HYG TC-I型热化学消融系统对碱金属消融剂的精确控制
Precise Injection Control of Alkali Metal Ablation Agents by HYG TC-I Type Thermo Chemical Ablation System
摘要
Abstract
This article was intended to carry out the study and discussion with regard to the problems as well as solutions in the process of using HYG TC-I type thermo chemical ablation system for the precise injection control of the alkali metal ablation agents. Until now, the general standard of precision injection pumps has not been clearly defined, and the flow accuracy of most such products are in the range of 5%~20%. However, the alkali metal ablation dosage is microliter grade, such a large error will lead to a less accurate control in ablation reaction. Via the optimized design of the storage scheme and the drive structure, the accurate intensity and extent of alkali metal ablation can be achieved in order to ensure the safety and effectiveness of the thermo chemical ablation therapy. Through the theoretic calculation and measurement, the injection accuracy of thermochemical ablation system for HYG TC-I type can be controlled within 2%. Therefore, the precise control of the alkali metal ablation agents can be realized, which provides the basic conditions for the realization of alkali metal ablation therapy.关键词
