Abstract
The invention relates to a novel electronic pen syringe, and belongs to the technical field of drug injection. The electronic pen syringe comprises an injection component, an injection driving component and a control component. A front shell is arranged between the injection component and the injection driving component. The injection component mainly includes a medicine cartridge in which a medicine bottle can be placed. The injection driving component mainly includes a bracket, a motor, a driving screw and a push rod. The control component mainly includes a circuit board and a battery. The circuit board is fixed in a clamping groove at the upper part of the bracket, and the battery is fixed in a clamping groove at the lower part of the bracket. The motor is fixed on the rear end of the bracket. The driving screw and the push rod are placed in a cavity of the bracket. The bracket can be put into a casing along a clamping groove of the inner wall of the casing. A buckle is arranged atthe rear end of the front shell for being fastened on the casing. The bracket and components on the bracket are fixed in the casing. The electronic pen syringe has the characteristics of high injection accuracy, safety and reliability, simple structure, small size, convenient carrying and mass production.
Description
technical field [0001] The invention relates to the technical field of drug injection, in particular to a novel electronic pen-type injector. Background technique [0002] Pen injector injects drugs subcutaneously or intramuscularly for the treatment of diabetes, growth retardation, cardiovascular disease, tumor, infertility, obesity, Parkinson's, multiple sclerosis, osteoporosis, anemia, rheumatoid arthritis and other diseases, Injectable drugs include insulin, glucagon-like peptide-1 (GLP-1), growth hormone, vaccines, interferon, etc., and can also be used for drug injection in the field of medical beauty. [0003] There are two types of syringes used for injecting drugs. The conventional one is a mechanical syringe, which mainly relies on manual push to achieve drug injection. This type of syringe has a simple structure, is easy to carry, is easy to operate, has low cost, and has a high penetration rate and a large number of users; The disadvantage is that the injection ...
