Description

Needleless injection oriented medicine taking reminding method and system based on data fusion

Technical Field

The application relates to a needleless injection technology, in particular to a method and a system for reminding a patient to take medicine for needleless injection based on data fusion.

Background

Needleless injection is also called as "gentle injection", and when medicine is injected, liquid medicine permeates skin at a high speed and diffuses into body tissues in a mode of superfine, high-speed and straight-line ejection of high-pressure jet flow by using instant high pressure generated by a pressure source without using a needle, and is gradually applied to clinic as a medical technology and a new injection technology.

For patients needing to inject hormones such as insulin or growth hormone, the injection frequency is high, the treatment time is long, when the needle-free injection is used, because the depth of the injected drugs entering a human body is limited, the injury to subcutaneous tissues is extremely small, and nerve endings are stimulated little, compared with the needle injection, the needle-free injection has no obvious pricking feeling, and the problems of fear, pain, needle breakage and the like caused by long-term injection are overcome easily, so that the compliance is greatly improved; in addition, the onset time when using needleless injection is fast at least 15 minutes compared with having the needle, to the injection of insulin, can save the dosage, can make the effect of medicine more steady simultaneously, reduce the risk of diabetic complication, and to the injection of auxin, have the periodic observation statistical result to show, have the needle to inject and increase 1.7 centimetres in a month, needleless injection increases 2.4 centimetres in a month, has shown the advantage of needleless injection in the aspect of macromolecule medicine injection. It is expected that needleless injection will become the mainstream of drug injection in the future with the continuous and deep research on medicine.

Most of the existing medicine-taking reminding related products realize the reminding function based on alarm clock setting, are complex to operate, lack of humanization and low in intelligentization level, have high possibility of wrong reminding and missed reminding due to unreasonable alarm clock reminding set by human factors, and particularly for old people with high medicine-taking frequency, the alarm clock reminding logic relation required to be set is complex, and the possibility of the wrong reminding and the missed reminding is greatly increased; in addition, special products for needle-free injection medication reminders are more rare in the market.
