this ratio can be used to represent the proportion of the change in the height of the second magnetic float 6 within the entire height range. Multiplying this proportion by the maximum height data Hmax of the drainage bottle 12, the resulting second product is determined as the second height data Hr of the second magnetic float 6. This process can be expressed by the following formula:

[0090] (Formula 2)

[0091] Since the percentage of height variation within the entire height range is not affected by whether the magnetic sensor has zero-position offset, the calculated percentage is very accurate. The maximum height data Hmax of the drainage bottle 12 is a pre-designed fixed value. Therefore, the first height data Hl and the second height data Hr obtained based on the above two formulas can eliminate the influence of zero-position offset and have high accuracy.

[0092] S2: Based on the width data of the drainage bottle and the height data at each time point, obtain the tilt angle of the drainage bottle at each time point.

[0093] Let the width of the drainage bottle 12 be W, and the height data set at a certain moment include the first height data Hl and the second height data Hr. Then, the tilt angle θ of the drainage bottle 12 at that moment satisfies the following formula:

[0094] (Formula 3)

[0095] According to this formula, the tilt angle at each moment under the first frequency can be calculated, and this value is also the tilt angle of the liquid surface at each moment.

[0096] S3: Determine whether the tilt angle at the current moment is greater than the preset angle.

[0097] The current time can be any time at the first frequency. After calculating the tilt angle at the current time, first determine whether its value is greater than the preset angle. The value of the preset angle can be set based on experience, such as 15 degrees. The standard for setting this value is: when it exceeds this angle, the liquid surface will shake more violently, and vice versa.

[0098] S4: If not, obtain the center liquid level height data of the drainage bottle based on the average height of the height data group at the current moment. Based on the center liquid level height data, the maximum height data of the drainage bottle, and the maximum capacity data of the drainage bottle, obtain the chest drainage volume data and display it in the host at the first frequency.

[0099] If the judgment result is negative, it means that the liquid surface is not sloshing at the current moment, the liquid surface is a flat horizontal surface, or the sloshing amplitude is small, and the liquid surface can maintain a roughly flat inclined surface during sloshing and can quickly return to a flat horizontal surface. In this case, the average of the first height data Hl and the second height data Hr contained in the current height data group can be directly calculated, and the calculated average height is taken as the center liquid level height of the drainage bottle. This value can characterize the liquid level height after the inclined liquid surface is leveled. Let the center liquid level height be Hm, then Hm satisfies the following formula:

[0100] (Formula 4)

[0101] Let Hmax be the maximum height of the drainage bottle and Vmax be the maximum volume of the drainage bottle. Then, what is the chest drainage volume at the current moment? Satisfy the following formula:

[0102] (Formula 5)

[0103] In obtaining Then, it is displayed in the host at the first frequency, that is, every time a moment is calculated. All of these are refreshed and displayed on the display screen 111 of the host 11.

[0104] S5: If so, acquire n height data sets at n consecutive time points, determine m target height data sets from the n height data sets, obtain the center liquid level height data of the drainage bottle based on the average height of the m target height data sets, obtain the chest cavity drainage volume data based on the center liquid level height data, the maximum height data of the drainage bottle, and the maximum capacity data of the drainage bottle, and display it in the host at a second frequency. The second frequency is equal to 1 / n of the first frequency, where m and n are both integers greater than 1, and m is not greater than n.

[0105] If the judgment result is yes, it indicates that the current tilt is too large, and the liquid surface will enter a state of violent shaking. The center liquid level height Hm is calculated using only the first height data Hl and the second height data Hr measured at a single point, and then the result is obtained. There will be a large error, and this error will cause [the problem] at different times under the first frequency. The values ​​change frequently, and if they are still displayed at the highest frequency, it will cause the displayed data to fluctuate significantly.

[0106] Therefore, in this embodiment, if the judgment result is yes, then n consecutive height data groups at n consecutive moments will be acquired first. The n consecutive moments refer to n moments at the first frequency. During acquisition, a first data queue can be established for the first height data. Initially, the data insertion pointer points to 0. Each time a first height data is acquired from the first magnetoresistive sensor group, it is placed sequentially into the first data queue, and the data insertion pointer is moved one position to the right. When the total number of data in the first data queue is n, it can be taken out as n height data groups, and the data insertion pointer in the first data queue is reset to 0. The process continues to acquire the next n consecutive height data groups. The same applies to the second height data, and will not be elaborated further here. After acquiring n height data groups, m target height data groups that meet the requirements can be selected from them, where m and n are both integers greater than 1, and m is not greater than n.

