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.
