A hypodermic syringe for use in situations wherein an experienced medical person may not be available to administer an injection. The device is sterile and water-tight and may be carried about on one's person without special precautions being taken. Upon use, substantially instantaneous but sequentially controlled skin penetration and injection are achieved. The syringe can be used only once, and has a shelf life of more than one year with most medicaments.
