Description

Technical fields:

[0001] This invention relates to the field of medical device technology, specifically a high-efficiency negative pressure irrigation and drainage system. This system combines negative pressure drainage and irrigation technologies, aiming to provide a device that can efficiently and safely treat wounds. It is suitable for various medical scenarios requiring irrigation and drainage, such as postoperative wound management, chronic wound treatment, and burn treatment. Background technology:

[0002] 1. Development of negative pressure drainage technology:

[0003] Negative pressure wound therapy (NPWT) is an advanced wound care technique. Its principle involves creating a closed space on the wound surface and applying uniform negative pressure suction, using the mechanical action of negative pressure to promote wound healing. This technique not only accelerates blood circulation in the wound but also effectively removes exudate, bacteria, and necrotic tissue, thereby reducing the risk of infection and promoting granulation tissue growth and wound healing.

[0004] 2. Application of irrigation techniques in wound treatment:

[0005] Irrigation is a crucial step in wound care. By injecting irrigation fluid into the wound, dirt and bacteria on the wound surface can be removed, reducing the risk of infection. Simultaneously, the irrigation fluid also removes exudate and necrotic tissue from the wound, providing a cleaner environment for healing.

[0006] 3. Limitations of existing technology:

[0007] While both negative pressure drainage and irrigation techniques offer significant advantages in wound management, existing negative pressure drainage and irrigation devices are often independent, lacking integrated design and intelligent control. This necessitates that healthcare professionals operate two separate devices, increasing operational complexity and potentially impacting treatment effectiveness and safety.

[0008] 4. The proposal of a high-efficiency negative pressure flushing and drainage system:

[0009] To address the limitations of existing technologies, this invention proposes a highly efficient negative pressure irrigation and drainage system. This system combines negative pressure drainage and irrigation technologies, achieving simultaneous irrigation and drainage through an integrated design and intelligent control. This design not only simplifies the operation process but also improves treatment efficacy and safety.

[0010] In summary, the proposed high-efficiency negative pressure irrigation and drainage system aims to address the shortcomings of existing wound care equipment in terms of operational complexity, treatment effectiveness, and safety. By combining the advantages of negative pressure drainage and irrigation technologies, this system provides healthcare professionals with a more efficient, safe, and convenient wound care solution. Summary of the Invention:

[0011] This invention proposes a high-efficiency negative pressure irrigation and drainage system, specifically designed for medical settings. Combining negative pressure drainage and irrigation technologies, it aims to treat wounds efficiently and safely. The system features an integrated design, with a central lumen and edge sandwich structure within the negative pressure irrigation and drainage tube, equipped with multiple irrigation ports to achieve simultaneous irrigation and drainage. The system has intelligent control capabilities, automatically adjusting the irrigation strategy based on the volume and properties of the irrigation and drainage fluid, improving treatment effectiveness and safety. Simultaneously, it supports alternating or simultaneous suction from multiple drainage tubes, reducing the risk of cross-infection. Furthermore, the system integrates data synchronization, information display, and alarm functions, enhancing the informatization level of medical services. This system simplifies the operation process, providing medical staff with an efficient and convenient wound treatment solution.

[0012] Preferably, a high-efficiency negative pressure flushing and drainage system is provided, wherein the negative pressure flushing and drainage tube adopts a central cavity and an edge sandwich structure, and multiple side holes are provided around the central cavity, and the side holes pass through the edge sandwich to communicate directly with the external environment;

[0013] The edge interlayer structure of the negative pressure flushing drainage tube is also designed with a first channel flushing hole.

[0014] The first channel flushing hole is an opening on the outside of the drainage tube interlayer, and the opening does not directly enter the central cavity of the drainage tube; the first channel flushing hole is connected to the external first channel flushing pipe through the edge interlayer structure.

[0015] Preferably, in a high-efficiency negative pressure flushing and drainage system, the negative pressure flushing and drainage tube further includes a second flushing channel;

[0016] The second flushing port, like the first flushing port, is located in the edge sandwich structure, forming an opening on the outside of the drainage tube sandwich, not directly into the central lumen of the drainage tube. The second flushing port connects to the external second flushing pipe through the edge sandwich structure, allowing medical personnel to flush the drainage cavity and the drainage tube itself through two independent flushing channels, improving flushing efficiency and flexibility. Simultaneously, one channel can be used for flushing while the other is used for medication administration.

[0017] Preferably, a high-efficiency negative pressure irrigation and drainage system is characterized by having multiple drainage tube interfaces and irrigation tube interfaces to flexibly adapt to the needs of using single or multiple negative pressure irrigation and drainage tubes, and to suit different wound conditions. When configured with multiple negative pressure irrigation and drainage tubes, the system can achieve alternating or simultaneous suction from multiple tubes, improving drainage efficiency. Furthermore, the drainage tube performing the suction operation is not necessarily the one currently undergoing irrigation; this design helps to better maintain sponge cleanliness, reduce the risk of cross-infection, and further improve the safety and effectiveness of treatment.

[0018] Preferably, a high-efficiency negative pressure flushing and drainage system is characterized by further including a function that automatically adjusts the flushing strategy based on the amount of flushing fluid and the amount of drainage fluid:

[0019] The following are the specific implementation methods:

[0020] Step 1: System Initialization and Parameter Settings

[0021] Start the high-efficiency negative pressure flushing and drainage system to ensure that all components (including flushing fluid speed control device, negative pressure device, drainage tube, etc.) are in normal working condition;

[0022] Based on the patient's wound condition, drainage needs, and the doctor's instructions, set the initial irrigation fluid rate and negative pressure value on the control device. Typically, the initial irrigation fluid rate should be set to a low flow rate to avoid excessive impact on the wound; Step 2: Begin low-flow irrigation.

[0023] The irrigation fluid speed control device is activated, and the wound is irrigated at the set initial low flow rate.

[0024] The monitoring device observes the rate of change in the drainage fluid in real time and compares it with the rate of the flushing fluid.

[0025] Step 3: Determine and adjust the flushing fluid rate

[0026] When the system detects that the drainage volume is comparable to the current irrigation volume, it should automatically or gradually increase the irrigation rate according to the doctor's instructions.

