초록 ▼

The present invention relates to an indicating device for use with medical injection devices for administering a drug into the body of a subject user wherein the indicating device is configured for indicating after administration that a dose of the drug actually has been administered and for maintaining this indication until lapse of a pre-defined time interval. The time delay indicator disclosed is based on a mechanical time delay device and includes a visual indicator that is controlled by the mechanical time delay device for signalling the status of the device during lapse of the pre-defined time interval.

1. A medical injection pen for introducing a drug into the body of a subject user, the medical injection pen comprising: a medicament filled cartridge comprising a piercable sealing member and a slidably mounted piston,a delivery mechanism including an actuator for the dispensing of drug responsive to activation of the actuator, anda time delay indicator adapted to change from a first visual state prior to activation of the actuator to a second visual state responsive to activation of the actuator, and to change to a third visual state after lapse of a pre-defined time interval subsequent to activation of the actuator, wherein the time delay indicator comprises a mechanical time delay device which is started responsive to activation of the actuator and which operates until lapse of said pre-defined time interval, the visual state of the time delay indicator being controlled by the mechanical time delay device, wherein the mechanical time delay device comprises; a first part attached to or integral with the actuator of the delivery mechanism,a second part, the second part being relatively moveable with respect to the first mechanical time delay part, wherein the second part is adapted to be manipulated by the operator from an inactivated position into an activated position for activating the mechanical time delay device and the actuator for causing the time delay indicator to change from the first visual state to the second visual state,wherein the pre-defined time delay is longer than 30 minutes,wherein the first part and the second part are adapted to move continuously or intermittently relative to each other during lapse of said pre-defined time interval,wherein a variable sized chamber adapted to contain a flowable medium is coupled between the first part and the second part, the variable sized chamber being closed by a flow control structure for controlling the rate of flow of the flowable medium through the flow control structure into and/or out of the variable sized chamber, andwherein a biasing mechanism is adapted to operate the time delay device during lapse of a pre-defined time interval by exerting a force to expand or reduce the variable sized chamber. 2. A medical injection pen as defined in claim 1, wherein the time delay indicator comprises a visual indicator coupled mechanically or integrated into one of said first part and second part and wherein the visual status of the visual indicator is adapted to change upon movement of one or more of said first part and second part. 3. A medical injection pen as defined in claim 1, wherein the time delay device is configured so that it is exclusively activated when a triggering force acting on the second part exceeds a minimum injection force defined as the minimum force required for activating the actuator and/or when the relative movement between the first part and second part exceeds a pre-defined minimum distance. 4. A medical injection pen as defined in claim 1, wherein the biasing mechanism is selected from the group consisting of a spring, an elastomeric member and a compressible or expandable pneumatic reservoir. 5. A medical injection pen as defined in claim 1, wherein the third visual state corresponds to the first visual state. 6. A medical injection pen as defined in claim 1, wherein the time delay indicator is configured to continuously or intermittently change state after activation of the actuator and until lapse of the pre-defined time interval so as to provide a measure of elapsed time since activation of the actuator. 7. A medical injection pen as defined in claim 1, wherein the variable sized chamber comprises a check valve which opens during activation of the actuator. 8. A medical injection pen as defined in claim 1, wherein the pre-defined time delay is longer than 1 hour. 9. A medical injection pen as defined in claim 8, wherein the pre-defined time delay is longer than 2 hours. 10. A medical injection pen as defined in claim 9, wherein the pre-defined time delay is longer than 3 hours. 11. A medical injection pen as defined in claim 10, wherein the pre-defined time delay is longer than 5 hours. 12. A medical injection pen as defined in claim 11, wherein the pre-defined time delay is longer than 24 hours. 13. A medical injection pen as defined in claim 12, wherein the pre-defined time delay is longer than 36 hours.
