Abstract

A syringe pump system for delivering controlled delivery of fluids from a syringe. The syringe pump system includes a keyed coupling and a motorized syringe pump. The keyed coupling includes an identifiable key piece that identifies which application or area of therapy is desired. The syringe pump includes a pump housing, a sliding key bed for receiving and reading the identifiable key piece of the keyed coupling, and a plunger actuator for actuating a plunger of the syringe. An internal software may be used to determine the correct drug or nutritional libraries and syringe specifications preprogrammed into the pump.

Claims (23)

1. A syringe infusion pump for facilitating delivery of fluid from a syringe to a patient, the syringe infusion pump comprising a sliding key bed having a keyhole wherein the sliding key bed slides with respect to the pump, the keyhole being configured to receive a key piece of a keyed coupling, wherein the keyed coupling comprises a syringe connector at a first side and a tubing set connector on a second side, wherein the keyed coupling is configured to deliver fluid to one particular bodily system of the patient, and the keyhole being movable along a slide track such that the key piece remains received within the keyhole regardless of the length of the syringe.

2. The syringe infusion pump of claim 1 , further comprising a syringe connected to the first side and a tube or extension set coupled to the second side.

3. The syringe infusion pump of claim 1 , wherein analog or mechanical engagement of the key piece with the keyhole permits operation of the syringe infusion pump.

4. The syringe infusion pump of claim 1 , wherein the key piece comprises an identifiable element configured to control operation of the syringe infusion pump.

5. The syringe infusion pump of claim 4 , wherein the identifiable element is specific to the particular bodily system type of its attached keyed coupling, and wherein the syringe infusion pump is configured to identify the identifiable element and therefore accommodate the particular bodily system type.

6. The syringe infusion pump of claim 1 , wherein syringe infusion pump is configured to wirelessly verify the key piece when it is within a certain proximity to the syringe infusion pump, and wherein syringe infusion pump is inoperable when the key piece is beyond a predetermined distance or operation threshold from the keyhole.

7. The syringe infusion pump of claim 1 , wherein the keyed coupling is nonremovably connected to either the syringe at the first side or the tubing set on the second side.

8. The syringe infusion pump of claim 1 , wherein the keyed coupling is movable along a depth of the keyhole such that the syringe connector is connectable to the syringe regardless of an offset of a tip of the syringe.

9. A syringe pump-and-coupling system for connecting a syringe to a tube for delivering contents of a syringe to a patient in a precise and controlled manner, the syringe pump-and-coupling system comprising a syringe pump and a keyed coupling, the keyed coupling comprising:

a key;

a syringe connector at a first side and a tubing set connector on a second side, wherein each of the syringe connector and the tubing set connector are connectable with only syringes and tubing systems compatible with one particular bodily system of the patient; and

an identifiable element for being at least partially received by the syringe pump, wherein the identifiable element is configured for communicating data to the syringe pump, wherein the pump is configured to receive the data from the identifiable element and adjust its settings accordingly to safely and properly administer the contents of the syringe to said particular body system of the patient.

10. The syringe pump-and-coupling system of claim 9 , wherein the identifiable element is configured to communicate to the syringe pump at least one identifying datum to the syringe pump, wherein the identifying data includes at least the particular bodily system associated with the keyed coupling, a type of the syringe, a volume of the syringe, an identity of the contents within the syringe, or an amount of content to be administered to patient.

11. The syringe pump-and-coupling system of claim 9 , wherein the identifiable element is specific to the particular bodily system type of its attached keyed coupling.

12. The syringe pump-and-coupling system of claim 9 , wherein the identifiable element is an array of holes.

13. The syringe pump-and-coupling system of claim 9 , wherein the syringe pump comprises a housing having a sliding key bed slidably secured to the housing and configured to receive a portion of the keyed coupling.

14. The syringe pump-and-coupling system of claim 13 , wherein the syringe pump further comprises a motorized syringe plunger actuator configured to actuate a plunger of the syringe to dispense the contents of the syringe.

15. The syringe pump-and-coupling system of claim 9 , wherein the keyed coupling comprises a first coupler for connecting to a nozzle of the syringe, a second coupler for connecting to the tube, and a key piece provided between the first and second couplers.

16. The syringe pump-and-coupling system of claim 9 , wherein a position of a tip of the syringe and a length of the syringe is communicated to the pump based on a placement of a keyhole along a sliding key bed and a depth of the key into a keyhole.

17. The syringe pump-and-coupling system of claim 9 , wherein the syringe connector and the tubing set connector are compatible with syringes and tubing sets from an International Organization for Standardization (ISO) 80369-1:2018 series selected from: an ISO 80369-7:2021 intravascular syringe and tubing set, an ISO 80369-3:2016 enteral syringe and tubing set, and an ISO 80369-6:2016 neuraxial syringe and tubing set.

18. A syringe infusion pump comprising: a keyed access system reconfigurable based on data obtained from an identifiable element of a keyed coupling nonremovably connected to a tubing or a syringe comprising fluids to be administered, the syringe infusion pump comprising a sliding key bed having a keyhole wherein the sliding key bed slides with respect to the pump, the keyhole being configured to receive a key piece of the keyed coupling, wherein the syringe infusion pump is configured to selectively receive the data when the identifiable element is in close proximity to the pump.

19. The syringe infusion pump of claim 18 , wherein the identifiable element is logged with data when the syringe is filled with the fluids.

20. The syringe infusion pump of claim 18 , wherein the data received by the pump is selected from one or more of: a body system, body subsystem delivery route, tubing data, occlusion detection, light protection properties of the syringe, and characteristics of a fluid contained in the syringe.
