<p>A cartridge assembly for use in a pen-type medicament injector. The cartridge assembly comprises a cartridge for receiving a medicament suspension, the cartridge having a needle-pierceable outlet for the liquid medicament at one end thereof. A movable plunger positioned within the cartridge seals the other end. First and second mixing elements are provided within the cartridge to assist in mixing the medicament suspension. A first disk-shaped mixing element is disposed within the cartridge between the plunger and the outlet, the disk-shaped element being sized and shaped to permit its axial movement within the cartridge but to prevent any significant lateral movement. A second bead-shaped mixing element is disposed within the cartridge between the disk-shaped element and the outlet, the bead-shaped element being sized and shaped for free random movement between the disk-shaped element and the outlet.</p> |
