Traditional treatment methods include: 1. Open dressing: Daily or every other day, exposing the wound to air, increasing the risk of secondary infection, prolonging healing time, and causing significant patient discomfort; 2. Simple negative pressure drainage: While effective in draining exudate, the equipment is complex, costly, and provides poor coverage for superficial wounds; 3. Secondary suturing: Often difficult to perform on patients with poor nutritional status, and the high tension increases the risk of re-dehiscence; 4. Using a stoma bag connected to a negative pressure drainage device: Maintaining negative pressure at a set value for drainage, but when the patient's condition changes, the previously set negative pressure may become too high, worsening the patient's condition.

Detailed Implementation
[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or parts / elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0021] The following describes an intelligent wound exudate drainage and sealing device according to an embodiment of the present invention, with reference to the accompanying drawings.
[0022] Figure 1 This is a schematic diagram of the structure of an intelligent wound exudate drainage and sealing device provided in one embodiment of this application; Figure 2 This is a schematic diagram illustrating the usage of an intelligent wound exudate drainage and sealing device according to an embodiment of this application; as shown. Figure 1-2As shown: This intelligent wound exudate drainage and sealing device includes a flexible base 1, a sealed container 2 connected to the flexible base 1, a drainage tube 3 sleeved on the sealed container 2, a pressure regulating module 4 and a drainage bag 5 connected to the end of the drainage tube 3, an optical monitoring module 6, and a control module 7 communicatively connected to both the pressure regulating module 4 and the optical monitoring module 6; wherein, the optical monitoring module 6 includes a color sensor 61, which focuses on the sealed container 2 or the drainage tube 3; the pressure regulating module 4 includes a pressure sensor 41 and a micro-controlled solenoid valve 42.
[0023] Specifically, the flexible chassis 1 is used to connect the sealed container 2 to the patient's wound; the sealed container 2 can be a stoma bag, used to provide a sealed environment for the drainage tube, preventing the patient's wound from being exposed to air and reducing the risk of infection; the drainage tube 3 is used to provide a removal channel for clearing wound exudate and necrotic tissue; the pressure regulating module 4 is used to provide a continuous negative pressure environment for the drainage tube 3, thereby achieving negative pressure drainage; the pressure sensor 41 is used to detect the pressure value in the drainage tube 3 in real time, thereby accurately regulating the pressure; the micro-controlled solenoid valve 42 is used to open or close or adjust the opening degree according to the received control command information, so as to maintain the negative pressure within the set ideal range and prevent excessive negative pressure. Tissue damage or insufficient negative pressure can lead to drainage failure; the drainage bag 5 is used to store wound exudate and necrotic tissue; the optical monitoring module 6 and its color sensor 61 are used to monitor the liquid seeping from the drainage tube 3 or the sealed container 2, and transmit the detected information signal to the control module 7; the control module 7 is used to analyze the RGB values obtained from the color sensor 61, thereby identifying the color and transparency of the drainage fluid, and obtaining a judgment result, determining whether the drainage fluid is red or yellow-green, cloudy or clear, and its properties; when the judgment result is red or yellow-green or cloudy, the control module 7 controls the pressure regulating module 4 to lower the pressure to reduce possible bleeding.
[0024] It should be noted that, Figure 1 This is a schematic diagram of the conventional state of the intelligent wound exudate drainage closed device of this application. Before use, the flexible base 1 and the closed container 2 are sealed, and the front end of the drainage tube 3 is inside the closed container 2. During use, an opening needs to be cut in the center of the flexible base 1, and then the drainage tube 3 is passed through the opening of the flexible base 1 and inserted into the designated position.
[0025] It should also be noted that the sealed container 2 and the drainage tube 3 are connected in a detachable and sealed manner. More specifically, a threaded interface or a snap-fit interface can be provided at the interface between the sealed container 2 and the drainage tube 3, and a silicone sealing ring is provided at the interface to achieve a seal.
[0026] It should also be noted that the drainage bag 5 and the flexible chassis 1 are replaced at a low frequency. Therefore, the optical monitoring module 6 of this application does not need to monitor the drainage bag 5 and the flexible chassis 1. It only needs to manually set the replacement time according to actual needs.
[0027] It should also be noted that the intelligent wound exudate drainage and sealing device of this application is an early warning and emergency device that monitors wounds using sensors and determines color based on the monitoring results. If a risk color is obtained, the device adjusts the instrument pressure to prevent the risk from escalating, or notifies relevant personnel for assessment and diagnosis. The device in this application is essentially an intelligent monitoring and adjustment device based on photoelectric principles and does not belong to the category of disease treatment and diagnosis methods.
[0028] The intelligent wound exudate drainage closed device according to this application can be used for a long time after a single installation. The drainage device provides a closed environment, which prevents the invasion of bacteria and accelerates wound healing. Patients experience less pain and can get out of bed. It can monitor and automatically detect the status of the drainage fluid and adjust the negative pressure value in a timely manner according to the status to avoid harming the patient.
[0029] According to one embodiment of this application, the front side of the drainage tube 3 is provided with a plurality of drainage holes.
[0030] Specifically, the drainage hole is placed inside the patient's wound, through which tissue fluid can seep into the drainage tube 3.
[0031] According to one embodiment of this application, the outer end face of the flexible chassis 1 is provided with medical pressure-sensitive adhesive 11, and the outer end face of the medical pressure-sensitive adhesive 11 is provided with release paper 12.