[0027] The adjustment process should be gradual, and the rate of increase each time should be controlled within a certain range to avoid sudden changes in flow that could adversely affect the wound.

[0028] During the adjustment process, the volume of drainage fluid and flushing fluid should be continuously monitored to ensure that the two are kept in dynamic balance.

[0029] Step 4: Prevent rinsing fluid from overflowing.

[0030] As the flushing fluid velocity increases, close attention should be paid to any overflow of the flushing fluid.

[0031] If the flushing fluid volume is found to be greater than the drainage fluid volume, the flushing fluid rate should be stopped immediately and the flow rate reduced appropriately to prevent flushing fluid overflow.

[0032] Step 5: Security and Protection Mechanisms

[0033] The system should be equipped with an overflow warning device. When an overflow trend of the flushing fluid is detected, an alarm should be issued immediately and the flushing fluid rate should be automatically reduced.

[0034] In the event of a system malfunction or severe overflow of irrigation fluid, the emergency shutdown device should be activated quickly to protect patient safety; Step 6: Recording and Feedback

[0035] Throughout the rinsing process, key parameters such as rinsing fluid volume, drainage fluid volume, rinsing speed, and rinsing time should be recorded. Based on the recorded data, the rinsing effect should be evaluated, and the rinsing fluid speed control device should be adjusted and optimized according to the evaluation results.

[0036] Preferably, a high-efficiency negative pressure flushing and drainage system is characterized by further including a function to automatically adjust the flushing strategy according to the properties of the drainage fluid;

[0037] The specific method is as follows:

[0038] Step 1: Detect the properties of the drainage fluid

[0039] Drainage fluid property analysis is a crucial method for assessing wound condition. This step involves using an irrigation fluid property analysis system that integrates various advanced technologies, such as optical analysis, electrochemical sensing, and biomolecular recognition. These technologies can monitor multiple key indicators in the drainage fluid in real time, such as protein concentration, cell type, and pH value. This data provides physicians with a clear picture of wound inflammation, infection, and healing status, forming the basis for developing precise treatment plans.

[0040] Step 2: Flush Strategy Formulation and Optimization

[0041] Based on the results of the drainage fluid property analysis in step 1, doctors can develop personalized irrigation strategies. This includes selecting appropriate irrigation fluid types (such as saline, antibiotic solutions, etc.), concentrations, and irrigation frequencies to meet the treatment needs of different wounds. Furthermore, the system has intelligent optimization capabilities. During treatment, the system continuously collects and analyzes relevant data on the drainage and irrigation fluids, automatically adjusting the irrigation strategy to ensure the effectiveness and safety of the treatment. This dynamic adjustment capability makes treatment more flexible and personalized.

[0042] Step 3: Monitoring and Adjusting the Rinsing Process

[0043] During the irrigation process, the system monitors key parameters such as the properties of the drainage fluid, the irrigation fluid flow rate, and the negative pressure environment in real time to ensure the stability and accuracy of the process. When the system detects abnormalities, such as abnormal irrigation fluid flow rate or unstable negative pressure, it immediately issues an alarm and automatically adjusts the irrigation strategy to avoid adverse effects on the patient. Simultaneously, doctors can view various data points during the irrigation process in real time through the system interface, such as the properties of the drainage fluid, the irrigation fluid flow rate, and the negative pressure value, allowing for manual adjustments at any time. This real-time monitoring and adjustment capability ensures the flexibility and controllability of the treatment process.

[0044] Step 4: Data Analysis and Feedback

[0045] After the irrigation treatment is completed, the system performs a comprehensive analysis and summary of the data from the entire treatment process. This includes trends in the properties of the drainage fluid, records of adjustments to the irrigation strategy, and evaluation of the treatment effect. These data analyses provide doctors with strong data support, helping them better understand the progress of wound treatment and any existing problems, thereby further optimizing treatment plans. Furthermore, the system can also feed this data back to the management departments of research institutions or medical facilities to improve the irrigation fluid property detection system and the methods for developing irrigation strategies, ultimately enhancing the level of wound treatment.

[0046] Preferably, a high-efficiency negative pressure flushing and drainage system is characterized in that,

[0047] It also includes a function to automatically adjust the rinsing strategy based on the user-defined negative pressure sponge specifications;

[0048] The specific steps are as follows:

[0049] Step 1: User enters negative pressure sponge specifications: The user enters detailed specifications of the negative pressure sponge through the system interface, including but not limited to dimensions (such as length, width, and thickness) and material type (such as polyurethane, polyvinyl alcohol, etc.).

[0050] Step 2: The system receives and parses the specification information: The system receives the negative pressure sponge specification information input by the user and parses it using the built-in algorithm or database. Based on the sponge's liquid absorption capacity and permeability, it makes a preliminary judgment on the initial volume and speed of each rinse.

[0051] Step 3: Automatically set the flushing strategy: Based on the judgment results of Step 2, the system automatically adjusts the intelligent flushing fluid speed control device, presets the initial flushing speed and flushing volume, so as to ensure that the flushing process can meet the drainage needs while avoiding discomfort or waste of resources caused by excessive flushing;

[0052] Step 4: Real-time monitoring and dynamic adjustment: During the flushing process, the system continuously monitors the speed and volume of the drainage fluid through a high-precision monitoring module. Combined with real-time data, the system uses intelligent algorithms to dynamically adjust the speed of the flushing fluid to ensure the optimal flushing effect while maintaining the stability and safety of the negative pressure system.

[0053] Step 5: Feedback and Optimization: The system records key parameters and effects during each flushing process, and continuously optimizes the flushing strategy through data analysis to provide more accurate and personalized suggestions for future treatments.

[0054] Preferably, a high-efficiency negative pressure flushing and drainage system is characterized by further including a data synchronization system and an information display and alarm system:

[0055] The data synchronization system features a standardized interface that connects to the Hospital Information System (HIS) for bidirectional data transmission. The system automatically retrieves relevant patient parameters from the HIS, such as age, gender, and medical history, providing data support for personalized settings of the negative pressure system. Simultaneously, the system synchronizes treatment data recorded by the negative pressure system, including drainage volume, irrigation volume, irrigation fluid rate, and negative pressure value, to the HIS in real time, facilitating access and analysis by medical staff and improving the informatization level of medical services.

