US 12,599,719 B2 · Closed system elastomeric pumping mechanism

Abstract

A medicinal infusion system includes a safety valve for isolating residual medication by providing a single point of fluidic disconnect to encapsulate a residual fluid volume prone to spillage. The safety valve couples a medicinal repository such as an infusion pump to a medicinal supply, typically from a syringe or tubing. The safety valve includes a resilient, deformable, or hinged surface for isolating and sealing the medicinal flow to eliminate and/or isolate any residual volume in tubing and connectors. The isolating surface accommodates an inserted fitting or coupling for allowing the medicinal flow to fill the infusion pump. Upon disconnection, fluids on either side of the safety valve are therefore isolated on the respective fill or source sides, and residual volume prone to spillage is eliminated.

Dependent claims

A medicinal infusion pumping device, comprising:

an expandable surround around a medicinal repository, the medicinal repository adapted to store a volume of fluid for intravenous injection based on an air pressure in the expandable surround;
a plurality of valves including a safety valve and a delivery side fluid disconnect securing a corresponding plurality of access ports in fluidic communication with the medicinal repository for metered patient delivery of the fluid, the access ports including at least an ingress port and a delivery port;
the delivery side fluid disconnect securing the corresponding delivery port providing fluidic communication from the medicinal repository to the patient;
and
each valve of the plurality of valves providing a single point of fluidic disconnect and enforcement of unidirectional flow to encapsulate the fluid in the medicinal repository for patient delivery.
