Abstract: Disclosed are a negative-pressure drug loading apparatus and a negative-pressure drug loading method. When the apparatus is in use, drug particles to be loaded are placed into the particle storage tube, and a proper amount of drug solution is introduced. The particle storage tube is placed in the body, and the sealing space is sealed. A vacuum pump is used to execute a negative pressure operation in the body until the inside of the particle storage tube is pumped into a vacuum. An air valve of the vacuum pump is opened, such that the drug solution comes into the said particles under the action of pressure. After the pressure is stable, the particle storage tube is let stand for a period of time such that the drug solution stably stays in the said particles.
