Abstract: A fluid container is encompassed by a custom fluid container pressure sleeve, which is configured to wrap around, connect and form to the malleable fluid container such that, when the fluid container pressure sleeve is inflated with a gas, the fluid container pressure sleeve applies an inward directional pressure to the malleable fluid container from an exterior of the malleable fluid container to compress the malleable fluid container. A pump connected to the fluid container pressure sleeve is activated to provide the gas to the fluid container pressure sleeve to compress the malleable fluid container and direct a fluid (e.g., the blood product) within the malleable fluid container toward and through a connected infusion tubing

Abstract: A method for transfusing blood using a syringe pump is disclosed. The method includes connecting a blood supply line to an upstream connection of a check valve, an intravenous transfusion line to a downstream connection of the check valve, and a syringe pump to a second upstream connection of the check valve, and activating the syringe pump to automatically retract and drive a plunger of the syringe pump, repeatedly, according to a pump rate programmed into the syringe pump according to the automatic retracting and driving of the plunger. By this mechanism, a blood product is automatically withdrawn from the blood supply line, through the check valve, and into a chamber of a syringe loaded into the syringe pump during each cycle of the automatic retracting of the plunger, and provided through the intravenous transfusion line from the chamber during each cycle of the automatic driving of the plunger.

Abstract: Syringes are described herein. In certain embodiments, a syringe includes a syringe body, a movable plunger, and a biasing member. The syringe body defines a cavity and a port in fluid communication with the cavity. The movable plunger is disposed within the cavity. The plunger and cavity define a volume. The port is in fluid communication with the volume. The biasing member is coupled to the plunger. The biasing member is configured to urge the plunger toward the port to dispense a fluid stored within the volume at a desired rate.

Abstract: A fluid flow disconnect sensor and alarm system includes first and second sensor units configured to be removably coupled to a first and second portions of a fluid connector assembly, respectively. The first sensor unit comprises a sensor configured to sense when the second sensor unit is within a threshold distance of the first sensor unit, and comprises a transmitter configured to transmit, to a device remote from the first and second sensor units, an indication regarding whether the first and second portions of the fluid connector assembly are coupled together responsive to the sensing. A computing device receiving the indication determines when the first and second portions of the fluid connector assembly are coupled together, and when the assembly becomes disconnected, and may generate an alarm when the first and second portions become disconnected.

Abstract: A system for controlled delivery of a medical fluid may include an elastomeric pump, a valve member fluidly coupled to the elastomeric pump at one side and a catheter at an opposite side for delivering the medical fluid to a patient, and tubing fluidly coupling the elastomeric pump and the valve member. The elastomeric pump may include an elastomeric membrane and a shell surrounding the elastomeric membrane. The pressure of the medical fluid may be greater than a pressure of the vein to keep the vein open. The valve member may be movable between an initial closed position, a fully open position where the medical fluid is delivered to the vein of the patient at a predetermined fluid flow rate, and at least one intermediate open flow position where the medical fluid is delivered to the vein of the patient at a flow rate below the predetermined fluid flow rate.
