Abstract
Syringe attachments and syringes have particular suitability to the precision dispensing of small amounts of high viscosity materials, such as dermal fillers. Syringes and attachments may include precision position indicators viewed from multiple positions to enable a user to determine plunger position and the amount of dispensed contents with precision. A configuration of the attachment may be slidably secured to a syringe to permit a user to operate the syringe from a lateral position using sliding movement of the thumb and fingers of one hand, for example. This configuration may be particularly suitable for self-administered insulin injections.
