A system for delivering fluid to a patient includes a hazardous material enclosure suitable for holding a first container comprising a first fluid, and a pump device capable of pumping the first fluid from the first container and a second fluid from a second container. The hazardous materials enclosure has a cap which includes a flexible sealing member that cooperates with the first container to create a biohazard seal during connection of the first container to the cap. The system further includes a mixing device associated with the pump for mixing the first and second fluids for delivering the fluid mixture to the patient.
