Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a leak-proof device for abdominal drainage tubes. Background Technology

[0002] After laparoscopic surgery, a drainage tube is usually placed. The drainage tube can drain accumulated fluid and blood in a timely manner, and the characteristics of the drainage fluid can be observed. This can prevent postoperative infection, promote the resolution of inflammation, ensure good healing of the surgical wound, reduce the occurrence of complications, and facilitate the patient's rapid recovery.

[0003] Currently, when using conventional drainage tubes, the small diameter of the tube creates a suture gap between it and the abdominal wall puncture site. Postoperatively, ascites is prone to leaking out through this gap, resulting in damp dressings that reduce patient comfort and increase the workload of medical staff due to frequent dressing changes. This also increases the risk of infection and tube dislodgement. Furthermore, the alkaline nature of the wound exudate causes continuous skin irritation, exacerbating patient pain, delaying healing, and increasing medical costs. Summary of the Invention

[0004] To address the aforementioned problems, this utility model aims to provide an anti-leakage device for abdominal drainage tubes, which can prevent the drainage tube from coming off, reduce leakage of exudate, and facilitate operation.

[0005] The main idea of ​​the technical solution adopted in this utility model is as follows: by designing a fixed airbag and an expanding airbag, the drainage tube can be limited on both sides of the abdominal wall to prevent it from dislodging; at the same time, the fixed airbag at the inner abdominal wall can block the puncture site and reduce the leakage of exudate; a negative pressure plate is also set between the outer abdominal wall and the expanding airbag. When the expanding airbag is inflated, it squeezes the sealing plate to put it into a negative pressure state, which can draw the exudate into the negative pressure plate and prevent it from leaking outward; the inflation tube includes two connected inflation chambers, inflation chamber one and inflation chamber two, which can be used to judge the fullness of the fixed airbag by observing the expanding airbag, so as to facilitate timely gas replenishment. Moreover, the fixed airbag is filled first and the expanding airbag is filled later, which makes it easy to adjust the fullness of the expanding airbag, and thus adjust the pressure of the negative pressure plate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An anti-leakage device for an abdominal drainage tube includes a drainage tube with an annular groove and a negative pressure plate on the annular groove. The negative pressure plate is slidably connected to the drainage tube, and an enlarging airbag capable of compressing the negative pressure plate is also provided on the annular groove.

[0008] Furthermore, the above technical solution includes a fixing airbag on the drainage tube. The fixing airbag is located on one side of the annular groove and on both sides of the negative pressure plate, respectively, along with the expanding airbag.

[0009] Furthermore, the negative pressure plate is provided with several leakage absorption holes along the circumferential direction.

[0010] Furthermore, the above technical solution includes a liquid collection head at one end of the drainage tube near the fixed airbag, and the liquid collection head has multiple liquid inlet holes.

[0011] Furthermore, according to the above technical solution, an air inflator is provided on the wall of the drainage tube.

[0012] Furthermore, the above technical solution provides that the inflation tube has an inflation chamber 1 and an inflation chamber 2. The inflation chamber 1 is used to connect the outside world with the fixed airbag, and the inflation chamber 2 is used to connect the fixed airbag with the expanded airbag.

[0013] The beneficial effects of this utility model are:

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] The inventors discovered that when using conventional drainage tubes, the small diameter of the tube creates a suture gap between it and the abdominal wall puncture site. This gap makes it easy for ascites to leak out postoperatively, leading to damp dressings that reduce patient comfort and require frequent dressing changes, increasing the workload for medical staff. Furthermore, this increases the risk of infection and tube dislodgement, and the alkaline nature of the wound exudate causes continuous skin irritation, exacerbating patient pain, delaying healing, and increasing medical costs.

[0028] Based on the above findings, this application proposes an anti-leakage device for abdominal drainage tubes. By designing a fixed airbag 3 and an expanding airbag 6, the device limits the drainage tube 1 on both sides of the abdominal wall, preventing it from dislodging. At the same time, the fixed airbag 3 at the inner abdominal wall can block the puncture site, reducing exudate leakage. A negative pressure plate 5 is also provided between the outer abdominal wall and the expanding airbag 6. When the expanding airbag 6 is inflated, it squeezes the sealing plate to put it in a negative pressure state, which can draw the exudate into the negative pressure plate 5 and prevent it from leaking outward. The inflation tube 9 includes two connected inflation chambers 1 and 2, which can be used to judge the fullness of the fixed airbag 3 by observing the expanding airbag 6, so as to replenish the gas in time. Furthermore, the fixed airbag 3 is inflated first and the expanding airbag 6 is inflated later, which makes it easy to adjust the fullness of the expanding airbag 6, thereby adjusting the pressure on the negative pressure plate 5.

[0029] Example 1

[0030] See Figure 1 - Figure 8This application discloses an anti-leakage device for an abdominal drainage tube, comprising a drainage tube 1, with a collection head 2 at one end of the drainage tube 1. The collection head 2 has multiple inlet holes 201, through which exudate enters the collection head 2 and is then discharged through the drainage tube 1, preventing blockage of the drainage tube 1, reducing the frequency of tube replacement, and lowering the workload of medical staff. The drainage tube 1 is available in various diameters, ranging from 14-32 mm, allowing medical staff to select the appropriate drainage tube 1 according to their actual needs. The drainage tube 1 is made of medical-grade silicone rubber, which has good biocompatibility, effectively reducing tissue irritation and allergic reactions, and possesses high tear resistance and high tensile strength, making it less prone to breakage during removal. The drainage tube 1 is available in various lengths, including 250 mm, 300 mm, 350 mm, 400 mm, 450 mm, and 500 mm, allowing medical staff to choose according to their specific needs.

