Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and particularly to an intelligent postoperative drainage device based on drainage induction monitoring, an application control method thereof, and an electronic device. Background Art

[0002] A drainage ball is a postoperative drainage device in surgery. It is generally made of medical-grade materials such as polyurethane or silica gel, and is connected to a drainage catheter inserted into the body, acting as a negative pressure conduction medium and guiding and collecting the drained fluid. It is mainly used in clinical surgeries to suck pus, exudate, effusion, or tissue out of the body through negative pressure, so as to reduce tissue damage, prevent bacterial infection, and improve the wound healing efficiency.

[0003] The disposable negative pressure drainage ball commonly used clinically, as shown in Figure 1 has the characteristics of small size, convenient to carry, and powerful negative pressure drainage function. It is made of transparent material, which is convenient for medical staff to observe the drainage situation (there is a drainage scale on the appearance); at the same time, it has good sealing performance and can effectively prevent the spread of infection.

[0004] However, with clinical applications, it is found that the use of the drainage ball is relatively inconvenient, and there are the following clinical application defects:

[0005] For traditional drainage balls, nurses need to clinically monitor and check the drainage volume of patients to give drainage warnings and replace the drainage balls, so it consumes a lot of time and energy of nurses and wastes nursing resources;

[0006] It is impossible to achieve intelligent online drainage supervision, and it is impossible to directly monitor the working status of the drainage balls of each patient in the nurse station background, with low intelligence;

[0007] It is impossible to enable medical staff or family members to achieve online follow-up observation at any time through the way of background online supervision, and it is not convenient to record drainage data in real time online. Summary of the Invention

[0008] To solve the above problems, the present application proposes an intelligent postoperative drainage device based on drainage induction monitoring, an application control method thereof, and an electronic device.

[0009] On the one hand, the present application proposes an intelligent postoperative drainage device based on drainage induction monitoring, including a drainage ball 1, and a smart induction module 3 is configured on the drainage ball 1 for sensing and monitoring the drainage volume of the drained fluid in the drainage ball 1 and the recognition result of the liquid color;

[0010] The intelligent induction module 3 is communicatively connected to the nurse station background 5 through the in-hospital gateway 4, and reports the current patient's drainage volume and the liquid color recognition result to the nurse station background 5 in real time.

[0025] After activating the intelligent sensing module 3, the intelligent sensing module 3 reports a work instruction to notify the nurse station background 5;

[0026] The nurse station background 5 issues configuration information to the intelligent sensing module 3, and the configuration information includes the alarm threshold for the drainage volume / liquid color recognition result;

[0027] The MCU of the intelligent sensing module 3 makes a warning judgment on the drainage volume / liquid color recognition result monitored by the sensor:

[0029] If not, continue to monitor.

[0030] Preferably, the alarm threshold for the drainage volume is: the maximum drainage volume per hour. If the drainage volume monitored by the sensor per hour exceeds the maximum drainage volume per hour, trigger an alarm, including:

[0060] In addition, for a better description of the present disclosure, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present disclosure can also be implemented without some specific details. In some instances, means, elements and circuits well - known to those skilled in the art are not described in detail so as to highlight the gist of the present disclosure.

[0061] Embodiment 1

[0062] As Figure 2 shown, on one hand, the present application proposes an intelligent postoperative drainage device based on drainage induction monitoring, including a drainage ball 1, and a smart induction module 3 is configured on the drainage ball 1 for sensing and monitoring the drainage volume of the drainage fluid in the drainage ball 1 and the recognition result of the liquid color;

[0063] The smart induction module 3 is communicatively connected to the nurse station background 5 through the hospital gateway 4, and reports the current patient's drainage volume and the recognition result of the liquid color to the nurse station background 5 in real time, and the nurse station background 5 records and stores the current patient's drainage volume and the recognition result of the liquid color.

[0064] In the present invention, an intelligent sensing device (a wireless module with a display, sensors, a controller, etc., a small screen, which can display the real-time drainage volume and color monitoring of the drainage fluid through built-in sensors such as gravity, and report to the background) is configured on the drainage ball. The drainage volume can not only be directly displayed on the drainage ball, but also be connected to a mobile phone mini-program to record the color and volume of the patient's drainage fluid in real time and perform background statistical analysis. The maximum drainage volume can be set, and if the maximum drainage volume per hour is exceeded, the app will give an alarm prompt. This APP can not only meet the needs of patients to observe the drainage volume in the hospital and at home, but also allow medical staff and patients to log in simultaneously, facilitating doctors' follow-up observations.

