Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a foam dressing device that can be medicated. Background Technology

[0002] Foam dressings are primarily used for wound protection after dressing changes. Traditional disposable dressings need to be replaced after each dressing change, increasing consumable costs. Furthermore, because the dressings tend to adhere to the wound, tearing them during dressing changes can cause secondary damage to the patient's normal skin and the wound. If a medicated foam dressing could be provided, dressing changes would eliminate the need to tear and replace the dressing; medication could simply be added through the medicated inlet. This would simplify the procedure, reduce the frequency of dressing changes, and minimize secondary damage to normal skin and the wound. Summary of the Invention

[0003] The purpose of this invention is to provide a foam dressing device that can be repeatedly medicated.

[0004] The technical solution for realizing the present invention is as follows:

[0005] A medicated foam dressing device includes a commercially available foam dressing base, a medicated device inserted therein, and a sealing layer. The foam dressing base consists of a water-blocking layer, a foam layer, an adhesive layer, and an anti-adhesion layer in sequence. The medicated device includes a medicated inlet that penetrates the water-blocking layer and the foam layer, and a medicated liquid delivery channel that is inserted into the foam layer.

[0006] The drug delivery channel faces the adhesive layer (wound surface) to facilitate the direct delivery of the drug to the wound surface. The drug delivery channel can be any one or a combination of single or multiple straight, circular, paperclip, or radial channels to facilitate the rapid and uniform delivery of the drug to the wound surface. The drug delivery channel can be a concave guide groove directly made on the surface of the foam layer, or it can be a thin infusion tube with multiple micropores inside it, with the micropores facing the surface of the foam layer.

[0007] The aforementioned drug delivery port can be one or several to facilitate rapid and uniform drug delivery to large areas or long incision wounds.

[0008] The sealing layer is placed above the dosing port to seal the dosing port after dosing.

[0009] When used for the first time, this device is used to cover the wound after changing the dressing, just like ordinary foam dressings. When changing the dressing for the second time, there is no need to tear off the entire foam dressing. Just lift the sealing layer and inject the medication into the medication inlet. The medication can quickly reach the wound through the medication delivery channel. After changing the dressing, seal the medication inlet with the sealing layer to complete the dressing change operation.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This technology eliminates the need to remove or replace the entire foam dressing during secondary dressing changes. Medication can be added simply through the application port to complete the dressing change, saving on consumables and related costs. It also reduces damage to normal skin or wounds caused by tearing the foam dressing during replacement, resulting in a more comprehensive effect that promotes wound healing.

[0012] The invention will be further described below with reference to the accompanying drawings: Attached Figure Description

[0019] Figure 1 This is a schematic diagram of an existing foam dressing structure. The existing foam dressing includes a water-resistant layer 1, a foam layer 2, an adhesive layer 3, and an anti-adhesion layer 4. The water-resistant layer 1 is located on the upper part of the foam layer 2, the adhesive layer 3 is located on the lower part of the foam layer 2, and the anti-adhesion layer 4 is located on the outside of the adhesive layer 3. Traditional dressings need to be replaced after each dressing change, which not only increases the cost of consumables, but also causes secondary damage to the patient's normal skin and wound surface due to the fact that the dressing is easy to stick to the wound and tearing the foam dressing when changing the wound.

[0020] Figure 2The diagram below illustrates Embodiment 1 of the device of the present invention. A medicated foam dressing device includes a commercially available foam dressing base, a medicated dressing device inserted therein, and a sealing layer 5. The foam dressing base consists of a water-resistant layer 1, a foam layer 2, an adhesive layer 3, and an anti-adhesion layer 4. The medicated dressing device includes a medicated inlet 6 penetrating the water-resistant layer 1 and the foam layer 2, and a medicated liquid delivery channel 7 inserted into the foam layer 2. The medicated liquid delivery channel 7 faces the adhesive layer 3 (wound surface) to facilitate direct delivery of medicated liquid to the wound surface. In this embodiment, the medicated liquid delivery channel 7 is radial, or it can be any combination of single or multiple straight, circular, or paperclip types to facilitate rapid and uniform delivery of medicated liquid to the wound surface. The medicated liquid delivery channel 7 can be a concave guide groove directly formed on the surface of the foam layer. The medicated inlet 6 can be one or several to facilitate rapid and uniform medicated liquid delivery to large areas or long incisions. The sealing layer 5 is placed above the medicated inlet 6 to seal the medicated inlet after medicated liquid delivery.

[0021] Figure 3 This is a schematic diagram of embodiment 2 of the device of the present invention. A medicated foam dressing device includes a commercially available foam dressing base, a medicated device inserted therein, and a sealing layer 5. The structure of the commercially available foam dressing base is as follows: Figure 2 The details will not be elaborated here. The drug delivery device includes a drug delivery port 6 that penetrates the water-blocking layer 1 and the foam layer 2, and a drug delivery channel 7 that is inserted into the foam layer 2. The drug delivery channel 7 is made of a drug delivery hose 8, which has multiple micropores 9. The micropores 9 face the surface of the foam layer. When the drug is injected from the drug delivery hose 8, the drug flows from the micropores 9 to the bottom of the foam layer, quickly and evenly delivering the drug to the wound. The drug delivery channel with a drug delivery hose is more suitable for the administration of expensive drugs, which can reduce the absorption of drugs by the foam layer and reduce drug waste.

[0022] Figure 4 This is a schematic diagram of the drug delivery process of the present invention when the sealing layer is opened. When used for the first time, this device is used to cover the wound after changing the dressing, just like ordinary foam dressing. When changing the dressing for the second time, it is not necessary to tear off the entire foam dressing. Just lift the sealing layer 5 and inject the drug into the drug delivery port 6. The drug can quickly reach the wound through the drug delivery channel 7.

[0023] Figure 5 This is a schematic diagram of the sealing layer of the present invention. After the medication is changed, the sealing layer 5 is sealed to cover the medication port 6 to complete the medication change operation.

[0024] This technology eliminates the need to remove or replace the entire foam dressing during secondary dressing changes. Medication can be added simply through the application port to complete the dressing change, saving on consumables and related costs. It also reduces damage to normal skin or wounds caused by tearing the foam dressing during replacement, resulting in a more comprehensive effect that promotes wound healing.