[0056] The information display and alarm system provides an intuitive and user-friendly interface, supporting touch operation and multiple language displays, allowing medical staff to quickly learn and familiarize themselves with the operating procedures. Simultaneously, the system has an abnormal alarm function; when the negative pressure value is abnormal, the drainage fluid properties are abnormal, or equipment malfunctions, it can automatically issue an alarm to ensure the safety and continuity of the treatment process.

[0057] Preferably, an integrated high-efficiency negative pressure irrigation and drainage system and its supporting negative pressure control system are characterized by further including an automatic drug injection function after irrigation is completed, in order to optimize the negative pressure treatment effect. Specific steps include:

[0058] Step 1: The system sets the cycle and time for automatic drug injection: Users set the cycle (e.g., daily, every other day) and specific time (e.g., morning, afternoon) for automatic drug injection through the system interface. The system saves the drug injection plan according to the user's settings.

[0059] Step 2: Drug Preparation and Storage: The system is equipped with drug storage units. Users must place the designated drugs in the storage units in advance and ensure the expiration dates and correctness of the drugs. The system can automatically identify the drug type and verify whether the drug situation in the storage units meets the requirements of the injection plan.

[0060] Step 3: Automatic Medication Injection After Rinsing: After one rinsing cycle, the system automatically injects the designated medication into the negative pressure sponge or wound area through the rinsing pipeline according to the preset injection plan. The system precisely controls the injection speed and volume to ensure even distribution of the medication and achieve optimal results.

[0061] Step 4: Real-time Monitoring and Feedback: During the drug infusion process, the system continuously monitors the infusion status, including whether there are any abnormalities in the infusion rate, volume, and pressure (such as pipe blockage, drug leakage, etc.). Once an abnormality occurs, the system immediately issues an alarm and stops the infusion process to ensure patient safety and treatment effectiveness;

[0062] Step 5: Recording and Analysis: The system automatically records detailed parameters and effects of each drug injection, including injection time, drug type, injection volume, etc., and evaluates the impact of drug injection on the effect of negative pressure therapy through data analysis, providing optimization suggestions for future treatment.

[0063] Preferably, a high-efficiency negative pressure flushing and drainage system is characterized by further including a function to automatically adjust the flushing strategy according to the velocity of the flushing fluid and the velocity of the drainage fluid, specifically including the following steps:

[0064] Step 1: Real-time monitoring data acquisition

[0065] The system uses high-precision sensors to monitor and record the rates of the flushing fluid and drainage fluid in real time, ensuring data accuracy and real-time performance. This data forms the basis for subsequent automatic adjustments to the flushing strategy.

[0066] Step 2: Data Analysis and Comparison

[0067] The system analyzes and compares the real-time monitored flushing fluid velocity and drainage fluid velocity to evaluate the effectiveness of the current flushing strategy. By comparing the differences between the two, the system can determine whether the flushing strategy needs to be adjusted to optimize the flushing effect; Step 3: Automatic adjustment of flushing strategy.

[0068] Based on the data analysis and comparison results from step 2, the system can automatically adjust the irrigation strategy. If the irrigation fluid rate is too fast or the drainage fluid rate is too slow, the system will reduce the irrigation fluid rate to avoid excessive pressure on the wound and overflow of the irrigation fluid; if the irrigation fluid rate is too slow or the drainage fluid rate is too fast, the system will increase the irrigation fluid rate to ensure that the wound is adequately irrigated.

[0069] Step 4: Monitoring the Effects of Strategy Adjustments

[0070] After adjusting the flushing strategy, the system continues to monitor the flushing fluid rate and drainage fluid rate in real time to evaluate the effectiveness of the adjusted strategy. If the adjusted strategy still fails to achieve the expected flushing effect, the system will repeat steps 2 and 3 until the optimal flushing strategy is found.

[0071] Step 5: Recording and Feedback

[0072] The system records key parameters and strategy adjustments during each irrigation process, including irrigation fluid velocity, drainage fluid velocity, and irrigation strategy adjustment time. This data can be used for subsequent analysis and optimization, providing more precise and personalized recommendations for future treatments.

[0073] Step 6: Security and Protection Mechanisms

[0074] During the automatic adjustment of the flushing strategy, the system should be equipped with appropriate safety and protection mechanisms. For example, when an abnormal flushing fluid rate or drainage fluid rate is detected, the system should immediately issue an alarm and take appropriate protective measures, such as stopping flushing or adjusting the negative pressure level, to ensure patient safety.

[0075] Preferably, the specific interpretation of the expected effect and the improvement of related steps can be carried out as follows:

[0076] Step 1: Review the preset goals and standards

[0077] Re-examine and clarify the expected irrigation effect targets, including specific indicators such as drainage fluid clarity, drainage fluid volume stability, and wound healing speed;

[0078] Compare the actual data under the current flushing strategy with the preset targets to identify the gaps;

[0079] Step 2: In-depth analysis of the reasons

[0080] Analyze key parameters such as flushing fluid velocity, drainage fluid velocity, flushing fluid type, and negative pressure level to identify the specific reasons that may lead to poor flushing results;

[0081] Consider individual patient differences, such as age, underlying diseases, wound type, and external factors that may affect the irrigation effect;

[0082] Step 3: Assess the patient's condition

[0083] Conduct a comprehensive physical examination and wound assessment on the patient to understand the degree of inflammation, healing stage, and potential complications of the wound; communicate with the patient to understand their subjective feelings, such as pain, itching, discomfort, etc., as well as possible allergy history or drug reaction;

[0084] Step 4: Adjust the rinsing strategy

[0085] Based on the analysis results and the patient's condition, the irrigation strategy will be adjusted again. This may include changing the irrigation fluid rate, adjusting the negative pressure level, changing the type of irrigation fluid, or adding adjuvant medications.

