PROBLEM TO BE SOLVED: To solve the problem in which existing drug delivery pens require a large force to inject a medicament into an intradermal layer, thereby making the intradermal injection of the medicament difficult, and the problem in which drug delivery pen components can be damaged due to high pressure associated with the intradermal injection, thereby resulting in medicament leakage and dose inaccuracy.SOLUTION: A dual-chambered medicament delivery device (201) includes a first chamber (205) in which a medicament is stored. A dose setting member (213) is rotated to set a medicament dose. The dose setting member (213) is rotatable to set the medicament dose. The dose setting member (213) is not axially movable. A second chamber (221) is in fluid communication with the first chamber (205). The medicament dose is transferred to the second chamber (221) from the first chamber (205) prior to injecting the medicament dose. A needle (203) communicates with the second chamber (221) to inject the medicament dose into an injection site. |