[0107] When m equals n, it means that all n altitude data sets meet the requirements. In this case, the mean of the m first altitude data Hl is calculated respectively. The mean of m second altitude data Hr Finally, the calculation was completed. and The average height of the accumulator is taken as the center liquid level height of the drainage bottle. This value can characterize the liquid level height after the tilted liquid surface is leveled. Let the center liquid level height be... ,but Satisfy the following formula:

[0108] (Formula 6)

[0109] Let Hmax be the maximum height of the drainage bottle and Vmax be the maximum capacity of the drainage bottle, then the chest drainage volume data... Satisfy the following formula:

[0110] (Formula 7)

[0111] because The data is calculated based on n height data groups, and then it is displayed in the host at a second frequency. The second frequency is equal to 1 / n of the first frequency. If the first frequency is 10Hz and n is 10, then the second frequency is 1Hz, which means that it is displayed once every 1 second from the current moment.

[0112] In this step, when the drainage bottle 12 is shaken violently, the average of the height data at multiple moments is taken to calculate the final chest drainage volume data, which plays a role in smoothing and filtering. Compared with the single-point value and calculation scheme, the calculation result in this application is more accurate and has less error. In addition, this application uses a lower second frequency to display the data, which will reduce the display jitter problem caused by the above-mentioned error. The displayed chest drainage volume data can provide effective reference value for patients or medical staff.

[0113] There are multiple ways to obtain n sets of height data at n consecutive time points.

[0114] In one embodiment, S5 specifically includes:

[0115] S51: Obtain the altitude data sets for n consecutive time intervals starting from the current time, resulting in n altitude data sets.

[0116] In this embodiment, starting from the current time t1, n sets of height data are acquired sequentially from t1, resulting in a total of n sets of height data. This set of data can reflect the overall change of the liquid level from the current time onwards.

[0117] In another embodiment, S5 specifically includes:

[0118] S52: Obtain the altitude data sets for n1 consecutive moments before the current moment and the altitude data sets for n2 consecutive moments from the current moment, to obtain n altitude data sets, n1+n2=n.

[0119] In this embodiment, taking the current time t1 as the intermediate time, n1 consecutive time intervals before t1 are acquired, and n2 time intervals are acquired sequentially starting from t1, resulting in a total of n time intervals. Typically, the swaying state does not last long; therefore, the change in liquid level height from slight to significant swaying is not substantial. Since the calculated liquid level height before t1 is more accurate than under swaying conditions, using n1 time intervals of height data from before t1 for calculation can reduce the error caused by swaying, resulting in more accurate results.

[0120] The above steps S51 and S52 are parallel technical solutions. Those skilled in the art can choose one of the solutions to perform as needed to achieve the desired effect.

[0121] When m is less than n, it means that only a portion of the n height data groups meet the requirements, and further filtering is needed. Therefore, in one embodiment, the following is included after S51 or S52:

[0122] S53: Determine whether there is a non-target height data group among the n height data groups, and whether the tilt angle corresponding to the non-target height data group is equal to that of any other height data group.

[0123] S54: If so, remove the non-target height data groups from the n height data groups, and determine the remaining height data groups as m target height data groups.

[0124] Normally, when the liquid surface shakes violently, the highest and lowest points will alternately appear at the positions of the first magnetic float 5 and the second magnetic float 6. During this alternation, there will be instances where the left and right tilt angles are equal. For example, at a certain moment, the position of the first magnetic float 5 is lower than the position of the second magnetic float 6, with a left tilt angle of 16 degrees. As the shaking continues, the position of the first magnetic float 5 continues to descend, while the position of the second magnetic float 6 continues to rise, reaching a maximum left tilt angle of 17 degrees. Subsequently, the position of the first magnetic float 5 gradually rises, while the position of the second magnetic float 6 gradually descends until the position of the first magnetic float 5 is higher than the position of the second magnetic float 6, with a right tilt angle of 16 degrees. If the value of n is large, or if the maximum tilt angle is close to the preset angle, then two height data sets may have tilt angles that are equal (in opposite directions). The height data contained in the two height data sets will be quite similar. If the error of one is large, the error of the other will also be large. Including both in the calculation of the average will cause the error to accumulate doubly, resulting in the final value being... The error is also relatively large.

[0125] Therefore, in this embodiment, after obtaining n height data groups, it is first determined whether there are any non-target height data groups. A non-target height data group has the same tilt angle as any other height data group. If such a group exists, it is removed, and the remaining n-1 height data groups are used as m target height data groups. This method ensures that the tilt angles corresponding to the m target height data groups are all unequal, thus avoiding the accumulation of doubled errors and improving calculation accuracy. The accuracy.

[0126] In another embodiment, following S51 or S52, the following is further included:

[0127] S55: Get the current diversion rate at the current moment.

