Dose guides for injection syringe

Abstract

The present embodiments provide for simple devices that guide the loading and dispensing of accurate small doses of fluid from standard injection syringes.

1 - 22 . (canceled) 
     
     
         23 . A dose-loading guide for loading an injection syringe, the dose-loading guide comprising:
 a grip portion; and   a collar portion connected to the grip portion;   wherein the collar portion is rigid along its height, the collar portion defines an opening that removably receives a dose-delivery guide during dose loading of an injection syringe, and the collar portion is configured to stop movement of an extended syringe plunger rod into an injection syringe barrel at a predetermined distance defined between the proximal end of the injection syringe barrel and the distal end of the plunger rod; wherein the dose-delivery guide has a height, the difference between the collar portion height and the dose-delivery guide height corresponds to a volume of fluid to be delivered by the syringe, and, if the syringe barrel comprises a depression in which the dose-delivery guide will sit, the difference corrects for the depression; and   wherein the grip portion facilitates positioning of the collar portion around the dose-delivery guide and along the plunger rod during dose loading, and the grip portion facilitates removal of the dose-loading guide after dose loading is complete.   
     
     
         24 . The removable dose-loading guide of  claim 23 , further comprising an indication of a dose volume to be retained by the injection syringe after use of the dose-loading guide. 
     
     
         25 . The dose-loading guide of  claim 23 , wherein the collar portion is integral to the grip portion.
