Description

Enclosed dressing for skin exudates

Technical Field

The present utility model relates to an occlusive dressing for skin exudates.

Background

Negative pressure wound therapy, also known as vacuum assisted wound closure, refers to the continuous or intermittent application of sub-atmospheric pressure to a wound surface by a wound dressing system to promote wound healing, the wound dressing system comprising a negative pressure wound therapy apparatus comprising a fluid collection system and a dressing, the dressing covering a wound site, and a negative pressure source connected to the dressing by the fluid collection system, the negative pressure source providing negative pressure to the wound, and wound exudate entering the fluid collection system for collection.

The existing wound dressing system is difficult to meet the requirement of high exudates (more than 10 milliliters exuded in 24 hours) in clinic, and the problem that the dressing is easy to suck up liquid and needs to be replaced frequently is often fed back, so that the wound dressing system is difficult to be applied clinically. At present, the treatment of the medium and high exudates is clinically aimed at, a sponge, a PU film and a suction/flushing pipeline are adopted, a doctor cuts the sponge according to the shape of a wound, the characteristic that the sponge can accommodate more exudates is utilized, the replacement frequency can be reduced to a certain extent, one side of the sponge is integrally stuck with the PU film, holes are needed to be punched in the PU film after sticking is finished, a sucking disc is stuck again, then the sucking disc is connected to a negative pressure wound therapeutic apparatus for negative pressure wound therapy, the operation procedure is complex, and the risk of air leakage is easier to generate; the sponge pores are predicted to be easy to be blocked by more viscous exudates under the negative pressure condition, so that the replacement frequency is higher; the sponge has poor moisturizing performance, is easy to dry and is not easy to return to soft after being dried, and still needs to be replaced, so that the replacement frequency is high; the sponge is in direct contact with the wound, and secondary damage is easily caused to the wound when the dressing is taken down.

Therefore, there is a need for a dressing for medium and high exudates that reduces the frequency of replacement.

Disclosure of Invention

The object of the present utility model is to provide a closed dressing for skin exudates. The utility model is used for absorbing medium and high exudates and has lower replacement frequency.

The technical scheme of the utility model is as follows: the utility model provides a closed dressing about skin exudates, including the ventilated membrane that blocks water, the top of ventilated membrane that blocks water is equipped with the bleeder vent, bleeder vent department is equipped with the sucking disc, is equipped with the pipe on the sucking disc, and the bottom of ventilated membrane that blocks water is equipped with lock water layer, support layer, silica gel layer and from the type membrane in proper order, is equipped with a plurality of air vents on the silica gel layer, from the type membrane outer fringe with block water the outer fringe annular connection of ventilated membrane and form the cavity from between type membrane and the ventilated membrane that blocks water, lock water layer, support layer and silica gel layer all are located the cavity.

In the aforementioned occlusive dressing for skin exudates, the catheter is provided with a Robert clip.

In the aforementioned closed dressing for skin exudates, the catheter is provided with a luer connector, which is located between the Robert clip and the water-blocking breathable film.

In the aforementioned closed dressing for skin exudates, the water-blocking breathable film is made of a PU film, the water-blocking layer is made of a sponge plate, and the support layer is made of sandwich cloth.

The aforementioned dressing for skin exudates further comprises a fitting, wherein the fitting comprises a medical sponge and an edge sealing strip.

In the aforementioned closed dressing for skin exudates, the fitment further comprises a cross negative pressure drainage tube and a tee.

In the aforementioned occlusive dressing for skin exudates, the fitment further comprises a drainage canister and a source of negative pressure.

Compared with the prior art, the dressing can be prefabricated in a factory, and when the dressing is used, the dressing is only required to be covered at a wound after the release film at the bottom is torn off and fixed by the edge sealing strip, so that the operation procedure is simple, and the air leakage risk is reduced. The sponge board in the dressing can hold more exudates, can reduce the change frequency of dressing, and when the sponge board took place the knot, the accessible luer was connected and is injected a small amount of normal saline in to the dressing, makes the sponge board soft back, does not need to change, further reduction dressing's change frequency. When the normal saline is injected, the pressure connection between the negative pressure source and the dressing is cut off through the Robert clamp, so that the normal saline is ensured to flow to the dressing side. The dressing is contacted with the wound through the gel layer, and the wound is not easy to be damaged secondarily when the dressing is replaced due to the fact that the material characteristic of the silica gel layer is that the silica gel layer is not easy to adhere to the wound. Through setting up sandwich cloth between silica gel layer and sponge board, utilize the great hole of sandwich cloth, reduce the flow resistance of effusion, comparatively viscous effusion can be absorbed in the sandwich cloth, can not produce the phenomenon of standing (under negative pressure state, atmospheric pressure can form pressure to the dressing, under the condition that does not sandwich cloth, after the expansion of water-locking layer absorbs water, can lead to comparatively viscous effusion can't flow to water-locking layer and other positions, lead to the wound to appear standing the phenomenon), also reduce the quantity in the effusion enters into the sponge board simultaneously, prevent the sponge board jam, reduce the change frequency of dressing equally. In summary, the utility model is used for absorbing medium-high exudates with low replacement frequency.