[0086] Ensure the adjusted strategy is suitable for the patient's actual condition and effectively promotes wound healing and improves irrigation results; Step 5: Implement the new strategy and monitor.

[0087] Under the adjusted flushing strategy, the flushing process was restarted, and key data such as flushing fluid rate, drainage fluid rate, and drainage fluid composition were monitored in real time.

[0088] Record key parameters and patient responses during each flushing process for subsequent analysis and evaluation;

[0089] Step 6: Regular evaluation and feedback

[0090] Establish a reasonable evaluation cycle, such as conducting evaluations daily, every two days, or weekly, to ensure that problems are identified and adjustments are made in a timely manner;

[0091] Based on the assessment results and patient feedback, the flushing strategy is adjusted regularly until the expected flushing effect is achieved;

[0092] Step 7: Recording and Analysis

[0093] Record in detail the process, reasons, results, and patient responses for each adjustment to the flushing strategy;

[0094] By conducting in-depth analysis of the recorded data, we can identify potential patterns and influencing factors that lead to poor flushing results, and provide more accurate and personalized recommendations for future treatments. Detailed implementation method:

[0095] A high-efficiency negative pressure flushing and drainage system is characterized by comprising a negative pressure flushing and drainage tube and a matching negative pressure system; the matching negative pressure system includes a drainage fluid volume recorder, a flushing fluid volume recorder, a flushing fluid speed control device, and a negative pressure control device.

[0096] Both the drainage fluid volume recorder and the flushing fluid volume recorder use high-precision sensors to monitor and record relevant data in real time; the flushing fluid speed control device is used to precisely control the flushing speed of the flushing fluid to ensure that the flushing process is both effective and safe.

[0097] I. System Composition

[0098] Negative pressure flushing drainage tube:

[0099] Designed as a tube that can be inserted into the wound and negative pressure sponge, it has dual functions of irrigation and drainage;

[0100] The tubing material should have good biocompatibility and corrosion resistance to ensure the safety and effectiveness of the treatment process.

[0101] Supporting negative pressure system:

[0102] Drainage fluid volume recorder: It uses a high-precision sensor to monitor and record drainage fluid data in real time, providing medical staff with accurate flow information;

[0103] Fluid volume recorder: It also uses a high-precision sensor to monitor and record the flushing fluid data in real time to ensure precise control of the flushing process;

[0104] Irrigation fluid rate control device: Used to precisely adjust the rate of irrigation fluid to meet the treatment needs of different wounds. This device should have stable performance to ensure the continuity and safety of the irrigation process.

[0105] Negative pressure control device: Employing a closed-loop feedback control system, it can accurately maintain the set negative pressure level. By monitoring the negative pressure value in real time and adjusting the output of the negative pressure source as needed, it ensures the effectiveness and stability of negative pressure flushing and drainage.

[0106] II. Implementation Steps

[0107] System preparation:

[0108] Check that the negative pressure flushing drainage pipe is intact and ensure that the pipe connection is tight and there are no leaks.

[0109] Wound treatment:

[0110] Thoroughly clean the wound to remove necrotic tissue and foreign objects;

[0111] Insert the negative pressure irrigation and drainage tube into the wound and / or a negative pressure sponge, ensuring that the tube fits tightly against the wound.

[0112] The specific method depends on the condition of the wound. If there are cavities or sinuses, a negative pressure irrigation and drainage tube can be placed in them.

[0113] Setting parameters:

[0114] Set the appropriate irrigation fluid speed and negative pressure level according to the size and depth of the wound.

[0115] Turn on the drainage fluid volume recorder and the flushing fluid volume recorder to start real-time monitoring and recording of relevant data.

[0116] Start treatment:

[0117] Turn on the irrigation fluid speed control device to begin rinsing the wound.

[0118] Observe the color and characteristics of the drainage fluid, and notify medical staff immediately if any abnormalities are found.

[0119] Adjust the irrigation fluid rate and negative pressure level according to treatment needs.

[0120] End of treatment:

[0121] Turn off the flushing fluid speed control device and the negative pressure control device;

[0122] Remove the negative pressure irrigation drainage tube, disinfect and bandage the wound;

[0123] Organize the system equipment and record relevant data during the treatment process for subsequent analysis.

[0124] A high-efficiency negative pressure irrigation and drainage system is disclosed, which is particularly suitable for wound irrigation and drainage after surgery, as well as for scenarios requiring continuous negative pressure suction therapy. The system mainly consists of a negative pressure irrigation and drainage tube and its matching connecting pipes.

[0125] Negative pressure flushing drainage tube structure design

[0126] Tube Structure: The negative pressure irrigation drainage tube features a unique central lumen and edge sandwich structure. The central lumen serves as the primary drainage channel, collecting wound exudate or other fluids that need to be drained. The edge sandwich surrounds the central lumen, forming a protective layer and providing additional fluid channels.

[0127] Side-hole design: Multiple side holes are evenly distributed around the central lumen. These side holes penetrate the edge interlayer, directly communicating with the external environment, allowing fluid around the wound to enter the central lumen through the side holes and then be drained by negative pressure. The side-hole design optimizes drainage efficiency and ensures a wide range of fluid collection.

[0128] First-channel flushing holes: To enhance flushing effectiveness, first-channel flushing holes are cleverly designed into the edge interlayer structure. These flushing holes are located on the outside of the drainage tube interlayer, rather than directly inside the central lumen, preventing the flushing fluid from directly impacting the wound or affecting drainage efficiency. The flushing holes are connected to the external first-channel flushing pipe through the complex channel structure inside the edge interlayer.

[0129] Working principle and operation process

[0130] Installation and Connection: First, correctly place the negative pressure irrigation drainage tube into the surgical wound or treatment area, ensuring that the side holes fully cover the wound area. Then, connect one end of the drainage tube to the negative pressure suction device, and the other end to the first channel irrigation tube through a specific interface in the edge interlayer.

