Fluid delivery and infusion devices, and methods of use thereof
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.
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, and wherein, upon filling the fluid reservoir to a predetermined fill level with the therapeutic fluid when the infusion device is in stand-by mode, the infusion device generates a signal indicative that the fluid reservoir has been filled to the predetermined fill level with the therapeutic fluid,
wherein, upon generating the signal indicative that the fluid reservoir has been filled to the predetermined fill level with the therapeutic fluid, the infusion device uses the signal to cause automatic deployment of the transcutaneous tool once at least one processer detects the signal from at least one sensor that the fluid in the fluid reservoir has reached the predetermined fill level, and
wherein the automatic deployment of the transcutaneous tool occurs during a predetermined deployment time period, the predetermined deployment time period initiated by the occurrence of the filling of the fluid reservoir.
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 predetermined deployment 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 predetermined deployment 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 for the predetermined deployment time period, that when executed by the at least one processor, cause an instruction to be sent from the non-transitory memory to deploy the transcutaneous access tool within the predetermined deployment time period.
7. The medical device of claim 6 wherein: the at least one sensor operates by sending the 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 signal from the at least one sensor; and
upon detecting the 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.
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 9 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.
15. The medical device of claim 1 wherein: the transcutaneous access tool comprises a cannula.
16. The medical device of claim 1 wherein: the infusion device comprises an infusion pump.
