The bezel is sized and shaped to releasably receive a port assembly. The port assembly includes a connector that is oriented to releasably engage with a receptacle located within the main assembly and near the opening, and thereby form an operable connection between the connector and its receptacle (e.g., using a cable). The assembly optionally includes a gasket that is sized and shaped to rest between an edge of the port assembly and the bezel. The port assembly is releasably secured with one or more fasteners.

Abstract: An infusion pump includes a controller that controls the pump's operating states including an initiation state and a current operating state for an infusion. The infusion pump has a clock that tracks the time of the current operating state of the infusion and a memory in communication with the controller and the clock that stores pump settings. The infusion pump includes a primary power source that provides power to the controller, clock, memory, and other pump components required for pumping during an infusion. The pump also includes a backup power source that provides power to the controller, clock, and memory during interruptions in power from the primary power source.

Abstract: An ambulatory infusion peristaltic pump has a cam shaft controlled by an encoder magnet assembly including a diametrically polarized magnet and an injection molded plastic housing. The encoder magnet assembly is attached to the cam shaft by a pair of cantilever snaps that are a part of the housing and are keyed to the cams by an alignment pin such that the angular position of the magnet's poles corresponds to the orientation of the cams. The magnetic orientation is detected by an encoder printed circuit board assembly (PCBA) positioned within the ambulatory infusion peristaltic pump and communicates readings to a pump microcontroller that determines the speed of the drive shaft and the angular position of the magnet (and, in turn, the position of each cam) from the PCBA readings and controls the pump based on the determined speed and position data in accordance with pump parameter settings.

Abstract: An ambulatory pump and a battery compartment for use in an ambulatory pump. The ambulatory pump includes a pump, a controller coupled to the pump for controlling the pump to deliver fluid to a patient, and a battery compartment electrically coupled to the pump and the controller. The battery compartment defines a cavity for alternately receiving a battery pack and a plurality of household batteries. The battery compartment is covered by an access cover that includes one or more rotatable retaining members that allow for the cavity to accept and hold the battery pack or household batteries.

Abstract: Techniques are provided for identifying an infusion cassette of an infusion pump that are simple to implement yet sophisticated enough to convey pump parameter data to the infusion pump when the infusion cassette is inserted into a receptacle of the infusion pump. The infusion pump includes a pump that acts on tubing to pump fluid through the tubing and a receptacle configured to receive an infusion cassette. The tubing passes through the infusion cassette and engages the pump when the infusion cassette is fully inserted. A detection system identifies the type of infusion cassette and sets and/or limits infusion pump parameters based on the detected type of infusion cassette. The detection system includes sensors within the infusion pump that detect the presence/absence of holes or other types of markings (e.g., colored regions or textured areas) on the infusion cassette in order to determine the type of infusion cassette and associated pumping parameters.

Abstract: Infusion pump control safeguards are provided by using multiple controller cores to ensure proper operation of an infusion pump. Each controller core controls specific operations of the pump and is interconnected with each other to monitor the operation of the other controller cores. The controller cores may include a pump controller core, the supervisor controller core, a System Controller Core, and a User Interface Controller Core. The Pump Controller Core is dedicated to control pump motor movement. No other controller core has direct access to the pump motor with a limited exception of the supervisor controller core, which can stop power flow to the pump motor in the event any one of the other controller cores is determined to be behaving improperly.

Abstract: A cassette with free flow prevention for use with an ambulatory pump. The cassette includes a free flow prevention clamp and a housing. The free flow prevention clamp includes a clamping section having a first clamp side and a second clamp side. The housing supports the free flow prevention clamp and defines a channel for receiving a tube. The first and second clamp sides extend parallel to the channel and the clamping section extends across the channel. The free flow prevention clamp is configurable within the housing via an actuator assembly in an open condition that allows fluid flow through the tube when force is applied to the clamping section and in a closed condition that prevents fluid flow through the tube when the force is removed from the clamping section.

Abstract: A cradle securely mounts one or more infusion pumps to a pole without obstructing the display, buttons, or connector ports of the infusion pumps. A lower portion of the cradle includes connection pins sized/oriented to fit within respective connection holes of the infusion pump as well as an integrated strain relief mechanism for one or more cables. An upper portion of the cradle includes clamps for engaging a protrusion/ridge on a top surface of the infusion pumps. In a single cradle configuration, a recess within a back surface of the cradle mates with a pole clamp connector or a mounting bar in either a vertical or horizontal orientation. In a multiple cradle configuration, each cradle is secured indirectly to the pole clamp connector via a mounting bar and respective adapters. The mounting bar may be bent to introduce an offset between adjacent infusion pumps.

