ABSTRACT:
My invention is a syringe which does not require the use of prior art plunger mechanisms to function (and its method of use). My syringe generally comprises the main body section and fluid transmission means, usually a needle, of prior art syringes. A seal slidingly disposed within the main body section prohibits fluid flow through the main body section. Although this seal corresponds to the plunger seal used in prior art syringes, my syringe does not include a plunger rod which is an essential part of prior art syringes. In the preferred embodiment, a second body section is attached to the main body section at the main body section end opposite the fluid transmission means. Fluid communication is provided between main body section and second body section. The end of second body section opposite the attachment to main body section must be open and must be sized to allow the insertion of a person's finger therein so that the finger may substantially cover the opening. With this syringe, a medical provider may insert his finger into second body section through the opening so that his finger substantially covers the opening. By rubbing the inner surface of second body section, the medical provider can cause the seal to slide within the main body section and the syringe to inject or suction fluid, depending on the direction of the rubbing motion. In the preferred embodiment, second body section is selectively removably attached to main body section so that second body section may be re-used multiple times with different main body sections.
