Abstract

An integrated vascular delivery system having a frame configured to receive a catheter insertable in a patient to deliver fluid at an insertion site. The frame includes a first hub, a second hub, and a pair of flexible lateral members extending between the hubs and including a tubular lateral member. The system also includes a fluidic channel that fluidically communicates with the catheter, wherein the fluidic channel passes through the tubular lateral member and at least one of the hubs, and includes a fixed turnabout portion in which fluid flows in a direction different from that within the catheter. The first and second hubs provide anchoring points on the patient distributed around the insertion site and on opposite ends of the catheter, thereby anchoring the frame to the patient and stabilizing the catheter. A method is provided for using an integrated vascular delivery system.

Claims

1. An integrated vascular delivery system adapted to stabilize a catheter inserted at an insertion site on a patient, comprising:

a catheter hub configured to conform to a surface of the patient and configured to provide a first anchoring point on the patient, wherein the catheter hub comprises a proximal region and a distal region, and is configured to receive a catheter, at the proximal region, to transfer a fluid at the insertion site;

a fluidic channel that fluidly communicates with the catheter, wherein the fluidic channel is configured to pass through the catheter hub and provide a fluid path into the catheter;

a septum, coupled to the catheter hub on the distal region of the catheter hub such that a portion of the first anchoring point is positioned laterally from a distal region of the septum, said septum configured to receive a needle and to direct the needle into a portion of the fluidic channel and into the catheter, thereby facilitating insertion of the catheter at the insertion site; and

an extension tube, fluidically coupled to the fluidic channel by way of the catheter hub.

2. The system of claim 1, wherein the extension tube is indirectly coupled to the fluidic channel by way of a tubular lateral member coupled between the extension tube and the catheter hub.

3. The system of claim 2, wherein the integrated vascular delivery system is configured to operate in a folded configuration that allows the tubular lateral member to be held in place relative to the catheter hub in order to facilitate access, by the needle, into the septum.

4. The system of claim 3, further comprising a housing configured to be reversibly coupled to the catheter hub, wherein the system is configured to operate in the folded configuration upon retention of the tubular lateral member in place over the catheter hub by the housing.

5. The system of claim 1, further comprising a sensor coupled to the catheter hub and configured to measure at least one of a biometric parameter of the patient and a fluid parameter in relation to fluid flow within the fluidic channel.

6. The system of claim 1, wherein the septum is configured to prevent fluid leakage from the septum after the septum is penetrated by the needle, and wherein the integrated vascular delivery system further includes a flash chamber defined within the catheter hub between the septum and the portion of the fluidic channel.

7. An integrated vascular delivery system adapted to stabilize a catheter inserted at an insertion site on a patient, comprising:

a catheter hub configured to provide a first anchoring point on the patient, wherein the catheter hub comprises a proximal region and a distal region, and is configured to receive a catheter, at the proximal region, to transfer a fluid at the insertion site;

a fluidic channel that fluidly communicates with the catheter, wherein the fluidic channel is configured to pass through the catheter hub and provide a fluid path into the catheter; and

a septum, coupled to the catheter hub on the distal region of the catheter hub such that a portion of the first anchoring point is positioned laterally from a distal region of the septum, said septum, configured to receive a needle and to direct the needle into a portion of the fluidic channel and into the catheter, thereby facilitating insertion of the catheter at the insertion site.

8. The system of claim 7, wherein the septum directs the needle along a linear path through the catheter hub, into the portion of the fluidic channel, and through the catheter, in facilitating insertion of the catheter at the insertion site.

9. The system of claim 8, wherein the fluidic channel is coupled to the catheter hub, and wherein the system further comprises an extension tube, fluidically coupled to an external portion of the catheter hub and providing access to the fluidic channel within the catheter hub.

10. The system of claim 7, further comprising a reservoir within the catheter hub and sealed by the septum, wherein the reservoir is configured as a flash chamber to contain blood in a configuration wherein the catheter is inserted into the patient.

11. The system of claim 10, further comprising a sensor coupled to the catheter hub and configured to measure at least one of a biometric parameter of the patient and a fluid parameter in relation to fluid flow within the fluidic channel.

12. The system of claim 7, wherein the septum is configured to prevent fluid leakage from the septum after the septum is penetrated by the needle, and wherein the integrated vascular delivery system further includes a flash chamber defined within the catheter hub between the septum and the portion of the fluidic channel.

13. The system of claim 12, further comprising a tubular lateral member coupled to the catheter hub and in fluid communication with the fluidic channel, wherein the integrated vascular delivery system is configured to operate in a folded configuration that allows the tubular lateral member to be held in place over the catheter hub in order to facilitate access, by the needle, into the septum.

14. An integrated vascular delivery system adapted to stabilize a catheter inserted at an insertion site on a patient, comprising:

a catheter hub configured to provide a first anchoring point on the patient, wherein the catheter hub comprises a proximal region and a distal region, and is configured to receive a catheter, at the proximal region, to transfer a fluid at the insertion site;

a fluidic channel that fluidly communicates with the catheter, wherein the fluidic channel is fixed within the catheter hub and provides a fluid path into the catheter; and

an extension tube, fluidically coupled to the fluidic channel by way of the proximal region of the catheter hub.

15. The system of claim 14, wherein the extension tube is indirectly coupled to the fluidic channel by way of a tubular lateral member coupled between the extension tube and the catheter hub.

16. The system of claim 15, wherein the integrated vascular delivery system is configured to operate in a folded configuration that allows the tubular lateral member to be held in place relative to the catheter hub in order to facilitate access, by the needle, into the catheter during insertion of the catheter into the patient.

17. The system of claim 16, further comprising a housing configured to be reversibly coupled to the catheter hub, wherein the system is configured to operate in the folded configuration upon retention of the tubular lateral member in place over the catheter hub by the housing.

18. The system of claim 14, wherein the fluidic channel is defined within a plane through the catheter hub, and wherein the extension tube is configured to provide fluid flow from a direction parallel to the plane.

19. The system of claim 14, further comprising a septum, coupled to the distal region of the catheter hub, configured to receive a needle and to direct the needle into a portion of the fluidic channel and into the catheter, thereby facilitating insertion of the catheter at the insertion site.

20. The system of claim 19, wherein the septum directs the needle along a linear path through the catheter hub, into the portion of the fluidic channel, and through the catheter, in facilitating insertion of the catheter at the insertion site.
