Is medical dressing a material?

Medical dressing stickers medical applicator medical dressing is a material? In fact, is a material products. Medical dressings are divided into the following.

    Natural gauze: (cotton pad) This is the use of the earliest and most extensive class of dressings.

advantage:

  1, strong and rapid absorption of wound wound exudate

  2, the production process is relatively simple Disadvantages: 1, permeability is too high, easy to make the wound dehydration 2, adhesive wounds, replacement will cause re-mechanical damage

  3, the external environment of microorganisms easy to pass, cross the chance of infection higher

  4, the amount of more frequent replacement, time-consuming, and the suffering of patients due to the reduction of natural resources, gauze costs are gradually increasing, therefore, in order to avoid excessive use of natural resources, the emergence of the application of polymer materials (synthetic fiber) processed into medical dressings , This is the synthetic fiber dressing.

Synthetic fiber dressings: This kind of dressing has the same advantages of gauze, such as economy, and has a good absorption performance, etc., and some products also have self-adhesive, so that it is very convenient to use. However, such products also have the same shortcomings of gauze, such as high permeability, the external environment, particulate matter without blocking and so on.

Multi-Membrane Dressings: This is a more advanced dressing, with oxygen, water vapor and other gases can be free and transparent, and the environment of particulate foreign matter such as dust and microbes can not pass the characteristics.

advantage:

  1, blocking the environment microbial invasion of the wound, to prevent cross-infection

  2, there is moisture, so that the wound moist, will not stick the wound, which will not produce the replacement of mechanical mechanical injury

  3, self-adhesive, easy to use, and transparent, easy to observe the wound situation

Disadvantages:

  1, poor ability to absorb exudate

  2, the cost is relatively high

  3, the wound around the skin dipping opportunities, so this type of dressing is mainly used in postoperative and exudation of small wounds, or as an adjunct to other dressings dressings.

Foam Polymeric Dressings This is a kind of dressing made from foamed polymer (PU), which usually covers a layer of poly-semi-permeable membrane, and some also has self-adhesive properties.

Key Benefits:

  1, fast and powerful exudate absorption capacity

  2, low permeability, so that the wound to keep moist, to avoid replacement dressings occur again mechanical damage

  3, the surface of the semipermeable membrane barrier properties, to prevent environmental particulate matter such as dust and microbial invasion, to prevent cross-infection

  4, easy to use, good adaptability, can be suitable for all parts of the body

  5, thermal insulation, buffer the external momentum

Disadvantages:

  1, due to too strong absorption performance, for low exudation of the wound may affect their own debridement process

  2, the cost is relatively high

  3, due to opaque, inconvenient to observe the wound
