Description

Technical Field

[0001] The invention relates to the technical field of wound dressing treatment, and in particular to a negative pressure electric field dressing. Background Art

[0002] Negative pressure dressing is a common dressing for wound treatment. Its main function is to extract tissue fluid produced by the wound and provide the wound with a closed environment isolated from the outside world to prevent infection by foreign bacteria and make the wound heal better and faster. The stimulation of the electric field also has a rapid healing effect on the wound.

[0003] Negative pressure dressings on the market will adhere to the wound under continuous negative pressure conditions, making it very difficult to replace or remove the dressing. When there is too much tissue exudate on the dressing, the wound will become infected again and the therapeutic effect of the electric field will be weakened. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a negative pressure electric field dressing which is easy to replace, promotes wound healing and improves treatment effects.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A negative pressure electric field dressing comprises a dressing body, the top of the dressing body is covered with a flexible sealing film for sealing and fixing the dressing body on the wound surface, an iodine ion gel layer is arranged below the dressing body, a negative pressure component connected with the dressing body and generating negative pressure is arranged on the flexible sealing film, and an electric field component connected with the iodine ion gel layer and generating an electric field is also arranged on the flexible sealing film.

[0006] As a further improvement of the above technical solution: The negative pressure component includes a suction cup, a negative pressure chamber and a negative pressure tube. The suction cup is arranged on the flexible sealing film and is connected to the dressing body. The negative pressure chamber is arranged on the suction cup and is connected to the negative pressure device through the negative pressure tube.

[0007] The flexible sealing film is provided with a negative pressure hole connecting the dressing body and the suction cup.

[0008] The electric field assembly includes an electrode ring, a conductive member, an electrode sheet and a wire tube. The wire tube is provided with an electrode wire connected to an external power source. The electrode ring is arranged on the periphery between the iodine ion gel layer and the dressing body. The conductive member is embedded in the dressing body and connects the electrode ring and the electrode sheet. The electrode sheet is arranged above the flexible sealing film and connected to the electrode wire in the wire tube.

[0009] The flexible sealing film is provided with an electrode hole for connecting the conductive member and the electrode sheet.

[0010] The conductive member comprises a positive conductive sponge and a negative conductive sponge. The positive conductive sponge connects the electrode ring and the positive electrode sheet in the electrode sheet. The negative conductive sponge is embedded in the middle of the dressing body and connects the iodine ion gel layer and the negative electrode sheet in the electrode sheet.

[0011] The electrode sheet is fixed under the suction cup, and the wire tube is fixedly connected to the negative pressure chamber.

[0012] A plurality of permeation holes are distributed on the iodine ion gel layer.

[0013] A protective film is coated below the iodine ion gel layer.

[0014] Compared with the prior art, the advantages of the present invention are: The present invention extracts exudate from the wound surface through a negative pressure component, and at the same time, an electric field component generates an electric field to promote wound healing. In addition, an iodine ion gel layer is provided and applied on the wound surface. Under the action of the electric field component, iodine ions are introduced into the wound surface, which can not only soften scars and loosen adhesions, but also inhibit the proliferation of bacteria, thereby achieving the effect of eliminating inflammation. Compared with existing negative pressure dressings, adhesion of the dressing to the wound surface can be avoided, reducing the pain caused to the patient during replacement, and the electric field is used to promote the movement of iodine ions into the wound surface, thereby greatly improving the treatment effect.
