Abstract: Disclosed are embodiments of electronic intravenous infusion pumps. In some embodiments, a medical infusion pump system can include a plurality of processors that are operationally isolated from each other. Some pump systems can include a modular electromechanical pump driver comprising a plurality of components that can be removed as a unit from within the pump housing without removing the components from each other. Some pump systems can include a handle formed as a unitary structure, the handle not including any portion of the boundary between panels of the pump housing. Some pump systems can include a memory within the pump housing that is configured to contain information about one or more pumping parameters for execution by at least two of the pump drivers. Some pump systems can include a connector configured to separately receive and secure each one of a plurality of different-sized IV pole stands.

Abstract: 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or a fully closed position and will not allow the carriage to dwell in an intermediate position if external force is withdrawn.

Abstract: 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.

Abstract: A disposable assembly for use with a sensor assembly, the disposable comprising 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 fluid pressure membrane is disposed along the fluid flow passage between the inlet and the outlet. The fluid pressure membrane is located between the lid portion and the base portion of the body.

Abstract: Disclosed is a foil dispensing machine for use in the process of hair coloring and highlighting. The machine can accommodate a commercially available roll of metal foil and includes a motor that can be used to unwind a piece of foil from the roll and dispense the piece from the machine. The machine further includes a cutter that is used to cut the dispensed foil from the remaining foil on the roll. The components of the machine are designed and positioned to reduce the likelihood that the foil will bunch up as it is being unwound from the roll. In some embodiments, the machine also includes a control device that can be programmed or adjusted to cause the machine to dispense foil in pre-set lengths. In some embodiments, the machine may be incorporated with a piece of furniture intended for placement in a hair salon.