[0065] The hardware design of the intelligent sensing device is designed and applied according to the module composition of the present invention. Its external structure and dimensions are not limited, and the hardware designs of existing Internet of Things modules or smart wristbands, bracelets, etc. can be referred to.

[0066] The intelligent sensing module 3 can be pasted or fixed at the bottom of the drainage ball through hot melt adhesive, etc.

[0067] As Figure 3 shown, preferably, the intelligent sensing module 3 includes:

[0068] MCU;

[0069] A pressure sensing film 2 (i.e., a film type pressure sensor), which is arranged at the bottom of the drainage ball 1 and is used to sense the pressure signal of the drainage fluid in the drainage ball 1;

[0070] A signal processor, which is used to perform digital-to-analog processing on the pressure signal to obtain the corresponding pressure value. After being converted and calculated by the MCU according to the preset pressure-weight conversion rule, the drainage volume of the drainage fluid is obtained;

[0071] A display, which is used to display the drainage volume;

[0072] An infrared module, which is used to emit an infrared signal into the drainage ball 1 and send the feedback infrared feedback signal to the MCU. After the MCU analyzes and calculates the intensity and wavelength of the infrared feedback signal, the liquid color recognition result of the drainage fluid in the drainage ball 1 is obtained;

[0073] A wireless communication module, which is used to report the drainage volume and the liquid color recognition result of the drainage fluid in the drainage ball 1 to the in-hospital gateway 4, and then the in-hospital gateway 4 reports it to the nurse station background 5. The nurse station background 5 records and saves the drainage volume and the liquid color recognition result of the current patient;

[0074] A power supply, which is used for power supply;

[0075] The pressure sensing film 2, the signal processor display, the infrared module, the wireless communication module, and the power supply are respectively electrically connected to the MCU.

[0076] This solution can monitor the volume of the drainage fluid and the color of the fluid in the monitor.

[0077] Through the thin-film pressure sensor set at the bottom inside the drainage ball, the pressure signal of the internal drainage fluid is monitored, and after signal processing and conversion calculation, the weight of the drainage fluid is obtained.

[0078] Through the infrared module set on the outer wall of the drainage ball, infrared rays are excited and the reflected infrared light is received. Through the changes in light intensity and wavelength, the color difference is judged to identify the recognition result brought by the color of the drainage fluid (the ability of different colors to wash infrared light is different).

[0079] The intelligent induction module 3 can communicate with the background through the Internet of Things. The background records its device number and binds it to the current patient's visit ID.

[0080] System architecture

[0081] 1. Pressure sensing film: Used to sense the pressure signal of the drainage fluid,

[0082] 2. Signal processor: Perform digital-to-analog processing on the pressure signal and convert it into the drainage volume.

[0083] 3. Infrared module: Used to identify the color of the drainage fluid.

[0084] 4. Wireless communication module: Report the drainage volume and the recognition result of the liquid color to the nurse station background.

[0086] 5. Nurse station background: Record and save the data and provide a visualization interface.

[0087] Specific implementation:

[0088] 1. Pressure sensing film

[0089] Location: Set at the bottom of the drainage ball.

[0090] Function: Sense the pressure signal of the drainage fluid.

[0091] Output: Analog pressure signal P(t).

[0092] 2. Signal processor

[0093] Function: Perform digital-to-analog conversion on the pressure signal P(t) to obtain the digital pressure value Pa(t). Generally, digital-to-analog signal processing is performed by a DSP digital-to-analog converter, etc., or processed by an A / D conversion circuit, and it can be implemented in combination with the existing A / D conversion circuit.

[0094] According to the preset pressure-weight conversion rule, calculate the drainage volume Q(t):

[0095] Q(t) = k·Pa(t) + b,

[0096] k: Conversion coefficient (calibrated by experiment),

[0097] b: Bias (calibrated by experiment, can be determined according to patient attributes, such as attributes of men, women, the elderly, and children),

[0098] Q(t): Drainage volume (unit: mL).

