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 whether and to what extent at least a portion of the vascular access device has been cleaned.

Claims

1. A medical device, comprising:

a vascular access device for communicating with the vascular system of a patient, wherein the vascular access device comprises;

a body with a lumen;

a status indicator comprising a moveable member movable from a first position to a second position, wherein movement of the moveable member from the first position to the second position provides an indication of elapsed time from when the vascular access device was placed in use in an intravenous access system;

a septum coupled to the vascular access device; and

a second status indicator disposed on the septum and being selected from a group consisting of a thermochromic material, a pH sensor, an alcohol sensor, and a colored substrate.

5. The medical device of claim 1 further comprising an opening in the body.

6. The medical device of claim 5 wherein the moveable member is viewable through the opening in the body.

7. The medical device of claim 6 further comprising a spring in mechanical communication with the moveable member for urging the moveable member from the first position to the second position.

9. The medical device of claim 7 further comprising snap arms which hold the moveable member and temporarily resists the force of the spring.

10. The medical device of claim 7 further comprising a clamp which holds the moveable member and temporarily resists the force of the spring.

11. The medical device of claim 1, wherein the attachment structure includes a time sensitive adhesive.

12. The medical device of claim 1, further comprising an opening in the body of the vascular access device positioned on the body so that the moveable member is viewable through the opening in the body.

2. a vascular access device for communicating with the vascular system of a patient, wherein the vascular access device comprises;

a body with a lumen;

a status indicator including a moveable member movable from a first position to a second position within the body;

an attachment structure that attaches the movable member to the body in the first position for approximately a predetermined amount of time during the use of the vascular access device; and

a spring in mechanical communication with the movable member for urging the movable member from the first position to the second position.

3. The medical device of claim 2, wherein the attachment structure includes a time sensitive adhesive.

4. The medical device of claim 2, wherein after approximately a predetermined amount of time during the use of the vascular access device in an intravenous access system the attachment structure releases the movable member, allowing the movable member to move from the first to the second position.

8. A medical device, comprising:

a vascular access device for communicating with the vascular system of a patient, wherein the vascular access device comprises;

a body with a lumen, the body having an opening; and

a status indicator comprising a moveable member movable from a first position to a second position to provide an indication of elapsed time from when the vascular access device was placed in use in an intravenous access system, the moveable member being viewable through an opening in the body, a spring being in mechanical communication with the moveable member for urging the moveable member from a first position to a second position, and a time sensitive adhesive attached to the moveable member that temporarily resists the force of the spring.
