Method and device for displaying and metering doses as a product is administered
First Claim
1. A device for administering metered doses of a product, comprising:
- a reservoir for the product;
a dose metering device displaceable starting from an initial position in a metering direction along a dose metering distance in order to set a select dose of the product; and
a display unit for displaying a set dosage value, wherein the display unit displays a dosage value on the basis of a distance travelled by the dose metering device in the metering direction, which distance is determined from a reference point constituting a position assumed by the dose metering device after administering a dose or an initial position of the dose metering device in readiness for a first dose to be administered.

Abstract
A device and method for displaying and metering a product to be administered from a reservoir by means of a dose metering device and a display unit, wherein a specific dose is set by moving the dose metering unit from an initial position in a metering direction across a dose metering distance. A reference point is defined by an initial position of the dose metering device in readiness for administering a first dose or a position assumed by the dose metering device after administering a dose. The dosage setting displayed by the display unit is a dosage value based on the distance travelled by the dose metering device from the reference point in the metering direction.

2. A method of displaying and metering doses of a product to be administered from a reservoir by means of a dose metering device and a display unit, said method comprising the steps of:
-
moving the dose metering device starting from an initial position in a metering direction across a dose metering distance to set a selected dose;
defining a reference point by a position of the dose metering device assumed after administering a dose or by an initial position of the dose metering device in readiness for a first dose to be administered; and
displaying a dosage setting as a dosage value on the basis of the distance travelled by the dose metering device from the reference point in the metering direction.

3. A method of displaying and metering doses of a product to be administered from a reservoir by means of a dose metering device and a display unit, said method comprising the steps of:
-
a) in order to set a specific dose of the product, moving the dose metering device starting from an initial position (NPabs, A) in a metering direction across a dose metering distance (1a;
1b;
3a, 3a′
;
3b, 3b′
);
b) defining a reference point (NPrel) by a position of the dose metering device assumed after administering a dose or by an initial position (NPabs) of the dose metering device in readiness for a first dose to be administered; and
c) displaying a dosage setting as a dosage value on the basis of the distance (3b′
) travelled by the dose metering device from the reference point (NPrel) in the metering direction. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11)

13. A device for administering metered doses of a product, comprising:
-
a) a reservoir for the product;
b) a dose metering device displaceable starting from an initial position (NPabs, A) in a metering direction along a dose metering distance (1a;
1b;
3a, 3a′
;
3b, 3b′
) in order to set a specific dose of the product; and
c) a display unit for displaying a set dosage value, wherein the display unit displays a dosage value on the basis of a distance (3b′
) travelled by the dose metering device in the metering direction, which distance (3b′
) is determined from a reference point (NPrel) constituting a position assumed by the dose metering device after administering a dose (NPrel) or an initial position (NPabs) of the dose metering device in readiness for a first dose to be administered. - View Dependent Claims (14)

15. A method of administering a substance from an administering device comprising a reservoir containing the substance, a dose metering unit and a display unit, the method comprising the steps of:
-
selecting a dose of the substance to be administered by moving the dose metering unit from an initial position in a metering direction across a dose metering distance;
defining a reference point by an initial position of the dose metering unit in readiness for administering a first dose or a position assumed by the dose metering unit after administering a selected dose; and
displaying the selected dose on a display unit associated with the administering device wherein the displayed dose value is based on the distance travelled by the dose metering unit from the reference point in the metering direction.
