AI Technical Summary
Existing chest drainage tubes are prone to causing incision leakage during placement, increasing the risk of infection, patient suffering, and workload for medical staff, and may require secondary suturing.
Design a drainage bag to prevent surgical site infection, comprising a drainage bag body, an anti-reflux sheet, and an antibacterial base plate. Exudate flows directly into the anti-reflux bag through the anti-reflux port, avoiding contact between the incision skin and the exudate. Combined with the antibacterial base plate, the chance of infection is reduced.
It effectively avoids incision infection, improves patient comfort, reduces the frequency of dressing changes, reduces patient anxiety, reduces the workload of medical staff, and keeps the incision skin clean.

Abstract
Description
Technical Field
[0001] This utility model relates to a drainage bag, specifically a drainage bag that prevents surgical site infection, and belongs to the technical field of medical devices. Background Technology
[0002] Lung cancer is currently the leading cause of cancer death worldwide. Early-stage lung cancer patients can be treated surgically, which often involves the placement of a chest drainage tube. This tube needs to drain both air and fluid, making accurate placement crucial. Some patients experience significant postoperative air leakage due to severe pulmonary adhesions, requiring prolonged chest drainage and increasing the risk of incision drainage. Incision drainage presents several problems: firstly, it increases the risk of infection; secondly, it necessitates frequent dressing changes, increasing workload and wasting medical resources; and thirdly, in some cases, significant drainage may require secondary suturing, substantially increasing patient suffering.
[0003] Therefore, developing a drainage bag that is resistant to surgical site infection is a technical problem that urgently needs to be solved in this field. Utility Model Content
[0004] In view of the above-mentioned technical problems of the prior art, the purpose of this utility model is to provide a drainage bag that prevents surgical site infection. Its special structural design allows exudate to flow directly into the anti-backflow port, keeping the patient's surgical site skin clean and effectively preventing surgical site infection.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0006] A drainage bag for preventing surgical site infection includes a drainage bag body, which comprises a first piece and a second piece. The outer periphery of the first piece and the second piece are closed to form a drainage bag. A drainage tube is provided at the outlet of the drainage bag, and an anti-backflow piece is provided between the first piece and the second piece. The anti-backflow piece is connected to the first piece to form an anti-backflow bag, and the anti-backflow bag has an anti-backflow port. A base is provided on the back of the second piece. A drainage tube insertion port is provided at the center of the base, and the base is provided with a plurality of guide lines. The plurality of guide lines form concentric circles with the drainage tube insertion port as the center.
[0007] A third piece is provided on the back of the second piece, and the chassis is provided on the back of the third piece.
[0008] The reference line has a radius dimension, which is 15-55mm.
[0009] The chassis is an antibacterial chassis.
[0010] The beneficial effects of this utility model are as follows:
[0011] This utility model of drainage bag for preventing surgical site infection has an antibacterial base plate that reduces the chance of infection compared to ordinary gauze; and exudate flows directly into the anti-reflux bag through the anti-reflux port, improving comfort, avoiding secondary suturing, reducing patient anxiety, keeping the patient's surgical site skin clean, avoiding dressing changes, and greatly reducing the workload of medical staff.

Detailed Implementation
[0017] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.
[0018] like Figure 1-6 As shown, this utility model discloses a drainage bag for preventing surgical site infection, comprising a drainage bag body 1. The drainage bag body 1 includes a first piece 11 and a second piece 12. The outer peripheries of the first piece 11 and the second piece 12 are closed to form a drainage bag. An outlet tube 2 is provided at the outlet of the drainage bag, and an anti-backflow piece 13 is provided between the first piece 11 and the second piece 12. The anti-backflow piece 13 is connected to the first piece 11 to form an anti-backflow bag, and the anti-backflow bag has an anti-backflow port 15. Exudate flows directly into the anti-backflow bag through the anti-backflow port 15, improving comfort, avoiding secondary suturing, reducing patient anxiety, keeping the patient's surgical site skin clean, avoiding dressing changes, and greatly reducing the workload of medical staff.
[0019] Furthermore, to further improve patient comfort, the back of the second piece 12 in this invention is provided with a third piece 14, and the back of the third piece 14 is provided with a base 3. The center of the base 3 is provided with a drainage tube insertion port 31, and the base 3 is an antibacterial base, which reduces the chance of infection compared with ordinary gauze.
[0020] Furthermore, for greater ease of use, the chassis 3 of this invention is provided with several guide lines 32. These guide lines 32 form concentric circles with the drainage tube insertion port 31 as the center. The guide lines 32 have a radius dimension, which is 15-55mm, such as 15mm, 25mm, 35mm, 45mm, or 55mm. When using it, the diameter of the drainage tube insertion port 31 can be selected according to actual needs, and it can be cut along the guide lines 32 using scissors or other techniques.
[0021] The unique structural design of this invention allows exudate to flow directly into the anti-backflow port 15, keeping the patient's incision skin clean and effectively preventing infection of the incision.
[0022] The above embodiments are only used to explain the inventive concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
