[0025] The present application is further described in detail below with reference to the accompanying drawings.

[0026] The present application embodiment discloses a capsule-type wireless bladder pressure detection device. Figures 1 to 3 The capsule-type wireless bladder pressure detection device includes a capsule-type detector 1 for detecting the pressure in the bladder, an abdominal wall magnetic device 2 for fixing the position of the capsule-type detector 1, and a carrying and storage-type urinary catheter 3 for placing the capsule-type detector 1 into the body.

[0027] Reference Figure 1 、 Figure 2 and Figure 5The capsule detector 1 primarily comprises a waterproof, capsule-shaped housing 11 for enclosing the internal components. Mounted within the waterproof housing are a pressure sensor 12, a wireless signal transceiver 13, a battery 14, a magnetic device 15, and a controller 16. A mounting block 17 is also provided. Battery 14 is mounted within mounting block 17 to power the pressure sensor 12, wireless signal transceiver 13, and controller 16. The pressure sensor 12, wireless signal transceiver 13, and magnetic device 15 are mounted on the outside of mounting block 17. The pressure sensor 12, wireless signal transceiver 13, and magnetic device 15 are all electrically connected to the controller 16. It should be noted that during use, due to the small size of the capsule detector 1 and its uncontrolled orientation after entry into the body, as well as factors such as malfunctions, the pressure sensor 12 may be positioned close to the bladder wall or may detect irregularities. Therefore, at least two pressure sensors 12 are provided to provide fault tolerance for subsequent pressure acquisition and ensure the accuracy of bladder pressure detection. During detection, the controller 16 controls the wireless signal transceiver 13 to send the bladder pressure detected by the pressure sensor 12 to an external control center.

[0028] Reference Figure 3 The abdominal wall magnetic device 2 includes a front covering piece 21 and a rear covering piece 22 and a central magnet 23 located between the two covering pieces. A placement groove is provided on the side of the front covering piece 21 and the rear covering piece 22 close to the magnet. When the front covering piece 21 and the rear covering piece 22 are in contact with each other, the central magnet 23 is located in the cavity between the two placement grooves. When in use, the abdominal wall magnetic device 2 is placed on the abdomen of the target user, and the position of the capsule detector 1 in the bladder is controlled by the magnetic force of the central magnet 23 and the magnetic device 15. Since the size of the capsule detector 1 is small, the position of the capsule detector 1 is fixed by magnetic force, which can prevent the capsule detector 1 from being discharged from the body during urination. When pressure testing is not required, the abdominal wall magnetic device 2 is removed from the abdomen of the target patient, and the capsule detector 1 will be discharged from the body during urination. It should be noted that the abdominal wall magnetic device 2 can be fixed to the abdomen of the target user in any form, such as by pasting, strapping, etc., and the specific fixing method is not limited here.

[0029] Reference Figure 4The transport-warehouse-type urinary catheter 3 includes a cylindrical urinary catheter body 31, and a storage cabin 32 and a storage cabin cover 33 are provided at one end of the urinary catheter body 31. The storage cabin cover 33 and the storage cabin cover 33 are streamlined, so as to facilitate the operation of entering the body. An operating handle 34 is provided at the end of the urinary catheter body 31 away from the storage cabin 32. When in use, the capsule detector 1 is placed in the storage cabin 32 and the storage cabin cover 33 is closed. After the transport-warehouse-type urinary catheter 3 enters the body, the storage cabin cover 33 is controlled to open by the operating handle 34, and the capsule detector 1 falls from the storage cabin 32 into the bladder. The storage cabin cover 33 is then controlled to close by the operating handle 34 to take the transport-warehouse-type urinary catheter 3 out of the body, and the placement of the capsule detector 1 is completed.

[0030] The present invention provides a capsule-based wireless bladder pressure detection method. This method can be performed by an electronic device, which can be a server or a terminal device. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be, but is not limited to, a smartphone, tablet computer, or desktop computer.

[0031] Figure 6 A flowchart of a capsule-type wireless bladder pressure detection method provided in an embodiment of the present application.

[0032] like Figure 6 As shown, the main process of the method is described as follows (steps S101 to S107): Step S101 : acquiring bladder pressure data collected by a pressure sensor, pressure collection information corresponding to the bladder pressure data, and historical pressure information of a target user.

[0033] In this embodiment, each pressure sensor is associated with its own collected bladder pressure value and corresponding pressure collection information. After obtaining the bladder pressure value and unique corresponding pressure collection information sent by each pressure sensor, all bladder pressure values ​​are labeled and aggregated according to the preset sensor number to obtain bladder pressure data. Specifically, the bladder pressure data is the bladder pressure value collected at each pressure collection time point during the entire pressure collection cycle. Each bladder pressure value is associated with corresponding pressure collection information. The pressure collection information includes the pressure collection time, the corresponding pressure sensor number, and the pressure collection duration. The target user's historical pressure information includes historical pressure collection time points and the historical bladder pressure values ​​corresponding to each historical pressure collection time point. The historical bladder pressure values ​​are standard data obtained without using a capsule detector. The historical pressure information is data collected within a recent period, such as the past 24 hours or the past 48 hours. The collection time should not be too early; it should be data collected under conditions similar to the current situation and can be used as a reference. It should be noted that the specific pressure collection information and historical pressure information need to be added according to actual needs and are not specifically limited here.

