IMPROVED INJECTABLE DELIVERY SYSTEM

An improved integral flow-through injectate delivery system (10) comprises fluid flow means (24) having a proximal and a distal end. The proximal end comprises a first port having fluid inlet means (44) for connecting the flow means (24) to a source of fluid injectate (28) and a second port (46) adapted to be connected to a syringe means (18). The distal end of the fluid flow means (24) is adapted to be connected to a fluid delivery means (30) for delivering the injectate to the patient and the syringe means (18) is adapted to direct injectate fluid from the injectate source (28) through the fluid inlet (44) and the fluid flow means (24) to the fluid delivery means (30). A first check valve (34) is in fluid-flow communication with the fluid inlet means (44) and the fluid flow means (24) and a second check valve means (36) is in fluid-flow means with the fluid flow means (24) and the fluid delivery means (30). A sensing means (22) is disposed within the fluid flow means (24) at its distal end for sensing a characteristic of fluid flowing therethrough, usually temperature. A fluid flow regulating 17 means (72) is placed within the fluid flow means (24) between the fluid inlet means (44) and the sensing means (22) to delay or limit injectate from flowing therethrough except when being directed by the syringe means (18).
