Abstract
Systems and associated methods are provided for improving detection and measurement of elements in a medium, particularly the measurement of gaseous bubbles in liquid medium, such as blood injected into a patient's body. The systems include a radiation emitter to emit radiation for traversing through a medium, and an analyzer subsystem to receive and to analyze the traversed radiation for presence and/or absence of gaseous elements in the medium. The methods include receiving at least one collection of data corresponding to at least one emitted radiation traversed through a medium, analyzing said collection of data for at least one predetermined condition; and generating a response upon detection of at least one predetermined condition.
Claims48
A system for use in a detector, said system comprising:
- at least one radiation emitter subsystem to emit at least one radiation emission for traversing through a medium;
- at least one analyzer subsystem to receive and to analyze said radiation for presence and/or absence of gaseous elements in said medium;
- a filtering subsystem to separate the emitted radiation from ambient radiation in said received radiation;
- at least one ambient-light-sample-and-hold subsystem to receive said received radiation in form of an electrical and/or optical signal and to determine ambient light components in said signal;
- at least one summation subsystem to receive said received radiation in the form of a representative electrical signal, to receive ambient light components in said signal from said ambient-light-sample-and-hold subsystem and to subtract said components from said signal;
- and
- at least one amplifier for amplifying said subtracted signal.
The system of claim 15, wherein said predetermined undesirable condition is indication of presence and/or absence of at least one gaseous bubble and/or gaseous columns in said reports.
A method for analyzing data to determine presence and/or absence of predetermined conditions in a medium, said method comprising:
- receiving at least one collection of data corresponding to at least one emitted radiation traversed through a medium;
- analyzing said collection of data for at least one predetermined condition wherein said analyzing includes separating said emitted radiation from ambient radiation in said received collection of data;
- and
- generating a response upon detection of at least one said predetermined condition wherein said response includes interrupting flow of operations and/or providing a warning,
- wherein said separating includes receiving said collection of data in the form of a representative electrical signal in at least one ambient radiation sample-and-hold circuit for determining an ambient radiation component in said collection of data;
- receiving said collection of data in the form of a representative electrical signal in at least one summation circuit, receiving said ambient light component in said signal from said ambient-light-sample-and-hold circuit and subtracting said ambient light component from said signal;
- and
- amplifying said subtracted signal utilizing at least one amplifier.
A method for sensing used in a detector, said method comprising:
- emitting at least one radiation emission, said radiation traversing through a medium;
- receiving and analyzing said traversed radiation for presence and/or absence of gaseous elements in said medium, wherein said analyzing includes separating said emitted radiation from ambient radiation in said received radiation;
- and
- generating analysis data based on said analyzing,
- wherein said separating includes:
- receiving said received radiation in the form of a representative electrical signal in at least one ambient-light-sample-and-hold circuit for determining an ambient light component in said signal:
- receiving said received radiation in the form of a representative electrical signal in at least one summation circuit, receiving ambient light component in said signal from said ambient-light-sample-and-hold circuit and subtracting said ambient light component from said signal;
- and
- amplifying said subtracted signal utilizing at least one amplifier.
