Abstract

A device for preventing electrical shock from a device with electrical interfaces. A shutter or other barrier associated with the device that physically prevents access or contact to one of the electrical interfaces while another electrical interface is in use.

Claims

1. A continuous glucose monitoring system, the system comprising:

a continuous glucose monitoring device having an end portion and at least two electrical interfaces located on the end portion and accessible from the outside of the device, wherein each of the at least two electrical interfaces is associated with a different function of the device;

a barrier configured to connect to the device; and

a cable configured to connect to the device and to connect the device to a second device, to a power source, or to both a second device and a power source,

wherein the barrier comprises a shroud having a cavity configured to cover the end portion of the device and to cover the at least two electrical interfaces, wherein the barrier is configured to block a first of the electrical interfaces of the device and configured to not block a second of the electrical interfaces of the device when the barrier is connected to the device.

2. The system of claim 1, wherein the first electrical interface comprises a test strip port and the second electrical interface comprises a computer port or a power charging port, wherein the power charging port is connectable to a source of power.

3. The system of claim 1, wherein the first electrical interface comprises a test strip port and the second electrical interface comprises a computer port and a power charging port, wherein the power charging port is connectable to a source of power.

4. The system of claim 1, wherein the barrier is permanently connected to the cable.

5. The system of claim 1, wherein the barrier is detachably connected to the cable.

6. The system of claim 1, wherein the cavity has a form factor to receive the end portion of device therein.

7. The system of claim 1, wherein the cable comprises a grip configured for facilitating insertion and removal of the barrier with respect to the device.

8. The system of claim 1, wherein the continuous glucose monitoring device includes a display and the barrier is configured to not cover the display when the barrier is connected to the device.

9. The system of claim 8, wherein the first electrical interface comprises a test strip port.

10. The system of claim 8, wherein the second electrical interface comprises a computer port.

11. The system of claim 8, wherein the second electrical interface comprises a power charging port connectable to a source of power.

12. The system of claim 11, wherein the continuous glucose monitoring device includes a rechargeable battery that is rechargeable using the power charging port.

13. The system of claim 1, wherein the barrier comprises an insertion point.

14. The system of claim 13, wherein the cable is configured to pass through the insertion point.

15. The system of claim 1, wherein the barrier comprises a connector to connect the cable to the device.

16. The system of claim 15, wherein the connector is disposed at least partially within the cavity of the shroud.

17. The system of claim 15, wherein the second electrical interface comprises a port and the connector is configured to insert into the port.

18. The system of claim 17, wherein the port is a computer port, a power charging port, or both, wherein the power charging port is connectable to a source of power.
