Embodiment Construction

[0031] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] The invention provides a self-driven medicine injection device including a friction nanogenerator and an electrochemical medicine liquid pump. Among them, the friction nanogenerator generates electric energy under the action of external mechanical energy, provides power for the electrochemical pump in the electrochemical liquid pump, and generates electrochemical reactions (such as water electrolysis) in the electrochemical liquid pump to increase the air pressure and drive The medicinal liquid in the electrochemical medicinal liquid pump flows out and is injected at the site to be treated.

[0033] For the treatment of eye diseases as an example, see f...

Abstract

The invention discloses a self-driven medicinal liquid injection device, comprising: a frictional nanogenerator and an electrochemical medicinal liquid pump, wherein the frictional nanogenerator is used to generate electrical energy under the action of mechanical The liquid pump provides power; the electrochemical liquid pump is used to generate electrochemical reaction and generate gas to increase the air pressure, drive the liquid in the electrochemical liquid pump to flow out, and inject it at the site to be treated. The use of implantable electrochemical liquid medicine pumps can independently control the time and metering of drug administration, and get rid of the dependence on batteries, increase the service life of such instruments, and eliminate the risk of implanted batteries entering the human body.

Description

technical field [0001] The invention relates to a drug injection device, in particular to a drug injection device and an injection method which convert human body motion, vibration, friction, etc. into electric energy. Background technique [0002] Drug injection is currently the most common means of disease treatment. The traditional method uses needles and syringes to inject medicinal liquid into the lesion, but frequent use of traditional syringes will cause damage to human tissues. Especially in the treatment of eye-related diseases, because the eyeball tissue is difficult to heal the trauma caused by frequent injections, many patients have to choose external eye drops for treatment. Most eye drops cannot reach the lesion because they cannot pass through the physiological barrier of the eyeball. Therefore, eye drops for external use require patients to use frequent and large amounts of medicines, which increases the operational difficulty of treatment. [0003] Using t...
