After purchasing a wheelchair, it's essential to stay informed about maintenance and necessary adjustments. Regular servicing can extend the lifespan of the wheelchair and ensure safety and functionality. Users should also be mindful of accessories that can enhance their experience, such as cushions for added comfort, storage options, and assistive devices to aid in mobility.

在选择合适的助行器时，用户需要考虑几个因素。首先是高度的调节，用户应确保助行器的高度适合自己的身高，以保持良好的姿势。其次，轮子的大小和类型同样重要，较大的轮子更适合不平坦的路面，而小轮子则在室内使用时更加灵活。此外，助行器的材质和重量也是用户需要考虑的因素，轻便的助行器更便于携带和使用。

When considering the purchase of hospital bed wheels, healthcare facilities must evaluate their needs carefully. Institutions with high patient turnover, such as emergency rooms, may benefit from investing in higher-quality wheels that can withstand frequent use without wear and tear. Additionally, wheels with larger diameters and superior bearings are often easier to maneuver, which can significantly reduce strain on healthcare workers during busy shifts.
