Many of those having diabetes take a combination of slow and fast acting types of insulin. It is important that different forms of medicament do not become confused and that the patient does not receive an incorrect medicament. In order to meet the appropriate standard, certain dimensional restrictions are placed upon the cartridge. A medicament cartridge that meets the requirements of this standard and permits more ready discrimination between medicament cartridges having different contents is provided. The medicament cartridge of the present invention is provided with an electrical element having specified electrical properties located on an external face of a displaceable plunger.
A medicament cartridge comprising a cylinder having a bottleneck at a first end, a fluid impermeable membrane secured across the first end and a displaceable plunger located internally of the cylinder towards a second end of the cylinder, a chamber defined by the displaceable plunger, the membrane and a region of the cylinder therebetween in which is stored a medicament to be dispensed, wherein the medicament cartridge is further provided with an electrical element having specified electrical properties located on an external face of tie displaceable plunger.
A medication delivery device wherein the medication delivery device is provided with electrical contacts for contacting the electrical element of a medicament cartridge according to any previous claim.
