The smart pillbox on the N+ intelligent nursing cart not only reduces the repeated operations of nurses on drugs, but also notifies nurses of drug delivery time. The drug identifier above can correctly identify drugs and ensure that medical accidents will not happen due to administration errors of nurses, which can relieve their stress and make patients feel at ease. The design of separating the sub-cart and main cart allows nurses to push the main cart alone for nursing practice when they are not delivering drugs, thus solving the problem of the nursing carts being too heavy or bulky.