Abstract: A lockbox configured to securely mount an ambulatory infusion pump and a fluid bag containing an infusate to a pole securely stores and dispenses the infusate without impacting operation of the ambulatory infusion pump. A cradle is adapted to receive the ambulatory infusion pump. The lockbox is mounted to a pole by inserting screws from an interior of the lockbox housing through holes in the cradle and in the lockbox housing to terminate in a lockable pole clamp. The lockbox housing has an L-shaped configuration with first portion shaped and sized for the fluid bag and a second portion sized and shaped to accommodate the ambulatory infusion pump and to provide access to the ambulatory infusion pump for programming. The L-shaped configuration distributes weight evenly when the lockbox is mounted on the pole.

Abstract: Systems and devices for controlling the delivery of a fluid are described. A latch assembly for guiding a cassette into the recess of an infusion pump housing includes a rotatable actuator connected to a movable latch. The movable latch includes one or more latch prongs that engage with the cassette. As the actuator is rotated toward its closed position, the latch prongs guide the cassette into the recess. A spring-biased release assembly holds the latch assembly closed and facilitates a secure engagement between the cassette and the recess, thereby holding the flexible tubing within the cassette in a secure engagement with the infusion pump. The latch assembly includes a magnet and a sensor in the pump housing to detect whether the latch assembly is closed.

Abstract: An exemplary compounding system and method can include two pump heads for simultaneously drawing two different fluids from at least two separate input containers such that the at least two different fluids are mixed and distributed to an output container. The system can include a manifold that maintains separation of certain of the different fluids until after passing by a first pump and a second pump and/or additional pumps. A junction can be placed in the fluid line downstream of the first and second pumps and/or additional pumps such that all or some of the fluids are mixed prior to output to the output container. The method of using the system can include incorporating software that selects various fluids at certain times and sequences to ensure optimum efficiency and safety for the system, and can continue compounding actions even when an input supply container runs out or otherwise fails to supply a particular fluid/material.

Abstract: Multiple hardware and software external signaling safeguards are employed by an infusion pump to ensure proper operation and to prevent the possibility of overinfusion or underinfusion due to unauthorized signals. All communications with the infusion pump pass through a communications module, and a collection of interconnected controller cores process communications within the infusion pump. The communication module provides wireless and wired communication and manages all communications with the controller cores. Communication through the wired communication interface is only permitted when the infusion pump is not actively infusing. When the infusion pump is actively infusing, no communication via the wired communication interface is permitted. The validity of certificates from external wired and wireless signal sources are checked to ensure the source is authorized to communicate with the infusion pump. In addition, all communications are expected to utilize proprietary messaging protocols.

Abstract: An infusion pump includes a multi-tabbed graphical user interface (GUI) that guides the user to the next tab to select during programming of the infusion pump. The GUI includes tabs that correspond to categories of parameters for entry (e.g., patient information, drug information, infusion information). As the data is entered, the operator selects the tabs (moving from left to right) and enters required parameters until all required parameters have been entered. Due to the number of items presented under a particular tab, it may not be readily apparent to the operator when the operator has entered all required parameters and can move on to the next tab. Accordingly, the GUI presents an indicator (e.g., small triangle) on or adjacent the next tab as soon as the required fields are completed, which guides the operator and speeds up programming when the required fields constitute less than the total number of fields.

Abstract: An exemplary compounding method of controlling a compounding device to prepare an admixture of at least two distinct material sources can include examining material source solutions for incompatibility of the ingredients and operating a first and a second pump to prevent one of the incompatible source solutions from entering a common flow path. The processing method can detect degradation of a fluid line by evaluating one or more of calibration error rate data, cumulative volumetric flow data, or cumulative pump operation data. The processing method can also selectively transfer a first group of source solutions using the first pump, receiving pump data from one or more sensors that sense actions of the pumps, applying fluid correction factors and calculating discrete pump movements, the pump movements being indicative of an amount of source solution displacement by a pump, and operating the pumps to selectively dispense the source solution amounts according to a preparation order.

Abstract: A dialysis system with post dialysis aseptic blood return including a fluid source, a dialyzer, a pump, a venous line, an arterial line, a bridge line coupled between the venous line and the arterial line, and a fluid source line coupled between the fluid source and a fluid port of the arterial line downstream for the bridge line. Aseptic blood return after dialysis is performed by blocking the arterial line between the bridge line and the fluid port, unblocking the bridge line, unblocking the fluid source line, and operating the pump in a forward direction to produce fluid flow from the fluid source, through the dialyzer, and through the bridge line to force venous blood in the venous line toward the patient venous access and arterial blood in the arterial line toward the patient arterial access.
