Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and more particularly to a manual antibacterial negative pressure flushing integrated dressing. Background Art
[0002] In the field of wound treatment, negative pressure drainage technology promotes wound healing by creating a negative pressure environment, and is an effective means commonly used in clinical practice. However, most existing dressings only have a single negative pressure drainage function and lack the ability to flush simultaneously, resulting in the need for additional external flushing equipment during treatment, and the operation steps are cumbersome and inefficient. Traditional dressings have limited antibacterial properties and cannot inhibit bacterial growth for a long time; the design of flushing and drainage pipes is unreasonable, resulting in uneven distribution of flushing fluid and insufficient drainage, which affects the wound healing effect. In addition, existing dressings and drainage pipes mostly adopt fixed connections or disposable designs, and the hose assemblies cannot be reused, resulting in waste of medical consumables and increased treatment costs. At the same time, the drainage tube lacks a reliable non-return structure, and there is a risk of infection caused by liquid backflow.
[0003] Therefore, there is an urgent need for a reusable dressing device that integrates flushing and negative pressure drainage functions, contains antibacterial functions, has an efficient pipeline structure, and can solve the problems of functional separation, inconvenient operation, high cost, and insufficient safety in the existing technology.

[0031] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this patent.
[0032] Please see the attached Figure 1-4 , a manual antibacterial negative pressure flushing integrated dressing disclosed in the present invention, comprising: a dressing 1, a sticker 3 and a hose assembly 5; the dressing 1 contains a silver ion component and is provided with a pipe 2 inside; the sticker 3 is provided with a connector 4; the connector 4 is detachably connected to the hose assembly 5 through a valve 10; the hose assembly 5 includes a valve 10, and the valve 10 is connected to a drainage tube 7 and a flushing tube 8 that are in communication with each other, and the flushing tube 8 is provided with a valve for controlling the opening and closing of the flushing tube 8 channel.
[0033] The sticker 3 is made of transparent material, and the sticker 3 fixes the dressing 1 in the wound, making it easier for medical staff to observe changes in the patient's wound.
[0034] The dressing 1 is made of polyurethane sponge containing silver ions. The dressing 1 containing silver ions can continuously release antibacterial ions, and combined with negative pressure suction, it can reduce bacterial colonization and achieve antibacterial and anti-inflammatory effects. The pipes 2 inside the dressing 1 are branched from the main pipe into a multi-layer mesh interlaced structure, and the main pipe is located at the center of the surface. This design allows the flushing fluid to be evenly distributed to the entire wound covered by the dressing 1 through the multi-layer mesh pipe. Even if the dressing 1 is cut according to the shape of the wound, the remaining part of the pipe 2 can still remain connected, without affecting the flushing and negative pressure suction functions, ensuring the effectiveness and flexibility of the treatment.
[0035] The flushing pipe 8 is provided with a valve, the valve core of which can be a plate valve or a ball valve, and the opening and closing of the flushing pipe 8 channel is controlled by rotating the rotating shaft through the switch.
[0036] In order to further optimize the above technical solution, a quick-connect pipe 6 is provided between the sticker 3 and the hose assembly 5. The quick-connect pipe 6 is provided with two cavities, which are respectively connected to the drainage pipe 7 and the flushing pipe 8. Quick connectors are provided at both ends of the quick-connect pipe 6, which are detachably connected to the connector 4 and the valve 10.
[0037] In order to further optimize the above technical solution, the drainage tube 7, flushing tube 8 and quick-connect tube 6 are internally provided with a one-way check valve 12, which is preferably made of medical silicone with a thickness of 0.3 mm and a three-petal radial incision. It can only be opened by strong water flow impact or strong air pressure suction to achieve a check effect.
[0038] The check valve 12 can effectively prevent backflow of liquid during drainage, avoid secondary contamination of the wound surface, and ensure the safety of treatment. When there is strong air pressure (negative pressure) or strong water flow in the drainage tube 7, the thin flaps are affected by the pressure and open to both sides, allowing liquid to pass through. When there is no pressure or the pressure is reversed, the thin flaps return to their original state due to their resilience and close to a closed state, preventing backflow of liquid, thereby achieving a check effect and ensuring the safety of the drainage process.