[0034] Step S102: determining the standard bladder data of the target user based on the historical pressure information.

[0035] For step S102, the target user's historical drinking information and historical urination information are obtained; the peak and valley values ​​of the bladder pressure are determined based on the historical drinking information, historical urination information, and historical pressure information; a pressure change report is generated based on the historical drinking information, historical urination information, historical pressure information, and the pressure peak and valley values; the target user's pressure change pattern is determined based on the pressure change report; and the pressure change pattern is used as standard bladder data.

[0036] In this embodiment, the target user's historical drinking information and historical urination information are information corresponding to the historical pressure information, that is, the target user is subjected to bladder pressure detection after drinking water, and the pressure detection is completed after the target user finishes urinating. The period from the start of drinking water to the end of urination constitutes a pressure cycle, and the historical pressure information may include multiple pressure cycles. When obtaining the historical drinking information and historical urination information, it is necessary to obtain all the historical information according to the number of cycles included in the historical pressure information. The historical drinking information includes the drinking amount and drinking time of each drinking, and the historical urination information includes the urination start time and urination end time and urination amount, etc. After obtaining the historical drinking information, the target user is subjected to bladder pressure detection. The historical water consumption information and historical urination information are collected and marked in the historical pressure information according to the corresponding time, so as to determine the peak and valley values ​​of the bladder pressure. The historical water consumption information, historical urination information, historical pressure information and pressure peak and valley information are arranged and marked to determine that the pressure change report records the changing trend of the bladder pressure since drinking water, and the rate of change from the peak value to the valley value after reaching the peak value, etc., so that the pressure change pattern of the bladder of the target user under different water drinking amounts and different drinking time conditions can be determined according to the pressure change report, and the pressure change pattern can be used as the standard bladder data to facilitate the subsequent comparison and verification of the bladder pressure data collected by the pressure sensor according to the standard bladder data.

[0037] Step S103 : determining whether the bladder pressure data contains normal data based on the standard bladder data.

[0038] For step S103, the pressure peak and pressure valley values ​​are determined based on the bladder pressure data; the current change data of the target user is determined based on the pressure collection information, the pressure peak and pressure valley values; the pressure difference is determined based on the current change data and the pressure change law; the difference judgment rule is obtained; and whether the bladder pressure data contains normal data is determined based on the pressure difference and the difference judgment rule.

[0039] In this embodiment, after obtaining bladder pressure data, the peak and valley pressure values ​​of the bladder pressure values ​​corresponding to each pressure sensor in the bladder pressure data are determined. The bladder pressure values ​​corresponding to each pressure sensor are then determined to be normal data using the same method. If the bladder pressure value corresponding to one of the pressure sensors is normal data, the bladder pressure data is determined to contain normal data; otherwise, the bladder pressure data is determined to contain no normal data. Before determining normal data according to the difference determination rule, the target user's current change data is determined based on the pressure acquisition information, the peak and valley pressure values. The current change data is the pressure change trend between the two valley pressure values, as well as the rate of change from the peak value to the valley value after reaching the peak value. The pressure difference is then determined based on the obtained pressure change pattern. The difference determination rule sets a difference threshold. When the pressure difference is greater than or equal to the difference threshold, it is determined to be abnormal data; when the pressure difference is less than the difference threshold, it is determined to be normal data.

[0040] Furthermore, determining the pressure difference based on the current change data and the pressure change law includes: obtaining current drinking water information; determining drinking water difference data based on the current drinking water information and historical drinking water information; determining a comparison time point based on the current change data, the current drinking water information and the pressure acquisition information; selecting data from the pressure change law based on the comparison time point and the current drinking water information to obtain comparison data to be used; determining the pressure difference based on the drinking water difference data, the current change data and the comparison data to be used.

