TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a medical micro power negative pressure dressing. BACKGROUND

[0002] People often cause skin trauma due to external force in sports, work and daily life, and with the change of human disease spectrum, skin ulceration wound caused by increasing metabolic diseases also increases day by day, in addition, the smooth repair of postoperative wound also causes the close attention of medical workers. For the skin wound after debridement, the wound itself, the most important two problems of successful repair are whether the inflammatory exudate or purulent secretion of the wound can be smoothly drained, and whether the drug acting on the wound can really play a role.

[0003] At present, the medical dressing used in the medical field is usually made of some cotton materials, which is a protective wound medical material with water absorption, and some have medicinal ingredients on the inner layer of the dressing. The clean wound with little exudation after operation suture can isolate the invasion of external bacteria and play a protective role.

[0004] The existing medical micro power negative pressure dressing is not suitable for chronic wounds with obvious exudation when in use, and for wounds with obvious exudation, the use is easy to cause the aggregation of wound inflammatory exudate, which is not conducive to the growth of wound. UTILITY MODEL CONTENT

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a medical micro power negative pressure dressing, comprising an upper skin film layer, the bottom of the upper skin film layer is provided with a liquid storage layer, the bottom of the liquid storage layer is provided with a lower skin film layer, the surfaces of the upper skin film layer and the lower skin film layer are provided with mesh holes, the medical micro power negative pressure dressing has a three-layer structure, the middle liquid storage layer has a "reservoir type water storage" function, and the upper and lower skin film layers have special "exudate management" performance.

[0007] Preferably, the upper skin film layer and the lower skin film layer can be a treatment surface dressing, and any one of the skin film layers can be used for dressing.

[0008] Preferably, the diameter of the mesh is 1-3 μm, by setting the mesh, not only water molecules can pass through, but also bacteria, fungi and viruses and other microorganisms in the wound can pass through under the action of the micro-dynamic negative pressure formed, thereby creating a clean micro-environment for the wound. The non-woven fabric with soft material is non-toxic and non-irritating, and can be directly applied to the wound.

[0009] Preferably, the epithelial membrane layer and the lower epithelial membrane layer are both polyvinyl alcohol foam wound protection materials, which have good hydrophilic, liquid absorption and permeability. The material can actively drain, and by covering with a medical transparent film, a relatively closed environment can be formed to generate negative pressure suction effect.

[0010] Preferably, the material of the liquid storage layer is medical pure sponge. The partial vacuum of the sponge body produces negative pressure suction effect on the wound and the deep soft tissue, achieves the effect of absorbing the whole wound exudate into the dressing, and no exudate is left on the wound, and the wound tissue gradually subsides and promotes local blood circulation.

[0011] Preferably, the liquid absorption capacity of the liquid storage layer is ten times the volume, so that the exudate is locked in the liquid storage layer, the skin membrane layer is wet but has low liquid content, the good environment for wound healing is maintained, and the growth of epithelial cell granulation tissue is promoted, thereby achieving the effects of non-sticking and painless dressing change.

[0012] In summary, the present application mainly has the following beneficial effects:

[0013] The wound is covered by the skin membrane layer, and then a medical transparent film is completely attached and sealed. In this way, a relatively closed environment is formed on the wound. When the novel material absorbs the wound exudate and gradually expands, the film is gradually lifted, the closed space becomes larger and larger, a partial vacuum is formed, the partial vacuum of the sponge body produces negative pressure suction effect on the wound and the deep soft tissue, achieves the effect of absorbing the whole wound exudate into the dressing, and no exudate is left on the wound, and the wound tissue gradually subsides and promotes local blood circulation.

[0014] The present application locks the exudate in the liquid storage layer, the skin membrane layer is wet but has low liquid content, the good environment for wound healing is maintained, and the growth of epithelial cell granulation tissue is promoted, thereby achieving the effects of non-sticking and painless dressing change, absorbing the whole viscous exudate, skipping the residual exudate and scabbing period, and making the wound heal quickly and reducing or eliminating the scar.
