Medicament delivery device and methods for delivering drugs to infants and children; (U.S. Patent 10,688,244); Eric S. Edwards of Moseley; Glen L. Kelley of Glen Allen and others; Kaleo Inc. of Richmond: A method of delivering epinephrine includes placing a distal end surface of a medical injector in contact with a target location of a patient.

The medicament container is coupled to a needle. The injector is actuated such that the energy storage member produces a force to move the needle from a first needle position to a second needle position. A distal tip of the needle extends from the distal end surface by a distance of between 7 millimeters and 8 millimeters when the needle is in the second position. A portion of the force is exerted to expel the dose of epinephrine when the needle is in the second position.