[0099] By experimentally measuring the drainage volume of patients under several different pressures, k and b are determined by fitting. Based on the conversion relationship between weight and pressure, corresponding conversion rules can be set.

[0100] 3. Display

[0101] Function: Real-time display of the drainage volume Q(t). Display content: Current drainage volume, historical drainage volume curve (the relationship curve between time and drainage volume (which can also be the recognition value of color) determined according to the drainage volume collected at each time point).

[0102] 4. Infrared module (infrared transceiver)

[0103] Function:

[0104] 1). Send an infrared signal into the drainage ball.

[0105] 2). Receive the infrared feedback signal and analyze its intensity and wavelength.

[0106] 3). Identify the liquid color of the drainage fluid according to the infrared feedback signal.

[0107] Color = IR_Classifier(I(λ), λ),

[0108] I(λ) is the intensity of the infrared feedback signal, λ is the wavelength of the infrared feedback signal, and IR_Classifier is an infrared signal classifier (such as a support vector machine or a neural network, which can be classified through a program block embedded in the MCU, such as a pre-trained CNN color recognition model, so as to realize intelligent color recognition and classification. Specifically, it can combine the big data composed of corresponding infrared feedback signals of different colors and recognition results to train the CNN model, so as to obtain the CNN color recognition model and load it in the background or the MCU built-in program).

[0109] The technical principle of identifying the color of the drainage fluid by exciting infrared light with an infrared transceiver and receiving the infrared feedback signal is mainly based on the absorption and reflection characteristics of infrared light and spectral analysis technology:

[0110] First, the transmitting part in the infrared transceiver emits infrared light towards the drainage ball. As an electromagnetic wave, infrared light has the characteristics of low energy, short wavelength, and strong penetration. When the infrared light irradiates the drainage fluid in the drainage ball, the drainage fluid will absorb part of the infrared light and also reflect part of the infrared light. The color and composition of the drainage fluid will affect its absorption and reflection characteristics of infrared light.

[0111] Next, the receiving part of the infrared transceiver receives the reflected infrared feedback signal. This signal contains the absorption and reflection information of the drainage fluid to infrared light. Through precise optoelectronic conversion devices, such as photodiodes, the received infrared light signal is converted into an electrical signal for subsequent analysis and processing.

[0112] Then, the received infrared feedback signal is analyzed and calculated. This includes measuring the wavelength and intensity changes of the feedback signal. Since the absorption and reflection characteristics of infrared light by drainage fluids of different colors and compositions are different, the wavelength and intensity of the reflected infrared light will also be different. By comparing and analyzing these differences, the color and possible composition of the drainage fluid can be inferred.

[0113] Finally, spectral analysis technology is used to further confirm the color of the drainage fluid. Spectral analysis technology is a method of inferring the composition of a substance by measuring the absorption or reflection intensity of the substance to light of different wavelengths. In this technology, a known infrared spectrum database or a special infrared spectrum model can be used to compare the received infrared feedback signal with the spectral data in the database, so as to more accurately identify the color of the drainage fluid.

[0114] In summary, the technical principle identifies the color of the drainage fluid by exciting infrared light and receiving the reflected infrared feedback signal, and using spectral analysis technology. This method has the advantages of non-contact detection, simple operation, accurate measurement, etc., and has broad application prospects in the fields of medical treatment, chemical industry, etc.

[0115] 5. Wireless communication module (Bluetooth module can be used to communicate with the background through the in-hospital gateway)

[0116] Function:

[0117] 1). Package the drainage volume Q(t) and the liquid color recognition result Color into a data packet.

[0118] 2). Report to the nurse station background through the in-hospital gateway. Communication protocol: Support Wi-Fi, Bluetooth or LoRa.

[0119] 6. Nurse station background

[0120] Function:

[0121] 1). Receive and store the drainage volume and the liquid color recognition result.

[0122] 2). Provide a visual interface to display data in real time.

[0123] 3). Trigger an alarm according to preset rules (such as abnormal drainage volume or abnormal liquid color). For specific understanding, please refer to the following description.

