Description

Technical Field

[0001] The present invention belongs to the field of medical technology, and in particular relates to a drainage device, implementation method and system for AI adaptive analysis. Background Art

[0002] Drainage is the removal of abnormal accumulations of fluid, gas, or pus from the body, surgically or otherwise, to relieve symptoms, promote healing, and prevent complications.

[0003] Drainage can be divided into active drainage and passive drainage. Active drainage usually uses a drainage tube combined with a negative pressure system or gravity, and is widely used in postoperative situations, abscesses, pleural effusions, and peritoneal effusions. There are many types of drainage tubes, including chest drainage tubes, abdominal drainage tubes, and urinary catheters.

[0004] The indications for drainage mainly include infection, effusion, bleeding and gas accumulation. During the drainage process, the aseptic principle must be strictly followed, the amount and nature of the drainage fluid must be monitored regularly to assess changes in the condition, and the drainage tube must be replaced as needed to prevent blockage and infection.

[0005] During the drainage process, a variety of problems may occur, among which drainage tube blockage is a common and important complication, such as blood clot formation, sticky secretions, tube distortion or compression, and deposition on the inner wall of the drainage tube. Blockage can cause fluid accumulation in the body, causing pain, infection and other complications, and may even endanger the patient's life. In addition, blockage weakens the drainage effect and cannot effectively discharge abnormal fluids in the body, which may aggravate the condition or prolong recovery time.

[0006] At present, the clinical detection methods for drainage tube blockage are relatively limited. Common inspection methods such as observing the amount and nature of drainage fluid and listening to the sound of the drainage tube can help determine the patency, but cannot directly and accurately confirm whether the tube is blocked. This lack of effective detection methods makes it more difficult to detect and deal with drainage tube blockage in the early stage, increasing the risk to patients.

[0007] In addition, the patency of the drainage tube will also affect the judgment of the extubation time. If the drainage tube is unobstructed and the liquid or gas can be discharged smoothly, the timing of extubation can usually be judged earlier; on the contrary, if the drainage tube is blocked or obstructed, it may cause fluid retention, thereby delaying the extubation time and affecting the patient's comfort and recovery process.

[0008] Therefore, clinically, medical staff need to regularly check the patency of the drainage tube to ensure that there is no blockage, and make a comprehensive judgment on when it is safe to remove the tube based on the amount and nature of the drainage and the patient's clinical condition.

[0009] Manual inspection may delay the discovery of drainage tube blockage due to heavy workload and long time intervals, thus affecting the patient's recovery and the timing of extubation.

[0010] If drainage tube blockage is not discovered in time, it may lead to misjudgment of the timing of tube removal, delay the patient's treatment and recovery process, and even cause complications. Frequent manual inspections not only consume time, but also increase the workload of medical staff, affecting their attention and energy on other nursing tasks.

[0011] In summary, how to provide a drainage device that is convenient for monitoring the patency of the drainage tube is a technical problem that urgently needs to be solved. Summary of the invention

[0012] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a drainage device, implementation method and system with AI adaptive analysis, which can collect the patency data of the drainage tube after injecting gas or liquid into the drainage tube, and determine the patency of the drainage tube based on the collected results. It can monitor the patency of the drainage tube in real time, discover problems in time, and reduce the frequency, inaccuracy and burden of manual inspection.

[0013] The present invention provides an AI adaptive analysis drainage device, comprising a drainage tube, wherein the drainage tube comprises a front portion corresponding to being inserted below the skin and a rear portion corresponding to being located outside the skin; The rear portion is connected to a two-way gas-liquid control unit, including an extraction structure and an injection structure, wherein the extraction structure is used to perform a suction operation on the drainage tube, and the injection structure is used to inject gas or liquid into the drainage tube; The detection unit is used to collect data on the patency status of the drainage tube; The controller is used to determine the patency of the drainage tube based on the patency status data sent by the detection unit.

