A differential pressure based flow sensor assembly and method of using the same to determine the rate of fluid flow in a fluid system. The sensor assembly comprises a disposable portion and a reusable portion. A flow restricting element is positioned along a fluid flow passage between an inlet and an outlet. The disposable portion further has an upstream fluid pressure membrane and a downstream fluid pressure membrane. The reusable portion has an upstream fluid pressure sensor and a downstream fluid pressure sensor. The upstream fluid pressure sensor senses the upstream fluid pressure at a location within the fluid flow passage between the inlet and the flow restricting element. The downstream fluid pressure sensor senses the downstream fluid pressure at a location within the fluid flow passage between the flow restricting element and the outlet. The process utilizes output of the sensors to calculate the flow rate of the fluid.

Differential pressure based flow sensor assembly for medication delivery monitoring and method of using the same

A medicament container having an opening that provides access to a cavity defined by the medicament container. A stopper is sealingly positioned within the opening of the medicament container and configured to be forced into the cavity to open the medicament container. The medicament container also includes a mating member configured to mate with a complementary receiver associated with a second container to connect the medicament container to a second container. The medicament container further includes a radial seal configured to engage and seal against an interior seal wall associated with a second container prior to the stopper being forced into the cavity defined by the medicament container. A system is also provided for establishing fluid communication between a first container and a second container. The system includes a first container (e.g., a medicament container) having a radial seal, a second container, and a port assembly.

Medicament admixing system

A system for mixing the contents of a first container with the contents of a second container. The second container has a port assembly for receiving the first container. The port assembly has an actuator that is constructed to access the cavity of the first container during activation of the system and to allow fluid communication between the first container and the second container. The port assembly further includes a movable plug that provides a seal for the second container. The plug is configured to move axially relative to the actuator during activation of the system, thereby opening the seal of the second container and providing fluid communication between the first container and the second container.

A port assembly for enabling contents of a first container to be mixed with contents of a second container. The port assembly has a port housing that is configured to receive a first container. The port assembly further includes an actuator axially fixed within a cavity of the port housing. The actuator is configured to open a first container by forcing a stopper sealing an opening of a first container into a cavity of a first container during activation.

A system for mixing or reconstituting a drug contained in a first container with a diluent or fluid contained in a second container. The second container has a port docking assembly for engaging the first container. The first container is rotatable and axially slidable within the port docking assembly. The port docking assembly has an actuator to urge a stopper fluidly sealing the first container into the interior of the first container. The port docking assembly further includes a movable plug constructed to fluidly seal the second container in a first, docked position and to provide access to the interior of the second container in a second, activated position, whereby fluid communication between the first and second containers is provided when the first and second containers are in the second, activated position.

A medical pump includes a chassis having a fixed seat and a carriage having a footing for receiving a fluid delivery device and restricting its movement. An actuator assembly is provided that allows for moving the carriage between an opened and closed position to engage the fluid delivery device to the seat. A rack and pinion system is utilized in combination with a cam element and spring element to provide a bi-stable actuator assembly that urges the carriage into a fully opened position or a fully closed position and will not allow the carriage to dwell in an intermediate position if external force is withdrawn.

Fluid delivery device identification and loading system

A disposable assembly for use with a sensor assembly comprises a body, a flow restricting element, and a fluid pressure membrane. The body has a lid portion and a base portion. The body defines a fluid flow passage that forms an inlet and an outlet. The flow restricting element is positioned in the fluid flow passage between the inlet and the outlet. The membrane is located between the lid and base portions along the fluid flow passage. A reinforcing structure, such as a ring or a rigid disk, is positioned between the fluid pressure membrane and the lid portion to provide increased resistance to pressure in the fluid flow passage. The ring or disk can be a separate component or formed on the membrane. The membrane thickness adjacent to sensor access openings in the lid portion can be increased for pressure resistance, too.

Cassette for use in a medication delivery flow sensor assembly and method of making the same

A point of care fluid testing system for determining properties of a fluid comprises a patient connection, a primary fluid routing portion, a pump, a secondary fluid routing portion, and a flushing fluid connection. The patient connection connects the system to a patient. The primary fluid routing portion has a pump region, a fluid transfer region, and an in-line testing region. The pump region pumps the fluid sample from the patient to the testing portion and back to the patient. The in-line testing region evaluates a first characteristic of the fluid sample. The fluid transfer region transmits a portion of the fluid sample out of the primary fluid routing portion. The secondary fluid routing portion includes an off-line testing portion that receives the portion of the fluid sample transmitted from the fluid transfer region. The off-line testing portion evaluates a second characteristic of the fluid sample.

Automated point-of-care fluid testing device and method of using the same

A differential pressure based flow sensor assembly and method of using the same to determine the rate of fluid flow in a fluid system. The sensor assembly comprises a disposable portion, and a reusable portion. A flow restricting element is positioned along a fluid flow passage between an inlet and an outlet. The disposable portion further has an upstream fluid pressure membrane and a downstream fluid pressure membrane. The reusable portion has an upstream fluid pressure sensor and a downstream fluid pressure sensor. The upstream fluid pressure sensor senses the upstream fluid pressure at a location within the fluid flow passage between the inlet and the flow restricting element. The downstream fluid pressure sensor senses the downstream fluid pressure at a location within the fluid flow passage between the flow restricting element and the outlet. The process utilizes output of the sensors to calculate the flow rate of the fluid.

A method and pump that accurately senses air in a fluid delivery line pulses or activates and deactivates the air sensor(s) multiple times during the pumping phase of the fluid delivery cycle and can generate alarms based upon a single indication or a cumulative indication of air in the line. The pump can include multiple air sensors spaced along the delivery line so that the method can use the multiple signals therefrom to distinguish real moving air bubbles from false positives and/or air bubbles adhered to the inner wall of the line.

System for reducing air bubbles in a fluid delivery line

A medical pump includes a chassis having a fixed seat, and a main carriage having a carriage footing for receiving a fluid delivery device and restricting its movement. An actuator automatically moves the main carriage between open and closed positions to engage the fluid delivery device to the seat. The seat establishes the position of both the main carriage and fluid delivery device in the closed position. The actuator is connected to the main carriage by a rear carriage assembly having a manual release element for disengaging the actuator from rear carriage assembly and thereby from the main carriage. A processing unit detects jam conditions by processing carriage position data and electrical load data from the actuator.
