Title:
SELF-DRIVEN MEDICINE INJECTION DEVICE AND INJECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/099472
Kind Code:
A1
Abstract:
A self-driven medicine injection device, comprising: rubbing a friction nanogenerator and an electrochemical liquid medicine pump, wherein the friction nanogenerator is used for generating electric energy under the action of mechanical energy to provide power source to the electrochemical liquid medicine pump; and the electrochemical liquid medicine pump is used for producing the electrochemical reaction and generating gas to rise the air pressure to drive liquid medicine in the electrochemical liquid medicine pump to flow out to be injected into the part requiring therapy. By means of an implantable electrochemical liquid medicine pump, the time of administration and the medicine measurement can be autonomously controlled so as to get rid of dependence of batteries, prolong the service life of such instruments, and eliminate risk of implantable batteries to human bodies.
