Abstract

An injection device including a regulating element, a sensor, an electronic evaluation system connected to the sensor, and a display connected to the evaluation system for displaying information, wherein the sensor is arranged in the injection device or coupled to operational elements of the device whereby, during a delivery or operational process, the dose still to be delivered can be assessed. A method for displaying a dose of a substance to be delivered is encompassed by the present invention, the dose being detected and displayed during a regulating or operating process associated with an injection device, wherein an amount or dose of the substance still to be delivered is displayed during a delivery process.

Claims

1. An injection device comprising a regulating element, a sensor, an electronic evaluation system connected to the sensor, and a display connected to the evaluation system for displaying information, wherein the sensor is arranged in the injection device or coupled to operational elements of the device whereby, during a delivery or operational process, the dose still to be delivered can be assessed.

2. A method for displaying a dose of a substance to be delivered from an injection device, the method comprising the steps of detecting and displaying the dose during a regulating or operating process associated with the injection device, wherein a dose of the substance still to be delivered is displayed during a delivery process.

3. An injection device, containing a substance to be dispensed or in which an ampoule can be inserted, comprising operational elements, a setting element for setting a dose or quantity of the substance to be dispensed, a sensor for detecting a set dose, an electronic evaluation unit connected to the sensor and a display connected to the electronic evaluation unit and able to display the set dose, wherein the sensor is associated with the injection device such that a dose still to be dispensed can be sensed during a dispensing operation.

4. The injection device as claimed in claim 3, wherein the sensor is one of a rotary sensor or encoder, which can be coupled with at least one of the operational elements of the injection device, the movement or rotation of which is used in determining the dose set or still to be dispensed.

5. The injection device as claimed in claim 4, wherein the at least one operational element is one of a coupling sleeve or coupling element.

6. The injection device as claimed in claim 5, further comprising an electronic display.

7. The injection device as claimed in claim 4, further comprising a mechanical display comprising one, two or more coaxially disposed counting rings.

8. The injection device as claimed in claim 7, wherein at least two counting rings are coupled by a planetary gear.

9. The injection device as claimed in claim 3, further comprising at least one of an electronic and mechanical display illuminated by a light source.

10. The injection device as claimed in claim 9, wherein the light source is one of an LED or OLED.

11. A method of displaying a dose of a substance to be administered, set on an injection device or still to be dispensed from the injection device, the method comprising the steps of detecting and displaying the dose during a setting operation, wherein the quantity or dose of the substance to be administered which still has to be dispensed is also displayed during a dispensing operation.

12. The method as claimed in claim 11, further comprising the step of one of electronically or mechanically re-setting when an end of the dispensing operation or a change of ampoule is detected.

13. The method as claimed in claim 11, further comprising the step of switching on at least one of an electronic display and a light source of at least one of an electronic and mechanical display when it is detected that the injection device is being operated.

14. The method as claimed in claim 13, wherein the at least one of the electronic display and light source is switched off when a predefined period has elapsed after a deployment of the injection device has been detected or when it is ascertained that the injection device has not been deployed within a predefined period of time.
