Abstract
A device and method for aseptically filling high pressure reservoirs in medicament pumps is disclosed. The device preferably includes a filter, a connector having a one-way valve and a filling tube with a terminal needle. The filter is connectable to a pharmacy prepared syringe containing a drug to be transferred to the reservoir of the IDIP. The filter is connected to the connector. The connector has a first and a second inlet port fluidly connected to an outlet port. A one-way valve is located in the connector “upstream” of the point where the two inlet ports connect to the outlet port. The filling tube is connectable to the outlet port. In use, a pharmacy syringe is connected to the first inlet port. A filling syringe is connected to the second inlet port. The filling tube is connected to the outlet port. The terminal needle of the filling tube is passed through the patient's skin and into the IDIP. The practioner draws the drug into the filling syringe from the pharmacy syringe through the connector. When the filling syringe is full, the practioner pushes the filling syringe plunger in thereby forcing the drug out of the outlet port, through the filling tube and terminal needle into the reservoir of the IDIP. The one-way valve prevents the drug from re-entering the pharmacy syringe.
