fig. 2 is a cross-sectional view of an embodiment of the present invention.

The meaning of the reference symbols in the figures:

c10 upper ear reinforcing area, C20 lower ear reinforcing area, C30 dressing body, 10 buffer foam layer, 20 film layer and 30 adhesive layer.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, a foam dressing for preventing ear pressure sores comprises: the dressing body C30, an upper ear reinforcing area C10 which extends to the upper end of the dressing body C30 and is adhered to the upper edge of the ear, and a lower ear reinforcing area C20 which extends to the lower end of the dressing body C30 and is adhered to the lower edge of the ear; the foam dressing comprises the following components: a cushioning foam layer 10, a film layer 20 connected to the cushioning foam layer 10, and an adhesive layer 30 connected to the cushioning foam layer 10.

Because the back of the ear is not a smooth surface, higher requirements are put forward to the application and the fixed of product, in product design, upper ear reinforcing area C10 and lower ear reinforcing area C20 have been increased respectively, when this foam dressing is pasted and is applied on the ear, upper ear reinforcing area C10 just pastes the upper edge at the ear, lower ear reinforcing area C20 just pastes the edge under the ear, can be inseparabler like this and the laminating of ear, cooperate together with pasting layer 30, make prevent that the ear from pressing sore foam dressing is after long-time use, can also keep fine effect of pasting.

As shown in figure 1, the height of the foam dressing ranges from 40 mm to 80mm, and preferably, the height A40 of the foam dressing is 65 mm; the width is in the range of 15 to 35mm, and preferably, the width B50 is 28 mm.

The thickness range of the buffer foam layer 10 is 1-6.5 mm, and the thickness range of the thin film layer 20 is 10-50 mu m; preferably, the thickness of the cushion foam layer 10 is 2.5mm and the thickness of the film layer 20 is 30 μm.

Because the foam dressing is only used for pressure release and does not need to absorb exudates, the buffering foam layer 10 is of a three-dimensional porous large-aperture structure, the foam aperture range is 200-800 μm, and preferably, the foam aperture is 350 μm. Such pore sizes provide the cushioning foam layer 10 with better resilience and pressure relief capabilities.

Materials that may be selected for the cushioning foam layer 10 include: PVA and polyurethane, preferably, the cushioning foam layer 10 is a polyurethane foam layer, and the polyurethane foam has high resilience and good biocompatibility.

Materials that may be selected for film layer 20 include: preferably, the film layer 20 is a polyurethane layer, which has the characteristics of high air permeability and low frictional resistance, and the design of frosting the surface and low frictional resistance reduces the risk of pressure sores caused by friction of the ear band.

The adhesive layer 30 may be selected from the group consisting of: preferably, the adhesive layer 30 is a flexible silicone adhesive, which has a soft adhesive peeling property and good biocompatibility. The adhesive has the characteristics of softer adhesion, no pulling on skin during peeling, and increased air permeability due to the adoption of a dot or strip gluing mode, so that the adhesive is more comfortable to use.

The reason for the ear pressure sores mainly comprises two aspects, namely, the compression of the ear straps of the mask on the skin of the ears on one hand, and the friction of the ear straps on the skin of the ears in the using process on the other hand; the utility model designs the cellular structure of the buffer foam layer 10 into a three-dimensional porous large aperture structure (200-800 μm), so that the buffer foam layer 10 has better resilience and pressure release capacity; through having adopted the polyurethane film with thin layer 20, reduced the friction, the surface adopts dull polish low resistance design to reduce the risk that the friction of ear area produced and presses the sore.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
