Description

Technical Field

[0001] This invention relates to the field of drainage tube monitoring technology, and in particular to a high-precision drainage tube monitoring system. Background Technology

[0002] In many surgical procedures, including biliary tract surgeries, thoracoscopic surgeries, gastrointestinal surgeries, and pancreatic surgeries, drainage tubes are required postoperatively. These tubes drain blood and fluid from the abdominal and pleural cavities, allowing for observation of the drainage fluid to assess for conditions such as abdominal hemorrhage, ascites, infection, or anastomotic leakage. However, while drainage tubes serve their positive function, they also increase the probability of complications, including postoperative infection, tube obstruction, and tube dislodgement, affecting postoperative recovery. Therefore, postoperative monitoring and protection of drainage tubes are crucial. Currently, the following methods are primarily used for fixation, labeling, and observation after surgery.

[0003] Fixation and Labeling: After changing the dressing, surgical drainage tubes are typically marked with a marker or tape around the tube to record the distance it has been pulled out. Medical tape or 3M tape is then used to secure it, preventing dislodgement and recording the drainage distance. A paper label is also used to name the drainage tube, such as "pancreatic anastomosis drainage tube" or "pelvic drainage tube," facilitating later observation and recording of drainage volume. However, this fixation and labeling method has the following problems: When patients have ascites or infection with bleeding, excessive drainage fluid can increase the fluid on the surface of the drainage tube, causing the tape and paper label to seep through, easily leading to the tape and label falling off. This makes it impossible to distinguish the type of drainage tube, resulting in poor fixation.

[0004] Observation: Observation of patients with drainage tubes generally includes observation of the wound and the drainage tube itself. Patient observation primarily involves observing the appearance of the wound dressing and checking for bleeding or exudation. This is usually done during nurses' shift handover or doctors' rounds, with appropriate dressing changes and care provided based on the patient's condition. Additionally, observation of drainage fluid is typically done during rounds or when caring for the drainage tube, noting the nature and amount of the fluid. The main problems with these observation methods are: postoperative patients often experience significant exudation, and abdominal binders are frequently used for abdominal protection. However, this can obscure the wound and part of the drainage tube, making it difficult for medical staff to immediately assess and address any issues that may arise at the insertion site. Furthermore, literature research indicates that most cases of tube dislodgement and bleeding occur during night shifts, where staff shortages and poor lighting further hinder timely assessment of the wound and drainage fluid, impacting the timeliness of any abnormalities.

[0005] Therefore, there is an urgent need to provide a high-precision drainage tube monitoring system that can promptly detect abnormalities in the patient's wound and drainage tube, thereby alerting medical staff to take timely action. Summary of the Invention

[0006] This invention provides a high-precision drainage tube monitoring system that can promptly alert when liquid seeps out of the drainage tube, enabling real-time monitoring of abnormal drainage conditions.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A high-precision drainage tube monitoring system includes an adjustable fixing strap and a drainage tube monitoring terminal;

[0009] The adjustable fixing strap is used to connect to the drainage tube; the adjustable fixing strap is equipped with a humidity sensor and a controller;

[0010] Both the humidity sensor and the drainage tube monitoring terminal are electrically connected to the controller.

[0011] The humidity sensor is used to detect the humidity on the outer wall of the drainage tube and to feed back the humidity monitoring results to the controller.

[0012] The controller is used to transmit humidity monitoring results to the drainage tube monitoring terminal;

[0013] The drainage tube monitoring terminal includes a humidity analysis module, a liquid source analysis module, and an anomaly alert module;

[0014] The humidity analysis module is used to acquire humidity monitoring results, analyze whether the humidity on the outer wall of the drainage tube is greater than the preset humidity, and generate humidity analysis results.

[0015] The liquid source analysis module is used to acquire an image of the drainage tube area and analyze the liquid flow direction to generate a liquid source analysis result if the humidity analysis result shows that the humidity of the outer wall of the drainage tube is greater than the preset humidity.

[0016] The anomaly alert module is used to generate a leakage anomaly alert based on the liquid source analysis results.

