Technical Field
[0001] This utility model relates to the field of medical devices, and more specifically, to a surgical wound drainage and fixation device. Background Technology
[0002] During surgical procedures, drainage tubes are often placed in wounds or body cavities to drain accumulated fluids such as pus and blood, thereby preventing postoperative infection and promoting wound healing. However, fixation methods such as suture fixation have problems such as poor safety, unreliable fixation, cumbersome operation, and inconvenience in changing the tubes.
[0003] Drainage devices play a crucial positive role in surgical procedures by effectively draining fluid from wounds or body cavities, reducing the risk of infection, and promoting wound healing. However, in practice, while the combination of drainage devices and gauze enhances the sealing effect, it can also have disadvantages. Excessive sealing may hinder wound ventilation and drying, creating a moist environment that promotes bacterial growth, increasing the risk of secondary infection or suppuration, and potentially causing further harm to the patient.
[0004] Therefore, we made improvements and proposed a surgical wound drainage and fixation device. Utility Model Content
[0005] The purpose of this invention is to address the issue that excessive sealing can hinder wound ventilation and drying, leaving the wound in a moist environment. This, in turn, promotes bacterial growth, increases the risk of secondary infection or suppuration, and may lead to secondary injury to the patient.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0027] As described in the background section, excessive sealing may hinder the ventilation and drying of the wound, leaving the wound site in a moist environment. This, in turn, promotes bacterial growth, increases the risk of secondary infection or suppuration, and may lead to secondary injury to the patient.
[0028] To solve this technical problem, this utility model provides a surgical wound drainage and fixation device, which is used to achieve drainage and protection while ensuring that the patient is not subjected to secondary injury during the drainage process.
[0029] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Surgical wound drainage and fixation devices specifically include:
[0030] The collection box 1 and two symmetrically formed arc-shaped grooves on the collection box 1 conform to the curved surface of the human body. The arc-shaped grooves can better conform to the other side of the injured part of the patient, so that the accumulated fluid can be better collected during the collection process, and damage to the patient's healthy parts can be prevented during the collection process.
[0031] It also includes a slidable bandage 2 that is broken in the middle of the long side of the collection box 1 and complete bandages 2 that are symmetrically arranged on both sides of the broken bandage 2. An elastic band 3 is fixedly connected between the two ends of the broken part of the broken bandage 2. The patient's lesion is fixed through the broken bandage 2 in the middle. At the same time, the end of the middle bandage 2 uses the stretchable elastic band 3 to ensure air circulation through the gap between the elastic band 3 and the bandage 2, thereby ensuring that the patient's wound has good ventilation and that the wound will not suppurate in an anaerobic environment.
[0032] When the broken bandage 2 is parallel or at an angle to the adjacent bandage 2, the elastic band 3 is stretched and suspended above the patient's wound to guide the accumulated fluid. The stretched elastic band 3 is suspended at the wound site, and the water moves on the elastic band 3 using the tension of the water. At the same time, since the two ends of the bandage 2 are set in the collection box 1, the fluid can be better guided into the drainage box 7 and discharged through the catheter 8. At the same time, the elastic band 3 is set in different directions so that it can conform to the wound surface in different directions, avoiding contact with the damaged area.
[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0036] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The surgical wound drainage and fixation device has a broken bandage 2 with its arc-shaped top surface higher than the arc-shaped top surfaces of the two adjacent bandages 2. The cross-section of the bandage 2 is a heart shape with a concave top and a convex bottom. Through the heart-shaped bandage 2, when the wound is flushed with liquid, part of the liquid can stay above the bandage 2 and be guided to the wound by the elastic band 3. The bandage 3 also cleans the sides of the wound, allowing the liquid to come into contact with the wound gradually, reducing the patient's pain.
[0037] Both ends of the disconnected strap 2 are fixedly connected to sliding blocks 4 and locking blocks 5. Both ends of the collection box 1 are fixedly connected to locking plates 6 containing locking slots. The locking plates 6 and locking blocks 5 are on the same plane. The sliding blocks 4 slide on the collection box 1. Through the two sides of the sliding strap 2, the strap 2 in the middle position can be set at different angles, which can better fit the patient's surface.
[0038] The locking block 5 is squeezed by the patient's limb and locked in the slot of the locking plate 6. When the patient's limb enters between the strap 2 and the collection box 1, the length of the strap 2 can be adjusted by the strap part 21 so that the collection device can adapt to different patients. The strap 2 is lifted by the human limb and is squeezed in the locking plate 6 by the locking block 5 to restrict the movement of the inclined strap 2, so that the strap 2 is always at this angle.
[0039] The collection box 1 is provided with three straps 2. Two of the straps 2 are symmetrically arranged at both ends of the collection box 1, pass through the collection box 1 and extend to the other side of the collection box 1 to form a tie section 21. The tie section 21 extends the length of the straps 2, thereby enabling the device to adapt to more trapezoidal patients and keeping the pressure on the patient from the device within a reasonable range.
[0040] The bottom of the collection box 1 is fixedly connected to the liquid guide box 7, and the bottom of the liquid guide box 7 is fixedly connected to the conduit 8. The accumulated liquid is discharged through the liquid guide box 7 and the conduit 8 to avoid secondary infection of pathogens.
