A fluid delivery system includes a fluid pump and a fluid management system. The fluid management system receives input indicating a fluid (such as including a drug, a therapy, etc.) of a particular type to be delivered to a recipient. The fluid management system maps the particular type of the fluid to a set of patient parameters to be monitored during the delivery of the fluid to the recipient. During the delivery of the fluid to the recipient, the fluid management system monitors feedback from the recipient for each of the patient parameters in the set. Based on the feedback, the fluid management system controls the delivery of the fluid to the recipient.

Fluid pump notification and control based on monitored feedback

Via communications with an association management resource, an operator of a respective fluid delivery system can associate a medical device (fluid pump) with a particular entity such as a patient, location, one or more other medical devices, the caregiver, etc. Thereafter, the operator of the fluid delivery system is able to better manage use of the fluid delivery system based on relevant medical information, which is accessible as a result of creating the association. For example, the association management resource gathers and stores information associated with the entity prior to the operator providing the input associating the fluid delivery system with the entity. After the operator of the fluid delivery system creates the association, the medical information associated with the entity is immediately available to the fluid delivery system and/or corresponding operator of the fluid delivery system.

Medical device management using associations

A fluid delivery apparatus includes controller hardware, a diaphragm pump, a positive displacement pump, and a fluid conduit extending between the diaphragm pump and the positive displacement pump. During operation, and delivering fluid to a downstream recipient, the controller hardware draws fluid into a chamber of the diaphragm pump from a fluid source container. The controller hardware applies pressure to the chamber of the diaphragm pump to output the fluid in the chamber of the diaphragm pump downstream through the fluid conduit to the positive displacement pump. During application of the pressure to the chamber and outputting the fluid in the chamber of the diaphragm pump downstream, the controller hardware activates the positive displacement pump to pump the fluid from the positive displacement pump to the downstream recipient.

Fluid flow control and delivery via multiple fluid pumps

A system includes: a fluid delivery pump and a network of multiple record management processing nodes. The fluid delivery pump is in communication with one or more of the record management-processing nodes in the network. At least a first record management processing node receives input indicating a fluid delivery event. The fluid delivery event indicates fluid delivery from the fluid delivery pump to a recipient. The record management-processing node identifies code pertinent to the fluid delivery event; the code includes criteria in which to validate the fluid delivery event. In response to validation of the fluid delivery event as specified by the criteria in the code, a resource such as the record management-processing node triggers a transaction associated with the fluid delivery event.

Fluid delivery event tracking and transaction management

A controller in a fluid delivery system controls magnitudes of pressure in a first volume and a second volume. The first volume is of a known magnitude. The second volume is of an unknown magnitude and varies. The controller estimates a temperature of gas in the first volume and a temperature of gas in the second volume based on measurements of pressure in the first volume and measurements of pressure in the second volume. The controller then calculates a magnitude of the second volume based on measured pressures of the gases and estimated temperatures of gases in the first volume and the second volume.

Fluid flow measurement and control

A controller controls a fluid pump to deliver primary fluid from a first source at a desired rate through a respective conduit to a recipient. The controller monitors a volume of the primary fluid injected into the conduit. Subsequent to injecting a predetermined amount of the primary fluid into the conduit, the controller i) discontinues injection of the primary fluid into the conduit and ii) injects a secondary fluid through the conduit to advance a remaining portion of the primary fluid in the conduit to the recipient. The controller advances the secondary fluid into the conduit until a desired amount of the primary fluid is delivered trough the conduit to the recipient. Injection of the secondary fluid to push the remaining portion of the primary fluid reduces waste associated with the primary fluid.

Injecting a supplemental fluid in a conduit to deliver a primary fluid

A fluid pump device includes an elastically deformable conduit, multiple volume displacement elements, and a controller. During operation, the controller controls movement of the multiple volume displacement elements (such as compensation volume displacement elements and occluding volume displacement elements) with respect to the elastically deformable conduit at different times to cause flow of fluid in the elastically deformable conduit downstream to a recipient. The controller controls movement of the multiple volume displacement elements to volumetrically balance: i) an input flow rate of input fluid conveyed from a fluid source downstream to an input of the elastically deformable conduit, and ii) an output flow rate of output fluid delivered from an output of the elastically deformable conduit downstream to a recipient.

