Infusion dispenser with adjustable flow rate regulator

Abstract

A liquid medicament dispenser for controlled infusion delivery of liquid medication to a patient. The dispenser includes an elastomeric bladder for housing the liquid medication, an inlet in communication with the bladder for receiving the liquid medication into the bladder, and an outlet in communication with the bladder for discharging the liquid medication into an infusion tube for delivering the liquid medication to the patient. A flow regulator for controlling flow rate of the liquid medication through the infusion tube includes a flow rate adjuster with a manually operable adjuster knob for setting flow rate and an encasement housing releasably securable about the adjuster knob for impeding access to the adjuster once the proper rate has been set. By so protecting the flow rate adjuster knob with the encasement housing, accidental or deliberate re-adjustment of flow rate, as may be caused by the patient, is minimized while advantageously providing medicinal treatment utility among most patients because of integral adjustability of flow rate control.
