1. A medical device, comprising:
- a power source;
a therapeutic assembly including electric circuits and at least one electromechanical component, wherein said assembly is adapted to use electricity from said power source to introduce a therapeutic substance into a body of a person whilst operating in a therapeutic mode, and is further adapted to enter a device sleep mode (DSM) during which mode said assembly is not introducing a therapeutic substance into a body of a person;
an accelerometer circuit mechanically linked to said therapeutic assembly and configured to, when the therapeutic assembly is in DSM, sense movements of said therapeutic assembly and to generate movement characterization data indicative of at least one sensed movement of said therapeutic assembly; and
a movement analysis module (MAM) configured to, during DSM, receive the movement characterization data from the accelerometer and to estimate whether a sensed movement of said therapeutic assembly represents a malfunction parameter requiring testing or recalibration of said assembly before a next use of said device, and triggering a disabling of said therapeutic assembly upon estimating a malfunction parameter.

Abstract
Disclosed is a medical device, including: a therapeutic component adapted to provide therapeutic functionality while in therapeutic mode and further adapted to enter a device sleep mode (DSM), an accelerometer configured to identify a movement characterization of the therapeutic component and a movement analysis module (MAM) configured to receive the movement characterization from the accelerometer and determine a malfunction parameter wherein the MAM is operable while the therapeutic component is in the DSM.

14. A medical device, comprising:
-
a therapeutic assembly comprising electromechanical components adapted to introduce a therapeutic substance into the body of a person; an accelerometer adapted to sense movement and orientation of the therapeutic assembly; a movement analysis module (MAM) comprising processing circuits configured to receive signals from said accelerometer indicating movement and orientation of the therapeutic assembly sensed by said accelerometer; and to trigger an alarm circuit if the signals received from said accelerometer match values indicating a malfunction; and triggering a disabling of said therapeutic assembly upon estimating a malfunction parameter. - View Dependent Claims (15)