[0131] Flushing procedure: Activate the flushing system and inject an appropriate amount of flushing fluid (such as saline) into the marginal interstitial space through the first flushing channel. The flushing fluid flows within the marginal interstitial space and is evenly distributed around the drainage tube through the designed channel structure, effectively cleaning the wound surface without interfering with the drainage function of the central lumen.

[0132] Negative pressure suction: During or after irrigation, the negative pressure suction device is activated, and the negative pressure environment in the central lumen begins to work, drawing the mixture of wound exudate and irrigation fluid into the lumen through the side holes and eventually draining it out of the body. This process continues until the predetermined treatment goal is achieved.

[0133] Monitoring and maintenance: During treatment, medical staff need to regularly check the drainage effect and the use of irrigation solution, and adjust the irrigation rate and negative pressure intensity as needed to ensure the effectiveness of treatment and patient comfort.

[0134] Through the above design, the high-efficiency negative pressure irrigation and drainage system of this embodiment not only improves the efficiency and effectiveness of wound treatment, but also reduces direct interference with the wound through the fine lumen structure design, thus promoting the patient's rapid recovery.

[0135] Drainage tube body:

[0136] Materials: Utilizing a three-layer composite medical polymer material (outer layer is antibacterial silicone, middle layer is a pressure-resistant polyurethane support layer, and inner layer is a hydrophilic coating), with an outer diameter of 8mm. Internally, it consists of:

[0137] Central lumen: 5-7mm in diameter, main drainage channel.

[0138] Edge interlayer: annular cavity with a thickness of 1-3mm,

[0139] Side holes: Rhomboid side holes (2mm major axis, 1mm minor axis) are opened every 8mm on the outer wall of the central tube. The axis of the side holes forms a 45° angle with the tube body and penetrates the edge interlayer to reach the outside.

[0140] First channel flushing holes: Microholes with a diameter of 0.8 mm are opened at 15 mm intervals on the outer wall of the edge interlayer, arranged in a double spiral staggered pattern, avoiding the side hole area, to ensure that the flushing fluid covers no dead corners.

[0141] A specific implementation example of a high-efficiency negative pressure flushing and drainage system: The system automatically adjusts the flushing strategy based on the volume of flushing fluid and drainage fluid.

[0142] Step 1: System Initialization and Parameter Settings

[0143] Operation process:

[0144] Start the high-efficiency negative pressure flushing and drainage system and check that all components are in normal working order, including the flushing fluid speed control device, negative pressure device, drainage tube, high-precision sensor, etc.

[0145] Based on the patient's wound condition (such as wound size, depth, and amount of exudate) and the doctor's instructions, set the initial irrigation fluid rate and negative pressure value on the control device. For example, set the initial irrigation fluid rate to 50 ml / min and the initial negative pressure value to -120 mmHg.

[0146] Specific implementation:

[0147] Medical staff input patient information and wound details through the system interface.

[0148] The system recommends initial parameters based on its built-in algorithm, and medical staff can confirm or adjust the settings and then save them.

[0149] Step 2: Begin flushing with a small flow rate

[0150] Operation process:

[0151] The irrigation fluid speed control device is activated, and the wound is irrigated at the set initial low flow rate (e.g., 50 ml / min).

[0152] High-precision sensors monitor the rate of change in drainage fluid volume in real time and compare it with the rate of flushing fluid.

[0153] Specific implementation:

[0154] The flushing fluid is injected into the wound through the central lumen of the negative pressure flushing drainage tube.

[0155] The drainage fluid is discharged through the side holes and the central lumen by the negative pressure suction device.

[0156] The sensor transmits data to the control device, which displays the real-time flushing fluid rate and drainage fluid rate.

[0157] Step 3: Determine and adjust the flushing fluid rate

[0158] Operation process:

[0159] When the monitored drainage volume is comparable to the current irrigation volume (e.g., the drainage rate reaches 50 ml / min), the system automatically or according to the doctor's instructions will gradually increase the irrigation rate (e.g., by 10 ml / min each time).

[0160] During the adjustment process, the volume of drainage fluid and flushing fluid are continuously monitored to ensure that the two are kept in dynamic balance.

[0161] Specific implementation:

[0162] The system automatically determines whether the flushing fluid speed needs to be adjusted based on a preset algorithm.

[0163] Medical staff can also manually adjust the flushing fluid rate based on real-time data.

[0164] The system records the time and speed changes for each adjustment.

[0165] Step 4: Prevent rinsing fluid from overflowing.

[0166] Operation process:

[0167] If the flushing fluid volume is found to be greater than the drainage fluid volume (e.g., the flushing fluid rate reaches 80 ml / min, while the drainage fluid rate is only 60 ml / min), immediately stop increasing the flushing fluid rate and appropriately reduce the flow rate (e.g., reduce to 70 ml / min) to prevent flushing fluid overflow.

[0168] Specific implementation:

[0169] The system is set with a threshold value. When the difference between the rinsing fluid velocity and the drainage fluid velocity exceeds a certain range, a deceleration mechanism is automatically triggered.

[0170] After receiving the alarm, medical staff checked the wound and manually adjusted the irrigation fluid rate.

[0171] Step 5: Security and Protection Mechanisms

[0172] Operation process:

[0173] The system is equipped with an overflow warning device. When an overflow trend of the flushing fluid is detected (such as when the flushing fluid speed is continuously higher than the drainage fluid speed), an alarm is immediately issued and the flushing fluid speed is automatically reduced.

[0174] In the event of a system malfunction or severe overflow of flushing fluid, the emergency shutdown device should be activated immediately to protect patient safety.

[0175] Specific implementation:

[0176] The overflow warning device alerts medical staff through sound and light signals.

[0177] The emergency shutdown device achieves rapid shutdown by cutting off the power supply or closing the valve.

[0178] The system records the time and cause of the failure for subsequent analysis.

[0179] Step 6: Recording and Feedback

[0180] Operation process:

[0181] Throughout the rinsing process, key parameters such as rinsing fluid volume, drainage fluid volume, rinsing speed, and rinsing time were recorded.

[0182] The flushing effect is evaluated based on the recorded data, and the flushing fluid speed control device is adjusted and optimized based on the evaluation results.

