Abstract
An automatic injecting apparatus has a housing formed with a recess having an annular rim and provided with a hypodermic-holding case in which a hypodermic syringe can be held, with the needle tip of the syringe projecting into the recess and lying just inward of the rim thereof. The housing is formed with a suction chamber having a piston and connected via a passage to the recess. A spring urges this piston away from the passage so as normally to aspirate air from the recess and, when the rim is snugly engaged against the skin of a person to be injected, to pull the skin of a person to be injected into piercing contact with the needle tip. Similarly a spring-loaded mechanism is provided for pushing the plunger down. Neither the spring-operated mechanism for the syringe plunger nor the piston can be displaced, however, until detecting means provided around the rim ascertains that the rim is firmly seated against the skin of the person to be injected. Only then can the device automatically function to perform a hypodermic injection.