[0032] Specifically, the outer end face of the flexible base 1 can be coated with medical pressure-sensitive adhesive 11, and the medical pressure-sensitive adhesive 11 is covered with release paper 12. When in use, the release paper 12 can be peeled off and the material can be pasted onto the skin around the wound.
[0033] According to one embodiment of this application, the drainage holes are distributed within a range of 2 to 5 cm from the front end of the drainage tube 3; the diameter of the drainage holes is 1 to 2 mm; and the spacing between the plurality of drainage holes is 5 to 8 mm.
[0034] Specifically, the drainage holes are distributed within a range of 2-5cm at the front end of the drainage tube 3, which can lock the negative pressure suction range to the lesion area and avoid "full tube adsorption" which reduces the effect of negative pressure drainage; the purpose of the hole diameter of 1-2mm is to drain only liquid and fine particles, physically blocking large tissues and avoiding blockage of the drainage tube; the spacing between the drainage holes is 5-8mm to avoid the spacing being too small, which would result in low strength and easy breakage when bending, and at the same time to avoid the spacing being too large, which would result in poor drainage backup channel effect.
[0035] According to one embodiment of this application, an alarm module 8 is also included, which is communicatively connected to the control module 7.
[0036] Specifically, when the judgment result is red, yellow-green, or cloudy, the alarm module 8 notifies relevant personnel to understand the patient's condition and take timely action. The alarm module 8 can be a buzzer, an indicator light, a computer program, or a mobile application, etc.
[0037] Based on the above embodiments, this invention also proposes a method for using an intelligent wound exudate drainage sealing device, comprising the following steps: Step S010: Cut an opening in the center of the flexible base plate 1 according to actual needs; Step S020: Pass the drainage tube 3 through the opening of the flexible base plate 1 and insert it into a first designated position, and seal the connection between the drainage tube 3 and the sealed container 2; Step S030: Attach the flexible base plate 1 to a second designated position to ensure a tight fit; Step S040: Connect the end of the drainage tube 3 to the pressure regulating module 4 and the drainage bag 5, and adjust the pressure of the pressure regulating module 4 to -75mmHg to -125mmHg; Step S050: The optical monitoring module 6 monitors the sealed container 2 or the drainage tube 3: color sensor 61 The first RGB value is obtained near the designated location where the flexible chassis 1 is attached; the color sensor 61 continuously detects the sealed container 2 or the drainage tube 3 to obtain multiple second RGB values; the first RGB value and the multiple second RGB values are transmitted to the control module 7; step S060: the control module 7 analyzes the second RGB values using the first RGB value as a reference value to identify the color and transparency of the drainage fluid and obtain a judgment result, determining whether the drainage fluid is red or yellow-green, turbid or clear, and its properties; step S070: when the judgment result is red, yellow-green, or turbid, the control module 7 controls the pressure regulating module 4 to reduce the pressure to -25 mmHg to -50 mmHg.
[0038] Specifically, the pressure of pressure regulating module 4 is adjusted to -75 mmHg to -125 mmHg. The negative pressure must be maintained within the set ideal range to prevent tissue damage due to excessive negative pressure or drainage failure due to insufficient negative pressure. If the drainage fluid is red, yellow-green, or turbid based on the test results, it indicates abnormalities such as bleeding, inflammation, tissue necrosis, or sloughing. In this case, the negative pressure provided by the pressure regulating module should be reduced to avoid injury to the patient due to equipment malfunction. The pressure can be lowered to -25 mmHg to -50 mmHg in this situation.
[0039] It should be noted that the color of the drainage fluid is identified by analyzing the second RGB values. If the analysis result is red or yellowish-green, it indicates that the drainage fluid is red or there is inflammation, requiring treatment. Simultaneously, by using the first RGB values as a reference, analyzing the second RGB values reveals that for patients with yellow or white skin, lower R, G, and B values indicate dimmer reflected light, suggesting that the reflected light in the drainage tube is being absorbed by something, indicating that the drainage fluid is cloudy and requires treatment.
[0040] According to one embodiment of this application, when the drainage tube 3 is inserted into the first designated position in step S020, the drainage hole on the front side of the drainage tube 3 is placed in the first designated position.
[0041] According to one embodiment of this application, in step S030, by tearing off the release paper 12, the medical pressure-sensitive adhesive 11 is pasted at the second designated position, thereby making the flexible chassis 1 fit tightly.
[0042] According to one embodiment of this application, before inserting the drainage tube 3 into the first designated position in step S020, the front end of the drainage tube 3 is cut according to actual needs, thereby adjusting the position of the drainage hole at the front end of the drainage tube 3 so that the drainage hole can be placed in the first designated position.
[0043] According to one embodiment of this application, in step S070, when the judgment result is red, yellow-green, or turbid, the control module 7 controls the alarm module 8 to send an alarm to relevant personnel.
[0044] It should be noted that if a patient's condition is not suitable for determining whether the turbidity is present, this alarm condition can be turned off.
[0045] According to the present invention, an intelligent wound exudate drainage closed device is manufactured using a method that allows for long-term use after a single installation. The drainage device provides a closed environment, preventing bacterial invasion and accelerating wound healing. Patients experience less pain and can get out of bed. It can monitor and automatically detect the state of the drainage fluid and adjust the negative pressure value accordingly to prevent injury to the patient. When a risky condition is detected, an alarm module can notify relevant personnel for timely handling to avoid delays.
[0046] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present invention are within the protection scope of the present invention.
