Description

Automatic injection system

Technical Field

The utility model relates to the field of automation, in particular to an automatic injection system.

Background

The vaccine is an automatic immune preparation for preventing infectious diseases, which is prepared by artificially attenuating, inactivating or utilizing transgenosis methods for pathogenic microorganisms (such as bacteria, rickettsia, viruses and the like) and metabolites thereof. The vaccine retains the property of pathogenic bacteria to stimulate the immune system of an animal. When an animal body contacts the pathogen without harm, the immune system can generate certain protective substances, such as immune hormone, active physiological substances, special antibodies and the like; when the animal is exposed to the pathogenic bacteria again, the immune system of the animal will follow its original memory and produce more protective substances to prevent the pathogenic bacteria from harming.

The birth and development of the vaccine greatly protect the health of human beings, and the conventional vaccination of large-scale population is not gradually popularized until 20 th century, and is increasingly widely known and accepted by the public.

By vaccination, people have already eliminated smallpox, and poliomyelitis cases have been reduced by 99%, infectious diseases such as diphtheria are rare, and the incidence of diseases such as measles and neonatal tetanus is remarkably reduced. The effect of vaccines on human health is not excessive, and the birth of each new vaccine is a great victory for human beings to overcome an infectious disease! To date, no medical treatment has been able to have such an important, lasting and profound effect on human health as a vaccine; nor is any therapeutic available to eliminate a disease from the earth at the very least cost of a vaccine.

In order to achieve mass vaccination of large populations at a population care event, automatic injection devices have been developed to automatically inject vaccines in batches. Since the current injector is generally provided with a needle, to realize automatic injection, a driving mechanism is necessary to realize that: the first step is inserted the syringe needle in human muscle, and the second step propelling movement syringe's piston realizes the propelling movement of medicament, and the third step: the action of pulling out the needle head is not realized by a proper mechanism at present.
