The original design of the mobile checkup cart is to facilitate the medical staff to quickly and accurately obtain patient information during the checkup process, and to improve work efficiency. Since sharps bins (e.g., medical round sharps boxes) are mainly used to collect and dispose of medical waste, especially dangerous items such as needles and razor blades, placing sharps bins on mobile room-check carts is not in line with their designed use and health and safety codes. In addition, the sharps container is usually large and has a certain weight, if placed on the mobile check-up vehicle, it will increase the load of the vehicle and the difficulty of movement, and even affect the stability of the vehicle, posing a safety hazard to health care workers.
