| 摘要 |
Injection devices, systems and methods are disclosed for injecting two or more medicaments to a patient at a single injection site while preferably minimizing any mixing of the medicaments prior to delivery to the patient. The invention can also be used to sequentially deliver the medicaments to the patient in a repetitive manner. For example, the injection apparatus can sequentially provide a first medicament and then a second medicament to the patient during a first injection procedure. During a second injection procedure, the injection apparatus can again sequentially provide the first medicament and the second medicament to the patient either at the injection site of the first injection procedure or at a different injection site. Multi-lumen manifolds are disclosed for coupling to conventional drug ampoules, to permit the user to sequentially delivery different medicaments via a single skin penetration and to reduce losses associated with usage. Systems including multiple drug reservoirs and filling adaptors are also disclosed.
