Description

Low temperature plasma dressing

The present invention relates to a surgical dressing, in particular to a low-temperature plasma dressing.

The treatment and healing of severe or large wounds usually takes a long time. Studies have found that cryogenic plasma has a considerable therapeutic effect on promoting wound healing. By using cryogenic plasma equipment to treat wounds, the biofilm that hinders wound recovery can be removed, thereby accelerating wound healing.

The low-temperature plasma equipment generally includes a plasma drive device and a plasma head electrically connected to the plasma drive device. Currently, medical personnel hold the plasma head and move it relative to the patient's wound, so that the low-temperature plasma generated by the plasma head gradually treats various parts of the wound. However, this method of moving the handheld plasma head relative to the patient's wound requires not only the operation of medical personnel, but also the manpower consumption. The treatment range of the plasma generated by the plasma head is small, and the plasma head must be constantly moved relative to the wound, which is quite inconvenient.

Therefore, the object of the present invention is to provide a low-temperature plasma dressing that can improve at least one disadvantage of the prior art.

Therefore, the novel low-temperature plasma dressing is suitable for being arranged on the skin surface and can be driven by a plasma driving device to generate low-temperature plasma. The low-temperature plasma dressing comprises an insulating layer, an electrode module arranged at the bottom of the insulating layer, and a dielectric module and a conductive gel layer arranged at the bottom of the electrode module.

The electrode module includes a first electrode and a second electrode which are spaced apart and arranged at the bottom side of the insulating layer and are used to electrically connect the plasma driving device. The dielectric module is arranged at the bottom side of the first electrode and has a contact bottom surface facing the skin. The contact bottom surface has a plurality of slot spaces for the first electrode to generate the low-temperature plasma. The conductive glue layer is electrically connected and arranged at the bottom side of the second electrode and is used to contact the skin.

Therefore, the novel low-temperature plasma dressing is suitable for being arranged on the skin surface and can be driven by a plasma driving device to generate low-temperature plasma. The low-temperature plasma dressing comprises an insulating layer, an electrode module arranged on the bottom side of the insulating layer, and a conductive gel layer arranged on the bottom side of the electrode module.

The electrode module includes a first electrode and a second electrode which are spaced apart and arranged at the bottom side of the insulating layer and are used to electrically connect the plasma driving device. The first electrode includes a first electrode portion which extends and is distributed in a staggered manner in the longitudinal and transverse directions, and the first electrode portion defines a plurality of pores which can be used to generate low-temperature plasma. The first electrode portion has a metal core and a coating body of a dielectric material which is coated outside the metal core. The conductive glue layer is electrically connected and arranged at the bottom side of the second electrode and is used to contact the skin.

The efficacy of the present invention is that through the structural design of the low-temperature plasma dressing, it can be directly laid on the skin surface and can be driven to generate the low-temperature plasma to treat the wound, thereby improving the shortcomings of the existing low-temperature plasma treatment device that requires manual operation and cannot treat large wounds at the same time.

Before the present invention is described in detail, it should be noted that similar components are represented by the same number in the following description. In addition, the size of the layered structure in each figure of the present invention is only for illustration and is not limited to the scale of the figure when implementing.

Referring to Figures 1 and 2, a first embodiment of the novel low-temperature plasma dressing 200 is suitable for being applied on the skin surface and can be electrically connected to a plasma driving device (not shown) and can be driven by the plasma driving device to generate low-temperature plasma for treating the skin.

The low-temperature plasma dressing 200 includes a flexible and deformable insulating layer 3, an electrode module 4 disposed on the insulating layer 3, and a dielectric module 5 and a conductive glue layer 6 disposed on the bottom side of the electrode module 4.

The insulating layer 3 is made of an electrically insulating material, such as but not limited to a plastic film and a fiber cloth.

The electrode module 4 includes a first electrode 41 and a second electrode 42 disposed at intervals on the insulating layer 3. The first electrode 41 and the second electrode 42 can be deformed along with the bending of the insulating layer 3. The first electrode 41 has a sheet-shaped first electrode portion 411 disposed on the bottom side of the insulating layer 3, and a first power connection portion 412 exposed on the top side of the insulating layer 3 and electrically connected to the first electrode portion 411. The second electrode 42 has a second electrode portion 421 in the shape of a ring disposed on the bottom side of the insulating layer 3 and spaced around the first electrode portion 411, and a second power connection portion 422 exposed on the top side of the insulating layer 3 and electrically connected to the second electrode portion 421.

In the first embodiment, the first power connection portion 412 and the second power connection portion 422 are both electrode buckle types, which can be used for the plasma driving device to be electrically connected, but in practice, the appearance of the first power connection portion 412 and the second power connection portion 422 is not limited thereto. In the first embodiment, the first electrode portion 411 and the second electrode portion 421 are both high-conductivity metals, such as but not limited to copper, silver, gold, etc.

The dielectric module 5 includes a dielectric layer 51 disposed on the bottom side of the insulating layer 3 and the first electrode portion 411 and covering the dielectric material of the first electrode portion 411. The dielectric layer 51 separates the first electrode portion 411 from the second electrode portion 421. The dielectric layer 51 has a contact bottom surface 511 facing the skin, and the contact bottom surface 511 is recessed with a plurality of slot spaces 512 that can be used for the first electrode 41 to generate the low-temperature plasma.

