Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a dressing change assembly after drainage tube removal. Background Technology

[0002] Abdominal drainage tube placement is one of the most common surgical procedures in abdominal surgery. Its main principle is to pass the tube through the abdominal wall after abdominal surgery and drain abdominal fluid and blood under negative pressure, reducing the chance of bacterial accumulation in the abdomen. Observing the nature of the abdominal drainage tube can determine whether there is bleeding or infection exudation in the abdominal cavity.

[0003] After the abdominal surgery has healed well, the drainage tube can be removed 2 days post-surgery, depending on the situation. Once the drainage tube sinus tract heals on its own, the abdominal drainage tube removal procedure is considered successful.

[0004] In clinical practice, the following situations may occur after the removal of the abdominal drainage tube: 1) Drainage from the drainage tube sinus tract, which is caused by the sinus tract communicating with the abdominal cavity, allowing ascites or pelvic effusion to leak out. In this case, it is necessary to increase the frequency of wound dressing changes or perform wound suturing to close the sinus tract; 2) The drainage tube may carry bacteria from the abdominal cavity to the abdominal wall layer, leading to infection of the abdominal wall muscles, skin, and soft tissues. (Postoperative patients have low resistance, and the peritoneum's ability to resist bacteria is also reduced due to the damage caused by the drainage tube). In this case, multiple wound dressing changes are required, which involve wiping away pus from the infected wound and applying dressing gauze; wound healing is often slow, increasing the patient's hospital stay and costs, and patient tolerance is poor; 3) Occasionally, bleeding may occur due to rupture of blood vessels in the sinus tract after the drainage tube is removed. Utility Model Content

[0024] The following is a detailed explanation and description of the dressing change assembly after drainage tube removal provided by this utility model, with reference to the accompanying drawings.

[0025] The dressing change assembly after drainage tube removal provided by this utility model can be adjusted according to the wound healing progress. The support rod allows the dressing to be inserted into the wound and even into the peritoneum, enabling better wound disinfection and promoting faster healing. The following detailed description of this utility model is provided in conjunction with specific embodiments:

[0026] In some embodiments, the present invention provides a dressing change assembly after drainage tube removal, such as... Figure 1 , Figure 2 As shown, it includes a support rod 1 and a dressing 2. The support rod 1 includes a support section 11 and a handle. The dressing 2 is wrapped around the support section 11 and is bonded to the support section 11. The support rod 1 is used to provide support for the dressing 2 so that the dressing 2 can be inserted into the wound sinus tract. The dressing 2 includes a cotton gauze layer and an antibacterial coating to sterilize and disinfect the wound.

[0027] In some embodiments, the support rod 1 is a cylindrical structure, with the support section 11 and handle 12 integrally formed. Optionally, it is made of medical-grade plastic and possesses a certain degree of flexibility, allowing for a certain amount of flexible deformation. In this embodiment, the length of the support section 11 is 6cm-10cm, meaning the length of the support section 11 is the same as or slightly greater than the thickness of the abdominal wall, ensuring that the support section 11 can completely penetrate the sinus tracts on the abdominal wall, thereby achieving comprehensive cleaning of the sinus tracts. Optionally, the handle 12 and the support section 11 are also cylindrical structures, or the support section 11 is cylindrical and the handle 12 is flat, making it more convenient for the operator to hold. For example, the handle 12 can be equipped with an anti-slip structure, or the diameter of the handle 12 can be increased, or the handle 12 can be made into a shape that is easy to grip.

[0028] Optionally, the handle 12 is provided with a blocking structure to prevent the handle 12 from entering the sinus tract, thus avoiding excessive insertion of the support rod 1 into the sinus tract and making it difficult to remove. In some embodiments, such as Figure 1 , Figure 2 As shown, the blocking structure includes adhesive tape 3, which is used to adhere to the skin and can play a fixing role to prevent the support rod 1 from entering the sinus tract completely. Optionally, the dressing 2 can extend to the handle 12, and adhesive tape 3 is provided on the dressing 2. When the support section 11 is inserted into the sinus tract, the dressing 2 can be folded so that the adhesive tape 3 adheres to the skin around the wound.

[0029] In some embodiments, such as Figure 3As shown, the blocking structure includes a baffle 3' formed at the handle 12 or at the connection between the handle 12 and the support section 11. The baffle 3' is perpendicular to the handle 12, and its arrangement increases the local cross-sectional area of ​​the handle 12, making it larger than the size of the wound to prevent entry into the sinus tract. Optionally, the baffle 3' can be configured as a ring surrounding the circumference of the handle 12, or it can be configured as a sheet-like structure of other shapes. The baffle 3' is integrally formed with the handle 12, and its thinness provides a certain degree of flexibility to avoid damage to the wound and surrounding skin.

[0030] In some embodiments, the cotton gauze layer includes absorbent cotton, which can be used when there is no bleeding or exudation inside the sinus tract. An antibacterial coating is formed on the surface of the absorbent cotton or absorbed within it. The antibacterial coating disinfects the inner wall of the sinus tract. Optionally, the antibacterial coating is composed of disinfectants such as iodine solution or hydrogen peroxide, and the absorbent cotton absorbs the disinfectant to form the antibacterial coating. The absorbent cotton can absorb moisture, pus, blood, etc., inside the wound sinus tract, while the antibacterial coating wipes the sinus tract wall, cleaning and caring for the wound.

[0031] In some embodiments, the cotton gauze layer includes hydrophobic oily gauze, which can be used when there is bleeding or exudation from the wound. An antibacterial coating is formed on the surface of the hydrophobic oily gauze or is absorbed within the hydrophobic oily gauze. The hydrophobic oily gauze absorbs or covers disinfectants such as iodine and hydrogen peroxide to form an antibacterial coating. Dressing 2 mainly serves to fill and stop bleeding or exudation, and prevent pus from seeping out of the skin.

[0032] Optionally, when bleeding occurs in the wound, hydrophobic oil-based gauze dressing 2 can be used to pack the sinus tract for pressure hemostasis. When there is exudate or even pus in the wound, absorbent cotton dressing 2 can be used to absorb and clean the sinus tract first, and then hydrophobic oil-based gauze dressing 2 can be used to pack the sinus tract to isolate bacterial infection.

[0033] Alternatively, dressing 2 can also be silver ion dressing 2.

[0034] In some embodiments, such as Figure 4 As shown, the dressing 2 and the support rod 1 are separate components. There are various types of dressing 2, and one of these types is assembled with the support rod 1. For example, one support rod 1 can be paired with two dressings 2: one is an absorbent cotton dressing 2, and the other is a hydrophobic oil-based gauze dressing 2. One dressing 2 can be selected and installed on the support rod 1 depending on the wound condition. Optionally, the dressing 2 can be a sheet-like structure with an adhesive layer on one side, allowing it to wrap around and adhere to the support section 11. Alternatively, the dressing 2 can be a cylindrical structure that can be fitted onto the support section 11. Adhesive layers can be provided at one or both ends of the dressing 2 to bond it to the support section 11, effectively preventing the dressing 2 from falling off during use.

[0035] The dressing change assembly provided by this utility model allows the dressing 2 to be inserted into the sinus tract of the wound via a support rod 1 to clean the inner wall of the sinus tract. Different dressings 2 can be selected according to the wound condition to clean and disinfect the inner wall of the sinus tract. Compared with traditional dressing change methods that can only treat the superficial area of ​​the wound, this utility model can effectively avoid wound infection and accelerate wound healing by treating the inside of the sinus tract.
