Abstract
A system for enabling a medical device. The system includes a cradle having a magnet for generating a magnetic field. The cradle supports and aligns the medical device in a predetermined orientation. Medical device placed in the cradle exposes a magnetic sensitive switch to the magnetic field of the magnet that produces a change in state of the magnetic sensitive switch. Medical device further includes a switch, indicator, logic circuitry, delay circuit, and detect circuit for coupling a power source to electronic circuitry. In a first mode of operation the medical device can be turned on and then turned off. In a second mode of operation the medical device cannot be turned off after being turned on.
Claims20
A system for enabling a medical device having an internal power source comprising:
- a medical device having a magnetic sensitive switch;
- and
- a cradle having a magnet where the medical device is configured to decouple power from electronic circuitry in a first mode and where the medical device is configured to maintain power to the electronic circuitry in a second mode.
A method of enabling a disposable medical device having an internal power source for parameter measurement comprising:
- placing the medical device in proximity to a magnetic field above a threshold;
- coupling a power source to electronic circuitry of the medical device;
- maintaining the medical device within the magnetic field for a predetermined period of time;
- indicating that the medical device is enabled and the power source cannot be decoupled from the electronic circuitry;
- and
- ignoring further changes in magnetic field.
A method of enabling a medical device comprising the steps of:
- detecting a magnetic field above a threshold;
- coupling a power source to electronic circuitry of the medical device;
- initiating a power on reset of the electronic circuitry;
- and
- decoupling the power source from the electronic circuitry when the magnetic field falls below the threshold before a first time period.
