2. System Description

Theory of Operation

The iChem100 is a semi-automated urine chemistry analyzer performing measurements of urine chemical constituents utilizing test strips. The iChem100 is a reflectance densitometer.

Features

The iChem100:
reads and interprets without operator variability
processes and analyzes urine strips with a throughput of 210
samples per hour
enables entry of microscopic results

Test Strips

enables automated urine color determination with up to twelve
programmed choices
reads ascorbic acid for interference detection
allows users to correct or compensate for urine discoloration
allows batch and stat mode for sample processing
The test strips have reagent-impregnated specialty paper pads to perform c
hemical analysis of:
bilirubin
urobilinoge
n
ketones
ascorbic acid
glucose
protein
blood
pH
nitrite
leukocytes
specific gravity
The advantage of this approach is ease of testing. The process requires that an operator dip the urine test strip with its reagent-impregnated pads into and out of a urine sample. This action brings the reagent­impregnated pads into contact with the urine containing the analytes to be

tested. Once the test strip has been dipped into the urine, color deve on each of the reagent-impregnated pads in direct proportion to th amount of analyte present in the sample. The test strips have a compensation pad to determine the color of the urine as fo

After the test strips are placed on the Test Strip Tray with correct orientation, they are automatically transported to the measurement window and the r the iChem100.

LED Unit
For the illumination of the measurement, a LED Unit with three differen wavelengths LEDs (450nm, 530nm and 625nm) is used. To increase homogeneity, the LED’s are not placed regularly over the measurement window but are placed mainly towards the outer area of the LED Unit. order to achieve a very high light intensity, one reflector and one anti­reflector are placed beside the LED e
ntire urine test strip is illuminated.

2. System Description
CMOS Image Sensor
Unlike most of the reflectometers in the market for urine test strip analysis, the iChem100 does not use a photodiode detector to measure the reflected light, but instead utilizes a CMOS (Complementary Metal Oxide Semiconductor) image sensor that captures a color image of each of the test pads. The CMOS image sensor is able to photograph almost the whole length (100mm) of the urine test strip and all of its width. As seen in the figure above, the CMOS image sensor has been placed perpendicular to the measurement level, and since the height of the instrument limits the optical length, a mirror has been used for changing the direction of the beam.
Optics Calibration
Prior to each measurement, the optics assembly is calibrated using a “fixed standard” and it permits a one-point calibration. The iChem100 is also capable of performing an internal, automated two-point calibration if the one-point calibration done before each specimen determination falls outside of the acceptable limits. A secondary “movable standard” is automatically moved into place and readings from it in conjunction with the “fixed standard” are used to perform a two-point calibration. No external calibration strips or procedures are required.
Measurement
Once calibrated, the urine test strip is sequentially illuminated by the LEDs (Red, Blue, Green) that are located at a 30 impregnated reagent pads, and the reflected signals are sent via the mirror through the lens and captured by the CMOS camera. The captured signal is evaluated and a completed result is provided for each of the chemistries.
The iChem100 uses a compensation pad to determine the color of the urine as well as correct for color interference on the impregnated reagent pads. Since the iChem100 is capturing a pixelized image of the blood pad, a special algorithm has been developed using more than a reflectance to differentiate between intact and hemolyzed red blood cells.

Most user inputs are designed to be via the keyboard or the barcode reader.
The keyboard is used for navigating within a screen, between screens, making selections and entering data inputs.
The barcode reader enables you to enter information via barcoded data into selected entry fields, (e.g., patient identification, specimen identification, color, clarity, etc.).

Data Entry Fields

Data entry fields are areas in a screen where information is entered. One screen can have several data entry fields, but only one field can be selected and active for entering data at a time. Pressing an alpha or a numeric key will input that character into the data entry field. If you exceed the number of allowable characters in a field, you cannot enter more characters until some characters have been deleted.
To select a data entry field, use the keyboard [] or [] keys to move the cursor up or down in the screen. To move back and forth between left and right columns, use the [Tab] key. The contents of the field will be reverse highlighted to show that they are selected or active.
To delete contents from a data field, select the field using the keyboard’s [] or [] or [Tab] keys, then press the [Delete] key.
To erase contents from data field one character at a time, select the field using the keyboard’s [] or [] or [Tab] keys, then press the [Backspace] key. The last character in the field will be deleted.

Toggle Fields

Toggle fields are fields setup in a circular fashion allowing you to choose one field out of a series of pre-setup fields (e.g., blank, trace, few, moderate, many, etc.). A toggle field will be indicated by a double­headed arrow []. Only one toggle field can be active at a given time.
To select a toggle field, use the keyboard keys [] or [] to move the cursor into the desired field.
To view the choices in a toggle field, use the keyboard keys [] or [] to advance through the selections. To switch back and forth from a left toggle field to a right toggle field, press the [Tab] key.
To confirm or lock in a selection, you may press the [Enter] key or use the keys [] or []. Either one will lock in the selection and advance you to the next field.