[0017] The principle and advantages of this invention are as follows: An adjustable fixing band is used to wrap around the drainage tube. Compared to using paper tape and markers, this prevents the band from falling off due to fluid seepage from the drainage tube. Furthermore, the adjustable fixing band can be reused, saving medical costs. A humidity sensor is installed inside the adjustable fixing band. When fluid seepage occurs in the drainage tube, it can be detected promptly. The fluid source analysis module acquires an image of the drainage tube area, analyzes the fluid flow direction, and confirms whether the fluid on the drainage tube is wound exudate, improving the reliability of drainage tube exudate assessment. Simultaneously, the image of the drainage tube area is acquired only when the humidity analysis result shows that the humidity of the outer wall of the drainage tube is greater than a preset humidity, ensuring timely exudate analysis while reducing system power consumption. In summary, this solution can promptly alert when fluid seeps from the drainage tube, enabling real-time monitoring of abnormal drainage conditions, facilitating timely dressing changes by medical staff, and preventing infection.

[0018] Furthermore, one end of the adjustable fixing strap is provided with several through holes, and the other end is provided with a protrusion. The adjustable fixing strap is detachably connected to the drainage tube by fastening the protrusion into the through holes.

[0019] Beneficial effects: The adjustable fixing strap can be fixed and its size can be adjusted by inserting the protrusion into the through hole, making it suitable for drainage tubes of various diameters.

[0020] Furthermore, the adjustable fixing strap is provided with a groove, and the humidity sensor and controller are both disposed in the groove.

[0021] Beneficial effect: The humidity sensor and controller are placed in the groove, which helps to fix the components.

[0022] Furthermore, adhesive strips are provided on both sides of the groove.

[0023] Beneficial effects: The adjustable fixing strap with adhesive strip can achieve more stable fixation and prevent the drainage tube from falling off.

[0024] Furthermore, the adjustable fixing strap is equipped with an NFC tag for marking the name of the drainage tube.

[0025] Beneficial effects: Using NFC tags to record the name of the drainage tube allows the data (drainage tube name) in the NFC tag to be read by a corresponding NFC device. Compared with existing paper tags, it will not be contaminated by leakage. Even if the drainage tube leaks, the information of the corresponding drainage tube can be quickly obtained. Moreover, compared with paper tags, the content stored in the NFC tag can be modified, which is conducive to the overall reuse of the adjustable fixing band.

[0026] Furthermore, a color sensor is also provided in the groove, and the color sensor is electrically connected to the controller;

[0027] The color sensor is used to monitor the color of the drainage fluid in the drainage tube and to send the color monitoring results back to the controller.

[0028] The controller is used to transmit the color monitoring results to the drainage tube monitoring terminal;

[0029] The drainage tube monitoring terminal also includes a drainage fluid anomaly analysis module, which is used to analyze the color anomaly of the drainage fluid based on the color monitoring results and generate drainage fluid anomaly analysis results;

[0030] The abnormality alert module is also used to generate an abnormality alert for the drainage fluid based on the abnormality analysis results.

[0031] Beneficial effects: It monitors the color of the drainage fluid in the drainage tube, analyzes whether there are any abnormalities in the color of the fluid in the drainage tube, and thus issues timely alerts for abnormal drainage fluid.

[0032] Furthermore, the drainage tube monitoring terminal also includes a body temperature detection module;

[0033] The body temperature detection module is used to acquire the user's body temperature data based on the humidity analysis results, analyze whether the user's body temperature is abnormal, and generate body temperature analysis results.

[0034] The abnormality alert module is also used to generate an abnormal body temperature alert based on the body temperature analysis results.

[0035] Beneficial effects: Based on the humidity analysis results, the user's body temperature data can be obtained, so that when abnormalities such as leakage occur in the drainage tube, the patient's body data can be collected in a timely manner, so as to prompt medical staff who go to treat the patient's wound to understand the patient's condition in advance and take appropriate measures.

[0036] Furthermore, the adjustable fixing strap is made of fluorescent material.

[0037] Beneficial effects: The adjustable fixation strap using fluorescent material allows for nighttime rounds without repeatedly turning on the lights to check the patient's wound and drainage tubes, thus reducing the impact of observing drainage tubes on the patient's sleep. At the same time, the fluorescent material helps medical staff locate the drainage tubes more quickly, improving the efficiency of rounds. Attached Figure Description

[0038] Figure 1 This is a schematic diagram of the adjustable fixing belt in an embodiment of a high-precision drainage tube monitoring system of the present invention.