[0124] Preferably, the wireless communication module adopts the following wireless communication modes:

[0125] 4 / 5G, Bluetooth, WIFI ZigBee, NFC, GSM / CDMA, WiMAX, satellite communication or microwave communication.

[0126] Preferably, the MCU adopts an ESP series of microcontroller chips.

[0129] Embodiment 2

[0130] Based on the implementation principle of Embodiment 1, on the other hand, the present application proposes an application control method for an intelligent postoperative drainage device based on drainage induction monitoring, including the following steps:

[0131] On the nurse station background 5, bind the current patient's visit ID with the device number of the intelligent induction module 3 on the drainage ball 1 assigned to him;

[0132] After activating the intelligent induction module 3, the intelligent induction module 3 reports a work instruction to notify the nurse station background 5;

[0133] The nurse station background 5 issues configuration information to the intelligent sensing module 3, and the configuration information includes alarm thresholds for the drainage volume / liquid color recognition results (the alarm threshold for the drainage volume is the maximum drainage volume per hour; the alarm threshold for the liquid color recognition result is the chromaticity value of the drainage liquid color after a certain duration);

[0134] The MCU of the intelligent sensing module 3 makes early warning judgments on the sensed and monitored drainage volume / liquid color recognition results:

[0135] If the drainage volume / liquid color recognition result meets the alarm threshold, a corresponding early warning signal is generated and displayed on the display, and at the same time, the early warning signal of the drainage volume / liquid color recognition result is reported;

[0136] If not, continue to monitor.

[0137] When the patient is undergoing drainage, a drainage device is worn for the patient. Nurses or family members can log in to the background through the APP terminal, report the information of the drainage patient and the device number, and bind the patient's medical treatment ID (or identity ID) and the device module number on the background to facilitate subsequent recording and binding of the patient's drainage monitoring data.

[0138] For inpatients, nurses can also input and bind the above information on the nurse station background server.

[0139] Technical implementation steps:

[0140] Binding of the patient's medical treatment ID and the device number:

[0141] When the patient arrives at the nurse station and needs to use a drainage ball, the nurse inputs the patient's medical treatment ID through the nurse station background system.

[0142] The system automatically selects the corresponding drainage ball device and binds its device number to the patient's medical treatment ID.

[0143] The bound information is stored in the database of the nurse station background for subsequent use.

[0144] Activating the intelligent sensing module:

[0145] The nurse hands the drainage ball to the patient and activates the intelligent sensing module (possibly by pressing a button, scanning a QR code, etc.).

[0146] After the intelligent sensing module is activated, it immediately reports a work instruction to the nurse station background, indicating that it has started working.

[0147] Issuing configuration information:

[0148] After receiving the work instructions, the nurse station backend sends the configuration information to the intelligent sensing module according to the preset rules or the patient's specific situation.

[0149] The configuration information includes alarm thresholds for drainage volume and liquid color recognition results. For example, when the maximum drainage volume per hour is 200 ml and the color value of the drainage fluid reaches a certain threshold, an alarm is triggered.

[0150] Real-time monitoring and early warning judgment:

[0151] The sensors built into the intelligent sensing module begin to monitor the drainage volume and liquid color in real time.

[0152] The MCU processes the sensor monitoring data and compares it with the issued alarm threshold.

[0153] If the drainage volume or liquid color recognition result meets the alarm threshold (for example, the drainage volume exceeds 200 ml / h, or the drainage fluid color reaches a preset chromaticity value), the MCU generates a corresponding early warning signal.

[0154] Display and report warning information:

[0155] The early warning signal is sent to the back-end of the nurse station and displayed on the monitor in real time to alert the nurse.

[0156] At the same time, early warning signals can also be recorded in the system for subsequent analysis and processing.

[0157] Nurses take appropriate measures based on the early warning information, such as timely checking the patient's condition and adjusting the treatment plan.

[0158] Continue to monitor:

[0159] If the drainage volume or liquid color recognition results do not meet the alarm threshold, the MCU will continue to monitor and wait for the next data update.

[0160] This process will continue until the patient no longer needs to use the drainage bulb or the nurse releases the binding.

[0161] Advantages of technical solutions

[0162] Real-time monitoring: Through the integration of the intelligent sensing module and the nurse station background, real-time monitoring of patient drainage conditions is achieved.

