Abstract

The application provides an assembly comprising a housing (20) having an electrical housing connector (50) and a strip port (40) for a BGM sensor arranged in the vicinity of the electrical connector. The assembly further comprises an external electrical connector (60) adapted for releasable connection to the housing connector, wherein the external electrical connector comprises a portion (62) adapted to block the port opening when the external electrical connector is connected to the housing connector, thereby preventing insertion of a strip in the port when the two connectors are connected to each other. In this way it is prevented in a simple and cost-effective manner that a patient via an inserted strip is subjected to a too high voltage or current supplied to the circuitry of the electronic device.

Claims

1. An electronic device assembly (5), comprising:

a housing (2) having an interior,

electric circuitry arranged in the interior,

an electrical housing connector (50) in communication with the exterior,

a port opening (40) arranged in the vicinity of the electrical connector,

an analyte sensor (190) arranged in the housing and in communication with the port opening, and

an external electrical connector (60) adapted for releasable connection to the housing connector, whereby in a situation of use an electrical contact can be established between the two connectors (50, 60),

wherein the external electrical connector comprises a portion (62) adapted to block the port opening when the external electrical connector is connected to the housing connector, thereby preventing insertion of an object in the port opening when the two connectors are connected to each other.

2. An electronic device assembly as in claim 1, further comprising a rechargeable power source (160) electrically connected to the housing connector.

3. An electronic device assembly as in claim 1, further comprising:

a charging apparatus (310) comprising;

an electric power source connector (311),

an electric outlet in communication with the external electrical connector (321),

electric power circuitry (312) connected to the power source connector and the electric outlet and adapted to change a characteristic of electric power supplied to the electric circuitry before being supplied the electric outlet.

4. An electronic device assembly as in claim 3, wherein the power circuitry is adapted to change the voltage.

5. An electronic device assembly as in claim 4, wherein the electric power source connector is a utility power plug (311).

6. An electronic device assembly as in claim 4, wherein the external electrical connector is connected to the electric outlet via a cable (320).

7. An electronic device assembly as in claim 1, wherein the sensor is a physiological analyte sensor.

8. An electronic device assembly as in claim 7, wherein the sensor is a glucose sensor adapted to receive a blood glucose test strip.

9. An electronic device assembly as in claim 1, wherein the port opening and the analyte sensor are adapted to receive a strip-formed member carrying a specimen to be analyzed by the sensor.

10. An electronic device assembly as in claim 1, wherein the portion (62) adapted to block the port opening (40) prevents incorrect connection of the two connectors.

11. An electronic device assembly as in claim 1, wherein the housing comprises one or more of the features from the group consisting of:

a display (30) for displaying an analyte value, keys (10, 21, 22) allowing a user to enter data and/or commands, a communication port (185) for transmitting and/or receiving data, a wireless receiver (180) for receiving data, a wireless transmitter (170) for transmitting analyte data, and a processor (110) for calculating patient treatment suggestions based on analyte sensor data.

12. A method of connecting an apparatus to an external electrical connector, comprising the steps of:

a) providing an apparatus comprising;

an electrical apparatus connector, and

a port opening arranged in the vicinity of the electrical connector,

b) providing an external electrical connector adapted for releasable connection to the apparatus connector, whereby in a situation of use an electrical contact can be established between the two connectors, wherein the external electrical connector comprises a portion adapted to block the port opening when the external electrical connector is connected to the apparatus connector, and

c) connecting the two connectors thereby preventing insertion of an object in the port opening when the two connectors are connected to each other.

13. A method as in claim 12, comprising the further step of:

before or after the two connectors have been connected, connecting the external electrical connector to an external power source to thereby charge a rechargeable power source arranged in the apparatus.
