IMPROVED INJECTATE DELIVERY SYSTEM

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