First of all, let's understand VSD (what is VSD), the role of VSD dressing in VSD negative pressure therapy. Earlier we also explained the negative pressure source, today we will take a look at the relevant information of VSD dressing for VSD negative pressure treatment.

First of all, the VSD dressing develops the negative pressure from point drainage and strip drainage to the entire surface for drainage, which is mainly to make the drainage more adequate and the treatment effect of VSD more significant.

THE VSD dressing mainly consists of a medical sponge and a drainage tube buried inside the sponge:

Medical sponges, now the most clinically used for PVA material dressing, but all PVA material medical sponges have the disadvantage of drying and hardening. Because it has been very skilled in use, all the mainstream products are still dominated by PVA material, and its therapeutic effect is also very good.

Another material is PU material dressing, at present, only two companies in the world have this type of products, namely the United States KCI and Shandong Chuangkang Biological. In the United States, KCI is mainly based on small-area suction cups, and there is no arranged pipe in the sponge. The PU dressings of Chuangkang Bio (www.medilogy.cn) are also of various sizes and sizes, and there are different specifications of cloth tubes in the sponge to make the drainage more adequate. Compared with foreign products, the price of domestic products is also a major advantage.

Intracabular drainage tube, there are two kinds of drainage tubes used by various manufacturers in the CURRENT clinical use of VSD dressings, most of which are low cost and will wound patients by compressive PVC tubes; There is also a kind of drainage tube for the silicone drainage tube used by Chuangkang Bio, which costs several times that of PVC tube, but has good flexibility and does not compress the patient's wound.
