In-vitro alternating magnetic field driven bladder urination pump

Abstract

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.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a bladder urination pump driven by an external alternating magnetic field, in particular to an external alternating magnetic field driven bladder urination pump for assisting urination of patients with neurogenic bladder dysfunction. The invention belongs to the transformation technology of a bladder urination pump driven by an external alternating magnetic field. Background technique [0002] Neurogenic bladder dysfunction is a common disease of the urinary system. It is often caused by spinal cord trauma, congenital dysplasia, and central nervous system lesions. It is also called neurogenic bladder. There are often clinical symptoms such as urinary incontinence, dysuria, and urinary retention. It can also lead to complications such as urinary tract infection and urinary tract stones. In severe cases, it can lead to hydronephrosis and even renal failure, which is life-...
