During production, in order to save memory space and convenient transportation, the size of usual foam 2 is: thickness is from 1mm to 10cm, and width is from 1mm to 2m；Length is 1mm to 100m.When depositing and transport, by foam rolled, when needing, cut out as required from a beginning.
Covering the PU film 1 with breathability on described foam 2 end face outwardly, foam covers internal layer release paper 3 and outer layer release paper 4 towards the end face of wound.
The side folded outwards of internal layer release paper forms flap 31, internal layer release paper 3 is covered on the foam end face away from PU film by flap mode outwardly, makes flap not contact with foam.Internal layer release paper only covers the foam of a part, then outer layer release paper covers the most exposed part of foam, and, make outer layer release paper cover the flap in internal layer release paper.
As shown in Figure 4 and Figure 5, the position of described PU film correspondence foam coats latticed adhesive tape, arranging air-vent 11 on PU film between adhesive tape, the part coating medical glue outside PU film is positioned at latticed adhesive tape, an end face of foam is pasted onto on PU film by the network-like adhesive tape on PU film.When foam has adsorbed the discharge of wound, these discharges just outwards can be volatilized by the air-vent 11 on PU film such that it is able to keeps good breathability.
The aperture of described air-vent 11 is between 0.1 to 0.4 micron.The individuality of general antibacterial is more than 0.4 micron, therefore, major part antibacterial cannot enter foam through air-vent 11 and pollute wound, dust in air is mostly more than 0.4 micron, foam can not be entered, thus PU mould can help to filter out most dust and antibacterial, the health helping to maintain foam is clean.And the aperture of air-vent is more than 0.1 micron, it becomes possible to have preferable breathability.
Owing to foam is the softest, cover and extruding will be caused to cause pain wound on wound.Particularly to ulcer wound and large-area burn wound, soft foam covers will not be expressed to wound on wound, moreover it is possible to further functions as the effects such as anti-inflammatory analgetic, thus contributes to reducing wound pain and auxiliary treatment.
During use, first open outer layer release paper 4, then pinch flap 31 and open internal layer release paper 3, by exposed for foam out, foam is covered on wound, due on foam with multiple liquid drain hole, PU film has good breathability, so that wound can be through liquid drain hole and PU film and extraneous exchange of air, the discharge enabling wound passes through liquid drain hole to extravasation, and outwards can volatilize through liquid drain hole, help to maintain wound and be dried, it is to avoid the discharge of wound accumulates in and causes below foam infecting further.
In actual application, the size of foam is sheared according to the size of wound.Foam end face covers upper internal layer release paper 3 and outer layer release paper 4, and another contrary end face covers the PU film with breathability, then by foam rolled, in order to deposit and transport.When needing to use, foam is sheared by the size of wound, the generally area of foam is greater than wound area, it is possible to all covered by wound under foam, after having sheared foam, outer layer release paper and internal layer release paper are opened from foam and takes away, then foam is covered on wound, make wound be fully located at the lower section of foam, then the adhesive plaster one end with medical adhesive is pasted on the PU film on foam, the other end is attached on the skin that is positioned at outside foam, is fixed by foam.
In actual application, in order to easy to use, can also be only at the PU film that an end face covering of a foam is equivalently-sized with foam, other end does not cover internal layer release paper and outer layer release paper, directly press PU film mode rolled outwardly to preserve, during use, size on demand is cut out the size needed, cover on wound by PU film mode outwardly, then the adhesive plaster one end with medical adhesive is pasted on the PU film on foam, the other end is attached on the skin that is positioned at outside foam, is fixed by foam.
For the relatively-stationary situation of wound shape and size, such as some surgical wound, the foam that shape and size are fixing can also be produced, at this moment, the area of PU film is generally equal to internal layer release paper and the projected area of outer layer release paper, the projected area of internal layer release paper and outer layer release paper is more than the area of foam, and PU film extends around out from foam.During use, just foam can be fixed on wound by the PU film extending around out from foam, it is not necessary to use adhesive plaster again.
As shown in Figure 6, owing to wound is typically middle part more seriously, the lightest the closer to the part traumatic condition at edge, therefore, the thickness of foam gradually successively decreases to edge from center, makes the ratio of foam actual generation effect significantly promote, and contributes to reducing cost.
Thickness in the middle part of foam is more than 1mm to 8mm, has stronger adsorptivity, it is possible to a large amount of discharges absorbing wound spilling, helps to maintain being dried of wound.
