Abstract

A medicament delivery device is disclosed having dose dial means 6,8 to determine a quantity of medicament to be delivered. The medicament delivery device is also provided with selection means to select whether the quantity of medicament to be delivered is determined as a multiple of a first quantum of units or as a multiple of a second quantum of units.

Claims

1. A medicament delivery device for self administration of a medicament by a patient comprising a dose dial means (6,8) to determine a quantity of medicament to be delivered is characterised in that the device is further provided with selection means to select whether the quantity of medicament to be delivered is determined as a multiple of a first quantum of units or as a multiple of a second quantum of units.

2. A medicament delivery device according to claim 1, in which the first quantum of units is whole units and the second quantum of units are half units

3. A medicament delivery device according to claim 1 or claim 2, in which the selection means comprises a switch or a combination of switches to be actuated by a user.

4. A medicament delivery device according to claim 1, in which the medicament delivery device further comprises a microprocessor 20 and a display 10 in which the selection means comprises an option provided on the display 10 to be selected by a user.

5. A medicament delivery device according to any previous claim, in which the medicament delivery device incorporates means to display to a user whether the selection means is operative to cause the dose dial means to determine the quantity of medicament to be delivered as the multiple of the first quantum of units or as the multiple of the second quantum of units.

6. A medicament delivery device according to any previous claim, in which one of the first or second quantum of units are half units.

7. A medicament delivery device according to any previous claim, in which the selections means may only be operated once during a predetermined period during the product life of the medicament delivery device.
