Abstract

A medical appliance for use on and/or in the body of a user including a transmission unit and an activation switch connected to the transmission unit for activating the transmission unit when an activation signal is received by the activation switch. The invention encompasses systems and processes for transmitting data between a medical appliance and an external appliance, wherein, in some embodiments, the external appliance activates the medical appliance prior to data transmission when the latter is in an idle state.

Claims

1. A medical system comprising:

a) a medical appliance for use on or in a user'"'"'s body, comprising a transmitter/receiver unit and an activation switch connected to the transmitter/receiver unit wherein the switch can activate the transmitter/receiver unit when an activation signal is received from the activation switch; and

b) a remote control comprising a data input unit, an activation unit for activating the activation switch of the medical appliance and a transmitter/receiver unit able to exchange data with the transmitter/receiver unit of the medical appliance.

2. The medical system as claimed in claim 1, wherein the medical appliance comprises at least one of a sensor, a glucose sensor, an infusion system, a pump, an insulin pump or an injection pen.

3. The medical system as claimed in claim 1, wherein the remote control comprises a glucose measuring device.

4. The medical system as claimed in claim 1, wherein the activation switch comprises at least one of an induction coil, a magnetic switch, a reed contact, a microphone, a light-sensitive switch, a photo-diode or a mechanical switch.

5. The medical system as claimed in claim 1, wherein the activation unit comprises at least one of an induction coil and a permanent magnet.

6. The medical system as claimed in claim 1, wherein the remote control comprises a data output unit.

7. The medical system as claimed in claim 1, wherein the remote control comprises an interface for communicating with at least one of an electronic device, a PC, a mobile telephone or PDA.

8. A medical system comprising:

a medical device comprising a communication unit and an activation element connected to the communication unit wherein the activation element activates the communication unit; and

a remote control comprising a data input unit, an activation unit for activating the activation element of the medical appliance and a communication unit able to communicate with the communication unit of the medical appliance.

9. A method of using a medical system comprising the steps of:

providing a medical device comprising a communication unit and an activation element connected to the communication unit wherein the activation element activates the communication unit;

providing a remote control comprising a data input unit, an activation unit for activating the activation element of the medical appliance and a communication unit able to communicate with the communication unit of the medical appliance; and

placing the medical device and remote control in proximity sufficient for the communication units to communicate with each other.

10. The method according to claim 9, wherein when the communication units are not in communication, the medical device is in an idle state and may be activated by the remote control prior to the communication.