[0183] Specific implementation:

[0184] The system automatically generates a flushing process report, including key parameter change curves and evaluation results.

[0185] Medical staff adjusted the subsequent treatment plan based on the report.

[0186] The system synchronizes the data to the hospital information system (HIS) for long-term tracking and analysis.

[0187] Practical application cases

[0188] Patient's condition:

[0189] The patient, Mr. Li, male, 45 years old, suffered an open fracture of his right lower leg due to a car accident, and there was a lot of exudate from the wound after surgery.

[0190] Treatment process:

[0191] Medical staff activated the high-efficiency negative pressure flushing and drainage system, setting the initial flushing fluid rate to 50 ml / min and the initial negative pressure value to -120 mmHg.

[0192] The system begins flushing at a low flow rate and monitors the drainage volume in real time.

[0193] After 30 minutes, the drainage volume was monitored to reach 50 ml / min, and the system automatically adjusted the flushing fluid rate to 60 ml / min.

[0194] One hour later, it was found that the flushing fluid rate reached 70 ml / min, while the drainage fluid rate was only 65 ml / min. The system immediately issued an alarm and automatically reduced the flushing fluid rate to 65 ml / min.

[0195] After the treatment, the system generated a flushing process report, showing that the total amount of flushing fluid was 3000ml and the total amount of drainage fluid was 2950ml, indicating that the flushing effect was good.

[0196] Based on the report, medical staff adjusted the subsequent treatment plan and continued to use the system for wound management.

[0197] Through the above specific implementation examples, it can be seen that the high-efficiency negative pressure irrigation and drainage system can automatically adjust the irrigation strategy according to the amount of irrigation fluid and drainage fluid, thereby improving the effectiveness and safety of treatment.

[0198] Specific implementation examples in the patent specification: A high-efficiency negative pressure flushing and drainage system with an automatic adjustment strategy based on the properties of the drainage fluid.

[0199] The high-efficiency negative pressure flushing and drainage system proposed in this invention is characterized by comprising a negative pressure flushing and drainage tube and a matching negative pressure system, which can automatically adjust the flushing strategy according to the properties of the drainage fluid. The specific method is as follows:

[0200] Step 1: Detect the properties of the drainage fluid

[0201] Technical means: The system integrates a variety of advanced technologies, such as optical analysis, electrochemical sensing, and biomolecular recognition, to monitor key indicators such as protein concentration, cell type, and pH value in the drainage fluid in real time.

[0202] Implementation method: Connect the drainage fluid property detection system to the negative pressure flushing drainage tube. When the drainage fluid flows out through the drainage tube, it is analyzed in real time by the detection system.

[0203] Data recording: The detection system uses high-precision sensors to record various properties of the drainage fluid and transmits the data to the control system for processing.

[0204] Step 2: Flush Strategy Formulation and Optimization

[0205] Personalized approach: Based on the drainage fluid properties data provided by the monitoring system, combined with the patient's wound condition and treatment needs, doctors develop personalized irrigation strategies, including parameters such as the type and concentration of irrigation fluid and the frequency of irrigation.

[0206] Intelligent optimization: During treatment, the system continuously collects and analyzes relevant data on drainage and irrigation fluids, and automatically adjusts the irrigation strategy using built-in algorithms. For example, when an increase in bacterial concentration is detected in the drainage fluid, the system automatically increases the irrigation frequency or replaces it with an antibiotic solution.

[0207] Implementation method: The control system adjusts the flushing parameters through the flushing fluid speed control device and the negative pressure control device based on the initial strategy set by the doctor and the real-time data analysis results.

[0208] Step 3: Monitoring and Adjusting the Rinsing Process

[0209] Real-time monitoring: The system uses high-precision sensors to monitor key parameters such as the properties of the drainage fluid, the flushing fluid rate, and the negative pressure environment in real time.

[0210] Abnormal alarm: When an abnormal situation is detected, such as abnormal flushing fluid speed or unstable negative pressure environment, the system will immediately issue an alarm and automatically adjust the flushing strategy through the control system, such as reducing the flushing speed or adjusting the negative pressure value.

[0211] Manual adjustment: Doctors can view various data during the flushing process in real time through the system interface and make manual adjustments as needed to ensure the flexibility and controllability of the treatment.

[0212] Step 4: Data Analysis and Feedback

[0213] Comprehensive Analysis: After treatment is completed, the system performs a comprehensive analysis and summary of the data from the entire treatment process, including the changing trends of the drainage fluid properties, records of adjustments to the irrigation strategy, and evaluation of the treatment effect.

[0214] Feedback and Optimization: Based on data analysis results, the system provides doctors with optimization suggestions to help them better understand the progress and problems of wound treatment. Simultaneously, the system feeds data back to the management departments of research institutions or medical facilities to improve the irrigation fluid property detection system and the methods for developing irrigation strategies.

[0215] Implementation: The data analysis module performs in-depth analysis of the recorded data to generate detailed treatment reports and optimization suggestions for doctors and researchers to refer to.

[0216] System Composition

[0217] Negative pressure irrigation and drainage tube: Designed as a tube that can be inserted into the wound and negative pressure sponge, it has dual functions of irrigation and drainage. The tube's interior adopts a central lumen and edge sandwich structure, and the side holes and irrigation holes are designed to optimize drainage and irrigation efficiency.

[0218] The supporting negative pressure system includes a drainage volume recorder, an irrigation volume recorder, an irrigation fluid rate control device, a negative pressure control device, and a drainage fluid property detection system. Each component employs high-precision sensors and a stable performance design to ensure the accuracy and safety of the treatment.

[0219] Operating procedures

[0220] System Preparation: Check that the negative pressure irrigation drainage tube and its supporting negative pressure system are intact and undamaged, ensuring that the pipe connections are tight and leak-free. Wound Treatment: Thoroughly clean the wound, removing necrotic tissue and foreign objects. Insert the negative pressure irrigation drainage tube and / or negative pressure sponge into the wound, ensuring that the tube fits tightly against the wound.

[0221] Parameter settings: Based on the size and depth of the wound and the results of the drainage fluid properties test, set appropriate irrigation fluid speed, negative pressure level and personalized irrigation strategy.