[0041] The current drinking information is the amount and time of the first drink in the bladder's idle state after the target user finishes urinating and inserts the capsule detector. The amount of water consumed is marked as the current amount of water consumed, and the time of water consumed is marked as the current time of water consumed. The historical drinking information is searched for a consistent historical drinking amount. If a consistent amount exists, the drinking difference data is marked as empty and the corresponding data is extracted from the pressure variation pattern to obtain the standby pattern data. If a consistent amount does not exist, the difference between the historical and current drinking amounts is calculated. The drinking difference with the smallest difference is used as the drinking difference data. The data corresponding to the smallest difference is extracted from the pressure variation pattern to obtain the standby pattern data. Based on the current variation data, a time point is selected from the current drinking information and the pressure collection information. The selected time point is used as the comparison time point. The selected comparison time point must include the current drinking time, the time of the pressure peak, and the time of the pressure valley, and must also include the time between the current drinking time and the pressure peak. Data is selected from the regular data to be used according to the comparison time point, that is, the pressure value corresponding to the same time point in the regular data to be used is selected and used as the comparison data to be used. After obtaining the comparison data to be used, the pressure difference is determined using the drinking water difference data, the current change data and the comparison data to be used. Specifically, when the drinking water difference data is empty, the data difference between the current change data and the comparison data to be used is directly calculated and used as the pressure difference. When the drinking water difference data is not empty, the comparison data to be used is adjusted and calculated based on the calculated drinking water difference and the preset ratio to obtain the adjusted data to be used. The data difference between the current change data and the adjusted data to be used is calculated and used as the pressure difference. The preset ratio is a difference adjustment ratio set according to the actual bladder pressure change caused by the actual drinking water difference. The specific preset ratio needs to be set according to the actual difference change situation, and is not specifically limited here.

[0042] Step S104: If the bladder pressure data includes normal data, the normal data is used as the pressure data to be used.

[0043] In this embodiment, if the bladder pressure data includes normal data, the bladder pressure value corresponding to the normal data is extracted, and the corresponding sensor number is determined, so as to use it as the pressure data to be used. In addition, the bladder pressure value in the pressure data to be used is not unique, that is, multiple bladder pressure values ​​collected by multiple sensors are allowed to exist.

[0044] Step S105: Generate a pressure detection report based on the pressure data to be used and the pressure collection information.

[0045] In this embodiment, after the pressure data to be used is determined, the corresponding pressure collection information to be used is extracted from the pressure collection information according to the sensor label corresponding to the pressure data to be used, the pressure collection time point in the pressure collection information to be used is matched with each bladder pressure value in the pressure data to be used, and the corresponding discount graph and pressure value annotation are generated to obtain a pressure detection report.

[0046] Step S106 : If the bladder pressure data does not include normal data, the bladder pressure data is corrected based on the normal data to generate corrected pressure data.

[0047] For step S106, the pressure type period is divided based on the pressure change pattern and normal data; the abnormal threshold of the pressure type period is obtained; the abnormal data point in the bladder pressure data is determined based on the abnormal threshold; it is determined whether the number of abnormal points of the abnormal data point is not less than the preset number threshold; if the number of abnormal points of the abnormal data point is less than the preset number threshold, the adjacent normal data of the abnormal data point is obtained; the abnormal data point is corrected based on the adjacent normal data to generate corrected pressure data; if the number of abnormal points of the abnormal data point is not less than the preset number threshold, it is determined that the abnormal data point cannot be corrected and data unavailable information is generated.

[0048] In this embodiment, when correcting pressure data, it is first necessary to determine whether the pressure data can be corrected. If so, the abnormal data is corrected. If not, all data detected by the corresponding pressure sensor is directly treated as unavailable data, extracted, and marked to generate unavailable information. Before making this determination, the pressure is divided into different periods based on the pressure variation pattern and normal data, resulting in pressure type periods. Pressure type periods include emptying, filling, and stable periods, and different abnormal thresholds are corresponding to different periods. The bladder pressure data is compared with the abnormal threshold to obtain abnormal data points. The number of abnormal data points is then counted to obtain the number of abnormal points. When the number of abnormal points is greater than or equal to a preset number threshold, correction is determined to be unavailable. When the number of abnormal points is less than the preset number threshold, correction is determined to be possible. The abnormal data points are then corrected based on their adjacent normal data.

[0049] Furthermore, the abnormal data point is corrected based on the adjacent normal data to generate the corrected pressure data, including: obtaining the abnormal timestamp of the abnormal data point and the normal timestamp of the adjacent normal data; calculating the correction value based on the abnormal timestamp, the normal timestamp, the preset calculation formula, the abnormal data point and the adjacent normal data; and using the correction value as the corrected pressure data.

[0050] When making corrections, a linear difference formula is used for correction. That is, the preset formula is a linear difference formula. After obtaining the abnormal timestamp of the abnormal data point and the normal timestamp of the adjacent normal data, the abnormal timestamp, normal timestamp, abnormal data point and adjacent normal data are brought into the preset calculation formula to calculate the correction value. The preset formula is ; Among them, Pcorrected is the correction value, Pbefore is the previous normal data, Pafter is the next normal data, t is the abnormal timestamp, tbefore is the previous normal timestamp, and tafter is the next normal timestamp.

[0051] Step S107: Generate a pressure detection report based on the corrected pressure data and the pressure acquisition information.

[0052] In this embodiment, the pressure detection report is generated in the same manner as the pressure data to be used, that is, after the revised pressure data is obtained, the corresponding pressure collection information to be used is extracted from the pressure collection information according to the sensor label corresponding to the revised pressure data, the pressure collection time point in the pressure collection information to be used is matched with each bladder pressure value in the revised pressure data, and the corresponding discount diagram and pressure value annotation are generated to obtain the pressure detection report.
