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 medical device, comprising:

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

a body having a lumen, a portion of the lumen including a septum having a slit; and

a status indicator coupled to the body, the status indicator including a movable member having a first end and a second end, the first end being reversibly coupled to a first portion of the body and the second end being coupled to a second portion of the body via a spring member, wherein the status indicator provides an indication of elapsed time.

2. The medical device of claim 1, further comprising:

a second vascular access device having a proximal end and a distal end, wherein the distal end of the second vascular access device is introduced into the vascular system, and wherein the vascular access device is a connector affixed to the proximal end of the second vascular access device.

3. The medical device of claim 1, further comprising a time sensitive adhesive interposedly positioned between the first end of the movable member and the first portion of the body.

4. The medical device of claim 1, wherein the movable member of the status indicator includes a colored label.

5. A method of using a medical device comprising:

a. attaching a device having a status indicator to a vascular access device, said status indicator including a movable member having a first end and a second end, the first end being reversibly coupled to a surface of the device and the second end being coupled to a portion of the device via a spring member, the status indicator being activated upon commencement of usage;

b. observing change of the status indicator; and

c. cleaning or removing the device having the status indicator upon observing a physical movement of the movable member from a first position to a second position.

6. The medical device of claim 5, wherein observing change of the status indicator includes observing that the status indicator has changed color.

7. The medical device of claim 6, wherein the status indicator changes color in response to light.
