Description

Technical Field

[0001] The invention relates to the technical field of medical dressings, in particular to a novel drainage tube port anti-seepage dressing. Background Art

[0002] In clinical practice, especially in the field of surgery, more than 80% of surgical operations require the placement of drainage tubes to achieve the purpose of early postoperative adequate drainage, observation of patient recovery, and reduction of postoperative complications. After the exudation of the wound surface is reduced to a certain extent, the drainage tube is removed. Clinicians often use cotton pads or square gauze pressure bandages to cover the drainage tube opening. The continuous exudation of drainage fluid from the drainage tube opening not only increases the difficulty and workload of doctors in wound dressing changes, but also increases the pain of repeated dressing changes for patients, delayed healing of the drainage tube opening, and infection risks. The current impermeable dressings mostly use a three-layer design (from inside to outside) of a one-way permeable membrane, a water-absorbing sponge layer, and a waterproof membrane. The main reason is that after the exudate is absorbed by the water-absorbing sponge layer, a tightening pressure is generated to enhance the fit. For example, after the exudate enters, it will be absorbed by the water-absorbing sponge layer, and its expansion will generate a pressure on the attached dressing patch, which plays a role in enhancing the fit and preventing more water from entering. The water that enters the dressing patch is blocked by the one-way permeable membrane and will not contact the wound.

[0003] However, this direct pressurization and anti-seepage method has a certain effect on exposed wounds, but has little effect on exudation from internal wounds such as drainage tube orifices. At the same time, in the early stage of drainage tube removal, when there is a lot of exudate from the drainage tube orifices, a large amount of absorbent dressings are used clinically for replacement, which further increases the economic burden on patients.

[0004] To this end, we have developed a new type of drainage tube impermeable dressing. Summary of the invention

[0035] The rubber band 7 includes a buckle end 701, a connecting middle section 702 and a movable end 703. The buckle end 701 and the connecting middle section 702 are fixedly connected to the side wall of the adhesive tape 8. One end of the buckle end 701 is fixedly connected to one end of the connecting middle section 702, and the movable end 703 is fixedly connected to the other end of the connecting middle section 702. The rubber band 7 made of rubber material can be deformed to a certain extent, so as to better adapt to the function of clamping the outer surface of the drainage tube.

[0036] The contraction limiting mechanism includes a rotating shaft 12 which penetrates and is rotatably connected to one end of the movable end 703. A C-shaped buckle 13 is fixedly connected to the outer surface of the rotating shaft 12, and a plurality of limiting grooves 16 matching the C-shaped buckle 13 are provided on the inner side of the buckle end 701, that is, the C-shaped buckle 13 can be clamped on the inner wall of the limiting groove 16, thereby fixing the position of the C-shaped buckle 13 and the movable end 703;

[0037] Correspondingly, the shrinkage limit mechanism also includes a makeshift groove 15 respectively opened in the middle of the side wall of the buckle end 701 and a slide groove 14 opened at the top and bottom of the side wall of the buckle end 701. The depth of the makeshift groove 15 matches the thickness of the movable end 703, the width of the slide groove 14 matches the diameter of the rotating shaft 12, and the movable end 703 enters the inside of the side wall of the buckle end 701 by inserting into the makeshift groove 15, and the rotating shaft 12 extends to the outside of the buckle end 701 by passing through the slide groove 14.

[0038] The lower surface of the first plastic hard shell 1 is fixedly connected with the first absorbent sponge pad 9, the lower surface of the second plastic hard shell 6 is fixedly connected with the second absorbent sponge pad 10, and the lower surfaces of the buckle end 701 and the connecting middle section 702 in the rubber band 7 are jointly fixedly connected with the annular absorbent sponge pad 11, and the areas of the first absorbent sponge pad 9 and the second absorbent sponge pad 10 correspond to and are equal to the areas of the first plastic hard shell 1 and the second plastic hard shell 6 located above, respectively, and the area of ​​the annular absorbent sponge pad 11 is equal to the sum of the areas of the buckle end 701 and the connecting middle section 702 in the rubber band 7. The material of the absorbent sponge can quickly absorb a small amount of drainage fluid exuded from the surface of the incision after the patient's drainage operation.

[0039] Working principle:

[0040] When using the new drainage tube port seepage-proof dressing, first, after removing the drainage tube, clean the area around the drainage tube port, align the empty area in the middle of the dressing (i.e., the notch in the middle of the rubber band 7) with the position of the drainage tube port wound, and stick the adhesive tape on the skin. After the adhesive tape 8 is attached to the skin around the drainage tube port, pull the self-locking nylon plastic tie strips 5 on both sides at the same time (pull the self-locking nylon plastic tie strips 5 at both ends to the left and right sides respectively). The opposite pulling force will automatically bring the lower skin closer together, and the drainage tube port can be automatically tightened by the tension of the skin itself to avoid continuous seepage of drainage fluid, while ensuring the air permeability of the drainage tube wound, preventing bacterial infection, and promoting the healing of the drainage tube port. In addition, because the bottom layer close to the skin is a water-absorbing sponge, a small amount of drainage fluid exuded from the surface can be quickly absorbed;

[0041] Because the tape has a certain elasticity, when it is subjected to external tension, it will generate an internal contraction force, which will make it stick more firmly to the skin and dressing. The exudate at the edge of the wound can also be quickly absorbed by the absorbent sponges on both sides, ensuring that the drainage tube opening is dry and clean.

[0042] Furthermore, after the drainage tube passes through the notch in the middle of the rubber band 7, the movable end 703 can be pinched to be inserted into the yield groove 15 of the buckle end 701, thereby tightening the notch of the rubber band 7 to better fit the size of the drainage tube, and gently turning the rotating shaft 12 so that the side of the C-shaped buckle 13 is stuck on the inner wall of the limiting groove 16 at the appropriate position, and the position of the movable end 703 inserted into the buckle end 701 can be locked, that is, the rubber band 7 is locked so that it is tightened and fits the outer wall of the drainage tube, so that the annular absorbent sponge pad 11 below it can better block the gap between the drainage tube and the patient's surgical incision and absorb the exudate. The exudate at the edge of the wound can also be slowly transmitted to the first absorbent sponge pad 9 through the annular absorbent sponge pad 11 and the second absorbent sponge pad 10 to be absorbed, and the situation where the exudate wets the tape 8 and causes it to fail quickly is avoided.

[0043] To summarize, the present application mainly starts from the source of exudate. The bottom layer of its plastic hard shell is an absorbent sponge. After the absorbent dressing adheres to the skin surface, the drainage tube opening is pulled together through external pulling force and the tension of the skin itself, which not only ensures a certain water absorption effect of the dressing, but also reduces exudate from the drainage tube opening, avoids contamination of the surgical incision, and accelerates the healing of the drainage tube opening. Excess light exudate will be absorbed by other tissue structures of the body and then discharged from the body (peritoneum, greater omentum, etc. can absorb exudate and discharge it through urine, sweat, etc.).

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
