Negative Pressure Wound Therapy medical sponge is a wound dressing for clinical use.
First, let's explain the term Negative Pressure Wound Therapy medical sponge separately.
Negative Pressure Wound Therapy: this is a form of pure physical therapy that relies on negative pressure suction. Negative Pressure Wound Therapy is used for many conditions.
Medical Sponge: here refers to the professional high specification medical sponge. At present, PVA and PU materials are widely used.

We also learned earlier about what a Negative Pressure Wound Therapy Medical Sponge is.Now let's talk to you about two materials of Negative Pressure Wound Therapy Medical Sponge (PVA and PU).
First, let's talk about PVA medical sponge dressings.The dressings made of this material are mostly used at present, and the negative pressure drainage technique is used in the early stage to replace the dressing of oil gauze.The color of PVA dressings is white, the three-dimensional space structure is good, most of them are straight tube products, the closure is slightly complicated mainly reflected in the closure of the drainage tube; If the PVA dressing is used for a long time or closed badly, it will become dry and hard, which is the past problem faced by the current dressings of this material.
 
Let's talk about the new PU medical sponge dressing (polyurethane), the dressing is a new dressing, itself is dry and soft, will not be dry and hard; PU medical sponge dressings have better biocompatibility than PVA medical sponge dressings and more uniform three-dimensional space.At present, PU medical sponge dressings are mainly used in the treatment of chronic wounds that are difficult to heal, such as bedsores and furfural, and the effect is better than PVA medical sponge dressings in the treatment of chronic wounds.