Fluid pump providing balanced input/output flow rate

A fluid delivery system comprises: a control interface and multiple unique loading guides. The control interface of the fluid delivery system is configured to accept a fluid pump assembly. The multiple loading guides are retractable from the fluid delivery system to retain and control movement of a facing of the fluid pump assembly to contact the control interface on the facing of the fluid delivery system. In one configuration, the control interface is disposed in a cavity of the fluid delivery system; the multiple loading guides are disposed at locations in proximity to the cavity. The multiple loading guides can be configured to slidably retract in unison to support substantially orthogonal insertion of the fluid pump assembly into the cavity of the fluid delivery system.

In accordance with one embodiment, a controller in a fluid delivery system controls magnitudes of pressure in a first volume and a second volume. The first volume is of a known magnitude. The second volume is of an unknown magnitude and varies. The controller estimates a temperature of gas in the first volume and a temperature of gas in the second volume based on measurements of pressure in the first volume and measurements of pressure in the second volume. The controller then calculates a magnitude of the second volume based on measured pressures of the gases and estimated temperatures of gases in the first volume and the second volume.

An infusion management system includes an infusion management server configured for providing an order to an infusion device to administer an infusion and the infusion device. The infusion device may be configured for receiving the order, associating the order with a patient, and adjusting at least one setting according to the order. A method for administering an infusion, an interface for an infusion device and a computer program product are also disclosed.

Fluid delivery management in a fluid delivery network

A combination of a chamber wall and the flexible membrane defines a pump chamber in a diaphragm pump. The pump chamber includes one or more internal surfaces that are modified to include a pattern of a pattern of channel surface regions. The channel surface regions provide unobstructed pathways to a respective opening disposed on an internal surface of the chamber wall. For example, as discussed herein, presence of the channel surface regions ensures that the facing of the flexible membrane does not needlessly stick (as a result of residual suction) to an inside surface of the chamber wall during a portion of the pump stroke in which negative pressure is applied to a backing of the flexible membrane. In other words, the channel surface regions distribute relief pressure along the inside surface of the pump chamber wall.

Pump chamber including internal surface modifications

A system for controlled delivery of medicinal fluid includes a fluid pathway assembly defining a fluid pathway and including means for calculating a first calculated fluid flow rate using gas laws. The fluid pathway assembly has an inline flow sensor element received within the fluid pathway movable in response to fluid flowing in the fluid pathway. A flow control device is removably attached to the fluid pathway assembly and has a sensor for sensing a position of the inline flow sensor element in the fluid pathway, the position of the inline flow sensor element being representative of a second calculated fluid flow rate. The fluid pathway assembly includes a variable flow resistor adjustable to regulate a rate of fluid flow in the fluid pathway assembly. A drive mechanism attached to the flow control device is operably coupled to the variable flow resistor when the flow control device is attached to the fluid pathway assembly. The variable flow resistor is adjustable by the drive mechanism to achieve a target flow rate when the first calculated flow rate and/or the second calculated flow rate differs from the target flow rate.

Fluid control system and disposable assembly

A fluid delivery system includes a control interface and multiple unique loading guides. The control interface of the fluid delivery system receives a fluid pump assembly. The multiple loading guides are retractable from the fluid delivery system to retain and control movement of a facing of the fluid pump assembly to contact the control interface on the facing of the fluid delivery system. In one configuration, the control interface is disposed in a cavity of the fluid delivery system; the multiple loading guides are disposed at locations in proximity to the cavity. The multiple loading guides slidably retract in unison to support substantially orthogonal insertion of the fluid pump assembly into the cavity of the fluid delivery system.