[0039] To further optimize the above technical solution, the dressing 1 is made of a cuttable material. The internal conduit 2 branches from a main conduit into multiple layers of interlaced, meshed conduits. The main conduit is positioned at the center of the surface of the dressing 1. The dressing 1 is constructed from a honeycomb sponge, with the conduits 2 pre-embedded within it. The dressing 1 is trimmed to the shape of the wound, ensuring that the main conduit is aligned with the center of the wound.
[0040] In order to further optimize the above technical solution, the open end of the flushing tube 8 is provided with a flushing head, which can be snapped onto the mouth of the bag filled with liquid, so as to connect the flushing liquid bag conveniently and quickly without the need for additional connection tools and is easy to operate.
[0041] In order to further optimize the above technical solution, the end of the drainage tube 7 is a drainage port, and a negative pressure drainage bag 9 is provided near the drainage port to store the liquid sucked out by negative pressure. Medical staff can regularly observe or pour out the liquid in the negative pressure drainage bag 11 to understand the condition of the wound in a timely manner.
[0042] In order to further optimize the above technical solution, the connector 4 is provided with a buckle or thread, which can be quickly assembled and disassembled with the quick connector or valve 10 through the buckle or thread, so that medical staff can quickly replace the hose assembly 5, quick tube 6 or adjust the dressing 1 during treatment, saving operation time.
[0043] To further optimize the above technical solution, the valve 10 is provided with a valve switch, which is connected to an internal baffle 13 via a connecting rod. Rotating the valve switch controls the rotation of the baffle 13, thereby controlling the opening and closing of the drainage tube 7 and the flushing tube 8. The valve switch is a rotary knob, and the connecting rod drives the baffle 13 to rotate within a 90° range.
[0044] During operation, opening and closing the valve 10 can not only control the outflow of the flushing liquid, but also reversely flush the drainage tube 7 through the flushing tube 8 when necessary to remove the residual liquid and impurities in the drainage tube 10, so that the hose assembly 5 can be reused by the same person, reducing the waste of medical consumables and lowering treatment costs.
[0045] To use, first place the cut dressing 1 over the wound surface and secure it with the sticker 3. Then, connect the valve 10 on the hose assembly 5 to one end of the quick-connect pipe 6, and the other end of the quick-connect pipe 6 to the connector 4 on the sticker 3. Then, snap the flushing head of the flushing tube 8 onto the opening of the bag containing the flushing fluid, and connect the drain port at the end of the drainage tube 7 to a negative pressure drain. Open the valve on the flushing tube 8 and the valve 10 on one end of the hose assembly 5. With the baffle 13 perpendicular to the tube wall, the passage is open, and the flushing fluid flows from the bag through the flushing head, flushing tube 8, quick-connect pipe 6, and connector 4 into the pipe 2 inside the dressing 1, flowing through the pipe 2 to flush the wound surface.
[0046] After flushing is completed, close the valve on the flushing tube 8, start the negative pressure device, and form negative pressure in the hose assembly 5. The liquid on the wound surface and the waste liquid after flushing enter the drainage tube 10 through the connector 4 and the quick connector 6, and flow to the negative pressure drainage bag 9 for storage through the check valve 12. The tough thin sheet of the check valve 12 opens under negative pressure suction and closes after the suction is completed to prevent the liquid from flowing back.
[0047] After the negative pressure drainage is completed, close the valve 10, remove the quick-connect pipe 6 and the hose assembly 5 from the sticker 3, discard the quick-connect pipe 6, remove the bag of flushing liquid on the flushing head and replace it with a bag filled with disinfectant, close the valve on the flushing pipe 8 and the valve 10 at one end of the hose assembly 5, start the negative pressure device, form negative pressure in the hose assembly 5, and the liquid and disinfectant on the wound enter the drainage pipe 7 through the flushing pipe 8, and flow to the negative pressure drainage bag 9 for storage through the check valve 12, completing the flushing and disinfection of the hose assembly 5. After the disinfection is completed, the hose assembly 5 can be reused by the same person.
