Description

Medical hydrogel patch capable of fixing drainage tube

Technical Field

The utility model relates to the technical field of medical dressings, in particular to a medical hydrogel dressing capable of fixing a drainage tube.

Background technique

At present, many patients often need to place drainage tubes in the wound after surgery, and the drainage tubes need to be fixed after placement. Conventional drainage tubes are mainly fixed by drainage tube fixing patches, direct tape fixation, or surgical thread passing through the patient's skin and then wrapping around the drainage tube to fix the drainage tube. However, the drainage tube fixing patch is cumbersome to operate, and the firmness and aesthetics of tape fixation are poor. Some patients may also be allergic to tape, resulting in poor fixation of the drainage tube and even the risk of dislocation. Although the drainage tube fixed with surgical thread cannot be dislocated, it is easy to cause the drainage tube to be pulled out when it is pulled, resulting in poor drainage and even slippage, thereby affecting the treatment of the disease and increasing the patient's pain. In addition, the use of sterile patches to stick the open gauze will inevitably stick the drainage tube to the adhesive layer of the patch, making the drainage tube easily crushed or folded, resulting in poor drainage of the drainage tube, seriously affecting the patient's recovery.

Traditional wound dressings, such as bandages and gauze, although effective for dry to mild, exuding wounds, need to be changed regularly, which can cause pain when changing the dressings. In addition, they have poor adhesion properties and cannot provide adequate drainage for the wound. Hydrogel dressings have become one of the most attractive and promising wound dressings due to their considerable moisture retention, biocompatibility and therapeutic properties. Currently, commonly used hydrogel dressings include alginate, gelatin, carboxymethyl cellulose, etc. These dressings can only act on wounds with little exudate due to their general ability to absorb exudate. For wounds with more exudate, the exudate that cannot be absorbed will fail to maintain a sterile environment and cause secondary infection, which never delays healing and leads to complications.

By means of the above structure: when in use, the release paper 4 of the patch is torn off, and the patch is bonded to the drainage tube to fix the drainage tube. The backing layer 1 is made of non-woven fabric, which is non-toxic, non-irritating, moisture-proof, and breathable. It fits the skin around the wound, isolates the hydrogel layer 2 from the outside world, and maintains a sterile environment. In this embodiment, the hydrogel layer 2 is 5 mm thick and is formed by in-situ cross-linking of poly (3, 4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) and chitosan in a certain proportion. It has high biocompatibility, excellent strength, toughness and stability, high antibacterial properties and high water absorption. Because in-situ cross-linking is used in the preparation process, no chemical cross-linking agent and initiator are added, it has low toxicity, and avoids irritation to the skin and causes skin allergies in some patients. The hydrogel will change color when absorbing exudate, which can be used to determine whether it needs to be replaced. The waterproof transparent patch 3 in the middle of the backing layer 1 has a good waterproof effect, isolating the hydrogel layer 2 from the external environment, and visually observing the degree of exudate absorbed by the dressing to determine whether the dressing needs to be replaced. The release paper 4 is 0.5 mm thick and wraps the hydrogel layer 2 with the backing layer 1 to prevent it from being contaminated before use, thereby ensuring the efficacy and viscosity during use.

As shown in FIG4 , a mounting hole 6 is provided in the middle of the outer wall of the backing layer 1, the hydrogel layer 2, and the waterproof transparent patch 3, and a fixing tube 7 is installed on the inner wall of the mounting hole 6. The fixing tube 7 is matched with the mounting hole 6. When the patch is used, the drainage tube is passed through the fixing tube 7 and fixed by the fixing tube 7. The drainage tube can be fixed to avoid slipping, prevent the drainage tube from being poorly fixed, poor drainage, and slipping, and prevent the wound and skin near the drainage tube from contacting the external environment through the gap.

The fixing ring 8 is arc-shaped and is matched with the backing layer 1 and the waterproof transparent sticker 3 respectively. A limiting ring 9 is provided on the outer wall of one side of the fixing ring 8. The limiting ring 9 is matched with the fixing ring 8. A locking ring 10 is provided on the top outer wall of the backing layer 1. The locking ring 10 is matched with the limiting ring 9. The inner wall of the locking ring 10 and the inner wall of the fixing ring 8 are even provided with an anti-slip pad 11.

The locking ring 10 A fixing pin 12 is inserted into the inner wall, and the fixing pin 12 is respectively matched with the locking ring 10 and the limiting ring 9. The outer wall of the fixing pin 12 is covered with a friction pad matched therewith. After the drainage tube is connected to the fixing tube 7, the fixing tube 7 is fixed by the fixing ring 8, so as to fix the drainage tube to prevent the drainage tube from shaking and causing the wound to be exposed. When the fixing ring 8 is fixed, the fixing pin 12 is passed through the locking ring 10 and the limiting ring 9 in turn to fix the fixing ring 8. The operation is simple and easy to use, and it can prevent the drainage tube from shaking and falling off.

How this utility works:

When in use, tear off the release paper 4 of the dressing, and stick the dressing to the drainage tube to fix the drainage tube. The backing layer 1 is made of non-woven fabric, which is non-toxic, non-irritating, moisture-proof, and breathable. It fits the skin around the wound, isolates the hydrogel layer 2 from the outside world, and maintains a sterile environment. The hydrogel layer 2 is formed by in-situ cross-linking, has high antibacterial properties and efficient water absorption, and is low in toxicity, avoiding irritation to the skin and causing skin allergies in some patients. The hydrogel layer 2 will change color when absorbing exudate, which can be used to determine whether it needs to be replaced. The waterproof transparent sticker 3 in the middle of the backing layer 1 has a good waterproof effect, isolating the hydrogel layer 2 from the external environment, and visually observing the degree of exudate absorbed by the dressing to determine whether the dressing needs to be replaced. The release paper 4 and the backing layer 1 wrap the hydrogel layer 2 to prevent it from being contaminated before use, ensuring the efficacy and viscosity during use;

The drainage tube is fixed by the fixing tube 7, so that the drainage tube can be fixed to avoid slipping, prevent the drainage tube from being poorly fixed, poor drainage, and slipping, and prevent the wound and skin near the drainage tube from contacting the external environment through the gap. After the drainage tube is connected to the fixing tube 7, the fixing tube 7 is fixed by the fixing ring 8, so as to fix the drainage tube and prevent the drainage tube from shaking and causing the wound to be exposed. When the fixing ring 8 is fixed, the fixing pin 12 is passed through the locking ring 10 and the limiting ring 9 in turn to fix the fixing ring 8. The operation is simple and easy to use, and the drainage tube can be prevented from falling off due to shaking.