[0163] Early warning function: When the drainage volume or liquid color reaches the preset alarm threshold, the system can automatically trigger an early warning signal to remind the nurse to take timely measures.

[0164] Data recording and analysis: All monitoring data and warning information can be recorded in the system to facilitate subsequent data analysis and processing.

[0165] Improve nursing efficiency: Through the automated monitoring and warning functions, the workload of nurses is reduced, and the nursing efficiency and quality are improved.

[0166] Therefore, the present invention can achieve the intelligent management of the drainage ball device and the effective monitoring of patients.

[0167] Preferably, the alarm threshold of the drainage volume is: the maximum drainage volume per hour. If the drainage volume sensed and monitored per hour exceeds the maximum drainage volume per hour, an alarm is triggered, including:

[0168] Use the discretization formula to calculate the total drainage volume S(t):

[0169]

[0170] Q(t i ) is the drainage volume at the i-th hour,

[0171] Δt is the time interval,

[0172] n is the number of hours between the current time t and the starting time t0;

[0173] According to the total drainage volume S(t) and the preset threshold T, determine whether it is necessary to trigger the drainage warning:

[0174]

[0175] Warning(t) is the warning signal, 1 indicates that the warning is triggered, and 0 indicates that no warning is triggered in other situations.

[0176] Through the above algorithm calculation and judgment, it is possible to judge the drainage warning based on the maximum drainage volume per hour.

[0177] For the chromaticity value reflected by the color of the drainage fluid after one hour, it is the same as shown above (the threshold is the chromaticity value range after one hour).

[0178] Preferably, it further includes:

[0179] The intelligent sensing module 3 reports the current patient's drainage volume and the liquid color recognition result to the nurse station background 5 at a preset frequency;

[0180] The nurse station background 5 receives and saves the drainage volume and the liquid color recognition result at each time point, and writes them into the current patient's medical record;

[0181] Read the drainage data in the medical record and generate an analysis curve between the corresponding time and the drainage volume and the liquid color recognition result.

[0182] Preferably, it further includes:

[0183] According to the preset message queue mechanism, the nurse station background 5 issues the current patient's medical record and the data analysis curve to the APP terminals of the corresponding personnel.

[0184] Example description

[0185] Drainage device: Built-in intelligent sensing module, which can automatically measure and record the patient's drainage volume and the recognition result of the liquid color according to a preset frequency (such as once per hour).

[0186] Nurse station background: A central management system responsible for receiving, storing, processing, and analyzing data from the drainage device, and generating the patient's medical record and data analysis curve.

[0187] APP terminal: A mobile device application used by medical staff or family members to receive the patient's medical record and data analysis curve issued by the nurse station background. Preferably, the PDA terminal adopted by nurses can interact with the background through the APP for drainage management.

[0188] Technical implementation steps:

[0189] Intelligent sensing module reports data:

[0190] The intelligent sensing module in the drainage device automatically measures the patient's drainage volume and the liquid color according to a preset frequency (such as once per minute), and packs these data into a data packet.

[0191] The intelligent sensing module uploads the data packet to the nurse station background through a wireless network (such as Wi-Fi, Bluetooth, etc.).

[0192] Nurse station background receives and saves data:

[0193] After receiving the data packet from the intelligent sensing module, the nurse station background first parses it to extract the drainage volume and the recognition result of the liquid color.

[0194] The system saves these data to the database according to the time point and generates or updates the medical record for the current patient. The medical record contains the patient's basic information and the drainage volume and the recognition result of the liquid color at all time points.

[0195] Generate data analysis curve:

[0196] The nurse station background regularly (such as once per hour) reads the drainage data in the medical record.

[0197] The system uses data analysis algorithms to generate data analysis curves based on the time point and the corresponding drainage volume and the recognition result of the liquid color. These curves can intuitively display the changing trend of the patient's drainage situation over time.

[0198] Issuing the medical record and data analysis curve:

[0199] Based on the preset message queue mechanism, the back-end of the nurse station packages the medical record and data analysis curve of the current patient into a message.

[0200] The system sends the message to the APP terminals of the corresponding medical staff through a push service (such as APNs, Firebase Cloud Messaging, etc.).
