A multi-chamber syringe for delivering a plurality of fluids to a central venous catheter includes a barrel and a plunger. The barrel includes a plurality of chambers, and a first one of the plurality of chambers has a predefined volume of a saline flush stored therein. Actuation of the plunger causes the predefined volume of the saline flush to be dispensed from the barrel into the central venous catheter.

An infusion system includes a double action infusion pump. The pump includes a cylinder and a reciprocating piston received within the cylinder, the reciprocating piston separating a first pump chamber from a second pump chamber of the cylinder. A reciprocating motor is coupled with the reciprocating piston, and the first and second pump chambers alternate between filling and evacuating conditions with reciprocation of the reciprocating piston through operation of the reciprocating motor, and the speed of reciprocation is varied to provide a continuous output of fluid between the first and second pump chambers. A fluid source and a catheter are optionally coupled with the double action infusion pump. The catheter includes one or more infusion ports near a catheter distal portion, and the one or more infusion ports receive and expel the continuous output of fluid from the double action infusion pump.

Some embodiments provided herein relate to methods, systems and kits for providing consistent intracoronary administration of a biologic to subjects having diverse coronary anatomies. In some embodiments, the biologic is an adeno-associated virus serotype 1 (AAV1) vector encoding sarcoplasmic/endoplasmic reticulum ATPase 2a (SERCA2a) protein.

A method for the re-anticoagulation of platelet rich plasma in a blood apheresis system includes priming the blood apheresis system with anticoagulant, such that a volume of anticoagulant is transferred to a PRP container. The method may then transfer the anticoagulant within the PRP container to a red blood cell container, and collect a volume of platelet rich plasma within the PRP container. The platelet rich plasma may be collected in a plurality of cycles. Between collection cycles, the method may transfer a portion of the volume of anticoagulant from the red blood cell container to the PRP container.

An injector head with rotation mechanism allows selection between a state in which a syringe assumes a priming orientation with a through hole of the syringe positioned upper than the injector head body, and a state in which the syringe assumes a contrast agent injectable orientation with the through hole of the syringe positioned lower than the injector head body.

A valve is disclosed that has a body with an inlet, an outlet, and a needleless access port coupled to the body. The access port has an interior space and is configured to be actuated by a needleless connector. The inlet is selectively coupled to the outlet through the interior space such that fluid entering the inlet entirely flows through the interior space to the outlet.

An infusion pump system and method with common line auto flush, wherein the infusion pump system has a first reservoir, a second reservoir, a junction, a common line having one end in fluid connection with the junction and having a terminal fluid delivery end, and an infusion pump. The method includes infusing the first fluid at a first rate along a first flow path; entering a common line flush volume value for the common line; switching from the first flow path to a second flow path; driving the second fluid at the first rate along the second flow path; monitoring volume of the second fluid driven at the first rate; and driving the second fluid at a second rate along the second flow path when the monitored volume is equal to or greater than the common line flush volume value.

A drug solution administration apparatus includes an injection unit comprising an injection member configured to inject a drug solution; a delivery unit configured to be coupled to and decoupled from the injection unit, the delivery unit comprising: a delivery member configured to deliver the drug solution to the injection member, and a delivery device configured to deliver the drug solution to the delivery member; a detection unit configured to detect whether the injection unit and the delivery unit are coupled or decoupled; and a control unit configured to control operation of the delivery device. The control unit is configured to perform at least one of (i) restricting the filling operation when the detection unit detects that the injection unit and the delivery unit are coupled, or (ii) restricting the administration operation when the detection unit detects that the injection unit and the delivery unit are decoupled.

The present disclosure relates to a nutrition pump, an infusion set, a control valve and a method for controlling liquid comprising a pump body and an infusion set, wherein the infusion set comprises a control valve, and the pump body is mounted with a pump wheel; the control valve comprises a valve body and a valve core capable of matingly connected to the valve body, the valve body comprising a first input pipe and a second input pipe for connecting with the liquid to be infused, a cylindrical structure and an output pipe for outputting the liquid to be infused, one end of a coupling shaft is connected to a motor, and the other end is connected to the valve core so that the motor drives the valve core to rotate through the coupling shaft. The disclosure can realize the free switching of the two liquids, eliminate the risk of liquid leakage in the feeding process of the nutrition pump with a low cost and high precision.

A method of delivering a radioactive liquid includes, performing an initialization, including; extracting at least a first amount of a radioactive liquid from a source of radioactive liquid, measuring a radioactivity level for the first amount of radioactive liquid, and performing a calibration phase. The calibration phase includes, extracting a second amount of radioactive liquid from the source of radioactive liquid wherein the second amount is calculated based on the radioactivity level of the first amount to provide a total dose of radioactive liquid having a predetermined radioactivity level, and delivering the total dose and performing at least one more calibration and delivery phases.
