One embodiment includes a fluid delivery device sized to meet ANSI/AAMI ID54:1996(R) 2005 and not mate with ANSI/HIMA MD70.1 or ISO 594/1 and ISO 594/2 standards for intravenous ports and connectors to prevent accidental intravenous delivery of fluids intended for enteral delivery. The system includes at least one of a locking tab and a stop flange configured to not mate with matching connectors not configured to satisfy the enteral feeding standards and not specifically configured to mate with the fluid delivery device. ## Claims ### Claim 1 A fluid delivery system, comprising: a first fluid delivery end formed on one of a syringe or a fluid delivery device that further comprises: sizing that meets enteral feeding standards including ANSI/AAMI ID54:1996(R) 2005 and not mate with standards for intravenous ports and connectors including ANSI/HIMA MD70.1, ISO 594/1 and ISO 594/2; and at least one axially aligned locking tab; and a connector for enteral feeding for delivering fluids to a patent via a connected tube, wherein the connector further comprises: a fluid receiving end that meets enteral feeding standards including ANSI/AAMI ID54:1996(R) 2005 and not mate with standards for intravenous ports and connectors including ANSI/HIMA MD70.1, ISO 594/1 and ISO 594/2 and that further includes: at least one axially aligned channel having an axial length that is greater than a channel width for receiving the at least one axially aligned locking tab of the first fluid delivery end in an axial direction when the first fluid delivery end is inserted into the fluid receiving end of the connector; and a locking region extending perpendicularly to the channel and configured to receive the axially aligned locking tab and to hold the first fluid delivery end when the first fluid delivery end is inserted and subsequently rotated into a locking position; a second fluid delivery end that defines an internal conduit sized to limit a flow rate to a specified flow rate desired for a patient; and wherein the at least one channel and the at least one axially aligned locking tab are configured to enable the first fluid delivery end to be inserted axially to a final depth prior to the first fluid delivery end of the syringe or fluid delivery device being turned and locked into place. ### Claim 2 (depends on 1) The fluid delivery system of claim 1 wherein the first fluid delivery end further includes a stop flange configured to allow the first fluid delivery end and the fluid receiving end to engage and lock and to prevent connections with connectors that do not meet enteral feeding standards. ### Claim 3 (depends on 1) The fluid delivery system of claim 1 wherein the first fluid delivery end is a male connector end sized to meet standards for enteral feeding systems including ANSI/AAMI ID54:1996(R) 2005. ### Claim 4 (depends on 1) The fluid delivery system of claim 1 wherein the first fluid delivery end is a male connector end sized not to mate with devices made according to standards for I.V. delivery of medication including ANSI/HIMA MD70.1, ISO 594/1 and ISO 594/2 standards for intravenous ports and connectors. ### Claim 5 (depends on 1) The fluid delivery system of claim 1 wherein the first fluid delivery end further includes a plurality of stop flanges configured to allow the first fluid delivery end and the fluid receiving end to engage and lock and to prevent connections with connectors that do not meet enteral feeding standards. ### Claim 6 (depends on 1) The fluid delivery system of claim 1 wherein first fluid delivery end comprises a plurality of locking tabs. ### Claim 7 A fluid delivery system, comprising: a syringe for intravenous delivery of medication; a fluid delivery device further including a female connector end sized to receive and mate with a male end of the syringe and a male connector end extending outwardly from the female connector end, the male connector end sized to meet standards for enteral feeding including ANSI/AAMI ID54:1996(R) 2005 and not mate with standards for I.V. delivery including ANSI/HIMA MD70.1, ISO 594/1 and ISO 594/2 standards for intravenous ports and connectors; and wherein the fluid delivery device includes: a first fluid delivery end that further includes an axially aligned locking tab for insertion into a female end of a connector having an axially aligned channel having an axial length that is greater than a channel width and configured to receive the locking tab an axial direction wherein the channel of the connector and the locking tab of the fluid delivery device are configured to enable the fluid delivery end to be inserted axially to a final depth prior to being turned and locked into place and wherein the fluid delivery device is configured to only mate with specified connector ends for enteral feeding; and a second fluid delivery end that defines an internal conduit sized to limit a flow rate to a specified flow rate desired for a patient. ### Claim 8 (depends on 7) The fluid delivery system of claim 7 wherein the fluid delivery device is permanently attached to the syringe with a locking mechanism, an adhesive material, a bonding agent, or an application technique. ### Claim 9 (depends on 8) The fluid delivery system of claim 8 wherein the application technique comprises one of spin welding, pressure mounting or overmolding and applying. ### Claim 10 (depends on 8) The fluid delivery system of claim 8 wherein the delivery end of the fluid delivery device further includes at least one stop flange to allow the first fluid delivery end and the fluid receiving end to engage and lock and to prevent connections with connectors that do not meet enteral feeding standards. ### Claim 11 A syringe system, comprising: a chamber for temporarily holding a fluid for delivery enterally to a patient; a male connector end fluidly connected to the chamber for delivering the fluid to a tube; wherein the male connector end is sized to meet ANSI/AAMI ID54:1996(R) 2005 and not mate with ANSI/HIMA MD70.1 or ISO 594/1 and ISO 594/2 standards for intravenous ports and connectors; and wherein the male connector end includes a locking tab and is configured to only mate with specified connector ends for enteral feeding and is configured for insertion into a female end of a fluid delivery device or the connector having an axially aligned channel and a perpendicularly aligned locking region and wherein the channel and locking tab are configured to enable the male connector end to be inserted axially to a final depth prior to the fluid delivery device being turned and locked into place wherein the fluid deliver device has a second fluid delivery end that defines an internal conduit sized to limit a flow rate to a specified flow rate desired for a patient. ### Claim 12 (depends on 11) The syringe system of claim 11 further comprising a connector having a connector end configured to only engage with the male connector end with the locking tab to receive fluid from the syringe. ### Claim 13 (depends on 12) The syringe system of claim 12, the connector further including a port sized to meet enteral feeding system standards including ANSI/AAMI ID54:1996(R) 2005 and coupled to the enteral feeding tube wherein the port is operable to receive and engage with the male end of the fluid delivery device. ### Claim 14 (depends on 13) The syringe system of claim 13, the connector comprising a female connector end defining an outer diameter and a wall thickness that is too large to receive a syringe for I.V. delivery of medication with a Luer connector and an inner opening with a diameter too large to matingly receive and hold a male end of the syringe.