[0014] Further, the extraction structure and the injection structure are separately arranged; or, the extraction structure and the injection structure are combined and arranged; The detection unit includes an air pressure sensor, an image acquisition component and / or a flow rate sensor; The detection unit further comprises a timer, and the timer is communicatively connected with the aforementioned controller.

[0015] Furthermore, the front portion is provided with an airbag that can expand and contract to fix the front portion under the skin, and / or the rear portion is movably connected with a fixing structure that can contact the skin and fix the drainage tube on the skin.

[0016] The present invention provides a method for implementing a drainage device using the AI ​​adaptive analysis as described above, comprising the following steps: S1 monitors the drainage process of the drainage tube, and triggers the patency assessment link of the drainage tube when no drainage fluid flows out of the drainage tube; S2 introduces gas or liquid into the rear part of the drainage tube; S3 collects the patency status data of the drainage tube and determines the patency of the drainage tube according to the result.

[0017] Furthermore, before the drainage process of the drainage tube is monitored by S1, the process also includes fixing the rear portion of the drainage tube on the skin and fixing the front portion of the drainage tube under the skin.

[0018] Furthermore, S3 collects the patency status data of the drainage tube, including collecting air pressure data at different positions in the drainage tube, and comparing whether there is a difference between the air pressure data. If there is a difference, it is determined that the drainage tube is not patency; otherwise, it is determined that the drainage tube is patency.

[0019] Further, S3 collects the data of the patency status of the drainage tube, including, after the liquid is introduced, monitoring the flow rate of the liquid in the drainage tube, if the flow rate of the liquid is lower than a preset threshold range, it is determined that the drainage tube is not patency; otherwise, it is determined that the drainage tube is patency; And / or, at least one indicator position is provided on the drainage tube, an image of the drainage tube is collected, and the image is analyzed to see whether the liquid passes through the indicator mark. If the liquid passes through all the indicator marks, the drainage tube is determined to be unobstructed, otherwise it is determined to be blocked.

[0020] Furthermore, after determining the patency of the drainage tube, S3 also includes taking corresponding treatment measures according to the determination result; When the determination result is that the drainage tube is blocked, outputting a prompt; When the determination result is that the drainage tube is unobstructed, gas no greater than the introduced amount is extracted outward, or liquid is extracted outward until liquid no less than the drainage amount is extracted.

[0021] Furthermore, the corresponding treatment measures also include, when the judgment result is that the drainage tube is unobstructed, starting the timing and recording the timing result, and when the timing result reaches a preset threshold, outputting a prompt to stop the drainage.

[0022] The present invention provides a system using any one of the above-mentioned implementation methods, the system comprising: Trigger control module: used to monitor the drainage process of the drainage tube, and trigger the patency status assessment link of the drainage tube when no drainage flow is flowing out of the drainage tube; Evaluation module: used to collect the patency data of the drainage tube after the introduction of gas or liquid, and determine the patency of the drainage tube based on the results.

[0023] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art, as an example: It can automatically trigger the assessment of the patency of the drainage tube when there is no drainage material passing through the drainage tube. Through various detection methods, more accurate assessment results can be obtained, reducing the workload of medical staff who need to regularly manually check the patency of the drainage tube, improving work efficiency and reducing the untimeliness and inaccuracy of manual inspections.

[0024] Different treatment measures can be taken according to the patency of the drainage tube. When the drainage tube is blocked, relevant personnel can be promptly discovered and prompted, which reduces the risk of infection and other complications and improves the overall safety and comfort of the patient. When the drainage tube is unobstructed, the system will automatically start timing and prompt for tube removal when the tube removal criteria are met. The system can scientifically determine the timing for tube removal and ensure that it is removed at the appropriate time, thereby avoiding unnecessary extension of drainage and the risk of infection and complications caused by premature tube removal.

[0025] It is suitable for various types of drainage tubes, such as chest, abdominal, and urinary catheters, and has broad clinical application prospects. It can reduce unnecessary drainage time and hospitalization days, optimize hospital resource allocation, reduce medical costs, and improve the utilization efficiency of medical resources.

