Medical Device Adapted To Detect Disengagement Of A Transcutaneous Device
First Claim
1. A drug delivery device (300, 600, 700, 1000) comprising, or being adapted to be connected to, a transcutaneous access device (951, 630, 730) adapted to be arranged subcutaneously in a subject, the drug delivery device further comprising:
- a reservoir (350, 620, 720) adapted to contain a fluid drug,an expelling assembly (330, 640, 740) adapted for cooperation with the reservoir to expel fluid drug out of the reservoir and through the transcutaneous access device,a controller (361, 650, 750) for detecting a first condition representative of the transcutaneous access device being arranged in a subcutaneous first position, and for detecting a second condition representative of the transcutaneous access device being arranged in a non-subcutaneous second position, whereinthe controller is adapted for performing an action corresponding to the detection of the second condition.

Abstract
The present invention provides a medical device comprising a transcutaneous device. The medical device further comprises a controller for detecting a first condition representative of the transcutaneous device being arranged in a subcutaneous first position, and for detecting a second condition representative of the transcutaneous device being arranged in a non-subcutaneous second position, wherein the controller is adapted for actuating an alarm when a condition representative of the transcutaneous device being arranged in a non-sub-cutaneous position is detected.

20. A method for operating a drug delivery device comprising a reservoir, an expelling assembly and a transcutaneous access device, comprising the steps of:
-
arranging the transcutaneous access device subcutaneously in a subject, operating the expelling assembly to expel fluid drug out of the reservoir and through the transcutaneous access device, detecting a property associated with operation of the expelling assembly, determining a first value or range for the property with the transcutaneous access device arranged subcutaneously, determining on the basis of the first value or range a second range indicative of the transcutaneous access device being arranged non-subcutaneously, performing an action when a value or pattern for the property within the second range is detected during operation of the expelling assembly. - View Dependent Claims (23, 25)
