Unit dose dry powder ejection carpule

Abstract

A simple, disposable device for a wounded individual to dispense a antibiotic or other medicine directly into their own open wound or treatment of a wound by a second party. The device dispenses a preloaded quantity of dry medication from an opening that is covered by a removable cap. Removal of the cap followed by pressing of a plunger dispenses the medication. The design of the carpule, barrel, of the device, the preloaded powder medicament, the flexible rod and rod head that pushes the dry powder into the wound and material selection appropriate to use in unfavorable environments are other features of the device.
