Abstract

A vascular access device for communicating with the vascular system of a patient may include a status indicator. The status indicator may detect and signal that a period of time has elapsed in relation to the use of the vascular access device.

Claims

1. A vascular access device comprising:

a body having a lumen through which a substance is introduced into the vasculature of a patient;

a channel within the body, the channel having a first end, a second end, a length, and inner dimensions;

a liquid absorbing material disposed within the channel;

a liquid source in fluid communication with the first end of the channel; and

the length and inner dimensions of the channel being configured so that a liquid from the liquid source moves from the first end of the channel through the liquid absorbing material to the second end of the channel in approximately a predetermined amount of time.

2. The vascular access device of claim 1, further comprising at least one window disposed between the channel and an external environment, the channel being visible through the window.

3. The vascular access device of claim 1, wherein the vascular access device is one of a catheter, a syringe, a Luer adapter, or an IV set.

4. The vascular access device of claim 1, further comprising a water soluble dye within the channel.

5. The vascular access device of claim 1, wherein the inner dimensions of the channel change along the length of the channel.

6. The vascular access device of claim 1, wherein the predetermined amount of time is approximately twenty four to thirty six hours.

7. The vascular access device of claim 1, wherein the liquid from the liquid source is a liquid flowing through the lumen and into the vasculature of the patient.

8. The vascular access device of claim 7, further comprising a water soluble dye within the channel.

9. The vascular access device of claim 8, wherein the channel is divided into segments along its length, each segment including a dye, the dye of each segment having a different color from the dye in the other segments.

10. The vascular access device of claim 1, wherein the liquid source is a liquid reservoir disposed on the body.

11. The vascular access device of claim 10, further comprising a breakable seal disposed between the liquid reservoir and the first end of the channel, such that when the breakable seal is broken, liquid from the liquid reservoir is in fluid communication with the channel.

12. The vascular access device of claim 10, wherein the liquid reservoir is disposed within a compressible chamber.

13. A vascular access device comprising:

a body;

a lumen within the body through which a liquid is introduced into the vasculature of the patient;

a channel within the body, the channel having a first end, a second end, a length, and inner dimensions;

a liquid absorbing material disposed within the channel;

the first end of the channel being in fluid communication with the lumen such that when a liquid is within the lumen, the liquid contacts the liquid absorbing material in the channel; and

the length and inner dimensions of the channel being configured so that the liquid within the lumen moves from the first end of the channel through the liquid absorbing material to the second end of the channel in approximately a predetermined amount of time.

14. The vascular access device of claim 13, further comprising a dye disposed within the channel.

15. The vascular access device of claim 14, wherein the dye is a water soluble dye.

16. The vascular access device of claim 14, wherein the dye is disposed within the liquid absorbing material.

17. The vascular access device of claim 13, further comprising a widow disposed between the second end of the channel and an external environment, the channel being visible through the window.

18. A vascular access device comprising:

a body having a lumen through which a substance is introduced into the vasculature of a patient;

a channel within the body, the channel having a first end, a second end, a length, and inner dimensions;

a liquid absorbing material disposed within the channel;

a liquid reservoir disposed near the first end of the channel;

a breakable seal disposed between the liquid reservoir and the first end of the channel, such that when the breakable seal is broken, liquid from the liquid reservoir is in fluid communication with the channel;

the length and inner dimensions of the channel being configured so that a liquid from the liquid source moves from the first end of the channel through the liquid absorbing material to the second end of the channel in approximately a predetermined amount of time.

19. The vascular access device of claim 18, wherein the liquid within the liquid reservoir is a colored liquid.

20. The vascular access device of claim 18, further comprising a widow disposed between the second end of the channel and an external environment, the channel being visible through the window.