[0128] S56: Based on the current drainage rate and real-time sloshing time, determine the reference center liquid level height range for each of the n consecutive time moments.

[0129] S57: Determine whether there is a non-target height mean among the n height mean values ​​corresponding to the n height data groups. The non-target height mean value does not fall within the reference center liquid level height range at the corresponding time.

[0130] S58: If so, remove the height data group corresponding to the non-target height average from the n height data groups, and determine the remaining height data groups as m target height data groups.

[0131] Since the shaking time usually does not last very long, the drainage volume of fluid from the pleural cavity will not change significantly during the shaking period, and the corresponding central fluid level will not change significantly either. If the central fluid level calculated at a certain moment changes significantly, the data at that moment may have a large error and needs to be removed to reduce the error of the final calculation result.

[0132] When determining these data with large errors, it is necessary to first obtain the current drainage rate at the current moment. Then, for all other moments from the current moment, the current drainage rate is used as a reference. For each moment, the reference center liquid level height range corresponding to each moment can be calculated based on the current drainage rate and the real-time agitation time. Here, the real-time agitation time refers to the difference between the agitation moment and the current moment. Specifically, assuming the current drainage rate is v, and the real-time agitation time from the current moment t1 to the next moment t2 is t2-t1, then the increase in drainage volume during this time is v*(t2-t1). Based on this value, the center liquid level height data at the current moment, and the width data of the drainage bottle, the reference center liquid level height corresponding to the next moment t2 can be calculated. Considering errors and fluctuations, the reference center liquid level height ±x% can be used as the reference center liquid level height range. The value of x% can be set as needed, for example, 5%. For moment t3 after moment t2, a reference center liquid level height range can also be obtained in the same way, and so on for other moments.

[0133] Having obtained n height data sets, for each set, calculate the average height of its first and second height data. Then, determine whether this average height falls within the reference center liquid level height range at that moment. If it does, the set is retained; otherwise, it is treated as a non-target height data set and removed from the n height data sets. The remaining height data sets are then identified as m target height data sets.

[0134] Using the above method, non-target altitude data groups with obvious errors or large errors can be removed from n altitude data groups, improving efficiency. The accuracy.

[0135] Steps S53 to S54 and S55 to S58 above are two technical solutions. Those skilled in the art can choose one of the solutions for screening as needed, or they can combine the two solutions for screening to achieve the desired effect.

[0136] As can be seen from the above embodiments, the method for displaying chest drainage volume data provided in this application sets magnetoresistive sensor groups on both opposite sides of the drainage bottle. The height data of the magnetic float is obtained through the two magnetoresistive sensor groups, and the tilt angle is calculated based on this. When the tilt angle is not greater than a preset angle, it is determined that the drainage bottle has not entered a state of violent shaking. The chest drainage volume data at each moment is directly calculated based on the height data group at each moment and displayed at a first frequency, which can ensure the accuracy and timeliness of the chest drainage volume data display. When the tilt angle is greater than the preset angle, it is determined that the drainage bottle has entered a state of violent shaking. At this time, n consecutive height data groups are first taken, and then m target height data groups are selected from them. The chest drainage volume data is calculated based on these and displayed at a second frequency. Since the second frequency is equal to 1 / n of the first frequency, it can solve the calculation error caused by the shaking of single-point values ​​and alleviate the display jump caused by frequent changes in drainage volume data. The combination of the two makes the display of chest drainage volume data more accurate.

[0137] Based on the method described in the above embodiments, this embodiment will further describe the method from the perspective of a display device for chest drainage volume data. This device is suitable for chest drainage equipment, which includes a main unit and a drainage bottle. The drainage bottle is detachably connected to the main unit.

[0169] Unlike existing technologies, the chest drainage data display device provided in this application has magnetoresistive sensor groups on both opposite sides of the drainage bottle. These two groups acquire height data of the magnetic float and use this data to calculate the tilt angle. When the tilt angle is no greater than a preset angle, the drainage bottle is determined not to be in a state of violent shaking. The chest drainage data for each moment is directly calculated based on the height data and displayed at a first frequency, ensuring the accuracy and timeliness of the chest drainage data display. When the tilt angle is greater than the preset angle, the drainage bottle is determined to be in a state of violent shaking. In this case, n consecutive height data sets are first taken, and then m target height data sets are selected from these. The chest drainage data is calculated based on these and displayed at a second frequency. Since the second frequency is equal to 1 / n of the first frequency, it can solve the calculation error caused by the shaking of single-point values ​​and alleviate the display fluctuations caused by frequent changes in drainage data. The combination of these two factors makes the display of chest drainage data more accurate.
