Pump systems are described. An example pump system may include a processing unit and a recess configured to receive a pump cartridge. The recess can include a plurality of cartridge engagement slots. The cartridge engagement slots can be configured for removably coupling the pump cartridge. The recess can also include a cartridge-facing surface with a positioning feature slot extending orthogonal to a general plane of the cartridge-facing surface.

Pump systems with positioning features

An auto-injector for injecting a fluid medicament into a patient from a pre-filled syringe requires a disposable cassette that is selectively engageable with the reusable injector. The syringe is latched onto the cassette, and the cassette is then engaged with the injector. Activation of the injector causes a first motor to move the syringe so its needle is extended from a concealed position inside the cassette for injection of the medicament. A second motor on the injector is then activated to expel fluid medicament from the syringe. Then, the first motor is again activated to withdraw the syringe into the cassette for disposal of the cassette/syringe after an injection.

System and method for an injection using a syringe needle

An autoinjector system for injecting a fluid medicament into a patient includes a re-usable autoinjector, and a disposable cassette loaded with a hypodermic syringe pre-filled with a fluid medicament. The autoinjector includes a first motor for injecting a needle of the hypodermic syringe into the patient and a second motor for expelling the fluid medicament from the syringe.

Autoinjector system

Pump cassettes, infusion systems, and methods are described. An example infusion pump system may include a cassette recess with one or more valve actuators that extend through a surface of the cassette recess to operate a corresponding valve in a fluid passageway of a pump cassette mounted in the cassette recess. The valve actuator may include a base portion, a shaft extending from the base portion through the surface, and a spring disposed on the shaft and extending along a portion of the shaft. The spring may be disposed interior to the back surface. The system may include first and second valve actuators configured to operate corresponding first and second valves located on opposing sides of a pump chamber of the fluid passageway. A piston may be configured to cooperate with the first and second valve actuators to pump a fluid through the fluid passageway.

Valving system for infusion cassette

Pump cassettes, infusion systems, and methods are described. An example pump cassette may include a rigid body comprising a frame portion, a base portion, a compliant membrane disposed substantially therebetween, and two opposing longitudinal edge sections. The rigid body may include a controllable fluid pathway defined in part by the compliant membrane and extending from an inlet port to an outlet port. The pump cassette may include a slider coupled to the two opposing longitudinal edge sections and longitudinally articulable with respect to the rigid body.

Pump cassettes with slider and infusion pump systems

Pump cassettes, infusion systems, and methods are described. An example pump cassette may include a rigid body including two opposing edge sections, an inlet port, an outlet port, and a controllable fluid pathway extending from the inlet port to the outlet port. The pump may include a slider coupled to the two opposing edge sections and articulable with respect to the rigid body; and a flow stop valve operably coupled to the controllable fluid pathway.

Pump cassettes with flow stop and infusion pump systems

Pump cassettes, infusion systems, and methods are described. An example pump cassette may include a rigid body comprising a frame portion, a base portion, a compliant membrane disposed substantially therebetween, and two opposing longitudinal edge sections. The rigid body may include a controllable fluid pathway defined in part by the compliant membrane and extending from an inlet port to an outlet port. The pump cassette may include a piston disposed at least partially within the rigid body such that movement of the piston varies a volume of a pump chamber defined within the controllable fluid pathway.

Pump cassettes with piston and infusion pump systems

Pump cassettes, infusion systems, and methods are described. An example pump cassette may include a rigid body comprising a frame portion, a base portion, a compliant membrane disposed substantially therebetween, two opposing edge sections, and an interface-facing surface. The rigid body may include a positioning feature arranged substantially orthogonal to a general plane of the interface-facing surface. The pump cassette may include a slider coupled to the two opposing edge sections and longitudinally articulable with respect to the rigid body.

Pump cassettes with positioning feature and infusion pump systems

A syringe adapter for holding various sizes of syringes. A syringe includes a tip, a barrel, a plunger, a flange, and a syringe axis extending from the tip to the plunger. An example syringe holder attaches to a fluid delivery system and includes a syringe clamp. The syringe holder holds a syringe stationary in the syringe clamp. The syringe clamp is offset from the fluid delivery system such that the syringe, or connections to the syringe, does not interfere with other components of the fluid delivery system. The syringe holder may include a support bar, which the syringe clamp can slide along. Alternatively, the syringe clamp may be rotatable.