[0039] Figure 2 This is a logic block diagram of an embodiment of a high-precision drainage tube monitoring system of the present invention. Detailed Implementation

[0040] The following detailed description illustrates the specific implementation method:

[0041] The markings in the accompanying drawings include: 1. Adjustable fixing strap; 2. Humidity sensor; 3. Color sensor; 4. Controller; 5. Groove; 6. Through hole; 7. Protrusion; 8. Adhesive strip.

[0042] Example 1:

[0043] A high-precision drainage tube monitoring system includes an adjustable fixing band 1 and a drainage tube monitoring terminal. In this embodiment, the adjustable fixing band 1 is made of fluorescent material. In other embodiments of this application, an adhesive adjustable fixing band 1 can also be used, and then fluorescent dye is sprayed onto the surface of the adhesive adjustable fixing band 1.

[0044] The adjustable fixing strap 1 is used to connect to the drainage tube. It not only facilitates subsequent observation of whether the drainage tube has shifted by uniformly setting its initial position on the drainage tube, but also serves to fix the components on the drainage tube. In this embodiment, one end of the adjustable fixing strap 1 has several arrayed through holes 6, and the other end has protrusions 7. The adjustable fixing strap 1 is detachably connected to the drainage tube by fastening the protrusions 7 into the through holes 6, and can be adapted to drainage tubes of different diameters by adjusting the specific through holes 6 into which it is fastened.

[0045] like Figure 2 As shown, the adjustable fixing band 1 is equipped with a humidity sensor 2, a color sensor 3, and a controller 4; the adjustable fixing band 1 has a groove 5, and the humidity sensor 2, color sensor 3, and controller 4 are all located in the groove 5; adhesive strips 8 are provided on both sides of the groove 5, so that after the adjustable fixing band 1 is fixed to the drainage tube, it can be fixed again by the adhesive strips 8; the adhesive strips 8 are provided with double-sided release paper, which can be washed and dried after use, and then used to isolate dust, realizing reuse. In actual use, only the double-sided release paper on the adhesive strip 8 away from the patient's wound needs to be removed, so that the exudate can flow to the location of the sensor while achieving the fit between the adjustable fixing band 1 and the drainage tube; and in this solution, adhesive strips 8 are provided on both sides, so medical staff do not need to distinguish the front and back when fixing the adjustable fixing band 1 to the drainage tube, which improves the convenience of use. The adjustable fixing band 1 is equipped with an NFC tag for marking the name of the drainage tube. Medical staff can bring the NFC tag close to the corresponding NFC terminal to display the data stored in the NFC tag on the terminal. In this embodiment, the NFC tag is embedded in the adjustable fixing band 1.

[0046] The humidity sensor 2, color sensor 3, and drainage tube monitoring terminal are all electrically connected to the controller 4. The humidity sensor 2 is used to detect the humidity of the outer wall of the drainage tube and feed back the humidity monitoring result to the controller 4; the color sensor 3 is used to monitor the color of the drainage fluid in the drainage tube and feed back the color monitoring result to the controller 4; the controller 4 is used to transmit the humidity monitoring result and the color monitoring result to the drainage tube monitoring terminal.

[0047] like Figure 1 As shown, the drainage tube monitoring terminal includes a humidity analysis module, a liquid source analysis module, and an anomaly alert module.

[0048] The humidity analysis module is used to acquire humidity monitoring results, analyze whether the humidity of the outer wall of the drainage tube is greater than the preset humidity, and generate a humidity analysis result. The liquid source analysis module is used to acquire an image of the drainage tube area and analyze the liquid flow direction if the humidity analysis result shows that the humidity of the outer wall of the drainage tube is greater than the preset humidity, and generate a liquid source analysis result. The anomaly alert module is used to generate a leakage anomaly alert based on the liquid source analysis result. In this embodiment, an image of a preset area is acquired through an image acquisition device, and the location of the adjustable fixing strap is identified. Taking the location of the adjustable fixing strap as the starting point, the liquid flow direction is identified. If the liquid flow direction shows that the liquid flows through the wound, and the amount of liquid at the wound is greater than the amount of liquid in other areas of the same size along the liquid flow path, it is determined that the liquid originates from the patient's wound; otherwise, a liquid source analysis result indicating that the liquid does not originate from the patient's wound is generated. If the liquid source analysis result indicates that the liquid originates from the patient's wound, a leakage anomaly alert is generated to remind medical staff to handle the situation promptly.