[0222] Initiating treatment: Turn on the irrigation fluid rate control device and negative pressure control device to begin irrigation and drainage treatment. The system monitors and records relevant data in real time.

[0223] Process monitoring: Medical staff regularly check the drainage effect and irrigation fluid usage, adjusting the irrigation rate and negative pressure intensity as needed. The system automatically detects abnormalities and issues alarms.

[0224] End of treatment: After treatment, turn off the irrigation fluid speed control device and the negative pressure control device. Remove the negative pressure irrigation drainage tube, disinfect and bandage the wound. Clean up the system equipment and record the treatment data.

[0225] A specific implementation example of a high-efficiency negative pressure flushing and drainage system—the function of automatically adjusting the flushing strategy according to the user-defined negative pressure sponge specifications.

[0226] The high-efficiency negative pressure flushing and drainage system of the present invention is characterized by comprising a negative pressure flushing and drainage pipe and a matching negative pressure system, which can automatically adjust the flushing strategy according to the user-defined negative pressure sponge specifications. The specific steps are as follows:

[0227] User enters negative pressure sponge specifications.

[0228] Users can enter detailed specifications of the negative pressure sponge through the system interface, including but not limited to dimensions (such as length, width, and thickness) and material type (such as polyurethane, polyvinyl alcohol, etc.). For example, users can select a polyurethane negative pressure sponge with a length of 10cm, a width of 5cm, and a thickness of 2cm.

[0229] The system receives and parses the specification information.

[0230] The system receives the negative pressure sponge specifications input by the user and parses them using a built-in algorithm or database. Based on parameters such as the sponge's absorbency and permeability, the system initially determines the initial volume and speed for each rinse. For example, for the polyurethane sponge of the above specifications, the system might initially set the initial rinsing speed to 50 ml / min and the initial rinsing volume to 100 ml.

[0231] Automatically set flushing strategy

[0232] Based on the judgment result in step 2, the system automatically adjusts the intelligent flushing fluid speed control device, preset the initial flushing speed and flushing volume. This step ensures that the flushing process meets the drainage requirements while avoiding discomfort or waste of resources caused by over-flushing. For example, the system sets the flushing fluid speed control device to 50ml / min and presets the total flushing volume to 100ml.

[0233] Real-time monitoring and dynamic adjustment

[0234] During the flushing process, the system continuously monitors the rate and volume of the drainage fluid using a high-precision monitoring module. Based on real-time data, the system dynamically adjusts the flushing fluid rate using intelligent algorithms. For example, if the drainage fluid rate is detected to be too fast, the system may appropriately increase the flushing fluid rate to ensure thorough flushing; conversely, if the drainage fluid rate is too slow, the system may reduce the flushing fluid rate to avoid wasting resources.

[0235] In practice, the system records the drainage fluid rate and volume every minute and dynamically adjusts the irrigation fluid rate according to a preset algorithm. For example, if the drainage fluid rate is 30 ml / min in the initial stage, the system maintains an irrigation rate of 50 ml / min; as the treatment progresses, if the drainage fluid rate increases to 40 ml / min, the system may adjust the irrigation rate to 60 ml / min.

[0236] Feedback and Optimization

[0237] The system records key parameters and effects during each irrigation process, including irrigation fluid velocity, drainage fluid velocity, and irrigation volume. Through data analysis, the system continuously optimizes irrigation strategies, providing more precise and personalized recommendations for future treatments.

[0238] For example, the system can generate a report after each treatment, detailing the parameters and effects of the irrigation process. Based on data analysis from multiple reports, the system can identify the optimal irrigation strategy for a specific size of sponge for a particular wound type and automatically apply this strategy in future treatments.

[0239] Here is a specific example:

[0240] System preparation: Check that the negative pressure flushing drainage tube and the matching negative pressure system are intact and undamaged, and ensure that all components are tightly connected and leak-free.

[0241] User input: Users can input the specifications of a polyurethane negative pressure sponge with a length of 10cm, a width of 5cm, and a thickness of 2cm through the system interface.

[0242] System Analysis and Settings: The system receives and analyzes the specification information, initially setting the initial flushing speed to 50 ml / min and the initial flushing volume to 100 ml. The system automatically adjusts the intelligent flushing fluid speed control device to match these parameters.

[0243] Treatment begins: Insert the negative pressure irrigation and drainage tube into the patient's wound and initiate irrigation and negative pressure suction. The system begins real-time monitoring of the drainage rate and volume, dynamically adjusting the irrigation rate as needed.

[0244] Real-time monitoring and adjustment: During treatment, the system records the drainage rate and volume every minute. If the drainage rate increases to 40 ml / min, the system adjusts the flushing rate to 60 ml / min to ensure thorough flushing.

[0245] Treatment Completion and Feedback: After treatment, the system generates a detailed report recording various parameters and effects during the irrigation process. Based on data analysis from multiple reports, the system optimizes the irrigation strategy for future treatment reference.

[0246] Through the above specific embodiments, the high-efficiency negative pressure irrigation and drainage system of the present invention can automatically adjust the irrigation strategy according to the user-defined negative pressure sponge specifications, thereby improving the treatment effect and safety, and providing patients with a more personalized and efficient wound treatment solution.

Simultaneously, through data synchronization with the HIS system, it enhances the informatization level of medical services, providing medical staff with more comprehensive and accurate patient information and treatment data support.

[0274] Example of the implementation of an integrated high-efficiency negative pressure flushing and drainage system and its supporting negative pressure control system

[0275] The high-efficiency negative pressure irrigation and drainage system of the present invention mainly includes a negative pressure irrigation and drainage tube and its supporting negative pressure system. The negative pressure system further includes a drainage fluid volume recorder, an irrigation fluid volume recorder, an irrigation fluid speed control device, a negative pressure control device, and a drug injection unit. The drug injection unit is used to automatically inject drugs after irrigation is completed to optimize the treatment effect.

