Magnetic-medicine targeting gathering method and magnet structure

Abstract

The invention discloses a magnetic-medicine targeting gathering method. The magnetic-medicine targeting gathering method includes the following steps that the position of a focus of the body is determined; a magnet structure is made, and a gathering point which is not coincided with the magnet structure is identified; the focus is coincided with the gathering point; according to the magnetic fieldcharacteristics of the magnet structure, magnetic medicine is applied to the body, and the magnetic medicine is gathered at the focus position. After the magnetic medicine enters the body, as the magnetic field effect generated by the magnet structure is joined to the gathering point step by step, namely, the magnetic field effect generated by the magnet structure gradually reaches the position of the focus, and the medicine effect is developed at the position of the focus. As the gathering point is not coincided with the magnet structure, namely, the gathering point is separated from the magnet structure, the magnet structure is arranged outside the body and can generate the gathering point located inside the body, and when the focus is located inside the body, namely, a certain distanceexists between the focus and the body surface, the magnetic medicine can be still gathered to the position of the focus in the manner that the focus is coincided with the gathering point to achieve the aim that the magnetic medicine is gathered to the deep part in the body.

Description

technical field [0001] The invention relates to the field of magnetic drug delivery, in particular to a magnetic drug targeted aggregation method and device. Background technique [0002] For the drug targeting of diseases, especially tumor treatment, the current main technical means include active targeting, passive targeting, physical targeting and other approaches. Among them, both active and passive targeting achieve drug aggregation in vivo to achieve targeting through certain rules (such as specific recognition of molecules, deposition in menstrual blood circulation, etc.). These technologies can achieve a certain degree of drug aggregation, but they all have some problems, such as: targeting accuracy, drug concentration levels need to be improved and so on. Physical targeting technology uses external physical environment such as temperature or magnetic field to transport drugs to the lesion site. This type of technology can achieve better drug concentration at an ap...
