The invention provides an in-vitro alternating magnetic field driven bladder urination pump. The pump comprises a magnetic rotor, a pump body, an impeller, a ceramic bearing, a spindle, a return spring and an alternating magnetic field generator, wherein the alternating magnetic field generator is arranged on the anterior abdominal wall of a human body; the pump body is arranged in the bladder; a urine suction port a and a urine drainage port b are formed on the pump body; the magnetic rotor and the impeller are arranged in the hollow cavity of the pump body; the magnetic rotor is sleeved at one end of the spindle, and the impeller is sleeved at the other end of the spindle; the spindle is supported against the pump body; the return spring is sleeved on the spindle between the impeller and the magnetic rotor; and a hub of the impeller and the urine drainage port b of the pump body form a urethra switching valve. When the alternating magnetic field generator is electrified, the impeller rotates, the urine is sucked from the suction port a, the urethra switching valve is opened, and the urine is drained from the drainage port b; and after urine is drained, the alternating magnetic field generator is disconnected, and the bladder recovers a urine storage state. The bladder urination pump without infection, damage, urine leakage or back flow has the advantages of simple structure, safety in use and convenience in operation.
