Chemotherapy drug treatment cylinder for clinical test

The invention relates to the related technical field of medicine treatment equipment, in particular to a clinical test chemotherapy medicine treatment barrel which comprises a barrel body and further comprises a needle head separating mechanism, a crushing mechanism and a collecting mechanism which are arranged in the barrel body. A needle head separating mechanism is arranged in a cylinder body, after a needle head clamping assembly clamps a needle head and a needle tube clamping assembly clamps a needle tube, a sliding pin is driven to slide from the end, close to the needle tube clamping assembly, of a lifting guide groove to the end, away from the needle tube clamping assembly, of the lifting guide groove by adjusting the angle of a separating driving shaft under the action of a rocker, and the needle head is separated from the needle tube clamping assembly. Therefore, the needle head can be pulled out from the needle tube, and the needle head can be separated from the needle tube. The problem that in the
