Abstract

Disclosed is a medical infusion device, such as an externally worn insulin pump, capable of being in remote communication with a controller or data acquisition unit such as a blood glucose meter. The disclosed medical infusion device includes a dual frequency antenna to facilitate communication with the remote device and the antenna is mounted using a spring-design that inhibits transmission of vibration to the antenna.

Claims

1. A drug delivery device comprising:

a housing; and

a radio frequency module disposed in the housing and configured for wireless data transmission, the radio frequency module comprising;

a dual-frequency antenna configured to operate in a first frequency range and a second frequency range; and

a transceiver mounted on a circuit board that is reversibly connected to the antenna by at least one spring connector.

2. The drug delivery device of claim 1, wherein the at least one spring connector is a pogo pin.

3. The drug delivery device of claim 1, wherein the antenna occupies the inner distal surface of the drug delivery device.

4. The drug delivery device of claim 1, wherein the first frequency range comprises wavelengths of between about 869.70 MHz and about 870 MHz and the second frequency range comprises wavelengths of between about 902 MHz and about 928 MHz.

5. The drug delivery device of claim 1, wherein the antenna is a planar inverted-F antenna.
