Description

Technical Field

[0001] This utility model belongs to the field of medical dressings, and specifically relates to a pressure dressing with anti-seepage liquid. Background Technology

[0002] Traditional medical dressings have several shortcomings in dealing with drainage tube leakage. While ordinary gauze has some absorbency, it is difficult to apply it tightly to the skin, especially at the point where the drainage tube exits. It is hard to form an effective seal, and bodily fluids can easily leak through the gaps between the gauze and the skin. This not only keeps the skin around the wound in a moist environment for a prolonged period, increasing the risk of infection, but it can also soak the patient's clothing and bedding, causing significant inconvenience and discomfort.

[0003] To address this issue, some medical staff attempted to apply ordinary adhesive film over the gauze. However, due to the unique location of the drainage tube, the film was difficult to adhere completely and could not apply sufficient pressure to the gauze, thus failing to fundamentally stop the leakage. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a leak-proof pressure dressing. By inflating a semi-circular air bladder to generate compression force, combined with a transparent adhesive film, it allows double-layered gauze to adhere tightly to the skin, effectively preventing fluid leakage. Compared to traditional dressings that rely solely on an adhesive film for fixation, this design significantly enhances the tightness of the fit between the dressing and the skin, especially at the point where drainage tubes pass through, creating a good seal and significantly reducing the risk of leakage.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A pressure dressing for preventing leakage includes gauze, wherein the gauze is a double-layered gauze, and a semi-circular airbag is installed inside the double-layered gauze. The semi-circular airbag is connected to an air tube, and the air tube is connected to an air nozzle. When the semi-circular airbag is inflated, it is sealed by a sealing component. Preferably, the semi-circular airbag is fixed inside the double-layer gauze by stitching.

[0006] Preferably, the semi-annular airbag has a U-shaped structure, and the central area of ​​the semi-annular airbag is used to cover the wound site.

[0007] Preferably, the closure is a one-way valve or a binding rope; When the sealing element is a one-way valve, the one-way valve is installed at the air nozzle. The one-way valve is used to ensure that gas can only enter the semi-annular air bag from the air nozzle. When the closure is a tie, the tie is used to secure the trachea.

[0008] Preferably, the double-layer gauze is used in conjunction with an adhesive, which is a transparent adhesive film, tape, or adhesive paper.

[0009] Preferably, the trachea is a medical flexible tube, and the nozzle is adapted to fit the syringe head.

[0010] Preferably, the double-layer gauze has a hydrocolloid layer on both the upper and lower surfaces.

[0011] The present invention can achieve the following beneficial effects: 1. The expansion of the semi-circular air bladder generates compression force, which, combined with the transparent adhesive film, allows the double-layer gauze to adhere tightly to the skin, effectively preventing fluid leakage. Compared to traditional dressings that rely solely on the adhesive film for fixation, this design significantly enhances the tightness of the fit between the dressing and the skin, especially at the point where the drainage tube exits, creating a good seal and significantly reducing the risk of leakage.

[0012] 2. The semi-circular airbag adopts a U-shaped, "C"-shaped, or unclosed curved structure. The central area covers the wound, and the unclosed part provides space for the drainage tube to pass through. This satisfies the wound coverage requirement while fully considering the actual situation of drainage tube placement. At the same time, a gap is reserved between the suture and the edge of the semi-circular airbag to provide space for the airbag to inflate and ensure that the airbag can exert its compression effect normally.

[0013] 3. The endotracheal tube uses medical-grade tubing, and the nozzle is compatible with the head of a 2-5mL medical syringe. Only a small amount of gas needs to be injected into the semi-circular airbag, making the operation simple and easy for medical personnel to master. Furthermore, the inflation principle of the semi-circular airbag is similar to that of a swimming ring, and the one-way valve can borrow the structural design of a swimming ring's one-way valve, which helps reduce production costs. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of the structure of a leak-proof pressure dressing in Example 1; Figure 2 This is a cross-sectional view of a leak-proof pressure dressing in Example 1; Figure 3 This is a cross-sectional view of a pressure dressing with impermeable liquid in Example 2.

