Embodiments are directed to portable infusion devices, systems, and methods of using the same for dispensing materials. In some cases, the devices, systems and methods may be used for infusing a material such as medicament, e.g., insulin, into a body in need thereof.

Infusion pump systems and methods

A storage tray for one or more syringes includes a recess for each of the syringes to be held in the tray. Each recess has first and second opposed sidewalls that define a space therebetween for receiving the barrel of the syringe. Each of the first and second sidewalls has one or more deformable projections thereon that protrude into the space between the sidewalls for positively retaining the barrel of the syringe between the first and second sidewalls. Additionally, a slot is provided for receiving the thumb rest of the plunger. The slot includes a third sidewall oriented generally transverse to the first and second sidewalls, with the third sidewall including a further projection for engaging a surface of the thumb rest. Preferably, a plurality of such transverse slots is provided to accommodate different positions of the plunger relative to the syringe barrel. The tray also includes a relieved portion intermediate the first and second sidewalls and the slot that provides access to a proximal portion of the syringe barrel to facilitate removal of the syringe from the tray.

Syringe storage tray

A storage system is provided. The system may include a tray having at least one recess in which at least one syringe is disposed, the syringe including a barrel with first and second barrel ends, and a stopper fixedly disposed between the first and second barrel ends. A tool attached to the stopper through the second barrel end, the tool having a first end attached to the stopper and a second end attached to or abutting the barrel or a surface of the recess, the first end being selectively adjustable relative to the second end to vary the distance between the first and second ends of the tool. In addition or in the alternative to the tool, the system may include a motion generator attached externally to the syringe, the motion generator being one of at least a vibration generator and a rotating frame.

A flow control valve includes a stem extending into an interior bore defined by a wall of a flow control member of the valve, the stem and the wall defining therebetween a cylindrical space allowing fluid communication between apertures formed in differing planes of the flow control member.

Multirate tubing flow control valve

A flow control valve for medical liquid is disclosed. The valve has a housing including an inlet, an outlet, and a flow path therebetween. A plurality of flow restrictors are located in the flow path to define a plurality of flow streams of differing flow rates. A flow control member is disposed in the flow path, and has a plurality of discrete apertures in a first region or plane and at least one aperture in a second region or plane spaced apart from the first plane. The flow control member is rotationally movable and defines an annular gap and radial groove which provide fluid communication between the different planes and the outlet regardless of the orientation of the flow control member. The flow control member may be rotated between a first position in which one of the plurality of apertures in the first plane is in communication with one of the flow streams to define a first flow rate through the valve, and a second position in which one of the at least one aperture in the second plane is in communication with a different one of the flow streams to define a second flow rate through the valve different from the first flow rate.

Multirate tubing flow restrictor

A valve is disclosed for dispensing a flowable material. The valve has a first chamber () at a first pressure wherein said first chamber () defines an outlet () in communication with said first chamber (). A second chamber () is at a second pressure. The valve has a stop () indexed against a third pressure, operating to selectively place the first chamber () into communication with the second chamber (). The stop () is operative to connect the second chamber () to said first chamber () when the first pressure is less than the third pressure.

Vacuum demand flow valve

A vacuum demand valve for delivering a flowable material is disclosed. The valve has a housing having a proximal end, a distal end, an intermediate segment therebetween defining a passageway wherein the flowable substance can flow from the proximal end to the distal end. The housing can be a tubing. A valve member is located along the intermediate segment. The valve member has a closed condition wherein the flow of the flowable material from the proximal end to the distal end is stopped and an open condition wherein the flow of the flowable material from the proximal end to the distal end is unstopped. The valve member is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway for placing the valve member in the open condition.
