மருத்துவ கையுறைகளுக்கான மூலப்பொருட்கள் என்ன?

1. Latex

Material Source & Composition: Latex is a commonly used material for medical gloves, primarily made from natural latex derived from the sap of rubber trees. Its main component is polyisoprene, along with small amounts of proteins, sugars, lipids, and ash. The molecular chain structure of natural latex provides excellent elasticity and flexibility.

Features & Applications:

Latex gloves offer superior elasticity, conforming closely to the hand without causing tightness. They allow for precise movements, making them ideal for surgical procedures (e.g., suturing blood vessels or nerves), medical examinations, and dental treatments. However, some individuals may develop latex allergies (itching, redness, or rashes) due to the proteins in natural latex.

2. Nitrile

Material Source & Composition: Nitrile gloves are made from nitrile rubber, a copolymer synthesized from butadiene and acrylonitrile. The carbon-carbon double bonds in its molecular structure provide high puncture resistance and elasticity.

Features & Applications:

Nitrile gloves exhibit exceptional chemical resistance (e.g., oils, acids, and alkalis), outperforming latex in chemical protection. They are latex-free, making them suitable for users with latex allergies. Widely used in surgical rooms, laboratories, and medical inspections, they are also preferred for tasks requiring oil or chemical exposure.

3. Polyvinyl Chloride

Material Source & Composition: PVC gloves consist of PVC paste resin, plasticizers, heat stabilizers, viscosity reducers, colorants, and fillers. Plasticizers enhance flexibility, while stabilizers prevent thermal degradation.

Features & Applications:

PVC gloves are cost-effective and resistant to weak acids, alkalis, and water penetration. However, they have poor elasticity and breathability. Commonly used in basic medical procedures (e.g., injections, wound dressing) and low-risk environments where budget constraints exist.