DETAILED DESCRIPTION

[0031] The technical solution disclosed in the present invention is described in detail below in conjunction with specific embodiments.

[0032] Techniques and methods known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques and methods should be considered part of the specification. In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0033] The present invention provides a drainage device 100 with AI adaptive analysis.

[0034] like Figure 1-3 As shown, the drainage tube 200 includes a front portion 210 corresponding to being inserted under the skin and a rear portion 220 corresponding to being located outside the skin.

[0035] The rear portion 220 is connected to a bidirectional gas-liquid control unit 300, including an extraction structure 310, and the extraction structure 310 is used to perform a suction operation on the drainage tube 200, and can extract the contents in the drainage tube 200, and the contents include gas, liquid, solid, and a solid-liquid mixture.

[0036] The extraction structure 310 may be a negative pressure suction device, such as a negative pressure drainer, which can effectively extract the drainage tube 200 by generating negative pressure.

[0037] Another option is an electric suction pump, which provides adjustable suction rate and pressure, suitable for situations where continuous drainage is required or larger volumes of fluid are handled. In addition, manual suction devices can also be a simple and effective option that is easy to operate in a clinical environment.

[0038] Of course, you can also use a manual suction pump, which is suitable for simple drainage needs and is easy to operate and carry.

[0039] Optionally, a filter or screen is used in conjunction to prevent blood clots or other particulate matter from entering the extraction structure 310, thereby reducing the risk of clogging.

[0040] The contents extracted by the extraction structure 310 can be introduced into a waste bin to await subsequent processing.

[0041] The bidirectional gas-liquid control unit 300 further includes an injection structure 320 , and the injection structure 320 is used to inject gas or liquid into the drainage tube 200 .

[0042] The injection structure 320 can have different options depending on the injected material. For example, when the injected material is gas, the injection structure 320 can use an air pump to control the flow rate and pressure of the gas while ensuring that the gas is injected into the drainage tube 200 safely and effectively.

[0043] When the infusion is liquid, the injection structure 320 can use a liquid injection pump or a liquid infusion device to provide a stable liquid flow rate to ensure uniform distribution and rapid injection of the liquid in the drainage tube 200. It can also be further equipped with a backflow prevention component to prevent the liquid from flowing back to the injection source.

[0044] The extraction structure 310 and the injection structure 320 are separately arranged. Figure 1 shown.

[0045] Alternatively, the extraction structure 310 and the injection structure 320 are combined and arranged, such as Figure 2 As shown, that is, it has the functions of injecting gas and injecting liquid at the same time.

[0046] like Figure 1 and 2 As shown, the detection unit 400 is used to collect data on the patency status of the drainage tube 200 .

[0047] The detection unit 400 includes an air pressure sensor, an image acquisition component and / or a flow rate sensor.

[0048] The detection unit 400 further includes a timer, and the timer is signal-connected to the controller.

[0049] like Figure 3 As shown, the front part 210 is provided with an airbag 500 that can expand and contract. After the front part 210 enters under the skin, the airbag 500 also enters under the skin. Depending on the drainage site, different human tissues may be distributed around the airbag 500, including bones, blood vessels, organs, fat, muscles, connective tissues, etc.

[0050] There is a gap between the front part 210 and the surrounding human tissues, and the airbag 500 expands or contracts to fill the gap, so that the front part 210 is more firmly fixed to the surrounding human tissues, and the front part 210 is limited to prevent it from shifting in the body.

[0051] Furthermore, the airbag 500 is configured to be relatively small and soft. When inflated, the pressure is effectively dispersed by controlling the speed and degree of inflation, thereby reducing direct pressure on surrounding tissues and reducing the patient's discomfort and potential risk of injury.

[0052] The rear portion 220 is movably connected with a fixing structure 600 , and the fixing structure 600 can contact the skin and fix the drainage tube 200 on the skin.

