Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a splash-proof chemotherapy drug dispenser. Background Art

[0002] Chemotherapy drugs are drugs used to treat tumors. Chemotherapy drugs can kill tumor cells. These drugs can act on different stages of tumor cell growth and reproduction, inhibiting or killing tumor cells. Chemotherapy drug treatment is currently one of the main means of treating tumors;

[0003] During chemotherapy, doctors need to mix multiple drugs into a special medicine for treating tumors. During the mixing process, doctors usually need to operate multiple medicine bottles. When too many types of liquid medicine need to be added, there is a problem that some liquid medicine may be missed or the medicine bottle may be accidentally knocked over during the preparation process.
