Abstract
The infusion pump for stem cells includes a liquor storage device and an infusion pipe. The inner wall of the liquor storage sac of the liquor storage device and inner walls of the infusion pipe are provided with an anionic protective film to prevent stem cells from adhering to the infusion pump by mutual repulsion between anions. The infusion method includes checking an infusion pump for integrity, losing a liquor stop clamp, injecting a mixed liquor of stem cells and medicine, covering a protective cap, opening the liquor stop clamp, closing the liquor stop clamp for use, connecting an external cone joint with a venous cannula, and then opening the liquor stop clamp. The method also includes steadily placing the liquor storage sac on a horizontal plane using an auxiliary placing device, and after infusion ends, closing the liquor stop clamp, and disconnecting the external cone joint.
