Valves and medication delivery systems including valves are described herein. A valve includes a valve body and a valve element. The valve body defines a first flow path, a second flow path, and a catheter flow path. The valve element is disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, and is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position.

An infusion pump system and method provide concurrent infusion with common line auto flush. The infusion pump system has a first reservoir, a second reservoir, a junction, a mixing chamber, a common line having one end in fluid connection with the mixing chamber 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; determining a common line flush volume value for the common line; switching to a concurrent infusion mode to drive a combination of the first fluid and the second fluid at the first rate along a second flow path including the common line; monitoring a volume of the combination of the first and second fluids driven at the first rate; and driving the combination of the first and second fluids at a combined rate along the second flow path when the monitored volume is equal to or greater than the common line flush volume value.

The invention relates to a device for treating an individual suffering from cardiac or circulatory arrest or from a stroke, comprising a blood withdrawal device (BE) that is applied to the individual (P), an analysis unit (BA) which is directly or indirectly connected to the blood withdrawal device for detecting a blood analysis result (BAE) providing at least one characteristic of the blood, directly or indirectly connected to a blood return device (BR) that is applied to the individual (P) and is designed to deliver a substance to the individual via the return device (BR).

An infusion system and pump with configurable closed loop delivery rate catch-up including an infusion system having a medication management unit and a medical device. The medication management unit has programming code to: provide a graphical user interface for modifying a drug library; receive a catch-up rate factor; update the drug library with the catch-up rate factor; and transmit the updated drug library to the medical device. The medical device has programming code to: receive the updated drug library; receive a desired infusion rate; calculate expected accumulated infusion volume from the desired infusion rate; request delivery of the infusion at the desired infusion rate; determine actual accumulated infusion volume at a particular time; increase the infusion rate by the catch-up rate factor to generate a catch-up infusion rate when at the particular time the actual accumulated infusion volume is less than expected; and request infusion at the catch-up infusion rate.

An infusion system to provide concurrent TPN/insulin infusion including: a fluid administration set having a primary line in fluid communication with the TPN source, a secondary line in fluid communication with the insulin source, and a common outlet line; a pump operable to removably receive the fluid administration set, the pump being operable to concurrently move the TPN solution through the primary line in response to a TPN solution flow rate signal and the insulin solution through the secondary line in response to an insulin solution flow rate signal; and a flow controller operable to provide the TPN solution flow rate signal and the insulin solution flow rate signal to the pump. The flow controller is further operable to vary the TPN solution flow rate signal and the insulin solution flow rate signal to vary a ratio of TPN solution to insulin solution provided to the common outlet line.

An embodiment includes a system comprising: an artery, a vein, and a nerve; a first length of tubing adjacent at least one of the vein, artery, and nerve; a second length of tubing to couple to the first length of tubing; and a pump comprising a number of actuators; wherein when the system when operating is configured such that (b)(i) the second length of tubing couples to at least one of the number of actuators, (b)(ii) ends of the first and second lengths of tubing are closed, (b)(iii) a second end of the first length of tubing is operatively coupled to a second end of the second length of tubing, (b)(v) the pump pulsates fluid within the first length of tubing in response to the number of actuators intermittently contacting the second length of tubing.

A medical pump, comprising: a fluid housing having a plurality of intake openings, sealed by at least one intake valve, and an outlet opening sealed by an outlet valve; a piston which is sealing the fluid housing and connected to a drive mechanism, the drive mechanism pulls the piston to draw fluid from one of the plurality of intake openings and pushes the piston to discharge the fluid into the outlet opening; and a selecting valve enclosing at least two tubes, each providing fluid to one of the plurality of intake openings, wherein the selecting valve closes one of the at least two tubes while opening another of the at least two tubes.

A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

A method of pressure management for a drug delivery device including a pump, a fluid line, and a power source, includes: delivering fluid through the fluid line via the pump; determining a parameter indicative of pressure within the fluid line; determining whether the parameter indicative of pressure within the fluid line exceeds a pressure threshold level; pausing the delivery of fluid through the fluid line until a predetermined condition is satisfied; and resuming the delivery of the fluid through the fluid line after the predetermined condition is satisfied.

There is described a patch pump comprising a cartridge, a power source, a pump system, a drug delivery device and a control system configured to operate in particular the pump system and the drug delivery device. The pump system includes, on the one hand, a pump having a pump housing containing a pump piston and a valve piston and, on the other hand, a pump drive including a piston motor and a valve motor for driving the pump piston and the valve piston independently from each other through a first and a second transmission. The drug delivery device includes a transdermal delivery system having a needle actuation mechanism configured for transdermal insertion of a cannula.
