Medical polymer bandages are divided into glass fiber polymer bandages and polyester fiber polymer bandages, which are respectively made of glass fiber or polyester fiber coated polyurethane compounds. This new product has been widely popularized in many countries and has only been introduced to the market in our country in recent years. As more and more medical institutions choose polymer bandages, the products on the market are becoming increasingly diverse. At this time, how to distinguish the advantages and disadvantages of medical polymer bandages and choose products with good quality and good price. So here's how to distinguish the advantages and disadvantages of medical polymer bandages:
Is there any burr on the cutting edge: Soak the medical polymer bandage that has just been unpacked in water for two seconds, squeeze it out two to three times, take it out of the water, use scissors to cut the medical polymer bandage, and gently grab the newly cut section with your hand. Poor quality bandages will grab some burrs, and KNIT products will have no burrs. The burrs on low-quality bandages can cause pain or puncture the patient's skin, while high-quality products from Cognac have very neat and smooth edges that do not produce burrs and therefore do not harm the patient's skin.
Is the weight consistent? Randomly take five bandages from the batch of products and weigh them on a scale. The difference between the top and bottom of the KNET product will not be one to two grams, and the difference between the poor products will be five grams or even more than ten grams. Inconsistent weight indicates uneven application of adhesive, which affects the bonding effect of the bandage.
Is the width uniform: Take the bandage out of the packaging tape and measure the width of the bandage in sections with a ruler. Poor quality products have varying widths, while KNET products have consistent widths due to the use of high-quality imported fabrics. Inconsistent width indicates insufficient toughness of the base fabric of the bandage, which is produced during the bandage application process and can affect the strength of the bandage during use.
Whether the bandage adhesion is firm: Poor bandages have insufficient viscosity of polyurethane compounds, and the multi-layer bandage adhesion is not very firm. It will loosen and fall off on its own before the time for the affected limb to heal and the bandage to be removed, thereby affecting the recovery of the injured person.
Is it convenient for doctors to operate: Poor bandages are often difficult to operate due to the preparation of polyurethane adhesive, and doctors often stick their latex gloves when wearing them. The KNET bandage adopts the most advanced polyurethane adhesive preparation process, making it very convenient for doctors to wrap the bandage, especially during shaping operations, as the bandage does not stick to gloves.
Does the product have a pungent odor: Poor bandage products also emit a pungent odor due to the presence of a raw material with an unpleasant odor in the polyurethane adhesive formula, which is used to coat and manufacture bandages and splints. Replaced the odorous raw materials to prevent the unpleasant odor from dissipating.
Whether the quality is stable and long-lasting: Poor quality plywood products such as polyurethane glue are prone to leakage from the outer non-woven fabric, causing partial hardening of the plywood and affecting the shaping effect, causing discomfort to patients.
The above points are to teach everyone how to distinguish the advantages and disadvantages of medical polymer bandages.
