ELECTRONICALLY MONITORED INJECTION DEVICE
First Claim
1. A medical injection device for injection of set doses of a medicament from a medicament container, the injection device being adapted for operating in a dose setting mode and in a dose administration mode, the injection device comprising:
- a drive member which moves during dose setting mode and/or during dose administration mode,a dose sensor arrangement adapted to sense positional information associated with the drive member,a dosing actuator reversibly actuatable from a first state for operating the device in the dose setting mode to a second state for operating the device in the dose administration mode,a switch arrangement adapted to sense positional information associated with the dosing actuator, anda controller coupled to the dose sensor arrangement and to the switch arrangement, the controller being adapted to provide an electronic mode representation of the mode of operation and being adapted to determine the size of a set dose and/or an expelled dose,wherein responsive to the dosing actuator moving from the second state to the first state, the electronic mode representation is configured to enter dose setting mode after a time delay following detecting the dosing actuator has moved away from said second state or detecting the dosing actuator has moved into said first state and wherein the size determination of a set dose and/or an expelled dose is based on the electronic mode representation.

Abstract
Medical injection advice adapted for operating in a dose setting mode and in a dose administration mode, comprising a dosing actuator (124) reversibly actuatable from a first state for operating the device in the dose setting mode to a second state for operating the device in the dose administration mode, a switch (130, 132) adapted to sense positional information associated with the dosing actuator, and a controller coupled to the switch arrangement, wherein electronic mode representation is configured to enter dose setting mode after a time delay following detecting the dosing actuator has moved away from said second state or detecting the dosing actuator has moved into said first state.

8. A medical injection device for injection of set doses of a medicament from a medicament container, the injection device being adapted for operating in a dose setting mode and in a dose administration mode, the injection device comprising:
-
a drive member being adapted to expel a dose of medicament from the medicament container during dose administration, a dose sensor arrangement adapted to detect positional information of the drive member, a dosing actuator reversibly movable from a first state for operating the device in the dose setting mode to a second state for operating the device in the dose administration mode, a switch arrangement monitoring the position of the dosing actuator, and a controller coupled to the dose sensor arrangement and to the switch arrangement to determine the size of a set dose, wherein the switch arrangement and the controller is adapted to provide an electronic representation of transition into dose setting mode at a first position and to provide an electronic representation of transition into dose administration mode at a second position, the second position being different from the first position. - View Dependent Claims (9, 10, 11)
