Problems solved by technology

However, when negative pressure and strong oxygen are combined, there will be air pressure conflicts. Under negative pressure, the dressing will stick to the wound surface, but under high pressure, the dressing will move in the opposite direction and leave the wound surface. It is difficult to combine the two, and most of the existing dressing equipment only has one treatment Function, patients can only carry out various treatment plans through different equipment when undergoing treatment, the operation is cumbersome and the treatment time is prolonged

Embodiment 1

[0027] Such as figure 1 As shown, the negative pressure electric field coupled strong oxygen therapy dressing of this embodiment includes a first film layer 1 covering the wound surface and the wound edge, and the first film layer 1 provides a closed environment for the wound surface to prevent external bacterial infection. It also includes an electric field device 3 for applying an electric field to the wound. The electric field device 3 includes a positive electrode 31 arranged at the edge of the wound, a negative electrode 32 arranged at the center of the wound, and a power supply for the positive electrode 31 and the negative electrode 32 . After the power supply supplies power to the positive electrode 31 and the negative electrode 32, an electric field can be applied on the wound surface, thereby stimulating wound healing and accelerating the healing speed of the wound surface.

[0028] The first film layer 1 communicates with negative pressure equipment and strong oxyge...

Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, the only difference is that in this embodiment, such as figure 2 As shown, the positive electrode 31 of the electric field device 3 is arranged in the annular area covered by the first closed ring 11 and the second closed ring 12, and the first closed ring 11 and the second closed ring 12 can be made of flexible materials such as rubber. This setting structure is equivalent to setting up a blockage inside the positive electrode 31 to avoid direct conduction between the positive electrode 31 and the negative electrode 32 through seepage due to excessive seepage, and ensure that the electric field of the positive electrode 31 and the negative electrode 32 can be applied to the wound.

Abstract

The invention discloses a dressing for negative pressure electric field coupling strong oxygen therapy, which comprises a first film layer covering a wound surface and a wound edge, and the first film layer is communicated with negative pressure equipment and strong oxygen equipment; the edge of the first film layer is provided with a flexible first closed ring which is folded towards the center of the first film layer, the suspended edge of the first closed ring is attached to the wound edge under high pressure, and a closed area is defined by the suspended edge of the first closed ring, the wound surface and the first film layer; the electric field device comprises a positive electrode arranged at the wound edge, a negative electrode arranged at the center of the wound surface and a power supply for supplying power to the positive electrode and the negative electrode. The dressing for negative pressure electric field coupling strong oxygen treatment has the advantages that the structure is simple, negative pressure, an electric field and strong oxygen are reasonably combined, and the treatment time is shortened.

Description

technical field [0001] The invention relates to the technical field of dressing structures, in particular to a dressing for negative pressure electric field coupling strong oxygen therapy. Background technique [0002] Negative pressure dressing is a common dressing for wound treatment. Its main function is to extract the interstitial fluid produced by the wound, and to provide the wound with a closed environment isolated from the outside world to prevent infection by foreign bacteria and make the wound better and more clean. Fast healing. Clinical medicine shows that oxygen has a good promoting effect on wound healing, and damaged tissue will accelerate the healing speed under the action of oxygen. The stimulation of the electric field also has a rapid healing effect on the wound. However, when negative pressure and strong oxygen are combined, there will be air pressure conflicts. Under negative pressure, the dressing will stick to the wound surface, but under high pressu...