[0053] As an example, Figure 3As shown, the fixing structure 600 includes a thread 221 disposed on the rear portion 220 , and the thread 221 is disposed at a position close to the connection between the rear portion 220 and the front portion 210 , close to the skin.

[0054] The fixing structure 600 also includes a fastener that can be movably connected to the rear part 220. The fastener has openings at both ends, an inner diameter slightly larger than the rear part 220, and can move on the rear part 220. A thread 221 is correspondingly arranged on the inner side of the opening of the fastener close to the thread 221. The thread 221 engages with the fastener so that the fastener can be connected to the thread 221 of the rear part 220, thereby reinforcing the connection between the rear part 220 and the skin.

[0055] In another embodiment, the fixing structure 600 includes a snap-fit ​​device (not shown in the figure) arranged at the rear portion 220, including a movable clip that can be fixed in a groove of the rear portion 220 of the drainage tube 200 after being pressed, and the elasticity of the snap-fit ​​is used to provide a fixing force to fix the rear portion 220 of the drainage tube 200 on the skin.

[0056] In another embodiment, the fixing structure 600 fixes the rear portion 220 by magnetism. For example, a small magnet (not shown in the figure) is disposed on the rear portion 220 of the drainage tube 200 and the skin contact surface.

[0057] Other options include spring fixation, adhesive fixation, clamping fixation, sliding locking fixation, etc.

[0058] The present invention provides an analysis method of a drainage device 100 using the AI ​​adaptive analysis described above, such as Figure 4 As shown, the following steps are included: S1 monitors the drainage process of the drainage tube 200 , and triggers a patency status assessment link of the drainage tube 200 when no drainage fluid flows out of the drainage tube 200 .

[0059] When no drainage flows out of the drainage tube 200, there are two situations: one, the drainage tube 200 is unobstructed, but the existing drainage in the body has been completely discharged, and no new drainage is produced temporarily. This situation is common after certain medical operations, such as post-operative drainage. As time goes by, the fluid or secretion in the body is gradually discharged, but no new drainage is produced temporarily due to wound healing or other factors.

[0060] Second, the existing drainage material in the body has not been completely discharged, but the drainage tube 200 is blocked and thus cannot be further discharged.

[0061] The triggering of the patency status assessment link of the drainage tube 200 can be achieved in the following two ways: First, manually observe whether there is drainage flow out of the drainage tube 200. If a waste bin is set up, it can be observed whether there is new drainage material entering the waste bin. If no new drainage material passes through the drainage tube 200 for a period of time and enters the waste bin, the patency status assessment link of the drainage tube 200 can be manually triggered by a set button or remote control.

[0062] Secondly, detection is performed through the detection unit 400, and the unobstructed state evaluation link is automatically triggered according to the detection result.

[0063] For example, a flow sensor can detect the flow of fluid and record the flow rate. When the flow is detected to be zero within a set time, such as 5 minutes, the unobstructed state assessment link is automatically triggered.

[0064] For another example, the image acquisition component acquires images of various locations of the drainage tube 200 , for example, by setting a timed task to acquire images regularly, for example, every several seconds or minutes, so as to analyze the state changes in different time periods.

[0065] The images are analyzed to determine whether there is any content passing through the drainage tube 200 in different time periods.

[0066] When the drainage tube 200 itself is transparent, the color of the contents is quite different from that of the drainage tube 200 itself. By setting a color difference threshold, if the detected color difference exceeds the value, it is considered that there are contents in the tube. Otherwise, there are no contents.

[0067] If no contents are detected in multiple consecutive image frames within a set time period, the patency status assessment link is automatically triggered by the preset threshold condition.

[0068] S2 introduces gas or liquid into the rear portion 220 of the drainage tube 200 .

[0069] When gas is introduced, a relatively small amount of gas is usually injected into the rear portion 220 of the drainage tube 200 to reduce the impact on the human body and collect data on the patency status of the drainage tube 200 .

