An LVP that provides peristaltic pumping to removably couplable administration set tubing assemblies supplying medical infusate. The LVP includes a housing, a drive-train assembly, and a controller. The housing includes an assembly receptacle configured to receive an administration set tubing assembly. The drive-train assembly provides mechanical peristaltic movement within the assembly receptacle. The drive-train assembly includes a stepper motor located within the housing and a camshaft assembly, driven by the stepper motor and at least partially extending into the assembly receptacle. The camshaft assembly includes a unitary camshaft and a plurality of tube engaging members that cooperatively move according to rotation of the unitary camshaft. Further, the controller is located within the housing that controls operation of the stepper motor and the camshaft assembly.

Infusion pump systems and methods for administration sets

A method for managing use of a disposable with an infusion pump is provided. The method can include adding validity information about a particular set of disposables to a list of disposables. Subsequent to adding the validity information, the method can include modifying the validity information about the particular set of disposables on the list of disposables. The method can include an infusion pump reading identifying information from a disposable, and can include determining whether the disposable is valid for use, based at least in part upon comparison of the identifying information read from the disposable by the infusion pump with the validity information about the particular set of disposables on the list of disposables. The method can also include the infusion pump making a determination of whether to deliver or not deliver an infusate based at least in part upon the determining whether the disposable is valid for use.

Medical device disposables information systems and methods

An infusion pump includes a pumping mechanism having at least one sensor and a pump motor and a pump control subsystem configured to control operation of the pumping mechanism, the pump control subsystem including a processor, a memory, and a startup module configured to drive the pump motor at a first rate, receive input from the at least one sensor, and drive the pump motor at a second rate based on the input received from the at least one sensor. Startup algorithms command an infusion pump to reach a targeted delivery rate or steady state in minimal time without requiring priming of the pump line or otherwise engaging in known methods of pump startup analysis.

Pump startup algorithms and related systems and methods

A method for associating medical devices is provided. The method can include providing a plurality of medical devices and each of the medical devices can include an accelerometer configured to measure spatial accelerations of the medical device. Each of at least two of the medical devices can measure with its accelerometer an acceleration pattern with respect to time. The method can include comparing for correspondence, according to defined correspondence criteria, the measured acceleration patterns, and associating all of the medical devices that measured acceleration patterns that satisfy the defined correspondence criteria. The method can also include modifying a parameter of each member of a set of devices that are associated.

Medical device association systems and methods

A dose request device for a medicament delivery device can include a housing, a dose request button, a short-range non-contact identifier, a communication interface configured to communicate with the medicament delivery device, and a controller. The short-range non-contact identifier can be configured to be capable of reading an identification code from a tag when the tag is disposed within a first range and not to be able to read the identification code from the tag when the tag is disposed beyond a second range. The controller can be configured and programmed to determine whether the identification code read by the short-range non-contact identifier matches any authorized identification code of a set of one or more authorized identification codes, and if so, and if the dose request button is pressed, the controller can then communicate a dose request to the medicament delivery device via the communication interface.

Dose request systems and methods

Various software features useable in a medical infusion pump are disclosed. In certain aspects, localized alarm and message handling systems are disclosed. In other aspects, variable intensity alarms are disclosed. In further aspects, cost tracking systems and methods for medical infusion pumps are disclosed. In still further aspects, methods and systems implementing a variable delay of pressure decay in a medical infusion pump are disclosed. In other aspects, methods and systems implementing a timed intermittent bolus by pressure are disclosed.
