Abstract: A high volume carpule system for storing and dispensing a high volume of anesthetic to a patient. A preferred embodiment of the high volume carpule system generally includes a syringe having a modified carpule cavity comprised of an upper ring member and a lower ring member which are linked together by a first side member and a second side member. The side members are oriented in such a manner as to allow a pair of slots through which side portions of a high capacity carpule may extend. A high capacity carpule comprised of a substantially cylindrical shape with an elongated cross-section is disclosed for use with the modified carpule cavity. In an alternate embodiment, a second high capacity carpule design is disclosed for use with conventional, prior art syringes. By using the present invention, a dentist or surgeon may administer a higher volume of anesthetic without having to switch carpules within a syringe.
