Abstract

A delivery system for delivering fluidic media to a user having a second housing portion configured to be selectively operatively engaged with and disengaged from a first housing portion, the first housing portion and the second housing portion configured to be slidable relative to each other to operatively engage each other; and a fluid connector supported by one the housing portions in a position to engage a reservoir supported by an other of the housing portions in a case where the first housing portion and the second housing portion are slid relative to each other to operatively engage each other.

Claims

1. A medical device comprising:

a first device portion;

a second device portion configured to connect to a reservoir and to be selectively operatively coupled with the first device portion;

a drive device contained in the first device portion, the drive device arranged to selectively drive infusion media from the reservoir when the reservoir is connected to the second device portion and the first and second device portions are operatively coupled together;

a magnetic field source supported on the second device portion, the magnetic field source having a magnetic field;

a sensor supported on the first device portion for detecting the magnetic field of the magnetic field source when the first and second device portions are operatively coupled together;

electronics associated with the sensor and configured to control the drive device based, at least in part, on a detection of the magnetic field of the magnetic field source;

wherein the electronics are configured to determine whether a gauss level of the magnetic field detected by the magnetic field sensor is within a predefined range.

2. The medical device of claim 1, wherein the electronics are configured to control the drive device to inhibit operation of the drive device unless the magnetic field of the magnetic field source is detected by the sensor.

3. The medical device of claim 1, wherein the electronics are configured to provide a drive control signal to the drive device to selectively operate or inhibit operation of the drive device, based, at least in part, on the detection of the magnetic field of the magnetic field source.

4. The medical device of claim 1, wherein the electronics are configured to control a state of the drive device, depending upon whether or not the gauss level of the magnetic field is detected to be within a predefined range.

5. The medical device of claim 1, wherein the electronics are configured to inhibit operation of the drive device, in response to the sensor detecting the gauss level of the magnetic field being outside of the predefined range.

6. The medical device of claim 1, wherein the electronics associated with the sensor are configured to determine a direction of the magnetic field detected by the magnetic field sensor.

7. The medical device of claim 6, wherein the electronics are configured to control a state of the drive device, depending upon the direction of the magnetic field determined by the electronics.

8. The medical device of claim 6, wherein the electronics are configured to inhibit operation of the drive device, in response to the angle of the magnetic field detected by the sensor being outside of a predefined range.

9. The medical device of claim 1, wherein:

the magnetic field source provides a first field in a first direction, and a second field in a second direction different from the first direction; and

the magnetic field source and sensor are arranged relative to each other such that the sensor detects the first field in the first direction when the first device portion and the second device portion are operatively coupled together, and detects the second field in the second direction when the first device portion and the second device portion are in at least one state of not being operatively coupled together.

10. A method of making a medical device comprising:

providing a first device portion;

configuring a second device portion to connect to a reservoir and to be selectively operatively coupled with the first device portion;

containing a drive device in the first device portion, and arranging the drive device to selectively drive infusion media from the reservoir when the reservoir is connected to the second device portion and the first and second device portions are operatively coupled together;

supporting a magnetic field source on the second device portion, the magnetic field source having a magnetic field;

supporting a sensor on the first device portion for detecting the magnetic field of the magnetic field source when the first and second device portions are operatively coupled together;

configuring electronics associated with the sensor to control the drive device based, at least in part, on a detection of the magnetic field of the magnetic field source;

wherein configuring the electronics comprises configuring the electronics to determine whether a gauss level of the magnetic field detected by the magnetic field sensor is within a predefined range.

11. The method of claim 10, wherein configuring the electronics comprises configuring the electronics to control the drive device to inhibit operation of the drive device unless the magnetic field of the magnetic field source is detected by the sensor.

12. The method of claim 10, wherein configuring the electronics comprises configuring the electronics to provide a drive control signal to the drive device to selectively operate or inhibit operation of the drive device, based, at least in part, on the detection of the magnetic field of the magnetic field source.

13. The method of claim 10, wherein configuring the electronics comprises configuring the electronics to control a state of the drive device, depending upon whether or not the gauss level of the magnetic field is detected to be within the predefined range.

14. The method of claim 10, wherein configuring the electronics comprises configuring the electronics to inhibit operation of the drive device, in response to the sensor detecting the gauss level of the magnetic field being outside of the predefined range.

15. The method of claim 10, wherein configuring the electronics comprises configuring the electronics to determine a direction of the magnetic field detected by the magnetic field sensor.

16. The method of claim 15, wherein configuring the electronics comprises configuring the electronics to control a state of the drive device, depending upon the direction of the magnetic field determined by the electronics.

17. The method of claim 15, wherein configuring the electronics comprises configuring the electronics to inhibit operation of the drive device, in response to the angle of the magnetic field detected by the sensor being outside of a predefined range.

18. The method of claim 10, wherein:

the magnetic field source provides a first field in a first direction, and a second field in a second direction different from the first direction; and

supporting the magnetic field source and supporting the sensor comprises arranging the magnetic field source and the sensor relative to each other such that the sensor detects the first field in the first direction when the first device portion and the second device portion are operatively coupled together, and detects the second field in the second direction when the first device portion and the second device portion are in at least one state of not being operatively coupled together.