[0070] When the drainage tube 200 is unobstructed, after the gas enters the rear portion 220 of the drainage tube 200, it will follow the drainage tube 200 to the front portion 210 of the drainage tube 200, and the gas will quickly spread along the pipe, and the air pressure in the drainage tube 200 will rise slightly. This is because the number of gas molecules in the tube increases, causing the local air pressure to rise, and it tends to balance in a short time, and the difference in air pressure before and after is relatively small.

[0071] The gas will then continue to flow forward and eventually be discharged through the front portion 210 of the drainage tube 200. The gas pressure will gradually return to its original level, or remain in a state slightly higher than the original level under certain conditions.

[0072] If the drainage tube 200 is partially blocked or obstructed, the gas may not be able to move forward smoothly after being introduced, resulting in a significant increase in air pressure at the rear 220. The gas may accumulate behind the obstruction point, resulting in an increase in air pressure behind the obstruction point, while the air pressure in front of the obstruction point may remain relatively low. If there is a difference in air pressure before and after the drainage tube 200, it means that the drainage tube 200 is obstructed. The boundary area where there is a difference in air pressure before and after can be used to determine the obstruction position of the drainage tube 200, and then infer the specific location and possible width of the obstruction.

[0073] Several air pressure sensors are provided to collect air pressure data at different positions in the drainage tube 200 as patency data, and the air pressure data are compared to see if there are differences. The patency of the drainage tube 200 is determined based on the results.

[0074] If it exists, it is determined that the drainage tube 200 is blocked; otherwise, it is determined that the drainage tube 200 is unobstructed.

[0075] In addition to judging patency by introducing gas, patency can also be judged by introducing liquid. The liquid here mainly refers to infusion liquids and physiological liquids including physiological saline, glucose solution, lactated Ringer's solution, etc., which can be safely used in the human body.

[0076] When the drainage tube 200 is unobstructed, after the liquid enters the rear portion 220 of the drainage tube 200 , it will flow along the drainage tube 200 to the front portion 210 of the drainage tube 200 .

[0077] The flow rate of a liquid is affected by many factors.

[0078] When the liquid flows, it will experience the friction resistance of the inner wall of the pipe and the viscosity resistance of the fluid itself. In addition, the diameter, length and curvature of the drainage tube 200, the viscosity and fluidity of the liquid, etc., all of which will cause the flow rate to gradually decrease in the pipe.

[0079] In addition, the relative height of the discharge end of the drainage tube 200 and the liquid inlet end must also be considered.

[0080] When the discharge end of the drainage tube 200 is lower than the liquid inlet end, the flow rate of the liquid will increase under the action of gravity and pressure difference, offsetting the resistance caused by friction and viscosity to a certain extent, thereby increasing the overall flow rate until the liquid enters the human body through the front part 210 of the drainage tube 200.

[0081] When the discharge end of the drainage tube 200 is higher than the liquid inlet end, the liquid flow rate will be significantly reduced compared to when it enters the tube due to the combined effects of pressure difference, gravity, and other factors affecting the flow rate mentioned above.

[0082] In either case, when the drainage tube 200 is unobstructed, the liquid is in a flowing state in the drainage tube 200 and the flow rate can be measured by the flow rate sensor.

[0083] When the drainage tube 200 is blocked, after the liquid enters the rear portion 220 of the drainage tube 200 , the flow rate of the liquid in the tube will be significantly slowed down due to the presence of the obstruction. When the drainage tube 200 is completely blocked, the flow may even stop completely.

[0084] The flow rate data of the liquid entering the drainage tube 200 is collected by the flow rate sensor as the unobstructed state data. The collected result is compared with the preset liquid flow rate threshold range, and the preset threshold unit corresponds to the flow rate range of the liquid when the drainage tube 200 is unobstructed. If the liquid flow rate is within the preset threshold range, it is determined that the drainage tube 200 is unobstructed. On the contrary, if the liquid flow rate is lower than the preset threshold range, it is determined that the drainage tube 200 is not unobstructed.

