The design I.V. Express provides a low-cost but possible way to reduce greatest burden of nurses. This systemic design consists of two main parts. One is the plastic liquid bottle with a redesigned bottom which contains a new connecting structure. The other is the lid for the powder bottle, which could be easily broken by the forenamed structure.
When a nurse need to prepare I.V. drippings, he/she can just put the two parts together, then the liquid could flew to the powder bottle and dissolve the powder. By such a system, the prepare procedure is reduced greatly from 5 steps to only 1.