[0031] A fixing airbag 3 is also fitted on the drainage tube 1. After inflation, the diameter of the fixing airbag 3 is larger than that of the drainage tube 1. It is placed on the inner abdominal wall to prevent the drainage tube 1 from slipping outward.

[0032] An annular groove 4 is also provided on the drainage tube 1, and the annular groove 4 is located on the side of the fixed airbag 3 away from the liquid collection head 2. A negative pressure plate 5 is slidably connected to the annular groove 4, and the negative pressure plate 5 is sleeved on the annular groove 4 and has a funnel-shaped structure. Multiple seepage absorption holes 501 are provided along the circumference of the end of the negative pressure plate 5 near the liquid collection head 2.

[0033] An expanding airbag 6 is also provided on the annular groove 4 of the negative pressure plate 5. The thickness of the outer circumference of the expanding airbag 6 is greater than the thickness of the two end faces. Therefore, when it is inflated, the two ends expand first and squeeze the negative pressure plate 5.

[0034] In the initial state, the expanding airbag 6 is fixedly connected to the side wall of the annular groove 4 away from the collection head 2. When the expanding airbag 6 is inflated, both the axial length and radial length of the expanding airbag 6 increase, thereby squeezing the negative pressure plate 5 and causing it to slide closer to the collection head 2. When inflation continues, the negative pressure plate 5 squeezes the outer abdominal wall, and other contents inside the negative pressure plate 5 are discharged, creating a negative pressure state. When exudate seeps out through the drainage puncture port, it flows through the exudate absorption hole 501 of the negative pressure plate 5 and enters the negative pressure plate 5 for storage under the action of negative pressure, preventing exudate from seeping out and reducing infection.

[0035] Example 2

[0036] In order to facilitate the adjustment of the negative pressure level of the negative pressure plate 5 and to facilitate the observation of the status of the fixed airbag 3 and to determine whether gas needs to be replenished, an inflation tube 9 is provided on the wall of the drainage tube 1.

[0037] The drainage tube 1 is equipped with a connecting tube 101 for communication with an inflation device such as a syringe, and an air valve is installed on the connecting tube 101. The inflation tube 9 is integrally connected to the inner wall of the drainage tube 1 and is located between the fixed airbag 3 and the connecting tube 101. The inflation tube 9 is provided with an inflation chamber 1 7 and an inflation chamber 2 8. The inflation chamber 1 7 is used to connect the fixed airbag 3 and the connecting tube 101. The inflation chamber 1 7 is in communication with the inside of the fixed airbag 3, and gas inflates the fixed airbag 3 through the path of connecting tube 101-inflation chamber 1 7-fixed airbag 3.

[0038] An inflation chamber 2 8 is also provided inside the inflation chamber. The inflation chamber 2 8 is used to connect the fixed airbag 3 and the expansion airbag 6. After the gas enters the fixed airbag 3, it inflates the expansion airbag 6 through the path of fixed airbag 3-inflation chamber 2 8-expansion airbag 6.

[0039] By setting up this inflation method, firstly, both airbags can be inflated simultaneously without needing to be operated twice, reducing the number of operation steps; secondly, the gas first enters the fixed airbag 3, and then inflates from the fixed airbag 3 into the expanding airbag 6, making it easier to judge the fullness of the gas in the fixed airbag 3. Since the fixed airbag 3 is located on the inner abdominal wall, it cannot be judged directly. If the fixed airbag 3 is inflated alone, or if the inflation route is to expand the airbag 6 first and then fix the airbag 3, it will be impossible to judge the gas content in the fixed airbag 3. If the gas content is too low, it will not achieve the required limiting function, and if the gas content is too high, it will cause excessive pressure on one or both sides of the abdominal wall, causing discomfort to the patient.

[0040] Medical staff can judge the fullness of the fixed airbag 3 by observing the expanded airbag 6, which makes it easier to replenish gas in time. Furthermore, the fact that the fixed airbag 3 is filled first and the expanded airbag 6 is filled later makes it easier to adjust the fullness of the expanded airbag 6, thereby adjusting the pressure of the negative pressure plate 5.

[0041] The usage process of this utility model is as follows:

[0042] 1. Insert the drainage tube 1 into the puncture hole and adjust its position so that the fixation balloon 3 is located inside the abdominal wall and the expansion balloon 6 is located outside the abdominal wall.

[0043] 2. Connect the syringe through the connecting tube 101 and inflate it. At the same time, observe the expansion bladder 6 to judge the fullness of the fixed bladder 3. Slightly move the drainage tube 1 so that the inner and outer abdominal walls are located between the fixed bladder 3 and the expansion bladder 6, respectively.

[0044] 3. Adjust the pressure of the expanding airbag 6 on the negative pressure plate 5 according to the patient's feelings and actual needs, so as to avoid the patient's discomfort if it is too large, and the negative pressure effect will be not obvious if it is too small.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
