Drug delivery micropump device

Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a drug delivery micropump device which comprises a packaging shell, a driving module, a first driving electrode and a second driving electrode, and the driving module, the first driving electrode and the second driving electrode are installed in the packaging shell; a liquid medicine inlet and a liquid medicine outlet are formed in the two opposite ends of the packaging shell respectively, a plurality of microcavities penetrating through the two side faces of the driving module are formed in the driving module, the liquid medicine inlet is communicated with the liquid medicine outlet through the microcavities, and the first driving electrode and the second driving electrode are arranged on the two side faces of the driving module respectively. The invention provides a drug delivery micropump device based on the basis of the electro-osmosis micro-driving principle, the structure is simple and compact, only two core assemblies including the driving electrode and the driving module are arranged in the device, no mechanical motion friction part is arranged, the pump body can be assembled and integrated in a micro mode in a drug delivery system, the size can be obviously reduced, and the problem that a mechanical pump is prone to faults due to mechanical movement is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and specifically discloses a drug delivery micropump device. Background technique [0002] Drug delivery pump is an indispensable key medical device for clinical infusion treatment of diseases. It is widely used in the precise delivery of micro-volume analgesics, insulin, antihypertensive drugs, and cancer chemotherapy drugs. Such drugs are expensive, and they can be delivered through drug pumps to achieve targeted and precise therapeutic effects, which can maximize the efficiency of drug use, reduce drug costs, and significantly reduce drug side effects. [0003] In clinical applications, mechanical pumps such as gear rotor pumps, screw pumps, turbo pumps, peristaltic pumps, etc. have always been the mainstream pumps for drug delivery, whether in vitro or in vivo. Because the mechanical pump pumps the drug through mechanical movement, it will cause power dissipation loss due to heat gen...

AI Technical Summary

Problems solved by technology

Because the mechanical pump pumps the drug through mechanical movement, it will cause power dissipation loss due to heat generated by mechanical friction, and it is also easy to cause mechanical failure; on the other hand, the mechanical moving parts of the mechanical pump are not conducive to the miniaturization of the drug delivery system And integration, often lead to the volume of the infusion system is too large, but also prone to friction noise
