ABSTRACT:
A device and method for the infusion of medicinal fluid at a controlled flow rate to a wound site or the blood stream of a patient is disclosed. A pump delivers fluid under pressure from a fluid source through a continuous and substantially constant flow path and through a supplemental bolus dose flow path. A large volume bolus dose reservoir accumulates a large quantity of fluid from the bolus dose flow path and holds the fluid under pressure. A flow regulator controls the fill rate of the large volume bolus reservoir. The large volume supplemental bolus dose is released from the bolus reservoir upon patient activation of a valve. The release rate of the bolus dose is controlled by the decompression of an elastomeric sphere or spring chamber, by the pressure gradient at the valve and/or by optional flow control tubing. In one embodiment, a source of fluid under pressure is pumped at a continuous and substantially constant rate to a wound site or the blood stream of a patient and into a bolus syringe, which is capable of holding a large quantity of fluid under pressure. A plunger on the bolus syringe may be depressed to release a bolus dose of fluid into a chamber accumulator and then to the patient at a controlled release rate.
