The blood collection needle I propose has realized the simplest structure and the safest way of blood collection for donors, the operators and the waste disposers. As an example, the old type of blood collection needle had been discarded without cap. The new type of needle, however, is always caped when it is not used to the donor. This structure of the new needle can realize new process of discarding wastes, and prevent the accidents such as the operator’s reuse of the needle instead of a new one. The other problems have been also made clear after the observation and interview acted in the three blood centers and four blood donation centers.
