Abstract

The invention discloses a dynamically controllable micro-dose accurate liquid medicine delivery system and method. The system comprises a micro-fluidic pump, a liquid inlet chamber, a control module,a detection module and a display module connected in sequence. The liquid inlet chamber can be connected with the micro-fluidic pump, and a cavity of the micro-fluidic pump can serve as the liquid inlet chamber. Liquid medicine is injected into a specific liquid inlet chamber, the micro-fluidic pump is driven to have a micro displacement change by a single-chip and other control modules, and the liquid medicine is pushed to output. Meanwhile, the actual output flow velocity and the metabolite variation after liquid medicine addition are determined by utilizing the detection module, fed back tothe control module, judged by a processor and subjected to dynamic regulation, so that the micro-dose liquid medicine can be accurately output according to requirements, and accurate regulation and output of the liquid medicine can be really realized. The expected output flow velocity and the actual output flow velocity of the liquid medicine can be displayed on the display module. According to the system and method disclosed by the invention, the change of the metabolite after medicine application can be dynamically fed back to a medicine application end, the therapeutic scheme is regulatedin real time, and the liquid medicine delivery amount is accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dynamically controllable micro-dosage liquid medicine delivery system and method based on a micro-flow pump. Background technique [0002] In the fields of biomedical research such as medical testing, new drug development, and genetic engineering, the precise delivery of trace amounts of liquid medicine is a very important topic. According to a survey, 54% of inpatient complaints about nursing work are related to infusion. In medical research, in the process of in vitro cell culture, how to quantitatively and real-time input the liquid medicine into the culture medium without affecting the metabolic response of the cells is, in the final analysis, a problem of precise delivery of the liquid medicine. In addition, with the rise of precision medicine, in order to improve drug efficacy, the delivery of fixed-point targeted drugs also puts forward requirements for the prec...
