Abstract: A single-use cover assembly that obscures a substantial majority or an entirety of an injection needle from view before, during, and after an injection procedure. The cover assembly includes a housing and a needle sleeve that retracts and extends by sliding axially within the housing. The needle sleeve carries a locking collar that moves from a first position to a second position once the needle sleeve is fully retracted. In the first position the locking collar allows retraction of the needle sleeve from a fully extended position. In the second position, a portion of the locking collar covers a tip of the needle, thereby preventing retraction of the needle sleeve from the fully extended position.

Abstract: A treatment method that increases circulation and pluripotency of stem and progenitor cells within a patient can be used to fight off or cure various diseases for the patient such as chronic kidney disease or end-stage renal disease. An administrator of the treatment method is provided with a medicinal-administration system such as an intravenous injection system.