[0015] In the diagram: 1. Double gauze; 2. Semi-circular airbag; 3. Trachea; 4. Air nozzle; 5. Wound location; 6. One-way valve; 7. Transparent adhesive film; 8. Hydrocolloid layer; 9. Drainage tube; 10. Suture. Detailed Implementation

[0016] Example 1: Preferred solutions include Figure 1 Figure 2As shown, a pressure dressing for preventing leakage includes gauze, which is a double-layered gauze 1. A semi-circular airbag 2 is installed inside the double-layered gauze 1. The semi-circular airbag 2 is connected to an air tube 3, and the air tube 3 is connected to an air nozzle 4. When the semi-circular airbag 2 is inflated, it is sealed by a sealing component. The main innovation of this utility model is that it uses the compressive force generated by the expansion of the semi-circular airbag 2 to adhere the double-layered gauze 1 to the skin. The specific solution is as follows: like Figure 1 As shown, the semi-circular airbag 2 is fixed inside the double-layer gauze 1 by suturing. Sutures 10 are sewn along both edges of the semi-circular airbag 2 to confine it within a certain area. The sutures 10 have a certain distance from the edge of the semi-circular airbag 2, the purpose of which is to provide sufficient expansion space when the semi-circular airbag 2 is inflated.

[0017] Since medical dressings are used in conjunction with adhesive films, which are used to adhere the medical dressing to the skin, the adhesive film is generally a transparent adhesive film 7. When the transparent adhesive film 7 adheres the entire medical dressing to the skin, the semi-circular air bladder 2 only needs to be inflated with a small amount of gas to exert a squeezing effect, which can improve the adhesion between the double-layer gauze 1 and the skin and prevent leakage of body fluids.

[0018] Furthermore, the semi-annular airbag 2 has a U-shaped structure, with the central area of ​​the semi-annular airbag 2 used to cover the wound location 5. The unclosed portion of the semi-annular airbag 2 provides space for the drainage tube 9 to pass through. Based on the design concept of this utility model, the semi-annular airbag 2 in a "C" shape or an unclosed curved shape is within the protection scope of this utility model.

[0019] Furthermore, the sealing element is a one-way valve 6 or a binding rope; the sealing element is mainly to prevent gas leakage from the semi-annular airbag 2, and designs based on this principle are all within the protection scope of this utility model.

[0020] When the sealing element is a one-way valve 6, the one-way valve 6 is installed at the air nozzle 4. The one-way valve 6 is used to ensure that gas can only enter the semi-annular air bag 2 from the air nozzle 4. When the closure is a rope, the rope is used to secure the air tube 3.

[0021] Furthermore, the double-layer gauze 1 is used in conjunction with an adhesive patch, which is a transparent adhesive film 7, tape, or adhesive paper. The adhesive patch is a standalone medical consumable, generally used in conjunction with gauze, hydrocolloids, etc., primarily to adhere the medical dressing to the skin.

[0022] Furthermore, the trachea 3 is a medical-grade flexible tube, and the nozzle 4 is designed to fit the syringe head. A 2-5 mL medical syringe is sufficient; only a small amount of gas needs to be injected into the semi-circular air bladder 2.

[0023] The working principle of this utility model: Double gauze 1 is used to cover the wound site 5. At this time, the semi-circular air bladder 2 surrounds the wound. The transparent adhesive film 7 is used to attach the double gauze 1 to the patient's skin. After the double gauze 1 is attached to the skin, air is inflated into the semi-circular air bladder 2. After the semi-circular air bladder 2 expands, it is simultaneously restrained by the transparent adhesive film 7, so that the double gauze 1 will adhere tightly to the skin.

[0024] In this embodiment, the component used to inflate the semi-annular airbag 2 is a syringe without a needle. The syringe introduces air into the semi-annular airbag 2, and due to the action of the one-way valve 6, the gas inside the semi-annular airbag 2 will not leak out.

[0025] The inflation principle of the semi-circular airbag 2 is similar to that of a swimming ring, and the one-way valve 6 can also adopt the one-way valve structure design of a swimming ring to reduce production costs. This drainage tube's leak-proof pressure dressing is a disposable consumable; after use, it should be disposed of entirely in the medical waste bin.

[0026] Example 2: Based on Example 1, this example mainly adds a hydrocolloid layer 8 to improve the absorbency of the dressing.

[0027] like Figure 3 As shown, the double-layer gauze 1 has a hydrocolloid layer 8 on both the upper and lower surfaces.

[0028] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
