Abstract

A medicine vial holder and interchangeable syringe guides are disclosed, the object being to assist in the home administration of shots, especially for individuals with poor eyesight or hand control. The interchangeable syringe guides may be of varying lengths and have apertures through them of varying diameters to accommodate syringes of varying sizes. One group of embodiments comprises a means for holding the medicine vial while allowing the interchangeable syringe guide to be changed to fit the syringe to be filled. Once the medicine vial and syringe guide are in place the syringe is guided to the vial via the guide and filled. Another group of embodiments incorporates several syringe guides into one object and, depending on what size syringe is to be filled, the position of this object with respect to the vial is changed to select the appropriate sized guide. Means for magnifying the view of the vial and syringe and means for retaining the vial and syringe are present in some embodiments as well.
