Medical Supplies: Syringes, gloves, tubing, and equipment often rely on plastic for hygiene
Plastic is the backbone of modern medical supplies, ensuring hygiene and safety in ways that were unimaginable a century ago. Consider the syringe: a device so ubiquitous that it’s easy to overlook its complexity. Made primarily from polypropylene or polystyrene, syringes are designed for single use to prevent cross-contamination. For instance, a 1 mL insulin syringe delivers precise doses (typically 10–100 units per injection) to diabetics, relying on plastic’s ability to maintain sterility and accuracy. Without plastic, such precision would be costly and risky, as glass or metal alternatives would require rigorous sterilization between uses.
Gloves are another critical example of plastic’s role in medical hygiene. Latex, nitrile, and vinyl gloves act as a barrier against pathogens, protecting both healthcare workers and patients. Nitrile gloves, made from synthetic rubber, are particularly popular due to their durability and resistance to punctures.