In practice, the slot spaces 512 may be distributed in an array, and the cross-sectional shape of each slot space 512 may be, for example but not limited to, a circle, or a polygon such as a quadrilateral or an octagon, and the concave shape may be, for example but not limited to, a cone, a truncated cone, etc. In addition, the opening ratio of the slot spaces 512 relative to the contact bottom surface 511 ranges from 60% to 90%, that is, the ratio of the total opening area of the slot spaces 512 to the area of the contact bottom surface 511 ranges from 60% to 90%.

In the first embodiment, the material of the dielectric layer 51 is, for example but not limited to, silicone and polytetrafluoroethylene (PTFE).

In the first embodiment, the thickness range of the first electrode portion 411 and the second electrode portion 421, and the thickness range of the dielectric layer 51 are all between 0.05 and 2.00 mm.

The conductive gel layer 6 is electrically connected to the bottom surface of the second electrode portion 421 and covers the second electrode portion 421. The conductive gel layer 6 is, for example but not limited to, a hydrogel containing a conductive medium. Since there are many types of medical conductive gels commonly used in the market, and it is not the focus of the present invention, it will not be described in detail, and is not limited to the above aspects.

When the low-temperature plasma dressing 200 of the first embodiment is used, the low-temperature plasma dressing 200 is applied to the skin surface, so that the conductive adhesive layer 6 is roughly attached to the normal skin area outside the wound range, and the dielectric layer 51 covers the wound. Then, the plasma driving device applies a voltage of a predetermined frequency to the first electrode 41 and the second electrode 42, driving the first electrode portion 411 to generate the low-temperature plasma in the slot spaces 512 of the dielectric layer 51, and then the low-temperature plasma can be used to treat the wound area covered by the dielectric layer 51.

Referring to FIG. 3 , a second embodiment of the novel low-temperature plasma dressing 200 is different from the first embodiment in that the structure of the dielectric module 5 is different. For the sake of convenience, only the differences between the embodiments will be described below.

In the second embodiment, the dielectric module 5 includes a dielectric layer 51 disposed on the bottom side of the first electrode portion 411 and the insulating layer 3 to cover the first electrode portion 411, and a porous gauze layer 52 stacked on the bottom side of the dielectric layer 51. The gauze layer 52 has a contact bottom surface 521 facing the skin, and the contact bottom surface 521 is formed with a plurality of slot spaces 522.

When the low-temperature plasma dressing 200 of the second embodiment is used, the wound is covered with the gauze layer 52. When the plasma driving device applies a predetermined frequency voltage to the first electrode 41 and the second electrode 42, the first electrode 41 is driven to generate the low-temperature plasma in the slot spaces 522 of the gauze layer 52, and the wound can also be treated with the low-temperature plasma.

4 and 5 , a third embodiment of the novel low-temperature plasma dressing 200 differs from the first embodiment in terms of overall layered structure design.

In the third embodiment, the low-temperature plasma dressing 200 includes the insulating layer 3, an electrode module 4 disposed on the bottom side of the insulating layer 3, and the conductive glue layer 6 disposed on the electrode module 4. The electrode module 4 includes a porous mesh first electrode 41 and a second electrode 42 disposed on the insulating layer 3 at intervals.

The first electrode 41 includes a first electrode portion 411 in a strip shape and extending in a staggered manner vertically and horizontally and arranged on the bottom side of the insulating layer 3, and a first power connection portion 412 exposed on the top side of the insulating layer 3 and electrically connected to the first electrode portion 411. The first electrode portion 411 is wound around itself to form a porous mesh structure 413, and surrounds and defines a plurality of pores 414 that can be used to generate the low-temperature plasma. The first electrode portion 411 has a metal core 415 and a dielectric material coating 416 that coats the metal core 415. The material of the metal core 415 is the same as that of the first electrode portion 411 in the above two embodiments. The material of the cladding body 416 is the same as that of the dielectric layer 51 in the above two embodiments.

The second electrode 42 includes the second electrode portion 421 of the mesh structure 413 which is spaced around the first electrode portion 411, and the second electrical connection portion 422 which is exposed on the top side of the insulating layer 3 and electrically connected to the second electrode portion 421. The conductive adhesive layer 6 is electrically connected to the bottom side of the second electrode portion 421.

When the low-temperature plasma dressing 200 of the third embodiment is used, the mesh structure 413 formed by the first electrode portion 411 is covered on the wound, and then the plasma driving device applies a predetermined frequency voltage to the first electrode 41 and the second electrode 42 to drive the first electrode portion 411 to generate the low-temperature plasma in the pores 414 defined by it.

During implementation, a piece of gauze may be laid on the wound first, and then the first electrode portion 411 of the low-temperature plasma dressing 200 may be overlapped on the gauze. The low-temperature plasma dressing 200 may also be driven to generate the low-temperature plasma in the pores between the first electrode portion 411 and the gauze to treat the wound.

It should be particularly noted that in the above embodiments, the second electrode portion 421 is designed to be ring-shaped, but the implementation is not limited to this.

In summary, the structural design of the low-temperature plasma dressing 200 can be directly laid on the skin surface, and the plasma driving device can drive the low-temperature plasma to treat the wound. In addition, the plasma driving device can drive multiple low-temperature plasma dressings 200 at the same time to treat multiple wounds at the same time, which can improve the shortcomings of the existing low-temperature plasma treatment device that requires manual operation and cannot treat large wounds at the same time. Therefore, the new low-temperature plasma dressing 200 is indeed a very innovative creation and can indeed achieve the purpose of this new invention.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