[0049] The drainage tube monitoring terminal also includes a drainage fluid anomaly analysis module, used to analyze color anomalies in the drainage fluid based on color monitoring results and generate a drainage fluid anomaly analysis result; the anomaly alert module is further used to generate a drainage fluid anomaly alert based on the drainage fluid anomaly analysis result. In this embodiment, if the drainage fluid anomaly analysis result shows that the drainage fluid is red, a drainage fluid anomaly alert is generated.

[0050] This solution can provide timely alerts when fluid leaks from the drainage tube, enabling real-time monitoring of abnormal drainage conditions. This facilitates timely dressing changes by medical staff and prevents infection.

[0051] Example 2:

[0052] The basic principle of Example 2 is the same as that of Example 1. The difference is that the drainage tube monitoring terminal in Example 2 also includes a body temperature detection module, which is used to acquire the user's body temperature data based on the humidity analysis results, analyze whether the user's body temperature is abnormal, and generate a body temperature analysis result. The abnormality prompt module is also used to generate a body temperature abnormality prompt based on the body temperature analysis result. In this example, if the body temperature analysis result shows that the user's body temperature data is not within the preset body temperature range, a body temperature abnormality prompt is generated. By adopting this solution, the user's body temperature data is acquired based on the humidity analysis results, so that when abnormalities such as leakage occur in the drainage tube, the patient's physical data can be collected in a timely manner to prompt medical staff going to treat the patient's wound to understand the patient's condition in advance and take appropriate measures.

[0053] Example 3:

[0054] The basic principle of Example 3 is the same as that of Example 1. The difference is that in Example 3, the drainage tube monitoring terminal also includes a patrol time acquisition module, which is used to acquire the current time and the patrol time of medical staff, and generate a monitoring frequency. Specifically, if the time interval between the most recent patrol time of medical staff and the current time is less than 30 minutes, the monitoring frequency is controlled to be once every 5 minutes; if the time interval between the patrol time of medical staff and the current time is greater than or equal to 30 minutes and less than two hours, the monitoring frequency is controlled to be once every 3 minutes; if the time interval between the patrol time of medical staff and the current time is greater than or equal to 2 hours, the monitoring frequency is controlled to be once every 1 minute. The controller 4 controls the data acquisition frequency of the humidity sensor 2 and the color sensor 3 according to the monitoring frequency generated by the patrol time acquisition module.

[0055] Therefore, the monitoring frequency can be adjusted according to actual needs, ensuring timely detection of abnormal situations while reducing system power consumption.

[0056] Example 4:

[0057] The basic principle of Example 4 is the same as that of Example 1. The difference lies in that, in Example 4, the monitoring time acquisition module doubles the monitoring frequency if the current time is between 12:00 AM and 5:00 AM. For example, if the current monitoring frequency is once per minute, it is adjusted to once every 30 seconds. The principle is that patients are more likely to be asleep at this time, and there is a higher possibility that they will unconsciously turn over, causing the drainage tube to shift, which is difficult for both patients and medical staff to detect. Therefore, increasing the monitoring frequency during this period ensures timely detection of abnormalities.

[0058] Example 5:

[0059] The basic principle of Example 5 is the same as that of Example 1. The difference is that in Example 5, a temperature sensor is also provided in the groove 5 of the adjustable fixing band 1, and the temperature sensor is electrically connected to the controller 4.

[0060] The temperature sensor is used to monitor the temperature of the drainage fluid in the drainage tube and to feed back the temperature monitoring results to the controller 4.

[0061] The controller 4 is also used to transmit the temperature monitoring results to the drainage tube monitoring terminal;

[0062] The anomaly alert module is used to generate an anomaly alert for the drainage fluid based on the anomaly analysis results and temperature monitoring results. In this embodiment, if the anomaly analysis results show that the drainage fluid is red and the temperature monitoring results show that the temperature of the drainage fluid is higher than a preset temperature, an arterial bleeding anomaly alert is generated; if the anomaly analysis results show that the drainage fluid is red and the temperature monitoring results show that the temperature of the drainage fluid is lower than or equal to a preset temperature, a non-arterial bleeding anomaly alert is generated.

[0063] The above are merely embodiments of the present invention. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date.

Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention. These should also be considered within the scope of protection of the present invention, and will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
