Abstract
The invention relates to an electromagnetically driven left-right reciprocating liquid pumping mechanism. An iron core is driven to move by the principle of electromagnetic coupling functions to compress or extend a hollow threaded tube cavity, so that a whole pump body is driven to alternately shrink and stretch. Liquid flow is promoted by volume shrinkage, and the hollow threaded tube cavity is prepared from elastic soft medical polymer materials with good fatigue resistance and biocompatibility, so that injury to biological cells can be prevented to a great extend. A structure is more compact by the aid of magnetic driving. The distance between the iron core and a permanent magnet is adjusted by rotation of a connecting adjustment rod, the motion displacement of the iron core can be changed to control each liquid pumping volume of the pump body. Since rigid squeezing force is not applied to liquid in the whole liquid pumping process, or the liquid flows at a high speed, damage to the liquid is reduced to a very low extent. When the mechanism is applied to extracorporeal circulation, generated pulse blood pressure can improve peripheral circulation and improve oxygen supply for the brain.
