Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a device for preventing leakage of injected liquid for local skin sealing. Background Art

[0002] In the medical field, local skin block injection is a common treatment method, widely used in the treatment of various diseases, such as pain management, control of local inflammation, etc. However, when performing local skin block injection, the problem of liquid exudation often brings troubles to treatment. Traditional treatment methods are often relatively simple, such as using ordinary gauze or bandages for covering, but these methods have many shortcomings. The absorption capacity of gauze is limited, which easily leads to the accumulation of exudate at the injection site, increasing the risk of infection. The bandage has poor fixation effect and is easy to shift, and cannot effectively prevent liquid exudation. In addition, some existing anti-exudation measures may cause greater irritation to the patient's skin, causing discomfort or even allergic reactions. Moreover, these methods are often not convenient in operation, which increases the difficulty and time cost of medical staff. Therefore, we introduce a new anti-exudation device for local skin block injection of liquid. Utility Model Content

[0008] By adopting the above technical solution, the transparent layer makes it easy to observe the condition of the adhesive layer before use to check whether there is contamination or damage.

[0009] Preferably, the hydrocolloid dressing block is located on the left side of the mesh body.

[0010] By adopting the above technical solution, it is ensured that the exudate is first initially blocked and dispersed by the mesh body and then absorbed by the hydrocolloid dressing block, thereby improving the absorption efficiency and effect.

[0012] By adopting the above technical solution, the release layer can be easily torn off during use to expose the adhesive layer for the adhesive operation.

[0014] By adopting the above technical solution, the adhesive layer can be fully protected, the adhesiveness of the adhesive layer is not affected by the outside world, and the firmness and stability of the adhesive are guaranteed.

[0015] Preferably, the sealing pad and the hydrocolloid dressing piece are an integral structure.

[0016] By adopting the above technical solution, the hydrocolloid dressing block is prevented from shifting or falling off during use, thereby ensuring the anti-exudation effect.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] See also Figure 1-4 , the utility model provides a technical solution:

[0029] A device for locally sealing the skin to prevent the leakage of injected liquids, comprising a sealing pad 1, a cavity 5 being defined in the middle of the right end of the sealing pad 1, an adhesive layer 4 being fixedly connected to the periphery of the right end of the sealing pad 1, a tearing device 2 being bonded to the right end of the adhesive layer 4, an absorbent device 3 being filled in the cavity 5, and a mesh 6 being fixedly connected to the middle of the right end of the sealing pad 1;

[0030] The sealing pad 1 and the hydrocolloid dressing piece 32 are integrally formed.

[0031] In this embodiment, the absorption device 3 includes a hydrocolloid dressing block 32 , the outer surface of which is fixedly connected to the elastic layer 31 , and the hydrocolloid dressing block 32 fills the cavity 5 ; the hydrocolloid dressing block 32 is located on the left side of the mesh 6 .

[0032] Through the above scheme: after a local closed injection of the skin, if there is liquid exudation, the hydrocolloid dressing block 32 located on the left side of the mesh body 6 will quickly absorb the exudate due to its good water absorption, and the elastic layer 31 on the outer surface of the hydrocolloid dressing block 32 can make the dressing block better fit the shape of the cavity 5, fully contact with the exudate, and improve the absorption efficiency. The hydrocolloid dressing block 32 can quickly and effectively absorb the exudate and keep the injection site dry. In some injection operations with frequent exudate, it can continue to play a good absorption role. The elastic layer 31 enables the absorption device 3 to adapt to cavities 5 of different shapes and sizes, ensuring that the absorption effect is not affected by the difference in the shape of the device, absorbing the exudate in time, avoiding long-term contact of the liquid with the skin, and reducing irritation and damage to the skin.

[0033] In this embodiment, the tearing device 2 includes a release layer 21, a transparent layer 23 is fixedly connected to the middle of the right end of the release layer 21, a tear strip 22 is fixedly connected to the lower front end of the release layer 21, and the release layer 21 is bonded to the right end of the adhesive layer 4; the release layer 21 and the adhesive layer 4 are in a detachable adhesive structure; the size of the release layer 21 is the same as the size of the adhesive layer 4.

[0034] Through the above solution: by grasping the tear strip 22 at the lower front end of the release layer 21, the release layer 21 is torn off from the adhesive layer 4, thereby exposing the adhesive layer 4, making it convenient to stick the closure pad 1 to the injection site of the skin. The design of the tear strip 22 makes the operation of removing the release layer 21 simple and quick, saving preparation time. The transparent layer 23 in the middle of the right end of the release layer 21 allows the user to observe the condition of the adhesive layer 4 before removing the release layer 21 to ensure that it is not damaged or contaminated. The release layer 21 is the same size as the adhesive layer 4, which can fully and evenly protect the viscosity of the adhesive layer 4 and improve the stability and reliability of the adhesion.

[0035] It should be noted that the present invention is a device for preventing liquid exudation from being injected into the skin for local closure. During use, first, before performing local closure injection of the skin, the release layer 21 is torn off from the adhesive layer 4 by the tearing strip 22 of the tearing device 2. Then, the closure pad 1 is pasted on the skin of the injection site through the adhesive layer 4 to make it fit tightly. During the injection process, when liquid exudates, the mesh 6 can play a certain blocking and dispersing role to prevent the exudate from directly spreading over a large area. The hydrocolloid dressing block 32 in the absorption device 3 located in the cavity 5 can quickly absorb the exudate due to its own characteristics. The elastic layer 31 on the outer surface of the hydrocolloid dressing block 32 It can provide a certain degree of elasticity and cushioning, which helps to better adapt to the morphology of the skin surface and enhance the absorption effect. When the injected drug is a certain irritant and liquid seeps out, the device can absorb it in time to avoid the drug from irritating and damaging the surrounding skin. When the injection site needs to be kept dry for a long time, this device can continuously absorb the exudate and maintain the dry state of the local skin, which is beneficial to the recovery of the wound and the protection of the treatment effect. In general, this anti-exudation device effectively prevents the leakage of liquid during local skin closure injection through the synergistic effect of adhesive fixation, mesh 6 blocking, and hydrocolloid dressing block 32 absorption, providing better protection for treatment.
