Abstract
A compact, nonelectric fluid dispenser for use in controllably dispensing beneficial agents such as propofol and dexmedetomidine hydrochloride to patients. The dispenser includes a fluid flow control assembly that precisely controls the flow of the medicament solution to the patient and embodies a collapsible drug container that can be filled in the field with the beneficial agents to be delivered to the patient. The unit-dose fluid dispenser of the invention is presented in a sterile and aseptic manner, where the drug has been pre-filled in the system, so that the practitioner cannot mistakenly give the wrong drug to the patient. The dispenser uniquely provides a more efficient medicament delivery system for procedure rooms, such as the endoscopy center, so that a greater number of patients can be treated per day at a higher standard of care with increased profits for the healthcare provider.
