Medical sponges can also be regarded as a relatively large category of
sponges. Of course, there are not many primary production materials for medical
sponges. Common categories are PU and PVA. Let’s briefly understand the
advantages and disadvantages of these two materials!
PU
PU medical sponge has obvious advantages in biocompatibility, non-toxic, no effect, good air and water permeability, soft and elastic, and not easy to block. It was the most widely used medical sponge in European and American countries at that time.
Medical PU Foam
PU sponge has different types of wounds with hydrophilicity, hydrophobicity, and different densities. When there are more secretions on the wound surface, the hydrophobic function will discharge the secretions faster and with lower resistance; when the wound surface becomes monotonous, the hydrophilic function can effectively maintain moisture. Keep the wound surface moist, which is beneficial to the rapid growth of granulation arrangements.
Use low-density sponge when there are more pus and blood secretions and necrosis on the wound, which is beneficial to the secretion of secretions, and it is not easy to block sponges and ducts. When the granulation arrangement grows, using a high-density sponge can effectively prevent the granulation arrangement from adhering to the sponge.
PVA
PVA sponge also has many benefits. Generally, the air foaming technology is a skill that rare companies in the world can grasp.
Green, environmentally friendly, non-toxic and harmless, water-permeable and air-permeable, highly functional three-dimensional structure and ultra-fine structure, and different from the PVA medical sponge produced by other companies, it has better elasticity, softness, comfort, and better Anti-blocking and anti-blocking properties.
There is a common problem with PVA sponges because of their shortcomings-monotonous hardening, which is not conducive to the use of wounds with few secretions and monotonous wounds. If the wound has begun to grow granulation arrangements, slow wounds are not suitable.
