Improved injectate delivery system
First Claim
1. A fluid flow delivery system for delivering injectate fluid to a patient comprising:
- fluid flow means having a proximal and a distal end, wherein said proximal end comprises a first port having fluid inlet means for connecting said flow means to a source of fluid injectate and a second port connected to a syringe means, and said distal end comprises a port for connecting said fluid flow means to a fluid delivery means for delivering the injectate to the patient;
wherein said syringe means is in fluid-flow communication with said injectate source through said fluid inlet means and is in fluid-flow communication with said fluid flow means through said second port, and said fluid flow means is in fluid-flow communication with said fluid delivery means;
sensing means disposed within said fluid flow means at its distal end for sensing a characteristic of fluid flowing therethrough; and
fluid flow regulating means interposed between said fluid inlet means and said sensing means, for delaying said injectate from contacting said sensing means;
wherein said fluid flow means, said sensing means and said fluid flow regulating means are part of an integral fluid flow assembly.

Abstract
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.