[0276] System Composition

[0277] Negative pressure flushing drainage tube:

[0278] Designed as a tube that can be inserted into the wound and negative pressure sponge, it has both flushing and drainage functions.

[0279] The pipeline has a central cavity and an edge sandwich structure. The central cavity is responsible for drainage, and the edge sandwich is equipped with flushing holes.

[0280] The material should have good biocompatibility and corrosion resistance.

[0281] Supporting negative pressure system:

[0282] Drainage fluid volume recorder: Employs a high-precision sensor to monitor and record drainage fluid data in real time.

[0283] Fluid volume recorder: It also uses a high-precision sensor to monitor and record the flushing fluid data in real time.

[0287] Specific implementation steps

[0288] The system is set to automatically inject medication at specific intervals and times:

[0289] Users can set the cycle (e.g., daily, every other day) and specific time (e.g., morning, afternoon) for automatic drug injection through the system interface.

[0290] The system saves the drug injection plan according to the user's settings.

[0291] Medicine preparation and storage:

[0292] The system is equipped with a drug storage unit, and users need to place the specified drugs (such as antibiotic solutions, growth factors, etc.) in the storage unit in advance.

[0293] Ensure the medication is within its expiration date and of the correct type. The system automatically identifies the medication type and verifies whether it meets the injection plan requirements. Flushing process:

[0294] Place the negative pressure irrigation drainage tube correctly into the surgical wound or treatment area.

[0295] Start the flushing system and inject an appropriate amount of flushing fluid (such as saline) into the marginal interstitial space through the first flushing channel. The flushing fluid flows within the marginal interstitial space, evenly cleaning the wound surface without interfering with the drainage function of the central lumen.

[0296] When the negative pressure suction device is turned on, the negative pressure environment in the central lumen draws the mixture of wound exudate and irrigation fluid into the lumen through the side holes, and finally drains it out of the body.

[0297] The medication is automatically injected after rinsing.

[0298] After a flushing cycle is completed, the system automatically injects the designated medication into the negative pressure sponge or wound area through the flushing pipe according to the preset injection plan.

[0299] The system precisely controls the injection speed and volume to ensure that the drug is evenly distributed and achieves the best effect.

[0300] Real-time monitoring and feedback:

[0301] During the drug injection process, the system continuously monitors the injection status, including whether there are any abnormalities in the injection speed, volume, and pressure (such as pipeline blockage, drug leakage, etc.).

[0302] If any abnormality occurs, the system will immediately issue an alarm and stop the injection process to ensure patient safety and treatment effectiveness.

[0303] Recording and Analysis:

[0304] The system automatically records detailed parameters and effects of each drug injection, including injection time, drug type, and injection volume.

[0305] By analyzing data, we can assess the impact of drug injection on the effectiveness of negative pressure therapy and provide optimization suggestions for future treatments.

[0306] Specific implementation examples

[0307] Implementation scenario: A patient suffers from wound infection due to surgery and requires continuous negative pressure suction therapy and regular medication infusion.

[0308] Operating steps:

[0309] System settings:

[0310] Medical staff can set the time for automatic injection of antibiotic solution at 10:00 AM every day through the system interface.

[0313] Flushing and drainage:

[0314] Insert the negative pressure irrigation drainage tube into the patient's wound and start the irrigation system to clean the wound.

[0315] At the same time, the negative pressure suction device is turned on to drain the wound exudate.

[0316] Automated drug dispensing:

[0317] The next morning at 10 a.m., the system automatically stopped rinsing and injected antibiotic solution into the negative pressure sponge or wound area through the rinsing pipe.

[0318] The system precisely controls the injection speed and volume to ensure uniform drug distribution.

[0319] Real-time monitoring:

[0320] During the drug injection process, the system continuously monitored the injection status and no abnormalities were detected.

[0321] Recording and Analysis:

[0322] The system automatically records the detailed parameters and effects of this drug injection.

[0324] Through the above specific implementation examples, the function of the high-efficiency negative pressure irrigation and drainage system and its matching negative pressure control system of the present invention to automatically inject medicine after irrigation has been effectively verified, providing a more convenient, safe and effective solution for wound treatment.

[0325] Specific implementation examples in the patent specification: A high-efficiency negative pressure flushing and drainage system that automatically adjusts the flushing strategy based on the velocity of the flushing fluid and the drainage fluid.

[0326] A high-efficiency negative pressure flushing and drainage system is characterized by comprising a negative pressure flushing and drainage pipe and a matching negative pressure system, wherein the negative pressure system can automatically adjust the flushing strategy according to the velocity of the flushing fluid and the velocity of the drainage fluid. Specifically, it includes the following steps: System Composition

[0330] Data Analysis and Comparison (Step 2)

[0331] The data processing module analyzes and compares the real-time monitored flushing fluid velocity and drainage fluid velocity to evaluate the effectiveness of the current flushing strategy. By comparing the differences between the two, the system determines whether the flushing strategy needs to be adjusted.

[0332] Automatic adjustment of flushing strategy (Step 3)

[0333] Based on data analysis and comparison results, the system automatically adjusts the flushing strategy. If the flushing fluid velocity is too fast or the drainage fluid velocity is too slow, the system reduces the flushing fluid velocity; if the flushing fluid velocity is too slow or the drainage fluid velocity is too fast, the system increases the flushing fluid velocity. This adjustment process ensures that the flushing process is both effective and safe.

[0334] Monitoring the effects of strategy adjustments (Step 4)

[0335] After adjusting the flushing strategy, the system continues to monitor the flushing fluid velocity and drainage fluid velocity in real time to evaluate the effectiveness of the adjusted strategy. If the adjusted strategy still fails to achieve the expected results, the system repeats the data analysis and comparison steps until the optimal flushing strategy is found.

[0336] Recording and Feedback (Step 5)

[0337] The system records key parameters and strategy adjustments during each irrigation process, including irrigation fluid velocity, drainage fluid velocity, and irrigation strategy adjustment time. This data is used for subsequent analysis and optimization, providing precise and personalized recommendations for future treatment.

[0338] Security and Protection Mechanisms (Step 6)

[0339] The system is equipped with safety and protection mechanisms.
