Abstract

A medical device comprising an infusion device comprising a fluid reservoir to contain a therapeutic fluid and a transcutaneous access tool fluidly coupled to the fluid reservoir, the transcutaneous access tool configured to deliver the therapeutic fluid subcutaneously to a patient; wherein the infusion device operates in a stand-by mode prior to the therapeutic fluid being introduced into the fluid reservoir; wherein the infusion device operates to deploy the transcutaneous access tool within a predetermined deployment time period upon filling the fluid reservoir to a predetermined fill level with the therapeutic fluid.

First claim

What is claimed is:

1 . A medical device comprising:
an infusion device comprising a fluid reservoir to contain a therapeutic fluid and a transcutaneous access tool fluidly coupled to the fluid reservoir, the transcutaneous access tool configured to deliver the therapeutic fluid subcutaneously to a patient; wherein the infusion device operates in a stand-by mode prior to the therapeutic fluid being introduced into the fluid reservoir; wherein the infusion device operates to deploy the transcutaneous access tool within a predetermined deployment time period upon filling the fluid reservoir to a predetermined fill level with the therapeutic fluid.

2 . The medical device of claim 1 wherein:
the predetermined deployment time period is greater than or equal to 30 seconds.

3 . The medical device of claim 1 wherein:
the predetermined deployment time period is less than or equal to 15 minutes.

4 . The medical device of claim 1 wherein:
the transcutaneous access tool introduction time period is greater than or equal to 1 minute, and less than or equal to 10 minutes.

5 . The method of claim 1 wherein:
the transcutaneous access tool introduction time period is greater than or equal to 2 minutes, and less than or equal to 5 minutes.

6 . The medical device of claim 1 wherein:
the infusion device comprises non-transitory memory including stored instructions that, when executed by at least one processor, cause the infusion device to deploy the transcutaneous access tool within the predetermined deployment time period.

7 . The medical device of claim 6 wherein:
the infusion device comprises at least one sensor, wherein the at least one sensor operates by sending an input signal to the at least one processor when the therapeutic fluid in the fluid reservoir reaches the predetermined fill level.

8 . The medical device of claim 7 wherein:
the at least one processor operates by detecting the input signal from the at least one sensor; and
upon detecting the input signal from the at least one sensor, the at least one processor operates to execute the instructions that cause the infusion device to deploy the transcutaneous access tool within the predetermined deployment time period.

9 . The medical device of claim 1 wherein:
the infusion device operates to deliver the therapeutic fluid in the fluid reservoir through the transcutaneous access tool after a predetermined infusion delay time period.

10 . The medical device of claim 1 wherein:
the infusion device operates to initiate the predetermined infusion delay time period when the transcutaneous access tool is deployed.

11 . The medical device of claim 10 wherein:
the predetermined infusion delay time period is at least 1 hour.

12 . The medical device of claim 10 wherein:
the predetermined infusion delay time period is at least 8 hours.

13 . The medical device of claim 10 wherein:
the predetermined infusion delay time period is at least 16 hours.

14 . The medical device of claim 10 wherein:
the predetermined infusion delay time period is at least 20 hours.
