Medical bandages are the most common medical products in orthopedics. There are plaster bandages, polyester bandages and glass fibers in the market according to the manufacturing materials, the following is an introduction and comparison of medical bandages made of these materials.
Plaster bandage
Plaster was first used in orthopedic dressing, but due to its low strength, it was clinically found that plaster was applied to cotton tape to make bandage. The strength of using this bandage was higher than that of pure plaster, but the strength was still limited, and many layers need to be used. The patient is very large After fixed dressing. When it is hot, use plaster or plaster cotton bandage, which is very prone to allergy or infection. At the same time, it is especially watertight, which seriously affects the daily life of patients and is not convenient for doctors to check. During the examination, plaster dressing body must be opened.
Polyester bandage
The polyester bandage developed from gypsum bandage has good adhesion, toughness, solvent resistance, non-toxicity and good compatibility with human body, but it is a thermal material, it must be softened before use. This kind of bandage must also be soaked in about 80 hot water. The water temperature is relatively troublesome, and it is very easy to cause skin scald or softening and ineffective during operation.
Glass fiber polymer bandages
High strength, non-toxic, no harm to human health, not afraid of water and humidity, can be cured in five minutes to play a fixed role, good air permeability, patients do not have to remove the bandage when taking X-ray films for follow-up examination, the non-supporting part bandage fixed only needs 2/3 layers, and the supporting part bandage fixed only needs 4 or 5 layers, which is 5 times lighter than cotton plaster bandage.
