Medical electromagnetic valve with magnetic fluid

Abstract

The invention discloses a medical electromagnetic valve with magnetic fluid, which comprises an emergency manual push rod, an electromagnetic valve compaction cap, an electromagnetic valve casing, an excitation coil, an electromagnetic stem, a magnetic fluid seal, nanometer magnetic fluid, a floating piston, a return spring, a photoelectric counting rod, cooling magnetic fluid, an electromagnetic shield coating, a vacuum antifriction layer and a supply cord. The medical electromagnetic valve with the magnetic fluid is mounted on a plasma separator and used for controlling separation and delivery of plasma, and can also be independently used for controlling opening and closing of a clinical infusion tube. The medical electromagnetic valve overcomes shortcomings that a traditional electromagnetic valve used in an existing plasma machine is high in resource consumption, opening and closing noise is loud, electromagnetic interference to control of a computer is caused, noise influences to patients are also caused, technical content of a structure is low, maintenance and repair are difficult and the like. In addition, the nanometer magnetic fluid replaces pure electrical iron, the medical electromagnetic valve is lighter than the traditional medical electromagnetic valve by 50%, and the medical electromagnetic valve is free of service risks, small in occupied space, convenient in organization of production, extremely low in resource consumption and free of pollution and noise, and belongs to environment-friendly medical equipment.

Description

technical field [0001] The invention belongs to the field of green medical equipment and is used for the control of the plasma transport channel of a medical plasma separator and the channel control of a medical infusion tube, that is, a magnetic fluid medical solenoid valve. Background technique [0002] The iron core of the traditional medical solenoid valve and the metal frame of the money ring rigidly attract and collide with each other, which is easy to cause self-excited oscillation of the valve core, impact noise when switching, and fluctuations in plasma delivery volume, which will cause certain sound stimulation and mental disturbance to the patients. It consumes more electrical pure iron, has electromagnetic interference, and has defects such as affecting computers. Contents of the invention [0003] The object of the present invention is to provide a magnetic fluid medical solenoid valve equipment with multiple usage places, no electromagnetic and chemical pollu...
