In medical settings such as hospitals, health centers, and clinics, noise issues are easily overlooked, but they directly affect the quality of patient rest and the work experience of medical staff. The abnormal noise generated by the rolling wheels of hospital beds, nursing carts, instrument transfer carts, and rescue equipment moving back and forth in the ward can interfere with patients’ sleep and exacerbate the emotional anxiety of postoperative and elderly patients. Silent medical wheels have become an indispensable basic accessory in the upgrading and transformation of modern medical institutions.
Many people mistakenly believe that casters are just simple wheels, and the source of noise is only the friction of the wheel surface against the ground. In fact, there are multiple reasons for the noise generated by medical wheels: the wheel body material is too hard and makes a thumping sound when it collides with the ground; The workmanship of the bearings is rough, and there is abnormal noise from internal friction during rolling; The bracket rotates and freezes, causing metal friction and screaming when turning; The impurities inside the wheels are worn out, and the noise continues to increase after long-term use. Ordinary industrial casters can be directly applied to medical equipment without any visible problems in a short period of time. Repeated pushing and pulling during transportation will result in continuous exposure to noise and are not suitable for hospital ward environments.
