| ABSTRACT Objective: To solve the problem of low success rate of placing nasointestinal tube rapidly at the bed, this paper proposes a design of nasointestinal tube based on magnetic drive technology. Methods: The dynamic factors in the process of placing the nasointestinal tube were analyzed, and the design scheme of driving the induction magnet in the body forward by rotating the magnetic field outside the body was proposed, in order to shorten the floating time of the nasointestinal tube. Results: The design consists of two parts: magnetic nasointestinal tube and external magnetic drive device. The magnetic nasointestinal tube is composed of a tube body and an induction head, which includes a magnet core and a silicone shell. The magnetic driving device is composed of multi-pole magnets and hand-held micro-motor. During operation, a large rotating magnetic field is generated by the external magnetic drive device to drive the induction head of the nasointestinal tube to do axial rotation, which can accelerate the movement of the nasointestinal tube in the intestinal tract and shorten the floating tube time. Conclusion: The design is based on the principle of magnetic drive technology, which is ingenious, in accordance with the principle of magnetism, simple to operate and has the potential of clinical application. |