[0085] In another embodiment, an indicator mark 230 is disposed on the drainage tube 200, as shown in the figure. For example, a plurality of indicator marks 230 are disposed at different positions of the front portion 210 and the rear portion 220 of the drainage tube 200, and are spaced a certain distance apart from each other.

[0086] The indicator mark 230 may have a different color from the drainage tube 200 for easy identification.

[0087] The image of the drainage tube 200 is acquired by the image acquisition component.

[0088] The image of the rear portion 220 of the drainage tube 200 can be acquired by an image acquisition component that is set on the drainage tube 200, or is not set on the drainage tube 200, but is set around the drainage tube 200, while the image of the front portion 210 of the drainage tube 200 inserted below the skin can be acquired using endoscopic technology or a special optical sensor. These devices can enter the body through the channel where the drainage tube 200 is inserted, providing a more direct perspective to help observe the fluid flow and possible obstacles inside the tube.

[0089] Analyzing the collected images to determine whether the liquid has passed through the indicator marks 230 set at various locations generally includes the following steps: The image is preprocessed including denoising and normalization, and then the position of the indicator mark 230 is identified by features such as color and shape.

[0090] In the case where the liquid has color, the characteristic color can be extracted and color segmentation can be performed to obtain the position of the liquid in the pipeline, which can be compared with the position of the indicator mark 230 to determine whether the liquid reaches the position of the indicator mark 230.

[0091] If the liquid itself is colorless and transparent, first establish the background model without the liquid.

[0092] Because transparent liquids may cause changes in the refraction of light in the pipe, the presence of liquid can be identified by analyzing changes in brightness and contrast in the image.

[0093] For example, the drainage tube 200 can be placed under different lighting conditions by setting a lighting component, and images can be collected. The previously established background model can be compared with the images collected under different lighting conditions, the brightness distribution can be observed, and the location of the liquid can be identified.

[0094] The above image analysis technologies are all part of the existing technology and will not be described in detail again.

[0095] In a specific implementation, the data of the flow sensor can be combined to assist in confirming whether the liquid passes through the indicator mark 230 .

[0096] If it is found after analysis that the liquid passes through all the indicator marks 230, it is determined that the drainage tube 200 is unobstructed, otherwise it is determined that it is blocked.

[0097] S3 also includes, after determining the patency of the drainage tube 200 , taking corresponding treatment measures according to the determination result.

[0098] When the determination result is that the drainage tube 200 is blocked, a prompt is output.

[0099] The form of output and the format of the prompt are not limited, and are taken as an example rather than a limitation. For example, an alarm may be set to output a sound and / or flashing light, etc.

[0100] Alternatively, a text prompt is output via a display screen.

[0101] When the determination result is that the drainage tube 200 is unobstructed, the two-way gas-liquid control unit 300 extracts gas no greater than the introduced amount to the outside, and extracts the gas introduced into the drainage tube 200 that may enter the human body.

[0102] Alternatively, the liquid is extracted outwards until a liquid not less than the drainage amount is extracted, and the liquid introduced into the drainage tube 200 and entering the human body is extracted.

[0103] The corresponding treatment measures also include, when the judgment result is that the drainage tube 200 is unobstructed, starting the timing and recording the timing result, and when the timing result reaches a preset threshold, outputting a prompt to stop drainage.

[0104] As an example, the preset threshold is set to 12-24 hours. That is, if the drainage tube 200 is unobstructed and no new drainage material is discharged within 12-24 hours, the operation of removing the drainage tube 200 can be performed.

[0105] The output prompt format can refer to the above description.

[0106] The present invention provides an analysis system using any one of the above analysis methods, the system comprising: A trigger control module is used to monitor the drainage process of the drainage tube 200, and trigger the patency status assessment link of the drainage tube 200 when no drainage flows out of the drainage tube 200; Evaluation module: used to collect the patency data of the drainage tube 200 after the introduction of gas or liquid, and determine the patency of the drainage tube 200 according to the results.
